Parameter consistency in multienergetic k?p models  

Science Journals Connector (OSTI)

Standard derivations of multiband k?p models rely on Lwdin perturbation theory. Close examination of this method, however, reveals that it is unsuitable for treating systems with multiple zeroth-order energies. As a result, various perturbation sums in multienergetic k?p models are not well defined, and a consistent set of k?p parameters cannot be guaranteed. We inspect this difficulty and present an alternative derivation of the k?p theory based on the method of infinitesimal basis transformations. This approach clearly demonstrates that a consistent k?p matrix can be generated from an arbitrary number of zeroth-order wave functions regardless of their energies. In addition, we obtain a corrected expression for off-diagonal perturbation sums. The expression is applied to give the corrected form for the asymmetric B parameter in the s-p-coupled zinc-blende k?p Hamiltonian.

Incorporation of incompleteness in the k?p perturbation theory  

Science Journals Connector (OSTI)

The k?p perturbation expansion for the energy of a nondegenerate band, familiar from solid-state texts, provides a convenient method for calculating the effective mass of the band in terms of the eigenstates of the system. As such, it would seem particularly useful in fitting the parameters of an empirical tight-binding model. Unfortunately, this expression is incorrect when applied to a model having an incomplete basis. We find that the correct expression may be derived from the usual result if the incompleteness of the basis is properly taken into account. In addition, since degenerate bands are often of interest, we discuss the correct calculation of their curvatures.

k?p theory of the Franz-Keldysh effect  

Science Journals Connector (OSTI)

We use the k?p formalism to calculate Franz-Keldysh (FK) absorption spectra in direct-band-gap III-V semiconductors. This method allows us to include band anisotropy and nonparabolicity as well as band mixing. With k?p models of various complexity, we investigate how these phenomena influence the main features of the electroabsorption using GaAs as an example. We show that the dependence of the FK absorption on the polarization of the incoming light can be understood in analogy to quasi-two-dimensional systems by mostly decoupled heavy- and light-hole bands involving the anisotropy of the bulk-momentum matrix elements. On the other hand, the FK absorption tail and the periods of the FK oscillations are mainly determined by the realistic energy dispersions of the bands. We discuss the applicability and the limits of simplified models and demonstrate that for most cases the field-induced interband mixing is negligible in comparison with the zero-field coupling of the bands. As an application, we show the consequences for the widely used method to determine the electric field from the FK oscillation periods measured by absorption or photoreflectance experiments. Most of the basic features have been observed in experiments. The qualitative details are of general validity.

Successes and failures of the k?p method: A direct assessment for GaAs/AlAs quantum structures  

Science Journals Connector (OSTI)

The k?p method combined with the envelope-function approximation is the tool most commonly used to predict electronic properties of semiconductor quantum wells and superlattices. We test this approach by comparing band energies, dispersion, and wave functions for GaAs/AlAs superlattices and quantum wells as computed directly from a pseudopotential band structure and using eight-band k?p. To assure equivalent inputs, all parameters needed for the k?p treatment are extracted from calculated bulk GaAs and AlAs pseudopotential band structures. Except for large exchange splittings in the in-plane dispersion for thin superlattices, present in pseudopotential calculations but absent from the k?p results, we find generally good agreement for heterostructure hole bands within ?200 meV of the GaAs valence-band maximum. There are systematic errors in band energies and dispersion for deeper hole bands (all other than hh1 and lh1) and significant qualitative and quantitative errors for the conduction bands. Errors for heterostructure conduction states which are derived from the zinc-blende ? point diminish as length scales increase beyond ?20 ML, while significant errors persist for L- and X-derived states.For bulk GaAs and AlAs, eight-band k?p bands agree well with pseudopotential results very near the zinc-blende ? point (where k?p parameters are fit) but the first GaAs X point conduction band is ?26 eV too high with respect to the pseudopotential result. We show that this inadequate description of the bulk band dispersion is the principal source of k?p errors in these heterostructures. A wave-function projection analysis shows that k?p errors for heterostructures simply reflect corresponding errors for the bulk constituents, weighted by the amount that such bulk states participate in heterostructure states. 1996 The American Physical Society.

Efficient, numerically stable multiband k?p treatment of quantum transport in semiconductor heterostructures  

Science Journals Connector (OSTI)

We present a method for treating quantum transport in heterostructures using multiband k?p theory. The method is similar to the multiband quantum transmitting boundary method developed earlier for use with multiband tight-binding band structure models, being efficient, numerically stable, and easy to implement. It also has the advantages of being intuitive to use and easy to generalize to include magnetic field and strain effects. We have applied this method to hole tunneling in prototypical p-type GaAs/AlAs double-barrier structure. 1996 The American Physical Society.

Transition-matrix elements for superlattices consisting of materials with the zinc-blende structure are presented in analytical form in the k?p approximation including the ?6, ?7, and ?8 bands. The resulting selection rules for cases where the magnetic field is absent, and where the magnetic field is applied perpendicular to the superlattice layers, are discussed. The results can be used for type-I, -II, and -III superlattices. They can also be used for other systems, such as a single quantum well.

Pseudopotential-based multiband k?p method for ?250 000-atom nanostructure systems  

Science Journals Connector (OSTI)

The electronic structure of quantum wells, wires, and dots is conventionally described by the envelope-function eight-band k?p method (the standard k?p model) whereby coupling with bands other than the highest valence and lowest conduction bands is neglected. There is now accumulated evidence that coupling with other bands and a correct description of far-from-? bulk states is crucial for quantitative modeling of nanostructure. While multiband generalization of the k?p exists for bulk solids, such approaches for nanostructures are rare. Starting with a pseudopotential plane-wave representation, we develop an efficient method for electronic-structure calculations of nanostructures in which (i) multiband coupling is included throughout the Brillouin zone and (ii) the underlying bulk band structure is described correctly even for far-from-? states. A previously neglected interband overlap matrix now appears in the k?p formalism, permitting correct intervalley couplings. The method can be applied either using self-consistent potentials taken from ab initio calculations on prototype small systems or from the empirical pseudopotential method. Application to both short- and long-period (GaAs)p/(AlAs)p superlattices (SL) recovers (i) the bending down (deconfinement) of the ?(?) energy level of (001) SL at small periods p; (ii) the type-IItype-I crossover at p?8 SL, and (iii) the even-odd oscillation of the energies of the R/X(L) state of (001) SL and ?(L) state of (111) SL. Introducing a few justified approximations, this method can be used to calculate the eigenstates of physical interest for large nanostructures. Application to spherical GaAs quantum dots embedded in an AlAs barrier (with ?250 000 atoms) shows a type-IItype-I crossover for a dot diameter of 70 , with an almost zero ?-X repulsion at the crossing point. Such a calculation takes less than 30 min on an IBM/6000 workstation model 590. 1996 The American Physical Society.

Multiplicity and asymmetric fireballs from ?+p, K+p, ?p, e-p, and ?-p reactions

Negative-pion multiplicities ?n-? produced by asymmetric fireballs are investigated in terms of the fireball mass M*, related to the Feynman-Yang scaling. Assuming ?n-??M* and making use of results of the previous analysis on pp and pp data, it is found that only one parameter is needed for both ?+p and K+p reactions and another one for ?p, e-p, and ?-p reactions. An attempt is made to analyze ? production by e+e- in analogy with the analysis of pp annihilation in a previous work.

The electronic structure of semiconducting diamond is calculated by the scalar-relativistic linear muffin-tin-orbital method within the local-density approximation. Information about matrix elements, effective masses, and Luttinger parameters is extracted by comparison with k?p calculations. An extended 1616 k?p calculation is performed using the parameters above as input so as to obtain the detailed band structure of the higher valence and lower conduction band states around the ? point in the (110) direction.

Gauge properties of k?p Hamiltonians for crystals with linear topological defects  

Science Journals Connector (OSTI)

A general expression for the k?p Hamiltonian in crystals with linear topological defects such as dislocations, disclinations, and dispirations has been found. It has been shown to contain gauge potential terms corresponding to a non-Abelian gauge group, E(3), which is the proper Euclidean group. The gauge field is confined within the cores of topological defects and influences the carriers in the bulk of the crystal through the gauge potential which extends beyond it. A general expression for the gauge potential A(r) is presented. For a crystal that contains only dislocations the gauge group E(3) degenerates into T(3), the Abelian subgroup of translations. The corresponding gauge potential becomes A^(r)=i?T(r)(p^/?-k?), where k? is the electron wave vector related to the point in the Brillouin zone for which the k?p Hamiltonian is written, p^ is the momentum-operator matrix in the basis of Bloch functions corresponding to k?, and ?(r) is the distortion tensor.

Rational differential systems, loop equations, and application to the q-th reductions of KP  

E-Print Network (OSTI)

To any solution of a linear system of differential equations, we associate a kernel, correlators satisfying a set of loop equations, and in presence of isomonodromic parameters, a Tau function. We then study their semiclassical expansion (WKB type expansion in powers of the weight hbar per derivative) of these quantities. When this expansion is of topological type (TT), the coefficients of expansions are computed by the topological recursion with initial data given by the semiclassical spectral curve of the linear system. This provides an efficient algorithm to compute them at least when the semiclassical spectral curve is of genus 0. TT is a non trivial property, and it is an open problem to find a criterion which guarantees it is satisfied. We prove TT and illustrate our construction for the linear systems associated to the q-th reductions of KP - which contain the (p,q) models as a specialization.

Modeling of electroabsorption in semiconductor quantum structures within the eight-band k?p theory  

Science Journals Connector (OSTI)

We have incorporated electric fields into the eight-band k?p theory, which we have applied to heterostructures, in conjunction with the envelope-function approximation. We use the method of Baraff and Gershoni to implement the electric-field effects in a computer program that calculates the optical properties of direct-band-gap heterostructures in one, two, and three dimensions. Using this method, we calculate the interband and intersubband electroabsorption of multiple quantum wells as well as the interband electroabsorption in superlattices. We illustrate the evolution of the Stark localization of the electron wave function under the application of an external electric field in superlattices. Comparison with experimental data, available in the literature, exhibits very good agreement between theory and experiment, with respect to the spectral shape, the absolute magnitude, and the electric-field dependence of the absorption.

General k?p theory of lattice-matched semiconductor heterostructures  

Science Journals Connector (OSTI)

A 12-mode heterostructure theory employing an eight-band zone-center k?p model is formulated on a level comparable to the envelope-function approximation. The theory implements probability-flux-conserving interface boundary conditions, but also accounts for the often neglected material dependence of the zone-center Bloch functions. Such material differences lead to a coupling of the light- and heavy-particle states which is absent in many other schemes. Further, we find previously unidentified contributions to the eight-band-model transfer matrix, one describing the effect of spin-orbit coupling on interfacial scattering, another providing corrections required by the use of the finite eight-band bases. An important consequence of the theory is a unique perspective that exposes the relationship among, and implicit assumptions involved in, various schemes appearing in the literature. In particular, the usual envelope-function approximation results from adding simplifying assumptions to the theory.

Modeling of strained quantum wires using eight-band k?p theory  

Science Journals Connector (OSTI)

We have calculated numerically the one-dimensional band structure and densities of states of a V-shaped In0.2Ga0.8As/AlxGa1-xAs single quantum wire using eight-band k?p theory. A finite-difference scheme is used for the calculations. The model includes the realistic orientation, shape, material composition, strain distribution, and piezoelectric charging of the wire. We find a dominant impact of the piezoelectric potential on the band structure and a marked spin splitting of the valence bands. Also, the conduction band is strongly nonparabolic. We propose an efficient procedure to calculate interior eigenvectors from Hamiltonians including conduction-bandvalence-band interactions. This algorithm is 2090 times faster than the best prevailing method and also applies to other Hamiltonians for the modeling of nanostructures, including those occurring in tight-binding or pseudopotential theory.

Analytical technique for extracting the eigenvalues of the k?p matrix that represents the band structure of semiconductors

By introducing the perturbation method for solving nonlinear equations into the band-structure calculations, we manage to extract an analytical expansion for all the roots of the seventh-order secular equation of the k?p matrix that represents the band structure of germanium in terms of the wave vector k in the [100] direction. The technique that we introduce is general and can be applied to any similar physical or mathematical situation.

Eight-band k?p model of strained zinc-blende crystals  

Science Journals Connector (OSTI)

Second-order Lwdin perturbation theory is used to calculate the interaction matrices for an eight-band k?p model (near the ? point) of zinc-blende crystals under a uniform strain. The model treats the ?6 conduction bands, ?8 valence bands, and ?7 spin-orbit split-off bands. The model includes strain interactions arising from both the orbital and spin-orbit terms of the Hamiltonian. In addition to the usual Pikus-Bir deformation-potential constants, a, b, and d, which describe the coupling of the valence band to strain, two new deformation-potential constants arise, a and b, which describe the coupling of the conduction band to strain. The constant a couples the conduction band to hydrostatic deformations and the constant b, which results from a lack of inversion symmetry, couples the conduction band to shear deformations. The strain also introduces a k-dependent conduction-bandvalence-band mixing that is linear in strain, in wave vector, and in the momentum matrix element between the conduction and valence bands. In the absence of strain, the eight-band Kane model is recovered. Under a finite strain, in the limit of a large conduction-bandvalence-band gap and large spin-orbit splitting, the four-band Luttinger model with strain is recovered.

Generalization of the k?p approach for strained layered semiconductor structures grown on high-index-planes  

Science Journals Connector (OSTI)

We present a generalized theoretical description of the 88 k?p approach for determining the band structure of layered semiconductor structures for any growth direction, including strain and piezoelectric effects. The definition of heavy, light, and splitoff hole states is extended to arbitrary growth directions in analogy to the conventional (001) case, by choosing an adapted set of basis functions. The choice of this basis allows a qualitative understanding of the in-plane band structure and of the optical properties of strained and unstrained structures. Besides, we solve the k?p Hamiltonian by means of an efficient real-space method allowing us to deal with arbitrary confining potentials. The theory is applied to unstrained, compressively strained, and tensilely strained quantum wells. We find that confinement energies, warping, and in-plane effective masses strongly depend on the direction of confinement and on strain. Piezoelectric effects further affect the dispersion for all growth directions other than (001) and (011). We also find that the optical transition strength depends on the in-plane light polarization for growth directions other than (001) and (111). 1996 The American Physical Society.

k?p theory of energy bands, wave functions, and optical selection rules in strained tetrahedral semiconductors  

Science Journals Connector (OSTI)

This paper examines an eight-band k?p theory of strained semiconductors yielding energy bands, wave functions, and momentum matrices. Only if the symmetry of the strained crystal is accounted for in all terms of the Hamiltonian, a consistent definition and calculation of the momentum matrix becomes possible. The band structure and wave functions are nonanalytical functions of strain and crystal momentum. For strained crystals, the extrapolation from the ? point into the Brillouin zone, such as the effective-mass approximation for the optical-matrix elements, can be misleading. For certain cases, the heavy- and light-hole isoenergetic surfaces form complex figures resembling the indicatrix of birefringent biaxial crystals. The symmetry of the hole wave functions causes dichroism for photon energies close to the gap energy, while the crystal becomes optically isotropic for larger photon energies. Numerical results are presented for the eight-band k?p model of biaxially strained bulklike 1.3-?mInxGa1-xAsyP1-y on InP being an important material in optoelectronics.

k?p results for the absolute absorption coefficients of GaAs and biaxially strained ZnTe  

Science Journals Connector (OSTI)

Our calculations of the absolute absorption coefficients of GaAs and biaxially strained ZnTe single crystal layers is based on a 1414 k?p model description of the band structure close to the Brillouin-zone center of the direct-gap zinc-blende semiconductors. The parameters of this model (momentum matrix elements, band separations at the ? point, effective masses) are known from fitting to independent experiments. The interband absorption continuum near the fundamental gap is calculated by multiplying the single-particle absorption coefficients from heavy- and light-hole valence bands with separate Sommerfeld corrections in order to account for the electron-hole interaction. Our theoretical results, which are obtained without any fitting parameters, are in good quantitative agreement with experimental data.

Analog of the k?p theory for a localized-orbital description of the band structure of zinc-blende-structure semiconductors  

Science Journals Connector (OSTI)

The k?p method is based on a completely general formulation but contains parameters defined in terms of series involving matrix elements of the momentum operator. On the other hand, current band-structure calculations lead to a knowledge of the Hamiltonian matrix in a finite basis set per unit cell. It is thus of great interest to devise a systematic method allowing one to relate directly the effective-mass tensors to these Hamiltonian matrix elements. This is done here by a formulation close to the original k?p theory, applied to a tight-binding description of the band structure. The effects due to the inclusion of spin-orbit coupling and strain are discussed. The origin of the crossing between the light- and heavy-hole bands under uniaxial strain is analyzed. Extensions of the method to other descriptions of the band structure, as well as to phonon-dispersion curves, are briefly presented.

In the framework of the well-known k?p Kane band theory, accurate analytical approximations of conduction- and valence-band dispersion of direct-band-gap zinc-blende-structure semiconductors are derived when the spin-orbit-splitting energy does not exceed the band-gap energy. These approximations include the interactions with the remote bands. The expressions of the eigenfunctions are also obtained. The present analysis elucidates and unifies previous analytical band descriptions.

Solutions of the k?p Hamiltonian in confined systems with a highly nonparabolic dispersion and consequences for AlAs quantum wells  

Science Journals Connector (OSTI)

We present two methods to deal with quantum confinement in systems with a camels back dispersion. The two-band Hamiltonian for AlAs X states is solved both by analytical and transfer-matrix methods. The latter offers a general yet relatively simple and flexible way to deal with all types of potential profile. We calculate energy spectra and wave functions for single GaAs/AlAs/GaAs quantum wells and discuss the implications of our results on ?-XZ mixing. We also determine the Landau level fan for AlAs systems with the magnetic field perpendicular to the camels back axis. In both cases, we find the confined energies and wave functions to be greatly affected by the k?p interaction. We also show that the well-known type Itype II transition for GaAs/AlAs superlattices is modeled correctly by taking the k?p interaction into account, and that previous effective mass treatments are not reliable. In addition, the crossover from XZ to XX,Y ground states in AlAs confined systems is reevaluated.

Measurement of $Br(H\\to c\\bar c,gg)/Br(H\\to b\\bar b)$ in $e^+e^-$ colliders at center-of-mass energy of 300 GeV  

E-Print Network (OSTI)

Once a light Higgs boson is discovered at a future e+e- collider, the next target at the collider will be precise measurements of the Higgs boson properties. In this paper we report a simulation study on the measurement of the ratio Br(H->cc,gg)/Br(H->bb) at center of mass energy of 300 GeV, and show the possibility to constrain MSSM parameters from the measurement.

Energy Dependence of $K/\\pi$, $p/\\pi$, and $K/p$ Fluctuations in Au+Au Collisions from $\\rm \\sqrt{s_{NN}}$ = 7.7 to 200 GeV  

E-Print Network (OSTI)

A search for the quantum chromodynamics (QCD) critical point was performed by the STAR experiment at the Relativistic Heavy Ion Collider, using dynamical fluctuations of unlike particle pairs. Heavy-ion collisions were studied over a large range of collision energies with homogeneous acceptance and excellent particle identification, covering a significant range in the QCD phase diagram where a critical point may be located. Dynamical $K/\\pi$, $p/\\pi$, and $K/p$ fluctuations as measured by the STAR experiment in central 0-5% Au+Au collisions from center-of-mass collision energies $\\rm \\sqrt{s_{NN}}$ = 7.7 to 200 GeV are presented.

Evaluation of matrix elements of the 88 k?p Hamiltonian with k-dependent spin-orbit contributions for the zinc-blende structure of GaAs  

Science Journals Connector (OSTI)

The k?p method of band-structure calculation provides a detailed description of a crystals energy dispersion near a high symmetry point in the first Brillouin zone. The resulting parameters of this calculation are a series of momentum matrix elements. Presented here is a set of band-structure parameters for the zinc-blende structure of GaAs at the ? point that takes the lack of inversion symmetry into account as well as k-dependent spin-orbit contributions to the Hamiltonian. A comprehensive optimization was performed in order to satisfy effective mass data as well as conduction band spin-splitting data. It was found that the lack of inversion symmetry has a profound influence on the nonparabolicity of the conduction band and the contribution of the k-dependent spin-orbit effect cannot be ignored in the calculation of the effective mass of the conduction, light hole, and spin-orbit bands. 1996 The American Physical Society.

Eight-band kp modeling of InAs/InGaAsSb type-II W-design quantum well structures for interband cascade lasers emitting in a broad range of mid infrared  

SciTech Connect

Band structure properties of the type-II W-design AlSb/InAs/GaIn(As)Sb/InAs/AlSb quantum wells have been investigated theoretically in a systematic manner and with respect to their use in the active region of interband cascade laser for a broad range of emission in mid infrared between below 3 to beyond 10??m. Eight-band kp approach has been utilized to calculate the electronic subbands. The fundamental optical transition energy and the corresponding oscillator strength have been determined in function of the thickness of InAs and GaIn(As)Sb layers and the composition of the latter. There have been considered active structures on two types of relevant substrates, GaSb and InAs, introducing slightly modified strain conditions. Additionally, the effect of external electric field has been taken into account to simulate the conditions occurring in the operational devices. The results show that introducing arsenic as fourth element into the valence band well of the type-II W-design system, and then altering its composition, can efficiently enhance the transition oscillator strength and allow additionally increasing the emission wavelength, which makes this solution prospective for improved performance and long wavelength interband cascade lasers.

SU?GG?J?14: Failure Mode and Effect Analysis (FMEA)?Based Quality Assurance for Dynamic MLC Tracking Systems  

Science Journals Connector (OSTI)

Purpose: Effective QA for newly introduced radiotherapy technology has received increased attention within the radiotherapy community and the general public. This work aims to develop and implement a FMEA?based quality management (QM) framework for dynamic MLC (DMLC) tumortracking systems.Methods: A systematic FMEA was performed for a prototype tumortracking system that uses the Calypso system for position monitoring and a DMLC for real?time beam adaptation. A process tree of DMLC tracking delivery was mapped and potential failure modes were identified. For each failure mode a risk probability number (RPN 1:1000) was calculated from the product of the probability of occurrence severity of effect and detectability of failure. Based on the insights obtained from FMEA commissioning and QA procedures were developed to check (i) coordinate transformation (ii) system latency (iii) delivery accuracy (iv) delivery efficiency and (v) system response to error conditions. Results: Failures modes with RPN ? 20 were: delivery accuracy efficiency and data communication integrity. These were recommended to be tested monthly. Failure modes with RPN FMEA proved to be a powerful and flexible tool to develop a QM framework for DMLC tracking. We conclude that the use of FMEA ensures efficient allocation of valuable clinical resources because the most critical failure modes receive the most attention. Finally consistent with the goals of FMEA this framework can serve as the basis of a dynamic QM program that is continuously updated with increasing intra? and inter?institutional experience.

SU?GG?I?110: Study of the Use of Protons and Carbon Ions for Patient Imaging  

Science Journals Connector (OSTI)

Purpose: An evaluation of protons and carbon?ions for generating radiographicimages is performed. The contrast signal?to?noise ratio energy and spatial spread of protons and carbon ions passing through various tissues defined in ICRU were evaluated for different incident energies. Method and Materials: The Monte Carlo package GEANT4 was used to simulate the transport of protons/carbon?ions through different ICRU soft tissues such as: H 2 O lung adipose tissue soft?tissue muscle cartilage and cortical bone. Proton energies were 150300 MeV and carbon ion energies were 360500 AMeV. In order to study how the energy and the spatial spread of the beam varies for different thicknesses of ICRU tissues. The incident proton and carbon ions were pencil beam like with spot size of 1 micron?meter and with direction of motion perpendicular to the surface of the phantom. The spatial spread of exit particles is obtained from the standard deviation of the position of the exit particles relative to the center of the incident beam.Results: The spatial?spread of 200300MeV protons and 360500 AMeV carbon?ions passing through 20cm of soft?tissue representing a typical body thickness was respectively 2mm and 0.05mm. Carbon?ions allow significantly better spatial resolution than protonbeams. The mean exit energy for protons and carbon?ions was respectively 87223MeV and 113320 AMeV. The energy spread of the protons and carbon?ions was respectively 5.18.0MeV and 1.280.91 AMeV. The contrast of 10mm of bone?to?soft tissue is 7.20%2.1% and 59%53% respectively for protons and carbon?ions. Conclusions The spatial?resolution attainable with protons and carbon?ions passing through 20cm is respectively 2mm and 0.050mm. The significantly heavier carbon ions suffer less multiple Coulomb scatter within the patient than the protons and therefore can allow sharper images.Contrast of bone?to?tissue is higher in carbon?ions than in protons. The high contrast makes this tool attractive for online treatment?position?verification.

SU?GG?T?509: Development of a Database and Software Tools for Outcome Analysis of Breast Cancer Radiotherapy  

Science Journals Connector (OSTI)

Purpose:Dose?volume response data for breast cancerradiotherapy (RT) are generally lacking. The purpose of this work is to develop a database and software tools to facilitate the analyses of short? and long?term radiationdose?volume responses of breast cancer RT. Method and Materials: As a part of the project aiming to develop the Research Analysis Platform and IGRTDatabases (RAPID) a database consisting of modules to enter breast cancer patient's demographic diagnosis and staging radiation treatment parameters dose?volume data and follow?up information was developed using FileMaker databasesoftware. Data is tabulated in Microsoft Excel and imported into RAPID. Treatment related toxicity definitions for the breast RT were incorporated into the database to standardize the documentation of toxicity which facilitates statistical and outcome analysis. Relevant data can be exported from the database for use with auxiliary software tools for dose?volume response analysis and outcome meta?analysis. RAPID will be integrated with other software tools such as CERR AutoEUD and DREES to facilitate modeling of dose?volume responses for treatment planning. Results: A database and software tools with capabilities of searching sorting any correlating input parameters are developed. Clinical data for breast cancer patients treated in our institution in the last 10 years with CT?based dosimetry planning are being entered into the database. A FileMaker server has been installed in our department to host RAPID and allows registered users to remotely access password?protected clinical data. Conclusions: A database and auxiliary tools as part of a software platform RAPID has been developed to facilitate storing clinical data and deriving dose?volume responses for breast cancer patients treated with radiation therapy. This research is supported by the Folkman Foundation

SU?GG?J?167: Resonant X?Ray Irradiation of High?Z Nanoparticles for Cancer Theranostics  

Science Journals Connector (OSTI)

Purpose: Broadband X?ray sources employed in current cancer therapy are indiscriminant of tissue composition. We demonstrate significant dose enhancement by high?Z (HZ) sensitizing agents at resonant energies below the K?edge. This is of particular interest in cancer theranostics using agents such as goldnanoparticles embedded in malignant tissue.Method and Materials: Relativistic R?matrix calculations were performed for radiative transitions and photoionization for many HZ elements from Fe to U. Accurate cross section data and monochromatic attenuation coefficients were computed in energy ranges where the large k?a resonance complexes occur. Scaling laws up to HZ species such as Pt Au and U are studied. Depth dose curves based on photon transport in a numerical model containing muscle bone and tumor with 1mg/cc concentration of goldnanoparticles were calculated using the new resonant atomic data and compared with those calculated using standard evaluated data. Results: Giant resonance complexes were identified in all HZ species at energies below the respective K edge. For example the resonant attenuation coefficient for k?? transitions in Fe and Au are more than 1000 times higher than at their K edge. The average absorption efficiency in cm2/g of Au at ?68 keV is 7400 compared to 3.3 at the Au K?edge and only about 0.2 for C N O and 0.24 for Ca. The gold resonance complexes lie in the range 6780 keV below the K?edge. The calculations reveal preferential dose deposition ratio of 3 to 4 between the goldnanoparticle?bearingtumor and soft tissue (including surface) or bone. Conclusion: Opportunities exist to specifically target HZ?bearing tumors while sparing normal tissue at monochromatic or narrowband X?ray sources tuned to resonant energies. We identify and discuss potential sources for the generation of sufficiently intense K?alpha resonant radiation such as laser produced plasma devices and electron?beam ion traps.

SU?GG?J?138: Effect of RF Pulse Dwell Time on Eddy Current and Motion Compensation in Multi?Shot Diffusion?Weighted MRI  

Science Journals Connector (OSTI)

Purpose: Diffusion?weighted (DW) MRI can provide information to improve target delineation in radiation treatment planning. The widely used twice?refocused spin?echo (TRSE) sequence is optimized to diminish eddy current?induced geometric distortions. However the TRSE sequence imposes a longer minimum echo time which precludes its use in acquiring DW images in tissues with short T2s. We found that radiofrequency (RF) pulse dwell times can also affect DW image quality and demonstrate that high?fidelity multi?shot DW images can be obtained using the non?optimized Stejkal and Tanner (ST) sequence when short RF pulse dwell times are employed. Method and Materials: A pulse sequence of our own design was implemented to acquire DW images using ST and TRSE diffusion?encoding schemes with 25 usec and 2 usec RF pulse dwell times. Single? and multi?shot spiral DW images (b=0 1000 s/mm2) of phantom and healthy volunteer were acquired on a 3.0T Siemens Verio scanner.Images were reconstructed offline using custom software developed at our Institution. Results: Single? and multi?shot non?DW images did not exhibit a dependence on RF pulse dwell time. Furthermore single?shot DW images acquired with the TRSE method did not exhibit a dependence on RF pulse dwell time. However multi?shot DW images exhibited significant artifacts at long RF pulse dwell times even for the optimized TRSE method. Reducing the RF pulse dwell time improved the inherent immunity of the sequences to eddy current and motion?induced artifacts permitting acquisition of high?fidelity multi?shot DW images even with the non?optimized ST method. Conclusions: Compensation of eddy current and motion?induced artifacts in multi?shot DW imaging can be affected by choice of RF pulse dwell time. High?fidelity multi?shot DW images of short T2 tissues can be obtained using the non?optimized traditional ST method so long as the RF pulse dwell time is kept short.

SciTech Connect

This report presents data and limited analysis from the 21-Rod Bundle Flow Blockage Task of the Full-Length Emergency Cooling Heat Transfer Separate Effects and Systems Effects Test Program (FLECHT SEASET). The tests consisted of forced and gravity reflooding tests utilizing electrical heater rods with a cosine axial power profile to simulate PWR nuclear core fuel rod arrays. Steam cooling and hydraulic characteristics tests were also conducted. These tests were utilized to determine effects of various flow blockage configurations (shapes and distributions) on reflooding behavior, to aid in development/assessment of computational models in predicting reflooding behavior of flow blockage configurations, and to screen flow blockage configurations for future 163-rod flow blockage bundle tests.

In this paper, we investigate the non-autonomous discrete Kadomtsev-Petviashvili (KP) system in terms of generalized Cauchy matrix approach. These equations include non-autonomous bilinear lattice KP equation, non-autonomous lattice potential KP equation, non-autonomous lattice potential modified KP equation, non-autonomous asymmetric lattice potential modified KP equation, non-autonomous lattice Schwarzian KP equation and non-autonomous lattice KP-type Nijhoff-Quispel-Capel equation. By introducing point transformations, all the equations are described as simplified forms, where the lattice parameters are absorbed. Several kinds of solutions more than multi-soliton solutions to these equations are derived by solving determining equation set. Lax representations for these equations are also discussed.

Heavy metals in eggshells of cattle egret (Bubulcus ibis) and little egret (Egretta garzetta) from the Punjab province, Pakistan  

Science Journals Connector (OSTI)

Concentrations of nine trace metals were determined to assess site-specific and species-specific differences using Fast Sequential Atomic Absorption Spectrophotometer (Varian FAAS-240) in eggshells of Bubulcus ibis and Egretta garzetta from seven heronries in the Punjab province, Pakistan. Pattern of metal concentration followed the order: Fe>Zn>Pb>Mn>Cd>Cr>Li>Cu>Ni. Greater mean concentrations of Mn(1.17?g/g), Ni(0.11?g/g), Pb(1.49?g/g), Cd(0.88?g/g), Cr(0.7?g/g), Cu(0.20?g/g) and Li(0.27?g/g) were recorded in little egret. Mean concentrations of Mn, Pb, and Cr, (3.98, 5.4, 0.8?g/g) were significantly higher in eggshells collected from Shorkot; Cu, Zn and Ni (0.19, 13.0, 0.12?g/g) from the Trimu Headwork; Cd (1.23?g/g) from Jhang Faisalabad Road and Fe (67.98?g/g) from Mailsi. Multivariate analyses indicated that Mn, Pb, Cd, Ni, Cu, Cr and Zn were associated with anthropogenic activities and Fe and Li with natural origin. This study provides the baseline data for a monitoring program and revealed that egg-shells can serve as a bio-monitor of local metal contamination.

Speciation study of the heavy metals in commercially available recharge cards coatings in Nigeria and the health implication  

Science Journals Connector (OSTI)

Abstract This work assessed levels of heavy metals exposure from silver coatings of mobile phones recharge cards of three major companies (designated as A, B and C) with price denominations 100, 200 and 400 from companies A, B and C respectively, which were carefully scratched using a plastic scraper into a glass tube. The coatings were acid digested for total metal concentration, while speciation experiment for Mn, Cu, Cd and Pb was carried out. Total metals and speciation analysis were done using AAS and XRF techniques. The total metal concentration from XRF analysis was in the range: Ca (702140?g/g), K (204930?g/g), Sc (80270?g/g), Ti (153012,580?g/g), Fe (506660?g/g), Ni (202040?g/g), Cu (20850?g/g) and Zn (40460?g/g). Cr had the lowest concentration (10?g/g) in A ( 400) while Ti had the highest concentration (12,580?g/g) in C ( 500) for all the coatings analyzed. AAS and XRF results agreed closely except for Fe with higher concentration. A ( 100) contained high concentration of the metals compared with others. Speciation study identified Mn as the most mobile element when present in the environment.

A high-resolution and multi-year emissions inventory for biomass burning in Southeast Asia during 20012010  

Science Journals Connector (OSTI)

Abstract Biomass burning (BB) emissions from forest fires, agricultural waste burning, and peatland combustion contain large amounts of greenhouse gases (e.g., CO2, CH4, and N2O), which significantly impact ecosystem productivity, global atmospheric chemistry, and climate change. With the help of recently released satellite products, biomass density based on satellite and observation data, and spatiotemporal variable combustion factors, this study developed a new high-resolution and multi-year emissions inventory for BB in Southeast Asia (SEA) during 20012010. The 1-km grid was effective for quantifying emissions from small-sized fires that were frequently misinterpreted by coarse grid data due to their large smoothed pixels. The average annual BB emissions in SEA during 20012010 were 277Gg SO2, 1125Gg NOx, 55,388Gg CO, 3831Gg NMVOC, 553Gg NH3, 324Gg BC, 2406Gg OC, 3832Gg CH4, 817,809Gg CO2, and 99Gg N2O. Emissions were high in western Myanmar, Northern Thailand, eastern Cambodia, northern Laos, and South Sumatra and South Kalimantan of Indonesia. Emissions from forest burning were the dominant contributor to the total emissions among all land types. The spatial pattern of BB emissions was consistent with that of the burned areas. In addition, BB emissions exhibited similar temporal trends from 2001 to 2010, with strong interannual and intraannual variability. Interannual and intraannual emission peaks were seen during 2004, 2007, 2010, and JanuaryMarch and AugustOctober, respectively.

An angular-selective electron source for the KATRIN experiment  

E-Print Network (OSTI)

The KATRIN experiment is going to search for the average mass of the electron antineutrino with a sensitivity of 0.2 eV/c2. It uses a retardation spectrometer of MAC-E filter type to accurately measure the shape of the electron spectrum at the endpoint of tritium beta decay. In order to achieve the planned sensitivity the transmission properties of the spectrometer have to be understood with high precision for all initial conditions. For this purpose an electron source has been developed that emits single electrons at adjustable total energy and adjustable emission angle. The emission is pointlike and can be moved across the full flux tube that is imaged onto the detector. Here, we demonstrate that this novel type of electron source can be used to investigate the transmission properties of a MAC-E filter in detail.

Spin-on-doping for output power improvement of silicon nanowire array based thermoelectric power generators  

SciTech Connect

The output power of a silicon nanowire array (NWA)-bulk thermoelectric power generator (TEG) with Cu contacts is improved by spin-on-doping (SOD). The Si NWAs used in this work are fabricated via metal assisted chemical etching (MACE) of 0.010.02 ? cm resistivity n- and p-type bulk, converting ?4% of the bulk thickness into NWs. The MACE process is adapted to ensure crystalline NWs. Current-voltage and Seebeck voltage-temperature measurements show that while SOD mainly influences the contact resistance in bulk, it influences both contact resistance and power factor in NWA-bulk based TEGs. According to our experiments, using Si NWAs in combination with SOD increases the output power by an order of 3 under the same heating power due to an increased power factor, decreased thermal conductivity of the NWA and reduced Si-Cu contact resistance.

Exotic Trajectories and the Pomeranchukon in a Veneziano Representation for KN and KN Scattering  

Science Journals Connector (OSTI)

The KN and KN scattering processes are studied within the framework of the Veneziano model. Apart from the normal trajectories, ?, ?, ?, and Y1*, appearing in these processes, for the first time the contribution of the Pomeranchuk trajectory is included in a quantitative manner. An immediate consequence, if one is to avoid exchange degeneracy of the Pomeranchukon. is that baryon trajectories with exotic quantum numbers have to be introduced also. With reasonable parameters for the normal as well as the exotic trajectories, good agreement with a wide range of experimental data for KN and KN scattering is obtained. In particular, we fit K-p and K+n charge-exchange differential cross sections, K-p and K+p elastic scattering in both forward and backward directions, K-p and K+p total cross sections, and the polarization parameters for K-p and K+p elastic scattering. The parameters for the best fit imply reasonable properties of the normal as well as the exotic trajectories - the absence of parity partners of ?(1115), ??(1520), ?(1190), and Y1*(1385), and the correct signature property for the Pomeranchuk trajectory. The normal trajectories come out with a slope of about 1 GeV-2. The slope of the Pomeranchukon, which is the same for the exotic trajectories, is found from the best fits to be about 0.75 GeV-2, while the exotic trajectories have an intercept of about - 3.4. The properties of resonances lying on the normal and exotic trajectories are discussed.

Shear Viscosity in a Gluon Gas  

Science Journals Connector (OSTI)

The relation of the shear viscosity coefficient to the recently introduced transport rate is derived within relativistic kinetic theory. We calculate the shear viscosity over entropy ratio ?/s for a gluon gas, which involves elastic gg?gg perturbative QCD (PQCD) scatterings as well as inelastic gg?ggg PQCD bremsstrahlung. For ?s=0.3 we find ?/s=0.13 and for ?s=0.6, ?/s=0.076. The small ?/s values, which suggest strongly coupled systems, are due to the gluon bremsstrahlung incorporated.

A decreasing gravitational constant, G, coupled with angular momentum conservation is expected to increrase a planetary semimajor axis, a, as \\dot a/a=-\\dot G/G. Analysis of lunar laser ranging data strongly limits such temporal variations and constrains a local (~1 AU) scale expansion of the solar system as \\dot a/a=-\\dot G/G =-(4\\pm9)\\times10^{-13} yr^{-1}, including that due to cosmological effects.

Synthesis, adsorption and regeneration of nanoporous silica aerogel and silica aerogel-activated carbon composites  

Science Journals Connector (OSTI)

Abstract Usage of aerogels as an adsorbent has become more widespread because of its specifications such as high porosity and specific surface. Nanometer silica aerogel and silica aerogel-activated carbon composites were synthesized using a water glass precursor by ambient pressure drying method. Then, the adsorption capacity of synthesized adsorbents was studied in terms of benzene and ethyl benzene adsorption by chromatography method for continuous and batch testing. Results showed that silica aerogel and silica aerogel-activated carbon composites had high tendency for benzene and ethyl benzene adsorption. Silica aerogel showed maximum adsorption capacity of 2.3gg?1 and 0.7gg?1 in static adsorption of benzene and ethyl benzene respectively. Also, in dynamic adsorption of benzene and ethyl benzene, silica aerogel had maximum equilibrium adsorption capacity of 0.954gg?1 and 0.219gg?1 respectively. Minimum equilibrium adsorption capacity in benzene and ethyl benzene static adsorption was related to activated carbon with 0.7gg?1 and silica aerogel2wt% activated carbon with 0.25gg?1 respectively. After adsorption process, silica aerogel and silica aerogel0.5wt% activated carbon composite were regenerated by solvent extractionthermal treatment method and, after at least 15 adsorption/desorption cycles, their adsorption capacity became fixed.

Dynamic behavior of ion acoustic waves in electron-positron-ion magnetoplasmas with superthermal electrons and positrons  

SciTech Connect

The dynamic behavior of ion acoustic waves in electron-positron-ion magnetoplasmas with superthermal electrons and positrons has been investigated in the framework of perturbed and non-perturbed Kadomtsev-Petviashili (KP) equations. Applying the reductive perturbation technique, we have derived the KP equation in electron-positron-ion magnetoplasma with kappa distributed electrons and positrons. Bifurcations of ion acoustic traveling waves of the KP equation are presented. Using the bifurcation theory of planar dynamical systems, the existence of the solitary wave solutions and the periodic traveling wave solutions has been established. Two exact solutions of these waves have been derived depending on the system parameters. Then, using the Hirota's direct method, we have obtained two-soliton and three-soliton solutions of the KP equation. The effect of the spectral index ? on propagations of the two-soliton and the three-soliton has been shown. Considering an external periodic perturbation, we have presented the quasi periodic behavior of ion acoustic waves in electron-positron-ion magnetoplasmas.

Science Journals Connector (OSTI)

Abstract Jackfruit (Artocarpus heterophyllus Lam., family: Moraceae) seed starch (JFSS)gellan gum (GG) mucoadhesive beads containing metformin \\{HCl\\} were developed through ionotropic gelation technique. The effect of GG to JFSS ratio and CaCl2 concentration on the drug encapsulation efficiency (DEE, %) and cumulative drug release at 10h (R10h, %) was optimized and analyzed using response surface methodology based on 32 factorial design. The optimized JFSSGG beads containing metformin \\{HCl\\} showed DEE of 92.674.46%, \\{R10h\\} of 61.302.37%, and mean diameter of 1.670.27mm. The optimized beads showed pH-dependent swelling and mucoadhesivity with the goat intestinal mucosa. The in vitro drug release from all these JFSSGG beads containing metformin \\{HCl\\} was followed zero-order pattern (R2=0.99070.9975) with super case-II transport mechanism over a period of 10h. The beads were also characterized by SEM and FTIR. The optimized JFSSGG beads containing metformin \\{HCl\\} exhibited significant hypoglycemic effect in alloxan-induced diabetic rats over prolonged period after oral administration.

OECD MCCI project long-term 2-D molten core concrete interaction test design report, Rev. 0. September 30, 2002.  

SciTech Connect

The Melt Attack and Coolability Experiments (MACE) program at Argonne National Laboratory addressed the issue of the ability of water to cool and thermally stabilize a molten core-concrete interaction when the reactants are flooded from above. These tests provided data regarding the nature of corium interactions with concrete, the heat transfer rates from the melt to the overlying water pool, and the role of noncondensable gases in the mixing processes that contribute to melt quenching. As a follow-on program to MACE, The Melt Coolability and Concrete Interaction Experiments (MCCI) project is conducting reactor material experiments and associated analysis to achieve the following two technical objectives: (1) resolve the ex-vessel debris coolability issue through a program that focuses on providing both confirmatory evidence and test data for the coolability mechanisms identified in MACE integral effects tests, and (2) address remaining uncertainties related to long-term two-dimensional molten core-concrete interactions under both wet and dry cavity conditions. Achievement of these two objectives will demonstrate the efficacy of severe accident management guidelines for existing plants, and provide the technical basis for better containment designs for future plants. In terms of the first program objective, the Small-Scale Water Ingression and Crust Strength (SSWICS) test series has been initiated to provide fundamental information on the ability of water to ingress into cracks and fissures that form in the debris during quench, thereby augmenting the otherwise conduction-limited heat transfer process. A test plan for Melt Eruption Separate Effects Tests (MESET) has also been developed to provide information on the extent of crust growth and melt eruptions as a function of gas sparging rate under well-controlled experiment conditions. In terms of the second program objective, the project Management Board (MB) has approved startup activities required to carry out experiments to address remaining uncertainties related to long-term two-dimensional molten core-concrete interaction. In particular, for both wet and dry cavity conditions, there is uncertainty insofar as evaluating the lateral vs. axial power split during a core-concrete interaction due to a lack of experiment data. As a result, there are differences in the 2-D cavity erosion predicted by codes such as MELCOR, WECHSL, and COSACO. The first step towards generating this data is to produce a test plan for review by the Project Review Group (PRG). The purpose of this document is to provide this plan.

Achievement of these two program objectives will demonstrate the efficacy of severe accident management guidelines for existing plants, and provide the technical basis for better containment designs for future plants. In terms of satisfying these objectives, the Management Board (MB) approved the conduct of two long-term 2-D Core-Concrete Interaction (CCI) experiments designed to provide information in several areas, including: (i) lateral vs. axial power split during dry core-concrete interaction, (ii) integral debris coolability data following late phase flooding, and (iii) data regarding the nature and extent of the cooling transient following breach of the crust formed at the melt-water interface. This data report provides thermal hydraulic test results from the CCI-1 experiment, which was conducted on December 19, 2003. Test specifications for CCI-1 are provided in Table 1-1. This experiment investigated the interaction of a fully oxidized 400 kg PWR core melt, initially containing 8 wt % calcined siliceous concrete, with a specially designed two-dimensional siliceous concrete test section with an initial cross-sectional area of 50 cm x 50 cm. The report begins by providing a summary description of the CCI-1 test apparatus and operating procedures, followed by presentation of the thermal-hydraulic results. The posttest debris examination results will be provided in a subsequent publication. Observations drawn within this report regarding the overall cavity erosion behavior may be subject to revision once the posttest examinations are completed, since these examinations will fully reveal the final cavity shape.

A Novel Statistical Channel Model for Turbulence-Induced Fading in Free-Space Optical Systems  

E-Print Network (OSTI)

In this paper, we propose a new probability distribution function which accurately describes turbulence-induced fading under a wide range of turbulence conditions. The proposed model, termed Double Generalized Gamma (Double GG), is based on a doubly stochastic theory of scintillation and developed via the product of two Generalized Gamma (GG) distributions. The proposed Double GG distribution generalizes many existing turbulence channel models and provides an excellent fit to the published plane and spherical waves simulation data. Using this new statistical channel model, we derive closed form expressions for the outage probability and the average bit error as well as corresponding asymptotic expressions of free-space optical communication systems over turbulence channels. We demonstrate that our derived expressions cover many existing results in the literature earlier reported for Gamma-Gamma, Double-Weibull and K channels as special cases.

An automated integration-free path-integral method based on Kleinerts variational perturbation theory  

Science Journals Connector (OSTI)

Based on Kleinerts variational perturbation (KP) theory [Path Integrals in Quantum Mechanics Statistics Polymer Physics and Financial Markets 3rd ed. (World Scientific Singapore 2004)] we present an analytic path-integral approach for computing the effective centroid potential. The approach enables the KP theory to be applied to any realistic systems beyond the first-order perturbation (i.e. the original Feynman-Kleinert [Phys. Rev. A34 5080 (1986)] variational method). Accurate values are obtained for several systems in which exact quantum results are known. Furthermore the computed kinetic isotope effects for a series of proton transferreactions in which the potential energy surfaces are evaluated by density-functional theory are in good accordance with experiments. We hope that our method could be used by non-path-integral experts or experimentalists as a black box for any given system.

Fermionic construction of partition function for multi-matrix models and multi-component TL hierarchy  

E-Print Network (OSTI)

We use $p$-component fermions $(p=2,3,...)$ to present $(2p-2)N$-fold integrals as a fermionic expectation value. This yields fermionic representation for various $(2p-2)$-matrix models. Links with the $p$-component KP hierarchy and also with the $p$-component TL hierarchy are discussed. We show that the set of all (but two) flows of $p$-component TL changes standard matrix models to new ones.

Cirrus Radiative Properties in the Tropical Western Pacific Cirrus Radiative Properties in the Tropical Western Pacific J. M. Comstock and T. P. Ackerman Pacific Northwest National Laboratory Richland, Washington G. G. Mace University of Utah Salt Lake City, Utah Introduction Cirrus clouds in tropical regions are often located high in the cold upper troposphere and have low optical depths. In addition, tropical cirrus often extend in large sheets up to 1000 km horizontally, which may have a large influence on the energy budget of the atmosphere. Characterizing the location and radiative properties of cirrus clouds is an important step in understanding the processes that generate and maintain these cold, thin cirrus clouds and their impact on upper tropospheric dynamics.

Cirrus Horizontal Inhomogeneity and OLR Bias Cirrus Horizontal Inhomogeneity and OLR Bias Q. Fu and B. Carlin Department of Oceanography Dalhousie University Halifax, Nova Scotia Canada G. G. Mace Department of Meteorology University of Utah Salt Lake City, Utah Introduction Clouds exhibit dramatic variabilities at spatial scales smaller than typical grid cells of large-scale models used to study climate and weather. These unresolved cloud fluctuations are potentially important for parameterizations of both cloud radiative effects and cloud microphysical processes (e.g., Harshvardhan and Randall 1985; Jacob and Kein 1999). It is now well accepted that neglect of cloud subscale variability can seriously bias model estimates of the disposition of solar radiation in the earth- atmosphere system (e.g., Cahalan et al. 1994a; Barker 1996).

OECD/MCCI 2-D Core Concrete Interaction (CCI) tests : final report February 28, 2006.  

SciTech Connect

Although extensive research has been conducted over the last several years in the areas of Core-Concrete Interaction (CCI) and debris coolability, two important issues warrant further investigation. The first issue concerns the effectiveness of water in terminating a CCI by flooding the interacting masses from above, thereby quenching the molten core debris and rendering it permanently coolable. This safety issue was investigated in the EPRI-sponsored Melt Attack and Coolability Experiments (MACE) program. The approach was to conduct large scale, integral-type reactor materials experiments with core melt masses ranging up to two metric tons. These experiments provided unique, and for the most part repeatable, indications of heat transfer mechanism(s) that could provide long term debris cooling. However, the results did not demonstrate definitively that a melt would always be completely quenched. This was due to the fact that the crust anchored to the test section sidewalls in every test, which led to melt/crust separation, even at the largest test section lateral span of 1.20 m. This decoupling is not expected for a typical reactor cavity, which has a span of 5-6 m. Even though the crust may mechanically bond to the reactor cavity walls, the weight of the coolant and the crust itself is expected to periodically fracture the crust and restore contact with the melt. Although crust fracturing does not ensure that coolability will be achieved, it nonetheless provides a pathway for water to recontact the underlying melt, thereby allowing other debris cooling mechanisms to proceed. A related task of the current program, which is not addressed in this particular report, is to measure crust strength to check the hypothesis that a corium crust would not be strong enough to sustain melt/crust separation in a plant accident. The second important issue concerns long-term, two-dimensional concrete ablation by a prototypic core oxide melt. As discussed by Foit the existing reactor material database for dry cavity conditions is solely one-dimensional. Although the MACE Scoping Test was carried out with a two-dimensional concrete cavity, the interaction was flooded soon after ablation was initiated to investigate debris coolability. Moreover, due to the scoping nature of this test, the apparatus was minimally instrumented and therefore the results are of limited value from the code validation viewpoint. Aside from the MACE program, the COTELS test series also investigated 2-D CCI under flooded cavity conditions. However, the input power density for these tests was quite high relative to the prototypic case. Finally, the BETA test series provided valuable data on 2-D core concrete interaction under dry cavity conditions, but these tests focused on investigating the interaction of the metallic (steel) phase with concrete. Due to these limitations, there is significant uncertainty in the partition of energy dissipated for the ablation of concrete in the lateral and axial directions under dry cavity conditions for the case of a core oxide melt. Accurate knowledge of this 'power split' is important in the evaluation of the consequences of an ex-vessel severe accident; e.g., lateral erosion can undermine containment structures, while axial erosion can penetrate the basemat, leading to ground contamination and/or possible containment bypass. As a result of this uncertainty, there are still substantial differences among computer codes in the prediction of 2-D cavity erosion behavior under both wet and dry cavity conditions. In light of the above issues, the OECD-sponsored Melt Coolability and Concrete Interaction (MCCI) program was initiated at Argonne National Laboratory. The project conducted reactor materials experiments and associated analysis to achieve the following technical objectives: (1) resolve the ex-vessel debris coolability issue through a program that focused on providing both confirmatory evidence and test data for the coolability mechanisms identified in MACE integral effects tests, and (2) address remaining uncertainties relat

Production of K+K? pairs in proton-proton collisions below the ? meson threshold  

The pp?ppK+K? reaction was measured below the ? threshold at a beam energy of 2.568 GeV using the COSY-ANKE magnetic spectrometer. By assuming that the four-body phase space is distorted only by the product of two-body final-state interactions, fits to a variety of one-dimensional distributions permit the evaluation of differential and total cross sections. The shapes of the distributions in the Kp and Kpp invariant masses are reproduced only if the K?p interaction is even stronger than that found at higher energy. The cusp effect in the K+K? distribution at the K0K{bar}0 threshold is much more clear and some evidence is also found for coupling between the K?p and K?0n channels. However, the energy dependence of the total cross section cannot be reproduced by considering only a simple product of such pairwise final-state interactions.

Solar, geomagnetic and cosmic ray intensity changes, preceding the cyclone appearances around Mexico  

Science Journals Connector (OSTI)

Recently it has been suggested that there exist specific changes in the cosmic ray intensity and some solar and geomagnetic parameters during the days, preceding the hurricane appearances over the North Atlantic Ocean. To understand better these phenomena, data for all hurricanes born not only over the Atlantic but also over the Pacific waters in the last 55 years that hit the Mexican borders were elaborated. As basic hurricane parameters the maximum rotational velocity and the estimated total energy were used. To avoid any interference all hurricanes, overlapping the preceding ones with more than 20 days were not included. Then the behavior of the cosmic ray (CR) intensity, the sunspot (SS) numbers, and the geomagnetic parameters (AP) and (KP) in 35 days prior and 20 days after the cyclone start were investigated. The CR, SS, AP and KP showed much more intensive disturbances in the periods preceding and following the hurricane appearance. For SS this disturbance gradually increase with the hurricane strength. A characteristic peak in the CR intensity appears before the hurricane start. But its place varies between 5 and 20 days before that start. Specific changes were observed in the SS. For major hurricanes they begins sometimes more than 20 days in advance. The AP and the KP show series of bursts, spread over the whole period of 30 preceding days. The obtained results from the performed correlational analysis are enough interesting to motivate a further statistical analysis with more precise techniques: in particular a common periodicity of 30 years found in the number of tropical storms landing into Mexico, the averaged rotational wind velocity and the ACE must be studied in connection with the solar Hale cycle. Using coherence wavelet spectral analysis we present a comparative study between one terrestrial and one cosmophysical phenomena that presumable influence hurricanes development: African dust outbreaks versus cosmic rays for all North Atlantic tropical cyclones. It is shown that the cosmophysical influence cannot be considered as a negligible effect.

Geodesic Distance in Planar Graphs: An Integrable Approach  

E-Print Network (OSTI)

We discuss the enumeration of planar graphs using bijections with suitably decorated trees, which allow for keeping track of the geodesic distances between faces of the graph. The corresponding generating functions obey non-linear recursion relations on the geodesic distance. These are solved by use of stationary multi-soliton tau-functions of suitable reductions of the KP hierarchy. We obtain a unified formulation of the (multi-) critical continuum limit describing large graphs with marked points at large geodesic distances, and obtain integrable differential equations for the corresponding scaling functions. This provides a continuum formulation of two-dimensional quantum gravity, in terms of the geodesic distance.

Angular distribution of polarized spontaneous emissions and its effect on light extraction behavior in InGaN-based light emitting diodes  

SciTech Connect

Angular intensity distributions of differently polarized light sources in multiple quantum wells (MQWs) and their effects on extraction behavior of spontaneous emission from light emitting diode (LED) chips have been studied. Theoretical calculation based on kp approximation, ray tracing simulation and angular electroluminescence measurement were applied in this work. It is found that the electron-hole recombination in the InGaN MQWs produces a spherical distribution of an s-polarized source and a dumbbell-shaped p-polarized source. Light rays from different polarized sources experience different extraction processes, determining the polarization degree of electro-luminescence and extraction efficiency of LEDs.

Measurement of the fraction of tt production via gluon-gluon fusion in pp collisions at {radical}(s)=1.96 TeV  

SciTech Connect

We present a measurement of the ratio of the tt production cross section via gluon-gluon fusion to the total tt production cross section in pp collisions at {radical}(s)=1.96 TeV at the Tevatron. Using a data sample with an integrated luminosity of 955 pb{sup -1} recorded by the CDF II detector at Fermilab, we select events based on the tt decay to lepton+jets. Using an artificial neural network technique we discriminate between tt events produced via qq annihilation and gg fusion, and find G{sub f}={sigma}(gg{yields}tt)/{sigma}(pp{yields}tt)<0.33 at the 68% confidence level. This result is combined with a previous measurement to obtain the most stringent measurement of this quantity by CDF to date, G{sub f}=0.07{sub -0.07}{sup +0.15}.

Decadal growth of black carbon emissions in India - article no. L02807  

SciTech Connect

A Geographical Information System (GIS) based methodology has been used to construct the black carbon (BC) emission inventory for the Indian geographical region. The distribution of emissions from a broader level to a spatial resolution of 1{sup o} x 1{sup o} grid has been carried out by considering micro level details and activity data of fossil fuels and bio-fuels. Our calculated total BC emissions were 1343.78 Gg and 835.50 Gg for the base years 2001 and 1991 respectively with a decadal growth of around 61%, which is highly significant. The district level analysis shows a diverse spatial distribution with the top 10% emitting districts contributing nearly 50% of total BC emission. Coal contributes more than 50% of total BC emission. All the metropolitan cities show high BC emissions due to high population density giving rise to high vehicular emissions and more demand of energy.

From realistic 2HDM-II CPV benchmarks to the $H^\\pm \\to\\tau \  

E-Print Network (OSTI)

Phenomenological studies of a CP-violating two-Higgs-doublet Model with type-II Yukawa couplings are presented. In the light of recent LHC data, an update on the viable parameter space that survives both the experimental and theoretical constraints is provided. In addition, the scope of the LHC in exploring this model through the discovery of a charged Higgs boson that decays in the tauonic mode is analysed. For this, various production channels were investigated, with emphasis on the boson-associated channel $gg\\to H_i\\to H^\\pm W^\\mp$ and the fermion-associated channels $gb\\to H^\\pm t$ and $gg\\to H^\\pm bt$. For the latter, a signal-over-background analysis is performed.

In both cases the magnetic energy grows at small scale and saturates as an inverse `` cascade ''.

Evaluation of Preindustrial to Present-day Black Carbon and its Albedo Forcing from Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP)  

SciTech Connect

As a part of the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP), we evaluate the historical black carbon (BC) aerosols simulated by 8 ACCMIP models against the observations including 12 ice core records, a long-term surface mass concentrations and recent Arctic BC snowpack measurements. We also estimate BC albedo forcing by performing additional simulations using the NCAR Community Land and Sea-Ice model 4 with prescribed meteorology from 1996-2000, which includes the SNICAR BC-snow model. We evaluated the vertical profile of BC snow concentrations from these offline simulations to using recent BC snowpack measurements. Despite using the same BC emissions, global BC burden differs by approximately a factor of 3 among models due to the differences in aerosol removal parameterizations and simulated meteorology among models; 34 Gg to 103 Gg in 1850 and 82 Gg to 315 Gg in 2000. However,models agree well on 2.5~3 times increase in the global BC burden from preindustrial to present-day, which matches with the 2.5 times increase in BC emissions. We find a large model diversity at both NH and SH high latitude regions for BC burden and at SH high latitude regions for deposition fluxes. The ACCMIP simulations match the observed BC mass concentrations well in Europe and North America except at Jungfrauch and Ispra. However, the models fail to capture the Arctic BC seasonality due tosevere underestimations during winter and spring. Compared to recent snowpack measurements, the simulated vertically resolved BC snow concentrations are, on average, within a factor of 2-3 of observations except for Greenland and Arctic Ocean. However, model and observation differ widely due to missing interannual variations in emissions and possibly due to the choice of the prescribed meteorology period (i.e., 1996-2000).

Light sfermion interplay in the 125 GeV MSSM Higgs production and decay at the LHC  

E-Print Network (OSTI)

We study the effects from light sfermions on the lightest Higgs boson production and decay at the Large Hadron Collider (LHC) within the Minimal Supersymmetric Standard Model (MSSM). We find that the scenario with light coloured sfermions -- stops or sbottoms -- has the potential to explain a non-universal alteration, as hinted by LHC data, of the gluon-gluon Fusion ($\\mu_{ggF}$) with respect to the Vector Boson Fusion ($\\mu_{VBF}$) event rates and, in particular, can predict $\\frac{\\mu_{VBF}}{\\mu_{ggF}}>1$ for all Higgs boson decay channels in large areas of the parameter space. We also find that the scenario with a light stop/sbottom can be complemented by the scenario in which the total Higgs width, $\\Gamma_{\\rm tot}$, is reduced due to a suppressed Yukawa coupling $Y_b$. In this case, the reduction of the Higgs production rates in the $ggF$ process which occurs in the maximal mixing scenario is compensated by the reduction of the $H\\to b\\bar{b}$ partial decay width, the largest component of $\\Gamma_{\\rm t...

Emission factor estimates of cereal waste burning in Spain  

Science Journals Connector (OSTI)

Every year more than 5 million ha of cereal fields are affected by fires in order to eliminate cereal waste in Spain. The characteristics of this type of fire with intense flames are similar to those of the African dry savanna heading fires. This paper surveys the atmospheric emission caused by this process by combining results of field and combustion chamber experiments. Combustion chamber experiments show that during the flaming phase 88% of the fire exposed carbon is converted into CO2 and during the smoldering phase this percentage changes to 74%. These combustion chamber experiments also show that the soluble part of the aerosols emitted during the course of fires only represent 3% of the total particulate matter (TPM) produced, being the ions K+ and CI? the predominant ones. The cereal waste fire process can be represented by an arithmetic combination that takes into account the amounts of mass burned during the two phases of the fire: 0.90 flaming +0.10 smoldering. Emission factor estimates from field burning experiment are 137g TPMkg?1(dm) and 2.80.2g NOxkg?1 (dm). Finally, we obtain average emissions of 80130Gg TPM, 1728Gg NOx, 210350Gg CO and 814Tg CO2 in Spain. These emissions represent nearly 25% of the total \\{NOx\\} and 50% of the total CO2 emissions by other pollution sources during the burning period in Spain.

Pollution by cereal waste burning in Spain  

Science Journals Connector (OSTI)

In this paper, the amount of cereal waste burned in Spain, which represents the most important source of biomass burning in this country, is estimated. During the period between 1980 and 1998, an average mass of 8 Tg of cereal waste was burned annually, with remaining 1 Tg of ash on the cereal fields after combustion. By using emission factors previously calculated by Ortiz de Zrate et al. [Ortiz de Zrate, I., Ezcurra, A., Lacaux, J.P., Van Dihn, P., 2000. Emission factor estimates of cereal waste burning in Spain. Atmos. Environ. 34, 31833193.], it is deduced that pollutant emissions linked to cereal waste-burning process reach values of 11 Tg CO2, 80 Gg of TPM and 23 Gg of \\{NOx\\} year?1 during the cereal-burning period. These emissions represent 46% of total CO2 and 23% \\{NOx\\} emitted in Spain during the burning period that lasts 1 month after harvesting. Therefore, the relative importance of cereal waste burning as pollutant source in Spain almost during fire period becomes evident. Finally, our study allows to deduce that the production of 1 kg of cereal crop implies that 410 g of carbon and 3.3 g of nitrogen are going to be introduced into the atmosphere by this pollutant process. We estimate a total gaseous emission of 3.3 Tg of C and 25 Gg N as different pollutants by cereal waste burning.

Region-based quantitative and hierarchical attribute reduction in the two-category decision theoretic rough set model  

Science Journals Connector (OSTI)

Abstract Quantitative attribute reduction exhibits applicability but complexity when compared to qualitative reduction. According to the two-category decision theoretic rough set model, this paper mainly investigates quantitative reducts and their hierarchies (with qualitative reducts) from a regional perspective. (1) An improved type of classification regions is proposed, and its preservation reduct (CRP-Reduct) is studied. (2) Reduction targets and preservation properties of set regions are analyzed, and the set-region preservation reduct (SRP-Reduct) is studied. (3) Separability of set regions and rule consistency is verified, and the quantitative and qualitative double-preservation reduct (DP-Reduct) is established. (4) Hierarchies of CRP-Reduct, SRP-Reduct, and DP-Reduct are explored with two qualitative reducts: the Pawlak-Reduct and knowledge-preservation reduct (KP-Reduct). (5) Finally, verification experiments are provided. CRP-Reduct, SRP-Reduct, and DP-Reduct expand layer by layer Pawlak-Reduct and exhibit quantitative applicability, and the experimental results indicate their effectiveness and hierarchies regarding Pawlak-Reduct and KP-Reduct.

Theoretical studies of optical gain tuning by hydrostatic pressure in GaInNAs/GaAs quantum wells  

SciTech Connect

In order to describe theoretically the tuning of the optical gain by hydrostatic pressure in GaInNAs/GaAs quantum wells (QWs), the optical gain calculations within kp approach were developed and applied for N-containing and N-free QWs. The electronic band structure and the optical gain for GaInNAs/GaAs QW were calculated within the 10-band kp model which takes into account the interaction of electron levels in the QW with the nitrogen resonant level in GaInNAs. It has been shown that this interaction increases with the hydrostatic pressure and as a result the optical gain for GaInNAs/GaAs QW decreases by about 40% and 80% for transverse electric and transverse magnetic modes, respectively, for the hydrostatic pressure change from 0 to 40 kilobars. Such an effect is not observed for N-free QWs where the dispersion of electron and hole energies remains unchanged with the hydrostatic pressure. This is due to the fact that the conduction and valence band potentials in GaInAs/GaAs QW scale linearly with the hydrostatic pressure.

Commuting flows and conservation laws for noncommutative Lax hierarchies  

SciTech Connect

We discuss commuting flows and conservation laws for Lax hierarchies on noncommutative spaces in the framework of the Sato theory. On commutative spaces, the Sato theory has revealed essential aspects of the integrability for wide class of soliton equations which are derived from the Lax hierarchies in terms of pseudodifferential operators. Noncommutative extension of the Sato theory has been already studied by the author and Toda, and the existence of various noncommutative Lax hierarchies are guaranteed. In this paper, we present conservation laws for the noncommutative Lax hierarchies with both space-space and space-time noncommutativities and prove the existence of infinite number of conserved densities. We also give the explicit representations of them in terms of Lax operators. Our results include noncommutative versions of KP, KdV, Boussinesq, coupled KdV, Sawada-Kotera, modified KdV equation and so on.

Band gap tuning and optical absorption in type-II InAs/GaSb mid infrared short period superlattices: 14 bands K Dot-Operator p study  

SciTech Connect

The MBE growth of short-period InAs/GaSb type-II superlattice structures, varied around 20.5 A InAs/24 A GaSb were [J. Applied physics, 96, 2580 (2004)] carried out by Haugan et al. These SLs were designed to produce devices with an optimum mid-infrared photoresponse and a sharpest photoresponse cutoff. We have used a realistic and reliable 14-band k.p formalism description of the superlattice electronic band structure to calculate the absorption coefficient in such short-period InAs/GaSb type-II superlattices. The parameters for this formalism are known from fitting to independent experiments for the bulk materials. The band-gap energies are obtained without any fitting parameters, and are in good agreement with experimental data.

Training Hybrid Neuro-Fuzzy System to Infer Permeability in Wells on Maracaibo Lake, Venezuela  

E-Print Network (OSTI)

The high accuracy on inferrring of rocks properties, such as permeability ($k$), is a very useful study in the analysis of wells. This has led to development and use of empirical equations like Tixier, Timur, among others. In order to improve the inference of permeability we used a hybrid Neuro-Fuzzy System (NFS). The NFS allowed us to infer permeability of well, from data of porosity ($\\phi$) and water saturation ($Sw$). The work was performed with data from wells VCL-1021 (P21) and VCL-950 (P50), Block III, Maracaibo Lake, Venezuela. We evaluated the NFS equations ($k_{P50,i}(\\phi_i,Sw_i)$) with neighboring well data ($P21$), in order to verify the validity of the equations in the area. We have used ANFIS in MatLab.

This report is devoted to deriving a number of discrete models, including well-known integrable systems such as the KdV, KP, Toda, BKP, CKP, and special Viallet equations, from `nothing' via simple principles. It is conjectured that the discrete models generated from nothing may be integrable because they are identities of simple algebra, model-independent nonlinear superpositions of a trivial integrable system (Riccati equation), index homogeneous decompositions of the simplest geometric theorem (the angle bisector theorem), as well as the M\\"obious transformation invariants.

Exchange interaction and rashba spin splitting effects in electron spin resonance in narrow-gap quantum wells  

SciTech Connect

We report a study of electron spin resonance (ESR) in a perpendicular magnetic field in n-type narrow-gap quantum well (QW) heterostructures. Using the Hartree-Fock approximation, based on the 88 k?p Hamiltonian, the many-body corrections to the ESR energy are found to be nonzero in symmetric and asymmetric narrow-gap QWs. We demonstrate a significant enhancement of the ESR energy in asymmetric QWs, induced by the Rashba spin splitting and exchange interaction, as well as the exchange-induced enhancement of the ESR energy in symmetric QWs. The ESR energies estimated for 2DEG in InAs/AlSb QWs are compared with experimental results in weak magnetic fields.

Kaon Absorption from Kaonic Atoms and Formation Spectra of Kaonic Nuclei  

E-Print Network (OSTI)

We considered the kaon absorption from atomic states into nucleus. We found that the nuclear density probed by the atomic kaon significantly depends on the kaon orbit. Then, we reexamined the meanings of the observed strengths of one-body and two-body kaon absorption, and investigated the effects to the formation spectra of kaon bound states by in-flight ($K^-,p$) reactions. As a natural consequence, if the atomic kaon probes the smaller nuclear density, the ratio of the two-body absorption at nuclear center is larger than the observed value, and the depth of the imaginary potential is deeper even at smaller kaon energies as in kaonic nuclear states because of the large phase space for the two-body processes.

Energy dependence of $\\bar{K}N$ interaction in nuclear medium  

E-Print Network (OSTI)

When the $\\bar{K}N$ system is submerged in nuclear medium the $\\bar{K}N$ scattering amplitude and the final state branching ratios exhibit a strong energy dependence when going to energies below the $\\bar{K}N$ threshold. A sharp increase of $\\bar{K}N$ attraction below the $\\bar{K}N$ threshold provides a link between shallow $\\bar{K}$-nuclear potentials based on the chiral $\\bar{K}N$ amplitude evaluated at threshold and the deep phenomenological optical potentials obtained in fits to kaonic atoms data. We show the energy dependence of the in-medium $K^{-}p$ amplitude and demonstrate the impact of energy dependent branching ratios on the $\\Lambda$-hypernuclear production rates. \\keywords{kaon-nucleon amplitude \\and nuclear medium \\and hypernuclei

Structural investigations of platinum anticancer drugs with DNA  

SciTech Connect

The antitumor agent cis-diamminedichloroplatinum (II) (cis-DDP) can successfully treat testicular and ovarian cancers, presumably by binding to DNA and preventing replication. cis-DDP is less successful in treating lung and breast cancers and the trans isomer is inactive. It has been suggested that cellular recognition and repair processes may be responsible for the difference in activity between cis- and trans-DDP, the differential effectiveness against different types of cancers, as well as acquired resistance. The author reviews structural methods used to characterize several site-specific adducts. Structure-function relations that emerge may help clarify the mechanism of action. The extent of DNA bending caused by several site-specific DNA adducts formed by cis- and trans-DDP has been determined using a gel electrophoresis assay. The adducts cis-GG, cis-AG, cis-GTG, and trans-GTG were incorporated into synthetic DNA oligonucleotides of varying lengths with two bp cohesive ends. Subtle DNA distortions were amplified by polymerizing these monomers and quantitated using polyacrylamide gel electrophoresis. The three adducts cis-GG, cis-AG, and cis-GTG were all found to bend the helix in a directed fashion by about 32-35[degrees]. The trans-GTG adduct gave a degree of flexibility to the double helix, allowing bending in more than one direction. The DNA unwinding caused by the platinum binding was measured by systematically varying the interplatinum distance in a series of synthetic DNA oligonucleotides. The cis-GG and cis-AG adducts both unwind the double helix by 13[degrees]C, while the cis-GTG adduct unwinds by 23[degrees]. To determine the complete structure of platinated duplex DNA< single crystals of a platinated 12 base pair duplex oligonucletide were obtained. Despite extreme temperature and radiation sensitivity problems, a complete set of data was collected. Several different approaches to solve the structure were attempted.

Electromagnetically induced transparency and dark fluorescence in a cascade three-level diatomic lithium system  

Science Journals Connector (OSTI)

Following our previous brief report [Phys. Rev. Lett. 88, 173003 (2002)], we report here a detailed study of electromagnetically induced transparency (EIT) and dark fluorescence in a cascade three-level diatomic lithium system using optical-optical double resonance (OODR) spectroscopy for both resonance and off resonance coupling. When a strong coupling laser couples the intermediate state A?u+1(v=13,J=14) to the upper state G?g1(v=11,J=14) of Li27, the fluorescence from both A?u+1 and G?g1 states was drastically reduced as the weak probe laser was tuned through the resonance transition between the ground state X?g+1(v=4,J=15) and the excited state A?u+1(v=13,J=14). The strong coupling laser makes an optically thick medium transparent for the probe transition. In addition, the fact that fluorescence from the upper state G?g1(v=11,J=14) was also dark when both lasers were tuned at resonance implies that the molecules were trapped in the ground state. We used density matrix methods to simulate the response of an open molecular three-level system to the action of a strong coupling field and a weak probe field. The analytical solutions were obtained under the steady-state condition. We have incorporated the magnetic sublevel (M) degeneracy of the rotational levels in the line shape analysis and report ?M? dependent line shape splitting. Our theoretical calculations are in excellent agreement with the observed fluorescence spectra. We show that the coherence is remarkably preserved even when the coupling field was detuned far from the resonance.

Nonlinear waves in strongly interacting relativistic fluids  

E-Print Network (OSTI)

During the past decades the study of strongly interacting fluids experienced a tremendous progress. In the relativistic heavy ion accelerators, specially the RHIC and LHC colliders, it became possible to study not only fluids made of hadronic matter but also fluids of quarks and gluons. Part of the physics program of these machines is the observation of waves in this strongly interacting medium. From the theoretical point of view, these waves are often treated with li-nearized hydrodynamics. In this text we review the attempts to go beyond linearization. We show how to use the Reductive Perturbation Method to expand the equations of (ideal and viscous) relativistic hydrodynamics to obtain nonlinear wave equations. These nonlinear wave equations govern the evolution of energy density perturbations (in hot quark gluon plasma) or baryon density perturbations (in cold quark gluon plasma and nuclear matter). Different nonlinear wave equations, such as the breaking wave, Korteweg-de Vries and Burgers equations, are obtained from different equations of state (EOS). In nuclear matter, the Walecka EOS may lead to a KdV equation. We explore equations of state such as those extracted from the MIT Bag Model and from QCD in the mean field theory approach. Some of these equations are integrable and have analytical solitonic solutions. We derive these equations also in spherical and cylindrical coordinates. We extend the analysis to two and three dimensions to obtain the Kadomtsev-Petviashvili (KP) equation, which is the generalization of the KdV. The KP is also integrable and presents analytical solitonic solutions. In viscous relativistic hydrodynamics we have second order patial derivatives which physically represent dissipation terms. We present numerical solutions and their corresponding algorithms for the cases where the equations are not integrable.

Formation spectra of light kaonic nuclei by in-flight (K,N) reactions with a chiral unitary amplitude  

Science Journals Connector (OSTI)

We study theoretically the in-flight (K-,N) reactions for the formation of light kaonic nuclear systems to get deeper physical insights on the spectra and to investigate the formation spectra of the reaction that will be observed at new facilities like the Japan Proton Accelerator Research Complex (J-PARC). We show the expected spectra for the formation of the K-pp, K-pn, K-nn, and K--B11 systems that are accessible by the (K-,N) experiments. By considering the conversion part of the Greens function, we show the missing mass spectra of the (K-,N) reactions in coincident with the particle emissions due to K absorption. To calculate the cross sections, we use the so-called T? approximation to evaluate the optical potential. As for the amplitude T, we adopt the chiral unitary amplitude of KN channel in vacuum for simplicity. The effects of the p-wave optical potential of ?(1385) channel and the contributions from K0 mixing in He3(K-,n) reaction are also evaluated numerically. We also study the behavior of the poles of kaon Greens function in nuclear matter. We conclude that He3(K-,n) and He3(K-,p) reaction spectra in coincident with the ?? emission may show the structure in the kaon bound region indicating the existence of the unstable kaonic nuclear states. As for the C12(K-,p) spectra with the ?? emission, we may also observe the structure in the bound region, however, we need to evaluate the medium effects carefully for larger nuclei.

Two Dimensional Renormalization Group Flows in Next to Leading Order  

E-Print Network (OSTI)

Zamolodchikov's famous analysis of the RG trajectory connecting successive minimal CFT models $M_p$ and $M_{p-1}$ for $p\\gg 1$, is improved by including second order in coupling constant corrections. This allows to compute IR quantities with next to leading order accuracy of the $1/p$ expansion. We compute in particular, the beta function and the anomalous dimensions for certain classes of fields. As a result we are able to identify with a greater accuracy the IR limit of these fields with certain linear combination of the IR theory $M_{p-1}$. We discuss the relation of these results with Gaotto's recent RG domain wall proposal.

Automating dipole subtraction  

E-Print Network (OSTI)

We report on automating the Catani-Seymour dipole subtraction which is a general procedure to treat infrared divergences in real emission processes at next-to-leading order in QCD. The automatization rests on three essential steps: the creation of the dipole terms, the calculation of the color linked squared Born matrix elements, and the evaluation of different helicity amplitudes. The routines have been tested for a number of complex processes, such as the real emission process gg --> t anti-t ggg.

Atmospheric and Solar neutrinos in the light of the SuperKamiokande results  

E-Print Network (OSTI)

The hierarchy $\\Delta m^2_{atm} \\gg \\Delta m^2_\\odot$ and the large $\\theta_{23}$ mixing angle, as suggested by neutrino oscillation experiments, can be accounted for by a variety of lepton flavour models. A dichotomy emerges: i) Models were all neutrino masses are bounded by $m_{atm}\\equiv (\\Delta m^2_{atm})^{1/2}\\approx 0.03 eV$; ii) Models of quasi-degenerate neutrinos. It is shown how these different patterns of neutrino masses may arise from different lepton flavour symmetries. Physical implications are discussed in the various cases.

A SEARCH FOR L/T TRANSITION DWARFS WITH Pan-STARRS1 AND WISE: DISCOVERY OF SEVEN NEARBY OBJECTS INCLUDING TWO CANDIDATE SPECTROSCOPIC VARIABLES  

SciTech Connect

We present initial results from a wide-field (30,000 deg{sup 2}) search for L/T transition brown dwarfs within 25 pc using the Pan-STARRS1 and Wide-field Infrared Survey Explorer (WISE) surveys. Previous large-area searches have been incomplete for L/T transition dwarfs, because these objects are faint in optical bands and have near-infrared (near-IR) colors that are difficult to distinguish from background stars. To overcome these obstacles, we have cross-matched the Pan-STARRS1 (optical) and WISE (mid-IR) catalogs to produce a unique multi-wavelength database for finding ultracool dwarfs. As part of our initial discoveries, we have identified seven brown dwarfs in the L/T transition within 9-15 pc of the Sun. The L9.5 dwarf PSO J140.2308+45.6487 and the T1.5 dwarf PSO J307.6784+07.8263 (both independently discovered by Mace et al.) show possible spectroscopic variability at the Y and J bands. Two more objects in our sample show evidence of photometric J-band variability, and two others are candidate unresolved binaries based on their spectra. We expect our full search to yield a well-defined, volume-limited sample of L/T transition dwarfs that will include many new targets for study of this complex regime. PSO J307.6784+07.8263 in particular may be an excellent candidate for in-depth study of variability, given its brightness (J = 14.2 mag) and proximity (11 pc)

Distribution of rare earth elements in marine sediments from the Strait of Sicily (western Mediterranean Sea): Evidence of phosphogypsum waste contamination  

Science Journals Connector (OSTI)

Concentrations of rare earth elements (REE), Y, Th and Sc were recently determined in marine sediments collected using a box corer along two onshoreoffshore transects located in the Strait of Sicily (Mediterranean Sea). The REE+Y were enriched in offshore fine-grained sediments where clay minerals are abundant, whereas the REE+Y contents were lower in onshore coarse-grained sediments with high carbonate fractions. Considering this distribution trend, the onshore sediments in front of the southwestern Sicilian coast represent an anomaly with high REE+Y concentrations (mean value 163.4?gg?1) associated to high Th concentrations (mean value 7.9?gg?1). Plot of shale-normalized REE+Y data of these coastal sediments showed Middle REE enrichments relative to Light REE and Heavy REE, manifested by a convexity around SmGdEu elements. These anomalies in the fractionation patterns of the coastal sediments were attributed to phosphogypsum-contaminated effluents from an industrial plant, located in the southern Sicilian coast.

Comparison between continuous stirred tank reactor extractor and soxhlet extractor for extraction of El-Lajjun oil shale  

SciTech Connect

Extraction on El-Lajjun oil shale in a continuous stirred tank reactor extractor (CSTRE) and a Soxhlet extractor was carried out using toluene and chloroform as solvents. Solvents were recovered using two distillation stages, a simple distillation followed by a fractional distillation. Gas chromotography was used to test for the existence of trapped solvent in the yield. It was found that extraction using a CSTRE gave a 12% increase in yield on average compared with the Soxhlet extractor, and an optimum shale size of 1.0mm offered a better yield and solvent recovery for both techniques. It was also found that an optimum ratio of solvent to oil shale of 2:1 gave the best oil yield. The Soxhlet extractor was found to offer an extraction rate of 1 hour to complete extraction compared with 4 hours in a CSTRE. The yield in a CSTRE was found to increase on increase of stirring. When extraction was carried out at the boiling point of the solvents in a CSTRE, the yield was found to increase by 30% on average compared to that of extraction when the solvent was at room temperature. When toluene was used for extraction, the average amount of bitumen extracted was 0.032 g/g of oil shale and 76.4% of the solvent recovered, compared with 0.037 g/g of oil shale and 84.1% of the solvent recovered using a Soxhlet extractor.

The connection between 2006 IPCC GHG inventory methodology and ISO 14064-1 certification standard A reference point for the environmental policies at sub-national scale  

Science Journals Connector (OSTI)

Abstract The article shows how a joint application of the 2006 IPCC methodology and the ISO 14064-1 standard of certification, as well as the co-operation between academic, legislative and administrative organizations, are important points for a sustainable management of an administrative jurisdiction, providing positive environmental effects. The administrative systems can choose validated ISO 14064-1 GHG inventories, produced in time series, as a strategy tool for local management, as a compass to orient future policy decisions. The Province of Siena (Tuscany, Central Italy) was one regional system in Europe to achieve the ISO 14064-1 certification of its GHG inventories, developed in time series applying the 2006 IPCC methodology. The results of the time series (year 20062010) of GHG inventories elaborated for the Province of Siena point out that the performed environmental management policies may bring about a significant reduction of GHG emission released to the atmosphere over time (net emission: 449GgCO2eq in 2006, 84GgCO2eq in 2010). The experience of the Province of Siena can be considered a significant reference model for all public authorities at the micro and macro scale who are interested in reducing GHG emission.

AlFe PILC preparation, characterization and its potential adsorption capacity for aflatoxin B1  

Science Journals Connector (OSTI)

Abstract Montmorillonite (Mt) was used as the precursor material for synthesis of aluminumironpillared montmorillonite (AlFePMt) and the adsorption of aflatoxin B1 (AFB1) by Mt and AlFePMt was investigated. Different forms of polycations were prepared and used to modify Mt, when the molar ratio of Al3+ to Fe3+ was 8.0, AlFePMt obtained the maximum adsorption capacity of AFB1 (660.0?g/g) which was much higher than that of Mt (30.4?g/g). The adsorbents were characterized by XRD, SEM and FTIR, and the effects of adsorbent amount, pH and interaction time on the adsorption of AFB1 onto Mt and AlFePMt were also studied. Adsorption isotherm parameters were obtained from Langmuir and Freundlich and the adsorption data fitted better to Langmuir. The obtained results show that the great difference of adsorption capacity between Mt and AlFePMt mainly lies in their microstructure and chemical composition, and it suggests that AlFePMt is suitable to be used as a potential adsorbent to remove AFB1 from the contaminated products.

Production of single top-quark final states at the LHC from supersymmetric FCNC interactions  

E-Print Network (OSTI)

We discuss the production of single top-quark final states by direct supersymmetric flavor-changing interactions at the LHC. The total cross section pp(gg)->t\\bar{c}+\\bar{t}c is computed at the 1-loop order within the unconstrained MSSM. We prove that SUSY-QCD effects may furnish sizeable production rates amounting up to barely 10^5 t\\bar{c}(c\\bar{t}) events per 100 fb^{-1} of integrated luminosity, in full compliance with the stringent low-energy constraints from b->s gamma. Furthermore, we show that the cooperative SUSY-EW effects can be sizeable on their own, regardless of the SUSY-QCD contribution, with maximum production rates of the order of 10^3 events per 100 fb^{-1}. Owing to the fact that FCNC production of electrically neutral heavy-quark pairs is virtually absent within the SM, we conclude that the observation of such pp(gg)->t\\bar{c}+\\bar{t}c processes at the LHC could lead to evidence of new physics - of likely supersymmetric nature.

Relationship between selenium body burdens and tissue concentrations in fish exposed to coal ash at the Tennessee Valley Authority Kingston spill site  

SciTech Connect

In December 2008, 4.1 million m3 of coal ash were released into the Emory and Clinch Rivers by the Tennessee Valley Authority (TVA) Kingston Fossil Plant. Coal ash contains several contaminants, including the bioaccumulative metalloid selenium (Se). Because Se is predominantly accumulated in aquatic organisms through dietary, rather than aqueous exposure, tissue-based toxicity thresholds for Se are currently being considered. The proposed threshold concentrations range between 4-9 g/g Se (dry wt.) in whole body fish, with a proposed fillet threshold of 11.8 g/g. In the present study we examined the spatial and temporal trends in Se bioaccumulation and examined the relationship between the Se content in fillets and in whole bodies of fish collected around the Kingston spill site to determine whether Se bioaccumulation was a significant concern at the ash spill site. While Se concentrations in fish (whole bodies and fillets) were elevated at sampling locations affected by the Kingston ash spill relative to reference locations, concentrations do not appear to be above risk thresholds and have not been increasing over the five year period since the spill. Our results are not only relevant to guiding the human health and ecological risk assessments at the Kingston ash spill site, but because of current national discussions on appropriate guidelines for Se in fish as well for the disposal of coal combustion wastes, our results are also relevant to the general understanding of Se bioaccumulation in contaminated water bodies.

Projection and Galaxy Clustering Fourier Spectra  

E-Print Network (OSTI)

Second order perturbation theory predicts a specific dependence of the bispectrum, or three-point correlation function in the Fourier transform domain, on the shape of the configuration of its three wave vector arguments, which can be taken as a signature of structure formed by gravitational instability. Comparing this known dependence on configuration shape with the weak shape dependence of the galaxy bispectrum has been suggested as an indication of bias in the galaxy distribution. However, to interpret results obtained from projected catalogs, we must first understand the effects of projection on this shape dependence. We present expressions for the projected power spectrum and bispectrum in both Cartesian and spherical geometries, and we examine the effects of projection on the predicted bispectrum with particular attention to the dependence on configuration shape. Except for an overall numerical factor, for Cartesian projection with characteristic depth $ \\Dstar $ there is little effect on the shape dependence of the bispectrum for wavelengths small compared to $ \\Dstar $ or projected wavenumbers $ q \\Dstar \\gg 1 $. For angular projection, a scaling law is found for spherical harmonic index $ \\ell \\gg 1 $, but there is always a mixing of scales over the range of the selection function. For large $ \\ell $ it is sufficient to examine a small portion of the sky.

Variable Speed of Light Cosmology, Primordial Fluctuations and Gravitational Waves  

E-Print Network (OSTI)

A variable speed of light (VSL) cosmology is developed with a spontaneous breaking of Lorentz invariance in the early universe. A non-minimal electromagnetic coupling to curvature and the resulting quantum electrodynamic vacuum polarization dispersive medium can produce $c\\gg c_0$ in the early universe, where $c_0$ is the measured speed of light today. Higher derivative curvature contributions to the effective gravitational action and quantum gravity vacuum polarization can produce a dispersive medium and a large increase in the speed of gravitational waves $c_g\\gg c_{g0}$ in the early universe, where $c_{g0}$ is the speed of gravitational waves today. The initial value problems of cosmology are solved: the horizon and flatness problems. The model predicts primordial scalar and tensor fluctuation spectral indices $n_s=0.96$ and $n_t=- 0.04$, respectively. The BICEP2 observation of $r=0.2$ yields $r/n_t=-5$ which is close to the single-field inflationary consistency condition $r/n_t=-8$.

The distribution of depleted uranium contamination in Colonie, NY, USA  

Science Journals Connector (OSTI)

Uranium oxide particles were dispersed into the environment from a factory in Colonie (NY, USA) by prevailing winds during the 1960s and '70s. Uranium concentrations and isotope ratios from bulk soil samples have been accurately measured using inductively coupled plasma quadrupole mass spectrometry (ICP-QMS) without the need for analyte separation chemistry. The natural range of uranium concentrations in the Colonie soils has been estimated as 0.72.1?gg?1, with a weighted geometric mean of 1.05?gg?1; the contaminated soil samples comprise uranium up to 50040?gg?1. A plot of 236U/238U against 235U/238U isotope ratios describes a mixing line between natural uranium and depleted uranium (DU) in bulk soil samples; scatter from this line can be accounted for by heterogeneity in the DU particulate. The end-member of DU compositions aggregated in these bulk samples comprises (2.050.06)נ10?3 235U/238U, (3.20.1)נ10?5 236U/238U, and (7.10.3)נ10?6 234U/238U. The analytical method is sensitive to as little as 50ngg?1 DU mixed with the natural uranium occurring in these soils. The contamination footprint has been mapped northward from site, and at least one third of the uranium in a soil sample from the surface 5cm, collected 5.1km NNW of the site, is DU. The distribution of contamination within the surface soil horizon follows a trend of exponential decrease with depth, which can be approximated by a simple diffusion model. Bioturbation by earthworms can account for dispersal of contaminant from the soil surface, in the form of primary uranium oxide particulates, and uranyl species that are adsorbed to organic matter. Considering this distribution, the total mass of uranium contamination emitted from the factory is estimated to be c. 4.8tonnes.

Study of Multi-Scale Cloud Processes Over the Tropical Western Pacific Using Cloud-Resolving Models Constrained by Satellite Data  

SciTech Connect

Clouds in the tropical western Pacific are an integral part of the large scale environment. An improved understanding of the multi-scale structure of clouds and their interactions with the environment is critical to the ARM (Atmospheric Radiation Measurement) program for developing and evaluating cloud parameterizations, understanding the consequences of model biases, and providing a context for interpreting the observational data collected over the ARM Tropical Western Pacific (TWP) sites. Three-dimensional cloud resolving models (CRMs) are powerful tools for developing and evaluating cloud parameterizations. However, a significant challenge in using CRMs in the TWP is that the region lacks conventional data, so large uncertainty exists in defining the large-scale environment for clouds. This project links several aspects of the ARM program, from measurements to providing improved analyses, and from cloud-resolving modeling to climate-scale modeling and parameterization development, with the overall objective to improve the representations of clouds in climate models and to simulate and quantify resolved cloud effects on the large-scale environment. Our objectives will be achieved through a series of tasks focusing on the use of the Weather Research and Forecasting (WRF) model and ARM data. Our approach includes: -- Perform assimilation of COSMIC GPS radio occultation and other satellites products using the WRF Ensemble Kalman Filter assimilation system to represent the tropical large-scale environment at 36 km grid resolution. This high-resolution analysis can be used by the community to derive forcing products for single-column models or cloud-resolving models. -- Perform cloud-resolving simulations using WRF and its nesting capabilities, driven by the improved regional analysis and evaluate the simulations against ARM datasets such as from TWP-ICE to optimize the microphysics parameters for this region. A cirrus study (Mace and co-authors) already exists for TWP-ICE using satellite and ground-based observations. -- Perform numerical experiments using WRF to investigate how convection over tropical islands in the Maritime Continent interacts with large-scale circulation and affects convection in nearby regions. -- Evaluate and apply WRF as a testbed for GCM cloud parameterizations, utilizing the ability of WRF to run on multiple scales (from cloud resolving to global) to isolate resolution and physics issues from dynamical and model framework issues. Key products will be disseminated to the ARM and larger community through distribution of data archives, including model outputs from the data assimilation products and cloud resolving simulations, and publications.

OECD MCCI project Small-Scale Water Ingression and Crust Strength Tests (SSWICS) SSWICS-1 test data report : thermal hydraulic results. Rev. 0 September 20, 2002.  

SciTech Connect

The Melt Attack and Coolability Experiments (MACE) program at Argonne National Laboratory addressed the issue of the ability of water to cool and thermally stabilize a molten core/concrete interaction (MCCI) when the reactants are flooded from above. These tests provided data regarding the nature of corium interactions with concrete, the heat transfer rates from the melt to the overlying water pool, and the role of noncondensable gases in the mixing processes that contribute to melt quenching. However, due to the integral nature of these tests, several questions regarding the crust freezing behavior could not be adequately resolved. These questions include: (1) To what extent does water ingression into the crust increase the melt quench rate above the conduction-limited rate and how is this affected by melt composition and system pressure and (2) What is the fracture strength of the corium crust when subjected to a thermal-mechanical load and how does it depend upon the melt composition? A series of separate-effects experiments are being conducted to address these issues. The first employs an apparatus designed to measure the quench rate of a pool of corium ({approx}{phi}30 cm; up to 20 cm deep). The main parameter to be varied in these quench tests is the melt composition since it is thought to have a critical influence on the crust cracking behavior which, in turn, alters quench rate. The issue of crust strength will be addressed with a second apparatus designed to mechanically load the crust produced by the quench tests. This apparatus will measure the fracture strength of the crust while under a thermal load created by a heating element beneath the crust. The two apparatuses used to measure the melt quench rate and crust strength are jointly referred to as SSWICS (Small-Scale Water Ingression and Crust Strength). This report describes results of the first water ingression test, designated SSWICS-1. The report includes a description of the test apparatus, the instrumentation used, plots of the recorded data, and some rudimentary data reduction to obtain an estimate of the heat flux from the corium to the overlying water pool.

These 6 layer magnets were designed to include the main quadrupole focus, a skew quad, a normal and skew dipole, and a final sextupole layer. Because of the physical space constraints imposed by the existing detector region components, the DESY magnets were of necessity designed to be very compact. In addition, they are also are required to operate within the solenoidal detector fields at the collision points, so all construction materials had to be non magnetic. Two types of DESY magnets were fabricated. The first, designated as G0, was a two meter long, constant radius magnet. The second, designated GG, is a

The tool consists of an ultrasonic transducer coupled with a downhole inclinometer. These devices are used to generate an oriented image of seismic velocity variation and wave amplitude. These images are then examined and highlighted to reveal fractures, bedding planes and orientation of those features. The log is useful for strata and fracture delineation, and can also be used to evaluate compressional-wave velocity, borehole deviation and eccentricity.[1] References ↑ http://www.dot.ca.gov/hq/esc/geotech/gg/atv_log.htm Ret LikeLike UnlikeLike You like this.Sign Up to see what your friends like.

Determination of Boron-Containing Compounds in Urine and Blood Plasma from Boron Neutron Capture Therapy Patients. The Importance of Using Coupled Techniques  

Science Journals Connector (OSTI)

Since only 10B (comprising 20% of elemental boron in nature) has the large cross-section for neutron capture reaction and is thereby useful for BNCT, the boron in the BPA transport molecules used in the Studsvik therapy was enriched with the 10B isotope to nearly 100%. ... A 1000 ?g/mL certified boric acid standard was purchased from BDH Chemicals (Poole, U.K.) and diluted to 2?10 ppm (?g/g) of boron in 0.1 M hydrochloric acid. ...

In situ global method for measurement of oxygen demand and mass transfer  

SciTech Connect

Two aerobic microorganisms, Saccharomycopsis lipolytica and Brevibacterium lactofermentum, have been used in a study of mass transfer and oxygen uptake from a global perspective using a closed gas system. Oxygen concentrations in the gas and liquid were followed using oxygen electrodes, and the results allowed for easy calculation of in situ oxygen transport. The cell yields on oxygen for S. lipolytica and B. lactofermentum were 1.01 and 1.53 g/g respectively. The mass transfer coefficient was estimated as 10 h{sup {minus}1} at 500 rpm for both fermentations. The advantages with this method are noticeable since the use of model systems may be avoided, and the in situ measurements of oxygen demand assure reliable data for scale-up.

Borexino: A real time liquid scintillator detector for low energy solar neutrino study  

E-Print Network (OSTI)

Borexino is a large unsegmented calorimeter featuring 300 tons of liquid scintillator, contained in a 8.5 meter nylon vessel, viewed by 2200 PMTs. The main goal of Borexino is the study, in real time, of low energy solar neutrinos, and in particular, the monoenergetic neutrinos coming from $^7Be$, which is one of the missing links on the solar neutrino problem. The achievement of high radiopurity level, in the order of $10^{-16} g/g$ of U/Th equivalent, necessary to the detection of the low energy component of the solar neutrino flux, was proved in the Borexino prototype: the Counting Test Facility. The detector is located underground in the Laboratori Nazionali del Gran Sasso in the center of Italy at 3500 meter water equivalent depth. In this paper the science and technology of Borexino are reviewed and its main capabilities are presented.

Parton distribution function dependence of benchmark Standard Model total cross sections at the 7 TeV LHC

In particular, we focus on the dependence on the different values of the strong coupling, alpha_S(M_Z^2), used by each group. We also perform a comparison of the relevant quark-antiquark and gluon-gluon luminosity functions. We make some comments on the recent PDF4LHC recommendations. Finally, we discuss the comparison of data and theory for W and Z cross sections at the LHC.

Gluon Fusion Contribution to $VHj$ Production at Hadron Colliders  

E-Print Network (OSTI)

We study the associated production of an electroweak vector boson and the Higgs boson with a jet via gluon-gluon fusion. At the leading order, these processes occur at one-loop level. The amplitudes of these one-loop processes are gauge invariant and finite. Therefore, their contributions towards the corresponding hadronic cross sections and kinematic distributions can be calculated separately. We present results for the Large Hadron Collider and its discussed upgrades. We find that the gluon-gluon one-loop process gives dominant contribution to the $\\gamma H j$ production. We observe a destructive interference effect in the $gg\\to Z H j$ amplitude. We also find that in the high transverse momentum and central rapidity region, the $ZHj$ production cross section via gluon-gluon fusion becomes comparable to the cross section contributions coming from quark-quark and quark-gluon channels.

Matter power spectrum for the generalized Chaplygin gas model: The relativistic case  

E-Print Network (OSTI)

The generalized Chaplygin gas (GCG) model is the prototype of a unified model of dark energy (DE) and dark matter (DM). It is characterized by equation-of-state (EoS) parameters $A$ and $\\alpha$. We use a statistical analysis of the 2dFGRS data to constrain these parameters. In particular, we find that very small (close to zero) and very large values ($\\alpha\\gg 1$) of the equation-of-state parameter $\\alpha$ are preferred. To test the validity of this type of unification of the dark sector we admit the existence of a separate DM component in addition to the Chaplygin gas and calculate the probability distribution for the fractional contributions of both components to the total energy density. This analysis favors a model for which the Universe is nearly entirely made up of the separate DM component with an almost negligible Chaplygin gas part. This confirms the results of a previous Newtonian analysis.

Effects of macromolecular crowding on the collapse of biopolymers  

E-Print Network (OSTI)

Experiments show that macromolecular crowding modestly reduces the size of intrinsically disordered proteins (IDPs) even at volume fraction ($\\phi$) similar to that in the cytosol whereas DNA undergoes a coil-to-globule transition at very small $\\phi$. We show using a combination of scaling arguments and simulations that the polymer size $\\overline{R}_g(\\phi)$ depends on $x = \\overline{R}_g(0)/D$ where $D$ is the $\\phi$-dependent distance between the crowders. If $x\\lesssim \\mathcal{O}(1)$, there is only a small decrease in $\\overline{R}_g(\\phi)$ as $\\phi$ increases. When $x\\gg \\mathcal{O}(1)$, a cooperative coil-to-globule transition is induced. Our theory quantitatively explains a number of experiments.

Dark Energy in the Dark Ages  

E-Print Network (OSTI)

Non-negligible dark energy density at high redshifts would indicate dark energy physics distinct from a cosmological constant or ``reasonable'' canonical scalar fields. Such dark energy can be constrained tightly through investigation of the growth of structure, with limits of \\la2% of total energy density at z\\gg1 for many models. Intermediate dark energy can have effects distinct from its energy density; the dark ages acceleration can be constrained to last less than 5% of a Hubble e-fold time, exacerbating the coincidence problem. Both the total linear growth, or equivalently \\sigma_8, and the shape and evolution of the nonlinear mass power spectrum for zenergy behavior over the entire range z=0-1100.

Can a variable gravitational constant resolve the Faint Young Sun Paradox ?  

E-Print Network (OSTI)

Solar models suggest that four billion years ago the young Sun was about 25% fainter than it is today, rendering Earth's oceans frozen and lifeless. However, there is ample geophysical evidence that Earth had a liquid ocean teeming with life 4 Gyr ago. Since ${\\cal L_\\odot} \\propto G^7M_\\odot^5$, the Sun's luminosity ${\\cal L_\\odot}$ is exceedingly sensitive to small changes in the gravitational constant $G$. We show that a percent-level increase in $G$ in the past would have prevented Earth's oceans from freezing, resolving the faint young Sun paradox. Such small changes in $G$ are consistent with observational bounds on ${\\Delta G}/G$. Since ${\\cal L}_{\\rm SNIa} \\propto G^{-3/2}$, an increase in $G$ leads to fainter supernovae, creating tension between standard candle and standard ruler probes of dark energy.

Jet conversions in a quark-gluon plasma  

Science Journals Connector (OSTI)

Quark and gluon jets traversing through a quark-gluon plasma not only lose their energies but also can undergo flavor conversions. The conversion rates via the elastic q(q)g?gq(q) and the inelastic qq?gg scatterings are evaluated in the lowest order in QCD. Including both jet energy loss and conversions in the expanding quark-gluon plasma produced in relativistic heavy ion collisions, we have found a net of quark jets to gluon jets. This reduces the difference between the nuclear modification factors for quark and gluon jets in central heavy ion collisions and thus enhances the p/?+ and p/?- ratios at high transverse momentum. However, a much larger net quark-to-gluon jet conversion rate than the one given by the lowest order QCD is needed to account for the observed similar ratios in central Au+Au and p+p collisions at the same energy. Implications of our results are discussed.

Ultra-weak sector, Higgs boson mass, and the dilaton  

SciTech Connect

The Higgs boson mass may arise from a portal coupling to a singlet field $\\sigma$ which has a very large VEV $f \\gg m_\\text{Higgs}$. This requires a sector of "ultra-weak" couplings $\\zeta_i$, where $\\zeta_i \\lesssim m_\\text{Higgs}^2 / f^2$. Ultra-weak couplings are technically naturally small due to a custodial shift symmetry of $\\sigma$ in the $\\zeta_i \\rightarrow 0$ limit. The singlet field $\\sigma$ has properties similar to a pseudo-dilaton. We engineer explicit breaking of scale invariance in the ultra-weak sector via a Coleman-Weinberg potential, which requires hierarchies amongst the ultra-weak couplings.

Thermally induced photon splitting  

E-Print Network (OSTI)

We calculate thermal corrections to the non-linear QED effective action for low-energy photon interactions in a background electromagnetic field. The high-temperature expansion shows that at $T \\gg m$ the vacuum contribution is exactly cancelled to all orders in the external field except for a non-trivial two-point function contribution. The high-temperature expansion derived reveals a remarkable cancellation of infrared sensitive contributions. As a result photon-splitting in the presence of a magnetic field is suppressed in the presence of an electron-positron QED-plasma at very high temperatures. In a cold and dense plasma a similar suppression takes place. At the same time Compton scattering dominates for weak fields and the suppression is rarely important in physical situations.

Measurement of the production and muonic decay rate of W and Z bosons in pp collisions at ?s =1.8 TeV  

Science Journals Connector (OSTI)

An analysis of proton-antiproton collisions at ?s =1.8 TeV recorded with the Collider Detector at Fermilab (CDF) yields ?(pp?WX)B(W???)=2.210.22 nb and ?(pp?ZX)B(Z ??+?-)=0.2260.032 nb. The ratio is R?=?WB(W???)/?ZB(Z??+?-)=9.81.2. Combining with previous CDF electron results gives ?WB(W?l?)=2.200.20 nb, ?ZB(Z?l+l-)=0.2140.023 nb, and Rl=10.00.8. We extract the ratios of the coupling constants g?/ge and g?/g?. Using standard model assumptions we deduce the inverse branching ratio B-1(W?l?), the width ?(W), and a decay-mode-independent lower bound on the top quark mass of 45 GeV/c2 (95% C.L.).

Flash of prompt photons from the early stage of heavy-ion collisions  

SciTech Connect

We briefly recall the tremendous strides in the studies of the parton cascade model made by Klaus Geiger. Next, we argue that photons may provide confirmation of several of these ideas. Thus we know that, copious internetted partonic cascades may develop in the wake of relativistic collisions of nuclei at CERN SPS and BNL RHIC energies, We use the parton cascade model to estimate the emission of single photons generated from such cascades due to the branching of quarks q{yields}q{gamma}, scattering of quarks and gluons, and annihilation of quarks. The formation of a hot and dense partonic matter is shown to be preceded by an intense radiation of photons from the QED branching of quarks. This is similar to the QCD branching q{yields}qg which along with the gluon multiplication (g{yields}gg) which is known to play a crucial role in the formation of the dense partonic plasma.

Fluidised bed co-gasification of coal and olive oil industry wastes  

Science Journals Connector (OSTI)

Co-gasification of bagasse wastes mixed with coal is technically feasible, without major installation changes. The effect of experimental conditions on co-gasification process was analysed, to enhance gas production and improve its composition and energetic content. The rise of bagasse content increased tars and gaseous hydrocarbons contents, which can be reduced by increasing gasification temperature and/or air flow rate. The rise of temperature till 890C favoured hydrocarbons further reactions and allowed an increase of 45% in hydrogen release and a decrease in gaseous hydrocarbons of 55%. A reduction of around 30% in gaseous hydrocarbons was also achieved by rising O2/fuel ratio till 0.6g/g daf, which decreased gas heating value, due to nitrogen diluting effect. Though no significant changes in gaseous hydrocarbons composition were obtained, the presence of dolomite in the fluidised bed had the benefit of decreasing tars content and rising gas yield, being the gas richer in hydrogen content.

Synthesis and characterization of superabsorbent polymer prepared by radiation-induced graft copolymerization of acrylamide onto carboxymethyl cellulose for controlled release of agrochemicals  

Science Journals Connector (OSTI)

Abstract Superabsorbent polymer (SAP) was synthesized by radiation-induced grafting of acrylamide (AM) onto carboxymethyl cellulose (CMC) in the presence of a crosslinking agent, N,N?-methylenebisacrylamide (MBA). The effects of various parameters, such as dose, the amount of CMC, AM, MBA and ionic strength on the swelling ratio were investigated. In order to evaluate its controlled release potential, SAP was loaded with potassium nitrate (KNO3) as an agrochemical model and its potential for controlled release of KNO3 was studied. The amount of released KNO3 was analyzed by an inductively coupled plasma mass spectrometry (ICPMS). The results from controlled release experiment agreed very well with the results from swelling experiment. The synthesized SAP was characterized by Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). The obtained SAP exhibited a swelling ratio of 190g/g of dry gel.

Gluino polarization at the LHC  

Science Journals Connector (OSTI)

Gluinos are produced pairwise at the LHC in quark-antiquark and gluon-gluon collisions: qq, gg?gg. While the individual polarization of gluinos vanishes in the limit in which the small mass difference between L and R squarks of the first two generations is neglected, nonzero spin-spin correlations are predicted within gluino pairs. If the squark/quark charges in Majorana gluino decays are tagged, the spin correlations have an impact on the energy and angular distributions in reconstructed final states. On the other hand, the gluino polarization in single gluino production in the supersymmetric Compton process gq?gqR,L is predicted to be nonzero, and the polarization affects the final-state distributions in super-Compton events.

DNA unwinding produced by site-specific intrastrand cross-links of the antitumor drug cis-diamminedichloroplatinum(II)  

SciTech Connect

The DNA unwinding produced by specific adducts of the antitumor drug cis-diamminedi-chloroplatinum(II) has been quantitatively determined. Synthetic DNA duplex oligonucleotides of varying lengths with two base pair cohesive ends were synthesized and characterized that contained site-specific intrastrand N7-purine/N7-purine cross-links. Included are cis-(Pt(NH{sub 3}){sub 2}(d(GpG))), cis-(Pt(NH){sub 3}{sub 2}(d(ApG))), and cis-(Pt(NH{sub 3}){sub 2}(d(GpTpG))) adducts, respectively referred to as cis-GG, cis-AG, and cis-GTG. Local DNA distortions at the site of platination were amplified by polymerization of these monomers and quantitatively evaluated by using polyacrylamide gel electrophoresis. The extent of DNA unwinding was determined by systematically varying the interplatinum distance, or phasing, in polymers containing the adducts. The multimer that migrates most slowly gives the optimal phasing for cooperative bending, from which the degree of unwinding can be obtained. The authors find that the cis-GG and cis-AG adducts both unwind DNA by 13{degrees}, while the cis-GTG adduct unwinds DNA by 23{degrees}. In addition, experiments are presented that support previous studies revealing that a hinge joint forms at the sites of platination in DNA molecules containing trans-GTG adducts. On the basis of an analysis of the present and other published studies of site-specifically modified DNA. The authors propose that local duplex unwinding is a major determinant in the recognition of DNA damage by the Escherichia coli (A)BC excinuclease. In addition, local duplex unwinding of 13{degrees} and bending by 35{degrees} are shown to correlate well with the recognition of platinated DNA by a previously identified damage recognition protein (DRP) in human cells.

Effective growth of matter density fluctuations in the running LCDM and LXCDM models  

E-Print Network (OSTI)

We investigate the matter density fluctuations \\delta\\rho/\\rho for two dark energy (DE) models in the literature in which the cosmological term \\Lambda is a running parameter. In the first model, the running LCDM model, matter and DE exchange energy, whereas in the second model, the LXCDM model, the total DE and matter components are conserved separately. The LXCDM model was proposed as an interesting solution to the cosmic coincidence problem. It includes an extra dynamical component, the "cosmon" X, which interacts with the running \\Lambda, but not with matter. In our analysis we make use of the current value of the linear bias parameter, b^2(0)= P_{GG}/P_{MM}, where P_{MM} ~ (\\delta\\rho/\\rho)^2 is the present matter power spectrum and P_{GG} is the galaxy fluctuation power spectrum. The former can be computed within a given model, and the latter is found from the observed LSS data (at small z) obtained by the 2dF galaxy redshift survey. It is found that b^2(0)=1 within a 10% accuracy for the standard LCDM model. Adopting this limit for any DE model and using a method based on the effective equation of state for the DE, we can set a limit on the growth of matter density perturbations for the running LCDM model, the solution of which is known. This provides a good test of the procedure, which we then apply to the LXCDM model in order to determine the physical region of parameter space, compatible with the LSS data. In this region, the LXCDM model is consistent with known observations and provides at the same time a viable solution to the cosmic coincidence problem.

Single top-quark production by strong and electroweak supersymmetric flavor-changing interactions at the LHC  

E-Print Network (OSTI)

(Abridged) We report on a complete study of the single top-quark production by direct supersymmetric flavor-changing neutral-current (FCNC) processes at the LHC. The total cross section for pp(gg)->t\\bar{c}+\\bar{t}c is computed at the 1-loop order within the unconstrained Minimal Supersymmetric Standard Model (MSSM). The present study extends the results of the supersymmetric strong effects (SUSY-QCD), which were advanced by some of us in a previous work, and includes the computation of the full supersymmetric electroweak corrections (SUSY-EW). Our analysis of pp(gg)->t\\bar{c}+\\bar{t}c in the MSSM has been performed in correspondence with the stringent low-energy constraints from b->s gamma. In the most favorable scenarios, the SUSY-QCD contribution can give rise to production rates of around 10^5 events per 100 fb^{-1} of integrated luminosity. Furthermore, we show that there exist regions of the MSSM parameter space where the SUSY-EW correction becomes sizeable. In the SUSY-EW favored regions, one obtains lower, but still appreciable, event production rates that can reach the 10^3 level for the same range of integrated luminosity. We study also the possible reduction in the maximum event rate obtained from the full MSSM contribution if we additionally include the constraints from B^0_s-\\bar{B}^0_s. In view of the fact that the FCNC production of heavy quark pairs of different flavors is extremely suppressed in the SM, the detection of a significant number of these events could lead to evidence of new physics -- of likely supersymmetric origin.

KEPLER-63b: A GIANT PLANET IN A POLAR ORBIT AROUND A YOUNG SUN-LIKE STAR  

SciTech Connect

We present the discovery and characterization of a giant planet orbiting the young Sun-like star Kepler-63 (KOI-63, m{sub Kp} = 11.6, T{sub eff} = 5576 K, M{sub *} = 0.98 M{sub ?}). The planet transits every 9.43 days, with apparent depth variations and brightening anomalies caused by large starspots. The planet's radius is 6.1 0.2 R{sub ?}, based on the transit light curve and the estimated stellar parameters. The planet's mass could not be measured with the existing radial-velocity data, due to the high level of stellar activity, but if we assume a circular orbit, then we can place a rough upper bound of 120 M{sub ?} (3?). The host star has a high obliquity (? = 104), based on the Rossiter-McLaughlin effect and an analysis of starspot-crossing events. This result is valuable because almost all previous obliquity measurements are for stars with more massive planets and shorter-period orbits. In addition, the polar orbit of the planet combined with an analysis of spot-crossing events reveals a large and persistent polar starspot. Such spots have previously been inferred using Doppler tomography, and predicted in simulations of magnetic activity of young Sun-like stars.

Measurement of the strong interaction induced shift and width of the 1s state of kaonic deuterium at J-PARC  

E-Print Network (OSTI)

The antikaon-nucleon interaction close to threshold provides crucial information on the interplay between spontaneous and explicit chiral symmetry breaking in low-energy QCD. In this context the importance of kaonic deuterium X-ray spectroscopy has been well recognized, but no experimental results have yet been obtained due to the difficulty of the measurement. We propose to measure the shift and width of the kaonic deuterium 1s state with an accuracy of 60 eV and 140 eV respectively at J-PARC. These results together with the kaonic hydrogen data (KpX at KEK, DEAR and SIDDHARTA at DAFNE) will then permit the determination of values of both the isospin I=0 and I=1 antikaon-nucleon scattering lengths and will provide the most stringent constraints on the antikaon-nucleon interaction, promising a breakthrough. Refined Monte Carlo studies were performed, including the investigation of background suppression factors for the described setup. These studies have demonstrated the feasibility of determining the shift a...

Simulation of coal combustion by AUSM turbulence-chemistry char combustion model and a full two-fluid model  

Science Journals Connector (OSTI)

An algebraic unified second-order moment (AUSM) turbulence-chemistry model of char combustion is introduced in this paper, to calculate the effect of particle temperature fluctuation on char combustion. The AUSM model is used to simulate gas-particle flows, in coal combustion in a pulverized coal combustor, together with a full two-fluid model for reacting gas-particle flows and coal combustion, including the sub-models as the k-?-kp two-phase turbulence model, the EBU-Arrhenius volatile and CO combustion model, and the six-flux radiation model. A new method for calculating particle mass flow rate is also used in this model to correct particle outflow rate and mass flow rate for inside sections, which can obey the principle of mass conservation for the particle phase and can also speed up the iterating convergence of the computation procedure effectively. The simulation results indicate that, the AUSM char combustion model is more preferable to the old char combustion model, since the later totally eliminate the influence of particle temperature fluctuation on char combustion rate.

Computational fluid dynamics simulation of hydrodynamics and chemical reaction in a CFB downer  

Science Journals Connector (OSTI)

Abstract A computational fluid dynamics (CFD) model for simulating the chemical reaction process in a gasparticle circulating fluidized bed (CFB) downer is introduced by combining the two-fluid model (TFM) for the gasparticle turbulent flows and the c 2 ? ? c model for the turbulent mass transfer. With the proposed model, the species concentration and solid volume fraction as well as the velocity distributions along the CFB downer are able to be predicted. In mathematical expression of the proposed model, the recently developed formulations of c 2 ? ? c is adopted to close the turbulent mass transfer equations so that the turbulent mass diffusivity can be determined without relying on empirical methods. As for the gassolid two phase turbulent momentum transfer equations, the methodology of kg??g?kp??p?? is used for their closures. To validate the proposed model, simulation is carried out for the catalytic ozone decomposition in a gassolid CFB downer. The simulation results are compared with the experimental data and satisfactory agreement is found between them in both axial/radial distributions of concentration and solid volume fraction. Furthermore, the simulations reveal that the turbulent mass diffusivity varies along axial and radial directions, and the turbulent Schmidt number is not a constant throughout the CFB downer.
