A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Veterans Affairs (VA) operates one of the nation's largest health care systems. In 1999, GAO reported on VA's aged, obsolete capital assets, noting that better management of these assets could significantly reduce VA's operating costs. GAO further noted that VA could reinvest the savings to enhance veterans' health care services. In response, VA initiated its Capital Asset Realignment for Enhanced Services (CARES) process. Through CARES, VA identified what health care services it should provide and in which locations through 2022. The CARES process included assessing alternative ways to align inpatient services by closing or adding services at existing VA medical facilities or establishing new facilities. In May 2004, VA published its CARES decisions, but did not provide a national comprehensive summary of all its decisions about the alignment of inpatient services. GAO was asked to provide additional information about the inpatient service assessments and decisions made by VA. To provide a national, comprehensive summary, GAO summarized the locations where VA (1) identified a need to evaluate alternative ways to align inpatient health care service to improve quality, efficiency, or access and (2) made …

A letter report issued by the Government Accountability Office with an abstract that begins "The Social Security Administration (SSA) manages the two largest federal disability benefit programs and made approximately $75 billion in payments to about 8 million beneficiaries (ages 18 through 64) in 2003. Given the size of its programs, even small improvements in SSA's ability to return beneficiaries to work offer the potential for significant savings. Until recently, Social Security beneficiaries who needed help returning to work generally had to seek services from state vocational rehabilitation (VR) agencies. Few beneficiaries used these services or successfully returned to work. Therefore, Congress passed the Ticket to Work and Work Incentives Improvement Act of 1999 (Ticket Act, P.L. 106-170) to create a Ticket to Work and Self-Sufficiency Program (the Ticket program). The program's goals are to expand the availability of service providers and to help enable beneficiaries to return to work, become selfsufficient, and stop receiving disability benefit payments. Eligible beneficiaries can use their tickets as vouchers to request vocational rehabilitation, employment, or other support services from the traditional state VR agencies or from new SSA-approved public or private providers, which are referred to as employment networks (EN). The act required …

Testimony issued by the Government Accountability Office with an abstract that begins "People are critical to any agency transformation, such as the one envisioned for the Department of Homeland Security (DHS). They define an agency's culture, develop its knowledge base, and are its most important asset. Thus, strategic human capital management at DHS can help it marshal, manage, and maintain the people and skills needed to meet its critical mission. Congress provided DHS with significant flexibility to design a modern human capital management system. DHS and the Office of Personnel Management (OPM) have now jointly released the final regulations on DHS's new human capital system. Last year, with the release of the proposed regulations, GAO observed that many of the basic principles underlying the regulations were consistent with proven approaches to strategic human capital management and deserved serious consideration. However, some parts of the human capital system raised questions for DHS, OPM, and Congress to consider in the areas of pay and performance management, adverse actions and appeals, and labor management relations. GAO also identified multiple implementation challenges for DHS once the final regulations for the new system were issued. This testimony provides overall observations on DHS's intended human capital …

Testimony issued by the Government Accountability Office with an abstract that begins "The U.N. regular budget for the 2004-2005 biennium exceeded $3 billion for the first time. In light of the organization's increasing demands, the U.N. Secretary General and member states have called on the Secretariat to better define priorities and eliminate outdated activities. In response, the Secretary General launched major reform initiatives in 1997 and 2002, and we reported on the status of these efforts in February 2004. Audits and investigations of the U.N. Oil for Food program have also brought attention to recurring management weaknesses. As the largest financial contributor to the United Nations, the United States has a strong interest in the completion of the Secretary General's reforms. GAO provides observations on areas for U.N. reform based on our 2004 report and our continuing review of the Oil for Food program, including our analysis of internal audit reports and other documents."

Testimony issued by the Government Accountability Office with an abstract that begins "More than 34 million workers and retirees in about 30,000 singleemployer defined benefit plans rely on a federal insurance program managed by the Pension Benefit Guaranty Corporation (PBGC) to protect their pension benefits. However, the insurance program's long-term viability is in doubt and in July 2003 we placed the single-employer insurance program on our high-risk list of agencies with significant vulnerabilities for the federal government. In fiscal year 2004, PBGC's single-employer pension insurance program incurred a net loss of $12.1 billion for fiscal year 2004, and the program's accumulated deficit increased to $23.3 billion from $11.2 billion a year earlier. Further, PBGC estimated that underfunding in single-employer plans exceeded $450 billion as of the end of fiscal year 2004. This testimony provides GAO's observations on (1) some of the structural problems that limit PBGC's ability to protect itself from risk and (2) steps PBGC has taken to forecast and manage the risks that it faces."

This Soil Management Plan applies to all activities conducted under the auspices of the National Nuclear Security Administration (NNSA) Oak Ridge Y-12 National Security Complex (Y-12) that involve soil disturbance and potential management of waste soil. The plan was prepared under the direction of the Y-12 Environmental Compliance Department of the Environment, Safety, and Health Division. Soil disturbances related to maintenance activities, utility and building construction projects, or demolition projects fall within the purview of the plan. This Soil Management Plan represents an integrated, visually oriented, planning and information resource tool for decision making involving excavation or disturbance of soil at Y-12. This Soil Management Plan addresses three primary elements. (1) Regulatory and programmatic requirements for management of soil based on the location of a soil disturbance project and/or the regulatory classification of any contaminants that may be present (Chap. 2). Five general regulatory or programmatic classifications of soil are recognized to be potentially present at Y-12; soil may fall under one or more these classifications: (a) Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) pursuant to the Oak Ridge Reservation (ORR) Federal Facilities Agreement; (b) Resource Conservation and Recovery Act (RCRA); (c) RCRA 3004(u) solid waste managements units pursuant …

During the last eight years, we have worked on the general problems associated with grain boundaries in metals with DOE support. This final report summarizes the work that has been performed. At the start of this work, we took a much more atomistic approach to grain boundaries. However, as we performed this research it became clear that such approaches had the drawbacks listed above, and that we were not proceeding toward the more general understanding of grain boundaries that we have hoped to achieve. We then moved toward more macroscopic based experiments that we could use to understand the structure and motion of grain boundaries. From these we were able to begin deducing some of the most important results of this work and to provide information that can be used by others to understand the role of grain boundaries in materials. We thus present this report in a topical way and provide the experimental and theoretical underpinning that is needed at each point as we go forward.

In an x-ray driven reentrant cone fast ignition target the x-ray spectrum contains a high energy component that causes preheating of the reentrant cone and mixing of gold into the collapsing shell. Direct laser drive might avoid this problem.

EMSP supported research of millimeter-wave technology for nuclear waste glass melter monitoring has been very productive in establishing this field and showing great progress. This work has garnered significant recognition, winning an R&D 100 Award for viscosity monitoring, a Best Paper Award by the American Ceramic Society for nuclear waste glass monitoring, investment by the Glass Plus industry consortium to test this technology for glass fiber manufacture, investment by Savannah River Technology Center in purchasing key hardware components for additional tests, and Japanese initiated exchange visits between MIT and the vitrification facilities at Japanese Atomic Energy Research Institute (JAERI) in Tokai to review this technology. There are also potentially important spin offs to other areas including nuclear and fossil fuel power production, and National Institute of Health sponsored research as indicated below. Consequently, this work has the potential of becoming a major inter nationally recognized EMSP success story. A summary of the main accomplishments follows. The readers are referred to the cited reference publications for more details, many of which were EMSP supported by this work.

This abstract presents current collaborative work on the development of a stage system for accurate nanometer level positioning for scanning specimens spanning an area of 50 mm x 50 mm. The completed system employs a coarse/fine approach which comprises a short-range, six degree-of-freedom fine-motion platform (5 microns 200 micro-radians) carried by a long-range, two-axis X-Y coarse positioning system. Relative motion of the stage to a fixed metrology frame will be measured using a heterodyne laser in an eight-pass interferometer configuration. The final stage system will be housed in a vacuum environment and operated in a temperature-controlled laboratory. Results from a simple single coarse/fine axis system will be the design basis for the final multi-axis system. It is expected that initial stage performance evaluation will be presented at the conference.

In this paper we extend the difference formulation for radiation transport to the case of a single atomic line. We examine the accuracy, performance and stability of the difference formulation within the framework of the Symbolic Implicit Monte Carlo method. The difference formulation, introduced for thermal radiation by some of the authors, has the unique property that the transport equation is written in terms that become small for thick systems. We find that the difference formulation has a significant advantage over the standard formulation for a thick system. The correct treatment of the line profile, however, requires that the difference formulation in the core of the line be mixed with the standard formulation in the wings, and this may limit the advantage of the method. We bypass this problem by using the gray approximation. We develop three Monte Carlo solution methods based on different degrees of implicitness for the treatment of the source terms, and we find only conditional stability unless the source terms are treated fully implicitly.

We present a search for long-lived doubly-charged Higgs bosons (H{sup {+-}{+-}}), with signatures of high ionization energy loss and muon-like penetration. We use 292 pb{sup -1} of data collected in p{bar p} collisions at {radical}s = 1.96 TeV by the CDF II detector at the Fermilab Tevatron. Observing no evidence of long-lived doubly-charged particle production, we exclude H{sub L}{sup {+-}{+-}} and H{sub R}{sup {+-}{+-}} bosons with masses below 133 GeV/c{sup 2} and 109 GeV/c{sup 2}, respectively. In the degenerate case we exclude H{sup {+-}{+-}} mass below 146 GeV/c{sup 2}. All limits are quoted at the 95% confidence level.

The transport of chemicals or heat in fractured reservoirs is strongly affected by the fracture-matrix interfacial area. In a vapor-dominated geothermal reservoir, this area can be estimated by inert gas tracer tests, where gas diffusion between the fracture and matrix causes the tracer breakthrough curve (BTC) to have a long tail determined by the interfacial area. For water-saturated conditions, recent studies suggest that sorbing solute tracers can also generate strong tails in BTCs that may allow a determination of the fracture-matrix interfacial area. To theoretically explore such a useful phenomenon, this paper develops an analytical solution for BTCs in slug-tracer tests in a water-saturated fractured reservoir. The solution shows that increased sorption should have the same effect on BTCs as an increase of the diffusion coefficient. The solution is useful for understanding transport mechanisms, verifying numerical codes, and for identifying appropriate chemicals as tracers for the characterization of fractured reservoirs.

The Iran Nonproliferation Act of 2000 (INA) was enacted to help stop foreign transfers to Iran of weapons of mass destruction, missile technology, and advanced conventional weapons technology, particularly from Russia. Section 6 of the INA bans U.S. payments to Russia in connection with the International Space Station (ISS) unless the U.S. President determines that Russia is taking steps to prevent such proliferation. The ISS is currently under construction in orbit. According to current plans, the National Aeronautics and Space Administration (NASA) will become dependent on Russia for certain ISS crew-related services beginning in April 2006 for which NASA must pay. Thus, the INA could significantly affect U.S. utilization of ISS. This report outlines the history of INA, its effect on Russian and Iranian proliferation, its impact on the ISS program, and options for resolving associated issues.

This report outlines the Administration’s FY2006 budget request for the U.S. Department of Agriculture (USDA), including estimated outlays of $94.6 billion. Discretionary budget authority would fall 12% from FY2005 levels to $19.4 billion ($21 billion outlays), and mandatory outlays would remain steady at $73 billion. The request included proposals to reduce mandatory spending for farm commodity programs, food stamps, rural development, and conservation.

This report briefly discusses the Bush Administration's proposal to reduce the deficit between FY2004 and FY2009. It discusses the provisions of the FY2006 budget proposal in respect to the Administration's deficit reduction goal. CRS has constructed a modified baseline budget which, arguably, provides a “best guess” of the path of future deficits if current policy is extended. Under this alternative, the deficit is projected to rise to $425 billion in FY2009.

The federal budget deficit in FY2004 was 3.6% of gross domestic product (GDP). When the influence of economic conditions and temporary factors is excluded from the measurement of budget balances, the FY2004 deficit was 2.6% of GDP. By either measure, the deficit is above the historical average for the last 50 years.
