Neutron Repulsion  

E-Print Network (OSTI)

Earth is connected gravitationally, magnetically and electrically to its heat source - a neutron star that is obscured from view by waste products in the photosphere. Neutron repulsion is like the hot filament in an incandescent light bulb. Excited neutrons are emitted from the solar core and decay into hydrogen that glows in the photosphere like a frosted light bulb. Neutron repulsion was recognized in nuclear rest mass data in 2000 as the overlooked source of energy, the keystone of an arch that locked together these puzzling space-age observations: 1.) Excess 136Xe accompanied primordial helium in the stellar debris that formed the solar system (Fig. 1); 2.) The Sun formed on the supernova core (Fig. 2); 3.) Waste products from the core pass through an iron-rich mantle, selectively carrying lighter elements and lighter isotopes of each element into the photosphere (Figs. 3-4); and 4.) Neutron repulsion powers the Sun and sustains life (Figs. 5-7). Together these findings offer a framework for understanding how: a.) The Sun generates and releases neutrinos, energy and solar-wind hydrogen and helium; b.) An inhabitable planet formed and life evolved around an ordinary-looking star; c.) Continuous climate change - induced by cyclic changes in gravitational interactions of the Sun's energetic core with planets - has favored survival by adaptation.

Chance and Chandra (and repulsive dark matter)  

E-Print Network (OSTI)

A few examples are given of Chandra's work on statistical and stochastic problems that relate to open questions in astrophysics, in particular his theory of dynamical relaxation in systems with inverse-square interparticle forces. The roles of chaos and integrability in this theory require clarification, especially for systems having a dominant central mass. After this prelude, a hypothetical form of repulsive bosonic dark matter is discussed. The repulsion leads to nontrivial thermodynamic behavior, including superfluidity, and would tend to suppress dynamical friction, greatly reducing the drag exerted on rotating galactic bars. However, this form of dark matter can probably be ruled out, at least for parameters that allow halos to reach thermal equilibria within a Hubble time. One combination of the particle mass and interparticle repulsion determines the minimum core radius of dark halos. Bounds on dark-matter collisionality inferred from the Bullet Cluster constrain a second combination. It is possible t...

Repulsive Casimir Effect with Chern insulators  

E-Print Network (OSTI)

We theoretically predict that the Casimir force in vacuum between two Chern insulator plates can be repulsive (attractive) at long distances whenever the sign of the Chern numbers characterizing the two plates are opposite (equal) and can be further tuned to attraction by electrostatic doping. We calculate and take into account the full optical response of the plates and argue that such repulsion is a general phenomena for these systems as it relies on the quantized zero frequency Hall conductivity. We discuss the possibility of achieving repulsion with thin films of Cr-doped (Bi,Sb)$_2$Te$_3$, that were recently discovered to be Chern insulators with quantized Hall conductivity and point towards multi-orbital systems as a route to realize this novel phenomenon.

Supermassive galactic centre with repulsive gravity  

E-Print Network (OSTI)

Repulsive gravity has its origin in the 1939 article of Oppenheimer and Snyder which describes a collapsar, that is an idealized star of non-interacting material (dust) collapsing under its own gravity. The stellar material has a final state resembling a football, that is a significant part of it is concentrated in a thin surface shell. An interior pressure is exerted by the strong gravitational field, equivalent to a negative mass. However, the OS solution has been misunderstood, the shell's position being incorrectly identified with the "event horizon" in black-hole theory. While half the material is concentrated in a shell occupying a small fraction of the radius, some material is spread throughout the interior, unlike the concentration in a black hole's singularity. We deal with the singularity in density at the shell surface, by including Fermi pressure of degenerate electrons for a shell density comparable to a solar mass-sized white dwarf. Because the high-density region is concentrated in a shell, instead of at the centre as in a black hole, our conclusion is that repulsive gravity enables the existence of supermassive white dwarfs.

Dilution and resonance-enhanced repulsion in nonequilibrium fluctuation forces  

SciTech Connect

In equilibrium, forces induced by fluctuations of the electromagnetic field between electrically polarizable objects (microscopic or macroscopic) in vacuum are generically attractive. The force may, however, become repulsive for microscopic particles coupled to thermal baths with different temperatures. We demonstrate that this nonequilibrium repulsion can be realized also between macroscopic objects, as planar slabs, if they are kept at different temperatures. It is shown that repulsion can be enhanced by (i) tuning of material resonances in the thermal region and by (ii) reducing the dielectric contrast due to ''dilution''. This can lead to stable equilibrium positions. We discuss the realization of these effects for aerogels, yielding repulsion down to submicron distances at realistic porosities.

Dissipative particle dynamics with attractive and repulsive particle-particle interactions  

Science Conference Proceedings (OSTI)

In molecular dynamics simulations, a combination of short-range repulsive and long-range attractive interactions allows the behavior of gases, liquids, solids, and multiphase systems to be simulated. We demonstrate that dissipative particle dynamics (DPD) simulations with similar pairwise particle-particle interactions can also be used to simulate the dynamics of multiphase fluids. In these simulations, the positive, short-range, repulsive part of the interaction potentials were represented by polynomial spline functions such as those used as smoothing functions in smoothed particle hydrodynamics, and the negative long-range part of the interaction has the same form but a different range and amplitude. If a single spline function corresponding to a purely repulsive interaction is used, the DPD fluid is a gas, and we show that the Poiseuille flow of this gas can be described accurately by the Navier-Stokes equation at low Reynolds numbers. In a two-component system in which the purely repulsive interactions between different components are substantially larger than the purely repulsive intracomponent interactions, separation into two gas phases occurs, in agreement with results obtained using DPD simulations with standard repulsive particle-particle interactions. Finally, we show that a combination of short-range repulsive interactions and long-range attractive interactions can be used to simulate the behavior of liquid drops surrounded by a gas. Similar models can be used to simulate a wide range of processes such as multiphase fluid flow through fractures and porous media with complex geometries and wetting behaviors.

Hadron-Resonance Gas at Freeze-out: Reminder on Importance of Repulsive Interactions  

E-Print Network (OSTI)

An influence of the repulsive interactions on matter properties is considered within the excluded volume van der Waals hadron-resonance gas model. Quantitative results are presented for matter at the chemical freeze-out in central nucleus-nucleus collisions at relativistic energies. In particular, it is shown that repulsive interactions connected to non-zero size of created particles lead to a significant decrease of collision energy at which the net-baryon density has a maximum. A position of the transition point from baryon to meson dominated matter depends on the difference between baryon and meson hard-core radiuses.

Lateral superlattice solar cells  

DOE Green Energy (OSTI)

A novel structure which comprises of a lateral superlattice as the active layer of a solar cell is proposed. If the alternating regions A and B of a lateral superlattice ABABAB... are chosen to have a Type-II band offset, it is shown that the performance of the active absorbing region of the solar cell is optimized. In essence, the Type-II lateral superlattice region can satisfy the material requirements for an ideal solar cells active absorbing region, i.e. simultaneously having a very high transition probability for photogeneration and a very long minority carrier recombination lifetime.

Stability of a fully magnetized ferromagnetic state in repulsively interacting ultracold Fermi gases  

SciTech Connect

We construct a variational wave function to study whether a fully polarized Fermi sea of ultracold atoms is energetically stable against a single spin flip. Our variational wave function contains short-range correlations at least to the same level as Gutzwiller's projected wave function. For the Hubbard lattice model and the continuum model with pure repulsive interaction, we show that a fully polarized Fermi sea is generally unstable even for infinite repulsive strength. By contrast, for a resonance model, the ferromagnetic state is possible if the s-wave scattering length is positive and sufficiently large and the system is prepared to be orthogonal to the molecular bound state. However, we cannot rule out the possibility that more exotic correlations can destabilize the ferromagnetic state.

Stripes, Clusters, and Nonequilibrium Ordering for Bidisperse Colloids with Repulsive Interactions  

E-Print Network (OSTI)

We show that two-dimensional bidisperse assemblies of colloids with strictly repulsive interactions exhibit stripe, cluster, and partially crystallized states when driven over a quenched random substrate. The nonequilibrium states on a substrate are significantly more ordered than equilibrium states both with and without substrates. A minimum substrate strength is necessary to induce the nonequilibrium pattern formation. Our results suggest that a combination of driving and quenched disorder offers a new approach to controlling pattern formation in colloid mixtures.

On the consistency of a repulsive gravity phase in the early Universe  

E-Print Network (OSTI)

We exploit the possibility of existence of a repulsive gravity phase in the evolution of the Universe. A toy model with a free scalar field minimally coupled to gravity, but with the "wrong sign" for the energy and negative curvature for the spatial section, is studied in detail. The background solutions display a bouncing, non-singular Universe. The model is well-behaved with respect to tensor perturbations. But, it exhibits growing models with respect to scalar perturbations whose maximum occurs in the bouncing. Hence, large inhomogeneties are produced. At least for this case, a repulsive phase may destroy homogeneity, and in this sense it may be unstable. A newtonian analogous model is worked out; it displays qualitatively the same behaviour. The generality of this result is discussed. In particular, it is shown that the addition of an attractive radiative fluid does not change essentially the results. We discuss also a quantum version of the classical repulsive phase, through the Wheeler-de Witt equation in mini-superspace, and we show that it displays essentially the same scenario as the corresponding attractive phase.

Laterally bendable belt conveyor  

DOE Patents (OSTI)

An endless, laterally flexible and bendable belt conveyor particularly adapted for coal mining applications in facilitating the transport of the extracted coal up- or downslope and around corners in a continuous manner is disclosed. The conveying means includes a flat rubber belt reinforced along the middle portion thereof along which the major portion of the belt tension is directed so as to cause rotation of the tubular shaped belt when trammed around lateral turns thus preventing excessive belt bulging distortion between adjacent belt supports which would inhibit belt transport. Pretension induced into the fabric reinforced flat rubber belt by conventional belt take-up means supports the load conveyed when the belt conveyor is making lateral turns. The carrying and return portions of the belt are supported and formed into a tubular shape by a plurality of shapers positioned along its length. Each shaper is supported from above by a monorail and includes clusters of idler rollers which support the belt. Additional cluster rollers in each shaper permit the belt supporting roller clusters to rotate in response to the belt's operating tension imposed upon the cluster rollers by induced lateral belt friction forces. The freely rotating roller clusters thus permit the belt to twist on lateral curves without damage to itself while precluding escape of the conveyed material by effectively enclosing it in the tube-shaped, inner belt transport length.

Universal Short-Range Repulsion in the Baryon System Originating from the Confinement --Approach in String-Junction Model--  

E-Print Network (OSTI)

We show a way to unifiedly understand the origins of the repulsive core of baryon-baryon interaction and the universal repulsion of three-baryon interaction needed to avoid dramatic softening of the equation of state of neutron stars due to hyperon mixing. For this aim we adopt the string-junction model which embodies the essential aspects of the confinement in the baryon system confirmed by recent lattice QCD calculations. Key concept of this study lies in the recognition that baryonic short-range repulsion appears as the latent effect implying the energy necessary for full overlap of baryons, for the confinement to persist at such situation. Numerical results are shown and related problems are discussed.

Phase diagram of Rydberg atoms with repulsive van der Waals interaction  

Science Conference Proceedings (OSTI)

We report a quantum Monte Carlo calculation of the phase diagram of bosons interacting with a repulsive inverse sixth power pair potential, a model for assemblies of Rydberg atoms in the local van der Waals blockade regime. The model can be parametrized in terms of just two parameters, the reduced density and temperature. Solidification happens to the fcc phase. At zero temperature, the transition density is found with the diffusion Monte Carlo method at density {rho}=3.9 (({Dirac_h}/2{pi}){sup 2}/mC{sub 6}){sup 3/4}, where C{sub 6} is the strength of the interaction. The solidification curve at nonzero temperature is studied with the path-integral Monte Carlo approach and is compared with transitions in corresponding harmonic and classical crystals. Relaxation mechanisms are considered in relation to present experiments.

High Island Densities and Long Range Repulsive Interactions: Fe on Epitaxial Graphene  

SciTech Connect

The understanding of metal nucleation on graphene is essential for promising future applications, especially of magnetic metals which can be used in spintronics or computer storage media. A common method to study the grown morphology is to measure the nucleated island density n as a function of growth parameters. Surprisingly, the growth of Fe on graphene is found to be unusual because it does not follow classical nucleation: n is unexpectedtly high, it increases continuously with the deposited amount ? and shows no temperature dependence. These unusual results indicate the presence of long range repulsive interactions. Kinetic Monte Carlo simulations and density functional theory calculations support this conclusion. In addition to answering an outstanding question in epitaxial growth, i.e., to find systems where long range interactions are present, the high density of magnetic islands, tunable with ?, is of interest for nanomagnetism applications.

Symbolic-numerical Algorithm for Generating Cluster Eigenfunctions: Tunneling of Clusters Through Repulsive Barriers  

E-Print Network (OSTI)

A model for quantum tunnelling of a cluster comprising A identical particles, coupled by oscillator-type potential, through short-range repulsive potential barriers is introduced for the first time in the new symmetrized-coordinate representation and studied within the s-wave approximation. The symbolic-numerical algorithms for calculating the effective potentials of the close-coupling equations in terms of the cluster wave functions and the energy of the barrier quasistationary states are formulated and implemented using the Maple computer algebra system. The effect of quantum transparency, manifesting itself in nonmonotonic resonance-type dependence of the transmission coefficient upon the energy of the particles, the number of the particles A=2,3,4, and their symmetry type, is analyzed. It is shown that the resonance behavior of the total transmission coefficient is due to the existence of barrier quasistationary states imbedded in the continuum.

A review of dynamic stability of repulsive-force maglev suspension systems  

DOE Green Energy (OSTI)

Vehicle dynamics and the need to satisfy ride quality requirements have long been recognized as crucial to the commercial success of passenger-carrying transportation systems. Design concepts for maglev systems are no exception. Early maglev investigators and designers were well aware of the importance of ride quality and took care to ensure that their designs would meet acceptable ride quality standards. In contrast, the dynamic stability of electrodynamic suspension (EDS) systems, which has obvious implications for system safety and cost as well as for ride quality, has not received nearly as much attention. Because of the well-known under-damped nature of EDS suspension systems and the observation of instabilities in laboratory-scale model systems, it is prudent to develop a better understanding of vehicle stability characteristics. The work reported in this was undertaken with the intention of summarizing information that has been accumulated worldwide and that is relevant to dynamic stability of repulsive-force maglev suspension systems, assimilating that information, and gaining an understanding of the factors that influence that stability. Included in the paper is a discussion and comparison of results acquired from some representative tests of large-scale vehicles on linear test tracks, together with analytical and laboratory-scale investigations of stability and dynamics of EDS systems. This paper will also summarize the R and D activities at Argonne National Laboratory (ANL) since 1991 to study the nature of the forces that are operative in an EDS system and the dynamic stability of such systems.

Equilibrium cluster phases and low-density arrested disordered states: The role of short-range attraction and long-range repulsion  

E-Print Network (OSTI)

We study a model in which particles interact with short-ranged attractive and long-ranged repulsive interactions, in an attempt to model the equilibrium cluster phase recently discovered in sterically stabilized colloidal systems in the presence of depletion interactions. At low packing fraction particles form stable equilibrium clusters which act as building blocks of a cluster fluid. We study the possibility that cluster fluids generate a low-density disordered arrested phase, a gel, via a glass transition driven by the repulsive interaction. In this model the gel formation is formally described with the same physics of the glass formation.

s-wave repulsion in the pion-nucleus optical potential and the subthreshold pion-nucleonT matrix  

SciTech Connect

A covariant theory of the pion-nucleus interaction has been used to calculate off-shell matrix elements of the first-order pion-nucleus optical potential in momentum space. The matrix elements are calculated for /sup 16/O and /sup 40/Ca, as a function of k, the momentum in the ..pi..-nucleus center-of-mass system, for W = m/sub ..pi../+M/sub N/. (As in our previous studies we have carried out a full integration over the Fermi motion of the target nucleons. Off-shell effects related to nuclear binding are treated carefully.) As this calculation is sensitively dependent upon the subthreshold ..pi..N T matrix, two different models for the T matrix are studied. One is the well known separable model of Londergan, McVoy, and Moniz. The second model includes terms describing the direct and crossed Born terms and therefore has the appropriate s- and u-channel nucleon poles. (In the calculations using this model both the pion and the nucleon are allowed to go off the mass shell.) The remaining part of the amplitude in the second model is represented by a separable form. For small k, the matrix elements of the optical potential calculated with these two models are significantly larger than those obtained when use is made of the fixed-scatterer approximation. Phenomenological optical potentials which describe low-energy pion-nucleus scattering data or pionic-atom data exhibit s-wave repulsion which is about 2--8 times that obtained from calculations made in the fixed-scatterer approximation. (The uncertainty in this enhancement factor reflects the uncertainty in the free-space values of the ..pi..N scattering lengths). We conclude that the explanation of a significant fraction of the s-wave repulsion in the low energy pion-nucleus interaction may lie in a careful treatment of off-shell effects using a good model for the subthreshold ..pi..N T matrix.

The Determinants of Homeonwership in Presence of Shocks Experienced by Mexican Households  

E-Print Network (OSTI)

Homeownership is both an individual and society objective, because of the positive neighborhood effects associated with areas of higher homeownership. To help realize these positive effects, the Mexican government has several programs directed to increasing homeownership. Many factors, however, may influence homeownership including shocks experienced by households. Shocks such as death in family, illness or accidents, unemployment, and business, crop, or livestock loss affect homeownership if households are unable to cushion the impact of the shock. Government income support programs, however, may help cushion the effect of a shock. The main objective is to determine how shocks that households’ experience and government income support programs influence homeownership in Mexico. A secondary objective is to determine how socio-demographic variables influence homeownership in Mexico. Based on the Random Utility Model, logit models of homeownership are estimated using data are from the 2002 Mexican National Survey on Living Levels of Households. Two models are estimated; with and without income. Income is excluded because of a large number of households that did not report income. Generally, inferences from the two models are similar. Homeownership appears to not be affected by shocks experienced by households. It appears households are able to cushion the impact of shocks. The two income support programs, the Program of Direct Rural Support of Mexico (PROGRESA) and the Program of Direct Rural Support of Mexico (PROCAMPO), appear to be increasing homeownership. These social welfare programs provide cash transfers to households. For whatever reason, PROGRESA has a larger effect on homeownership than PROCAMPO. Households with older heads have a larger probability of being a homeowner than households with younger heads. No statistically significance relationship exists between education and homeownership. Regional differences are seen in homeownership, with households located in the northwest region having a higher probability of homeownership than other regions. Differences in the significance of variable representing the household head’s gender, marital status, and occupation on homeownership exist between logit models that include and do not include current income. The most likely reason for these differences is interactions between the variables and a wealth effect.

Commanding lateral acceleration: a natural paradigm for automobile steering  

E-Print Network (OSTI)

This thesis describes a joystick automobile steering phics. controller which allows the driver to command the lateral acceleration of the vehicle directly, as opposed to controlling the front tire angle. The purpose of the controller is to improve joystick steering controls available to handicapped drivers, The controller design uses feedback from a chassis mounted accelerometer to sense actual vehicle lateral acceleration and cause the vehicle to achieve the lateral acceleration commanded by the driver. The thesis explains how a joystick and servo system utilizing the lateral acceleration command concept was analyzed, designed, built, and tested. Subjective and quantitative results are presented which show that a practical system was achieved and that commanding lateral acceleration is a natural way to steer a car. A1l test drivers preferred this system over joystick systems currently available to handicapped drivers which require the driver to command front wheel turn angle.

Hydrodynamics of undulatory fish schooling in lateral configurations  

E-Print Network (OSTI)

The thrust benefits of lateral configurations of two-dimensional undulating fish-like bodies are investigated using high-fidelity numerical simulation. The solution of the Navier--Stokes equations is carried out with a viscous vortex particle method. Configurations of tethered pairs of fish arranged side by side are studied by varying the lateral separation distance and relative phase difference. It is shown that, in mirroring symmetry, the fish in the pair augment each other's thrust even at relatively large separations (up to ten body lengths). At small distances, this augmentation is primarily brought about by a peristaltic pumping in the gap between the fish, whereas at larger distances, the thrust is affected by subtle changes in the vortex shedding at the tail due to interactions with the other fish. In cases without symmetric undulation, one fish always draws more benefit from the interaction than the other. Finally, lateral configurations with three fish are studied with mirroring symmetry between nei...

An Improved Method of Manufacturing Corrugated Boxes: Lateral Corrugator  

SciTech Connect

Paper physicists have known that a corrugated box constructed from outer liner sheets having a predominant fiber orientation aligned with the corrugating flute direction would have higher stiffness and crush resistance (per unit of fiber weight) than the conventional box construction. Such increased performance per unit of fiber weight could result in fiber reduction and energy savings for boxes having equivalent performance specifications. The goal of this project was to develop and demonstrate a commercially viable lateral corrugating process. This included designing and building a pilot lateral corrugator, testing and evaluating pilot machine made boxes, and developing a strategy for commercialization.

Science Conference Proceedings (OSTI)

We model structural transitions of small-size Wigner crystals in laterally compressed two-dimensional traps. Ground and metastable configurations are calculated and their transformations are linked to conspicuous changes in the heat capacity of the system. We show that various types of structural transitions are reflected by characteristic features in the behavior of the heat capacity. For deeper understanding, results produced by the Monte Carlo numerical calculations are compared to predictions of simple one-dimensional models.

Performance of a well with lateral and vertical wellbores  

E-Print Network (OSTI)

This thesis presents three major topics: analysis of pressure transient behavior of horizontal wells, analysis of pressure transient behavior of slanted wells, and performance analysis of wells with lateral and vertical wellbores. Additional analysis of actual well test data is also provided. For horizontal wells, we focus on analysis pressure solution for pseudoradial flow. Limited entry slanted wells are considered in this work by comparing wells with different angles and evaluating the performance. Modeling and performance analysis of a well with lateral and vertical wellbores is the last topic. The specific tasks achieved in this work include the following: We have compared four methods for analyzing pseudoradial flow found in the literature (Odeh and Babu, Joshi, Kuchuk et al., and Lichtenberger) and verified their methods using reservoir simulation. We found that the methods by Kuchuk et al. and Joshi are the most accurate while the method by Lichtenberger has the biggest error. We have modeled and examined the performance of slanted wells with different angles. The well length is equal to formation thickness and is kept constant. It has proven that the performance of slanted wells is proportional to the increase of the well angles only up to 60°. Further increasing the well angle will not make the well performance better than a vertical well. We have modeled and analyzed performance of combination wells. We compared the performance of vertical, slanted, and combination wells. Based on that comparison, the combination well has the best performance compared to other well geometries. By having a lateral section beside the vertical section, the performance of the well changes significantly. We have performed an analysis of actual injectivity test data from a well with lateral and vertical wellbores. The proper analysis obtained by correcting the pressure changes confirmed that the semilog straight line shows infinite acting radial flow. The permeability is 62.3 md, obtained by taking a correct slope of 260 psi/cycle. As of now, the radius of investigation is 8287 ft. It needs 7.9 years of injection to reach 850 psig of wellhead pressure.

Observation and implications of magnetic domains in lateral spin valves  

Science Conference Proceedings (OSTI)

Co/Cu/Co lateral spin valves (LSV), with Co being the topmost layer, are in situ prepared and measured under ultrahigh vacuum conditions. The clean process yields a non-local spin signal of 0.9 m{Omega}. Scanning electron microscopy with polarization analysis (SEMPA) reveals domain structures in both magnetic electrodes that depend on the LSV dimensions. The spin signal correlates to SEMPA images as well as the anisotropic magnetoresistance of both Co magnets, revealing a strong impact of multi-domain states on the spin signal.

Lateral Distribution for Aligned Events in Muon Groups Deep Underground  

E-Print Network (OSTI)

The paper concerns the so-called aligned events observed in cosmic rays. The phenomenon of the alignment of the most energetic subcores of gamma-ray--hadron ($\\gamma-h$) families (particles of the highest energies in the central EAS core) was firstly found in the "Pamir" emulsion chamber experiment and related to a coplanar particle production at $E_0>10^{16}$ eV. Here a separation distribution (distances between pairs of muons) for aligned events has been analyzed throughout muon groups measured by Baksan Underground Scintillation Telescope (BUST) for threshold energies $0.85 \\div 3.2$ TeV during a period of 7.7 years. Only muon groups of multiplicity $m\\geq 4$ with inclined trajectories for an interval of zenith angles $50^\\circ - 60^\\circ$ were selected for the analysis. The analysis has revealed that the distribution complies with the exponential law. Meanwhile the distributions become steeper with the increase of threshold energy. There has been no difference between the lateral distribution of all the groups and the distribution of the aligned groups.

We explore the feasibility of estimating primary cosmic ray composition at ultra high energies from the study of lateral age parameter of Extensive Air Showers (EAS) at ground level. Using different types of lateral distribution functions, we fit the particle density of simulated EAS to find the lateral age parameter. We discuss the chemical composition calculating the merit factor for each parameter distribution. The analysis considers three different primary particles (proton, iron and gamma), four different zenith angles (0{\\deg}, 15{\\deg}, 30{\\deg} and 45{\\deg}) and three primary energies (10^{17.25} eV, 10^{17.50} eV and 10^{17.75} eV).

Evaluation of concrete masonry unit walls for lateral natural phenomena hazards loads  

Science Conference Proceedings (OSTI)

Older single-story facilities (Pre-1985 vintage) are commonly constructed of structural steel framing with concrete masonry unit (CMU) walls connected to columns and roof girders of the steel framing system. The CMU walls are designed for lateral wind and seismic loads (perpendicular to the wall) and transmit shear loads from the roof diaphragm to the foundation footings. The lateral loads normally govern their design. The structural framing system and the roof diaphragm system are straight forward when analyzing or upgrading the structure for NPH loads. Because of a buildings design vintage, probable use of empirical methodology, and poor design basis documentation (and record retention); it is difficult to qualify or upgrade CMU walls for lateral Natural Phenomena Hazards (NPH) loads in accordance with References 1, 2 and 3. This paper discusses three analytical approaches and/or techniques (empirical, working stress and yield line) to determine the collapse capacity of a laterally loaded CMU wall, and compares their results

The Tapestry of Life: Lateral Transfers of Heritable Elements - Scientific Meeting  

SciTech Connect

The Sackler Colloquium The Tapestry of Life: Lateral Transfers of Heritable Elements was held on December 12-13, 2005. What Darwin saw as a tree of life descending in a linear fashion, is now more accurately seen as a tapestry of life, an anastomosing network, with important lateral transfers of heritable elements among parallel lines of descent These transfers range in complexity from small insertion sequences, to whole genes, gene islands, and portions of whole genomes which may be combined in symbiogenesis. The colloquium brought together researchers, empirical and theoretical, working at all levels on genomics, comparative genomics, and metagenomics to identify common and differentiating features of lateral gene transfer and to examine their implications for science and for human concerns.

Lateral propagation of MeV electrons generated by femtosecond laser irradiation  

Science Conference Proceedings (OSTI)

The propagation of MeV electrons generated by intense (approx =10{sup 20} W/cm{sup 2}) femtosecond laser irradiation, in the lateral direction perpendicular to the incident laser beam, was studied using targets consisting of irradiated metal wires and neighboring spectator wires embedded in electrically conductive (aluminum) or resistive (Teflon) substrates. The K shell spectra in the energy range 40-60 keV from wires of Gd, Dy, Hf, and W were recorded by a transmission crystal spectrometer. The spectra were produced by 1s electron ionization in the irradiated wire and by energetic electron propagation through the substrate material to the spectator wire of a different metal. The electron range and energy were determined from the relative K shell emissions from the irradiated and spectator wires separated by varying substrate lateral distances of up to 1 mm. It was found that electron propagation through Teflon was inhibited, compared to aluminum, implying a relatively weak return current and incomplete space-charge neutralization. The energetic electron propagation in the direction parallel to the electric field of the laser beam was larger than perpendicular to the electric field. Energetic electron production was lower when directly irradiating aluminum or Teflon compared to irradiating the heavy metal wires. These experiments are important for the determination of the energetic electron production mechanism and for understanding lateral electron propagation that can be detrimental to fast-ignition fusion and hard x-ray backlighter radiography.

Goa, India Cyclic Lateral Response of Model Pile Groups in Clay  

E-Print Network (OSTI)

ABSTRACT: This paper presents the results of two-way cyclic lateral load tests conducted in the laboratory on the model pile groups embedded in soft clay. The purpose of this research work is to investigate the effects of spacing, number of cycles of loading and cyclic load level on the pile group behaviour in clay. A pneumatic system is used to simulate cyclic loading typical of wave loading. Similitude laws are adhered to in selecting the material and size of the model piles. Piles are instrumented so that bending moments developed along the piles can be calculated. The results emphasized highly nonlinear nature of load-deflection behaviour. Group interaction effect under cyclic lateral loading is predominant for groups with spacing to diameter ratio less than 7. It is found that the cyclic load levels exceeding 0.5 times of static ultimate capacity, produce large deflections of the pile group due to gaps developed at the pile-soil interface, remoulding of clay and subsequent reduction in the stiffness. The bending moments in the piles are increased with the number of cycles and the location of maximum bending moment shifted downwards along the length of the pile. Numerical analysis using software ? GROUP is also carried out for closely spaced pile groups subjected to static lateral loads and the results are compared with the experimental ones. 1

A new approach to select multi-lateral well candidates using a fuzzy-logic based computer model  

E-Print Network (OSTI)

Multi-Lateral technology is defined as the drilling and completion of more than one wellbore from a single "mother" hole. The benefits of having multiple boreholes in a single well include increased flow rates, increased reserves, lower production costs, and improved drainage patterns or efficiencies. Candidate selection for multi-lateral technology has not been standardized and few literature references exist that can help individuals plan a multi-lateral well. Multilateral well candidate selection is usually tied to the results of a detailed and complex reservoir analysis. In many cases, small and independent companies are reluctant to apply multi-lateral technology without conducting a detailed economic analysis. In this research, we have developed a new easy, simple and fast, yet technically sound, method to screen candidate wells for possible application of multi-lateral technology. The new screening method is based on the simulation of human thinking by using a fuzzy logic model. This fuzzy logic model was built based on the personal experiences of industry experts in multi-lateral technology, as well as existing case histories of applications of multi-lateral technology found in the literature. The new model determines the best type of primary well configuration, choosing from a vertical well, horizontal well or a multi-lateral well. If the model suggests a multi-lateral well as the most appropriate option, the model then determ-nines the best multi-lateral configuration, choosing from a dual-opposed completion, a planar completion or a stacked completion. The output from the model is the level of confidence that the selected well configuration will be a technical success, based on the knowledge and experience used to build the model. The model was validated with four successful cases of application of multi-lateral technology published in the literature. The multi-lateral fuzzy logic model can be used to analyze the possibilities of applying multi-lateral technology for specific reservoir situations, limited to oil, onshore reservoirs composed of a single type of matrix. The model, however, should not be relied upon as the only screening tool. Numerical reservoir and economic models must also be used to determine expected well performance and to compute detailed economic analysis of all possible options.

No magnetic XMCD contrast was observed at the Cu L{sub 3} absorption edge, which should directly image the spin accumulation in Cu. Although electrical transport measurements in a non-local geometry clearly detected the spin accumulation in Cu, which remained unchanged during illumination with circular polarized x-rays at the Co and Cu L{sub 3} absorption edges.

Simulation and testing of a lateral, microfabricated electron-impact ion source  

Science Conference Proceedings (OSTI)

Simulation and experimental testing of a miniaturized, lateral, electron-impact ionization source are reported. Modeling and subsequent optimization of the device design led to a tenfold improvement in the performance of the device in comparison with earlier designs. Increased electron current contributing to ionization and increased ion collection efficiency are believed to be the main factors responsible for this improvement. SIMION software was used to model the behavior of the devices and understand the improvement in performance. The ion source can operate in a wide pressure range from 0.1 to 100 mTorr and generate ion currents in excess of 1 {mu}A.

U.S. Energy Information Administration (EIA) Indexed Site

crude oil production expected to exceed oil imports later crude oil production expected to exceed oil imports later this year U.S. crude oil production is expected to surpass U.S. crude oil imports by the fourth quarter of this year. That would mark the first time since February 1995 that domestic crude oil output exceeds imports, according to the latest monthly energy outlook from the U.S. Energy Information Administration. The United States will still need to import crude oil to help meet domestic demand. However, total crude oil imports this year are on track to fall to their lowest level since 1997. U.S. oil production is expected to continue to rise over the next two years as imports fall. As a result, the share of total U.S. petroleum consumption met by net imports is forecast to fall to 32 percent next year, the lowest level since 1985 and nearly half the peak level of 60 percent seen in

Lateral Spectrum Splitting Concentrator Photovoltaics: Direct Measurement of Component and Submodule Efficiency  

Science Conference Proceedings (OSTI)

To achieve high energy conversion efficiency, a solar module architecture called lateral spectrum splitting concentrator photovoltaics (LSSCPV) is being developed. LSSCPV can concentrate available sunlight and laterally split a single beam into bands with different spectra for absorption by different solar cells with band gaps matched to the split spectrum. Test assemblies of a sample LSSCPV architecture were constructed, each of which contains four p-n junctions and two optical pieces. Independent experiments or simulations had been implemented on the components but by using optimal assumptions. In order to examine the actual performances of all the components, which are dependent on each other and the light source, direct outdoor measurements were made. A set of self-consistent efficiency definitions was articulated and a test bed was developed to measure the parameters required by the efficiency calculation. By comparing the component efficiency items derived from the outdoor measurement and the expected values based on independent simulations, the potential opportunities for efficiency improvement are determined. In the outdoor measurement at the University of Delaware, the optical component demonstrated 89.1% efficiency. Additional assemblies were tested at the National Renewable Energy Laboratory. One assembly demonstrated 36.7% submodule efficiency, which compares favorably with the 32.6% previously reported verified submodule efficiency.

Influence of lateral target size on hot electron production and electromagnetic pulse emission from laser-irradiated metallic targets  

SciTech Connect

The influences of lateral target size on hot electron production and electromagnetic pulse emission from laser interaction with metallic targets have been investigated. Particle-in-cell simulations at high laser intensities show that the yield of hot electrons tends to increase with lateral target size, because the larger surface area reduces the electrostatic field on the target, owing to its expansion along the target surface. At lower laser intensities and longer time scales, experimental data characterizing electromagnetic pulse emission as a function of lateral target size also show target-size effects. Charge separation and a larger target tending to have a lower target potential have both been observed. The increase in radiation strength and downshift in radiation frequency with increasing lateral target size can be interpreted using a simple model of the electrical capacity of the target.

LATERALLY PROPAGATING DETONATIONS IN THIN HELIUM LAYERS ON ACCRETING WHITE DWARFS  

SciTech Connect

Theoretical work has shown that intermediate mass (0.01 M{sub Sun} < M{sub He} < 0.1 M{sub Sun }) helium shells will unstably ignite on the accreting white dwarf (WD) in an AM CVn binary. For more massive (M > 0.8 M{sub Sun }) WDs, these helium shells can be dense enough (>5 Multiplication-Sign 10{sup 5} g cm{sup -3}) that the convectively burning region runs away on a timescale comparable to the sound travel time across the shell, raising the possibility for an explosive outcome rather than an Eddington limited helium novae. The nature of the explosion (i.e., deflagration or detonation) remains ambiguous, is certainly density dependent, and likely breaks spherical symmetry. In the case of detonation, this causes a laterally propagating front whose properties in these geometrically thin and low-density shells we begin to study here. Our calculations show that the radial expansion time of <0.1 s leads to incomplete helium burning, in agreement with recent work by Sim and collaborators, but that the nuclear energy released is still adequate to realize a self-sustaining laterally propagating detonation. These detonations are slower than the Chapman-Jouguet speed of 1.5 Multiplication-Sign 10{sup 9} cm s{sup -1}, but still fast enough at 0.9 Multiplication-Sign 10{sup 9} cm s{sup -1} to go around the star prior to the transit through the star of the inwardly propagating weak shock. Our simulations resolve the subsonic region behind the reaction front in the detonation wave. The two-dimensional nucleosynthesis is shown to be consistent with a truncated one-dimensional Zeldovich-von Neumann-Doering calculation at the slower detonation speed. The ashes from the lateral detonation are typically He rich, and consist of predominantly {sup 44}Ti, {sup 48}Cr, along with a small amount of {sup 52}Fe, with very little {sup 56}Ni and with significant {sup 40}Ca in carbon-enriched layers. If this helium detonation results in a Type Ia supernova, its spectral signatures would appear for the first few days after explosion.

Bound states at threshold resulting from Coulomb repulsion  

SciTech Connect

The eigenvalue absorption for a many-particle Hamiltonian depending on a parameter is analyzed in the framework of non-relativistic quantum mechanics. The long-range part of pair potentials is assumed to be pure Coulomb and no restriction on the particle statistics is imposed. It is proved that if the lowest dissociation threshold corresponds to the decay into two likewise non-zero charged clusters then the bound state, which approaches the threshold, does not spread and eventually becomes the bound state at threshold. The obtained results have applications in atomic and nuclear physics. In particular, we prove that an atomic ion with the critical charge Z{sub cr} and N{sub e} electrons has a bound state at threshold given that Z{sub cr} Element-Of (N{sub e}- 2, N{sub e}- 1), whereby the electrons are treated as fermions and the mass of the nucleus is finite.

Double quantum dot with tunable coupling in a Si MOS device with lateral geometry.  

Science Conference Proceedings (OSTI)

We report low-temperature transport measurements of a silicon metal-oxide-semiconductor (MOS) double quantum dot (DQD). In contrast to previously reported measurements of DQD's in Si MOS structures, our device has a lateral gate geometry very similar to that used by Petta et al. to demonstrate coherent manipulation of single electron spins. This gate design provides a high degree of tunability, allowing for independent control over individual dot occupation and tunnel barriers, as well as the ability to use nearby constrictions to sense dot charge occupation. Comparison of experimentally extracted capacitances between the dot and nearby gates with electrostatic modeling demonstrates the presence of disorder and the ability to partially compensate for this disorder by adjustment of gate voltages. We experimentally show gate-controlled tuning of the interdot coupling over a wide range of energies, an important step towards potential quantum computing applications.

Characterization of Motor Unit Behavior in Patients with Amyotrophic Lateral Sclerosis  

E-Print Network (OSTI)

Abstract — In this study, we investigated the behavior of active motor units identified via analysis of electromyographic (EMG) signals recorded from the first dorsal interosseous (FDI) muscle using a quadrifilar needle electrode. Data was collected from control subjects and patients with both lower (LMN) and upper (UMN) motor neuron dominant forms of amyotrophic lateral sclerosis (ALS). EMG recordings were gathered during isometric contractions reaching 20 or 50 % of the force output produced during a maximum voluntary contraction (MVC). Recordings were analyzed using available EMG decomposition software (EMGLAB). Results showed differences in mean motor unit firing rates between patients with ALS and control subjects. Differences were also observed between patients with LMN- and UMN-dominant forms of ALS. Motor unit substitution was observed in patients despite the contractions lasting just a few seconds. Finally, we observed that motor unit action potential (MUAP) waveforms recorded from patients were more complex than those recorded from control subjects as often observed in motor neuron diseases.

E-Print Network (OSTI)

The possible identification by INTEGRAL of the EGRET source 3EG J1736 ? 2908 with the active galactic nucleus GRS 1734?292 is discussed. The latter was discovered in 1990 and later identified with a Seyfert 1 galaxy. At the time of the compilation of the 3rd EGRET Catalog, it was not considered as a possible counterpart of the source 3EG J1736 ? 2908, which remained unidentified. A detailed multiwavelength study of the EGRET error circle is presented, by including archival radio, soft- and hard-X observations, suggesting that GRS1734?292 could be a likely counterpart of 3EG J1736 ? 2908, even though this poses very interesting questions about the

The A-bomb, 50 years later: The evolution of nuclear medicine  

Science Conference Proceedings (OSTI)

In the wake of the Hiroshima and Nagasaki bombings, the U.S. government began to invest heavily in its nuclear program. Nuclear medicine stood to gain from these postwar policies, but it also suffered some setbacks. Fifty years ago this month, two atomic bombs were dropped on Japan, killing thousands of civilians and ushering in a quick and final end to World War II. The beginning of the post-war era signaled the birth of nuclear medicine as it is widely applied today. In fact, the same nuclear reactor that produced elements for the A-bomb project was turned over for the mass production of radionuclides for medicine and industry. The link between the A-bomb and nuclear medicine, however, has always been a sensitive subject among nuclear physicians whose patients may associate radionuclide injections with mushroom clouds. Although this link is not justified, the government`s interest in developing nuclear technology following World War II did have a significant impact on nuclear medicine: on the upside, millions of federal dollars were funneled into the production of radionuclides for research and medicine. On the downside, Congress established the Atomic Energy Commission (AEC)-which later became the Nuclear Regulatory Commission (NRC)-to oversee safety issues, making nuclear medicine the only medical field regulated by a federal agency.

Interfacial instability induced by lateral vapor pressure fluctuation in bounded thin liquid-vapor layers  

E-Print Network (OSTI)

We study an instability of thin liquid-vapor layers bounded by rigid parallel walls from both below and above. In this system, the interfacial instability is induced by lateral vapor pressure fluctuation, which is in turn attributed to the effect of phase change: evaporation occurs at the hotter portion of the interface and condensation at the colder one. The high vapor pressure drives the liquid away and the low one pulls it up. A set of equations describing the temporal evolution of the interface of the liquid-vapor layers is derived. This model neglects the effect of mass loss or gain at the interface and guarantees the mass conservation of the liquid layer. The result of linear stability analysis of the model shows that the presence of the pressure dependence of the local saturation temperature suppresses the growth of long-wave disturbances. We find the stability criterion, which suggests that only slight temperature gradients are sufficient to overcome the stabilizing gravitational effect for a water an...

Global petrochemical industry experiencing cyclic downturn  

SciTech Connect

The current deterioration of the petrochemical industry-particularly in the U.S. and Western Europe-is a cause of great concern to operators and analysts alike. Although the rapidly developing Asian market will continue to be a major factor into the next century, the immediate global outlook is for a weak market. Chem Systems Inc., Tarrytown, N.Y., discussed these issues at its annual petrochemical conference, held Jan. 13-14 in Houston. One of the few optimistic predictions of the meetings gas that the harbingers of the next industry cycle already can be seen in the U.S. economic recovery, and slow-down in new project planning, and a reduction in fixed costs. The paper describes the US market; market structure; the trend toward capacity integration; product forecasts; factors affecting the prices of propylene, aromatics, and benzene; the Asian market (Japan, Korea, Taiwan, China, Asian countries); regional trade; and the European market.

Lateral Transfer of a Lectin-Like Antifreeze Protein Gene in Fishes  

E-Print Network (OSTI)

Fishes living in icy seawater are usually protected from freezing by endogenous antifreeze proteins (AFPs) that bind to ice crystals and stop them from growing. The scattered distribution of five highly diverse AFP types across phylogenetically disparate fish species is puzzling. The appearance of radically different AFPs in closely related species has been attributed to the rapid, independent evolution of these proteins in response to natural selection caused by sea level glaciations within the last 20 million years. In at least one instance the same type of simple repetitive AFP has independently originated in two distant species by convergent evolution. But, the isolated occurrence of three very similar type II AFPs in three distantly related species (herring, smelt and sea raven) cannot be explained by this mechanism. These globular, lectin-like AFPs have a unique disulfide-bonding pattern, and share up to 85 % identity in their amino acid sequences, with regions of even higher identity in their genes. A thorough search of current databases failed to find a homolog in any other species with greater than 40 % amino acid sequence identity. Consistent with this result, genomic Southern blots showed the lectin-like AFP gene was absent from all other fish species tested. The remarkable conservation of both intron and exon sequences, the lack of correlation between evolutionary distance and mutation rate, and the pattern of silent vs non-silent codon changes make it unlikely that the gene for this AFP pre-existed but was lost from most branches of the teleost radiation. We propose instead that lateral gene transfer has resulted in the occurrence of the type II AFPs in herring, smelt and sea raven and

Copper and Zinc Metallation Status of Copper Zinc Superoxide Dismutase form Amyotrophic Lateral Sclerosis Transgenic Mice  

Science Conference Proceedings (OSTI)

Mutations in the metalloenzyme copper-zinc superoxide dismutase (SOD1) cause one form of familial amyotrophic lateral sclerosis (ALS), and metals are suspected to play a pivotal role in ALS pathology. To learn more about metals in ALS, we determined the metallation states of human wild-type or mutant (G37R, G93A, and H46R/H48Q) SOD1 proteins from SOD1-ALS transgenic mice spinal cords. SOD1 was gently extracted from spinal cord and separated into insoluble (aggregated) and soluble (supernatant) fractions, and then metallation states were determined by HPLC inductively coupled plasma MS. Insoluble SOD1-rich fractions were not enriched in copper and zinc. However, the soluble mutant and WT SOD1s were highly metallated except for the metal-binding-region mutant H46R/H48Q, which did not bind any copper. Due to the stability conferred by high metallation of G37R and G93A, it is unlikely that these soluble SOD1s are prone to aggregation in vivo, supporting the hypothesis that immature nascent SOD1 is the substrate for aggregation. We also investigated the effect of SOD1 overexpression and disease on metal homeostasis in spinal cord cross-sections of SOD1-ALS mice using synchrotron-based x-ray fluorescence microscopy. In each mouse genotype, except for the H46R/H48Q mouse, we found a redistribution of copper between gray and white matters correlated to areas of high SOD1. Interestingly, a disease-specific increase of zinc was observed in the white matter for all mutant SOD1 mice. Together these data provide a picture of copper and zinc in the cell as well as highlight the importance of these metals in understanding SOD1-ALS pathology.

Quantifying one and two dimensional lateral heterogeneities in fluvio-deltaic reservoirs using 3-D seismic data  

Science Conference Proceedings (OSTI)

We document scale-invariant statistics and strong anisotropy in rock properties from well log and 3-D seismic data in fluvial/deltaic reservoirs in the El 330 Field, Gulf of Mexico. The scarcity of well log data in the lateral direction necessitates the use of lower resolution seismic data to quantify lateral heterogeneity. Spectral analysis of two dimensional seismic horizon slices and one dimensional traces extracted form the 3-D data cube reveal scale invariant behavior with a characteristic correlation parameter ([beta]) in both dimensions. This parameter captures the degree of correlation in profiles or surfaces ([beta]=0) for white noise. Two dimensional analysis of the horizon slice indicates a ([beta]) value of approximately 2.0 while analysis of one dimensional profiles from the same slice reveal an anisotropy along depositional strike and dip with ([beta]) values of 1.6 and 2.1, respectively. The higher correlation observed in the direction of stratigraphic dip may reflect the stratigraphic fabric associated with channel systems. This one dimensional lateral variability in seismic data also matches the variability in higher resolution horizontal well log data suggesting a scale invariant behavior over approximately 3 orders of magnitude (1-1000 feet). Different depositional environments within specific systems tracts may have characteristic correlation parameters that provide insight into one and two dimensional lateral variations of reservoir heterogeneity. Correlation parameters obtained in these environments may then be used to quantify rock fabric and provide constraints in the simulation of rock property fields in the inter-well region.

Field and numerical studies of tracer gas transport and surface gas tranfer in laterally uniform, partially stratified estuaries  

SciTech Connect

Techniques for determination of reaeration rates in natural waterbodies are reviewed. The tracer gas technique for reaeration rate determination offers many advantages over other existing methods and is widely used in rivers and streams. The tracer gas method seems to be the most promising of available techniques for estuarine reaeration rate determination. The two-dimensional late-rally averaged equations describing flow and transport in estuaries are derived and discussed. A laterally averaged numerical model of estaurine hydrodynamics and transport is modified so that tracer gas releases may be simulated. Field studies conducted as a part of the study are described. Two dye releases were made in the upper Houston Ship Channel; two dye tracer gas releases were later made in the same region. The data from these studies are presented and analyzed. Mechanical mixing by shipping traffic proved to be the predominant mixing mechanism and a hindrance to further studies at that site. An intensive field study was conducted in the Colorado River estuary. Field data included velocities, salinity profiles, water surface elevations, and dye concentration data from three dye releases. The data from this study are used to calibrate and test the numerical model of estuarine tracer gas transport.

A New 4H-SiC Lateral Merged Double Schottky (LMDS) Rectifier With Excellent Forward and Reverse Characteristics  

E-Print Network (OSTI)

The novel characteristics of a new Schottky rectifier structure, known as the lateral merged double Schottky (LMDS) rectifier, on 4H-SiC are explored theoretically and compared with those of the compatible conventional 4H-SiC Schottky rectifiers. The anode of the proposed lateral device utilizes the trenches filled with a high barrier Schottky (HBS) metal to pinch off a low barrier Schottky (LBS) contact during reverse bias. Numerical simulation of any such SiC structure is complicated by the fact that the thermionic emission theory predicts the reverse leakage current to be orders of magnitude smaller than the measured data. We, therefore, first propose a simple empirical model for barrier height lowering to accurately estimate the reverse leakage current in a SiC Schottky contact. The accuracy of the empirical model is verified by comparing the simulated reverse leakage current with the reported experimental results on different SiC Schottky structures. Using the proposed empirical model, the two-dimensional (2-D) numerical simulations reveal that the new LMDS rectifier demonstrates about three orders of magnitude reduction in the reverse leakage current and two times higher reverse breakdown voltage when compared to the conventional lateral low barrier Schottky (LLBS) rectifier while keeping the forward voltage drop comparable to that of the conventional LLBS rectifier. A unique feature of the 4H-SiC LMDS rectifier is that it exhibits a very sharp PiN diode-like reverse blocking characteristic in spite of the fact that only Schottky junctions are used in the structure. The reasons for the improved performance of the LMDS rectifier are analyzed and design tradeoff between the forward voltage drop and the reverse leakage current is provided by varying the device parame...

Lateral steam flow revealed by a pressure build-up test at the Matsukawa vapor-dominated geothermal field, Japan  

Science Conference Proceedings (OSTI)

Results and discussion of a pressure build-up test at the Matsukawa vapor-dominated geothermal field in north-east Japan are reported. Pressure build-up behavior of three dry steam wells was monitored at the wellhead in October 1986. The observed pressure gradient clearly shows the existence of a lateral steam flow from south-west to north-east in the reservoir. This result suggests that the vapor-dominated reservoir extends further south-west than it is currently being developed. These conclusions are supported by production records and chemical data.

Reducing the efficiency droop by lateral carrier confinement in InGaN/GaN quantum-well nanorods  

E-Print Network (OSTI)

Efficiency droop is a major obstacle facing high-power application of InGaN/GaN quantum-well (QW) light-emitting diodes. In this letter, we report the suppression of efficiency droop induced by density-activated defect recombination in nanorod structure of a-plane InGaN/GaN QWs. In the high carrier density regime, the retained emission efficiency in a dry-etched nanorod sample is observed to be over two times higher than that in its parent QW sample. We further argue that the improvement is a combined effect of the amendment contributed by lateral carrier confinement and the deterioration made by surface trapping.

Modulation during learning of the responses of neurones in the lateral hypothalamus to the sight of food, Exp  

E-Print Network (OSTI)

Recordings were made from single neurons in the lateral hypothalamus and substantia innominata of the rhesus and squirrel monkey during feeding. A population of these neurons which altered their firing rates while the monkeys looked at food but not at nonfood objects was investigated. Because the responses of these neurons must have been affected by the previous experience of the animals, the activity of the neurons was measured during tasks in which the monkeys learned whether or not objects which they saw were associated with food. During visual discrimination tests these neurons came to respond when the monkey saw one stimulus associated with food (e.g., a black syringe from which the animal was fed glucose), but not when the monkey saw a different stimulus which was not associated with food (e.g., a white syringe from which the animal was offered saline). During extinction tests these units ceased to respond when the monkey saw a visual stimulus such as a peanut if the peanut was repeatedly not given to the monkey to eat. The learning or extinction behavior approximately paralleled the response of the neurons. The findings that the neurons in the lateral hypothalamus and substantia innominata respond when a monkey is shown food only if he is hungry, and as shown here, if as a result of learning the visual stimulus signifies food, provide information on a part of the brain which may be involved in feeding. The findings are consistent with other data which suggest that the responses of these neurons are involved in the autonomic and/or behavioral reactions of the animal to the sight of food.

New Markov Model Approaches to Deciphering Microbial Genome Function and Evolution: Comparative Genomics of Laterally Transferred Genes  

SciTech Connect

Algorithmic methods for gene prediction have been developed and successfully applied to many different prokaryotic genome sequences. As the set of genes in a particular genome is not homogeneous with respect to DNA sequence composition features, the GeneMark.hmm program utilizes two Markov models representing distinct classes of protein coding genes denoted "typical" and "atypical". Atypical genes are those whose DNA features deviate significantly from those classified as typical and they represent approximately 10% of any given genome. In addition to the inherent interest of more accurately predicting genes, the atypical status of these genes may also reflect their separate evolutionary ancestry from other genes in that genome. We hypothesize that atypical genes are largely comprised of those genes that have been relatively recently acquired through lateral gene transfer (LGT). If so, what fraction of atypical genes are such bona fide LGTs? We have made atypical gene predictions for all fully completed prokaryotic genomes; we have been able to compare these results to other "surrogate" methods of LGT prediction.

The Lateral Trigger Probability function for the Ultra-High Energy Cosmic Ray Showers detected by the Pierre Auger Observatory  

E-Print Network (OSTI)

In this paper we introduce the concept of Lateral Trigger Probability (LTP) function, i.e., the probability for an extensive air shower (EAS) to trigger an individual detector of a ground based array as a function of distance to the shower axis, taking into account energy, mass and direction of the primary cosmic ray. We apply this concept to the surface array of the Pierre Auger Observatory consisting of a 1.5 km spaced grid of about 1600 water Cherenkov stations. Using Monte Carlo simulations of ultra-high energy showers the LTP functions are derived for energies in the range between 10^{17} and 10^{19} eV and zenith angles up to 65 degs. A parametrization combining a step function with an exponential is found to reproduce them very well in the considered range of energies and zenith angles. The LTP functions can also be obtained from data using events simultaneously observed by the fluorescence and the surface detector of the Pierre Auger Observatory (hybrid events). We validate the Monte-Carlo results showing how LTP functions from data are in good agreement with simulations.

Stratigraphic controls on lateral variations in the structural style of northeastern Brooks Range, Arctic National Wildlife Refuge, Alaska  

Science Conference Proceedings (OSTI)

The structural style of the range-front region of the northeastern Brooks Range in Arctic National Wildlife Refuge (ANWR) is strongly controlled by (1) the existence of detachment horizons in both pre-Mississippian rocks and the unconformably overlying Mississippian to Lower Cretaceous cover sequence, and (2) lithology and structural competency of the pre-Mississippian rocks. These variables strongly influence lateral changes in structural style. The Brooks Range of northwestern ANWR is dominated by a series of narrow linear anticlinoria, whereas in northeastern ANWR the Brooks Range is characterized by only two broad and strongly arcuate anticlinoria. In both areas, the anticlinoria are controlled by the geometry of a duplex bounded by a floor thrust in pre-Mississippian rocks and a roof thrust in the Kayak Shale, near the base of the cover sequence. In the west, where the pre-Mississippian partially consists of structurally competent carbonates, each anticlinorium marks a single horse in the duplex. However, in the east, pre-Mississippian rocks are relatively incompetent and each anticlinorium is cored by multiple horses. In the west, shortening above the roof thrust is by detachment folding, except where the shale detachment horizon is depositionally absent. In contrast, in eastern ANWR shortening above the roof thrust is by major thrust duplication of the entire cover sequence, perhaps due to lithology and thickness changes within the detachment horizon.

PRIORITY COMMUNICATION Maternal Stress Beginning in Infancy May Sensitize Children to Later Stress Exposure: Effects on Cortisol and Behavior*  

E-Print Network (OSTI)

neonatal environment can permanently alter an individual’s responses to stress. To demonstrate a similar phenomenon in humans, we prospectively examined the relationships of maternal stress beginning in infancy and concurrent stress on preschoolers ’ hypothalamic-pituitary-adrenal activity and later mental health symptoms. Methods: Salivary cortisol levels were assessed in 282 4.5-year-old children and 154 of their siblings. Maternal reports of stress were obtained when the children were ages 1, 4, and 12 months, and again at 4.5 years. Children’s mental health symptoms were assessed in first grade. Results: A cross-sectional analysis revealed that preschoolers exposed to high levels of concurrent maternal stress had elevated cortisol levels; however, a longitudinal analysis revealed that concurrently stressed children with elevated cortisol also had a history of high maternal stress exposure in infancy. Importantly, children exposed only to high levels of concurrent or early stress had cortisol levels that did not significantly differ from those never exposed to stress. Further analysis of the components of stress indicated that maternal depression beginning in infancy was the most potent predictor of children’s cortisol. We also found that preschoolers with high cortisol levels exhibited greater mental health symptoms in first grade. Conclusions: These results link the findings of preclinical studies to humans by showing that exposure to early maternal stress may sensitize children’s pituitary-adrenal responses to subsequent stress exposure.

Economic and Conservation Evaluation of Capital Renovation Projects: Hidalgo County Irrigation District No. 2 (San Juan) - Relining Lateral A - Final  

E-Print Network (OSTI)

Initial construction costs and net annual changes in operating and maintenance expenses are identified for a single-component capital renovation project proposed by Hidalgo County Irrigation District No. 2, (a.k.a. San Juan) to the North American Development Bank (NADBank) and Bureau of Reclamation. The proposed project involves relining “Lateral A” with a geomembrane and shotcrete cover. Both nominal and real estimates of water and energy savings and expected economic and financial costs of those savings are identified throughout the anticipated useful life for the proposed project. Sensitivity results for both the cost of water savings and cost of energy savings are presented for several important parameters. Annual water and energy savings forthcoming from the total project are estimated, using amortization procedures, to be 2,542 ac-ft of water per year and 551,738,646 BTUs (161,705 kwh) of energy per year. The calculated economic and financial cost of water savings is estimated to be $74.49 per ac-ft. The calculated economic and financial cost of energy savings is estimated to be $0.0003698 per BTU ($1.262 per kwh). In addition, expected real (vs nominal) values are indicated for the Bureau of Reclamation’s three principal evaluation measures specified in the United States Public Law 106-576 legislation. The initial construction cost per ac-ft of water savings measure is $57.76 per ac-ft of water savings. The initial construction cost per BTU (kwh) of energy savings measure is $0.0002661 per BTU ($0.908 per kwh). The ratio of initial construction costs per dollar of total annual economic savings is estimated to be -14.29.

A Devonian batholith marks the boundary between the eastern and western structural provinces. The thrust-controlled range front of eastern ANWR extends north of the batholith, suggesting that the batholith itself may be underlain by a thrust fault.

Integrated Lateral Flow Test Strip with Electrochemical Sensor for Quantification of Phosphorylated Cholinesterase: Biomarker of Exposure to Organophosphorus Agents  

SciTech Connect

An integrated lateral flow test strip with electrochemical sensor (LFTSES) device with rapid, selective and sensitive response for quantification of exposure to organophosphorus (OP) pesticides and nerve agents has been developed. The principle of this approach is based on parallel measurements of post-exposure and baseline acetylcholinesterase (AChE) enzyme activity, where reactivation of the phosphorylated AChE is exploited to enable measurement of total amount of AChE (including inhibited and active) which is used as a baseline for calculation of AChE inhibition. Quantitative measurement of phosphorylated adduct (OP-AChE) was realized by subtracting the active AChE from the total amount of AChE. The proposed LFTSES device integrates immunochromatographic test strip technology with electrochemical measurement using a disposable screen printed electrode which is located under the test zone. It shows linear response between AChE enzyme activity and enzyme concentration from 0.05 to 10 nM, with detection limit of 0.02 nM. Based on this reactivation approach, the LFTSES device has been successfully applied for in vitro red blood cells inhibition studies using chlorpyrifos oxon as a model OP agent. This approach not only eliminates the difficulty in screening of low-dose OP exposure because of individual variation of normal AChE values, but also avoids the problem in overlapping substrate specificity with cholinesterases and avoids potential interference from other electroactive species in biological samples. It is baseline free and thus provides a rapid, sensitive, selective and inexpensive tool for in-field and point-of-care assessment of exposures to OP pesticides and nerve agents.

Rapid and Sensitive Detection of Protein Biomarker Using a Portable Fluorescence Biosensor based on Quantum Dots and a Lateral Flow Test Strip  

Science Conference Proceedings (OSTI)

A portable fluorescence biosensor with rapid and ultrasensitive response for trace protein has been built up with quantum dots and lateral flow test strip. The superior signal brightness and high photostability of quantum dots are combined with the promising advantages of lateral flow test strip and resulted in high sensitivity, selectivity and speedy for protein detection. Nitrated ceruloplasmin, a significant biomarker for cardiovascular disease, lung cancer and stress response to smoking, was used as model protein to demonstrate the good performances of this proposed Qdot-based lateral flow test strip. Quantitative detection of nitrated ceruloplasmin was realized by recording the fluorescence intensity of quantum dots captured on the test line. Under optimal conditions, this portable fluorescence biosensor displays rapid responses for nitrated ceruloplasmin in wide dynamic range with a detection limit of 0.1ng/mL (S/N=3). Furthermore, the biosensor was successfully utilized for spiked human plasma sample detection with the concentration as low as 1ng/mL. The results demonstrate that the quantum dot-based lateral flow test strip is capable for rapid, sensitive, and quantitative detection of nitrated ceruloplasmin and hold a great promise for point-of-care and in field analysis of other protein biomarkers.

Approximation of lateral distribution of atmospheric Cherenkov light at different observation levels for different primary particles. Applications for cosmic ray studies  

E-Print Network (OSTI)

This work summarizes the results presented at 29th International Cosmic Ray Conference in Pune India. Generally the aim of this work is to obtain the lateral distribution of the atmospheric Cherenkov light in extensive air showers produced by different primary particles in wide energy range and at several observation levels and to fit the obtained lateral distributions. Using one large detector and partially modified CORSIKA code version are obtained the lateral distributions of Cherenkov light flux densities at several observation levels for different particle primaries precisely at 536 g/cm2 Chacaltaya, 700 g/cm2 Moussala and 875 g/cm2 Kartalska field observation levels for hadronic primaries and gamma quanta in the energy range 1011 eV-1016 eV. On the basis of the solution of over-determined inverse problem the approximation of these distributions is obtained. The same model function for all the primaries is used and for the different observation levels. The different model parameters for the different primaries and levels are obtained. The approximations are compared with polynomial approximation obtained with different method. Both approximations are used for detector efficiency estimation for the different experiments in preparation and estimation of the accuracy of the reconstruction techniques. At the same time inclined showers up to 30 degrees zenith angle are studied at Chacaltaya observation level. The obtained lateral distributions of vertical showers are compared with vertical showers model and the previously obtained approximation. This permits to adjust the reconstruction strategy and to study the model parameters behavior.

Human Errors as an Invaluable Source for Experienced Decision Making  

E-Print Network (OSTI)

: In this paper the traditional paradigm for learning and training of operators in complex systems is discussed and criticised. There is a strong influence (the doctrine of 'mental logic') coming from research carried out in artificial intelligence. The most well known arguments against the artificial intelligence approach are presented and discussed in relation to expertise, intuition and implicit knowledge. The importance of faults and errors are discussed to describe expertise, and how knowledge about unsuccessful behaviour influences the actual decision making process of experts. 1. Introduction In this paper we will discuss the importance of learning from unsuccessful behaviour. What percentage of unanticipated events (e.g., accidents) is caused by human error? This is a question that vexed researchers for years in the context of human interaction with complex systems. In general, incident surveys in a variety of industries attribute high percentages of critical events to ...

LATERAL OFFSET OF THE CORONAL MASS EJECTIONS FROM THE X-FLARE OF 2006 DECEMBER 13 AND ITS TWO PRECURSOR ERUPTIONS  

Science Conference Proceedings (OSTI)

Two GOES sub-C-class precursor eruptions occurred within {approx}10 hr prior to and from the same active region as the 2006 December 13 X4.3-class flare. Each eruption generated a coronal mass ejection (CME) with center laterally far offset ({approx}> 45 Degree-Sign ) from the co-produced bright flare. Explaining such CME-to-flare lateral offsets in terms of the standard model for solar eruptions has been controversial. Using Hinode/X-Ray Telescope (XRT) and EUV Imaging Spectrometer (EIS) data, and Solar and Heliospheric Observatory (SOHO)/Large Angle and Spectrometric Coronagraph (LASCO) and Michelson Doppler Imager (MDI) data, we find or infer the following. (1) The first precursor was a 'magnetic-arch-blowout' event, where an initial standard-model eruption of the active region's core field blew out a lobe on one side of the active region's field. (2) The second precursor began similarly, but the core-field eruption stalled in the side-lobe field, with the side-lobe field erupting {approx}1 hr later to make the CME either by finally being blown out or by destabilizing and undergoing a standard-model eruption. (3) The third eruption, the X-flare event, blew out side lobes on both sides of the active region and clearly displayed characteristics of the standard model. (4) The two precursors were offset due in part to the CME originating from a side-lobe coronal arcade that was offset from the active region's core. The main eruption (and to some extent probably the precursor eruptions) was offset primarily because it pushed against the field of the large sunspot as it escaped outward. (5) All three CMEs were plausibly produced by a suitable version of the standard model.

Method and an apparatus to control the lateral motion of a long metal bar being formed by a mechanical process such as rolling or drawing  

DOE Patents (OSTI)

An adjustable guide, includes two or more mechanisms each having a rotatable retaining element containing a retaining groove with a variable radius in its perimeter surface. The grooves form a guidance path to control the lateral, i.e. non-axial, motion of a long bar moving along a longitudinal axis during a production process.The diameter of the guidance path varies according to the variable radii of the grooves. The guidance path increases in size at a predetermined rate, from a point of origin to an end point on the retaining groove. Rotating the retaining elements causes the diameter of the retaining grooves to change so that the size of the guidance path can be changed to match the diameter of the bar being rolled, size of the guidance path can be changed to fit the diameter of a new bar rolled without having to exchange the guide for a different sized guide, reduce fiction between the bar and the guide, a media, such as compressed air, can be injected between the retaining elements via orifices.Each retaining element is attached to a mounting apparatus. The mounting apparatus can be fixed or flexible. The flexible mounting apparatus includes one or more springs and one or more shock absorbers. A force neutral position of the flexible mounting apparatus is designed to be located on the predetermined ideal bar path line. The flexible mounting apparatus dissipates kinetic energy from the bar thereby reducing the bar's lateral motion relative to the ideal bar path line.The damping ratio of the mounting apparatus can be adjustable to alter the product's vibration mode to enable better control of the bar's lateral motion.

Economic and Conservation Evaluation of Capital Renovation Projects: United Irrigation District of Hidalgo County (United) – Rehabilitation of Main Canal, Laterals, and Diversion Pump Station – Final  

E-Print Network (OSTI)

Initial construction costs and net annual changes in operating and maintenance expenses are identified for a three-component capital renovation project proposed by the United Irrigation District to the U.S. Bureau of Reclamation (USBR). The proposed project involves: installing 4.66 miles of pipeline in the Main Canal and Lateral 7N, installing 13.46 miles of pipeline in several laterals and sub-laterals, and rehabilitating the District’s Rio Grande diversion pumping plant. Both nominal and real estimates of water and energy savings and expected economic and financial costs of those savings are identified throughout the anticipated useful lives for all three components. Sensitivity results for both the cost of saving water and the cost of saving energy are presented for several important parameters. Annual water and energy savings forthcoming from the total project are estimated, using amortization procedures, to be 1,522 ac-ft of water per year and 3,520,302,471 BTUs (1,031,742 kwh) of energy per year. The calculated economic and financial cost of saving water is estimated to be $341.51 per ac-ft. The calculated economic and financial cost of saving energy is estimated at $0.0001574 per BTU ($0.537 per kwh). In addition, real (vs. nominal) values are estimated for the USBRs three principal evaluation measures specified in the U.S. Public Law 106-576. The aggregate initial construction cost per ac-ft of water savings measure is $359.42 per ac-ft of water savings. The aggregate initial construction cost per BTU (kwh) of energy savings measure is $0.0003468 per BTU ($1.183 per kwh). The aggregate ratio of initial construction costs per dollar of total annual economic savings is estimated to be -3.551.

2 {mu}m laterally coupled distributed-feedback GaSb-based metamorphic laser grown on a GaAs substrate  

SciTech Connect

We report a type-I GaSb-based laterally coupled distributed-feedback (DFB) laser grown on a GaAs substrate operating continuous wave at room temperature. The laser structure was designed to operate near a wavelength of 2 {mu}m and was grown metamorphically with solid-source molecular beam epitaxy. The device was fabricated using a 6th-order deep etch grating structure as part of the sidewalls of the narrow ridge waveguide. The DFB laser emits total output power of up to 40 mW in a single longitudinal mode operation at a heat-sink temperature of 20 Degree-Sign C.

Band gap tunability of molecular beam epitaxy grown lateral composition modulated GaInP structures by controlling V/III flux ratio  

Science Conference Proceedings (OSTI)

Lateral composition modulated (LCM) GaInP structures were grown on (001) GaAs substrate by molecular beam epitaxy with different V/III flux ratios. Band gap of LCM structures could be tuned from 1.93 eV to 1.83 eV by decreasing flux ratio while maintaining the same photoluminescence intensity, enhanced light absorption, and widened absorption spectrum. It is shown that for band gap tuning of LCM structures, flux ratio adjustment is a more viable method compared to growth temperature adjustment.

Loss tangent imaging: Theory and simulations of repulsive-mode tapping atomic force microscopy  

Science Conference Proceedings (OSTI)

An expression for loss tangent measurement of a surface in amplitude modulation atomic force microscopy is derived using only the cantilever phase and the normalized cantilever amplitude. This provides a direct measurement of substrate compositional information that only requires tuning of the cantilever resonance to provide quantitative information. Furthermore, the loss tangent expression incorporates both the lost and stored energy into one term that represents a fundamental interpretation of the phase signal in amplitude modulation imaging. Numerical solutions of a cantilever tip interacting with a simple Voigt modeled surface agree with the derived loss tangent to within a few percent.

Lateral Al{sub x}Ga{sub 1-x}N power rectifiers with 9.7 kV reverse breakdown voltage  

SciTech Connect

Al{sub x}Ga{sub 1-x}N (x=0--0.25) Schottky rectifiers were fabricated in a lateral geometry employing p{sup +}-implanted guard rings and rectifying contact overlap onto an SiO{sub 2} passivation layer. The reverse breakdown voltage (V{sub B}) increased with the spacing between Schottky and ohmic metal contacts, reaching 9700 V for Al{sub 0.25}Ga{sub 0.75}N and 6350 V for GaN, respectively, for 100 {mu}m gap spacing. Assuming lateral depletion, these values correspond to breakdown field strengths of {<=}9.67x10{sup 5}Vcm{sup -1}, which is roughly a factor of 20 lower than the theoretical maximum in bulk GaN. The figure of merit (V{sub B}){sup 2}/R{sub ON}, where R{sub ON} is the on-state resistance, was in the range 94--268 MWcm-2 for all the devices.

IMPROVED MISCIBLE NITROGEN FLOOD PERFORMANCE UTILIZING ADVANCED RESERVOIR CHARACTERIZATION AND HORIZONTAL LATERALS IN A CLASS I RESERVOIR - EAST BINGER (MARCHAND) UNIT  

SciTech Connect

The cooperative agreement for this project was finalized and signed during April 2000. The official project start date was April 11, 2000. Initial reporting requirements, including the completion of a Project Management Plan, Milestone Plan and Log, and a Hazardous Substance Plan, were completed and submitted to the DOE in early May 2000. Work on the project tasks was initiated in May 2000. During the course of this budget period, efforts will focus on enhancing reservoir characterization work that had been in progress prior to the start of this grant project, incorporation of this information into an existing 3-D full-field compositional model, and utilization of a ''window area'' of the model (representing a selected pilot area) to evaluate the impacts of horizontal laterals on recovery in the miscible nitrogen flood. The ''window area'' model will also be used to design the most effective configuration and placement of the lateral sections. The following is a summary of progress made between April 11, 2000 and June 30, 2000.

Computational fluid dynamics analyses of lateral heat conduction, coolant azimuthal mixing and heat transfer predictions in a BR2 fuel assembly geometry.  

SciTech Connect

To support the analyses related to the conversion of the BR2 core from highly-enriched (HEU) to low-enriched (LEU) fuel, the thermal-hydraulics codes PLTEMP and RELAP-3D are used to evaluate the safety margins during steady-state operation (PLTEMP), as well as after a loss-of-flow, loss-of-pressure, or a loss of coolant event (RELAP). In the 1-D PLTEMP and RELAP simulations, conduction in the azimuthal and axial directions is not accounted. The very good thermal conductivity of the cladding and the fuel meat and significant temperature gradients in the lateral directions (axial and azimuthal directions) could lead to a heat flux distribution that is significantly different than the power distribution. To evaluate the significance of the lateral heat conduction, 3-D computational fluid dynamics (CFD) simulations, using the CFD code STAR-CD, were performed. Safety margin calculations are typically performed for a hot stripe, i.e., an azimuthal region of the fuel plates/coolant channel containing the power peak. In a RELAP model, for example, a channel between two plates could be divided into a number of RELAP channels (stripes) in the azimuthal direction. In a PLTEMP model, the effect of azimuthal power peaking could be taken into account by using engineering factors. However, if the thermal mixing in the azimuthal direction of a coolant channel is significant, a stripping approach could be overly conservative by not taking into account this mixing. STAR-CD simulations were also performed to study the thermal mixing in the coolant. Section II of this document presents the results of the analyses of the lateral heat conduction and azimuthal thermal mixing in a coolant channel. Finally, PLTEMP and RELAP simulations rely on the use of correlations to determine heat transfer coefficients. Previous analyses showed that the Dittus-Boelter correlation gives significantly more conservative (lower) predictions than the correlations of Sieder-Tate and Petukhov. STAR-CD 3-D simulations were performed to compare heat transfer predictions from CFD and the correlations. Section III of this document presents the results of this analysis.

EXPERIMENTAL NEUROLOGY t&668-677 (1976) Effects of Hunger on the Responses of Neurons in the Lateral Hypothalamus to the Sight and Taste of Food1  

E-Print Network (OSTI)

Recordings were made from single neurons in the monkey lateral hypothalamus and substantia innominata which had previously been shown to res’pond with an increase or decrease of their firing rates when the hungry monkey tasted food, and/or when he looked at food. It was found that the responsiveness of these neurons to food decreased over the course of a meal of glucose as satiety increased. When satiety, measured by whether the monkey rejected the glucose, was complete, there was no response of the neurons to the taste and/or to the sight of glucose. The spontaneous firing rates of these cells were not affected by the transitions from hunger to,satiety. This modulation of responsiveness to food of hypothalamic cells was specific to them in that it was not seen in cells in the globus pallidus which responded in relatimon to swallowing and mouth movements, or in cells in the visual inferotemporal cortex which responded when the monkey looked at the glucose-containing syringe. On the basis of this and other evidence it is suggested that the hypothalamic cells described here could be involved in the autonomic, the endocrine, and/or the feeding responses which occur when an animal sees or tastes food.

Striatal dopamine D2 receptor availability predicts the thalamic and medial prefrontal responses to reward in cocaine abusers three years later  

Science Conference Proceedings (OSTI)

Low levels of dopamine (DA) D2 receptor availability at a resting baseline have been previously reported in drug addicted individuals and have been associated with reduced ventral and dorsal prefrontal metabolism. The reduction in DA D2 receptor availability along with the reduced ventral frontal metabolism is thought to underlie compromised sensitivity to nondrug reward, a core characteristic of drug addiction. We therefore hypothesized that variability in DA D2 receptor availability at baseline will covary with dynamic responses to monetary reward in addicted individuals. Striatal DA D2 receptor availability was measured with [{sup 11}C]raclopride and positron emission tomography and response to monetary reward was measured (an average of three years later) with functional magnetic resonance imaging in seven cocaine-addicted individuals. Results show that low DA D2 receptor availability in the dorsal striatum was associated with decreased thalamic response to monetary reward; while low availability in ventral striatum was associated with increased medial prefrontal (Brodmann Area 6/8/32) response to monetary reward. These preliminary results, that need to be replicated in larger sample sizes and validated with healthy controls, suggest that resting striatal DA D2 receptor availability predicts variability in functional responses to a nondrug reinforcer (money) in prefrontal cortex, implicated in behavioral monitoring, and in thalamus, implicated in conditioned responses and expectation, in cocaine-addicted individuals.

Astroglial Inhibition of NF-kB Does Not Ameliorate Disease Onset and Progression in a Mouse Model for Amyotrophic Lateral Sclerosis (ALS)  

E-Print Network (OSTI)

Motor neuron death in amyotrophic lateral sclerosis (ALS) is considered a ‘‘non-cell autonomous’ ’ process, with astrocytes playing a critical role in disease progression. Glial cells are activated early in transgenic mice expressing mutant SOD1, suggesting that neuroinflammation has a relevant role in the cascade of events that trigger the death of motor neurons. An inflammatory cascade including COX2 expression, secretion of cytokines and release of NO from astrocytes may descend from activation of a NF-kB-mediated pathway observed in astrocytes from ALS patients and in experimental models. We have attempted rescue of transgenic mutant SOD1 mice through the inhibition of the NF-kB pathway selectively in astrocytes. Here we show that despite efficient inhibition of this major pathway, double transgenic mice expressing the mutant SOD1 G93A ubiquitously and the dominant negative form of IkBa (IkBaAA) in astrocytes under control of the GFAP promoter show no benefit in terms of onset and progression of disease. Our data indicate that motor neuron death in ALS cannot be prevented by inhibition of a single inflammatory pathway because alternative pathways are activated in the

IMPROVED MISCIBLE NITROGEN FLOOD PERFORMANCE UTILIZING ADVANCED RESERVOIR CHARACTERIZATION AND HORIZONTAL LATERALS IN A CLASS I RESERVOIR - EAST BINGER (MARCHAND) UNIT  

Science Conference Proceedings (OSTI)

The first horizontal well ever in the Marchand sandstone has been drilled. Although major difficulties arose with certain aspects of the drilling operation, a horizontal section of approximately 1300 was drilled. The section was left open hole as planned. The shales just above and between the Marchand sands appear to be very water-sensitive, requiring careful drilling practices. These shales were encountered in the middle part of the curve (45{sup o}-60{sup o}), which can be the most difficult part of a directional well to clean. Difficulties with these shales and cleaning this section led to a parted drill string, requiring a sidetrack. There were no major geologic ''surprises'', such as formation tops coming in much shallower or deeper than expected, or unexpected faults. Thin kaolinite beds were encountered in the horizontal section of the well. Previous descriptions of the mineralogy of this formation did not mention any kaolinite. The lateral extent of these beds is unknown. Completion of the well is under way. One additional injection profile was gathered during the quarter. Results are consistent with other recently profiles that show gas within the C Sand is overriding the oil and failing to sweep the deeper parts of the reservoir. International Reservoir Technologies, Inc. has completed the construction of the pilot area reservoir simulation model and the updating of historical production and injection data.

Replacement of Mushroom Cage Gastrostomy Tube Using a Modified Technique to Allow Percutaneous Replacement with an Endoscopic Tube in Patients with Amyotrophic Lateral Sclerosis  

Science Conference Proceedings (OSTI)

Radiologic inserted gastrostomy (RIG) is the preferred method in our institution for enteral feeding in amyotrophic lateral sclerosis (ALS). Skin-level primary-placed mushroom cage gastrostomy tubes become tight with weight gain. We describe a minimally invasive radiologic technique for replacing mushroom gastrostomy tubes with endoscopic mushroom cage tubes in ALS. All patients with ALS who underwent replacement of a RIG tube were included. Patients were selected for a modified replacement when the tube length of the primary placed RIG tube was insufficient to allow like-for-like replacement. Replacement was performed under local anesthetic and fluoroscopic guidance according to a preset technique, with modification of an endoscopic mushroom cage gastrostomy tube to allow percutaneous placement. Assessment of the success, safety, and durability of the modified technique was undertaken. Over a 60-month period, 104 primary placement mushroom cage tubes in ALS were performed. A total of 20 (19.2%) of 104 patients had a replacement tube positioned, 10 (9.6%) of 104 with the modified technique (male n = 4, female n = 6, mean age 65.5 years, range 48-85 years). All tubes were successfully replaced using this modified technique, with two minor complications (superficial wound infection and minor hemorrhage). The mean length of time of tube durability was 158.5 days (range 6-471 days), with all but one patient dying with a functional tube in place. We have devised a modification to allow percutaneous replacement of mushroom cage gastrostomy feeding tubes with minimal compromise to ALS patients. This technique allows tube replacement under local anesthetic, without the need for sedation, an important consideration in ALS.

Pigmented Creatine Deposits in Amyotrophic Lateral Sclerosis Central Nervous System Tissues Identified by Synchrotron Fourier Transform Infrared Microspectroscopy and X-ray Fluorescence Spectromicroscopy  

Science Conference Proceedings (OSTI)

Amyotrophic Lateral Sclerosis (ALS) is an untreatable, neurodegenerative disease of motor neurons characterized by progressive muscle atrophy, limb paralysis, dysarthria, dysphagia, dyspnae and finally death. Large motor neurons in ventral horns of spinal cord and motor nuclei in brainstem, large pyramidal neurons of motor cortex and/or large myelinated axons of corticospinal tracts are affected. In recent synchrotron Fourier Transform Infrared microspectroscopy (sFTIR) studies of ALS CNS autopsy tissue, we discovered a small deposit of crystalline creatine, which has a crucial role in energy metabolism. We have now examined unfixed, snap frozen, post-autopsy tissue sections of motor cortex, brain stem, spinal cord, hippocampus and substantia nigra from six ALS and three non-degenerated cases with FTIR and micro-X-ray fluorescence (XRF). Heterogeneous pigmented deposits were discovered in spinal cord, brain stem and motor neuron cortex of two ALS cases. The FTIR signature of creatine has been identified in these deposits and in numerous large, non-pigmented deposits in four of the ALS cases. Comparable pigmentation and creatine deposits were not found in controls or in ALS hippocampus and substantia nigra. Ca, K, Fe, Cu and Zn, as determined by XRF, were not correlated with the pigmented deposits; however, there was a higher incidence of hot spots (Ca, Zn, Fe and Cu) in the ALS cases. The identity of the pigmented deposits remains unknown, although the absence of Fe argues against both erythrocytes and neuromelanin. We conclude that elevated creatine deposits may be indicators of dysfunctional oxidative processes in some ALS cases.

Improved Miscible Nitrogen Flood Performance Utilizing Advanced Reservoir Characterization and Horizontal Laterals in a Class I Reservoir - East Binger (Marchand) Unit  

Science Conference Proceedings (OSTI)

The DOE-sponsored project at the East Binger Unit is an investigation into the benefits of reservoir characterization and horizontal wells in this particular setting of geologic and recovery method. The geologic setting is a tight (average porosity of 7% and average permeability of less than 1 millidarcy) Pennsylvanian-age sandstone at about 10,000 feet, and the recovery method is a miscible nitrogen flood. The projected oil recovery of the East Binger Unit, prior to the initiation of this project, was about 25%. Gravity segregation of nitrogen and crude oil was believed to be the principal cause of the poor sweep efficiency, and it was envisioned that with horizontal producing wells in the lower portion of the reservoir and horizontal injection wells near the top, the process could be converted from a lateral displacement process to a vertical displacement/gravity assisted process. Through the characterization and field development work completed in Budget Periods 1 and 2, Binger Operations, LLC (BOL) has developed a different interpretation of the sweep problem as well as a different approach to improving recovery. The sweep problem is now believed to be one of an areal nature, due to a combination of natural and hydraulic fracturing. Vertical wells have provided a much better economic return than have the horizontal wells. The natural and hydraulic fracturing manifests itself as a direction of higher permeability, and the flood is being converted to a line drive flood aligned with this orientation. Consistent with this concept, horizontal wells have been drilled along the line of the fracture orientation, such that hydraulic fracturing leads to 'longitudinal' fractures, in line with the wellbore. As such, the hydraulically fractured horizontal wells are not significantly different than hydraulically fractured vertical wells - save for the potential for a much longer fracture face. This Topical Report contains data from new wells, plus new and updated production, pressure, and gas analysis data that was not included in the Topical Report provided at the end of Budget Period 1. The analysis and interpretation of these data are provided in the many technical reports submitted throughout this project.

Lateral transport and far-infrared radiation of electrons in In{sub x}Ga{sub 1-x}As/GaAs heterostructures with the double tunnel-coupled quantum wells in a high electric field  

Science Conference Proceedings (OSTI)

It is shown that the far-infrared radiation of electrons in the selectively doped heterostructures with double tunnel-coupled quantum wells in high lateral electric fields strongly depends on the level of doping of the wells. At a high impurity concentration in a narrow well, higher than (1-2) x 10{sup 11} cm{sup -2}, the radiation is caused only by indirect intrasubband electron transitions. At a lower concentration, along with the indirect transitions, the direct intersubband transitions also contribute to the radiation. These transitions become possible in high electric fields due to the real-space electron transfer between the quantum wells.

Measurement of the absorption coefficient for light laterally propagating in light-emitting diode structures with In{sub 0.2}Ga{sub 0.8}N/GaN quantum wells  

SciTech Connect

A procedure for measuring the absorption coefficient for light propagating parallel to the surface of a GaN-based light emitting diode chip on a sapphire substrate is suggested. The procedure implies the study of emission from one end face of the chip as the opposite end face is illuminated with a light emitting diode. The absorption coefficient is calculated from the ratio between the intensities of emission emerging from the end faces of the sapphire substrate and the epitaxial layer. From the measurements for chips based on p-GaN/In{sub 0.2}Ga{sub 0.8}N/n-GaN structures, the lateral absorption coefficient is determined at a level of (23 {+-} 3)cm{sup -1} at a wavelength of 465 nm. Possible causes for the discrepancy between the absorption coefficients determined in the study and those reported previously are analyzed.

Mass composition of 10{sup 17}- to 10{sup 18}-eV primary cosmic rays according to data on the lateral distribution of radio emission from extensive air showers  

SciTech Connect

Experimental data obtained for the lateral distribution of radio emission from extensive air showers (EAS) at the array of Moscow State University (30-34 MHz) and the LOPES array (40-80 MHz) were comparedwith the results of calculations performed within amicroscopic approach based on aMonte Carlo simulation of EAS (CORSIKA code). The same experimental data were used to reconstruct the distribution of the depth of the EAS maximum at cosmic-ray energies in the range of 1017-1018 eV. The energy dependence of the depth of the EAS maximum was constructed for the case of data from the LOPES array, and the mass composition of cosmic rays was estimated for this case. From the resulting dependences, it follows that the mass composition shows a trend toward becoming lighter in the energy range being considered.

The Casimir Forces in a Single Conducting Cylindrical Cavity  

E-Print Network (OSTI)

We want to study the Casimir effect for a single conducting microscopic cylindrical cavity. The mathematical technique is based on the Green function of the geometry of the inside of the cavity, and the integral regularization is based on the plasma frequency cutoff for real conductors. Using the symmetric electromagnetic energy-momentum tensor, in terms of four potential, the total Casimir energy for the inside of the Cavity is calculated. Considering the fundamental cutoff applied by the uncertainty relations' limit on virtual particles' frequency in the quantum vacuum, it is shown that the contribution of the external (outside of the cavity) Casimir energy is negligible. Finally, the forces experienced by the lateral surface of the cavity and its circular bases are calculated. The resulting expressions show that these forces are repulsive. The numerical computation is done for the real problem of a cavity with a basis of a radius in the same order of its height at the scale of 100 nanometers made of the best conducting materials already known.

SDI spinoffs: research now, standards later  

Science Conference Proceedings (OSTI)

A major benefit of the Strategic Defense Initiative (SDI) its is potential for technological spinoffs. The lack of a consistent answer on the feasibility of developing an effective ballistic missile defense system may force Congress to look at the possible spinoffs in order to make a funding decision on SDI. Spinoffs have historically played an important role in providing industry with commercial applications, but there are also a number of unattractive aspects: unpredictability and possible suppression for national security reasons. Edward Teller is among those who promote X-ray lasers, while others support gamma-ray laser research. The possibility of SDI technology and spinoffs gives scientists and engineers a chance to participate in the development of new standards. 7 references.

We demonstrate that both the translational and angular accelerations exhibit very wide probability distributions, a manifestation of intermittency. The orientation of the angular velocity with respect to the trajectory, as well as the translational acceleration conditioned on the spinning velocity provide evidence of a lift force acting on the particle.

Transient heat and mass transfer in a drop experiencing absorption with internal circulation  

SciTech Connect

Absorption of gas and vapor into moving liquid droplet is frequently encountered in numerous applications in chemical industries and refrigeration technology. Here, transient heat and mass transfer associated with a moving liquid drop during absorption was numerically studied in this work. The roles played by the internal circulation inside the droplet and the exothermic heat effect were demonstrated. The numerical results reveal that the significant absorption enhancement by internal circulation becomes negligible with the increase of exothermic absorption heat. The highly exothermic system of LiBr/H{sub 2}O, which is used as a typical refrigerant/absorbent combination in commercial absorption heat pump (AHP), was selected as an example to illustrate this point.

Using multi-disciplinary strategic master facilities planning for organizations experiencing programmatic re-direction  

SciTech Connect

Facility master planning is critical to the future productivity of a laboratory and the quality of worklife for the laboratory staff. For organizations undergoing programmatic re-direction, a master facility planning approach linked to the organization`s strategic planning process is even more important. Major changes in an organization such as programmatic re-direction can significantly impact a broad range of variables which exceed the expertise of traditional planning teams, e.g., capacity variability, work team organization, organizational culture, and work process simplification. By expanding the diversity of the participants of the planning team, there is a greater likelihood that a research organization`s scientific, organizational, economic, and employees` needs can be meshed in the strategic plan and facility plan. Recent recommendations from facility planners suggest drawing from diverse fields in building multi-disciplinary planning teams: Architecture, engineering, natural science, social psychology, and strategic planning (Gibson,1993). For organizations undergoing significant operational or culture change, the master facility planning team should also include members with expertise in organizational effectiveness, industrial engineering, human resources, and environmental psychology. A recent planning and design project provides an example which illustrates the use of an expanded multi-disciplinary team engaged in planning laboratory renovations for a research organization undergoing programmatic re-direction. The purpose of the proposed poster session is to present a multi-disciplinary master facility planning process linked to an organization`s strategic planning process or organizational strategies.

Scaling of Macroscopic Properties of Porous Sediments Experiencing Compaction: Implications for Geothermal Gradient and Methane Inventory  

E-Print Network (OSTI)

Porous sediments in geological systems experience stress by the above-laying mass and consequent compaction, which may be significantly nonuniform across the massif. We derive scaling laws for the compaction of sediments of similar geological origin. With these laws, we evaluate the dependence of the transport properties of a fluid-saturated porous medium (permeability, effective molecular diffusivity, hydrodynamic dispersion, and thermal conductivity) on its porosity. In particular, we demonstrate irrelevance of the assumption of a uniform geothermal gradient for systems with nonuniform compaction and importance of the derived scaling laws for mathematical modelling of methane hydrate deposits, which are believed to have potential for impact on global climate change and Glacial-Interglacial cycles.

Thermo-Mechanical Analysis of Coated Particle Fuel Experiencing a Fast Control Rod Ejection Transient  

SciTech Connect

A rapid increase of the temperature and the mechanical stress is expected in TRISO coated particle fuel that experiences a fast Total Control Rod Ejection (CRE) transient event. During this event the reactor power in the pebble bed core increases significantly for a short time interval. The power is deposited instantly and locally in the fuel kernel. This could result in a rapid increase of the pressure in the buffer layer of the coated fuel particle and, consequently, in an increase of the coating stresses. These stresses determine the mechanical failure probability of the coatings, which serve as the containment of radioactive fission products in the Pebble Bed Reactor (PBR). A new calculation procedure has been implemented at the Idaho National Laboratory (INL), which analyzes the transient fuel performance behavior of TRISO fuel particles in PBRs. This early capability can easily be extended to prismatic designs, given the availability of neutronic and thermal-fluid solvers. The full-core coupled neutronic and thermal-fluid analysis has been modeled with CYNOD-THERMIX. The temperature fields for the fuel kernel and the particle coatings, as well as the gas pressures in the buffer layer, are calculated with the THETRIS module explicitly during the transient calculation. Results from this module are part of the feedback loop within the neutronic-thermal fluid iterations performed for each time step. The temperature and internal pressure values for each pebble type in each region of the core are then input to the PArticle STress Analysis (PASTA) code, which determines the particle coating stresses and the fraction of failed particles. This paper presents an investigation of a Total Control Rod Ejection (TCRE) incident in the 400 MWth Pebble Bed Modular reactor design using the above described calculation procedure. The transient corresponds to a reactivity insertion of $3 (~2000 pcm) reaching 35 times the nominal power in 0.5 seconds. For each position in the core the coated particle temperature and the stress history during a TCRE transient has been computed and the fuel failure probability has been quantified.

Microphase morphology in two dimensional fluids under lateral confinement  

E-Print Network (OSTI)

We study the effects of confinement between two parallel walls on a two dimensional fluid with competing interactions which lead to the formation of particle micro-domains at the thermodynamic equilibrium (microphases or microseparation). The possibility to induce structural changes of the morphology of the micro-domains is explored, under different confinement conditions and temperatures. In presence of neutral walls, a switch from stripes of particles to circular clusters (droplets) occurs as the temperature decreases, which does not happen in bulk. While the passage from droplets to stripes, as the density increases, is a well known phenomenon, the change of the stripes into droplets as an effect of temperature is rather unexpected. Depending on the wall separation and on the wall-fluid interaction parameters, the stripes can switch from parallel to perpendicular to the walls and also a mixed morphology can be stable.

A REALISTIC EXAMINATION OF COLD FUSION CLAIMS 24 YEARS LATER  

SciTech Connect

On March 29, 1989, chemists Martin Fleischmann and Stanley Pons announced they had discovered an effect whose explanation was required to lie in the realm of nuclear reactions. Their claim, and those subsequent to it of roughly similar nature, became known as ‘cold fusion’. Research continues to this day on this effect, but what has become clear is that whatever it is, it is not a conventional fusion process. Thus the ‘cold fusion’ moniker is somewhat inappropriate and many current researchers in the field prefer the term “Low Energy Nuclear Reactions (LENR)”, although other terms have been coined for it as well. the results developed out of the LENR research do in fact show something is happening to produce signals which might be interpreted as supporting nuclear reactions (which is what encourages and sustains LENR researchers), but which can also be interpreted via a set of unique and interesting conventional processes. The focus of this document is to describe and address recent objections to such processes so that subsequent LENR research can be guided to develop information that will determine whether either set of explanations has merit. It is hoped that criteria delineated herein will aid the USDOE and other agencies in determining if LENR proposals are meritorious and worthy of support or not.

India’s Credible Minimum Deterrence A Decade Later  

E-Print Network (OSTI)

Deterrence in the most conventional sense implies the making of military threats in order to prevent an adversary from taking aggressive actions (Buzan 1987). According to Barry Buzan (1987: 136), deterrence as a concept purports to stop an unwanted action by the adversary before they occur and encompasses both denial and the possibility of retaliation. The introduction of nuclear weapons into this complex dynamic of deterrence does not stabilise the crisis situation, as conventional wisdom suggests, but makes it even more threatening. The core of nuclear deterrence involves convincing the adversary that the cost of an undesirable action is more than the rewards. This requires a comprehensive understanding of not only the adversary’s motives, decision-making processes and objectives, but also one’s own capability to influence the calculus of costs and benefits that an adversary attaches to his own belligerence. Therefore, nuclear deterrence also takes into account the credibility of one’s own nuclear threat that is aimed at convincing the adversary that his belligerence will be ‘punished ’ by unacceptable damage through nuclear means. It is in the wake of this that India evolved its own nuclear doctrine which seeks to uphold the notion of credible minimum deterrence.

Influence Of Lateral Load Distributions On Pushover Analysis Effectiveness  

SciTech Connect

The effectiveness of two simple load distributions for pushover analysis recently proposed by the authors is investigated through a comparative study, involving static and dynamic analyses of seismic response of eccentrically braced frames. It is shown that in the upper floors only multimodal pushover procedures provide results close to the dynamic profile, while the proposed load patterns are always conservative in the lower floors. They over-estimate the seismic response less than the uniform distribution, representing a reliable alternative to the uniform or more sophisticated adaptive procedures proposed by seismic codes.

Lateral Capacity Exchange and Its Impact on Capacity Investment Decisions  

E-Print Network (OSTI)

We study the problem of capacity exchange between two …rms in anticipation of the mismatch between demand and capacity and its impact on …rm’s capacity investment decisions. For given capacity investment levels of the two …rms, we demonstrate how capacity price may be determined and how much capacity should be exchanged when either manufacturer acts as a Stackelberg leader in the capacity exchange game. By benchmarking against the centralized system, we show that a side payment may be used to coordinate the capacity exchange decisions. We then study the …rms’capacity investment decisions using a biform game framework in which capacity investment decisions are made individually and exchange decisions are made as in a centralized system. We demonstrate the existence and uniqueness of the Nash equilibrium capacity investment levels and study the impact of …rms’share of the capacity exchange surplus on their capacity investment levels.

E-Print Network (OSTI)

of excellence in research and education that has contributed greatly to the state-of-the-art in civil engineering. Completed in 1967 and extended in 1971, the structural testing area of the laboratory has a versatile strong-floor/wall and a three-story clear height that can be used to carry out a wide range of tests of building materials, models, and structural systems. The laboratory is named for Dr. Nathan M. Newmark, an internationally known educator and engineer, who was the Head of the Department of Civil Engineering at the University of Illinois [1956-73] and the Chair of the Digital Computing Laboratory [1947-57]. He developed simple, yet powerful and widely used, methods for analyzing complex structures and assemblages subjected to a variety of static, dynamic, blast, and earthquake loadings. Dr. Newmark received numerous honors and awards for his achievements, including the prestigious National Medal of Science awarded in 1968 by President Lyndon B. Johnson. He was also one of the founding members of the National Academy of Engineering.

Temporal Entropy Generation in the Viscous Layers of Laterally-converging Duct Flows  

SciTech Connect

Since insight into entropy generation is a key to increasing efficiency and thereby reducing fuel consumption and/or waste and -- for wall-bounded flows -- most entropy is generated in the viscous layer, we examine the transient behavior of its dominant contributor there for a non-canonical flow. New measurements in oil flow are presented for the effects of favorable streamwise mean pressure gradients on temporal entropy generation rates and, in the process, on key Reynolds-stress-producing events such as sweep front passage and on the deceleration/outflow phase of the overall bursting process. Two extremes have been considered: (1) a high pressure gradient, nearing "laminarization," and (2), for comparison, a low pressure gradient corresponding to many earlier experiments. In both cases, the peak temporal entropy generation rate occurs shortly after passage of the ejection/sweep interface. Whether sweep and ejection rates appear to decrease or increase with the pressure gradient depends on the feature examined and the manner of sampling. When compared using wall coordinates for velocities, distances and time, the trends and magnitudes of the transient behaviors are mostly the same. The main effects of the higher pressure gradient are (1) changes in the time lag between detections -- representing modification of the shape of the sweep front and the sweep angle with the wall, (2) modification of the magnitude of an instantaneous Reynolds shear stress with wall distance and (3) enlarging the sweeps and ejections. Results new for both low and high pressure gradients are the temporal behaviors of the dominant contribution to entropy generation; it is found to be much more sensitive to distance from the wall than to streamwise pressure gradient.

Stress reduction as a link between aerobic activity and academic performance experienced by undergraduate women through the use of the Student Recreation Center at Texas A&M University  

E-Print Network (OSTI)

The purpose of this study was to investigate the relationship between aerobic activity and academic performance through stress reduction using a student recreational facility. Research indicated that learning in college tends to focus on the academic aspects of the undergraduate experience - the classroom, laboratory, and the library - not other factors potentially affecting academic performance (Kuh et al., 1991). Forty women were randomly selected from the undergraduate population at Texas A&M University in order to analyze the relationship between aerobic activity and academic performance by measuring perceived stress levels. All participants completed an on-line stress questionnaire, the Perceived Stress Scale (PSS), every three weeks. Exam scores from an introductory sociology course and an educational statistics course were used for data analysis also. The experimental group (exercise group) used twelve weeks of regular aerobic exercise, while the control group (non-exercise) remained sedentary. During the twelve-week period, all participants self-reported data for additional qualitative data. Research findings of this study included: 1. The main benefit from aerobic activity was that women who exercised regularly felt more positive about academics and non-academic activities than women who did not exercise regularly. 2. There was no statistical significant difference between exam scores and academic performance of women who exercised regularly and those who did not exercise regularly. 3. There was no statistical significant difference between stress levels of women who exercised regularly and women who did not exercise regularly. Based on the findings of the study, researcher recommendations include: 1. Continue to investigate the changing demographics of college students - namely, age, sex, and non-traditional students. This study was limited to fulltime women between the ages of 18-24. Men and part-time students need to be included in a comparable study, providing campuses with more data that reflects the entire student population. 2. Explore additional areas in sociology and psychology that address exercise behavior trends in college students. Results from this study indicated that there are many variables, including stress, that affect college students in the behavioral sciences that can be attributed to differences in physical activity between sedentary and non-sedentary people. 3. Analyze health factors, which include amount of exercise, nutrition, and sleep patterns.

EXTRACTING PLANET MASS AND ECCENTRICITY FROM TTV DATA  

SciTech Connect

Most planet pairs in the Kepler data that have measured transit time variations (TTVs) are near first-order mean-motion resonances. We derive analytical formulae for their TTV signals. We separate planet eccentricity into free and forced parts, where the forced part is purely due to the planets' proximity to resonance. This separation yields simple analytical formulae. The phase of the TTV depends sensitively on the presence of free eccentricity: if the free eccentricity vanishes, the TTV will be in phase with the longitude of conjunctions. This effect is easily detectable in current TTV data. The amplitude of the TTV depends on planet mass and free eccentricity, and it determines planet mass uniquely only when the free eccentricity is sufficiently small. We analyze the TTV signals of six short-period Kepler pairs. We find that three of these pairs (Kepler 18, 24, 25) have a TTV phase consistent with zero. The other three (Kepler 23, 28, 32) have small TTV phases, but ones that are distinctly non-zero. We deduce that the free eccentricities of the planets are small, {approx}< 0.01, but not always vanishing. Furthermore, as a consequence of this, we deduce that the true masses of the planets are fairly accurately determined by the TTV amplitudes, within a factor of {approx}< 2. The smallness of the free eccentricities suggests that the planets have experienced substantial dissipation. This is consistent with the hypothesis that the observed pile-up of Kepler pairs near mean-motion resonances is caused by resonant repulsion. But the fact that some of the planets have non-vanishing free eccentricity suggests that after resonant repulsion occurred there was a subsequent phase in the planets' evolution when their eccentricities were modestly excited, perhaps by interplanetary interactions.

The Influence of Spatial Variation in Chromatin Density Determined by X-ray Tomograms on the Time to Find DNA Binding Sites  

E-Print Network (OSTI)

In this work we examine how volume exclusion caused by regions of high chromatin density might influence the time required for proteins to find specific DNA binding sites. The spatial variation of chromatin density within mouse olfactory sensory neurons is determined from soft X-ray tomography reconstructions of five nuclei. We show that there is a division of the nuclear space into regions of low-density euchromatin and high-density heterochromatin. Volume exclusion experienced by a diffusing protein caused by this varying density of chromatin is modeled by a repulsive potential. The value of the potential at a given point in space is chosen to be proportional to the density of chromatin at that location. The constant of proportionality, called the volume exclusivity, provides a model parameter that determines the strength of volume exclusion. Numerical simulations demonstrate that the mean time for a protein to locate a binding site localized in euchromatin is minimized for a finite, non-zero volume exclusivity. For binding sites in heterochromatin, the mean time is minimized when the volume exclusivity is zero (the protein experiences no volume exclusion). An analytical theory is developed to explain these results. The theory suggests that for binding sites in euchromatin there is an optimal level of volume exclusivity that balances a reduction in the volume searched in finding the binding site, with the height of effective potential barriers the protein must cross during the search process.

Density Functional Theory Study of Surface Carbonate Formation on BaO(001)  

Science Conference Proceedings (OSTI)

Periodic density functional theory calculations have been used to study the formation and stability of surface carbonate on BaO(001) upon CO2 exposures. CO2 adsorbs at Lewis basic Os site forming anionic surface carbonate ( ) species until one monolayer coverage (1ML). Certain amount of electrons has been transferred from the surface to CO2 after CO2 adsorption. The adsorption energy of CO2 decreases with the increasing coverage as a combinative result of the less electrons accepted by each adsorbed CO2 and the lateral repulsive interactions. At ?CO2 0.75 ML, dramatic surface reconstruction had been found for the parallel pattern of surface carbonates that initially arranged on BaO(001). Due to strong lateral repulsion between the surface carbonates, the surface reconstruction actually pulls the surface Ba atom out of the surface plane, suggesting a possible onset of phase transition from surface carbonate overlayer to crystalline bulk-like barium carbonate. Surface free energy calculations have been performed to study the stability of surface carbonate at different temperature and pressure conditions. Our calculations indicate that surface carbonates decompose at 850 K at low coverage. For the fully covered carbonate overlayer, surface carbonate will become unstable at about 600 K. This is in good agreement with previous experimental observations. Finally, the effect of surface hydroxyl on the stability of surface carbonate is investigated. At low hydroxyl coverage, the neighboring hydroxyl stabilizes surface carbonate. On the fully hydroxylated BaO surface, the chelating bicarbonate instead of surface carbonate is formed upon CO2 adsorption. This work, performed in the Institute for Interfacial Catalysis at Pacific Northwest National Laboratory (PNNL), was partially supported by a PNNL Laboratory Directed Research and Development (LDRD) project. Computing time was granted by the National Energy Research Scientific Computing Center (NERSC) under project No. m752, and also by the scientific user project (st30469) using the Molecular Science Computing Facility in the William R.

Twenty-five years later--an address prepared for delivery at the Solar Jubilee Dinner June 4, 1980, at Phoenix, Arizona  

SciTech Connect

The world-wide scientific organization which is known today as the International Solar Energy Society had its beginning in Phoenix 25 years ago, less than a mile from the hall in which the Solar Jubilee Banquet will be held. The Arizona civic leaders who founded the predecessor organization named it The Association for Applied Solar Energy and, as a Christmas present to the entire world, they incorporated it on December 24, 1954. Its aims were three-fold: to gather, compile, and disseminate information relating to solar energy; to foster research and education in fields related to solar energy; and to encourage the expansion and development of the applications of solar energy. An objective of this address is to show how the founders set out to accomplish these objectives and to let the hearers and readers of this address determine for themselves how effectively they have reached their goals.

Comparative Genomics Analysis and Phenotypic Characterization of Shewanella putrefaciens W3-18-1: Anaerobic Respiration, Bacterial Microcompartments, and Lateral Flagella  

Science Conference Proceedings (OSTI)

Respiratory versatility and psychrophily are the hallmarks of Shewanella. The ability to utilize a wide range of electron acceptors for respiration is due to the large number of c-type cytochrome genes present in the genome of Shewanella strains. More recently the dissimilatory metal reduction of Shewanella species has been extensively and intensively studied for potential applications in the bioremediation of radioactive wastes of groundwater and subsurface environments. Multiple Shewanella genome sequences are now available in the public databases (Fredrickson et al., 2008). Most of the sequenced Shewanella strains were isolated from marine environments and this genus was believed to be of marine origin (Hau and Gralnick, 2007). However, the well-characterized model strain, S. oneidensis MR-1, was isolated from the freshwater lake sediment of Lake Oneida, New York (Myers and Nealson, 1988) and similar bacteria have also been isolated from other freshwater environments (Venkateswaran et al., 1999). Here we comparatively analyzed the genome sequence and physiological characteristics of S. putrefaciens W3-18-1 and S. oneidensis MR-1, isolated from the marine and freshwater lake sediments, respectively. The anaerobic respirations, carbon source utilization, and cell motility have been experimentally investigated. Large scale horizontal gene transfers have been revealed and the genetic divergence between these two strains was considered to be critical to the bacterial adaptation to specific habitats, freshwater or marine sediments.

Later Outcomes and Alpha/Beta Estimate From Hypofractionated Conformal Three-Dimensional Radiotherapy Versus Standard Fractionation for Localized Prostate Cancer  

Science Conference Proceedings (OSTI)

Purpose: Now that the follow-up time has exceeded 5 years, an estimate of the {alpha}/{beta} ratio can be presented. The additional late outcomes in patients treated with three-dimensional conformal external beam radiotherapy for localized prostate cancer using a hypofractionated vs. a standard fractionation regimen are reported from this prospective nonrandomized contemporary comparison. Methods and Materials: A total of 114 nonrandomized patients chose hypofractionation delivered in 20 fractions of 3 Gy or 3.15 Gy (mean 3.06 Gy) for localized prostate cancer within a median overall time of 32 days (range, 29-49) using four fractions weekly. A total of 160 comparable patients were contemporarily treated within a median of 55 days (range 49-66). The median follow-up was 66 months (range, 24-95) for the hypofractionated arm and 63 months (range, 36-92) for the standard arm. The percentage of patients in the low-, medium-, and high-risk groups was 36%, 46%, and 18% in the hypofractionated arm and 44%, 50%, and 6% in standard arm (2 Gy), respectively. Results: The 5-year actuarial biochemical absence of disease (prostate-specific antigen nadir + 2 ng/mL) and disease-free survival rate was the same at 89% in both arms, making the {alpha}/{beta} calculation unambiguous. The point ratio of {alpha}/{beta} was 1.86 (95% confidence interval, 0.7-5.1 Gy). The 95% confidence interval was determined entirely by the binomial confidence limits in the numbers of patients. Rectal reactions of grade 3 and 4 occurred in 1 of 114 (hypofractionated) and 2 of 160 (standard) patients. Conclusions: The presented three-dimensional conformal regimen was acceptable, and the {alpha}/{beta} value was 1.8, in agreement with other very recent low meta-analyses (reviewed in the '' section).

One Decade Later: Trends and Disparities in the Application of Post-Mastectomy Radiotherapy Since the Release of the American Society of Clinical Oncology Clinical Practice Guidelines  

Science Conference Proceedings (OSTI)

Purpose: In 2001 ASCO published practice guidelines for post mastectomy radiotherapy (PMRT). We analyzed factors that influence the receipt of radiotherapy therapy and trends over time. Methods and Materials: We analyzed 8889 women who underwent mastectomy as primary surgical treatment for stage II or III breast cancer between 1995 and 2008 using data from the Kentucky Cancer Registry. We categorized patients according to ASCO group: group 1, PMRT not routinely recommended (T2, N0); group 2, PMRT controversial/evidence insufficient (T1-2, N1); group 3, PMRT recommended or suggested (T3-4 or N2-3). Probability of receiving PMRT was assessed using logistic regression. Results: Overall, 24.0% of women received PMRT over the study period. The rates of PMRT for group 1, 2, and 3 were 7.5%, 19.5%, and 47.3%, respectively. Since 2001, there was an increase in the use of PMRT (from 21.1%-26.5%, P70 years (vs. younger), rural Appalachia (vs. non-Appalachia) populations, and Medicaid (vs. privately insured) patients. Conclusions: ASCO guidelines have influenced practice in an underserved state; however PMRT remains underused, even for highest-risk patients. Barriers exist for elderly, rural and poor patients, which independently predict for lack of adequate care. Updated guidelines are needed to clarify the use of PMRT for patients with T1-2, N1 disease.

A multimodal approach for tracing lateralization along the olfactory pathway in the honeybee through electrophysiological recordings, morpho-functional imaging, and behavioural studies  

E-Print Network (OSTI)

Recent studies have revealed asymmetries between the left and right sides of the brain in invertebrate species. Here we present a review of a series of recent studies from our labs, aimed at tracing asymmetries at different stages along the honeybee's (Apis mellifera) olfactory pathway. These include estimates of the number of sensilla present on the two antennae, obtained by scanning electron microscopy, as well as electroantennography recordings of the left and right antennal responses to odorants. We describe investigative studies of the antennal lobes, where multi-photon microscopy is used to search for possible morphological asymmetries between the two brain sides. Moreover, we report on recently published results obtained by two-photon calcium imaging for functional mapping of the antennal lobe aimed at comparing patterns of activity evoked by different odours. Finally, possible links to the results of behavioural tests, measuring asymmetries in single-sided olfactory memory recall, are discussed.

Critical Casimir forces between homogeneous and chemically striped surfaces  

E-Print Network (OSTI)

Recent experiments have measured the critical Casimir force acting on a colloid immersed in a binary liquid mixture near its continuous demixing phase transition and exposed to a chemically structured substrate. Motivated by these experiments, we study the critical behavior of a system, which belongs to the Ising universality class, for the film geometry with one planar wall chemically striped, such that there is a laterally alternating adsorption preference for the two species of the binary liquid mixture, which is implemented by surface fields. For the opposite wall we employ alternatively a homogeneous adsorption preference or homogeneous Dirichlet boundary conditions, which within a lattice model are realized by open boundary conditions. By means of mean-field theory, Monte Carlo simulations, and finite-size scaling analysis we determine the critical Casimir force acting on the two parallel walls and its corresponding universal scaling function. We show that in the limit of stripe widths small compared with the film thickness, on the striped surface the system effectively realizes Dirichlet boundary conditions, which generically do not hold for actual fluids. Moreover, the critical Casimir force is found to be attractive or repulsive, depending on the width of the stripes of the chemically patterned surface and on the boundary condition applied to the opposing surface.

Multiscale Filler Structure in Simplified Industrial Nanocomposite Silica/SBR Systems Studied by SAXS and TEM  

E-Print Network (OSTI)

Simplified silica (Zeosil 1165 MP) and SBR (140k carrying silanol end-groups) nanocomposites have been formulated by mixing of a reduced number of ingredients with respect to industrial applications. The thermo-mechanical history of the samples during the mixing process was monitored and adjusted to identical final temperatures. The filler structure on large scales up to micrometers was studied by transmission electron microscopy (TEM) and very small-angle X-ray scattering (SAXS). A complete quantitative model extending from the primary silica nanoparticle (of radius \\approx 10 nm), to nanoparticles aggregates, up to micrometer-sized branches with typical lateral dimension of 150 nm is proposed. Image analysis of the TEM-pictures yields the fraction of zones of pure polymer, which extend between the branches of a large-scale filler network. This network is compatible with a fractal of average dimension 2.4 as measured by scattering. On smaller length scales, inside the branches, small silica aggregates are present. Their average radius has been deduced from a Kratky analysis, and it ranges between 35 and 40 nm for all silica fractions investigated here (\\phi_si = 8-21% vol.). A central piece of our analysis is the description of the interaggregate interaction by a simulated structure factor for polydisperse spheres representing aggregates. A polydispersity of 30% in aggregate size is assumed, and interactions between these aggregates are described with a hard core repulsive potential. The same distribution in size is used to evaluate the polydisperse form factor. Comparison with the experimental intensity leads to the determination of the average aggregate compacity (assumed identical for all aggregates in the distribution, between 31% and 38% depending on \\phi_si), and thus aggregation number (ca. 45, with a large spread). Because of the effect of aggregate compacity and of pure polymer zones, the volume fraction of aggregates is higher in the branches than \\phi_si. The repulsion between aggregates has a strong effect on the apparent isothermal compressibility: it leads to a characteristic low-q depression, which cannot be interpreted as aggregate mass decrease in our data. In addition, the reinforcement effect of these silica structures in the SBR-matrix is characterized with oscillatory shear and described with a model based on the same aggregate compacity. Finally, our results show that it is possible to analyze the complex structure of interacting aggregates in nanocomposites of industrial origin in a self-consistent and quantitative manner.

Effect of water-wall interaction potential on the properties of nanoconfined water  

E-Print Network (OSTI)

Much of the understanding of bulk liquids has progressed through study of the limiting case in which molecules interact via purely repulsive forces, such as a hard-core potential. In the same spirit, we report progress on the understanding of confined water by examining the behavior of water-like molecules interacting with planar walls via purely repulsive forces and compare our results with those obtained for Lennard-Jones (LJ) interactions between the molecules and the walls. Specifically, we perform molecular dynamics simulations of 512 water-like molecules which are confined between two smooth planar walls that are separated by 1.1 nm. At this separation, there are either two or three molecular layers of water, depending on density. We study two different forms of repulsive confinements, when the interaction potential between water-wall is (i) $1/r^9$ and (ii) WCA-like repulsive potential. We find that the thermodynamic, dynamic and structural properties of the liquid in purely repulsive confinements qualitatively match those for a system with a pure LJ attraction to the wall. In previous studies that include attractions, freezing into monolayer or trilayer ice was seen for this wall separation. Using the same separation as these previous studies, we find that the crystal state is not stable with $1/r^9$ repulsive walls but is stable with WCA-like repulsive confinement. However, by carefully adjusting the separation of the plates with $1/r^9$ repulsive interactions so that the effective space available to the molecules is the same as that for LJ confinement, we find that the same crystal phases are stable. This result emphasizes the importance of comparing systems only using the same effective confinement, which may differ from the geometric separation of the confining surfaces.

In cooperation with Minatom organizations Radon carries out R and D programs on treatment of simulated high level waste (HLW) as well. Radon scientists deal with a study of materials for LILW, HLW, and Nuclear Power Plants (NPP) wastes immobilization, and development and testing of processes and technologies for waste treatment and disposal. Radon is mostly experienced in LILW vitrification. This experience can be carried over to HLW vitrification especially in field of melting systems. The melter chosen as a basic unit for the vitrification plant is a cold crucible. Later on Radon experience in LILW vitrification as well as our results on simulated HLW vitrification are briefly described.

Influence of propagation on the coherent accumulation of excitation induced by an ultrashort pulse train  

SciTech Connect

We study the effects of propagation through an extended sample of two- and three-level atoms on the coherent accumulation of excitation by an ultrashort pulse train. In the two-level case, previous pulses in the train may prepare the medium such that a later pulse may experience amplification and absorption in different positions inside the sample. For a large number of pulses, the atomic medium may be saturated by the train, and some pulses propagate without experiencing either absorption or amplification. In general, absorption of the resonant pulse frequency during propagation compromises the accumulation efficiency. In the three-level case, the coherent accumulation of excitation leads to electromagnetically induced transparency of the pulse train, and the pulses exit the medium without any distortion in their temporal profile.

Fundamental concepts of digital image processing  

SciTech Connect

The field of a digital-image processing has experienced dramatic growth and increasingly widespread applicability in recent years. Fortunately, advances in computer technology have kept pace with the rapid growth in volume of image data in these and other applications. Digital image processing has become economical in many fields of research and in industrial and military applications. While each application has requirements unique from the others, all are concerned with faster, cheaper, more accurate, and more extensive computation. The trend is toward real-time and interactive operations, where the user of the system obtains preliminary results within a short enough time that the next decision can be made by the human processor without loss of concentration on the task at hand. An example of this is the obtaining of two-dimensional (2-D) computer-aided tomography (CAT) images. A medical decision might be made while the patient is still under observation rather than days later.

Stagflation -- Bose-Einstein condensation in the early universe  

E-Print Network (OSTI)

Our universe experienced the accelerated expansion at least twice; an extreme inflationary acceleration in the early universe and the recent mild acceleration. By introducing the Bose-Einstein condensation (BEC) phase of a boson field, we have been developing a unified model of dark energy (DE) and dark matter (DM) for the later mild acceleration. In this scenario, two phases of BEC (=DE) and normal gas (=DM) transform with each other through BEC phase transition. This unified model has successfully explained the mild acceleration as an attractor. We extend this BEC cosmology to the early universe without introducing new ingredients. In this scenario, the inflation is naturally initiated by the condensation of the bosons in the huge vacuum energy. This inflation and even the cosmic expansion eventually terminates exactly at zero energy density. We call this stage as stagflation. At this stagflation era, particle production and the decay of BEC take place. The former makes the universe turn into the standard h...

Safety apparatus for nuclear reactor to prevent structural damage from overheating by core debris  

DOE Patents (OSTI)

The invention teaches safety apparatus that can be included in a nuclear reactor, either when newly fabricated or as a retrofit add-on, that will minimize proliferation of structural damage to the reactor in the event the reactor is experiencing an overheating malfunction whereby radioactive nuclear debris might break away from and be discharged from the reactor core. The invention provides a porous bed or sublayer on the lower surface of the reactor containment vessel so that the debris falls on and piles up on the bed. Vapor release elements upstand from the bed in some laterally spaced array. Thus should the high heat flux of the debris interior vaporize the coolant at that location, the vaporized coolant can be vented downwardly to and laterally through the bed to the vapor release elements and in turn via the release elements upwardly through the debris. This minimizes the pressure buildup in the debris and allows for continuing infiltration of the liquid coolant into the debris interior.

Hadron interactions from SU(2) lattice QCD  

Science Conference Proceedings (OSTI)

We evaluate interhadron interactions in quenched two-color lattice QCD from Bethe-Salpeter amplitudes, concentrating on S-wave scattering states of two scalar diquarks (uC{gamma}5d). Between two identical scalar diquarks, we observe repulsion in short-range region. We define and evaluate the 'quark-exchange part' in the interaction, which is induced by adding quark-exchange diagrams, or equivalently, by introducing Pauli blocking among some of quarks. The repulsive force in short-distance region arises only from the 'quark-exchange part', and disappears when quark-exchange diagrams are omitted, which is qualitatively consistent with the constituent-quark model picture that a color-magnetic interaction among quarks is the origin of repulsion. We also find a universal long-range attractive force, which enters in any flavor channels of two scalar diquarks and whose interaction range and strength are quark-mass independent.

Three attractively interacting fermions in a harmonic trap: Exact solution, ferromagnetism, and high-temperature thermodynamics  

SciTech Connect

Three fermions with strongly repulsive interactions in a spherical harmonic trap constitute the simplest nontrivial system that can exhibit the onset of itinerant ferromagnetism. Here, we present exact solutions for three trapped, attractively interacting fermions near a Feshbach resonance. We analyze energy levels on the upper branch of the resonance where the atomic interaction is effectively repulsive. When the s-wave scattering length a is sufficiently positive, three fully polarized fermions are energetically stable against a single spin-flip, indicating the possibility of itinerant ferromagnetism, as inferred in the recent experiment. We also investigate the high-temperature thermodynamics of a strongly repulsive or attractive Fermi gas using a quantum virial expansion. The second and third virial coefficients are calculated. The resulting equations of state can be tested in future quantitative experimental measurements at high temperatures and can provide a useful benchmark for quantum Monte Carlo simulations.

On the Cosmic Nuclear Cycle and the Similarity of Nuclei and Stars  

E-Print Network (OSTI)

Repulsive interactions between neutrons in compact stellar cores cause luminosity and a steady outflow of hydrogen from stellar surfaces. Neutron repulsion in more massive compact objects made by gravitational collapse produces violent, energetic, cosmological events (quasars, gamma ray bursts, and active galactic centers) that had been attributed to black holes before neutron repulsion was recognized. Rather than evolving in one direction by fusion, nuclear matter on the cosmological scale cycles between fusion, gravitational collapse, and dissociation (including neutron-emission). This cycle involves neither the production of matter in an initial Big Bang nor the disappearance of matter into black holes. The similarity Bohr noted between atomic and planetary structures extends to a similarity between nuclear and stellar structures.

Exact Solution for Infinitely Strongly Interacting Fermi Gases in Tight Waveguides  

SciTech Connect

We present an exact analytical solution of the fundamental systems of quasi-one-dimensional spin-1/2 fermions with infinite repulsion for an arbitrary confining potential. The eigenfunctions are constructed by the combination of Girardeau's hard-core contacting boundary condition and group theoretical method, which guarantees the obtained states to be simultaneously the eigenstates of S and S{sub z} and satisfy antisymmetry under odd permutation. We show that the total ground-state density profile behaves like the polarized noninteracting fermions, whereas the spin-dependent densities display different properties for different spin configurations. We also discuss the splitting of the ground states for large but finite repulsion.

Anthony Wayne: The History and Archaeology of an Early Great Lakes Steamboat  

E-Print Network (OSTI)

The Great Lakes side-wheel steamboat Anthony Wayne was built in 1837 at Perrysburg, OH and participated in lakes shipping during a time when such vessels were experiencing their heyday. Designed as a passenger and cargo carrier, the steamer spent 13 years transporting goods and people throughout the Upper Lakes until succumbing to a boiler explosion while headed to Buffalo on 28 April 1850. The remains of Anthony Wayne were discovered in 2006 and two years later a collaborative project was begun for the purposes of documenting and assessing the present day condition of the wreck. Anthony Wayne is the oldest steamboat wreck on the Great Lakes to be studied by archaeologists and represents an important piece of maritime heritage that can aid researchers in understanding architectural and machinery specifics that are unknown to us today. This thesis presents the results of an archaeological and archival investigation of Anthony Wayne. Information pertaining to the discovery and significance of the vessel are presented, followed by descriptions of Perrysburg and its shipping industry, the steamer's owners, and how the vessel was built. The operational history of Anthony Wayne is then outlined chronologically, including ports of call, cargoes, masters, and incidents the steamer experienced. Details of the explosion and the aftermath of the sinking are then discussed, followed by a brief summary of other Great Lakes steamboat catastrophes from 1850 and why boilers explode. Focus then shifts to the two-year archaeological investigation, including project objectives, methodology, and findings. The construction specifics of the steamboat's hull, drive system, and associated artifacts are then presented, followed by post-project analysis and conclusions. A catalog of Great Lakes steam vessels, vessel enrollment documentation, the coroner's inquest following the disaster, and the initial dive report from the discoverers are furnished as appendices.

Government`s response to the competitiveness problem  

SciTech Connect

This paper presents an analysis of how the US government responded to the concern in the 1980`s that US companies were experiencing problems of competitiveness in international markets. By the mid 1980`s there was great and growing concern throughout the US that US companies were experiencing difficulties in international competition. Pressure on Congress to take action came from constituents seeking jobs and companies that would directly benefit (this usually means receive public money) from programs that Congress might initiate. The fact that most constituent calls to Congress were about job creation was lost in the on-rush of R&D performers seeking funds for their favorite R&D project. In response, Congress created the Advanced Technology Program, the Technology Transfer Initiative, and the Technology Reinvestment Project, expanded the responsibilities of ARPA/DARPA, increased funding for the Small Business Initiative, expanded the Manufacturing Extension Partnership, funded SEMATECH, and increased NSF funding for basic research at universities. Many of these programs were later criticized for being industrial welfare and several were cut-back or stopped. Retrospective analysis shows that few of these programs addressed the root cause of competitiveness difficulties. In fact, by the time most of these programs were in place, US companies were well on their way to correcting their competitiveness problems. In addition, few were relevant to companies` often expressed concerns about workforce training, regulatory costs, and access to foreign markets. Twenty percent reductions in health care costs, regulatory costs, and education costs could annually pump $500 billion into the US economy and make companies operating in the US much more competitive in international markets.

Relativistic mechanism of superconductivity  

E-Print Network (OSTI)

According to the theory of relativity, the relativistic Coulomb's force between an electron pair is composed of two parts, the main part is repulsive, while the rest part can be attractive in certain situations. Thus the relativistic attraction of an electron pair provides an insight into the mechanism of superconductivity. In superconductor, there are, probably at least, two kinds of collective motions which can eliminate the repulsion between two electrons and let the attraction being dominant, the first is the combination of lattice and electron gas, accounting for traditional superconductivity; the second is the electron gas themselves, accounting for high $T_c$ superconductivity. In usual materials, there is a good balance between the repulsion and attraction of an electron pair, the electrons are regarded as free electrons so that Fermi gas theory plays very well. But in some materials, when the repulsion dominates electron pairs, the electron gas will has a behavior opposite to superconductivity. In the present paper the superconducting states are discussed in terms of relativistic quantum theory in details, some significant results are obtained including quantized magnetic flux, London equation, Meissner effect and Josephson effect.

Searching for an Attractive Force in Holographic Nuclear Physics  

E-Print Network (OSTI)

We are looking for a holographic explanation of nuclear forces, especially the attractive forces. Recently, the repulsive hard core of a nucleon-nucleon potential was obtained in the Sakai-Sugimoto model, and we show that a generalized version of that model -- with an asymmetric configuration of the flavor D8 branes -- also has an attractive potential. While the repulsive potential stems from the Chern-Simons interactions of the U(2) flavor gauge fields in 5D, the attractive potential is due to a coupling of the gauge fields to a scalar field describing fluctuations of the flavor branes' geometry. At intermediate distances r between baryons -- smaller than R_KK=O(1)/M_{omega meson} but larger than the radius rho=R_KK/sqrt('t Hooft coupling) of the instanton at the core of a baryon -- both the attractive and the repulsive potentials behave as 1/r^2, but the attractive potential is weaker: Depending on the geometry of the flavor D8 branes, the ratio C=-V_attr/V_rep ranges from 0 to 1/9. The 5D scalar fields also affect the isovector tensor and spin-spin forces, and the overall effect is similar to the isoscalar central forces: V(r)->(1-C)*V(r). At longer ranges $r\\gtrsim R_{\\rm KK}$, we find that the attractive potential decays faster than the repulsive potential, so the net potential is always repulsive. This unrealistic behavior may be peculiar to the Sakai-Sugimoto-like models, or it could be a general problem of the large N_c limit inherent in holography.

The Age of PURPA Spawns the "Wind Farm" The Age of PURPA Spawns the "Wind Farm" The sustained high cost of conventional fuels together with heightened environmental concerns about air pollution led in 1978 to federal legislation - known as PURPA, the Public Utility Regulatory Policies Act - that encouraged private, non-utility investment in generating power from renewable energy sources. At that time, the first small-scale wind turbines were being sold by domestic manufacturers. Wind Farm at Crotched Mountain, NH, 1978. Photo courtesy of the University of Massachusetts.

Like many firsts, it was a failure: The developer overestimated the wind resource, and the turbines frequently broke. U.S. Windpower, which later changed its name to Kenetech, subsequently developed wind farms in California, and after experiencing machine failure there too, improved its designs and became the world's largest turbine manufacturer and wind farm developer before succumbing to the weight of aggressive development efforts, serious technical problems with its newest turbines, and a weak U.S. market, ultimately filing for bankruptcy in 1996.

Testing wall panels for earthquake response  

SciTech Connect

As part of the structural response research program being conducted for the Nevada Operations Office of ERDA a testing program for the investigation of nonstructural wall panels subjected to racking was developed and conducted. The objectives of the testing program were to determine thresholds for damage to partitions due to horizontal adjacent story displacement in high-rise buildings and to gather data that can be used to determine the influence of nonstructural partitions on the structural response of high-rise buildings. In general, the wall panels were constructed to represent typical partitions used in high-rise building construction. Some of the panels were used for special parameter studies or for comparisons with other test programs. A specially designed testing frame simulated cyclic lateral displacement, parallel to the plane of the wall panels, that might be experienced during the response of a building to strong winds or earthquake motion. Stiffness and strength characteristics, estimates of equivalent viscous damping, and damage threshold results were obtained. The data appear to give a good approximate evaluation of the performance of non-load-bearing partitions under cyclic loading. (LCL)

SMALL-VOLUME BASALTIC VOLCANOES: ERUPTIVE PRODUCTS AND PROCESSES, AND POST-ERUPTIVE GEOMORPHIC EVOLUTION IN CRATER FLAT (PLEISTOCENE), SOUTHERN NEVADA  

SciTech Connect

Five Pleistocene basaltic volcanoes in Crater Flat (southern Nevada) demonstrate the complexity of eruption processes associated with small-volume basalts and the effects of initial emplacement characteristics on post-eruptive geomorphic evolution of the volcanic surfaces. The volcanoes record eruptive processes in their pyroclastic facies ranging from ''classical'' Strombolian mechanisms to, potentially, violent Strombolian mechanisms. Cone growth was accompanied, and sometimes disrupted, by effusion of lavas from the bases of cones. Pyroclastic cones were built upon a gently southward-sloping surface and were prone to failure of their down-slope (southern) flanks. Early lavas flowed primarily southward and, at Red and Black Cone volcanoes, carried abundant rafts of cone material on the tops of the flows. These resulting early lava fields eventually built platforms such that later flows erupted from the eastern (at Red Cone) and northern (at Black Cone) bases of the cones. Three major surface features--scoria cones, lava fields with abundant rafts of pyroclastic material, and lava fields with little or no pyroclastic material--experienced different post-eruptive surficial processes. Contrary to previous interpretations, we argue that the Pleistocene Crater Flat volcanoes are monogenetic, each having formed in a single eruptive episode lasting months to a few years, and with all eruptive products having emanated from the area of the volcanoes main cones rather than from scattered vents. Geochemical variations within the volcanoes must be interpreted within a monogenetic framework, which implies preservation of magma source heterogeneities through ascent and eruption of the magmas.

Analysis of end-use electricity consumption during two Pacific Northwest cold snaps  

SciTech Connect

The Pacific Northwest has experienced unusually cold weather during two recent heating seasons. Hourly end-use load data was collected from a sample of residential and commercial buildings during both cold snaps. Earlier work documented the changes in end-use load shapes as outdoor temperature became colder. This paper extends analysis of cold snap load shapes by comparing results from both cold snaps, exploring the variability of electricity consumption between sites, and describing the use of load shapes in simulating system load. Load shapes from the first cold snap showed that hot water use shifted to later in the morning during extremely cold weather. This shift in load also occurred during the second cold snap and is similar to the shift observed on a typical weekend. Electricity consumption averaged across many sites can mask widely varying behavior at individual sites. For example, electricity consumption for space heat varies greatly between homes, especially when many homes are able to burn wood. Electricity consumption for space heat is compared between a group of energy-efficient homes and a group of older homes.

Monitoring and Evaluation of Supplemented Spring Chinook Salmon and Life Histories of Wild Summer Steelhead in the Grande Ronde Basin, 2007 Annual Report.  

DOE Green Energy (OSTI)

This is the ninth annual report for a multi-year project designed to monitor and evaluate supplementation of endemic spring Chinook salmon in Catherine Creek and the upper Grande Ronde River. These two streams historically supported anadromous fish populations that provided significant tribal and non-tribal fisheries, but in recent years, have experienced severe declines in abundance. Conventional and captive broodstock supplementation methods are being used to restore these spring Chinook salmon populations. Spring Chinook salmon populations in Catherine Creek and the upper Grande Ronde River, and other streams in the Snake River Basin have experienced severe declines in abundance over the past two decades (Nehlsen et al. 1991). A supplementation program was initiated in Catherine Creek and the upper Grande Ronde River, incorporating the use of both captive and conventional broodstock methods, in order to prevent extinction in the short term and eventually rebuild populations. The captive broodstock component of the program (BPA Project 199801001) uses natural-origin parr collected by seining and reared to maturity at facilities near Seattle, Washington (Manchester Marine Laboratory) and Hood River, Oregon (Bonneville Hatchery). Spawning occurs at Bonneville Hatchery, and resulting progeny are reared in hatcheries. Shortly before outmigration in the spring, juveniles are transferred to acclimation facilities. After an acclimation period of about 2-4 weeks, volitional release begins. Any juveniles remaining after the volitional release period are forced out. The conventional broodstock component uses returning adults collected at traps near the spawning areas, transported to Lookingglass Hatchery near Elgin, Oregon, held, and later spawned. The resulting progeny are reared, acclimated, and released similar to the captive broodstock component. All progeny released receive one or more marks including a fin (adipose) clip, codedwire tag, PIT tag, or visual implant elastomer tag. The numbers of adults used for conventional broodstock are determined by an agreement among comanagers (Zimmerman and Patterson 2002). Activities for this project focus on two life stages of spring Chinook salmon: juveniles during the migration from freshwater to the ocean and adults during prespawning migration through the end of spawning. Life history, production, and genetics are monitored and used to evaluate program effectiveness.

Three-body interactions on a triangular lattice  

Science Conference Proceedings (OSTI)

We analyze the hard-core Bose-Hubbard model with both three-body and nearest-neighbor repulsions on a triangular lattice. The phase diagram is achieved by means of the semiclassical approximation and a quantum Monte Carlo simulation. For a system with only three-body interactions, both the supersolid phase and the one-third solid disappear while the two-thirds solid is stable. As the thermal behavior of the bosons with nearest-neighbor repulsion, the solid and the superfluid undergo the three-state Potts- and Kosterlitz-Thouless-type phase transitions, respectively. In a system with both frustrated nearest-neighbor two-body and three-body interactions, the supersolid and one-third solid are revived. By tuning the strength of the three-body interactions, the phase diagram is distorted because the one-third solid and the supersolid are suppressed.

Beam optics in a MeV-class multi-aperture multi-grid accelerator for the ITER neutral beam injector  

SciTech Connect

In a multi-aperture multi-grid accelerator of the ITER neutral beam injector, the beamlets are deflected due to space charge repulsion between beamlets and beam groups, and also due to magnetic field. Moreover, the beamlet deflection is influenced by electric field distortion generated by grid support structure. Such complicated beamlet deflections and the compensations have been examined utilizing a three-dimensional beam analysis. The space charge repulsion and the influence by the grid support structure were studied in a 1/4 model of the accelerator including 320 beamlets. Beamlet deflection due to the magnetic field was studied by a single beamlet model. As the results, compensation methods of the beamlet deflection were designed, so as to utilize a metal bar (so-called field shaping plate) of 1 mm thick beneath the electron suppression grid (ESG), and an aperture offset of 1 mm in the ESG.

Self-Organized Hydrodynamics with congestion and path formation in crowds  

E-Print Network (OSTI)

A continuum model for self-organized dynamics is numerically investigated. The model describes systems of particles subject to alignment interaction and short-range repulsion. It consists of a non-conservative hyperbolic system for the density and velocity orientation. Short-range repulsion is included through a singular pressure which becomes infinite at the jamming density. The singular limit of infinite pressure stiffness leads to phase transitions from compressible to incompressible dynamics. The paper proposes an Asymptotic-Preserving scheme which takes care of the singular pressure while preventing the breakdown of the CFL stability condition near congestion. It relies on a relaxation approximation of the system and an elliptic formulation of the pressure equation. Numerical simulations of impinging clusters show the efficiency of the scheme to treat congestions. A two-fluid variant of the model provides a model of path formation in crowds.

Soliton trains in Bose-Fermi mixtures  

E-Print Network (OSTI)

We theoretically consider the formation of bright solitons in a mixture of Bose and Fermi degenerate gases. While we assume the forces between atoms in a pure Bose component to be effectively repulsive, their character can be changed from repulsive to attractive in the presence of fermions provided the Bose and Fermi gases attract each other strongly enough. In such a regime the Bose component becomes a gas of effectively attractive atoms. Hence, generating bright solitons in the bosonic gas is possible. Indeed, after a sudden increase of the strength of attraction between bosons and fermions (realized by using a Feshbach resonance technique or by firm radial squeezing of both samples) soliton trains appear in the Bose-Fermi mixture.

Abrupt grain boundary melting in ice  

E-Print Network (OSTI)

The effect of impurities on the grain boundary melting of ice is investigated through an extension of Derjaguin-Landau-Verwey-Overbeek theory, in which we include retarded potential effects in a calculation of the full frequency dependent van der Waals and Coulombic interactions within a grain boundary. At high dopant concentrations the classical solutal effect dominates the melting behavior. However, depending on the amount of impurity and the surface charge density, as temperature decreases, the attractive tail of the dispersion force interaction begins to compete effectively with the repulsive screened Coulomb interaction. This leads to a film-thickness/temperature curve that changes depending on the relative strengths of these interactions and exhibits a decrease in the film thickness with increasing impurity level. More striking is the fact that at very large film thicknesses, the repulsive Coulomb interaction can be effectively screened leading to an abrupt reduction to zero film thickness.

Renormalization group and the superconducting susceptibility of a Fermi liquid  

Science Conference Proceedings (OSTI)

A free Fermi gas has, famously, a superconducting susceptibility that diverges logarithmically at zero temperature. In this paper we ask whether this is still true for a Fermi liquid and find that the answer is that it does not. From the perspective of the renormalization group for interacting fermions, the question arises because a repulsive interaction in the Cooper channel is a marginally irrelevant operator at the Fermi liquid fixed point and thus is also expected to infect various physical quantities with logarithms. Somewhat surprisingly, at least from the renormalization group viewpoint, the result for the superconducting susceptibility is that two logarithms are not better than one. In the course of this investigation we derive a Callan-Symanzik equation for the repulsive Fermi liquid using the momentum-shell renormalization group, and use it to compute the long-wavelength behavior of the superconducting correlation function in the emergent low-energy theory. We expect this technique to be of broader interest.

A Large Blue Shift of the Biexciton State in Tellurium Doped CdSe Colloidal Quantum Dots  

E-Print Network (OSTI)

The exciton-exciton interaction energy of Tellurium doped CdSe colloidal quantum dots is experimentally investigated. The dots exhibit a strong Coulomb repulsion between the two excitons, which results in a huge measured biexciton blue shift of up to 300 meV. Such a strong Coulomb repulsion implies a very narrow hole wave function localized around the defect, which is manifested by a large Stokes shift. Moreover, we show that the biexciton blue shift increases linearly with the Stokes shift. This result is highly relevant for the use of colloidal QDs as optical gain media, where a large biexciton blue shift is required to obtain gain in the single exciton regime. The progress in chemical synthesis of colloidal quantum dots, provides a way to produce high quantum yield nanocrystals out of a variety of substances, and allows control over their size, shape and composition. Because of the strong charge confinement within the dots, their electronic excitation

Topological interactions between ring polymers: Implications for chromatin loops  

E-Print Network (OSTI)

Chromatin looping is a major epigenetic regulatory mechanism in higher eukaryotes. Besides its role in transcriptional regulation, chromatin loops have been proposed to play a pivotal role in the segregation of entire chromosomes. The detailed topological and entropic forces between loops still remain elusive. Here, we quantitatively determine the potential of mean force between the centers of mass of two ring polymers, i.e. loops. We find that the transition from a linear to a ring polymer induces a strong increase in the entropic repulsion between these two polymers. On top, topological interactions such as the non-catenation constraint further reduce the number of accessible conformations of close-by ring polymers by about 50%, resulting in an additional effective repulsion. Furthermore, the transition from linear to ring polymers displays changes in the conformational and structural properties of the system. In fact, ring polymers adopt a markedly more ordered and aligned state than linear ones. The force...

Dark matter, dark energy and gravitational proprieties of antimatter  

E-Print Network (OSTI)

We suggest that the eventual gravitational repulsion between matter and antimatter may be a key for understanding of the nature of dark matter and dark energy. If there is gravitational repulsion, virtual particle-antiparticle pairs in the vacuum, may be considered as gravitational dipoles. We use a simple toy model to reveal a first indication that the gravitational polarization of such a vacuum, caused by baryonic matter in a Galaxy, may produce the same effect as supposed existence of dark matter. In addition, we argue that cancellation of gravitational charges in virtual particle-antiparticle pairs, may be a basis for a solution of the cosmological constant problem and identification of dark energy with vacuum energy. Hence, it may be that dark matter and dark energy are not new, unknown forms of matter-energy but an effect of complex interaction between quantum vacuum and known baryonic matter.

Hysteresis and re-entrant melting of a self-organized system of classical particles confined in a parabolic trap  

E-Print Network (OSTI)

A self-organized system composed of classical particles confined in a two-dimensional parabolic trap and interacting through a potential with a short-range attractive part and long-range repulsive part is studied as function of temperature. The influence of the competition between the short-range attractive part of the inter-particle potential and its long-range repulsive part on the melting temperature is studied. Different behaviors of the melting temperature are found depending on the screening length ($\\kappa$) and the strength ($B$) of the attractive part of the inter-particle potential. A re-entrant behavior and a thermal induced phase transition is observed in a small region of ($\\kappa,B$)-space. A structural hysteresis effect is observed as a function of temperature and physically understood as due to the presence of a potential barrier between different configurations of the system.

The electric machine includes a shaft defining an axis of rotation, first and second magnets, a shielding portion, and a conductor. First and second magnets are coaxial with the shaft and include a charged pole surface and an oppositely charged pole surface, the charged pole surfaces facing one another to form a repulsive field therebetween. The shield portion extends between the magnets to confine at least a portion of the repulsive field to between the first and second magnets.

Theory Of Alkyl Terminated Silicon Quantum Dots  

DOE Green Energy (OSTI)

We have carried out a series of ab-initio calculations to investigate changes in the optical properties of Si quantum dots as a function of surface passivation. In particular, we have compared hydrogen passivated dots with those having alkyl groups at the surface. We find that, while on clusters with reconstructed surfaces a complete alkyl passivation is possible, steric repulsion prevents full passivation of Si dots with unreconstructed surfaces. In addition, our calculations show that steric repulsion may have a dominant effect in determining the surface structure, and eventually the stability of alkyl passivated clusters, with results dependent on the length of the carbon chain. Alkyl passivation weakly affects optical gaps of silicon quantum dots, while it substantially decreases ionization potentials and electron affinities and affect their excited state properties. On the basis of our results we propose that alkyl terminated quantum dots may be size selected taking advantage of the change in ionization potential as a function of the cluster size.

Casimir interactions between graphene sheets and metamaterials  

SciTech Connect

The Casimir force between graphene sheets and metamaterials is studied. Theoretical results based on the Lifshitz theory for layered, planar, two-dimensional systems in media are presented. We consider graphene-graphene, graphene-metamaterial, and metal-graphene-metamaterial configurations. We find that quantum effects of the temperature-dependent force are not apparent until the submicron range. In contrast to results with bulk dielectric and bulk metallic materials, no Casimir repulsion is found when graphene is placed on top of a magnetically active metamaterial substrate, regardless of the strength of the low-frequency magnetic response. In the case of the metal-graphene-metamaterial setting, repulsion between the metamaterial and the metal-graphene system is possible only when the dielectric response from the metal contributes significantly.

Lifetime of micrometer-sized drops of oil pressed by buoyancy against a planar interface  

E-Print Network (OSTI)

Emulsion Stability Simulations (ESS) are used to estimate the coalescence time of one drop of hexadecane pressed by buoyancy against a planar water/hexadecane interface. In the present simulations the homophase is represented by a big drop of oil at least 500 times larger than the approaching drop ($1\\,\\mu$m to $10\\,\\mu$m). Both deformable and non-deformable drops are considered along with six different diffusion tensors. In each case van der Waals, electrostatic, steric and buoyancy forces are taken into account. The coalescence times are estimated as the average of 1000 random walks. It is found that the repulsive potential barrier has a significant influence in the results. The experimental data can only be reproduced assuming negligible repulsive barriers, as well as non-deformable drops that move with a combination of Stokes and Taylor tensors as they approach the interface.

It is shown that the Coulomb superconducting pairing in systems with the Fermi contour nesting can be described by a quasi-one-dimensional potential oscillating in real space. The supplement of this repulsive potential with an isotropic pairing attraction corresponding to the phonon superconductivity mechanism and including the effect of predominant forward scattering upon electron-phonon interaction leads to symmetrization of this potential and a considerable increase in the superconducting transition temperature.

Motivated by a recent experiment at MIT, we consider the collision of two clouds of spin-polarized atomic Fermi gases close to a Feshbach resonance. We explain why two dilute gas clouds, with underlying attractive interactions between their constituents, bounce off each other in the strongly interacting regime. Our hydrodynamic analysis, in excellent agreement with experiment, gives strong evidence for a metastable many-body state with effective repulsive interactions.

Co-existence of Gravity and Antigravity: The Unification of Dark Matter and Dark Energy  

E-Print Network (OSTI)

Massive gravity with second and fourth derivatives is shown to give both attractive and repulsive gravities. In contrast to the attractive gravity correlated with the energy-momentum tensor, the repulsive gravity is related to a fixed mass $m_x$, which equals a spin-dependent factor $f_\\sigma$ times the graviton mass. Therefore, particles with energy below $m_x$ are both dark matter and dark energy: Their overall gravity is attractive with normal matter but repulsive among themselves. Detailed analyses reveal that this unified dark scenario can properly account for the observed dark matter/energy phenomena: galaxy rotation curves, transition from early cosmic deceleration to recent acceleration; and naturally overcome other dark scenarios' difficulties: the substructure and cuspy core problems, the difference of dark halo distributions in galaxies and clusters, and the cosmic coincidence. Very interestingly, Dirac particles have $f_\\sigma=1/\\sqrt 2$, all bosonic matter particles have $f_\\sigma=0$, and the only exceptional boson is the graviton itself, which may have $f_\\sigma>1$.

Adsorption potential of alkanes on graphite  

SciTech Connect

In the framework of the extended Hueckel theory, the short-range repulsive interaction of alkanes with graphite is determined with band structure calculations from the difference between the total energy of the system (adsorbate + graphite) and the energy of the separated species. This theoretical approach enables one to determine the coefficients of the repulsive exponential term in the atom-atom potential simplified expression. The adsorption potential of alkanes on graphite is obtained when the dispersion atom-atom potential, which takes into account the high anisotropic polarizability of graphite, is added to the repulsive term. The equilibrium distance of methane on graphite and its vibrational frequency perpendicular to the surface are in good agreement with the experimental ones measured at low temperatures by neutron scattering techniques. The van der Waals radii of carbon and hydrogen atoms are obtained from the equilibrium distance of the atom-atom potential simplified expression. They are compared with those used in the literature to establish the semiempirical potential expressions. The molecular statistical theory of adsorption based on the atom-atom potential function enables one to predict the second adsorbate/surface virial coefficient and the thermodynamic characteristics of adsorption, measured for methane, ethane, and propane on graphitized carbon black at zero surface coverage by static and gas chromatographic methods.

Direct measurements of the effects of salt and surfactant on interaction forces between colloidal particles at water-oil interfaces  

E-Print Network (OSTI)

The forces between colloidal particles at a decane-water interface, in the presence of low concentrations of a monovalent salt (NaCl) and of the surfactant sodium dodecylsulfate (SDS) in the aqueous subphase, have been studied using laser tweezers. In the absence of electrolyte and surfactant, particle interactions exhibit a long-range repulsion, yet the variation of the interaction for different particle pairs is found to be considerable. Averaging over several particle pairs was hence found to be necessary to obtain reliable assessment of the effects of salt and surfactant. It has previously been suggested that the repulsion is consistent with electrostatic interactions between a small number of dissociated charges in the oil phase, leading to a decay with distance to the power -4 and an absence of any effect of electrolyte concentration. However, the present work demonstrates that increasing the electrolyte concentration does yield, on average, a reduction of the magnitude of the interaction force with electrolyte concentration. This implies that charges on the water side also contribute significantly to the electrostatic interactions. An increase in the concentration of SDS leads to a similar decrease of the interaction force. Moreover the repulsion at fixed SDS concentrations decreases over longer times. Finally, measurements of three-body interactions provide insight into the anisotropic nature of the interactions. The unique time-dependent and anisotropic interactions between particles at the oil-water interface allow tailoring of the aggregation kinetics and structure of the suspension structure.

Coulomb-tail effect of electron-electron interaction on nonsequential double ionization  

Science Conference Proceedings (OSTI)

With the classical ensemble model, we investigate the manifestations of the Coulomb tail of electron-electron interaction in nonsequential double ionization by comparing the results from the short-range electron-electron interaction with those from the Coulombic electron-electron interaction. At the intensity below the recollision threshold, the two-electron momentum distributions in the direction parallel to the laser polarization show an anticorrelated behavior for the Coulombic electron-electron interaction while a correlated behavior for the short-range interaction, which indicates the responsibility of the Coulomb tail of the electron-electron interaction for the experimentally observed anticorrelated emission [Y. Liu, S. Tschuch, A. Rudenko, M. Durr, M. Siegel, U. Morgner, R. Moshammer, and J. Ullrich, Phys. Rev. Lett. 101, 053001 (2008)]. In the transverse direction, for the Coulombic electron-electron interaction, the two electrons exhibit no effect of repulsion at an intensity below the recollision threshold while a strong repulsion effect at an intensity above the threshold, which becomes weaker as the laser intensity further increases. Back analysis shows that the role of the Coulomb tail of electron-electron interaction leads asymmetric energy sharing (AES) to be prevalent at recollision. This AES results in the two electrons leaving the ion at different times or with different initial momenta, which is responsible for the anticorrelated behavior in the parallel direction and the intensity-dependent repulsion effect in the transverse direction.

17048 Biochemistry 1998, 37, 17048-17053 Sugar-Induced Molten-Globule Model †  

E-Print Network (OSTI)

ABSTRACT: Proteins denature at low pH because of intramolecular electrostatic repulsions. The addition of salt partially overcomes this repulsion for some proteins, yielding a collapsed conformation called the A-state. A-states have characteristics expected for the molten globule, a notional kinetic protein folding intermediate. Here we show that the addition of neutral sugars to solutions of acid-denatured equine ferricytochrome c induces formation of the A-state in the absence of added salt. We characterized the structure and stability of the sugar-induced A-state with circular dichroism spectropolarimetry (CD) and NMR-monitored hydrogen-deuterium exchange experiments. We also examined the stability of the sugarinduced A-state as a function of sugar size and concentration. The results are interpreted using several models and we conclude that the stabilizing effect is consistent with increased steric repulsion between the protein and the sugar solutions. Structural and stability studies of molten globule-like states have been instrumental in expanding our knowledge of protein folding. Molten globules, notional kinetic folding intermediates, are compact and possess nativelike secondary structure and some native tertiary contacts (1-3). An

Argonne V18 Pair Interaction Plus Modern Versions of Urbana or Illinois Three-Body Forces Make Neutron Matter Unstable  

E-Print Network (OSTI)

It is shown that the neutron matter interacting through Argonne V18 pair-potential plus modern variants of Urbana or Illinois three-body forces is unstable. For the energy of $N$ neutrons E(N), which interact through these forces, we prove mathematically that $E(N) = -cN^3 + \\mathcal{O}(N^{8/3})$, where $c>0$ is a constant. This means that: (i) the energy per particle and neutron density diverge rapidly for large neutron numbers; (ii) bound states of $N$ neutrons exist for $N$ large enough. The neutron matter collapse is possible due to the form of the repulsive core in three-body forces, which vanishes when three nucleons occupy the same site in space. The old variant of the forces Urbana VI, where the phenomenological repulsive core does not vanish at the origin, resolves this problem. The obtained results partly change the paradigm, in which the stability of neutron stars is attained through the Pauli principle; the strong repulsive core in the nucleon interactions is by no means less important.

Toward Understanding the Nature of Internal Rotation Barriers with a New Energy Partition Scheme: Ethane and n-Butane  

Science Conference Proceedings (OSTI)

Based on an alternative energy partition scheme where density-based quantification of the steric effect was proposed [S.B. Liu, J. Chem. Phys. 126, 244103 (2007)], the origin of the internal rotation barrier between the eclipsed and staggered conformers of ethane and n-butane is systematically investigated in this work. The new definition is repulsive, exclusive, and extensive, and is intrinsically related to Bader’s atoms in molecules approach. Two kinds of differences, adiabatic (with optimal structure) and vertical (with fixed geometry), are considered in this work. We find that in the adiabatic case the eclipsed conformer possesses a larger steric repulsion than the staggered conformer for both molecules, but in the vertical cases the staggered conformer retains a larger steric repulsion. For ethane, a strong correlation between the total energy difference and the fermionic quantum energy difference is discovered. This linear relationship, however, does not hold for n-butane, whose behaviors in energy component differences are found to be more complicated. The impact of basis set and density functional choices on energy components from the new energy partition scheme has been investigated, as has its comparison with another definition of the steric effect in the literature in terms of the natural bond orbital analysis through the Pauli Exclusion Principle. Profiles of conceptual DFT reactivity indices as a function of dihedral angle changes have also been examined. Put together, these results suggest that the new energy partition scheme provides insights from a different perspective of internal rotation barriers.

Coupled-channels calculations of $^{16}$O+$^{16}$O fusion  

E-Print Network (OSTI)

Fusion data for $^{16}$O+$^{16}$O are analyzed by coupled-channels calculations. It is shown that the calculated cross sections are sensitive to the couplings to the $2^+$ and $3^-$ excitation channels even at low energies, where these channels are closed. The sensitivity to the ion-ion potential is investigated by applying a conventional Woods-Saxon potential and the M3Y+repulsion potential, consisting of the M3Y double-folding potential and a repulsive term that simulates the effect of the nuclear incompressibility. The best overall fit to the data is obtained with a M3Y+repulsion potential which produces a shallow potential in the entrance channel. The stepwise increase in measured fusion cross sections at high energies is also consistent with such a shallow potential. The steps are correlated with overcoming the barriers for the angular momenta $L$ = 12, 14, 16, and 18. To improve the fit to the low-energy data requires a shallower potential and this causes a even stronger hindrance of fusion at low energies. It is therefore difficult, based on the existing fusion data, to make an accurate extrapolation to energies that are of interest to astrophysics.

Spatial and Temporal Dynamics of Salt Marsh Vegetation across Scales  

E-Print Network (OSTI)

Biogeographic patterns across a landscape are developed by the interplay of environmental processes operating at different spatial and temporal scales. This research investigated dynamics of salt marsh vegetation on the Skallingen salt marsh in Denmark responding to environmental variations at large, medium, and fine scales along both spatial and temporal spectrums. At the broad scale, this research addressed the importance of wind-induced rise of the sea surface in such biogeographic changes. A new hypothetical chain was suggested: recent trends in the North Atlantic Oscillation index toward its positive phase have led to increased storminess and wind tides on the ocean surface, resulting in increased frequency, duration, and magnitude of submergence and, hence, waterlogging of marsh soils and plants, which has retarded ecological succession. At the mid-scale, spatial patterns of vegetation and environmental factors were examined across tidal creeks. Sites closer to tidal creeks, compared to marsh interiors, were characterized by the dominance of later-successional species, higher bulk density, and lower nutrient contents and electrical conductivity. This finding implies that locations near creeks have experienced a better drainage condition than the inner marshes, which eventually facilitated the establishment of later-successional plants that are intolerant to physical stress. At the micro-scale, this research examined how the extent and mode of facilitation and competition vary for different combinations of plant species along physical gradients. Both positive and negative relationships were spatially manifested to a greater degree on the low marsh than on the mid marsh. This insight extends our current knowledge of scale-dependent interactions beyond pioneer zones to higher zones. On the low marsh, different types of bivariate point pattern (i.e., clustered, random, and regular) were observed for different combinations of species even at similar spatial scales. This finding implies that it is difficult to generalize at which scales competition and facilitation occur. To conclude, this research stresses the need for a holistic approach in future investigations of salt marsh biogeography. For example, based on results of this current research, it would be meaningful to develop a comprehensive simulation model that incorporates salt marsh ecology, geomorphology, and hydrology observed across scales.

Multi Canister Overpack (MCO) Handling Machine Trolley Seismic Uplift Constraint Design Loads  

Science Conference Proceedings (OSTI)

The MCO Handling Machine (MHM) trolley moves along the top of the MHM bridge girders on east-west oriented rails. To prevent trolley wheel uplift during a seismic event, passive uplift constraints are provided as shown in Figure 1-1. North-south trolley wheel movement is prevented by flanges on the trolley wheels. When the MHM is positioned over a Multi-Canister Overpack (MCO) storage tube, east-west seismic restraints are activated to prevent trolley movement during MCO handling. The active seismic constraints consist of a plunger, which is inserted into slots positioned along the tracks as shown in Figure 1-1. When the MHM trolley is moving between storage tube positions, the active seismic restraints are not engaged. The MHM has been designed and analyzed in accordance with ASME NOG-1-1995. The ALSTHOM seismic analysis (Reference 3) reported seismic uplift restraint loading and EDERER performed corresponding structural calculations. The ALSTHOM and EDERER calculations were performed with the east-west seismic restraints activated and the uplift restraints experiencing only vertical loading. In support of development of the CSB Safety Analysis Report (SAR), an evaluation of the MHM seismic response was requested for the case where the east-west trolley restraints are not engaged. For this case, the associated trolley movements would result in east-west lateral loads on the uplift constraints due to friction, as shown in Figure 1-2. During preliminary evaluations, questions were raised as to whether the EDERER calculations considered the latest ALSTHOM seismic analysis loads (See NCR No. 00-SNFP-0008, Reference 5). Further evaluation led to the conclusion that the EDERER calculations used appropriate vertical loading, but the uplift restraints would need to be re-analyzed and modified to account for lateral loading. The disposition of NCR 00-SNFP-0008 will track the redesign and modification effort. The purpose of this calculation is to establish bounding seismic loads (vertical and horizontal) for input into the uplift restraint hardware redesign calculations. To minimize iterations on the uplift redesign effort, efforts were made to assure that the final loading input was reasonable but unquestionably on the conservative side.

Tectonic framework of Crater Flat basin, adjacent to Yucca Mountain, Nevada: A preliminary report  

SciTech Connect

Detailed mapping of 9.5--14 Ma volcanic rocks in Crater Flat (CF) and vicinity is being used to test alternative tectonic models which form a basis for seismic risk assessments for a potential nuclear waste repository at Yucca Mountain. Preliminary results are: (1) the southern margin of the basin is a NW-trending right-oblique-slip fault; (2) two down-to-the-east normal faults form the western boundary of the basin against 2 different structural domains, a little-extended uplift called Bare Mountain to the south, and the much-extended Fluorspar Hills (FH) to the north. These two domains are separated by the roughly E-trending, left-oblique-slip Fluorspar Canyon fault; (3) Crater Flat basin actually is separated from the Fluorspar Hills by a narrow septum, the Tram Ridge horst (TR), which was a localized site of nondeposition from 11.5--13.1 Ma, and which experienced only minor extension during the peak periods of extension, at 12 and < 11 Ma, in Crater Flat and the Fluorspar Hills, respectively; (4) normal faults within Crater Flat are radial to, and largely decrease in throw northward toward the Timber Mountain caldera complex, which appears to have acted as a pivot point during opening of the basin; (5) increased faulting and tilting of strata with age reflects intermittent tectonism in Crater Flat throughout the volcanic period. The data also suggest a change in least principal stress direction from NNW before 13.1 Ma to WNW after. In combination, these results indicate that Crater Flat basin formed by simultaneous E-W extension and NW-directed right-lateral shear; it could be described as a half-rhombochasm. To date, the authors find no support for a model that explains the basin as a buried caldera. Future mapping is planned to test the differing predictions of strike-slip (Walker Lane) and detachment-fault models.

Internal structure of the Kern Canyon Fault, California: a deeply exhumed strike-slip fault  

E-Print Network (OSTI)

Deformation and mineral alteration adjacent to a 2 km long segment of the Kern Canyon fault near Lake Isabella, California are studied to characterize the internal structure of the fault zone and to understand the development of fault structure and constitution and the mechanical and chemical processes responsible for them. The 140 km long Kern Canyon fault (KCF) is a fault of 15 km right-lateral separation exhumed from seismogenic depth that cuts batholithic and metamorphic rocks of the southern Sierra Nevada. The fault consists of at least three distinct phases: an early phase of lower-greenschist-grade ductile shear with an S-C' phyllonite, a subsequent, dominant phase of brittle faulting characterized by a through-going zone of cataclastic rock, and a late stage of minor faulting along discontinuous, thin, hematitic gouge zones. The S-C' fabric and subsidiary fault-slip data indicate that both the phyllonitic and cataclastic zones are approximately vertical and strike-slip; slip lineations within the hematitic gouge suggest oblique-slip. The phyllonite zone trends N20-40E and accommodated ~175 m of separation. The cataclastic zone cuts the phyllonite, trends N21E, and consists of foliated and non-foliated cataclasites; it accommodates the majority of displacement along the fault. Abundant veins and fluid-assisted alteration in the rock surrounding the fault zone attest to the presence of fluids of evolving chemistry during both ductile and brittle faulting. Mass balance calculations indicate quartz loss during phyllonite faulting and imply that the fault system was open and experienced a negative change in volume during phyllonite faulting. Mesoscale and microscale fracture intensities decrease with log distance from the foliated cataclasites and approach a relatively low level at approximately 500 m. The internal structure of the Kern Canyon fault is similar to other large displacement faults in that it consists of a broad zone of fractured and altered rock and a narrow zone of intense cataclasis.

A Gold Bubble?  

E-Print Network (OSTI)

Financial bubbles make good entertainment. One often reads speculation that a certain stock, commodity, or even housing is in the midst of a price bubble. For stocks, examples often come from initial public offerings (IPOs), the most recent being LinkedIn (see for example [3]), and a large collection of such occurred during the dot com mania around the turn of the century. Part of the problem in deciding whether an asset is experiencing a price bubble is that there is not a widespread understanding of what a bubble actually is, although there is plenty of expressed desire to detect one in real time. Indeed, the President of the Federal Reserve, Ben Bernanke, said during his confirmation hearings in 2009, “It is extraordinarily difficult in real time to know if an asset price is appropriate or not”[1] Commodities are also great examples of alleged price bubbles. A famous example was the oil price increases of 2007/2008. Nobel prize winning economist Paul Krugman wrote in the New York Times that oil prices were not a bubble, and two days later Ben Stein wrote in the same paper that they were. Without a quantitative procedure, experts often have different opinions about the existence of price bubbles. In this regard William Dudley, the President of the New York Federal Reserve, in an interview with Planet Money stated “...what I am proposing is that we try to identify bubbles in real time, try to develop tools to address those bubbles, try to use those tools when appropriate to limit the size of those bubbles and, therefore, try to limit the damage when those bubbles burst. ” [5

Uranium potential of southwestern New Mexico (southern Hidalgo County), including observations on crystallization history of lavas and ash tuffs and the release of uranium from them. Final report  

SciTech Connect

Geological environments present in southwestern New Mexico include thick sequences of sedimentary rock including limestone, conglomerates, sandstone, and shale: igneous intrusions with associated metal deposits; caldera centers, margins, and outflow facies; and basins with marginal faults and thick late Cenozoic sedimentary fillings. Predominant rock types are Paleozoic carbonates, Mesozoic terrigeneous rocks and carbonates, and Cenozoic volcanic rocks and basin-filling terrigeneous rocks. Consideration of information available in Preliminary Reconnaissance Reports and in Hydrogeochemical and Stream Reconnaissance Reports together with 347 new whole rock chemical analyses points to three areas of anomalous uranium abundance in Hidalgo County, New Mexico. The area has experienced three major periods of igneous activity in Phanerozoic time: one associated with the Laramide cycle of the Late Cretaceous and early Tertiary, mid-Tertiary cycle of silicic volcanism with abundant calderas, and a late Tertiary cycle of mafic volcanism. Silicic volcanic rocks are the most common exposed rock type in the area, and the most enriched in uranium (range, 0.4 to 19 ppM). The most likely source for any uranium ore-forming solutions lies with this cycle of volcanism. Solutions might have been introduced during volcanism or formed later by groundwater leaching of cooled volcanic rocks. Results indicate that groundwater leaching of cooled volcanic rocks was not an effective means of mobilizing uranium in the area. Study of several rhyolite lava flows indicates that they were emplaced in supercooled condition and may have crystallized completely at temperatures well below their liquids, or they may have warmed as crystallization released latent heat. Statistical comparison of the uranium concentration revealed no differences between vitrophyres and associated felsites.

Rejuvenation of spiral bulges  

E-Print Network (OSTI)

We seek to understand whether the stellar populations of galactic bulges show fingerprints of secular evolution triggered by the presence of the disc. For this purpose we re-analyse the sample of Proctor and Sansom, deriving stellar population ages and element abundances from absorption line indices. We obtain very consistent constraints on ages from the three Balmer indices Hbeta, Hgamma, and Hdelta, in good agreement with those of Proctor and Sansom based on a completely different method. Like other studies in the literature, we find that bulges have relatively low luminosity weighted ages, the lowest age derived for the smallest bulges being 1.3 Gyr. Hence bulges are not generally old but actually rejuvenated systems. We discuss evidence that this might be true also for the bulge of the Milky Way. We show that the smallest bulges, being the youngest with the lowest alpha/Fe ratios, must have experienced star formation events involving 10-30 per cent of their total mass in the past 1-2 Gyr. No significant correlations of the stellar population parameters with Hubble Type are found instead. We show that the relationships with sigma coincide perfectly with those of early-type galaxies. Hence, bulges are typically seen younger, metal-poorer and less alpha/Fe enhanced than early-type galaxies, only because of their smaller masses. At a given velocity dispersion, bulges and elliptical galaxies are indistinguishable as far as their stellar populations are concerned. These results favour an inside-out formation scenario and indicate that the discs in spiral galaxies of Hubble types Sbc and earlier cannot have a significant influence on the evolution of the stellar populations in the bulge component. The phenomenon of pseudobulge formation must be restricted to spirals of types later than Sbc.
