Increasing available FIFO space to prevent messaging queue deadlocks in a DMA environment  

DOE Patents (OSTI)

Embodiments of the invention may be used to manage message queues in a parallel computing environment to prevent message queue deadlock. A direct memory access controller of a compute node may determine when a messaging queue is full. In response, the DMA may generate an interrupt. An interrupt handler may stop the DMA and swap all descriptors from the full messaging queue into a larger queue (or enlarge the original queue). The interrupt handler then restarts the DMA. Alternatively, the interrupt handler stops the DMA, allocates a memory block to hold queue data, and then moves descriptors from the full messaging queue into the allocated memory block. The interrupt handler then restarts the DMA. During a normal messaging advance cycle, a messaging manager attempts to inject the descriptors in the memory block into other messaging queues until the descriptors have all been processed.

QMP: LQCD Message Passing API  

Science Conference Proceedings (OSTI)

Recent changes are: (1) There is no longer a logical node number, only a node number which does not change as the logical machine is define. Thus there are two styles of messaging: messages are sent to a node by node number, or messages are sent to a relative (logical) node. (2) Methods related to node numbers have been changed (some dropped, some added). This note presents: (1) the requirements for message passing within Lattice QCD applications; (2) a draft message API for both C and C++; and (3) implementation design ideas. The API is intended to be sufficiently flexible to be used by all Lattice QCD applications, and execute efficiently on all existing and anticipated platforms, so that there is no need to directly call non-portable message passing routines. Because of the highly regular grid communications with LQCD, MPI calls (which are more general) impose some additional overhead that is predicted to be non-negligible for large machines. Depending upon demand, a subset of MPI could be implemented above this new API so that legacy codes which use MPI could function on the new architectures which implement (only) the new API. Further, the new API has been implemented atop MPI so that new applications using this new API can still be run on older machines for which only MPI is available. Interspersed with the API description are some descriptions for how the API could be implemented for myrinet clusters and the QCDOC machine. These are meant to more fully illustrate the functionality, and are not intended as the final design. At the time of writing, the following implementations exist: (1) QMP-GM -- Uses GM; (2) QMP-MPI -- Uses MPI; tested above MPICH-GM, MPICH-SM (shared memory), and MPICH-P4 (sockets).

Message passing with queues and channels  

Science Conference Proceedings (OSTI)

In an embodiment, a send thread receives an identifier that identifies a destination node and a pointer to data. The send thread creates a first send request in response to the receipt of the identifier and the data pointer. The send thread selects a selected channel from among a plurality of channels. The selected channel comprises a selected hand-off queue and an identification of a selected message unit. Each of the channels identifies a different message unit. The selected hand-off queue is randomly accessible. If the selected hand-off queue contains an available entry, the send thread adds the first send request to the selected hand-off queue. If the selected hand-off queue does not contain an available entry, the send thread removes a second send request from the selected hand-off queue and sends the second send request to the selected message unit.

Direct quantum communication without actual transmission of the message qubits  

E-Print Network (OSTI)

Recently an orthogonal state based protocol of direct quantum communication without actual transmission of particles is proposed by Salih \\emph{et al.}{[}Phys. Rev. Lett. \\textbf{110} (2013) 170502{]} using chained quantum Zeno effect. As the no-transmission of particle claim is criticized by Vaidman {[}arXiv:1304.6689 (2013){]}, the condition (claim) of Salih \\emph{et al.} is weaken here to the extent that transmission of particles is allowed, but transmission of the message qubits (the qubits on which the secret information is encoded) is not allowed. Remaining within this weaker condition it is shown that there exists a large class of quantum states, that can be used to implement an orthogonal state based protocol of secure direct quantum communication using entanglement swapping, where actual transmission of the message qubits is not required. The security of the protocol originates from monogamy of entanglement. As the protocol can be implemented without using conjugate coding its security is independent of non-commutativity.

Tracking particles by passing messages between images  

SciTech Connect

Methods to extract information from the tracking of mobile objects/particles have broad interest in biological and physical sciences. Techniques based on the simple criterion of proximity in time-consecutive snapshots are useful to identify the trajectories of the particles. However, they become problematic as the motility and/or the density of the particles increases because of the uncertainties on the trajectories that particles have followed during the acquisition time of the images. Here, we report efficient methods for learning parameters of the dynamics of the particles from their positions in time-consecutive images. Our algorithm belongs to the class of message-passing algorithms, also known in computer science, information theory and statistical physics under the name of Belief Propagation (BP). The algorithm is distributed, thus allowing parallel implementation suitable for computations on multiple machines without significant inter-machine overhead. We test our method on the model example of particle tracking in turbulent flows, which is particularly challenging due to the strong transport that those flows produce. Our numerical experiments show that the BP algorithm compares in quality with exact Markov Chain Monte-Carlo algorithms, yet BP is far superior in speed. We also suggest and analyze a random-distance model that provides theoretical justification for BP accuracy. Methods developed here systematically formulate the problem of particle tracking and provide fast and reliable tools for its extensive range of applications.

Characteristics of the Unexpected Message Queue of MPI applications  

Science Conference Proceedings (OSTI)

High Performance Computing systems are used on a regular basis to run a myriad of application codes, yet a surprising dearth of information exists with respect to communications characteristics. Even less information is available on the low-level communication libraries, such as the length of MPI Unexpected Message Queues (UMQs) and the length of time such messages spend in these queues. Such information is vital to developing appropriate strategies for handling such data at the library and system level. In this paper we present data on the communication characteristics of three applications GTC, LSMS, and S3D. We present data on the size of their UMQ, the time spend searching the UMQ and the length of time such messages spend in these queues. We find that for the particular inputs used, these applications have widely varying characteristics with regard to UMQ length and show patterns for specific applications which persist over various scales.

Extensible message passing application development and debugging with Python  

SciTech Connect

The authors describe how they have parallelized Python, an interpreted object oriented scripting language, and used it to build an extensible message-passing C/C++ applications for the CM-5, Cray T3D, and Sun multiprocessor servers running MPI. Using a parallelized Python interpreter, it is possible to interact with large-scale parallel applications, rapidly prototype new features, and perform application specific debugging. It is even possible to write message passing programs in Python itself. The authors describe some of the tools they have developed to extend Python and applications of this approach.

GMH: A Message Passing Toolkit for GPU Clusters  

Science Conference Proceedings (OSTI)

Driven by the market demand for high-definition 3D graphics, commodity graphics processing units (GPUs) have evolved into highly parallel, multi-threaded, many-core processors, which are ideal for data parallel computing. Many applications have been ported to run on a single GPU with tremendous speedups using general C-style programming languages such as CUDA. However, large applications require multiple GPUs and demand explicit message passing. This paper presents a message passing toolkit, called GMH (GPU Message Handler), on NVIDIA GPUs. This toolkit utilizes a data-parallel thread group as a way to map multiple GPUs on a single host to an MPI rank, and introduces a notion of virtual GPUs as a way to bind a thread to a GPU automatically. This toolkit provides high performance MPI style point-to-point and collective communication, but more importantly, facilitates event-driven APIs to allow an application to be managed and executed by the toolkit at runtime.

How to communicate unit error messages in spreadsheets  

E-Print Network (OSTI)

In previous work we have designed and implemented an automatic reasoning system for spreadsheets, called UCheck, that infers unit information for cells in a spreadsheet. Based on this unit information, UCheck can identify cells in the spreadsheet that contain erroneous formulas. However, the information about an erroneous cell is reported to the user currently in a rather crude way by simply coloring the cell, which does not tell anything about the nature of error and thus offers no help to the user as to how to fix it. In this paper we describe an extension of UCheck, called UFix, which improves the error messages reported to the spreadsheet user dramatically. The approach essentially consists of three steps: First, we identify different categories of spreadsheet errors from an end-user’s perspective. Second, we map units that indicate erroneous formulas to these error categories. Finally, we create customized error messages from the unit information and the identified error category. In many cases, these error messages also provide suggestions on how to fix the reported errors.

Multiple Access Channels with Generalized Feedback and Confidential Messages  

E-Print Network (OSTI)

This paper considers the problem of secret communication over a multiple access channel with generalized feedback. Two trusted users send independent confidential messages to an intended receiver, in the presence of a passive eavesdropper. In this setting, an active cooperation between two trusted users is enabled through using channel feedback in order to improve the communication efficiency. Based on rate-splitting and decode-and-forward strategies, achievable secrecy rate regions are derived for both discrete memoryless and Gaussian channels. Results show that channel feedback improves the achievable secrecy rates.

Ecological Evaluation of Persuasive Messages Using Google AdWords  

E-Print Network (OSTI)

In recent years there has been a growing interest in crowdsourcing methodologies to be used in experimental research for NLP tasks. In particular, evaluation of systems and theories about persuasion is difficult to accommodate within existing frameworks. In this paper we present a new cheap and fast methodology that allows fast experiment building and evaluation with fully-automated analysis at a low cost. The central idea is exploiting existing commercial tools for advertising on the web, such as Google AdWords, to measure message impact in an ecological setting. The paper includes a description of the approach, tips for how to use AdWords for scientific research, and results of pilot experiments on the impact of affective text variations which confirm the effectiveness of the approach.

High-Performance Buildings – Value, Messaging, Financial and Policy Mechanisms  

SciTech Connect

At the request of the Pacific Northwest National Laboratory, an in-depth analysis of the rapidly evolving state of real estate investments, high-performance building technology, and interest in efficiency was conducted by HaydenTanner, LLC, for the U.S. Department of Energy (DOE) Building Technologies Program. The analysis objectives were • to evaluate the link between high-performance buildings and their market value • to identify core messaging to motivate owners, investors, financiers, and others in the real estate sector to appropriately value and deploy high-performance strategies and technologies across new and existing buildings • to summarize financial mechanisms that facilitate increased investment in these buildings. To meet these objectives, work consisted of a literature review of relevant writings, examination of existing and emergent financial and policy mechanisms, interviews with industry stakeholders, and an evaluation of the value implications through financial modeling. This report documents the analysis methodology and findings, conclusion and recommendations. Its intent is to support and inform the DOE Building Technologies Program on policy and program planning for the financing of high-performance new buildings and building retrofit projects.

Eliminating livelock by assigning the same priority state to each message that is inputted into a flushable routing system during N time intervals  

DOE Patents (OSTI)

Livelock-free message routing is provided in a network of interconnected nodes that is flushable in time T. An input message processor generates sequences of at least N time intervals, each of duration T. An input register provides for receiving and holding each input message, where the message is assigned a priority state p during an nth one of the N time intervals. At each of the network nodes a message processor reads the assigned priority state and awards priority to messages with priority state (p-1) during an nth time interval and to messages with priority state p during an (n+1) th time interval. The messages that are awarded priority are output on an output path toward the addressed output message processor. Thus, no message remains in the network for a time longer than T.

DECODING THE MESSAGE FROM METEORITIC STARDUST SILICON CARBIDE GRAINS  

SciTech Connect

Micron-sized stardust grains that originated in ancient stars are recovered from meteorites and analyzed using high-resolution mass spectrometry. The most widely studied type of stardust is silicon carbide (SiC). Thousands of these grains have been analyzed with high precision for their Si isotopic composition. Here we show that the distribution of the Si isotopic composition of the vast majority of stardust SiC grains carries the imprints of a spread in the age-metallicity distribution of their parent stars and of a power-law increase of the relative formation efficiency of SiC dust with the metallicity. This result offers a solution for the long-standing problem of silicon in stardust SiC grains, confirms the necessity of coupling chemistry and dynamics in simulations of the chemical evolution of our Galaxy, and constrains the modeling of dust condensation in stellar winds as a function of the metallicity.

1 Rhythms of social interaction: messaging within a massive online network  

E-Print Network (OSTI)

Summary. We have analyzed the fully-anonymized headers of 362 million messages exchanged by 4.2 million users of Facebook, an online social network of college students, during a 26 month interval. The data reveal a number of strong daily and weekly regularities which provide insights into the time use of college students and their social lives, including seasonal variations. We also examined how factors such as school affiliation and informal online “friend” lists affect the observed behavior and temporal patterns. Finally, we show that Facebook users appear to be clustered by school with respect to their temporal messaging patterns. 1.1

Decoding the `Nature Encoded' Messages for Distributed Energy Generation Control in Microgrid  

E-Print Network (OSTI)

The communication for the control of distributed energy generation (DEG) in microgrid is discussed. Due to the requirement of realtime transmission, weak or no explicit channel coding is used for the message of system state. To protect the reliability of the uncoded or weakly encoded messages, the system dynamics are considered as a `nature encoding' similar to convolution code, due to its redundancy in time. For systems with or without explicit channel coding, two decoding procedures based on Kalman filtering and Pearl's Belief Propagation, in a similar manner to Turbo processing in traditional data communication systems, are proposed. Numerical simulations have demonstrated the validity of the schemes, using a linear model of electric generator dynamic system.

Message and State Cooperation in a Relay Channel When Only the Relay Knows the State  

E-Print Network (OSTI)

A state-dependent relay channel is studied in which strictly causal channel state information is available at the relay and no state information is available at the source and destination. The source and the relay are connected via two unidirectional out-of-band orthogonal links of finite capacity, and a state-dependent memoryless channel connects the source and the relay, on one side, and the destination, on the other. Via the orthogonal links, the source can convey information about the message to be delivered to the destination to the relay while the relay can forward state information to the source. This exchange enables cooperation between the source and the relay on transmission of message and state information to the destination. First, two achievable schemes are proposed that exploit both message and state cooperation. It is shown that a transmission scheme inspired by noisy network coding performs better than a strategy based on block Markov coding and backward decoding. Next, based on the given achi...

Thermodynamic Origin of Life  

E-Print Network (OSTI)

Understanding the thermodynamic function of life may shed light on its origin. Life, as are all irreversible processes, is contingent on entropy production. Entropy production is a measure of the rate of the tendency of Nature to explore available microstates. The most important irreversible process generating entropy in the biosphere, and thus facilitating this exploration, is the absorption and transformation of sunlight into heat. Here we hypothesize that life began, and persists today, as a catalyst for the absorption and dissipation of sunlight at the surface of shallow seas. The resulting heat is then efficiently harvested by other irreversible processes such as the water cycle, hurricanes, and ocean and wind currents. RNA and DNA are the most efficient of all known molecules for absorbing the intense ultraviolet light that could have penetrated the dense early atmosphere, and are remarkably rapid in transforming this light into heat in the presence of liquid water. From this perspective, the origin and evolution of life, inseparable from water and the water cycle, can be understood as resulting from the natural thermodynamic imperative of increasing the entropy production of the Earth in its interaction with its solar environment. A mechanism is proposed for the reproduction of RNA and DNA without the need for enzymes, promoted instead through UV light dissipation and the ambient conditions of prebiotic Earth.

A scalable messaging system for accelerating discovery from large scale scientific simulations  

SciTech Connect

Emerging scientific and engineering simulations running at scale on leadership-class High End Computing (HEC) environments are producing large volumes of data, which has to be transported and analyzed before any insights can result from these simulations. The complexity and cost (in terms of time and energy) associated with managing and analyzing this data have become significant challenges, and are limiting the impact of these simulations. Recently, data-staging approaches along with in-situ and in-transit analytics have been proposed to address these challenges by offloading I/O and/or moving data processing closer to the data. However, scientists continue to be overwhelmed by the large data volumes and data rates. In this paper we address this latter challenge. Specifically, we propose a highly scalable and low-overhead associative messaging framework that runs on the data staging resources within the HEC platform, and builds on the staging-based online in-situ/in- transit analytics to provide publish/subscribe/notification-type messaging patterns to the scientist. Rather than having to ingest and inspect the data volumes, this messaging system allows scientists to (1) dynamically subscribe to data events of interest, e.g., simple data values or a complex function or simple reduction (max()/min()/avg()) of the data values in a certain region of the application domain is greater/less than a threshold value, or certain spatial/temporal data features or data patterns are detected; (2) define customized in-situ/in-transit actions that are triggered based on the events, such as data visualization or transformation; and (3) get notified when these events occur. The key contribution of this paper is a design and implementation that can support such a messaging abstraction at scale on high- end computing (HEC) systems with minimal overheads. We have implemented and deployed the messaging system on the Jaguar Cray XK6 machines at Oak Ridge National Laboratory and the Lonestar system at the Texas Advanced Computing Center (TACC), and we present the experimental performance evaluation using these HEC platforms in the paper.

Origin of solar magnetism  

E-Print Network (OSTI)

The most promising model for explaining the origin of solar magnetism is the flux transport dynamo model, in which the toroidal field is produced by differential rotation in the tachocline, the poloidal field is produced by the Babcock--Leighton mechanism at the solar surface and the meridional circulation plays a crucial role. After discussing how this model explains the regular periodic features of the solar cycle, we come to the questions of what causes irregularities of solar cycles and whether we can predict future cycles. Only if the diffusivity within the convection zone is sufficiently high, the polar field at the sunspot minimum is correlated with strength of the next cycle. This is in conformity with the limited available observational data.

Original Budget Expended  

E-Print Network (OSTI)

The goal of the project was to reduce phosphorus (P) loading in South Dakota by characterizing the P loading contributions of South Dakota soils and improving manure management strategies by better understanding the relationships that exist among soil test phosphorus (STP), saturation P, and runoff P for select benchmark soils. Information gained during the project was used to develop improved manure management BMPs based on soil and runoff P relationships. Stakeholder education and communication of effective manure management to livestock producers was a component of the project. The project determined correlations between STP and runoff P for five soils located across eastern South Dakota. This was two more than the three soil series planned in the original project. Other accomplishments included evaluating the correlations among P saturation and soil test P, and surface runoff P for the five benchmark soils. The data was used to develop manure management BMPs and guidelines to improve manure application strategies and protect water quality. This project was a major step to understanding sources of nonpoint source nutrient loading of South Dakota’s water resources. Information collected on South Dakota soils was essential for producer acceptance of phosphorus-based manure management.

MPICH-GQ: quality-of-service for message passing programs  

SciTech Connect

Parallel programmers typically assume that all resources required for a program's execution are dedicated to that purpose. However, in local and wide area networks, contention for shared networks, CPUs, and I/O systems can result in significant variations in availability, with consequent adverse effects on overall performance. The authors describe a new message-passing architecture, MPICH-GQ, that uses quality of service (QoS) mechanisms to manage contention and hence improve performance of message passing interface (MPI) applications. MPICH-GQ combines new QoS specification, traffic shaping, QoS reservation, and QoS implementation techniques to deliver QoS capabilities to the high-bandwidth bursty flows, complex structures, and reliable protocols used in high-performance applications--characteristics very different from the low-bandwidth, constant bit-rate media flows and unreliable protocols for which QoS mechanisms were designed. Results obtained on a differentiated services testbed demonstrate their ability to maintain application performance in the face of heavy network contention.

Building Efficient Limited Directory-Based DSMs: A Multidestination Message Passing Based  

E-Print Network (OSTI)

: A cost-effective distributed shared memory (DSM) system typically uses a limited directory protocol to enforce cache coherence. This paper presents a new family of protocols, called Limited directory with Region-based Broadcast (Limited-RB), to efficiently implement cache coherence in wormhole routed DSM systems. This protocol family uses multidestinationbased cache invalidation mechanisms to distribute invalidation requests to and collect the associated acknowledgments from separate regions. As a result, a write invalidation can be accomplished with fewer messages, less network traffic, and reduced occupancy at home nodes. These reductions contribute to decreasing invalidation latency and improving overall system performance. Directory organization under this new protocol is developed for 2D systems with e-cube routing and evaluated through simulations for a set of applications. The results indicate that with a small directory storage, the Limited-RB protocol family can achieve supe...

Message passing for integrating and assessing renewable generation in a redundant power grid  

SciTech Connect

A simplified model of a redundant power grid is used to study integration of fluctuating renewable generation. The grid consists of large number of generator and consumer nodes. The net power consumption is determined by the difference between the gross consumption and the level of renewable generation. The gross consumption is drawn from a narrow distribution representing the predictability of aggregated loads, and we consider two different distributions representing wind and solar resources. Each generator is connected to D consumers, and redundancy is built in by connecting R {le} D of these consumers to other generators. The lines are switchable so that at any instance each consumer is connected to a single generator. We explore the capacity of the renewable generation by determining the level of 'firm' generation capacity that can be displaced for different levels of redundancy R. We also develop message-passing control algorithm for finding switch sellings where no generator is overloaded.

A grid-enabled MPI : message passing in heterogeneous distributed computing systems.  

SciTech Connect

Application development for high-performance distributed computing systems, or computational grids as they are sometimes called, requires grid-enabled tools that hide mundate aspects of the heterogeneous grid environment without compromising performance. As part of an investigation of these issues, they have developed MPICH-G, a grid-enabled implementation of the Message Passing Interface (MPI) that allows a user to run MPI programs across multiple computers at different sites using the same commands that would be used on a parallel computer. This library extends the Argonne MPICH implementation of MPI to use services provided by the globus grid toolkit. In this paper, they describe the MPICH-G implementation and present preliminary performance results.

A uGNI-Based Asynchronous Message-driven Runtime System for Cray Supercomputers with Gemini Interconnect  

SciTech Connect

Gemini as the network for new Cray XE/XT systems features low latency, high bandwidth and strong scalability. Its hardware support for remote direct memory access enables efficient implementation of the global address space programming languages. Although the Generic Network Interface (GNI) is designed to support message-passing applications, it is still challenging to attain good performance for applications written in alternative programming models, such as the message-driven programming model. In our earlier work we showed that CHARM++, an object-oriented message-driven programming model, scales up to the full Jaguar Cray machine. In this paper, we describe a general and light-weight asynchronous Low-level RunTime System (LRTS) for CHARM+, and its implementation on the uGNI software stack for Cray XE systems. Several techniques are presented to exploit the uGNI capability by reducing memory copy and registration overhead, taking advantage of persistent communication, and improving intra-node communication. Our micro-benchmark results demonstrate that the uGNI-based runtime system outperforms the MPI-based implementation by up to 50% in terms of message latency. For communication intensive applications such as N-Queens, this implementation scales up to 15,360 cores of a Cray XE6 machine and is 70% faster than an MPI-based implementation. In molecular dynamics application NAMD, the performance is also considerably improved by as high as 18%.

Awareness, Preference, Utilization, and Messaging Research for the Spallation Neutron Source and High Flux Isotope Reactor  

Science Conference Proceedings (OSTI)

Oak Ridge National Laboratory (ORNL) offers the scientific community unique access to two types of world-class neutron sources at a single site - the Spallation Neutron Source (SNS) and the High Flux Isotope Reactor (HFIR). The 85-MW HFIR provides one of the highest steady-state neutron fluxes of any research reactor in the world, and the SNS is one of the world's most intense pulsed neutron beams. Management of these two resources is the responsibility of the Neutron Sciences Directorate (NScD). NScD commissioned this survey research to develop baseline information regarding awareness of and perceptions about neutron science. Specific areas of investigative interest include the following: (1) awareness levels among those in the scientific community about the two neutron sources that ORNL offers; (2) the level of understanding members of various scientific communities have regarding benefits that neutron scattering techniques offer; and (3) any perceptions that negatively impact utilization of the facilities. NScD leadership identified users of two light sources in North America - the Advanced Photon Source (APS) at Argonne National Laboratory and the National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory - as key publics. Given the type of research in which these scientists engage, they would quite likely benefit from including the neutron techniques available at SNS and HFIR among their scientific investigation tools. The objective of the survey of users of APS, NSLS, SNS, and HFIR was to explore awareness of and perceptions regarding SNS and HFIR among those in selected scientific communities. Perceptions of SNS and FHIR will provide a foundation for strategic communication plan development and for developing key educational messages. The survey was conducted in two phases. The first phase included qualitative methods of (1) key stakeholder meetings; (2) online interviews with user administrators of APS and NSLS; and (3) one-on-one interviews and traditional and online focus groups with scientists. The latter include SNS, HFIR, and APS users as well as scientists at ORNL, some of whom had not yet used HFIR and/or SNS. These approaches informed development of the second phase, a quantitative online survey. The survey consisted of 16 questions and 7 demographic categorizations, 9 open-ended queries, and 153 pre-coded variables and took an average time of 18 minutes to complete. The survey was sent to 589 SNS/HFIR users, 1,819 NSLS users, and 2,587 APS users. A total of 899 individuals provided responses for this study: 240 from NSLS; 136 from SNS/HFIR; and 523 from APS. The overall response rate was 18%.

A supersymmetric origin of gamma ray bursts  

E-Print Network (OSTI)

Bright bursts of gamma rays from outer space have been puzzling Astronomers for more than thirty years and there is still no conceptually complete model for the phenomenon within the standard model of particle physics. Is it time to consider a supersymmetric (SUSY) origin for these bursts to add to the astronomical indications of supersymmetry from dark matter?

It is well-known that when searching one out of four, the original Grover's search algorithm is exact; that is, it succeeds with certainty. It is natural to ask the inverse question: If we are not searching one out of four, is Grover's algorithm definitely not exact? In this article we give a complete answer to this question through some rationality results of trigonometric functions.

Origin of axial current in scyllac  

SciTech Connect

The origin of the axial current observed in Scyllac (a high beta stellarator experiment) is discussed. A shaped coil and/or helical winding produce rotational transform which links magnetic lines of force to the plasma column and the axial current is induced electromagnetically. This phenomenon is inherent in a pulsed high-beta stellarator. The rotational transform produced by the induced axial current is much smaller than that associated with the l = 1, 0 equilibrium fields. The effect of the axial current on the equilibrium and stability of the plasma column is thus small. It is also shown that the magnetic field shear near a plasma surface is very strong. (auth)

Origin of holographic dark energy models  

E-Print Network (OSTI)

We investigate the origin of holographic dark energy models which were recently proposed to explain the dark energy-dominated universe. For this purpose, we introduce the spacetime foam uncertainty of $\\delta l \\ge l_{\\rm p}^{\\alpha}l^{\\alpha-1}$. It was argued that the case of $\\alpha=2/3$ could describe the dark energy with infinite statistics, while the case of $\\alpha=1/2$ can describe the ordinary matter with Bose-Fermi statistics. However, two cases may lead to the holographic energy density if the latter recovers from the geometric mean of UV and IR scales. Hence the dark energy with infinite statistics based on the entropy bound is not an ingredient for deriving the holographic dark energy model. Furthermore, it is shown that the agegraphic dark energy models are the holographic dark energy model with different IR length scales.

Chirality and Cosmic Origin of Life  

E-Print Network (OSTI)

Chirality or the property that distinguishes lefthandedness from righthandedness is an important aspect of the universe, starting from neutrinos, which are lefthanded. Fifteen years ago the author had proposed that life on the earth was formed through a dual process -- several key ingredients being transported from outer space to the earth by comets or meteorites and these in turn interacting with compounds already cooked up in the earth's seas. Several recent observations point to the fact that the amino acids brought out to the earth by meteorites are lefthanded, as in terrestrial life forms. Experiments in the laboratory however throw up equal numbers of lefthanded and righthanded amino acids, what are called racemic mixtures. Not only would the latest observations endorse this dual mode theory of the origin of life, but on the other hand it would point to the key trigger for life processes itself. This is because racemic mixtures are not optically active, unlike the handed or chiral constituents. It is this activity of harnessing solar radiation and converting it into chemical energy, and storing this in the sugar bonds, as in photosynthesis, that characterizes life.

ORIGIN OF LITHIUM ENRICHMENT IN K GIANTS  

Science Conference Proceedings (OSTI)

In this Letter, we report on a low-resolution spectroscopic survey for Li-rich K giants among 2000 low-mass (M {=}3.2) were discovered. A significant finding is that there is a concentration of Li-rich K giants at the luminosity of the clump or red horizontal branch. This new finding is partly a consequence of the fact that our low-resolution survey is the first large survey to include giants well below and above the red giant branch (RGB) bump and clump locations in the H-R diagram. Origin of the lithium enrichment may be plausibly attributed to the conversion of {sup 3}He via {sup 7}Be to {sup 7}Li by the Cameron-Fowler mechanism but the location for the onset of the conversion is uncertain. Two possible opportunities to effect this conversion are discussed: the bump in the first ascent of the RGB and the He-core flash at the tip of the RGB. The finite luminosity spread of the Li-rich giants serves to reject the idea that Li enhancement is, in general, a consequence of a giant swallowing a large planet.

Origin of undesirable cracks during layer transfer  

E-Print Network (OSTI)

We investigate the origin of undesirable transverse cracks often observed in thin films obtained by the layer transfer technique. During this process, two crystals bonded to each other containing a weak plan produced by ion implantation are heated to let a thin layer of one of the material on the other. The level of stress imposed on the film during the heating phase due to the mismatch of thermal expansion coefficients of the substrate and the film is shown to be the relevant parameter of the problem. In particular, it is shown that if the film is submitted to a tensile stress, the microcracks produced by ion implantation are not stable and deviate from their straight trajectory making the layer transfer process impossible. However, if the compressive stress exceeds a threshold value, after layer transfer, the film can buckle and delaminate, leading to transverse cracks induced by bending. As a result, we show that the imposed stress \\sigma_m - or equivalently the heating temperature - must be within the ran...

ON THE ORIGIN OF INTERGRANULAR JETS  

SciTech Connect

We observe that intergranular jets, originating in the intergranular space surrounding individual granules, tend to be associated with granular fragmentation, in particular, with the formation and evolution of a bright granular lane (BGL) within individual granules. The BGLs have recently been identified as vortex tubes by Steiner et al. We further discover the development of a well-defined bright grain located between the BGL and the dark intergranular lane to which it is connected. Signatures of a BGL may reach the lower chromosphere and can be detected in off-band H{alpha} images. Simulations also indicate that vortex tubes are frequently associated with small-scale magnetic fields. We speculate that the intergranular jets detected in the New Solar Telescope (NST) data may result from the interaction between the turbulent small-scale fields associated with the vortex tube and the larger-scale fields existing in the intergranular lanes. The intergranular jets are much smaller and weaker than all previously known jet-like events. At the same time, they appear much more numerous than the larger events, leading us to the speculation that the total energy release and mass transport by these tiny events may not be negligible in the energy and mass-flux balance near the temperature minimum atop the photosphere. The study is based on the photospheric TiO broadband (1.0 nm) filter data acquired with the 1.6 m NST operating at the Big Bear Solar Observatory. The data set also includes NST off-band H{alpha} images collected through a Zeiss Lyot filter with a passband of 0.025 nm.

THE ORIGIN OF THE VIRGO STELLAR SUBSTRUCTURE  

Science Conference Proceedings (OSTI)

We present three-dimensional space velocities of stars selected to be consistent with membership in the Virgo stellar substructure. Candidates were selected from SA 103, a single 40' Multiplication-Sign 40' field from our proper-motion (PM) survey in Kapteyn's Selected Areas (SAs), based on the PMs, Sloan Digital Sky Survey (SDSS) photometry, and follow-up spectroscopy of 215 stars. The signature of the Virgo substructure is clear in the SDSS color-magnitude diagram (CMD) centered on SA 103, and 16 stars are identified that have high Galactocentric-frame radial velocities (V{sub GSR} > 50 km s{sup -1}) and lie near the CMD locus of Virgo. The implied distance to the Virgo substructure from the candidates is 14 {+-} 3 kpc. We derive mean kinematics from these 16 stars, finding a radial velocity V{sub GSR} = 153 {+-} 22 km s{sup -1} and proper motions ({mu}{sub {alpha}}cos {delta}, {mu}{sub {delta}}) = (- 5.24, -0.91) {+-} (0.43, 0.46) mas yr{sup -1}. From the mean kinematics of these members, we determine that the Virgo progenitor was on an eccentric (e {approx} 0.8) orbit that recently passed near the Galactic center (pericentric distance R{sub p} {approx} 6 kpc). This destructive orbit is consistent with the idea that the substructure(s) in Virgo originated in the tidal disruption of a Milky Way satellite. N-body simulations suggest that the entire cloud-like Virgo substructure (encompassing the 'Virgo Overdensity' and the 'Virgo Stellar Stream') is likely the tidal debris remnant from a recently disrupted massive ({approx}10{sup 9} M{sub Sun }) dwarf galaxy. The model also suggests that some other known stellar overdensities in the Milky Way halo (e.g., the Pisces Overdensity and debris near NGC 2419 and SEGUE 1) are explained by the disruption of the Virgo progenitor.

Oceanic Origins of Southwest Tropical Atlantic Biases  

E-Print Network (OSTI)

The SST bias in the tropical Atlantic exists in the early to latest generation of coupled general circulation models. The maximum bias is not on the equator but at 16°S, the cause of which has not been thoroughly studied. Newly released CMIP5 models provide a useful tool to investigate the contributions of different physical processes to the SST bias in this area in the coupled system. We tested three existing mechanisms and found that: 1) there is no significant relationship between the SST bias and surface heat flux bias; 2) deficient coastal upwelling is a contributing but not the sole source of the bias; and 3) the SST bias is correlated with temperature biases in the upstream equatorial region. The Angola-Benguela front is displaced southward by more than 10° in latitude in many CIMP5 models. Due to the huge temperature contrasts on two sides of the front, such a frontal displacement generates a very strong SST bias. The correlation between the SST bias and frontal location error in this region is significant at the 99% level, demonstrating that the SST bias in coupled GCMs is attributable to the models’ inability to reproduce a realistic position of the front and the consequent erroneous advection by the southward Angola current. This is due to both errors in the simulated surface wind field and systematic errors in ocean models. Ocean reanalysis datasets and a high-resolution regional model simulation suffer a similar pattern of SST biases. Although they produce a more realistic ocean circulation than coarser resolution simulations and alleviate some of the severe SST bias near the front, a warm bias overlies on a northward current to the south of the front, which actually comes from the north of the front through a subsurface passage. We identify a strong subsurface temperature bias caused by a too-deep and diffused simulated thermocline along the coast of Angola, originating from the equatorial thermocline, advected by the Angola Current and an undercurrent beneath the Benguela current, and then brought to the surface by the coastal upwelling along the Benguela coast, contributing to the warm SST bias south of the front.

New observations lead us to re-interpret the origin of the sector collapse. We show that it was triggered by failure of active thrust-anticlines in sediments and ignimbrites underlying the volcano. The thrust-anticlines were a result of gravitational spreading of substrata under the volcano load. About 80% of the resulting avalanche deposit is composed of substrata formerly residing under the volcano and in the anticlines. The collapse

Origins and consequences of radiation-induced centrosome aberrations Origins and consequences of radiation-induced centrosome aberrations Sangeetha Vijayakumar, Nisarg Shah, Ignacio Fernandez-Garcia, Mary Helen Barcellos-Hoff Department of Radiation Oncology, New York University School of Medicine, NY, NY. Centrosome aberrations are frequently observed in pre-neoplastic breast lesions and are known to drive chromosomal instability (Lingle et al., 2002). Previous studies from our lab have shown that human mammary epithelial cells exposed to low doses of radiation exhibit centrosome aberrations (CAs) in a dose dependent manner from 10-200 cGy (Maxwell et al., 2008). These data demonstrated that radiation-induced CAs actually precede and generate genomic instability and that TGFβ is a key mediator

On symmetry and topological origin of Weyl particles  

E-Print Network (OSTI)

We suggest that the Weil spinors originate from the multi - component fermion fields. Those fields belong to the unusual theory that, presumably, exists at extremely high energies. In this theory there is no Lorentz symmetry. Moreover, complex numbers are not used in the description of its dynamics. Namely, the one - particle wave functions are real - valued, the functional integral that describes the second - quantised theory does not contain the imaginary unit as well. In the low energy effective theory the two - component Weil spinors appear. Their appearance is related to the Atiyah-Bott-Shapiro construction and to the expansion of the real matrix near the topologically protected nodes in three dimensional momentum space. The complex numbers entering ordinary quantum mechanics emerge together with the Weil fermions. In this pattern gauge fields and gravitational fields appear as certain collective excitations (of the original theory) experienced by the low - energy Weil fermions.

Origin and geochemical evolution of the Michigan basin brine  

Science Conference Proceedings (OSTI)

Chemical and isotopic data were collected on 126 oil field brine samples and were used to investigate the origin and geochemical evolution of water in 8 geologic formations in the Michigan basin. Two groups of brine are found in the basin, the Na-Ca-Cl brine in the upper Devonian formations, and Ca-Na-Cl brine from the lower Devonian and Silurian aged formations. Water in the upper Devonian Berea, Traverse, and Dundee formations originated from seawater concentrated into halite facies. This brine evolved by halite precipitation, dolomitization, aluminosilicate reactions, and the removal of SO{sub 4} by bacterial action or by CaSO{sub 4} precipitation. The stable isotopic composition (D, O) is thought to represent dilution of evapo-concentrated seawater by meteoric water. Water in the lower Devonian Richfield, Detroit River Group, and Niagara-Salina formations is very saline Ca-Na-Cl brine. Cl/Br suggest it originated from seawater concentrated through the halite and into the MgSO{sub 4} salt facies, with an origin linked to the Silurian and Devonian salt deposits. Dolomitization and halite precipitation increased the Ca/Na, aluminosilicate reactions removed K, and bacterial action or CaSO{sub 4} precipitation removed SO{sub 4} from this brine. Water chemistry in the Ordovician Trenton-Black River formations indicates dilution of evapo-concentrated seawater by fresh or seawater. Possible saline end-members include Ordovician seawater, present-day upper Devonian brine, or Ca-Cl brine from the deeper areas in the basin.

The origin of the lost fleet of the mongol empire  

E-Print Network (OSTI)

In 1281 C.E., under the rule of Kublai Khan, the Mongols sent a fleet of more than 4000 vessels to subjugate the island nation of Japan. A powerful typhoon, called kamikaze, dashed the invading fleet into pieces on the shores of Japan and thus saved the nation from foreign rule. Historical sources suggest there were three principal vessel types involved in this event: V-shaped cargo ships for transporting provisions to the front, constructed in China’s Fukien Province; miscellaneous flat and round bottomed vessels made along the Yangtze River; and flat bottomed landing craft from Korea. In the recent past, the remains of the fleet were discovered at the Takashima underwater site in western Japan, unveiling numerous artifacts including weaponry, shipboard items, and sections of hull; however, between 1281 and the late twentieth century the site has seen major disturbances, and the artifacts are often in poor condition. Because the site contains the remains of ships built in China and Korea, the interpretation of the artifacts is also extremely complex. In order to determine the origin of the vessels, a logical framework is necessary. The author has created a timber category database, analyzed methods of joinery, and studied contemporary approaches to shipbuilding to ascertain the origins and types of vessels that composed the Mongol fleet. Although no conclusive statements can be made regarding the origins of the vessels, it appears that historical documents and archaeological evidence correspond well to each other, and that many of the remains analyzed were from smaller vessels built along the Yangtze River Valley. Large, V-shaped cargo ships and the Korean vessels probably represent a small portion of the timbers raised at the Takashima site. As the first research project of its kind in the region, this study is a starting point for understanding the real story of the Mongol invasion of Japan, as well as the history of shipbuilding in East Asia.

Origin of the Temperature Oscillation in Turbulent Thermal Convection  

E-Print Network (OSTI)

We report an experimental study of the three-dimensional spatial structure of the low frequency temperature oscillations in a cylindrical Rayleigh-B\\'{e}nard convection cell. It is found that thermal plumes are not emitted periodically, but randomly and continuously, from the top and bottom plates. We further found that the oscillation of the temperature field does not originate from the boundary layers, but rather is a result of the horizontal motion of the hot ascending and cold descending fluids being modulated by the twisting and sloshing motion of the bulk flow field.

Here, we show that in the cannonball (CB) model of GRBs, the newly discovered correlations have the same simple kinematic origin as those discovered earlier. They all result from the strong dependence of the observed radiations on the Lorentz and Doppler factors of the jet of highly relativistic plasmoids (CBs) that produces the observed radiations by interaction with the medium through which it propagates.

On the origin and evolution of icicle ripples  

E-Print Network (OSTI)

Natural icicles often exhibit ripples about their circumference which are due to a morphological instability. We present an experimental study that explores the origin of the instability, using laboratory-grown icicles. Contrary to theoretical expectations, icicles grown from pure water do not exhibit growing ripples. The addition of a non-ionic surfactant, which reduces the surface tension, does not produce ripples. Instead, ripples emerge on icicles grown from water with dissolved ionic impurities. We find that even very small levels of impurity are sufficient to trigger ripples, and that the growth speed of the ripples increases very weakly with ionic concentration.

Microscopic origin of the second law of thermodynamics  

E-Print Network (OSTI)

We proved when random-variable fluctuations obey the central limit theorem the equality of the uncertainty relation corresponds to the thermodynamic equilibrium state. The inequality corresponds to the thermodynamic non-equilibrium state. The uncertainty relation is a quantum-mechanics expression of the second law of thermodynamics originated in wave-particle duality. Formulas of mean square-deviations changes adjusted by random fluctuations under the minimal uncertainty relation are obtained. Finally, an assumption is made which is waiting for examination. We except phase transitions in our discussion.

On the origin of the anomalous precession of Mercury's perihelion  

E-Print Network (OSTI)

Action at distance in Newtonian physics is replaced by finite propagation speeds in classical post--Newtonian physics. As a result, the differential equations of motion in Newtonian physics are replaced by functional differential equations, where the delay associated with the finite propagation speed is taken into account. Newtonian equations of motion, with post--Newtonian corrections, are often used to approximate the functional differential equations. In ``On the origin of quantum mechanics'', preprint, physics/0505181, May 2005, a simple atomic model based on a functional differential equation which reproduces the quantized Bohr atomic model was presented. The unique assumption was that the electrodynamic interaction has a finite propagation speed. In ``On the origin of the gravitational quantization: The Titius--Bode Law'', preprint, physics/0507072, Jul 2005, a simple gravitational model based on a functional differential equation which gives a gravitational quantification and an explanation of the modified Titius--Bode law is described. Firstly, in this work, we recall the calculations made by Einstein to arrive at the explanation of the anomalous precession of Mercury's perihelion. Secondly, we recover an ancient work of Gerber in 1898 as a precursor of the retarded theories. In this paper Gerber gave an explanation of the anomalous precession of the Mercury's perihelion in terms of a velocity--dependent potential. In this paper an explanation of the anomalous precession of Mercury's perihelion is given in terms of a simple retarded potential, which, at first order, coincides with Gerber's potential, and which agrees with the author's previous works.

Probing the origin of inertia behind spacetime deformation  

E-Print Network (OSTI)

To investigate the origin and nature of inertia, we introduce a new concept of hypothetical 2D, so-called, "master-space" (MS), subject to certain rules. The MS, embedded in the background 4D-spacetime, is an indispensable individual companion to the particle of interest, without relation to every other particle. We argue that a deformation/(distortion of local internal properties) of MS is the origin of inertia. With this perspective in sight, we construct the alternative relativistic theory of inertia (RTI), which allows to compute the relativistic inertial force acting on an arbitrary point-like observer due to its "absolute acceleration". We go beyond the hypothesis of locality with an emphasis on distortion of MS, which allows to improve essentially the standard metric and other relevant geometrical structures related to the noninertial reference frame of an arbitrary accelerated observer. We compute the inertial force exerted on the photon in a gravitating system in the semi-Riemann space. Despite the t...

We compute the inertial force exerted on the photon in a gravitating system in the semi-Riemann space. Despite the totally different and independent physical sources of gravitation and inertia, this approach furnishes justification for the introduction of the principle of equivalence. Consequently, we relate the inertia effects to the more general post-Riemannian geometry. We derive a general expression of the relativistic inertial force exerted on the extended spinning body moving in the Rieman-Cartan space.

A COMPOUND MODEL FOR THE ORIGIN OF EARTH'S WATER  

Science Conference Proceedings (OSTI)

One of the most important subjects of debate in the formation of the solar system is the origin of Earth's water. Comets have long been considered as the most likely source of the delivery of water to Earth. However, elemental and isotopic arguments suggest a very small contribution from these objects. Other sources have also been proposed, among which local adsorption of water vapor onto dust grains in the primordial nebula and delivery through planetesimals and planetary embryos have become more prominent. However, no sole source of water provides a satisfactory explanation for Earth's water as a whole. In view of that, using numerical simulations, we have developed a compound model incorporating both the principal endogenous and exogenous theories, and investigating their implications for terrestrial planet formation and water delivery. Comets are also considered in the final analysis, as it is likely that at least some of Earth's water has cometary origin. We analyze our results comparing two different water distribution models, and complement our study using the D/H ratio, finding possible relative contributions from each source and focusing on planets formed in the habitable zone. We find that the compound model plays an important role by showing greater advantage in the amount and time of water delivery in Earth-like planets.

Comment on Origin of Groundwater Discharge at Fall River Springs  

SciTech Connect

I'm writing at the request of the Pit River Tribe to offer my professional opinion as a geochemist regarding the origin of groundwater discharge at the Fall River Springs, Shasta Co., California. In 1997, I conducted a study of the large volume cold springs associated with the Cascade Volcanoes in northern California, in collaboration with one of my colleagues. This work was published as a Lawrence Livermore National Laboratory report (Davisson and Rose, 1997). The Fall River Springs emerge from the distal end of the Giant Crater Lava Field, a laterally extensive basalt flow that stretches from the southern flank of Medicine Lake Volcano southward for a distance of 40 km. Both Medicine Lake Volcano and the Giant Crater Lava Field have virtually no surface water drainages. Precipitation that falls in these areas is inferred to seep into fractures in the rock, where it is carried down gradient under the force of gravity. Mean annual precipitation rates on Medicine Lake Volcano and the Giant Crater Lava field are adequate to account for the {approx}1200 ft{sup 3}/sec discharge of the Fall River Springs. To evaluate the origin of the springs using geochemical methods, water samples were collected from the Fall River Springs and the Medicine Lake highlands and analyzed for oxygen and hydrogen isotope ratios. The isotope ratios measured for a groundwater sample are diagnostic of the average composition of the precipitation from which the water was derived. The isotope ratios of rain and snow also vary systematically with elevation, such that groundwater derived from recharge at higher elevations can be distinguished from that which originated at lower elevations. The stable isotope data for the Fall River Springs are consistent with groundwater recharge on the Medicine Lake Volcano and adjacent lava field. Mass balance calculations suggest that approximately half of the Fall River Springs flow is derived from the volcanic edifice. Rose and Davisson (1996) showed that the large volume cold springs associated with the Cascade Volcanoes commonly contain dissolved CO{sub 2} that originated from the volcanoes. This volcanic CO{sub 2} component is readily identified from carbon-14 measurements of the water. Carbon-14 analyses of the Fall River samples indicate that at least 27% of the dissolved inorganic carbon in the springs was derived from a volcanic CO{sub 2} source. Such a large volcanic CO{sub 2} flux requires that the groundwater supplying flow to the Fall River Springs must originate from a volcano where magma degassing is actively occurring. Given the hydrogeologic configuration of the Fall River aquifer system, it appears that the Medicine Lake Volcano is the only likely source of the volcanic CO{sub 2}. These data independently confirm the Medicine Lake highlands as a significant recharge source for the Fall River Springs. Moreover, these data indicate that groundwater recharge occurring on Medicine Lake Volcano must interact with a CO{sub 2} volatile phase derived from the geothermal system beneath the volcano. The lack of hot springs on Medicine Lake Volcano suggests that the geothermal system underlying the volcano is relatively tightly sealed. Nevertheless, it is probable that the geothermal fluid originates from precipitation falling on the volcanic edifice. This is the same water that supplies an important fraction of the Fall River Spring discharge. The source of the geothermal fluid can be evaluated using stable isotopes. The oxygen isotope signature of the geothermal fluid may have been modified by high temperature oxygen isotope exchange with the surrounding rock, but the hydrogen isotope signature should still be diagnostic of the origin of the fluid.

Origins of the slow and the ubiquitous fast solar wind  

E-Print Network (OSTI)

We present in this Letter the first coordinated radio occultation measurements and ultraviolet observations of the inner corona below 5.5 Rs, obtained during the Galileo solar conjunction in January 1997, to establish the origin of the slow solar wind. Limits on the flow speed are derived from the Doppler dimming of the resonantly scattered componentof the oxygen 1032 A and 1037 A lines as measured with the UltraViolet Coronagraph Spectrometer (UVCS) on the Solar and Heliospheric Observatory (SOHO). White light images of the corona from the Large Angle Spectroscopic Coronagraph (LASCO) on SOHO taken simultaneously are used to place the Doppler radio scintillation and ultraviolet measurements in the context ofcoronal structures. These combined observations provide the first direct confirmation of the view recently proposed by Woo and Martin (1997) that the slow solar wind is associated with the axes, also known as stalks, of streamers. Furthermore, the ultraviolet observations also show how the fast solar wind...

The Constitutional Origins of the President's Foreign Affairs Power  

E-Print Network (OSTI)

The question of the executive’s authority over foreign affairs has been debated constantly over the life of the Constitution. Rather than try to discern the answer to this question from only the well-known Framers, this scholarly endeavor proposes to unlock the original understanding of the Constitution to the “citizens, polemicists, and convention delegates who participated in one way or another in ratification.” Recent scholarship in the nature of the executive’s foreign affair power has suffered from a lesser degree of scrutiny than other constitutional subjects. Few scholars have addressed the original source of authority and legitimacy of the Constitution—its ratification—as a means of determining whether the modern presidency continues to abuse or respect the powers the Constitution has invested in it. Those that have looked to the historical context of the Constitution’s ratification and believe that public sentiment toward the executive was more characterized by fear rather than want of energy have reached their conclusion because of select sampling from an extraordinary era in American constitutionalism. The research will be divided among three major historical periods of American constitutionalism: (1) the pre-revolutionary era (early 1700s until 1775) while America was still comprised of 13 British colonies and most constitutional concerns where focused on Parliament’s abuses of power and the Executive’s complicity; (2) the executive interregnum (1775 until the early 1780s) wherein the American public feared executive authority and experimented with a weak executive; and (3) the period of legislative fear (early 1780s to 1790s) that acted as a catalyst for James Madison, Alexander Hamilton, and others to restore an energetic executive.

Cosmic Rays during BBN as Origin of Lithium Problem  

E-Print Network (OSTI)

There may be non-thermal cosmic rays during big-bang nucleosynthesis (BBN) epoch (dubbed as BBNCRs). This paper investigated whether such BBNCRs can be the origin of Lithium problem or not. It can be expected that BBNCRs flux will be small in order to keep the success of standard BBN (SBBN). With favorable assumptions on the BBNCR spectrum between 0.09 -- 4 MeV, our numerical calculation showed that extra contributions from BBNCRs can account for the $^7$Li abundance successfully. However $^6$Li abundance is only lifted an order of magnitude, which is still much lower than the observed value. As the deuteron abundance is very sensitive to the spectrum choice of BBNCRs, the allowed parameter space for the spectrum is strictly constrained. We should emphasize that the acceleration mechanism for BBNCRs in the early universe is still an open question. For example, strong turbulent magnetic field is probably the solution to the problem. Whether such a mechanism can provide the required spectrum deserves further studies.

Towards a Theory for the Origin of Neptune Trojans  

E-Print Network (OSTI)

The newly discovered class of Neptune Trojans promises to test theories of planet formation by coagulation. Neptune Trojans resembling the prototypical object 2001 QR322 (``QR'')--whose radius of ~100 km is comparable to that of the largest Jupiter Trojan--may outnumber their Jovian counterparts by a factor of ~20. We develop and test three theories for the origin of large Neptune Trojans: pull-down capture, direct collisional emplacement, and in situ accretion. These theories are staged after Neptune's orbit anneals: after dynamical friction eliminates any large orbital eccentricity and after the planet ceases to migrate. We discover that seeding the 1:1 resonance with debris from planetesimal collisions and having the seed particles accrete in situ naturally reproduces the inferred number of QR-sized Trojans. We analyze accretion in the Trojan sub-disk by applying the two-groups method, accounting for kinematics specific to the resonance. A Trojan sub-disk comprising decimeter-sized seed particles and havin...

ON A GIANT IMPACT ORIGIN OF CHARON, NIX, AND HYDRA  

SciTech Connect

It is generally believed that Charon was formed as a result of a large, grazing collision with Pluto that supplied the Pluto-Charon system with its high angular momentum. It has also been proposed that Pluto's small outer moons, Nix and Hydra, formed from debris from the Charon-forming impact, although the viability of this scenario remains unclear. Here I use smooth particle hydrodynamics impact simulations to show that it is possible to simultaneously form an intact Charon and an accompanying debris disk from a single impact. The successful cases involve colliding objects that are partially differentiated prior to impact, having thin outer ice mantles overlying a uniform composition rock-ice core. The composition of the resulting debris disks varies from a mixture of rock and ice (similar to the bulk composition of Pluto and Charon) to a pure ice disk. If Nix and Hydra were formed from such an impact-generated disk, their densities should be less than or similar to that of Charon and Pluto, and the small moons could be composed entirely of ice. If they were instead formed from captured material, a mixed rock-ice composition and densities similar to that of Charon and Pluto would be expected. Improved constraints on the properties of Nix and Hydra through occultations and/or the New Horizons encounter may thus help to distinguish between these two modes of origin, particularly if the small moons are found to have ice-like densities.

Host dynamics and origin of Palomar-Green QSOs  

E-Print Network (OSTI)

We present host-galaxy velocity dispersions of 12 local (mainly Palomar-Green) quasi-stellar objects (QSOs) measured directly from the stellar CO absorption features in the H band. The mean bulge velocity dispersion of the QSOs in our sample is 186 km/s with a standard deviation of 24 km/s. The measurement of the stellar velocity dispersion in QSOs enables us to place them on observational diagrams such as the local black-hole mass to bulge-velocity-dispersion relation and the fundamental plane of early-type galaxies. Concerning the former relation, these QSOs have higher black hole masses than most Seyfert 1 AGNs with similar velocity dispersions. On the fundamental plane, PG QSOs are located between the regions occupied by moderate-mass and giant ellipticals. The QSO bulge and black hole masses, computed from the stellar velocity dispersions, are of order 10^11 M_sun and 10^8 M_sun respectively. The Eddington efficiency of their black holes is on average 0.25, assuming that all of the bolometric luminosity originates from the active nucleus. Our data are consistent with other lines of evidence that Palomar-Green QSOs are related to galaxy mergers with gas-rich components and that they are formed in a manner similar to the most massive Ultraluminous Infrared Galaxies, regardless of their far-infrared emission. However, PG QSOs seem to have smaller host dispersions and different formation mechanisms than QSOs with supermassive black holes of 5x10^8-10^9 M_sun that accrete at low rates and reside in massive spheroids.

The multiverse and the origin of our universe  

E-Print Network (OSTI)

The multiverse is a hierarchy in the number of universes, increasing stepwise towards infinity. It is an evolutionary system, in which universes survive only near critical mass. That mass is actually a factor of 1.94 less than the critical mass, and this is found to be consistent with the baryon density inferred from nucleosynthesis in our universe; it is also precisely verified as a cosmological effect. That factor seems to have originated in the multiverse for causing intersecting expansions of its universes, such that mixing occurs of debris from aging galaxies (over proton-decaying time scales). It follows that there is an inter-universal medium (IUM), probably having the demand of new universes in balance with the supply of dark radiation and sub-atomic particles from the decaying galaxies. The mixing causes the universes to have the same quantum, relativity, gravity, and particle physics as our universe. The making of a universe from the radiation and sub-atomic particles occurs through re-vitalizing the protons, and other particles as well, by gravitational energy obtained in accretion of the IUM. This process therefore begins wherever the IUM space density reaches proton density, near 10 E18 kg m E-3. The process continues quietly as the sweeping-up and gravitational accretion proceeds, until the near-critical mass is reached. Some of the IUM debris must also be pervading our present universe, steadily or in partially accreted lumps. The model therefore predicts that the IUM sub-atomic particles appear as our dark matter, and its radiation component as our dark energy, both near 0 K temperatures. The dark energy may cause expansion phenomena, in addition to the above non-flatness expansion, from an accretion lump that arrived at our universe at age near 9 x 10 E9 y.

MULTIPLE-PLANET SCATTERING AND THE ORIGIN OF HOT JUPITERS  

SciTech Connect

Doppler and transit observations of exoplanets show a pile-up of Jupiter-size planets in orbits with a 3 day period. A fraction of these hot Jupiters have retrograde orbits with respect to the parent star's rotation, as evidenced by the measurements of the Rossiter-McLaughlin effect. To explain these observations we performed a series of numerical integrations of planet scattering followed by the tidal circularization and migration of planets that evolved into highly eccentric orbits. We considered planetary systems having three and four planets initially placed in successive mean-motion resonances, although the angles were taken randomly to ensure orbital instability in short timescales. The simulations included the tidal and relativistic effects, and precession due to stellar oblateness. Our results show the formation of two distinct populations of hot Jupiters. The inner population (Population I) is characterized by semimajor axis a < 0.03 AU and mainly formed in the systems where no planetary ejections occurred. Our follow-up integrations showed that this population was transient, with most planets falling inside the Roche radius of the star in <1 Gyr. The outer population of hot Jupiters (Population II) formed in systems where at least one planet was ejected into interstellar space. This population survives the effects of tides over >1 Gyr and fits nicely the observed 3 day pile-up. A comparison between our three-planet and four-planet runs shows that the formation of hot Jupiters is more likely in systems with more initial planets. Due to the large-scale chaoticity that dominates the evolution, high eccentricities and/or high inclinations are generated mainly by close encounters between the planets and not by secular perturbations (Kozai or otherwise). The relative proportion of retrograde planets seems of be dependent on the stellar age. Both the distribution of almost aligned systems and the simulated 3 day pile-up also fit observations better in our four-planet simulations. This may suggest that the planetary systems with observed hot Jupiters were originally rich in the number of planets, some of which were ejected. In a broad perspective, our work therefore hints on an unexpected link between the hot Jupiters and recently discovered free floating planets.

Secretary Chu's Message about Forrestal Electric Metering  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

0 0 Dear Colleagues, The Department of Energy has a responsibility and an opportunity to lead by example in promoting sustainable energy practices. As many of you have heard me say, energy efficiency is one of our best and most immediate opportunities to save energy, cut utility bills and decrease carbon pollution. I want to thank you for the steps many of you have already taken to reduce energy consumption. Today, I'm asking all employees at the Forrestal Building to take these efforts to the next level by participating in a competition to save money by saving energy. We recently divided the Forrestal complex into five zones and installed electric meters to measure the daily electricity consumption of overhead lights and power outlets in each zone. You've probably seen

The origin of $^{60}$Fe and other short-lived radionuclides in the early solar system  

E-Print Network (OSTI)

Establishing the origin of short-lived radionuclides (SLRs) with half-lives $\\leq$ 100 Myr has important implications for the astrophysical context of our Sun's birth place. We review here the different origins proposed for the variety of SLRs present in the solar accretion disk 4.57 Ga ago. Special emphasis is given to an enhanced Galactic background origin for $^{60}$Fe which was inherited from several supernovae belonging to previous episodes of star formation, rather than from a nearby, contemporaneous supernova.

The origin of high-temperature zones in vapor-dominated geothermal systems  

DOE Green Energy (OSTI)

Vapor-dominated geothermal systems are proposed to originate by downward extension (by the ''heat pipe'' mechanism) into hot dry fractured rock above a large cooling igneous intrusion. High temperature zones found by drilling are shallow parts of the original hot dry rock where the penetration of the vapor reservoir was limited, and hot dry rock may extend under much of these reservoirs. An earlier hot water geothermal system may have formed during an early phase of the heating episode.

Multicellular Basis for the Origination of Blast Crisis in Chronic Multicellular Basis for the Origination of Blast Crisis in Chronic Myeloid Leukemia Philip Hahnfeldt Tufts University School of Medicine Abstract Among radiation-induced cancers, some leukemias, including chronic myeloid leukemia (CML) have especially high excess relative risks. CML, sporadic or radiogenic, is also thought to be comparatively very well understood. Accordingly, CML is considered an important model for assessing radiogenic cancer risk. CML is characterized by a specific chromosome translocation, the BCR-ABL fusion gene, and it has been widely postulated that an advanced stage, CML blast crisis originates mainly via cell-autonomous mechanisms such as secondary mutations or genomic instability. However, there is growing evidence that intercellular interactions can play a critical role

Crystal Structure of the Simian Virus 40 Large T-Antigen Origin-Binding Domain  

Science Conference Proceedings (OSTI)

The origins of replication of DNA tumor viruses have a highly conserved feature, namely, multiple binding sites for their respective initiator proteins arranged as inverted repeats. In the 1.45- Angstroms crystal structure of the simian virus 40 large T-antigen (T-ag) origin-binding domain (obd) reported herein, T-ag obd monomers form a left-handed spiral with an inner channel of 30 Angstroms having six monomers per turn. The inner surface of the spiral is positively charged and includes residues known to bind DNA. Residues implicated in hexamerization of full-length T-ag are located at the interface between adjacent T-ag obd monomers. These data provide a high-resolution model of the hexamer of origin-binding domains observed in electron microscopy studies and allow the obd's to be oriented relative to the hexamer of T-ag helicase domains to which they are connected.

Origin of Tumor Recurrence After Intensity Modulated Radiation Therapy for Oropharyngeal Squamous Cell Carcinoma  

Science Conference Proceedings (OSTI)

Purpose: To model locoregional recurrences of oropharyngeal squamous cell carcinomas (OSCC) treated with primary intensity modulated radiation therapy (IMRT) in order to find the origins from which recurrences grow and relate their location to original target volume borders. Methods and Materials: This was a retrospective analysis of OSCC treated with primary IMRT between January 2002 and December 2009. Locoregional recurrence volumes were delineated on diagnostic scans and coregistered rigidly with treatment planning computed tomography scans. Each recurrence was analyzed with two methods. First, overlapping volumes of a recurrence and original target were measured ('volumetric approach') and assessed as 'in-field', 'marginal', or 'out-field'. Then, the center of mass (COM) of a recurrence volume was assumed as the origin from where a recurrence expanded, the COM location was compared with original target volume borders and assessed as 'in-field', 'marginal', or 'out-field'. Results: One hundred thirty-one OSCC were assessed. For all patients alive at the end of follow-up, the mean follow-up time was 40 months (range, 12-83 months); 2 patients were lost to follow-up. The locoregional recurrence rate was 27%. Of all recurrences, 51% were local, 23% were regional, and 26% had both local and regional recurrences. Of all recurrences, 74% had imaging available for assessment. Regarding volumetric analysis of local recurrences, 15% were in-field gross tumor volume (GTV), and 65% were in-field clinical tumor volume (CTV). Using the COM approach, we found that 70% of local recurrences were in-field GTV and 90% were in-field CTV. Of the regional recurrences, 25% were volumetrically in-field GTV, and using the COM approach, we found 54% were in-field GTV. The COM of local out-field CTV recurrences were maximally 16 mm outside CTV borders, whereas for regional recurrences, this was 17 mm. Conclusions: The COM model is practical and specific for recurrence assessment. Most recurrences originated in the GTV. This suggests radioresistance in certain tumor parts.

Origins and consequences of radiation–induced centrosome aberrations Origins and consequences of radiation–induced centrosome aberrations Sangeetha Vijayakumar New York University School of Medicine Abstract Centrosome aberrations are frequently observed in pre-neoplastic breast lesions and are known to drive chromosomal instability (Lingle et al., 2002). Previous studies from our lab have shown that human mammary epithelial cells exposed to low doses of radiation exhibit centrosome aberrations (CAs) in a dose dependent manner from 10-200 cGy (Maxwell et al., 2008). These data demonstrated that radiation-induced CAs actually precede and generate genomic instability and that TGFβ is a key mediator of genomic surveillance by eliminating genomically unstable cells through p53-dependent apoptosis. While high dose radiation has been shown to cause centrosome aberrations

The behavior and origin of the excess wing in DEET (N,N-diethyl-3-methylbenzamide)  

Science Conference Proceedings (OSTI)

Broadband dielectric spectroscopy along with a high pressure technique and quantum-mechanical calculations are employed to study in detail the behavior and to reveal the origin of the excess wing (EW) in neat N,N-diethyl-3-methylbenzamide (DEET). Our analysis of dielectric spectra again corroborates the idea that the EW is a hidden b-relaxation peak. Moreover, we found that the position frequency of the b peak corresponds to the position of the primitive relaxation of the Coupling Model. We also studied the possible intramolecular rotations in DEET by means of DFT calculation. On that basis we were able to describe the EW as the JG b-relaxation and find the possible origin of the g-relaxation visible in DEET dielectric spectra at very low temperatures.

Perfectly elastic collisions as origin of quantum states of superconductivity and magnetic order  

E-Print Network (OSTI)

One of the most interesting properties of solid materials is the ability to form different collective quantum states, such as superconductivity and magnetic order. This paper presents a model of perfectly elastic collisions (p.e.c.) as the universal origin of these collective quantum states. The superb agreement between calculated values and experimental data for critical temperatures, moreover, the explanation of the isotope effect in superconductivity and magnetic order confirms that this model successfully describes these two quantum states.

The traditional way of defining a local measure of chemical hardness has several drawbacks, which undermine the applicability of that local hardness concept. We propose a new approach to this problem, by originating a local chemical potential, a corresponding local hardness, and local hyperhardnesses, from a local energy concept. A chemical potential kernel is also defined, by which a recently proposed alternative local chemical potential and local hardness concept can also be incorporated into this scheme of local reactivity indices.

Origin of Compact Triangular Islands in Metal-on-Metal Growth  

Science Conference Proceedings (OSTI)

The microscopic origin of compact triangular islands on close-packed surfaces is identified using kinetic Monte Carlo simulations with energy barriers obtained from density-functional calculations. In contrast to earlier accounts, corner diffusion anisotropy is found to control the shape of compact islands at intermediate temperatures. We rationalize the correlation between the orientation of dendrites grown at low temperatures and triangular islands grown at higher temperatures, and explain why in some systems dendrites grow fat before turning compact.

The Irradiation Origin of Beryllium Radioisotopes and Other Short-lived Radionuclides  

E-Print Network (OSTI)

Two explanations exist for the short-lived radionuclides present in the solar system when the CAIs first formed. They originated either from the ejecta of a supernova or by the in situ irradiation of nebular dust by energetic particles. With a half-life of only 53 days, Beryllium-7 is then the key discriminant, since it can be made only by irradiation. We calculate the yield of Be-7. Within model uncertainties associated mainly with nuclear cross sections, we obtain agreement with the experimental value. Moreover, if Be-7 and Be-10 have the same origin, the irradiation time must be short. The x-wind model provides a natural astrophysical setting that gives the requisite conditions. The decoupling of the Al-26 and Be-10 observed in some rare CAIs receives a quantitative explanation when rare gradual events are considered. Finally, we show that the presence of supernova-produced Fe-60 in the solar accretion disk does not necessarily mean that other short-lived radionuclides have a stellar origin.

Origin of elevated water levels encountered in Pahute Mesa emplacement boreholes: Preliminary investigations  

SciTech Connect

The presence of standing water well above the predicted water table in emplacement boreholes on Pahute Mesa has been a recurring phenomenon at the Nevada Test Site (NTS). If these levels represent naturally perched aquifers, they may indicate a radionuclide migration hazard. In any case, they can pose engineering problems in the performance of underground nuclear tests. The origin of these elevated waters is uncertain. Large volumes of water are introduced during emplacement drilling, providing ample source for artificially perched water, yet elevated water levels can remain constant for years, suggesting a natural origin instead. In an effort to address the issue of unexpected standing water in emplacement boreholes, three different sites were investigated in Area 19 on Pahute Mesa by Desert Research Institute (DRI) staff from 1990-93. These sites were U-19az, U-19ba, and U-19bh. As of this writing, U-19bh remains available for access; however, nuclear tests were conducted at the former two locations subsequent to this investigations. The experiments are discussed in chronological order. Taken together, the experiments indicate that standing water in Pahute Mesa emplacement holes originates from the drainage of small-volume naturally perched zones. In the final study, the fluids used during drilling of the bottom 100 m of emplacement borehole U-19bh were labeled with a chemical tracer. After hole completion, water level rose in the borehole, while tracer concentration decreased. In fact, total mass of tracer in the borehole remained constant, while water levels rose. After water levels stabilized in this hole, no change in tracer mass was observed over two years, indicating that no movement of water out of the borehole is taking place (as at U- 19ba). Continued labeling tests of standing water are recommended to confirm the conclusions made here, and to establish their validity throughout Pahute Mesa.

GRB 110721A: PHOTOSPHERE 'DEATH LINE' AND THE PHYSICAL ORIGIN OF THE GRB BAND FUNCTION  

Science Conference Proceedings (OSTI)

The prompt emission spectra of gamma-ray bursts (GRBs) usually have a dominant component that is well described by a phenomenological Band function. The physical origin of this spectral component is debated. Although the traditional interpretation is synchrotron radiation of non-thermal electrons accelerated in internal shocks or magnetic dissipation regions, the growing trend within the community is to interpret this component as modified thermal emission from a dissipative photosphere of a GRB fireball. We analyze the time-dependent spectrum of GRB 110721A detected by the Fermi Gamma-Ray Burst Monitor and Large Area Telescope, and pay special attention to the rapid evolution of the peak energy E{sub p} . We define a 'death line' of thermally dominated dissipative photospheric emission in the E{sub p} -L plane, and show that E{sub p} of GRB 110721A at the earliest epoch has a very high E{sub p} {approx} 15 MeV that is beyond the 'death line'. Together with the finding that an additional 'shoulder' component exists in this burst that is consistent with a photospheric origin, we suggest that at least for some bursts, the Band component is not from a dissipative photosphere, but must invoke a non-thermal origin (e.g., synchrotron or inverse Compton) in the optically thin region of a GRB outflow. We also suggest that the rapid hard-to-soft spectral evolution is consistent with the quick discharge of magnetic energy in a magnetically dominated outflow in the optically thin region.

Effects of seed origin and irrigation on survival and growth of transplanted shrubs  

SciTech Connect

Revegetation is difficult in the Mojave Desert due to limited, erratic precipitation and extreme temperatures. Establishing plant cover by transplanting native shrubs is known to be a promising technique, but many questions still remain regarding its use on a large operational scale. A study was initiated on the US Department of Energy Nevada Test Site (NTS) to determine the effects of seed origin and irrigation on survival and growth of transplanted shrubs. Plants of three species (Larrea tridentata, Ambrosia dumosa, and Atriplex canescens) were grown in a greenhouse and hardened outdoors. Plants of all three species were produced from two seed sources: (1) seed collected from the NTS (Mojave Desert), and (2) commercially available seed collected from outside the NTS. One-year-old containerized plants (180 of each species) were transplanted to a site on the NTS and irrigated with two liters of water at one of the following frequencies: (1) at time of planting only, (2) at time of planting and monthly during the first growing season, and (3) at time of planting and twice monthly during the first growing season. After 16 months, survival of all species was generally greater than 80% and was unaffected by irrigation treatments. Survival of fourwing saltbush was significantly greater from local versus non-local seed. Survival of bursage and creosotebush was generally unaffected by seed origin. Shrub volumes regardless of species or seed origin increased during the first growing season, and then decreased during the second growing season. Shrub volumes for fourwing saltbush were significantly greater for shrubs from local versus non-local seed.

Diversity and Origin of 2:1 Orbital Resonances in Extrasolar Planetary Systems  

E-Print Network (OSTI)

(Abridged) A diversity of 2:1 resonance configurations can be expected in extrasolar planetary systems, and their geometry can provide information about the origin of the resonances. Assembly during planet formation by the differential migration of planets due to planet-disk interaction is one scenario for the origin of mean-motion resonances in extrasolar planetary systems. The stable 2:1 resonance configurations that can be reached by differential migration of planets with constant masses and initially coplanar and nearly circular orbits are (1) anti-symmetric configurations with the mean-motion resonance variables theta_1 and theta_2 (in deg.) librating about 0 and 180, respectively (as in the Io-Europa pair), (2) symmetric configurations with both theta_1 and theta_2 librating about 0 (as in the GJ 876 system), and (3) asymmetric configurations with theta_1 and theta_2 librating about angles far from either 0 or 180. There are, however, stable 2:1 resonance configurations with symmetric (theta_1 = theta_2 = 0), asymmetric, and anti-symmetric (theta_1 = 180 and theta_2 = 0) librations that cannot be reached by differential migration of planets with constant masses and initially coplanar and nearly circular orbits. If real systems with these configurations are ever found, their origin would require (1) a change in the planetary mass ratio m_1/m_2 during migration, (2) a migration scenario involving inclination resonances, or (3) multiple-planet scattering in crowded planetary systems. We find that the asymmetric configurations with large e_2 and the theta_1 = 180 and theta_2 = 0 configurations have intersecting orbits and that the theta_1 = theta_2 = 0 configurations with e_1 > 0.714 have prograde periapse precessions.

Unraveling the origins of electromechanical response in mixed-phase Bismuth Ferrite  

SciTech Connect

The origin of giant electromechanical response in a mixed-phase rhombohedral-tetragonal BiFeO3 thin film is probed using sub-coercive scanning probe microscopy based multiple-harmonic measurements. Significant contributions to the strain arise from a second-order harmonic response localized at the phase boundaries. Strain and dissipation data, backed by thermodynamic calculations suggest that the source of the enhanced electromechanical response is the motion of phase boundaries. These findings elucidate the key role of labile phase boundaries, both natural and artificial, in achieving thin films with giant electromechanical properties.

The origin of organic pollutants from the combustion of alternative fuels: Phase 5/6 report  

DOE Green Energy (OSTI)

As part of the US Department of Energy National Renewable Energy Laboratory program on alternative automotive fuels, the subcontractor has been conducting studies on the origin and fate of organic pollutants from the combustion of alternative fuels. Laboratory experiments were conducted simulating cold start of four alterative fuels (compressed natural gas, liquefied petroleum gas, methanol-gasoline mix, and ethanol-gasoline mix) using a commercial three-way catalyst under fuel-lean conditions. This report summarizes the results of these experiments. It appears that temperature of the catalyst is a more important parameter for fuel conversion and pollutant formation than oxygen concentration or fuel composition.

The Williston basin of North Dakota, Montana, South Dakota, and south-central Canada (Manitoba and Saskatchewan) is a major producer of oil and gas, lignite, and potash. Oil exploration and development in the United States portion of the Williston basin since 1972 have given impetus to restudy basin evolution and geologic controls for energy-resource locations. Consequently, oil production in North Dakota has jumped from a nadir of 19 million bbl in 1974 to 40 million bbl in 1980. The depositional origin of the basin and the major structural features of the basin are discussed. (JMT)

Photohadronic Origin of the TeV-PeV Neutrinos Observed in IceCube  

E-Print Network (OSTI)

We perform an unbiased search of the origin of the recently observed 28 events above ~30 TeV in the IceCube neutrino observatory, assuming that these are (apart from the atmospheric background) of astrophysical origin produced by photohadronic interactions. Instead of relying on the normalization of the neutrino flux, we demonstrate that spectral shape and flavor composition can be used to constrain or identify the source class. In order to quantify our observations, we use a model where the target photons are produced by the synchrotron emission of co-accelerated electrons, and we include magnetic field effects on the secondary muons, pions, and kaons. We find that the lack of observed events with energies much larger than PeV points towards sources with strong magnetic fields, which do not exhibit a direct correlation between highest cosmic ray and neutrino energies. While the simplest AGN models with efficient proton acceleration plausibly describe the current data at about the 3sigma confidence level, we show that IceCube can rule out that the observed neutrinos stem from the sources of the ultra-high energy cosmic rays with a factor of ten increased statistics at more than 5sigma if the current observations are confirmed. A possible caveat are sources with strong magnetic fields and high Lorentz factors, such as magnetic energy dominated GRBs.

ORIGINAL ARTICLE Low Motor Assessment: A Comparative Pilot Study with Young Children With and Without Motor  

E-Print Network (OSTI)

# The Author(s) 2009. This article is published with open access at Springerlink.com Abstract Most of the developmental instruments that measure cognitive development in children rely heavily on fine motor skills, especially for young children whose language skills are not yet well developed. This is problematic when evaluating the cognitive development of young children with motor impairment. The purpose of this study is to assess the need for a Low Motor adapation of a standardized instrument when testing children with motor impairment. To accomplish this, we have adapted the procedures, item instructions and play material of a widely used and standardized instrument, the Bayley Scales of Infant Development-Second Edition (BSID-II, Bayley 1993). The Original and the Low Motor versions were administered to 20 children experiencing typical development and 19 children with motor impairment within a period of two weeks. Results showed that children with motor impairments scored significantly higher on the Low Motor version of the Bayley Mental Scale than on the Original version: a difference of between 5 and 10 points when the score is expressed in terms of a developmental index score. Results from children with typical development support the assumption that item content and difficulty remain unchanged in the Low Motor version.

Multiwavelength Study on Solar and Interplanetary Origins of the Strongest Geomagnetic Storm of Solar Cycle 23  

E-Print Network (OSTI)

We study the solar sources of an intense geomagnetic storm of solar cycle 23 that occurred on 20 November 2003, based on ground- and space-based multiwavelength observations. The coronal mass ejections (CMEs) responsible for the above geomagnetic storm originated from the super-active region NOAA 10501. We investigate the H-alpha observations of the flare events made with a 15 cm solar tower telescope at ARIES, Nainital, India. The propagation characteristics of the CMEs have been derived from the three-dimensional images of the solar wind (i.e., density and speed) obtained from the interplanetary scintillation data, supplemented with other ground- and space-based measurements. The TRACE, SXI and H-alpha observations revealed two successive ejections (of speeds ~350 and ~100 km/s), originating from the same filament channel, which were associated with two high speed CMEs (~1223 and ~1660 km/s, respectively). These two ejections generated propagating fast shock waves (i.e., fast drifting type II radio bursts) ...

The Multiverse Origin of our Physics does without Strings, Big Bang, Inflation, or Parallel Universes  

E-Print Network (OSTI)

Evolution needs long times and large numbers of samples or species. Our finely tuned physics can therefore not have evolved during the fast changes of a single Big-Bang universe, but the cosmological scales for time and for the number of universes in the multiverse satisfy that condition. Planck and Chandrasekhar equations show that multiverse. A variety of observations show the origin of our physics. The multiverse is being fed by the debris of its decaying universes, which is transported on the accelerated expansion. New universes originate from clouds of that debris, which is re-energized by the gravity at the center of the cloud when the proton density is reached. That epoch occurs much later than a Big Bang. It marks the beginning of our universe with a photon burst, which may have been observed by spacecraft as the radiation signature with a wider curvature than that of the cosmic background radiation. A test for black holes, published by Karl Schwarzschild in 1916, also confirms that beginning.

Origin of fluid inclusion water in bedded salt deposits, Palo Duro Basin, Texas  

DOE Green Energy (OSTI)

Salt horizons in the Palo Duro Basin being considered for repository sites contain fluid inclusions which may represent connate water retained in the salt from the time of original salt deposition and/or external waters which have somehow penetrated the salt. The exact origin of this water is important to the question of whether or not internal portions of the salt deposit have been, and are likely to be, isolated from the hydrosphere for long periods of time. The /sup 18/O//sup 16/O and D/H ratios measured for water extracted from solid salt samples show the inclusions to be dissimilar in isotopic composition to meteoric waters and to formation waters above and below the salt. The fluid inclusions cannot be purely external waters which have migrated into the salt. The isotope data are readily explained in terms of mixed meteoric-marine connate evaporite waters which date back to the time of deposition and early diagenesis of the salt (>250 million years). Any later penetration of the salt by meteoric waters has been insufficient to flush out the connate brines.

On the origin of microcraters on the surface of ion beam bombardedplant cell walls  

SciTech Connect

Ion bombardment of plant and bacterial cellular material has recently been used as a tool for the transfer of exogenous DNA macromolecules into the cell interior region. The precise mechanism that leads to the transfer of macromolecules through the cell envelope is not yet clear, however it has been observed that the ion bombardment is accompanied by the formation of ''microcraters'' on the cell wall, and it is possible that these features provide channels for the macromolecule transfer. Thus the nature and origin of the microcraters is of importance to understanding the DNA transfer phenomenon as well as being of fundamental interest. We report here on some scanning electron microscope observations we have made of onion skin cells that have been subjected to electron beam bombardment of sufficiently high power density to damage the cell wall. The damage seen is much less than and different from the microcraters formed subsequent to ion bombardment. We speculate that the microcraters may originate from the explosive release of gas generated in the biomaterial by ion bombardment.

Silurian shale origin for light oil, condensate, and gas in Algeria and the Middle East  

SciTech Connect

Two of the largest gas fields in the world, Hasi R'Mel, Algeria and North Dome, Qatar, also contain substantial condensate and light oil reserves. Gas to source rock geochemical correlation is difficult due to the paucity of molecular parameters in the former although stable isotope composition is invaluable. However, by correlating source rocks with light oils and condensates associated with gas production using traditional geochemical parameters such as biomarkers and isotopes, a better understanding of the origin of the gas is achieved. Much of the crude oil in the Ghadames/Illizi Basins of Algeria has long been thought to have been generated from Silurian shales. New light oil discoveries in Saudi Arabia have also been shown to originate in basal euxinic Silurian shales. Key sterane and terpane biomarkers as well as the stable carbon isotopic compositions of the C15+ saturate and aromatic hydrocarbon fractions allow for the typing of Silurian-sourced, thermally mature light oils in Algeria and the Middle East. Even though biomarkers are often absent due to advanced thermal maturity, condensates can be correlated to the light oils using (1) carbon isotopes of the residual heavy hydrocarbon fractions, (2) light hydrocarbon distributions (e.g., C7 composition), and (3) compound specific carbon isotopic composition of the light hydrocarbons. The carbon isotopes of the C2-C4 gas components ran then be compared to the associated condensate and light oil isotopic composition.

The Irradiation Origin of Beryllium Radioisotopes and Other Short-lived Radionuclides  

E-Print Network (OSTI)

Two explanations exist for the short-lived radionuclides (T1 2 ? 5 Ma) present in the solar system when the calcium-aluminum-rich inclusions (CAIs) first formed. They originated either from the ejecta of a supernova or by the in situ irradiation of nebular dust by energetic particles. With a half-life of only 53 days, Beryllium-7 is then the key discriminant, since it can be made only by irradiation. Using the same irradiation model developed earlier by our group, we calculate the yield of 7 Be. Within model uncertainties associated mainly with nuclear cross sections, we obtain agreement with the experimental value. Moreover, if 7 Be and 10 Be have the same origin, the irradiation time must be short (a few to tens of years), and the proton flux must be of order F ? 2 × 10 10 cm ?2 s ?1. The x-wind model provides a natural astrophysical setting that gives the requisite conditions. In the same irradiation environment, 26 Al, 36 Cl and 53 Mn are also generated at the measured levels within model uncertainties, provided that irradiation occurs under conditions reminiscent of solar impulsive events (steep energy spectra and high 3 He abundance). The decoupling of the 26 Al and 10 Be observed in some rare CAIs receives a quantitative explanation when rare 1 Université Paris XI-Centre de Spectrométrie Nucléaire et de Spectrométrie de Masse (CSNSM), Bâtiment

HISTORY OF THE ORIGIN OF THE CHEMICAL ELEMENTS AND THEIR DISCOVERIES.  

SciTech Connect

The origin of the chemical elements show a wide diversity with some of these elements having their origin in antiquity. Still other elements have been synthesized within the past fifty years via nuclear reactions on heavy elements, because these other elements are unstable and radioactive and do not exist in nature. The names of the elements come from many sources including mythological concepts or characters; places, areas or countries; properties of the element or its compounds, such as color, smell or its inability to combine; and the names of scientists. There are also some miscellaneous names as well as some obscure names for particular elements. The claim of discovery of an element has varied over the centuries. Many claims, e.g., the discovery of certain rare earth elements of the lanthanide series, involved the discovery of a mineral ore from which an element was later extracted. The honor of discovery has often been accorded not to the person who first isolated the element but to the person who discovered the original mineral itself, even when the ore was impure and contained many elements. The reason for this is that in the case of these rare earth elements, the ''earth'' now refers to oxides of a metal not to the metal itself. This fact was not realized at the time of their discovery, until the English chemist Humphry Davy showed that earths were compounds of oxygen and metals in 1808. In the early discoveries, the atomic weight of an element and spectral analysis of the element were not available. Later both of these elemental properties would be required before discovery of the element would be accepted. In general, the requirements for discovery claims have tightened through the years and claims that were previously accepted would no longer meet the minimum constraints now imposed. There are cases where the honor of discovery is not given to the first person to actually discover the element but to the first person to claim the discovery in print. If a publication was delayed, the discoverer has often historically been ''scooped'' by another scientist.

On The Origin Of High Energy Correlations in Gamma-ray Bursts  

Science Conference Proceedings (OSTI)

I investigate the origin of the observed correlation between a gamma-ray burst's {nu}F{sub {nu}} spectral peak E{sub pk} and its isotropic equivalent energy E{sub iso} through the use of a population synthesis code to model the prompt gamma-ray emission from GRBs. By using prescriptions for the distribution of prompt spectral parameters as well as the population's luminosity function and co-moving rate density, I generate a simulated population of GRBs and examine how bursts of varying spectral properties and redshift would appear to a gamma-ray detector here on Earth. I find that a strong observed correlation can be produced between the source frame Epk and Eiso for the detected population despite the existence of only a weak and broad correlation in the original simulated population. The energy dependance of a gamma-ray detector's flux-limited detection threshold acts to produce a correlation between the source frame E{sub pk} and E{sub iso} for low luminosity GRBs, producing the left boundary of the observed correlation. Conversely, very luminous GRBs are found at higher redshifts than their low luminosity counterparts due to the standard Malquest bias, causing bursts in the low E{sub pk}, high E{sub iso} regime to go undetected because their E{sub pk} values would be redshifted to energies at which most gamma-ray detectors become less sensitive. I argue that it is this previously unexamined effect which produces the right boundary of the observed correlation. Therefore, the origin of the observed correlation is a complex combination of the instrument's detection threshold, the intrinsic cutoff in the GRB luminosity function, and the broad range of redshifts over which GRBs are detected. Although the GRB model presented here is a very simplified representation of the complex nature of GRBs, these simulations serve to demonstrate how selection effects caused by a combination of instrumental sensitivity and the cosmological nature of an astrophysical population can act to produce an artificially strong correlation between observed properties.

RUSSIAN-ORIGIN HIGHLY ENRICHED URANIUM SPENT NUCLEAR FUEL SHIPMENT FROM BULGARIA  

SciTech Connect

In July 2008, the Global Threat Reduction Initiative and the IRT 2000 research reactor in Sofia, Bulgaria, operated by the Institute for Nuclear Research and Nuclear Energy (INRNE), safely shipped 6.4 kilograms of Russian origin highly enriched uranium (HEU) spent nuclear fuel (SNF) to the Russian Federation. The shipment, which resulted in the removal of all HEU from Bulgaria, was conducted by truck, barge, and rail modes of transport across two transit countries before reaching the final destination at the Production Association Mayak facility in Chelyabinsk, Russia. This paper describes the work, equipment, organizations, and approvals that were required to complete the spent fuel shipment and provides lessons learned that might assist other research reactor operators with their own spent nuclear fuel shipments.

Origin of radiation tolerance in 3C-SiC with nanolayered planar defects  

SciTech Connect

We have recently found that the radiation tolerance of SiC is highly enhanced by introducing nanolayers of stacking faults and twins [Y. Zhang et al., Phys. Chem. Chem. Phys. 14, 13429 (2012)]. To reveal the origin of this radiation resistance, we used in situ transmission electron microscopy to examine structural changes induced by electron beam irradiation in 3C-SiC containing nanolayers of (111) planar defects. We found that preferential amorphization, when it does occur, takes place at grain boundaries and at 111 and 111 planar defects. Radiationinduced point defects, such as interstitials and vacancies, migrate two-dimensionally between the (111) planar defects, which probably enhances the damage recovery.

An original image slicer designed for Integral Field Spectroscopy with NIRSpec/JSWT  

E-Print Network (OSTI)

Integral Field Spectroscopy (IFS) provides a spectrum simultaneously for each spatial sample of an extended, two-dimensional field. It consists of an Integral Field Unit (IFU) which slices and re-arranges the initial field along the entrance slit of a spectrograph. This article presents an original design of IFU based on the advanced image slicer concept. To reduce optical aberrations, pupil and slit mirrors are disposed in a fan-shaped configuration that means that angles between incident and reflected beams on each elements are minimized. The fan-shaped image slicer improves image quality in terms of wavefront error by a factor 2 comparing with classical image slicer and, furthermore it guaranties a negligible level of differential aberration in the field. As an exemple, we are presenting the design LAM used for its proposal at the NIRSPEC/IFU invitation of tender.

Gauge origin of M parity and the {mu} term in supersymmetry  

SciTech Connect

In this article, we present a simple theoretical framework where the origin of the {mu} term and the matter-parity-violating interactions of the minimal supersymmetric standard model can be understood from the spontaneous breaking of new Abelian gauge symmetries. In this context, the masses of the Z{sup '} gauge bosons, the M-parity-violating scale and the {mu} term are determined by the supersymmetry breaking scale. The full spectrum of the theory is discussed in detail. We investigate the predictions for the Higgs masses in detail showing that it is possible to satisfy the LEP2 bounds even with sub-TeV squark masses. The model predicts the existence of light colored fields, lepton- and baryon-number violation, and new neutral gauge bosons at the Large Hadron Collider.

Origin of gaseous hydrocarbons from Upper Cretaceous and Tertiary strata in the Piceance basin, western Colorado  

E-Print Network (OSTI)

Natural gas samples were collected for geochemical analyses from Upper Cretaceous and Tertiary strata of the Piceance basin in western Colorado to: 1) determine the origin of gases (i.e., microbial versus thermogenic), 2) determine the thermogenic source rock(s) for the gas-rich Williams Fork Formation, and 3) assess the nature of gas migration. Mud logging gases were sampled approximately every 60 m between 350 and 2800 m and analyzed for "C compositions and CI/C,-3 ratios. Samples collected from low gas content intervals above 1950 m define two parallel trends of increasing "Cc, content with depth. Data from the first trend are based on eighteen analyses and range from-69.9 to-38.3%o (R 2 = 0.92). These data suggest a microbial and mixed microbial/thermogenic origin for methane. Only one sample from above 1950 m contained sufficient amounts of C2for isotopic analysis (813 CC2 =-27.0%o at 1718 m). Data from the second trend are based on seven analyses and are offset by approximately +20%o compared with the primary trend at comparable depths. These data range from-65.0 to-38.5%0 (R' = 0.84). 813c ci and C,/CI-3data from both trends are similar when viewed on a crossplot, thus suggesting that large-scale, vertical gas migration has occurred. Migration was probably aided by fractures that formed during maximum burial and peak gas generation. Except for one sample collected at 1718 m, "CC2compositions above 1950 m were not determined due to insufficient sample sizes. Below 1950 m, gas contents abruptly increase and approach 10-4' gas units. These gases have "C compositions indicative of thermogenic origin. Gases between 1950 and 2450 m have relatively uniform geochemistries (8"Cc, =-39.9 0?.3%ol 613C C2 =-27.4 I?.i%ol CI/Cl-3 = 0-91 0?.03), and are chemically distinct and therefore Renetically different from gases between 2450 and 2791 M (513C ci =-37.9 +-O.2%og 813C C2 =-26.4 0?.5%09 CI/Cl-3 = 0.88 0?.01). Gases of the latter group were probably derived from coalbeds that comprise the Cameo Group, as abundant coals are found between 2450 and 2630 m. Only three thin coalbeds occur within the Coal Ridge Group between 1950 and 2450 m, so gases from this interval were probably derived from interbedded shales. Core and cuttings samples were also collected and sealed in cans from several intervals for geochemical analyses. Canned methanes at or above 858 m are "C-enriched by 13 to 33%o compared with logging methanes at equivalent intervals. Below 1934 m, however, 813C ci values for core and cuttings are comparable to logging gas values. This observation suggests that 813 Cc, discrepancies above 858 m are related to low gas contents in the core and cutting samples. Therefore, geochemical data from core and cuttings were not used to assess migration or to interpret gas origin.

What is the origin of the mass of the Higgs boson?

The purpose of this paper is to present a unified description of mass generation mechanisms that have been investigated so far and that are called the Mach and Higgs proposals. In our mechanism, gravity acts merely as a catalyst and the final expression of the mass depends neither on the intensity nor on the particular properties of the gravitational field. We shall see that these two strategies to provide mass for all bodies that operate independently and competitively can be combined into a single unified theoretical framework. As a consequence of this new formulation we are able to present an answer to the question: what is the origin of the mass of the Higgs boson?

A method of correlating a core sample with its original position in a borehole. The borehole is logged to determine the bulk density of the formation surrounding the borehole. The core sample is scanned with a computerized axial tomographic scanner (CAT) to determine the attenuation coefficients at a plurality of points in a plurality of cross sections along the core sample. The bulk density log is then compared with the attenuation coefficients to determine the position to which the core sample correlates in the borehole. Alternatively, the borehole can be logged to determine the photoelectric absorption of the formation surrounding the borehole, and this log can be compared with data derived from scanning the core sample with a CAT at two different energy levels.

The origin of hydrothermal and other gases in the Kenya Rift Valley  

SciTech Connect

The Kenya Rift Valley (KRV) is part of a major continental rift system from which much outgassing is presently occurring. Previous research on gases in the KRV has tended to concentrate on their geothermal implications; the present paper is an attempt to broaden the interpretation by consideration of new data including helium and carbon isotope analyses from a wide cross-section of sites. In order to do this, gases have been divided into categories dependent on origin. N{sub 2} and noble gases are for the most part atmospherically derived, although their relative concentrations may be altered from ASW ratios by various physical processes. Reduced carbon (CH{sub 4} and homologues) appears to be exclusively derived from the shallow crust, with thermogenic {delta}{sup 13}C values averaging -25{per_thousand} PDB for CH{sub 4}. H{sub 2} is likely also to be crustally formed. CO{sub 2}, generally a dominant constituent, has a narrow {delta}{sup 13}C range averaging -3.7{per_thousand} PDB, and is likely to be derived with little modification from the upper mantle. Consideration of the ratio C/{sup 3}He supports this view in most cases. Sulphur probably also originates there. Ratios of {sup 3}He/{sup 4}He reach a MORB-like maximum of 8.0 R/R{sub A} and provide the best indication of an upper mantle source of gases beneath the KRV. A correlation between {sup 3}He/{sup 4}He and the hydrocarbon parameter log (C{sub 1}/{Sigma}C{sub 2-4}) appears to be primarily temperature related. The highest {sup 3}He/{sup 4}He ratios in spring waters are associated with basalts, perhaps because of the leaching of basalt glasses. There may be a structural control on {sup 3}He/{sup 4}He ratios in the KRV as a whole.

BCL2 major breakpoint region (mbr) may specify an origin of replication  

Science Conference Proceedings (OSTI)

We have described a minisatellite consensus signal, GC[A/T]GG[A/T]GG, which resembles the prokaryotic activator of recombination, {chi}. The consensus appears frequently at the breakpoints of oncogene translocations, especially those in which the V(D)J recombinase has been implicated. We have investigated this relationship by examining the breakpoint positions and DNA sequence of many mbr translations from human follicular lymphomas. Breakpoints occur in three, evenly-spaced clusters 14-18 bp wide and 50 bp apart; the first cluster begins at the first base 3{prime} to the {chi} signal. At the end of cluster 3, translocations abruptly decline in frequency. We now report that this region is characterized by multiple binding sites for both single- and double-strand DNA binding proteins. Furthermore, the binding sites immediately flank clusters 1 and 3, thus defining the region at risk for translocation. The two single-strand binding proteins, one each for the sense and anti-sense strand of BCL2, bind the {chi} signal that marks the onset of translocation. The second binding site, which begins at the 3{prime} flank of cluster 3, extends a further 80 bp downstream and is absolutely required for the interaction of the mbr with factor(s) which can denature the target DNA in a cell-specific fashion. This process requires energy, as complex formation is inhibited by ATP{gamma}S. One of the two ssDNA binding proteins and, possibly, the helicase activity are expressed in a cell-cycle-dependent fashion. Finally, helical stability studies of the helicase binding region yield a profile comparable to those previously defined for several viral, yeast, and bacterial origins of replication. These studies indicate that BCL2 translocation may reflect (1) a requirement for removing a replication origin from the gene to promote lymphomagenesis and/or (2) the recombinogenic nature of such structures.

Empirical evidence for a celestial origin of the climate oscillations and its implications  

E-Print Network (OSTI)

We investigate whether or not the decadal and multi-decadal climate oscillations have an astronomical origin. Several global surface temperature records since 1850 and records deduced from the orbits of the planets present very similar power spectra. Eleven frequencies with period between 5 and 100 years closely correspond in the two records. Among them, large climate oscillations with peak-to-trough amplitude of about 0.1 $^oC$ and 0.25 $^oC$, and periods of about 20 and 60 years, respectively, are synchronized to the orbital periods of Jupiter and Saturn. Schwabe and Hale solar cycles are also visible in the temperature records. A 9.1-year cycle is synchronized to the Moon's orbital cycles. A phenomenological model based on these astronomical cycles can be used to well reconstruct the temperature oscillations since 1850 and to make partial forecasts for the 21$^{st}$ century. It is found that at least 60\\% of the global warming observed since 1970 has been induced by the combined effect of the above natural...

A 2-Dimensional Cellular Automaton for Agents Moving from Origins to Destinations  

E-Print Network (OSTI)

We develop a two-dimensional cellular automaton (CA) as a simple model for agents moving from origins to destinations. Each agent moves towards an empty neighbor site corresponding to the minimal distance to its destination. The stochasticity or noise ($p$) is introduced in the model dynamics, through the uncertainty in estimating the distance from the destination. The friction parameter $"\\mu"$ is also introduced to control the probability that the movement of all agents involved to the same site (conflict) is denied at one time step. This model displays two states; namely the freely moving and the jamming state. If $\\mu$ is large and $p$ is low, the system is in the jamming state even if the density is low. However, if $\\mu$ is large and $p$ is high, a freely moving state takes place whenever the density is low. The cluster size and the travel time distributions in the two states are studied in detail. We find that only very small clusters are present in the freely moving state while the jamming state displ...

The Origins of the SPAR-H Method's Performance Shaping Factor Multipliers  

Science Conference Proceedings (OSTI)

The Standardized Plant Analysis Risk-Human Reliability Analysis (SPAR-H) method has proved to be a reliable, easy-to-use method for human reliability analysis. Calculation of human error probability (HEP) rates is especially straightforward, starting with pre-defined nominal error rates for cognitive vs. action oriented tasks, and incorporating performance shaping factor (PSF) multipliers upon those nominal error rates. SPAR-H uses eight PSFs with multipliers typically corresponding to nominal, degraded, and severely degraded human performance for individual PSFs. Additionally, some PSFs feature multipliers to reflect enhanced performance. Although SPAR-H enjoys widespread use among industry and regulators, current source documents on SPAR-H such as NUREG/CR-6883 do not provide a clear account of the origin of these multipliers. The present paper redresses this shortcoming and documents the historic development of the SPAR-H PSF multipliers, from the initial use of nominal error rates, to the selection of the eight PSFs, to the mapping of multipliers to available data sources such as a Technique for Human Error Rate Prediction (THERP). Where error rates were not readily derived from THERP and other sources, expert judgment was used to extrapolate appropriate values. In documenting key background information on the multipliers, this paper provides a much needed cross-reference for human reliability practitioners and researchers of SPAR-H to validate analyses and research findings.

Evaluation of Catalysts from Different Origin for Vapor Phase Upgrading in Biomass Pyrolysis  

SciTech Connect

Liquid fuels and chemicals from biomass resources arouse much interests in research and development. Fast pyrolysis of biomass has the potential to effectively change solid biomass materials into liquid products. However, bio-oil from traditional pyrolysis processes is difficult to apply in industry, because of its complicated composition, high oxygen content, low stability, etc. Upgrading or refining of the bio-oil should be performed for industrial application of biomass pyrolysis. Often, the process would be done in a separate reactor downstream of the pyrolysis process. In this paper, a laboratory scale micro test facility was constructed, wherein the pyrolysis of pine and catalytic upgrading of the resulting vapors were closely coupled in one reactor. The composition of vapor effluent was monitored with a molecular beam mass spectrometer (MBMS) for the online evaluation of the catalyst performance. Catalysts from different origin were tested and compared for the effectiveness of pyrolysis vapor upgrading, namely commercial zeolites, Ni based steam reforming catalyst, CaO, MgO, and several laboratory-made catalysts. The reaction temperature for catalytic upgrading varied between 400 and 600 centigrade, and the gaseous residence time ranged from 0.1 second to above 2 second, to simulate the conditions in industrial application. It is revealed that some catalysts are active in transform most of primary biomass pyrolysis vapors into hydrocarbons, resulting in nonoxygenated products, which is beneficial for downstream utilization. Others are not as effective, results in minor improvement compared with blank test results.

Microcanonical Thermostatistics as Foundation of Thermodynamics. The microscopic origin of condensation and phase separations  

E-Print Network (OSTI)

Conventional thermo-statistics address infinite homogeneous systems within the canonical ensemble. However, some 150 years ago the original motivation of thermodynamics was the description of steam engines, i.e. boiling water. Its essential physics is the separation of the gas phase from the liquid. Of course, boiling water is inhomogeneous and as such cannot be treated by canonical thermo-statistics. Then it is not astonishing, that a phase transition of first order is signaled canonically by a Yang-Lee singularity. Thus it is only treated correctly by microcanonical Boltzmann-Planck statistics. This is elaborated in the present article. It turns out that the Boltzmann-Planck statistics is much richer and gives fundamental insight into statistical mechanics and especially into entropy. This can even be done to some extend rigorously and analytically. The microcanonical entropy has a very simple physical meaning: It measures the microscopic uncertainty that we have about the system, i.e. the number of points in $6N$-dim phase, which are consistent with our information about the system. It can rigorously be split into an ideal-gas part and a configuration part which contains all the physics and especially is responsible for all phase transitions. The deep and essential difference between ``extensive'' and ``intensive'' control parameters, i.e. microcanonical and canonical statistics, is exemplified by rotating, self-gravitating systems.

The deep and essential difference between ``extensive'' and ``intensive'' control parameters, i.e. microcanonical and canonical statistics, is exemplified by rotating, self-gravitating systems. In this paper the necessary appearance of a convex entropy $S(E)$ and the negative heat capacity at phase separation in small as well macroscopic systems independently of the range of the force is pointed out. The appearance of a critical end-point for the liquid-gas transition in the $p-E$ or $V-E$ phase diagram can be easily explained as well the non-existence of a critical end-point of the solid-liquid transition.

Nuclear astrophysics: the unfinished quest for the origin of the elements  

E-Print Network (OSTI)

Half a century has passed since the foundation of nuclear astrophysics. Since then, this discipline has reached its maturity. Today, nuclear astrophysics constitutes a multidisciplinary crucible of knowledge that combines the achievements in theoretical astrophysics, observational astronomy, cosmochemistry and nuclear physics. New tools and developments have revolutionized our understanding of the origin of the elements: supercomputers have provided astrophysicists with the required computational capabilities to study the evolution of stars in a multidimensional framework; the emergence of high-energy astrophysics with space-borne observatories has opened new windows to observe the Universe, from a novel panchromatic perspective; cosmochemists have isolated tiny pieces of stardust embedded in primitive meteorites, giving clues on the processes operating in stars as well as on the way matter condenses to form solids; and nuclear physicists have measured reactions near stellar energies, through the combined efforts using stable and radioactive ion beam facilities. This review provides comprehensive insight into the nuclear history of the Universe and related topics: starting from the Big Bang, when the ashes from the primordial explosion were transformed to hydrogen, helium, and few trace elements, to the rich variety of nucleosynthesis mechanisms and sites in the Universe. Particular attention is paid to the hydrostatic processes governing the evolution of low-mass stars, red giants and asymptotic giant-branch stars, as well as to the explosive nucleosynthesis occurring in core-collapse and thermonuclear supernovae, gamma-ray bursts, classical novae, X-ray bursts, superbursts, and stellar mergers.

Understanding the Origins of Time-Dependent Inhibition by Polypeptide Deformylase Inhibitors  

SciTech Connect

The continual bacterial adaptation to antibiotics creates an ongoing medical need for the development of novel therapeutics. Polypeptide deformylase (PDF) is a highly conserved bacterial enzyme, which is essential for viability. It has previously been shown that PDF inhibitors represent a promising new area for the development of antimicrobial agents, and that many of the best PDF inhibitors demonstrate slow, time-dependent binding. To improve our understanding of the mechanistic origin of this time-dependent inhibition, we examined in detail the kinetics of PDF catalysis and inhibition by several different PDF inhibitors. Varying pH and solvent isotope led to clear changes in time-dependent inhibition parameters, as did inclusion of NaCl, which binds to the active site metal of PDF. Quantitative analysis of these results demonstrated that the observed time dependence arises from slow binding of the inhibitors to the active site metal. However, we also found several metal binding inhibitors that exhibited rapid, non-time-dependent onset of inhibition. By a combination of structural and chemical modification studies, we show that metal binding is only slow when the rest of the inhibitor makes optimal hydrogen bonds within the subsites of PDF. Both of these interactions between the inhibitor and enzyme were found to be necessary to observe time-dependent inhibition, as elimination of either leads to its loss.

The Origin of Surface-Enhanced Raman Scattering of 4,4' -Biphenyldicarboxylate on Silver Substrates  

Science Conference Proceedings (OSTI)

We combine scanning electron microscopy, atomic force microscopy, surface-enhanced Raman scattering (SERS), and tools of computational chemistry to investigate the origin of Raman scattering of 4,4’-biphenyldicarboxylic acid adsorbed as 4,4’-biphenyldicarboxylate on two different silver substrates. The first consists of a 100 nm deep cylindrical aperture embedded in an array of cylindrical nano-holes featuring an average diameter of 350 nm and a periodicity of 700 nm. The second is a nano-junction formed by a 100 nm silver nano-particle coated with the adsorbate and a flat silver surface. We find that the underlying background signal in the SERS spectra collected from the former strongly resemble the SERS spectra of the nano-sphere-featuring substrate, engineered to operate in the charge transfer plasmon limit. Our analysis of a series of SERS spectra consecutively collected from one nano-cylinder suggests that the optical response of a single molecule can be extracted, its brightest Raman active mode enhanced by a factor of 7.4 x 106.

ON THE ORIGIN OF > 10 GeV PHOTONS IN GAMMA-RAY BURST AFTERGLOWS  

Science Conference Proceedings (OSTI)

Fermi/LAT has detected long-lasting high-energy photons (>100 MeV) from gamma-ray bursts (GRBs), with the highest energy photons reaching about 100 GeV. One proposed scenario is that they are produced by high-energy electrons accelerated in GRB forward shocks via synchrotron radiation. We study the maximum synchrotron photon energy in this scenario, considering the properties of the microturbulence magnetic fields behind the shock, as revealed by recent particle-in-cell simulations and theoretical analyses of relativistic collisionless shocks. Due to the small-scale nature of the microturbulent magnetic field, the Bohm acceleration approximation, in which the scattering mean free path is equal to the particle Larmor radius, breaks down at such high energies. This effect leads to a typical maximum synchrotron photon of a few GeV at 100 s after the burst and this maximum synchrotron photon energy decreases quickly with time. We show that the fast decrease of the maximum synchrotron photon energy leads to a fast decay of the synchrotron flux. The 10-100 GeV photons detected after the prompt phase cannot be produced by the synchrotron mechanism. They could originate from the synchrotron self-Compton emission of the early afterglow if the circumburst density is sufficiently large, or from the external inverse Compton process in the presence of central X-ray emission, such as X-ray flares and prompt high-latitude X-ray emission.

Heat transfer in sunspot penumbrae. Origin of dark-cored penumbral filaments  

E-Print Network (OSTI)

Context: Observations at 0.1" have revealed the existence of dark cores in the bright filaments of sunspot penumbrae. Expectations are high that such dark-cored filaments are the basic building blocks of the penumbra, but their nature remains unknown. Aims: We investigate the origin of dark cores in penumbral filaments and the surplus brightness of the penumbra. To that end we use an uncombed penumbral model. Methods: The 2D stationary heat transfer equation is solved in a stratified atmosphere consisting of nearly horizontal magnetic flux tubes embedded in a stronger and more vertical field. The tubes carry an Evershed flow of hot plasma. Results: This model produces bright filaments with dark cores as a consequence of the higher density of the plasma inside the tubes, which shifts the surface of optical depth unity toward higher (cooler) layers. Our calculations suggest that the surplus brightness of the penumbra is a natural consequence of the Evershed flow, and that magnetic flux tubes about 250 km in diameter can explain the morphology of sunspot penumbrae.

Geometric Origin of Physical Constants in a Kaluza-Klein Tetrad Model  

E-Print Network (OSTI)

An important feature of Kaluza-Klein theories is their ability to relate fundamental physical constants to the radii of higher dimensions. In previous Kaluza-Klein theory, which unifies the electromagnetic field with gravity as dimensionless components of a Kaluza-Klein metric, i) all fields have the same physical dimensions, ii) the Lagrangian has no explicit dependence on any physical constants except mass, and hence iii) all physical constants in the field equations except for mass originate from geometry. While it seems natural in Kaluza-Klein theory to add fermion fields by defining higher dimensional bispinor fields on the Kaluza-Klein manifold, these Kaluza-Klein theories do not satisfy conditions (i), (ii), and (iii). In this paper, we show how conditions (i), (ii), and (iii) can be satisfied by including bispinor fields in a tetrad formulation of the Kaluza-Klein model, as well as in an equivalent teleparallel model. This demonstrates an unexpected feature of Dirac's bispinor equation, since conditions (i), (ii), (iii) imply a special relation among the terms in the Kaluza-Klein or teleparallel Lagrangian that would not be satisfied in general.

Two Trends of Composition Variation of Zircons and Their Significance in Origin Discrimination  

E-Print Network (OSTI)

Zircon can crystallize in a wide range of physical and chemical conditions. At the same time, it has very high stability and durability. Therefore zircon can grow and survive in a variety of geological processes. In addition, the diffusivity of chemical compositions in its crystal is very low. Consequently, we can trace back the evolution history of the planetary materials containing zircon by zircon U-Th-Pb geochronology and geochemistry studies. However, this depends on our ability to decipher its genesis,namely magmatic or metamorphic origins. In this paper, we have found that there are obvious differences between magmatic and metamorphic zircons in their chemical composition zonations. The magmatic zircons exhibit composition zonation of increasing HfO2, and (UO2 + ThO2) content and decreasing ZrO2/HfO2 ratio and ZrO2 content from inner to outer parts within each growth zone or from core to rim of a crysta1. The metamorphic zircons exhibit compositional variation trend opposite to that of magmatic (igneou...

Origin of stress in radio frequency magnetron sputtered zinc oxide thin films  

SciTech Connect

Highly c-axis oriented ZnO thin films have been deposited on silicon substrates by planar rf magnetron sputtering under varying pressure (10-50 mTorr) and oxygen percentage (50-100%) in the reactive gas (Ar + O{sub 2}) mixture. The as-grown films were found to be stressed over a wide range from -1 x 10{sup 11} to -2 x 10{sup 8} dyne/cm{sup 2} that in turn depends strongly on the processing conditions, and the film becomes stress free at a unique combination of sputtering pressure and reactive gas composition. Raman spectroscopy and photoluminescence (PL) analyses identified the origin of stress as lattice distortion due to defects introduced in the ZnO thin film. FTIR study reveals that Zn-O bond becomes stronger with the increase in oxygen fraction in the reactive gas mixture. The lattice distortion or stress depends on the type of defects introduced during deposition. PL spectra show the formation of a shoulder in band emission with an increase in the processing pressure and are related to the presence of stress. The ratio of band emission to defect emission decreases with the increase in oxygen percentage from 50 to 100%. The studies show a correlation of stress with the structural, vibrational, and photoluminescence properties of the ZnO thin film. The systematic study of the stress will help in the fabrication of efficient devices based on ZnO film.

On the Origin of the Colour-Magnitude Relation in the Virgo Cluster  

E-Print Network (OSTI)

We explore the origin of the colour-magnitude relation (CMR) of early type galaxies in the Virgo cluster using spectra of very high S/N ratio for six elliptical galaxies selected along the CMR. The data are analysed using a new evolutionary stellar population synthesis model to generate galaxy spectra at the resolution given by their velocity dispersions. In particular we use a new age indicator that is virtually free of the effects of metallicity. We find that the luminosity weighted mean ages of Virgo ellipticals are greater than ~8 Gyr, and show no clear trend with galaxy luminosity. We also find a positive correlation of metallicity with luminosity, colour and velocity dispersion. We conclude that the CMR is driven primarily by a luminosity-metallicity correlation. However, not all elements increase equally with the total metallicity and we speculate that the CMR may be driven by both a total metallicity increase and by a systematic departure from solar abundance ratios of some elements along the CMR. A full understanding of the role played by the total metallicity, abundance ratios and age in generating the CMR requires the analysis of spectra of very high quality, such as those reported here, for a larger number of galaxies in Virgo and other clusters.

The dog originated south of Yangtse river less than 16,000 years ago, from numerous wolves  

SciTech Connect

We here present a detailed picture of the origins of the dog, giving strong and precise evidence for 'where and when', and thereby also a first tentative picture of 'how, why and by whom' the wolf was domesticated. Previous studies of mitochondrial DNA (mtDNA) have failed to definitely establish the time and place of origin because of lack in phylogenetic resolution for the so far studied 582 bp region, and inadequate sampling across the world. We therefore analysed 169 mtDNA genomes, selected from partial sequences (582 bp) from 1,576 dogs worldwide. This shows that dogs universally share a common gene pool, but the three earlier identified universally occurring phylogenetic clades ofhigh age consist often much younger subclades, which originated 5,000-16,000 ya from at least 48 wolf founders. The full range of genetic diversity, all 10 subclades, is found only in south-eastern Asia south of Yangtze River, and the diversity decreases gradually across Eurasia down to only four sub clades in Europe. This establishes that the dog has a single origin in time and space from a large number ofwolves, less than 16,000 ya, probably in China south of Y angtzeRiver. The place and time coincide with the origin of rice agriculture, suggesting an origin among sedentary hunter-gatherers or early rice farmers. The numerous founders indicate that wolf taming was an important cultural trait, and it is noticeable that in this region dogs are since ancient times used as food, offering a possible reason for the wolf domestication.

The origin of organic pollutants from the combustion of alternative fuels: Phase IV report  

DOE Green Energy (OSTI)

As part of the US-DOE`s on-going interest in the use of alternative automotive fuels, the University of Dayton Research Institute has been conducting research on pollutant emissions resulting from the combustion of candidate fuels. This research, under the direction and sponsorship of the NREL, has been concerned primarily with the combustion of compressed natural gas, liquefied petroleum gas (LPG), methanol, and ethanol. In the first 24 months of this program, studies of the oxygen rich, stoichiometric, and fuel-rich thermal degradation of these fuels in the temperature range of 300 to 1100{degrees}C at atmospheric pressure and for reaction times of 1.0 and 2.0 s were completed. Trace organic products were identified and quantified for each fuel as a function of temperature. The results of these studies agreed well with the results of tail-pipe emission studies in that the types and quantity of emissions measured in both the laboratory and engine tests were shown to be very similar under certain operating conditions. However, some chemicals were observed in the laboratory studies that were not observed in the engine studies and vice versa. This result is important in that it has implications concerning the origin of these emissions. Experiments concerning the NO perturbed oxidation of methanol, M85, ethanol, and E85 indicated the presence of complex oxidation chemistry. At mild temperatures, NO addition resulted in enhanced fuel conversion. At elevated temperatures, an inhibitory effect was observed through increased yields of both partial oxidation and pyrolysis-type reaction products. Comparison of flow reactor product distributions with engine test results generally indicated improved comparisons when NO was added to the fuel. Analysis of secondary components of alcohol fuels resulted in some unexpected observations. Several previously unidentified species were observed in these experiments which may impact atmospheric reactivity assessments of these fuels.

We are proposing a new way of describing families of quarks and leptons, using the approach unifying all the internal degrees of freedom, proposed by one of us. Spinors, living in d(=1+13)-dimensional space, carry in this approach only the spin and interact with only the gravity through vielbeins and two kinds of the spin connection fields - the gauge fields of the Poincare group and the second kind of the Clifford algebra objects. All the quarks and the leptons of one family appear in one Weyl representation of a chosen handedness of the Lorentz group, if analyzed with respect to the Standard model gauge groups: the right handed (with respect to SO(1,3)) weak chargeless quarks and leptons and the left handed weak charged quark and leptons. A part of the starting Lagrange density of a Weyl spinor in d=1+13 transforms right handed quarks and leptons into left handed quarks and leptons manifesting as the Yukawa couplings of the Standard model. The second kind of Clifford algebra objects generates families and contributes to diagonal and off diagonal Yukawa couplings. The approach predicts an even number of families, treating leptons and quarks equivalently. In this paper we investigate within this approach the appearance of the Yukawa couplings within one family of quarks and leptons as well as among the families (without assuming any Higgs fields). We present the mass matrices for four families and investigate whether our way of generating families might explain the origin of families of quarks and leptons as well as their observed properties - the masses and the mixing matrices. Numerical results are presented in the paper following this one.

Microscopic quantum structure of black hole and vacuum versus quantum statistical origin of gravity  

E-Print Network (OSTI)

The Planckon densely piled model of vacuum is proposed. Based on it, the microscopic quantum structure of Schwarzschild black hole and quantum statistical origin of its gravity are studied. It is shown that thermodynamic temperature equilibrium and mechanical acceleration balance make the space-time of the black hole horizon singular and Casimir effect works inside the horizon. This effect makes the inside vacuum have less zero fluctuation energy than the outside vacuum, and a temperature difference as well as gravity as thermal pressure are created. A dual relation between inside and outside regions of the black hole is found. By the dual relation, an attractor behaviour of the horizon surface is unveiled. Outside horizon, there exist thermodynamic non-equilibrium and mechanical non-balance which lead to outward centrifugal energy flow and inward gravitation energy flow, their compensation establishes local equilibrium. The lost vacuum energy in negative gravitation potential regions has been removed to the black hole surface to form a spherical Planckon shell with the thickness of Planckon diameter. All the particles absorbed by the black hole have fallen down to the horizon and converted into spin 1/2 radiation quanta made of standing waves on the horizon sphere with the mean energy related to Hawking-Unruh temperature, thermodynamic equilibrium and mechanical balance keep them stable and be tightly bound in the horizon. The gravitation mass 2M and physical mass $M$ of the black hole are calculated. The entropy of the black hole, calculated from the microscopic state number of the many-body system of radiation fermion quanta, is well consistent with Hawking. A radical modification of the temperature law of the black hole is made. The accelerating expansion of the universe yields the expansion cosmon and its energy density agrees with dark energy density.

Waters of Hot Springs National Park, Arkansas: their nature and origin  

DOE Green Energy (OSTI)

The 47 hot springs of Hot Springs National Park, Arkansas, issue from the plunging crestline of a large overturned anticline, along the southern margin of the Ouachita anticlinorium, in the Zigzag Mountains. The combined flow of the hot springs ranges from 750,000 to 950,000 gallons per day (3.29 x 10/sup -2/ to 4.16 x 10/sup -2/ cubic meters per second). The radioactivity and chemical composition of the hot-water springs are similar to that of the cold-water springs and wells in the area. The tritium and carbon-14 analyses of the water indicate that the water is a mixture of a very small amount of water less than 20 years old and a preponderance of water about 4400 years old. The presence of radium and radon in the hot-springs waters has been established by analyses. Mathematical models were employed to test various conceptual models of the hot-springs flow system. The geochemical data, flow measurements, and geologic structure of the region support the concept that virtually all the hot-springs water is of local, meteoric origin. Recharge to the hot-springs artesian-flow system is by infiltration of rainfall in the outcrop areas of the Bigfork Chert and the Arkansas Novaculite. The water moves slowly to depth where it is heated by contact with rocks of high temperature. Highly permeable zones, related to jointing or faulting, collect the heated water in the aquifer and provide avenues for the water to travel rapidly to the surface.

Two Trends of Composition Variation of Zircons and Their Significance in Origin Discrimination  

E-Print Network (OSTI)

Zircons can crystallize in a wide range of physical and chemical conditions. At the same time, they have high stability and durability. Therefore zircons can grow and survive in a variety of geological processes. In addition, the diffusivity of chemical compositions in their crystals is very low. Consequently,we can trace back the evolution history of the planetary materials containing zircon by zircon U-Th-Pb geochronology and geochemistry studies. However, this depends on our ability to decipher its genesis,namely magmatic or metamorphic origins. In this paper, we have found that there are obvious differences between magmatic and metamorphic zircons in their chemical composition zonations. The magmatic zircons exhibit composition zonation of increasing HfO2, and (UO2 + ThO2) content and decreasing ZrO2/HfO2 ratio and ZrO2 content from inner to outer parts within each growth zone or from core to rim of a crysta1. The metamorphic zircons exhibit compositional variation trend opposite to that of magmatic (igneous) zircons,tending to decrease in HfO2, (UO2+ ThO2)and increase in ZrO2/HfO2 ratio and ZrO2 from core to rim of a crystal. These chemical composition variation trends are thought to be controlled by the crystal chemical features of ions themselves and the evolution trends of magmatism and metamorphism respectively, and can be used to identify the genesis of zircons. Their morphological features are also discussed.

Identification of pore type and origin in a Lower Cretaceous carbonate reservoir using NMR T2 relaxation times  

E-Print Network (OSTI)

Determining the distribution of porosity and permeability is one of the main challenges in carbonate petroleum reservoir characterization and requires a thorough understanding of pore type and origin, as well as their spatial distributions. Conventional studies of carbonate reservoirs require interpretation and analysis of cores to understand porosity. This study investigates the use of NMR logs in the determination of pore type and origin. This study is based on the analysis of both thin section petrographic and NMR data from a single well that cored the Lower Cretaceous (Aptian) shelf carbonates belonging to the Shuaiba Formation of the Middle East. Photographs of thin sections were used to determine pore type and origin according to Ahr's genetic classification of carbonate porosity. Descriptive statistics and modeling were used to analyze the NMR T2relaxation time distributions. Descriptive statistical analyses included estimating arithmetic average, standard deviation, skewness, median, mode and 90th percentile. T2modeling was performed by fitting multiple log-normal distributions to the measured T2distribution. Data from thin section petrography and from NMR measurements were then compared using conditional probabilities. As expected, thin section analysis revealed the predominance of mud-supported fabrics and micropores between matrix grains Vugs and dissolved rudistid fragments account for most of the macro porosity. Descriptive statistics showed that the mode and th percentile of the T2distribution had the greatest power to discriminate pores by origin. The first principal component (PC1) of the mode-90th percentile system was then used to compute the probabilities of having each pore origin, knowing that PC1 belongs to a given interval. Results were good, with each origin being predictable within a certain range of PC1. Decomposition of the T2distributions was performed using up to 3 log-normal component distributions. Samples of different pore origin behaved distinctively. Depositional porosity showed no increase in fit quality with increasing number of distributions whereas facies selective and diagenetic porosity did, with diagenetic porosity showing the greatest increase.

Economic impact of country-of-origin labeling in the U.S. beef industry  

E-Print Network (OSTI)

Concerns over the total costs assessed to the beef industry from the implementation of mandatory country-of-origin labeling (COOL) regulations warranted an investigation into the estimation and distribution of marketing and marginal costs of production for retail chain stores and distributors, meat packers and processors, cattle feedlots, cattle backgrounding yards and cow-calf producers. Furthermore, it is thought the implementation of COOL will impose severe market and social welfare effects on the participants in the beef industry. This research focused on two main objectives. The first objective is to provide a full beef industry cost assessment for implementing COOL regulations based on the preliminary guidelines for COOL as published by the United States Department of Agriculture in the proposed rule in October of 2003. Financial and production data was collected and used from U.S. retail chain stores and distributors, meat packers and processors, cattle feedlots, and cattle backgrounding yards and stockers. The second objective was to use the weighted average cost estimates calculated from the data to determine the magnitude of increases in the demand for retail beef, wholesale beef, fed cattle, and feeder cattle needed to negate the increase in costs of implementing mandatory COOL regulations. An equilibrium displacement model was used to demonstrate the supply and demand functions and relationships for retail beef, wholesale beef, fed cattle, and feeder cattle. Estimated elasticities for retail beef, wholesale beef, fed cattle and feeder cattle were used to calculate the relative changes in price and quantity in response to the COOL-induced supply and demand shifts. The quantity intercepts from the estimation of the linear parameters can be used to calculate the increases in consumer demand needed to negate the increases in costs estimated from the survey results for the retail, wholesale, fed cattle, and feeder cattle sectors of the beef industry. A significant cost burden to the beef industry was shown by the weighted average estimates calculated from the research. Retail chain stores and distributors, meat packers and processors, cattle feedlots and cattle stockers are expected to see an increase in marketing and marginal costs of production as a result of implementing COOL.

DIRECT SPECTROSCOPIC IDENTIFICATION OF THE ORIGIN OF 'GREEN FUZZY' EMISSION IN STAR-FORMING REGIONS  

Science Conference Proceedings (OSTI)

'Green fuzzies' or 'extended green objects' were discovered in the recent Spitzer GLIMPSE survey data. These extended sources have enhanced emission in the 4.5 {mu}m IRAC channel images (which are generally assigned to be green when making three-color RGB images from Spitzer data). Green fuzzies are frequently found in the vicinities of massive young stellar objects (MYSO), and it has been established that they are in some cases associated with outflows. Nevertheless, the spectral carrier(s) of this enhanced emission is (are) still uncertain. Although it has been suggested that Br {alpha}, H{sub 2}, [Fe II], and/or broad CO emission may be contributing to and enhancing the 4.5 {mu}m flux from these objects, to date there have been no direct observations of the 4-5 {mu}m spectra of these objects. Here we report on the first direct spectroscopic identification of the origin of the green fuzzy emission. We obtained spatially resolved L- and M-band spectra for two green fuzzy sources using NIRI on the Gemini North telescope. In the case of one source, G19.88 - 0.53, we detect three individual knots of green fuzzy emission around the source. The knots exhibit a pure molecular hydrogen line emission spectrum, with the 4.695 {mu}m {nu} = 0-0 S(9) line dominating the emission in the 4-5 {mu}m wavelength range, and no detected continuum component. Our data for G19.88 - 0.53 prove that green fuzzy emission can be due primarily to emission lines of molecular hydrogen within the bandpass of the IRAC 4.5 {mu}m channel. However, the other target observed, G49.27 - 0.34, does not exhibit any line emission and appears to be an embedded MYSO with a cometary UC H II region. We suggest that the effects of extinction in the 3-8 {mu}m wavelength range and an exaggeration in the color stretch of the 4.5 {mu}m filter in IRAC RGB images could lead to embedded sources such as this one falsely appearing 'green'.

Origin of instability by positive bias stress in amorphous Si-In-Zn-O thin film transistor  

Science Conference Proceedings (OSTI)

The origin of instability under positive bias stress (PBS) in amorphous Si-In-Zn-O (SIZO) thin film transistor (TFT) with different Si concentration has been investigated by x-ray photoelectron spectroscopy (XPS) and density of states (DOSs) analysis. It is found that stability of SIZO-TFT with 3 wt. % Si under PBS became more deteriorated than that of 1 wt. % Si incorporated SIZO-TFT due to the increased oxygen related trap distributed in energy range from conduction band to {approx}0.3 eV below the conduction band. The origin of instability under PBS was discussed in terms of oxygen related trap derived from DOSs and XPS analysis.

An Extreme Solar Event of 20 January 2005: Properties of the Flare and the Origin of Energetic Particles  

E-Print Network (OSTI)

The extreme solar and SEP event of 20 January 2005 is analyzed from two perspectives. Firstly, we study features of the main phase of the flare, when the strongest emissions from microwaves up to 200 MeV gamma-rays were observed. Secondly, we relate our results to a long-standing controversy on the origin of SEPs arriving at Earth, i.e., acceleration in flares, or shocks ahead of CMEs. All emissions from microwaves up to 2.22 MeV line gamma-rays during the main flare phase originated within a compact structure located just above sunspot umbrae. A huge radio burst with a frequency maximum at 30 GHz was observed, indicating the presence of a large number of energetic electrons in strong magnetic fields. Thus, protons and electrons responsible for flare emissions during its main phase were accelerated within the magnetic field of the active region. The leading, impulsive parts of the GLE, and highest-energy gamma-rays identified with pi^0-decay emission, are similar and correspond in time. The origin of the pi^0-decay gamma-rays is argued to be the same as that of lower energy emissions. We estimate the sky-plane speed of the CME to be 2000-2600 km/s, i.e., high, but of the same order as preceding non-GLE-related CMEs from the same active region. Hence, the flare itself rather than the CME appears to determine the extreme nature of this event. We conclude that the acceleration, at least, to sub-relativistic energies, of electrons and protons, responsible for both the flare emissions and the leading spike of SEP/GLE by 07 UT, are likely to have occurred simultaneously within the flare region. We do not rule out a probable contribution from particles accelerated in the CME-driven shock for the leading GLE spike, which seemed to dominate later on.

Improved Dosimetric and Clinical Outcomes With Intensity-Modulated Radiotherapy for Head-and-Neck Cancer of Unknown Primary Origin  

SciTech Connect

Purpose: To compare differences in dosimetric, clinical, and quality-of-life endpoints among a cohort of patients treated by intensity-modulated radiotherapy (IMRT) and conventional radiotherapy (CRT) for head-and-neck cancer of unknown primary origin. Methods and Materials: The medical records of 51 patients treated by radiation therapy for squamous cell carcinoma of the head and neck presenting as cervical lymph node metastasis of occult primary origin were reviewed. Twenty-four patients (47%) were treated using CRT, and 27 (53%) were treated using IMRT. The proportions of patients receiving concurrent chemotherapy were 54% and 63%, respectively. Results: The 2-year estimates of overall survival, local-regional control, and disease-specific survival for the entire patient population were 86%, 89%, and84%, respectively. There were no significant differences in any of these endpoints with respect to radiation therapy technique (p > 0.05 for all). Dosimetric analysis revealed that the use of IMRT resulted in significant improvements with respect to mean dose and V30 to the contralateral (spared) parotid gland. In addition, mean doses to the ipsilateral inner and middle ear structures were significantly reduced with IMRT (p < 0.05 for all). The incidence of severe xerostomia in the late setting was 58% and 11% among patients treated by CRT and IMRT, respectively (p < 0.001). The percentages of patients who were G-tube dependent at 6 months after treatment were 42% and 11%, respectively (p < 0.001). Conclusions: IMRT results in significant improvements in the therapeutic ratio among patients treated by radiation therapy for head-and-neck cancer of unknown primary origin.

A double-hexameric MCM2-7 complex is loaded onto origin DNA during licensing of eukaryotic DNA replication  

Science Conference Proceedings (OSTI)

During pre-replication complex (pre-RC) formation, origin recognition complex (ORC), Cdc6, and Cdt1 cooperatively load the 6-subunit mini chromosome maintenance (MCM2-7) complex onto DNA. Loading of MCM2-7 is a prerequisite for DNA licensing that restricts DNA replication to once per cell cycle. During S phase MCM2-7 functions as part of the replicative helicase but within the pre-RC MCM2-7 is inactive. The organization of replicative DNA helicases before and after loading onto DNA has been studied in bacteria and viruses but not eukaryotes and is of major importance for understanding the MCM2-7 loading mechanism and replisome assembly. Lack of an efficient reconstituted pre-RC system has hindered the detailed mechanistic and structural analysis of MCM2-7 loading for a long time. We have reconstituted Saccharomyces cerevisiae pre-RC formation with purified proteins and showed efficient loading of MCM2-7 onto origin DNA in vitro. MCM2-7 loading was found to be dependent on the presence of all pre-RC proteins, origin DNA, and ATP hydrolysis. The quaternary structure of MCM2-7 changes during pre-RC formation: MCM2-7 before loading is a single hexamer in solution but is transformed into a double-hexamer during pre-RC formation. Using electron microscopy (EM), we observed that loaded MCM2-7 encircles DNA. The loaded MCM2-7 complex can slide on DNA, and sliding is not directional. Our results provide key insights into mechanisms of pre-RC formation and have important implications for understanding the role of the MCM2-7 in establishment of bidirectional replication forks.

Origin of the Ocean on the Earth: Early Evolution of Water D/H in a Hydrogen-rich Atmosphere  

E-Print Network (OSTI)

The origin of the Earth's ocean has been discussed on the basis of deuterium/hydrogen ratios (D/H) of several sources of water in the solar system. The average D/H of carbonaceous chondrites (CC's) is known to be close to the current D/H of the Earth's ocean, while those of comets and the solar nebula are larger by about a factor of two and smaller by about a factor of seven, respectively, than that of the Earth's ocean. Thus, the main source of the Earth's ocean has been thought to be CC's or adequate mixing of comets and the solar nebula. However, those conclusions are correct only if D/H of water on the Earth has remained unchanged for the past 4.5 Gyr. In this paper, we investigate evolution of D/H in the ocean in the case that the early Earth had a hydrogen-rich atmosphere, the existence of which is predicted by recent theories of planet formation no matter whether the nebula remains or not. Then we show that D/H in the ocean increases by a factor of 2-9, which is caused by the mass fractionation during atmospheric hydrogen loss, followed by deuterium exchange between hydrogen gas and water vapor during ocean formation. This result suggests that the apparent similarity in D/H of water between CC's and the current Earth's ocean does not necessarily support the CC's origin of water and that the apparent discrepancy in D/H is not a good reason for excluding the nebular origin of water.

Probing the origin of cosmic-rays with extremely high energy neutrinos using the IceCube Observatory  

E-Print Network (OSTI)

We have searched for extremely high energy neutrinos using data taken with the IceCube detector between May 2010 and May 2012. Two neutrino induced particle shower events with energies around 1 PeV were observed, as reported previously. In this work, we investigate whether these events could originate from cosmogenic neutrinos produced in the interactions of ultra-high energy cosmic-rays with ambient photons while propagating through intergalactic space. Exploiting IceCube's large exposure for extremely high energy neutrinos and the lack of observed events above 100 PeV, we can rule out the corresponding models at more than 90% confidence level. The model independent quasi-differential 90% CL upper limit, which amounts to $E^2 \\phi_{\

Plate Tectonic Consequences of competing models for the origin and history of the Banda Sea subducted oceanic lithosphere  

E-Print Network (OSTI)

The Banda Arc, situated west of Irian Jaya and in the easternmost extension of the Sunda subduction zone system, reveals a characteristic bowl-shaped geometry in seismic tomographic images. This indicates that the oceanic lithosphere still remains attached to the surrounding continental margins of northern Australia and the Bird's Head microcontinent. Major controversies exist between authors proposing an allochthonous or autochthonous origin of the Bird's Head block. Either scenario has important implications for plate kinematic models aiming to reconstruct the tectonic evolution of the region and the late Jurassic seaoor spreading geometry of this now subducted Argo-Tanimbar-Seram (ATS) ocean basin. Wider implications affect the tectonic conguration of the Tethyan-Pacic realm, the distribution of plate boundaries as well as the shape and size of continental blocks which have been rifted off the northeastern Gondwana margin during the Late Jurassic and are now accreted to the SE Asia margin. We apply structu...

Two clocks in the PSR J0737--3039 binary system and their implications for the system's origin and evolution  

E-Print Network (OSTI)

As discussed elsewhere in these proceedings, the double pulsar system is a magnificent laboratory for gravitational physics and for studying pulsar magnetospheres. Here we consider the uses of having two clocks in the system in the context of its origin and evolution. We find that the ``standard'' evolutionary scenario involving spin-up of the first-born neutron star in an X-ray binary phase is consistent with the observed parameters. Equality of the spin-down ages of the two pulsars requires that the post-accretion spin period of A most likely lies in the range $16 \\lapp P_{\\rm 0,A} \\lapp 21$ ms. The likely age of the system is 30-70 Myr.
