A letter report issued by the Government Accountability Office with an abstract that begins "U.S. trade preference programs promote economic development in poorer nations by providing export opportunities. The Generalized System of Preferences, Caribbean Basin Initiative, Andean Trade Preference Act, and African Growth and Opportunity Act unilaterally reduce U.S. tariffs for many products from over 130 countries. However, three of these programs expire partially or in full this year, and Congress is exploring options as it considers renewal. GAO was asked to review the programs' effects on the United States and on foreign beneficiaries' exports and development, identify policy trade-offs concerning these programs, and evaluate the overall U.S. approach to preference programs. To address these objectives, we analyzed trade data, reviewed trade literature and program documents, interviewed U.S. officials, and did fieldwork in six countries."

A letter report issued by the Government Accountability Office with an abstract that begins "As requested, we provided for audits of the financial statements of the U.S. Senate Restaurants Revolving Fund (the Fund) for the fiscal years ended September 30, 2007, and 2006, by contracting with the independent public accounting firm of Clifton Gunderson LLP. The contract required that the audit be conducted in accordance with U.S. generally accepted government auditing standards and the joint GAO/President's Council on Integrity and Efficiency (PCIE) Financial Audit Manual."

A letter report issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service's (IRS) Business Systems Modernization (BSM) program is a multibillion-dollar, high-risk, highly complex effort that involves the development and delivery of a number of modernized systems that are intended to replace the agency's aging business and tax processing systems. As required by law, IRS submitted its fiscal year 2008 expenditure plan in August 2007 to congressional appropriations committees, requesting $235.8 million from the BSM account. GAO's objectives in reviewing the plan were to (1) determine whether it satisfied the conditions specified in the law, (2) determine IRS's progress in implementing prior expenditure plan review recommendations, and (3) provide additional observations about the plan and the BSM program. To accomplish the objectives, GAO analyzed the plan, reviewed related documentation, and interviewed IRS officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The Army's Future Combat System (FCS) requires a software-based advanced information network to meld people, sensors, and weapons into a cohesive fighting force. As software controls 95 percent of FCS's functionality, it determines the success or failure of the program. The Army contracted with the Boeing Company as a lead systems integrator (LSI) to define, develop and integrate FCS, including software development. GAO must by law report annually on FCS. This is one of two reports to meet this requirement. It addresses risks facing the development of network and software, the practices being used to manage software, and the timing of key network demonstrations. In conducting our work, GAO has contacted numerous DOD, Army, and contractor offices; reviewed technical documents on software and network development and plans; attended meetings; and spoken to Army and other officials on various aspects of FCS network and software development. GAO also performed detailed work at five FCS software developers."

A letter report issued by the Government Accountability Office with an abstract that begins "The Future Combat System (FCS) program--which comprises 14 integrated weapon systems and an advanced information network--is the centerpiece of the Army's effort to transition to a lighter, more agile, and more capable combat force. The substantial technical challenges, the Army's acquisition strategy, and the cost of the program are among the reasons why the program is recognized as needing special oversight and review. Section 211 of the National Defense Authorization Act for Fiscal Year 2006 requires GAO to report annually on the FCS program. This report includes an examination of (1) how the definition, development, and demonstration of FCS capabilities are proceeding, particularly in light of the go/no-go decision scheduled for 2009; (2) the Army's plans for making production commitments for FCS and any risks related to the completion of development; and (3) the estimated costs for developing and producing FCS."

A letter report issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency's (EPA) Integrated Risk Information System (IRIS) contains EPA's scientific position on the potential human health effects of exposure to more than 540 chemicals. IRIS is a critical component of EPA's capacity to support scientifically sound environmental decisions, policies, and regulations. GAO was asked to examine (1) the outcome of steps EPA has taken to ensure that IRIS contains current, credible chemical risk information, to address the backlog of ongoing assessments, and to respond to new requirements from the Office of Management and Budget (OMB); and (2) the potential effects of planned changes to the IRIS assessment process on EPA's ability to ensure that IRIS provides current, credible risk information. To do this work, GAO reviewed and analyzed EPA data and interviewed officials at relevant agencies."

A letter report issued by the Government Accountability Office with an abstract that begins "Many defense contractor employees work side-by-side with federal employees in Department of Defense (DOD) facilities performing substantially the same tasks affecting billions in DOD spending. Given concerns with protecting the integrity of DOD operations, GAO was asked to assess (1) how many contractor employees work in DOD offices and what type of mission-critical contracted services they perform, (2) what safeguards there are to prevent personal conflicts of interest for contractor employees when performing DOD's tasks, and (3) whether government and defense contractor officials believe additional safeguards are necessary. GAO reviewed conflicts of interest laws and policies and interviewed ethics officials and senior leaders regarding applicability to DOD federal and contractor employees. GAO judgmentally selected and interviewed officials at 21 DOD offices with large contractor workforces, and 23 of their contractors."

A letter report issued by the Government Accountability Office with an abstract that begins "A fundamental principle of military readiness is that the military must train as it intends to fight, and military training ranges allow the Department of Defense (DOD) to accomplish this goal. According to DOD officials, heightened focus on the application of environmental statutes has affected the use of its training areas. Since 2003, DOD has obtained exemptions from three environmental laws and has sought exemptions from three others. This report discusses the impact, if any, of (1) environmental laws on DOD's training activities and military readiness, (2) DOD's use of statutory exemptions from environmental laws on training activities, (3) DOD's use of statutory exemptions on the environment, and (4) the extent to which DOD has demonstrated the need for additional exemptions. To address these objectives, GAO visited 17 training locations; analyzed environmental impact and readiness reports; and met with officials at service headquarters, the Office of the Secretary of Defense, federal regulatory agencies, and nongovernmental environmental groups."

A letter report issued by the Government Accountability Office with an abstract that begins "Federal and Montana state agencies have long been entangled in controversy over bison leaving Yellowstone National Park. Some of these bison, as well as elk and other wildlife, have a contagious disease called brucellosis, which can cause pregnant animals to abort. Montana livestock owners and government officials fear that if bison are allowed to leave the park, the disease could spread to cattle, potentially threatening the economic health of the state's livestock industry. To help manage this issue, three federal and two state agencies have been implementing a bison management plan that they agreed to in 2000. This report discusses (1) the progress made in implementing the bison management plan and (2) the plan's soundness and the effectiveness of the agencies' implementation of it for managing bison-related issues in and near Yellowstone National Park. GAO reviewed documentation and research on bison and brucellosis and interviewed federal and state officials and key stakeholders."

The present report documents the results of Working Group 2: B, D and K decays, of the workshop on Flavor in the Era of the LHC, held at CERN from November 2005 through March 2007. With the advent of the LHC, we will be able to probe New Physics (NP) up to energy scales almost one order of magnitude larger than it has been possible with present accelerator facilities. While direct detection of new particles will be the main avenue to establish the presence of NP at the LHC, indirect searches will provide precious complementary information, since most probably it will not be possible to measure the full spectrum of new particles and their couplings through direct production. In particular, precision measurements and computations in the realm of flavor physics are expected to play a key role in constraining the unknown parameters of the Lagrangian of any NP model emerging from direct searches at the LHC. The aim of Working Group 2 was twofold: on one hand, to provide a coherent, up-to-date picture of the status of flavor physics before the start of the LHC; on the other hand, to initiate activities on the path towards integrating information on NP …

We use a Lagrangian dispersion model driven by a mesoscale model with four-dimensional data assimilation to simulate the dispersion of elemental carbon (EC) over a region encompassing Mexico City and its surroundings, the study domain for the 2006 MAX-MEX experiment, which was a component of the MILAGRO campaign. The results are used to identify periods when biomass burning was likely to have had a significant impact on the concentrations of elemental carbon at two sites, T1 and T2, downwind of the city, and when emissions from the Mexico City Metropolitan Area (MCMA) were likely to have been more important. They are also used to estimate the median ages of EC affecting the specific absorption of light, aABS, at 870 nm as well as to identify periods when the urban plume from the MCMA was likely to have been advected over T1 and T2. Values of aABS at T1, the nearer of the two sites to Mexico City, were smaller at night and increased rapidly after mid-morning, peaking in the mid-afternoon. The behavior is attributed to the coating of aerosols with substances such as sulfate or organic carbon during daylight hours, but such coating appears to be limited or absent at …

The program established a collaborative process with domestic industries for the purpose of sharing Navy-developed technology. Private sector businesses were educated so as to increase their awareness of the vast amount of technologies that are available, with an initial focus on technology applications that are related to the Hydrogen, Fuel Cells and Infrastructure Technologies (Hydrogen) Program of the U.S. Department of Energy. Specifically, the project worked to increase industry awareness of the vast technology resources available to them that have been developed with taxpayer funding. NAVSEA-Carderock and the Houston Advanced Research Center teamed with Nicholls State University to catalog NAVSEA-Carderock unclassified technologies, rated the level of readiness of the technologies and established a web based catalog of the technologies. In particular, the catalog contains technology descriptions, including testing summaries and overviews of related presentations.

This chapter of the report of the 'Flavour in the era of LHC' workshop discusses flavor related issues in the production and decays of heavy states at LHC, both from the experimental side and from the theoretical side. We review top quark physics and discuss flavor aspects of several extensions of the Standard Model, such as supersymmetry, little Higgs model or models with extra dimensions. This includes discovery aspects as well as measurement of several properties of these heavy states. We also present public available computational tools related to this topic.

Dipole modes have been shown to be successful diagnostics for the beam position in superconducting accelerating cavities at the Free Electron Laser in Hamburg (FLASH) facility at DESY. By help of downmixing electronics the signals from the two higher order mode (HOM) couplers mounted on each cavity are monitored. The calibration, based on singular value decomposition, is more complicated than in standard position monitors. Position like signals based on this calibration are currently being in the process of being included in the control system. A second setup based on digitizing the spectrum from the HOM couplers has been used for monitoring monopole modes. The beam phase with respect to the RF has been thus monitored. The position calibration measurements and phase monitoring made at the FLASH are presented.

In order to efficiently perform particle simulations in systems with widely varying magnetization, we have developed a 'drift-Lorentz mover', which interpolates between full particle dynamics and drift kinetics in such a way as to preserve a physically correct gyroradius and particle drifts for both large and small ratios of the timestep to the cyclotron period. In order to extend applicability of the mover to systems with plasma frequency exceeding the cyclotron frequency - such as one may have with fully neutralized drift compression of a heavy ion beam - we have developed an implicit version of the mover. A first step in this direction, in which the polarization charge was added to the field solver, was described previously. Here we describe a fully implicit algorithm (which is analogous to the direct-implicit method for conventional particle-in-cell simulation), a stability analysis of it, its implementation in the WARP code, and several tests of the resultant code. The fully implemented version is electrostatic; we are beginning development of an electromagnetic version, and describe also the status of that effort.
