A letter report issued by the Government Accountability Office with an abstract that begins "Pervasive and sustained computer-based attacks pose a potentially devastating impact to systems and operations and the critical infrastructures they support. Addressing these threats depends on effective partnerships between the government and private sector owners and operators of critical infrastructure. Federal policy, including the Department of Homeland Security's (DHS) National Infrastructure Protection Plan, calls for a partnership model that includes public and private councils to coordinate policy and information sharing and analysis centers to gather and disseminate information on threats to physical and cyber-related infrastructure. GAO was asked to determine (1) private sector stakeholders' expectations for cyber-related, public-private partnerships and to what extent these expectations are being met and (2) public sector stakeholders' expectations for cyber-related, public-private partnerships and to what extent these expectations are being met. To do this, GAO conducted surveys and interviews of public and private sector officials and analyzed relevant policies and other documents."

A letter report issued by the Government Accountability Office with an abstract that begins "Before the passage of federal environmental legislation in the 1970s and 1980s, Department of Defense (DOD) activities contaminated millions of acres of soil and water on and near DOD sites. The Environmental Protection Agency (EPA) has certain oversight authorities for cleaning up contaminants on federal property, and has placed 1,620 of the most contaminated sites--including 141 DOD installations--on its National Priorities List (NPL). As of February 2009, after 10 or more years on the NPL, 11 DOD installations had not signed the required interagency agreements (IAG) to guide cleanup with EPA. GAO was asked to examine (1) the status of DOD cleanup of hazardous substances at selected installations that lacked IAGs, and (2) obstacles, if any, to cleanup at these installations. GAO selected and visited three installations, reviewed relevant statutes and agency documents, and interviewed agency officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Adaptive housing assistance grants help eligible service members or veterans adapt or modify a residence to accommodate disabilities sustained through military service. The Veterans' Housing Opportunity and Benefits Improvement Act of 2006 authorized the Department of Veterans Affairs (VA) to expand its existing adaptive housing assistance grants to include eligible individuals temporarily living in a home owned by a family member, known as Temporary Residence Adaptation (TRA) grants. The act also mandated GAO to issue interim and final reports on VA's implementation of TRA. This final report examines (1) the characteristics of TRA grants and grantees and (2) what accounts for low utilization of the program and how to ensure that the program serves its intended recipients. To address these objectives, GAO analyzed VA data and documents and interviewed service members and veterans who both had and had not used the TRA grant."

A letter report issued by the Government Accountability Office with an abstract that begins "Airports are a vital part of the nation's air transportation system and face many similar challenges. In 2003, the Airport Cooperative Research Program (ACRP) was authorized to conduct applied research to help airport operators solve shared challenges that are not addressed by other federal research. As requested, this report addresses (1) the extent to which ACRP's processes reflect criteria for conducting a high-quality research program and (2) ACRP's results to date and their usefulness for the aviation community. GAO reviewed ACRP documentation and compared ACRP processes to criteria previously developed by GAO that can be applied to research programs. These criteria identify three phases of the applied research process and steps to help produce high-quality results. GAO also reviewed ACRP projects and publications and interviewed ACRP stakeholders and airport officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The American Recovery and Reinvestment Act of 2009 (Recovery Act), estimated to cost $862 billion over 10 years, is intended to stimulate the economy and create jobs. The Recovery Act provides funds to federal agencies and states, which in turn may award contracts to private companies and other entities to carry out the purposes of the Recovery Act. Contracts using Recovery Act funds are required to be awarded competitively to the maximum extent practicable. GAO was asked to examine the use and oversight of noncompetitive Recovery Act contracts at the federal and state levels. GAO determined (1) the extent that federal contracts were awarded noncompetitively; (2) the reasons five selected federal agencies (the Departments of Defense, Energy, and Health and Human Services; the National Aeronautics and Space Administration; and the Small Business Administration (SBA)) awarded noncompetitive contracts; (3) the oversight these agencies and their inspectors general (IG) provide for Recovery Act contracts; and (4) the level of insight five selected states (California, Colorado, Florida, New York, and Texas) have into the use of noncompetitive Recovery Act contracts."

Testimony issued by the Government Accountability Office with an abstract that begins "U.S. insular areas face serious economic and fiscal challenges and rely on federal funding to support their governments and deliver critical services. The Department of the Interior, through its Office of Insular Affairs (OIA), provides about $70 million in grants annually, including technical assistance grants, to increase insular area self-sufficiency. In the past, GAO and others have raised concerns regarding insular areas' internal control weaknesses, which increase the risk of grant fund mismanagement, fraud, and abuse. In March 2010, GAO reported on insular area grants (GAO-10-347); this testimony summarizes that report and focuses on (1) whether previously reported internal control weaknesses have been addressed and, if not, to what extent they are prevalent among OIA grant projects, including technical assistance grant projects, as of March 2010; and (2) the extent to which OIA has taken action to improve the implementation and management grant projects, as of March 2010. For the March 2010 report, GAO reviewed a random sample of 173 OIA grant project files and interviewed OIA and insular area officials. For this testimony, GAO conducted additional analysis for the 49 technical assistance grant projects included in the …

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses oversight of U.S. assistance programs in Afghanistan. Strengthening the Afghan economy through development assistance efforts is critical to the counterinsurgency strategy and a key part of the U.S Integrated Civilian-Military Campaign Plan for Afghanistan. Since fiscal year 2002, the U.S. Agency for International Development (USAID) has awarded over $11.5 billion in support of development assistance programs in Afghanistan. Since 2003, GAO has issued several reports and testimonies related to U.S. security, governance, and development efforts in Afghanistan. In addition to reviewing program planning and implementation, we have focused on efforts to ensure proper management and oversight of the U.S. investment, which are essential to reducing waste, fraud, and abuse. Over the course of this work, we have identified improvements that were needed, as well as many obstacles that have affected success and should be considered in program management and oversight. While drawing on past work relating to U.S. development efforts in Afghanistan, this testimony focuses on findings in our most recent report released yesterday on the USAID's management and oversight of its agricultural programs in Afghanistan. It will address (1) the challenges the United States …

A letter report issued by the Government Accountability Office with an abstract that begins "One of the most devastating aspects of the current financial crisis for homeowners is the prospect of losing their homes to foreclosure, and many homeowners have fallen victim to foreclosure rescue and loan modification schemes. In 2009, the administration created the Financial Fraud Enforcement Task Force (FFETF), which is led by the Department of Justice (DOJ), to combat these and other financial crimes. This report examines (1) the nature and prevalence of these schemes, (2) federal efforts coordinated to combat these schemes and other major efforts, and (3) factors that may affect federal efforts' success in combating these schemes. To address these objectives, GAO obtained information from federal agencies participating in the FFETF and interviewed representatives of five states with high exposure to potential foreclosures and nonprofit organizations undertaking related activities."

Stimulated by an acetate-amendment field experiment conducted in 2007, anaerobic microbial populations in the aquifer at the Rifle Integrated Field Research Challenge site in Colorado reduced mobile U(VI) to insoluble U(IV). During this experiment, planktonic biomass was sampled at various time points to quantitatively evaluate proteomes. In 2008, an acetate-amended field experiment was again conducted in a similar manner to the 2007 experiment. As there was no comprehensive metagenome sequence available for use in proteomics analysis, we systematically evaluated 12 different organism genome sequences to generate sets of aggregate genomes, or “pseudo-metagenomes”, for supplying relative quantitative peptide and protein identifications. Proteomics results support previous observations of the dominance of Geobacteraceae during biostimulation using acetate as sole electron donor, and revealed a shift from an early stage of iron reduction to a late stage of iron reduction. Additionally, a shift from iron reduction to sulfate reduction was indicated by changes in the contribution of proteome information contributed by different organism genome sequences within the aggregate set. In addition, the comparison of proteome measurements made between the 2007 field experiment and 2008 field experiment revealed differences in proteome profiles. These differences may be the result of alterations in abundance and population structure …

Electrofuels Project: MIT is using solar-derived hydrogen and common soil bacteria called Ralstonia eutropha to turn carbon dioxide (CO2) directly into biofuel. This bacteria already has the natural ability to use hydrogen and CO2 for growth. MIT is engineering the bacteria to use hydrogen to convert CO2 directly into liquid transportation fuels. Hydrogen is a flammable gas, so the MIT team is building an innovative reactor system that will safely house the bacteria and gas mixture during the fuel-creation process. The system will pump in precise mixtures of hydrogen, oxygen, and CO2, and the online fuel-recovery system will continuously capture and remove the biofuel product.

Electrofuels Project: MIT is using carbon dioxide (CO2) and hydrogen generated from electricity to produce natural oils that can be upgraded to hydrocarbon fuels. MIT has designed a 2-stage biofuel production system. In the first stage, hydrogen and CO2 are fed to a microorganism capable of converting these feedstocks to a 2-carbon compound called acetate. In the second stage, acetate is delivered to a different microorganism that can use the acetate to grow and produce oil. The oil can be removed from the reactor tank and chemically converted to various hydrocarbons. The electricity for the process could be supplied from novel means currently in development, or more proven methods such as the combustion of municipal waste, which would also generate the required CO2 and enhance the overall efficiency of MIT’s biofuel-production system.

How will the United States satisfy energy demand in a tightening global energy marketplace while, at the same time, reducing greenhouse gas emissions? Exascale computing -- expected to be available within the next eight to ten years ? may play a crucial role in answering that question by enabling a paradigm shift from test-based to science-based design and engineering. Computational modeling of complete power generation systems and engines, based on scientific first principles, will accelerate the improvement of existing energy technologies and the development of new transformational technologies by pre-selecting the designs most likely to be successful for experimental validation, rather than relying on trial and error. The predictive understanding of complex engineered systems made possible by computational modeling will also reduce the construction and operations costs, optimize performance, and improve safety. Exascale computing will make possible fundamentally new approaches to quantifying the uncertainty of safety and performance engineering. This report discusses potential contributions of exa-scale modeling in four areas of energy production and distribution: nuclear power, combustion, the electrical grid, and renewable sources of energy, which include hydrogen fuel, bioenergy conversion, photovoltaic solar energy, and wind turbines. Examples of current research are taken from projects funded by the U.S. …

Experiments in a number of conventional aspect ratio tokamaks have been successful in pacing edge localized modes (ELMs) by rapid vertical jogging of the plasma. This paper demonstrates the first pacing of ELMs in a spherical torus plasma. Applied 30 Hz vertical jogs synchronized the ELMs with the upward motion of the plasma. 45 Hz jogs also lead to an increase in the ELM frequency, though the synchronization of the ELMs and jogs was unclear. A reduction in the ELM energy was observed at the higher driven ELM frequencies. __________________________________________________

Photosynthetic assimilation of atmospheric carbon dioxide by land plants offers the underpinnings for terrestrial carbon (C) sequestration. A proportion of the C captured in plant biomass is partitioned to roots, where it enters the pools of soil organic C and soil inorganic C and can be sequestered for millennia. Bioenergy crops serve the dual role of providing biofuel that offsets fossil-fuel greenhouse gas (GHG) emissions and sequestering C in the soil through extensive root systems. Carbon captured in plant biomass can also contribute to C sequestration through the deliberate addition of biochar to soil, wood burial, or the use of durable plant products. Increasing our understanding of plant, microbial, and soil biology, and harnessing the benefits of traditional genetics and genetic engineering, will help us fully realize the GHG mitigation potential of phytosequestration.

This report covers the country-of-origin labeling (COOL) system implemented by the U.S. Department of Agriculture. Canada and Mexico say that the (COOL) system is unfair and does not meet its original objectives, while Congress is considering legislation that would further expand labeling requirements.

This report discusses the current political and economic conditions in Russia, focusing on the impact of Vladimir Putin's leadership and the leadership of his successor/protégé, Dmitriy Medvedev, both of which have steered Russia away from democratization. The report also discusses the state of the economy since the Soviet collapse in 1999, how the recent global economic downturn has affected Russia, the state of Russia's military, and the current relationship between Russia and the United States.

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses preventing and addressing government payment errors in the Medicare program. Medicare, which provides health insurance for those aged 65 and older and certain disabled persons, is susceptible to improper payments due to its size and complexity. Because the Medicare program has paid billions of dollars in error each year, the Centers for Medicare & Medicaid Services (CMS)--the agency that administers Medicare--conducts a number of activities to reduce improper payments. CMS administers the Medicare program with the help of Medicare claims administration contractors, which are not only responsible for processing and paying approximately 4.5 million claims per day, but for also conducting pre-payment reviews of claims to prevent improper payments before claims are paid, as well as post-payment reviews of claims potentially paid in error. To supplement these and other program integrity efforts, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 directed CMS to conduct a 3-year demonstration project on the use of a new type of contractors---recovery audit contractors (RAC)---in identifying underpayments and overpayments, and recouping overpayments in the Medicare program. The RAC demonstration program began in 2005. Subsequently, the Tax Relief and …

Sulfate-reducing bacteria have been extensively studied for their potential in heavy-metal bioremediation. However, the occurrence of elevated nitrate in contaminated environments has been shown to inhibit sulfate reduction activity. Although the inhibition has been suggested to result from the competition with nitrate-reducing bacteria, the possibility of direct inhibition of sulfate reducers by elevated nitrate needs to be explored. Using Desulfovibrio vulgaris as a model sulfate-reducing bacterium, functional genomics analysis reveals that osmotic stress contributed to growth inhibition by nitrate as shown by the upregulation of the glycine/betaine transporter genes and the relief of nitrate inhibition by osmoprotectants. The observation that significant growth inhibition was effected by 70 mM NaNO{sub 3} but not by 70 mM NaCl suggests the presence of inhibitory mechanisms in addition to osmotic stress. The differential expression of genes characteristic of nitrite stress responses, such as the hybrid cluster protein gene, under nitrate stress condition further indicates that nitrate stress response by D. vulgaris was linked to components of both osmotic and nitrite stress responses. The involvement of the oxidative stress response pathway, however, might be the result of a more general stress response. Given the low similarities between the response profiles to nitrate and other stresses, …
