A letter report issued by the Government Accountability Office with an abstract that begins "China is important to the global economy and a major U.S. trading partner. By joining the World Trade Organization (WTO) in 2001, China pledged to further liberalize its trade regime and follow global trade rules. While U.S.-Chinese commercial relations have expanded, controversies have emerged, including the size and growth of the U.S. trade deficit with China, China's lack of intellectual property protection, and China's implementation of its WTO obligations. Despite these challenges, China's vast consumer and labor markets present huge opportunities for U.S. exporters and investors. GAO (1) analyzed U.S. goods and services exports to China, (2) assessed how U.S. exports to China have fared against those of other major trading partners, and (3) analyzed U.S. investment and affiliate sales in China. We provided the Office of the U.S. Trade Representative, the Departments of Agriculture and Commerce, and the International Trade Commission with a draft of this report for their review and comment. These agencies chose to provide technical comments from their staff. We incorporated their suggestions as appropriate."

A letter report issued by the Government Accountability Office with an abstract that begins "Competitive sourcing is a management tool where federal agencies conduct competitions between federal employees and private companies to determine the best source to provide commercially available services. Concerns have been raised in the Congress that differences in the costs of federal and private health insurance benefits could disadvantage the federal workforce in public-private competitions. A health benefit cost comparability provision in the 2005 Defense Appropriations Act prohibited any advantage for private offerors that provide no health benefits or contribute less for them than the Department of Defense (DOD) contributes for its civilian employees. Legislation is pending to extend the provision for another year. GAO, in response to a mandate, determined (1) how DOD implemented the provision, and (2) what impact the provision had on DOD's fiscal year 2005 competitive sourcing program."

This project is organized under four major tasks (each of which has two or more subtasks) with contributions among the three collaborating organizations (MIT, INEEL and ANL-West): Task A: Core Physics and Fuel Cycle; Task B: Core Thermal Hydraulics; Task C: Plant Design Task; and D: Fuel Design.

LiH was one of the five primary shield materials the NRPCT intended to develop (along with beryllium, boron carbide, tungsten, and water) for potential Prometheus application. It was also anticipated that {sup 10}B metal would be investigated for feasibility at a low level of effort. LiH historically has been selected as a low mass, neutron absorption material for space shields (Systems for Nuclear Auxiliary Power (SNAP), Topaz, SP-100). Initial NRPCT investigations did not produce convincing evidence that LiH was desirable or feasible for a Prometheus mission due to material property issues (primarily swelling and hydrogen cover gas containment), and related thermal design complexity. Furthermore, if mass limits allowed, an option to avoid use of LiH was being contemplated to lower development costs and associated risks. However, LiH remains theoretically the most efficient neutron shield material per unit mass, and, with sufficient testing and development, could be an optimal material choice for future flights.

Testing forms a critical part of the development process for large-scale software, and there is growing need for automated tools that can read, represent, analyze, and transform the application's source code to help carry out testing tasks. However, the support required to compile applications written in common general purpose languages is generally inaccessible to the testing research community. In this paper, we report on an extensible, open-source compiler infrastructure called ROSE, which is currently in development at Lawrence Livermore National Laboratory. ROSE specifically targets developers who wish to build source-based tools that implement customized analyses and optimizations for large-scale C, C++, and Fortran90 scientific computing applications (on the order of a million lines of code or more). However, much of this infrastructure can also be used to address problems in testing, and ROSE is by design broadly accessible to those without a formal compiler background. This paper details the interactions between testing of applications and the ways in which compiler technology can aid in the understanding of those applications. We emphasize the particular aspects of ROSE, such as support for the general analysis of whole programs, that are particularly well-suited to the testing research community and the scale of the …

This report discusses immigration policy and expedited removal, an immigration enforcement strategy originally conceived to operate at the borders and ports of entry, recently has been expanded in certain border regions.

This report is organized to reflect the main border security issues relating to the movement of people into the country, as indicated by the legislation currently pending in the 109th Congress.

In the past three years, we followed the work plan as we suggested in the proposal and made every efforts to fulfill the project objectives. Based on our large amount of creative and productive work, including both of experimental and theoretic aspects, we received important technical breakthrough on naphthenic acid removal process and obtained deep insight on catalytic decarboxylation chemistry. In detail, we established an integrated methodology to serve for all of the experimental and theoretical work. Our experimental investigation results in discovery of four type effective catalysts to the reaction of decarboxylation of model carboxylic acid compounds. The adsorption experiment revealed the effectiveness of several solid materials to naphthenic acid adsorption and acidity reduction of crude oil, which can be either natural minerals or synthesized materials. The test with crude oil also received promising results, which can be potentially developed into a practical process for oil industry. The theoretical work predicted several possible catalytic decarboxylation mechanisms that would govern the decarboxylation pathways depending on the type of catalysts being used. The calculation for reaction activation energy was in good agreement with our experimental measurements.

Major, minor, and trace uranium isotopes were measured at Lawrence Livermore National Laboratory in environmentally acquired samples using different instruments to span large variations in concentrations. Multi-collector inductively-coupled plasma mass spectrometry (MC-ICPMS) can be used to measure major and minor isotopes: {sup 238}U, {sup 235}U, {sup 234}U and {sup 236}U. Accelerator mass spectrometry (AMS) can be used to measure minor and trace isotopes: {sup 234}U, {sup 236}U, and {sup 233}U. The main limit of quantification for minor or trace uranium isotopes is the abundance sensitivity of the measurement technique; i.e., the ability to measure a minor or trace isotope of mass M in the presence of a major isotope at M{+-}1 mass units. The abundance sensitivity for {sup 236}U/{sup 235}U isotope ratio measurements using MC-ICPMS is around {approx}2x10{sup -6}. This compares with a {sup 236}U/{sup 235}U abundance sensitivity of {approx}1x10{sup -7} for the current AMS system, with the expectation of 2-3 orders of magnitude improvement in sensitivity with the addition of another high energy filter. Comparing {sup 236}U/{sup 234}U from MC-ICPMS and AMS produced agreement within {approx}10% for samples at {sup 236}U levels high enough to be measurable by both techniques.

A letter report issued by the Government Accountability Office with an abstract that begins "Livestock producers, with gross income of $63 billion in 2004, depend on USDA's daily, weekly, and monthly livestock market news reports. These reports provide them and others in the industry with livestock and meat prices and volumes, which are helpful as they negotiate sales of cattle, hogs, lamb and meat products. Packers also use the average prices in these reports as a basis for paying some producers with whom the packers have contracts. In 1999, the Livestock Mandatory Reporting Act was passed to substantially increase the volume of industry sales transactions covered by USDA's market news reports and thereby encourage competition in the industry. In the context of ongoing discussions about the renewal of this act, GAO reviewed (1) USDA's efforts to ensure the quality of its livestock market news reports and (2) the coordination between two USDA agencies that are responsible for promoting competition in livestock markets."

The transient events of the {alpha}-{beta} martensitic transformation in nanocrystalline Ti films were explored via single shot electron diffraction patterns with 1.5 ns temporal resolution. The diffraction patterns were acquired with a newly constructed dynamic transmission electron microscope (DTEM), which combines nanosecond pulsed laser systems and pump-probe techniques with a conventional TEM. With the DTEM, the transient events of fundamental material processes, that are far too fast to be studied by conventional bulk techniques, can be captured in the form of electron diffraction patterns or images with nanosecond temporal resolution. The transient phenomena of the martensitic transformations in nanocrystalline Ti is ideally suited for study in the DTEM, with their rapid nucleation, characteristic interface velocities {approx}1 km/s, and significant irreversible microstructural changes. Free-standing 40-nm-thick Ti films were laser-heated at a rate of {approx}10{sup 10} K/s to a temperature above the 1155 K transition point, then probed at various time intervals with a 1.5-ns-long, intense electron pulse. Diffraction patterns show an almost complete transition to the {beta} phase within 500 ns. Postmortem analysis (after the sample is allowed to cool) shows a reversion to the {alpha} phase coupled with substantial grain growth, lath formation, and texture modification. The cooled material also …

A letter report issued by the Government Accountability Office with an abstract that begins "In 2003, Congress reauthorized HOPE VI, a program administered by the Department of Housing and Urban Development (HUD) and designed to improve the nation's worst public housing. In doing so, Congress required GAO to report on the extent of severely distressed public housing for the elderly and non-elderly persons with disabilities. "Severely distressed" is described in the statute as developments that, among other things, are a significant contributing factor to the physical decline of, and disinvestment in, the surrounding neighborhood; occupied predominantly by very low-income families, the unemployed, and those dependent on public assistance; have high rates of vandalism and criminal activity; and/or lack critical services, resulting in severe social distress. In response to this mandate, GAO examined (1) the extent to which public housing developments occupied primarily by elderly persons and non-elderly persons with disabilities are severely distressed and (2) the ways in which such housing can be improved. HUD officials provided oral comments indicating general agreement with the report."

Other written product issued by the Government Accountability Office with an abstract that begins "This document presents the results of GAO's survey of public housing agencies that manage developments that house primarily the elderly and non-elderly persons with disabilities. The purpose of the survey was to (1) collect data on physical and social characteristics that constitute aspects of "severe distress," (2) verify HUD data from the PIC and REAC databases, and (3) collect data about ways in which the stock of severely distressed public housing for the elderly and non-elderly persons with disabilities could be improved. We surveyed 46 public housing agencies that manage the 76 developments identified as potentially severely distressed using a mail questionnaire. Questions covered the following topics: physical deterioration, systems requiring renovation or modernization, the neighborhood environment in which the development was located, accessibility features, access to social and public services, and actions to remedy housing challenges. Each questionnaire contained a set of specific questions about the identified development and a set of general questions about public housing for the elderly and non-elderly persons with disabilities. In the 11 cases where the housing agency managed more than one of the identified 76 developments, respondents were asked …
