Most of the operations of federal departments and agencies are funded each year through the enactment of several regular appropriations acts. Since these bills are annual, expiring at the end of the fiscal year, regular bills for the subsequent fiscal year must be enacted by October 1st. Final action on some of the regular appropriations bills, however, are typically delayed beyond the deadline. When this occurs, the affected departments and agencies are generally funded under temporary continuing appropriations acts or resolutions until the final funding decisions become law.

We are developing a novel code that treats induced fission by statistical (or Monte-Carlo) simulation of individual decay chains. After its initial excitation, the fissionable compound nucleus may either deexcite by evaporation or undergo binary fission into a large number of fission channels each with different energetics involving both energy dissipation and deformed scission prefragments. After separation and Coulomb acceleration, each fission fragment undergoes a succession of individual (neutron) evaporations, leading to two bound but still excited fission products (that may further decay electromagnetically and, ultimately, weakly), as well as typically several neutrons. (The inclusion of other possible ejectiles is planned.) This kind of approach makes it possible to study more detailed observables than could be addressed with previous treatments which have tended to focus on average quantities. In particular, any type of correlation observable can readily be extracted from a generated set of events. With a view towards making the code practically useful in a variety of applications, emphasis is being put on making it numerically efficient so that large event samples can be generated quickly. In its present form, the code can generate one million full events in about 12 seconds on a MacBook laptop computer. The development …

We introduce a simple polar fluid model for the thermodynamics of dense supercritical water based on a Buckingham (exp-6) core and point dipole representation of the water molecule. The proposed exp6-polar thermodynamics, based on ideas originally applied to dipolar hard spheres, performs very well when tested against molecular dynamics simulations. Comparisons of the model predictions with experimental data available for supercritical water yield excellent agreement for the shock Hugoniot, isotherms and sound speeds, and are also quite good for the self-diffusion constant and relative dielectric constant. We expect the present approach to be also useful for other small polar molecules and their mixtures.

This document describes the test events and numbers of samples comprising the experimental design that was developed for the contamination, decontamination, and sampling of a building at the Idaho National Laboratory (INL). This study is referred to as the INL Sample Collection Operational Test. Specific objectives were developed to guide the construction of the experimental design. The main objective is to assess the relative abilities of judgmental and probabilistic sampling strategies to detect contamination in individual rooms or on a whole floor of the INL building. A second objective is to assess the use of probabilistic and Bayesian (judgmental + probabilistic) sampling strategies to make clearance statements of the form “X% confidence that at least Y% of a room (or floor of the building) is not contaminated. The experimental design described in this report includes five test events. The test events (i) vary the floor of the building on which the contaminant will be released, (ii) provide for varying or adjusting the concentration of contaminant released to obtain the ideal concentration gradient across a floor of the building, and (iii) investigate overt as well as covert release of contaminants. The ideal contaminant gradient would have high concentrations of contaminant in …

Weak scale supersymmetry provides elegant solutions to many of the problems of the standard model, but it also generically gives rise to excessive flavor and CP violation. We show that, if the mechanism that suppresses the Yukawa couplings also suppresses flavor changing interactions in the supersymmetry breaking parameters, essentially all the low energy flavor and CP constraints can be satisfied. The standard assumption of flavor universality in the supersymmetry breaking sector is not necessary. We study signatures of this framework at the LHC. The mass splitting among different generations of squarks and sleptons can be much larger than in conventional scenarios, and even the mass ordering can be changed. We find that there is a plausible scenario in which the next-to-lightest superparticle is a long-lived right-handed selectron or smuon which decays into the lightest superparticle, a gravitino. This leads to the spectacularsignature of monochromatic electrons or muons in a stopper detector, providing strong evidence for the framework.

The functional expansion technique (FET) was recently developed for Monte Carlo simulation. The basic idea of the FET is to expand a Monte Carlo tally in terms of a high order expansion, the coefficients of which can be estimated via the usual random walk process in a conventional Monte Carlo code. If the expansion basis is chosen carefully, the lowest order coefficient is simply the conventional histogram tally, corresponding to a flat mode. This research project studied the applicability of using the FET to estimate the fission source, from which fission sites can be sampled for the next generation. The idea is that individual fission sites contribute to expansion modes that may span the geometry being considered, possibly increasing the communication across a loosely coupled system and thereby improving convergence over the conventional fission bank approach used in most production Monte Carlo codes. The project examined a number of basis functions, including global Legendre polynomials as well as “local” piecewise polynomials such as finite element hat functions and higher order versions. The global FET showed an improvement in convergence over the conventional fission bank approach. The local FET methods showed some advantages versus global polynomials in handling geometries with discontinuous …

This report examines current political and economic conditions in Honduras as well as issues in Honduran-U.S. relations.

Bursts of ~60 kHz activity on Mirnov coils occur frequently in NSTX plasmas and these are accompanied by bursts of neutral beam ion loss over a range in pitch angles. These losses have been measured with a scintillator type loss probe imaged with a high speed (>10,000 frames/s) video camera, giving the evolution of the energy and pitch angle distributions of the lost neutral beam ions over the course of the events. The instability occurs below the TAE frequency in NSTX (~100 kHz) in high beta plasmas and may be a beta driven Alfvén acoustic (BAAE) mode.

Harper-Dorn (H-D) creep is observed in metals and geological materials exposed to very low stresses at temperatures close to the melting point. It is one of several types of creep processes wherein the steady-state strain rate is proportional to the applied stress, Nabarro-Herring creep and Coble creep being two other important processes. H-D creep can be somewhat insidious because the creep rates are much larger than those expected for Nabarro-Herring or Coble creep. Since the working conditions of structural components of power plants and propulsion systems, as well as the motion of the earth’s mantle all involve very low stresses, an understanding of the factors controlling H-D creep is critical in preventing failures associated with those higher-than-expected creep rates. The purpose of this investigation was to obtain missing microstructural information on the evolution of the dislocation structures during static annealing of materials with fcc, bcc and hcp structure and use obtained results to test predictive capabilities of the dislocation network theory of H-D creep. In our view the evolutionary processes during static annealing and during Harper-Dorn creep are intimately related. The materials used in this study were fcc aluminum, hcp zinc and bcc tin. All characterizations of dislocation structures, densities …

Testimony issued by the Government Accountability Office with an abstract that begins "As agencies across the federal government embark on large-scale organizational change needed to address 21st century challenges, there is a compelling need for leadership to provide the continuing, focused attention essential to completing these multiyear business-related transformations. At the same time, many agencies are suffering from a range of long-standing management problems that are undermining their ability to accomplish their missions and achieve results. One proposed approach to address these challenges is to have COO/ CMO positions in federal agencies. This statement is mostly drawn from GAO's report released today (GAO-08-34) that discusses criteria that can be used to determine the type of COO/CMO that ought to be established in federal agencies and strategies for implementing these positions. To do this, GAO reviewed four organizations with COO/CMO-type positions and convened a forum. GAO also discusses previous GAO work on DOD and DHS. GAO's report recommends that the Office of Management and Budget (OMB), working with the President's Management Council use the identified criteria when assessing the type of COO/CMO positions appropriate for federal agencies and the strategies for implementing these positions. Also, GAO suggests that Congress consider these …

LLNL proposes to obtain soil samples from the following areas: (1) Four areas downwind of the Explosives Waste Treatment Facility (EWTF) Burn Units (i.e., Thermal Treatment Unit and Burn Pan); (2) One area upwind of the Burn Units and Detonation Pad; (3) Two areas downwind of the EWTF Detonation Pad; and (4) Three areas unaffected (representing ambient conditions) by EWTF operations approximately 7000-8000 feet upwind of the facility. The purpose of the sampling in areas 1, 2, and 3 is to detect if operations cause increases in concentrations of materials downwind of the Burn Units or downwind of the Detonation Pad. The purpose of the sampling in area 4 is to determine if previously developed background screening levels can be applied to EWTF operations. A 20 foot diameter circle will define each sample area. Soil samples will be obtained from four random locations inside each 20 foot circle. The samples will be obtained immediately below the surface, free of any organic matter (e.g., roots) and other surface and subsurface material (e.g., rocks) that is not conducive to analysis. The random identification of four discrete sample locations in each circle will allow the variability between sample locations and areas, if present, …

The University Research Program in Robotics (URPR) is an integrated group of universities performing fundamental research that addresses broad-based robotics and automation needs of the NNSA Directed Stockpile Work (DSW) and Campaigns.

A letter report issued by the Government Accountability Office with an abstract that begins "Certified registered nurse anesthetists (CRNA), registered nurses who have completed a master's degree program in nurse anesthesia, provide the majority of anesthesia care veterans receive in VA medical facilities. While the demand for CRNAs is anticipated to increase, many CRNAs employed by VA--VA CRNAs--are nearing retirement eligibility age. Concerns have been raised about the challenges VA may face in maintaining its VA CRNA workforce. GAO (1) identified VA CRNA workforce challenges that VA medical facilities may experience related to VA CRNAs, (2) identified the key mechanisms that VA medical facilities can use to recruit and retain VA CRNAs, and (3) determined the extent to which facilities use the key mechanisms. To identify VA CRNA workforce challenges, GAO analyzed Web-based surveys it sent to VA chief anesthesiologists, VA human resources officers, and VA CRNAs, with survey response rates of 92, 85, and 76 percent, respectively. GAO also identified the key mechanisms VA medical facilities can use to recruit and retain VA CRNAs and the extent that these mechanisms are used."

Development of advanced hydrogen separation membranes in support of hydrogen production processes such as coal gasification and as front end gas purifiers for fuel cell based system is paramount to the successful implementation of a national hydrogen economy. Current generation metallic hydrogen separation membranes are based on Pd-alloys. Although the technology has proven successful, at issue is the high cost of palladium. Evaluation of non-noble metal based dense metallic separation membranes is currently receiving national and international attention. The focal point of the reported work was to evaluate two different classes of materials for potential replacement of conventional Pd-alloy purification/diffuser membranes. Crystalline V-Ni-Ti and Amorphous Fe- and Co-based metallic glass alloys have been evaluated using both electrochemical and gaseous hydrogen permeation testing techniques..

Testimony issued by the Government Accountability Office with an abstract that begins "U.S. Customs and Border Protection (CBP) is responsible for keeping terrorists and other dangerous people from entering the country while also facilitating the cross-border movement of millions of travelers. CBP carries out this responsibility at 326 air, sea, and land ports of entry. In response to a congressional request, GAO examined CBP traveler inspection efforts, the progress made, and the challenges that remain in staffing and training at ports of entry, and the progress CBP has made in developing strategic plans and performance measures for its traveler inspection program. To conduct its work, GAO reviewed and analyzed CBP data and documents related to inspections, staffing, and training, interviewed managers and officers, observed inspections at eight major air and land ports of entry, and tested inspection controls at eight small land ports of entry. GAO's testimony is based on a report GAO issued November 5, 2007."

The Structural Classification of Proteins (SCOP) database is a comprehensive ordering of all proteins of known structure, according to their evolutionary and structural relationships. The SCOP hierarchy comprises the following levels: Species, Protein, Family, Superfamily, Fold and Class. While keeping the original classification scheme intact, we have changed the production of SCOP in order to cope with a rapid growth of new structural data and to facilitate the discovery of new protein relationships. We describe ongoing developments and new features implemented in SCOP. A new update protocol supports batch classification of new protein structuresby their detected relationships at Family and Superfamily levels in contrast to our previous sequential handling of new structural data by release date. We introduce pre-SCOP, a preview of the SCOP developmental version that enables earlier access to the information on new relationships. We also discuss the impact of worldwide Structural Genomics initiatives, which are producing new protein structures at an increasing rate, on the rates of discovery and growth of protein families and superfamilies. SCOP can be accessed at http://scop.mrc-lmb.cam.ac.uk/scop.
