A letter report issued by the Government Accountability Office with an abstract that begins "About 5,000 people die and more than 120,000 are injured each year from crashes involving large trucks. The Federal Motor Carrier Safety Administration (FMCSA) has several enforcement programs to improve truck safety and funds similar enforcement programs in states through its Motor Carrier Safety Assistance Program (MCSAP). Following concern by Congress and others in 1999 that FMCSA's enforcement approach was ineffective, the agency committed to take stronger actions. This study reports on how FMCSA's enforcement approach has changed, how it makes decisions about its enforcement approach, and how it ensures that its grants to states contribute to the agency's mission of saving lives."

A letter report issued by the Government Accountability Office with an abstract that begins "Since the 1970s, the natural gas and electricity industries have each undergone a shift toward greater competition, referred to as restructuring. This restructuring has moved these industries from regulated monopolies to markets in which competitors vie for market share and wholesale prices are largely determined by supply and demand. Amid this restructuring, private companies have published information about these markets, including reports of market prices in various locations--referred to as price indices. These indices, whether for short-term "spot" or long-term "forward" markets, are developed by surveying selected market participants who voluntarily supply price information. Market participants rely on these price indices to help them make informed decisions about trading these commodities and to evaluate new investments. In recent years, confidence in price indices has been shaken due to misreporting and other abuses. During the energy crisis in the West in 2000-2001, several market participants were found to have purposefully misreported prices in order to manipulate these indices for financial gain. In this context, GAO agreed to answer the following questions: (1) What federal regulatory and statutory efforts have been taken to improve price indices in electricity …

A letter report issued by the Government Accountability Office with an abstract that begins "Inflammatory bowel disease (IBD) affects an estimated one million Americans. IBD patients often have difficulty digesting food. As a result, they may require parenteral nutrition (intravenous feeding) or enteral nutrition (tube feeding), medically necessary food products to supplement their diets, and medications. In addition, some IBD patients must care for their ostomies--surgically created openings for the discharge of digested food. IBD advocates have recently expressed concerns regarding the ability of IBD patients to obtain the health care they need. The Research Review Act of 2004 directed GAO to study the Medicare and Medicaid coverage standards for individuals with IBD, in both home health and outpatient delivery settings. GAO (1) identified the Medicare and Medicaid coverage standards for five key therapies used for the treatment of IBD and (2) determined what specific supplies used in these therapies Medicare and Medicaid programs will pay for. In this work, GAO examined Medicare's national and local coverage policies and conducted a survey of Medicaid programs in the 50 states and the District of Columbia."

A letter report issued by the Government Accountability Office with an abstract that begins "Because of the importance of the Department of Defense's (DOD) adherence to disciplined information technology (IT) acquisition processes in successfully modernizing its business systems, GAO was asked to determine whether the Transportation Coordinators' Automated Information for Movements System II (TC-AIMS II) program is being managed according to important aspects of DOD's acquisition policies and guidance, as well as other relevant acquisition management best practices. TC-AIMS II was initiated in 1995 as a joint services system to help manage force and equipment movements within the United States and abroad. The U.S. Department of the Army has the lead responsibility for managing the system's acquisition and estimates its life-cycle cost to be $1.7 billion over 25 years."

Correspondence issued by the Government Accountability Office with an abstract that begins "To provide for oversight of cost growth in DOD major defense acquisition programs, Congress passed legislation, commonly referred to as Nunn-McCurdy, which requires DOD to notify Congress when a program's unit cost growth exceeds (or breaches) the latest approved acquisition program baseline by at least 15 percent. If the cost growth has increased at least 25 percent over the baseline, the Secretary of Defense must certify to Congress that (1) the program is essential to national security; (2) no alternatives exist which will provide equal or greater military capability at less cost; (3) new program acquisition or procurement unit cost estimates are reasonable; and (4) the management structure is adequate to control unit cost. On April 13, 2005, the Acting Secretary of the Air Force formally notified Congress that the procurement unit cost of the Global Hawk had increased 18 percent over the baseline estimate. As requested, we are in the process of reviewing the acquisition strategies and requirements for several unmanned aircraft systems, including the Global Hawk. While that work will not be completed for some months, we are issuing this correspondence because we have developed important …

A letter report issued by the Government Accountability Office with an abstract that begins "Purchasing makes up a significant portion of annual expenses for the U.S. Postal Service (USPS). USPS has recently made significant changes to its purchasing regulations which, according to USPS, will result in a more businesslike purchasing process. Some stakeholders, including smaller suppliers who stated they rely on USPS for the majority of their business, have raised concerns about these changes. GAO was asked to (1) describe these changes, stakeholder views, and USPS's rationale for the changes and (2) assess how these changes reflect the principles of postal reform and practices of leading organizations and identify areas, if any, for continued oversight."

A chapter report issued by the Government Accountability Office with an abstract that begins "Congress and the President have called for various homeland security efforts to be based on risk management--a systematic process for assessing threats and taking appropriate steps to deal with them. GAO examined how three Department of Homeland Security (DHS) components were carrying out this charge: the Coast Guard, which has overall responsibility for security in the nation's ports; the Office for Domestic Preparedness (ODP), which awards grants for port security projects; and the Information Analysis and Infrastructure Protection Directorate (IAIP), which has responsibility for developing ways to assess risks across all types of critical infrastructure. GAO's work focused on identifying the progress each DHS component has made on risk management and the challenges each faces in moving further."

The CH-TRU Waste Content Codes (CH-TRUCON) document describes the inventory of the U.S. Department of Energy (DOE) CH-TRU waste within the transportation parameters specified by the Contact-Handled Transuranic Waste Authorized Methods for Payload Control (CH-TRAMPAC). The CH-TRAMPAC defines the allowable payload for the Transuranic Package Transporter-II (TRUPACT-II) and HalfPACT packagings. This document is a catalog of TRUPACT-II and HalfPACT authorized contents and a description of the methods utilized to demonstrate compliance with the CH-TRAMPAC. A summary of currently approved content codes by site is presented in Table 1. The CH-TRAMPAC describes "shipping categories" that are assigned to each payload container. Multiple shipping categories may be assigned to a single content code. A summary of approved content codes and corresponding shipping categories is provided in Table 2, which consists of Tables 2A, 2B, and 2C. Table 2A provides a summary of approved content codes and corresponding shipping categories for the "General Case," which reflects the assumption of a 60-day shipping period as described in the CH-TRAMPAC and Appendix 3.4 of the CH-TRU Payload Appendices. For shipments to be completed within an approximately 1,000-mile radius, a shorter shipping period of 20 days is applicable as described in the CH-TRAMPAC and Appendix 3.5 …

On behalf of the Department of Energy's Office of FreedomCAR and Vehicle Technologies, we are pleased to introduce the Fiscal Year (FY) 2004 Annual Progress Report for the Advanced Combustion Engine R&D Sub-Program. The mission of the FreedomCAR and Vehicle Technologies Program is to develop more energy efficient and environmentally friendly highway transportation technologies that enable Americans to use less petroleum for their vehicles. The Advanced Combustion Engine R&D Sub-Program supports this mission by removing the critical technical barriers to commercialization of advanced internal combustion engines for light-, medium-, and heavy-duty highway vehicles that meet future Federal and state emissions regulations. The primary objective of the Advanced Combustion Engine R&D Sub-Program is to improve the brake thermal efficiency of internal combustion engines from 30 to 45 percent for light-duty applications by 2010; and 40 to 55 percent for heavy-duty applications by 2012; while meeting cost, durability, and emissions constraints. R&D activities include work on combustion technologies that increase efficiency and minimize in-cylinder formation of emissions, as well as aftertreatment technologies that further reduce exhaust emissions. Work is also being conducted on ways to reduce parasitic and heat transfer losses through the development and application of thermoelectrics and turbochargers that include …

Depending upon final design and materials selections, a variety of engineering solutions may need to be considered to avoid chemical degradation of components in a notional space nuclear power plant (SNPP). Coatings are one engineered approach that was considered. A comprehensive review of protective coating technology for various space-reactor structural materials is presented, including refractory metal alloys [molybdenum (Mo), tungsten (W), rhenium (Re), tantalum (Ta), and niobium (Nb)], nickel (Ni)-base superalloys, and silicon carbide (Sic). A summary description of some common deposition techniques is included. A literature survey identified coatings based on silicides or iridium/rhenium as the primary methods for environmental protection of refractory metal alloys. Modified aluminide coatings have been identified for superalloys and multilayer ceramic coatings for protection of Sic. All reviewed research focused on protecting structural materials from extreme temperatures in highly oxidizing conditions. Thermodynamic analyses indicate that some of these coatings may not be protective in the high-temperature, impure-He environment expected in a Prometheus reactor system. Further research is proposed to determine extensibility of these coating materials to less-oxidizing or neutral environments.

We report on an experimental and theoretical study of thedynamic (ac) Stark effect on a for bidden transition. A general frameworkfor parameterizing and describing off-resonant ac-Stark shifts ispresented. A model is developed to calculate spectral line shapesresulting from resonant excitation of atoms in an intense standinglight-wave in the presence of off-resonant ac-Stark shifts. The model isused in the analysis and interpretation of a measurement of the ac-Starkshifts of the static-electric-field-induced 6s2 1S0 -->5d6s 3D1transition at 408 nm in atomic Yb. The results are in agreement withestimates of the ac-Stark shift of the transition under the assumptionthat the shift is dominated by that of the 6s2 1S0 ground state. Adetailed description of the experiment and analysis is presented. Abi-product of this work is an ind ependent determination (from thesaturation behavior of the 408-nm transition) of the Stark transitionpolarizability, which is found to be in agreement with our earliermeasurement. This work is part of the ongoing effort aimed at a precisionmeasurement of atomic parity-violation effects in Yb.

State-of-the-art climate models suggest that 20th Century ocean warming and sea-level rise were substantially reduced by the 1883 eruption of Krakatau. Volcanically induced cooling of the ocean surface penetrated into deeper layers where it persisted for decades. We find that volcanic eruptions have longer lasting effects than previously suspected, sufficient to offset a large fraction of ocean warming and sea-level rise caused by anthropogenic influences over the 20th Century. We examine the latest suite of coupled ocean-atmosphere model experiments that include time-varying external forcings (e.g., changes in greenhouse gases, solar irradiance, sulfate aerosols and volcanic aerosols) for the period 1880-2000 (see Methods). These models have differences in physics, resolution, initial conditions, 'spin-up' and ocean-atmosphere coupling procedures, as well as different combinations of external forcings. Uncertainties in both the applied forcings and in the model responses to them are therefore inherent in our investigation.

Axion fluctuations generated during inflation lead to isocurvature and non-Gaussian temperature fluctuations in the cosmic microwave background radiation. Following a previous analysis for the model independent string axion we consider the consequences of a measurement of these fluctuations for two additional string axions. We do so independent of any cosmological assumptions except for the axions being massless during inflation. The first axion has been shown to solve the strong CP problem for most compactifications of the heterotic string while the second axion, which does not solve the strong CP problem, obeys a mass formula which is independent of the axion scale. We find that if gravitational waves interpreted as arising from inflation are observed by the PLANCK polarimetry experiment with a Hubble constant during inflation of H{sub inf} {approx}> 10{sup 13} GeV the existence of the first axion is ruled out and the second axion cannot obey the scale independent mass formula. In an appendix we quantitatively justify the often held assumption that temperature corrections to the zero temperature QCD axion mass may be ignored for temperatures T {approx}< {Lambda}{sub QCD}.

Traditional compilers are limited in their ability to optimize applications for different architectures because statically modeling the effect of specific optimizations on different hardware implementations is difficult. Recent research has been addressing this issue through the use of empirical tuning, which uses trial executions to determine the optimization parameters that are most effective on a particular hardware platform. In this paper, we investigate empirical tuning of loop fusion, an important transformation for optimizing a significant class of real-world applications. In spite of its usefulness, fusion has attracted little attention from previous empirical tuning research, partially because it is much harder to configure than transformations like loop blocking and unrolling. This paper presents novel compiler techniques that extend conventional fusion algorithms to parameterize their output when optimizing a computation, thus allowing the compiler to formulate the entire configuration space for loop fusion using a sequence of integer parameters. The compiler can then employ an external empirical search engine to find the optimal operating point within the space of legal fusion configurations and generate the final optimized code using a simple code transformation system. We have implemented our approach within our compiler infrastructure and conducted preliminary experiments using a simple empirical search …
