This report discusses the current political state of Iran and its relationship with the United States. This report emphasizes in particular the Iranian presidential elections that took place on June 12, 2009; current U.S. efforts under President Obama to forge diplomatic talks with Iran while at the same time urging aggressive action in the way of certain economic and trade sanctions; and how current U.S. efforts under the Obama Administration differ and/or are similar to efforts under the Bush Administration.

A letter report issued by the Government Accountability Office with an abstract that begins "Since 2000, the U.S. government has provided a total of $3.3 billion to Colombia, making it the fifth largest recipient of U.S. assistance. Part of this funding has gone toward nonmilitary assistance to Colombia, including programs to (1) promote legitimate economic alternatives to coca and opium poppy; (2) assist Colombia's vulnerable groups, particularly internally displaced persons; and (3) strengthen the country's democratic, legal, and security institutional capabilities. GAO examined these programs' objectives, reported accomplishments, and identified the factors, if any, that limit project implementation and sustainability. We also examined the challenges faced by Colombia and the United States in continuing to support these programs."

A letter report issued by the Government Accountability Office with an abstract that begins "Each year, about 2.5 million people file claims with the Social Security Administration (SSA) for disability benefits. If the claim is denied at the initial level, the claimant may appeal to the hearings level. The hearings level has allowed more than half of all appealed claims, an allowance rate that has raised concerns about the consistency of decisions made at the two levels. To help ensure consistency, SSA began a "process unification" initiative in 1994 and recently announced a new proposal to strengthen its disability programs. This report examines (1) the status of SSA's process unification initiative, (2) SSA's assessments of possible inconsistencies in decisions between adjudication levels, and (3) whether SSA's new proposal incorporates changes to improve consistency in decisions between adjudication levels."

A letter report issued by the Government Accountability Office with an abstract that begins "In its role as the nation's tax collector, the Internal Revenue Service (IRS) has a demanding responsibility in annually collecting trillions of dollars in taxes, processing hundreds of millions of tax and information returns, and enforcing the nation's tax laws. Since its first audit of IRS's financial statements in fiscal year 1992, GAO has identified a number of weaknesses in IRS's financial management operations. In related reports, GAO has recommended corrective action to address those weaknesses. Each year, as part of the annual audit of IRS's financial statements, GAO not only makes recommendations to address any new weaknesses identified but also follows up on the status of weaknesses GAO identified in previous years' audits. The purpose of this report is to (1) assist IRS management in tracking the status of audit recommendations and actions needed to fully address them and (2) demonstrate how the recommendations relate to control activities central to IRS's mission and goals."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) expects the cost to develop and procure the major weapon systems in its current portfolio to total $1.6 trillion. With increased competition for funding within DOD and across the federal government, effectively managing these acquisitions is critical. Yet DOD programs too often experience poor outcomes--like increased costs and delayed fielding of needed capabilities to the warfighter. In 2006, this Committee mandated that GAO report on DOD's processes for identifying needs and allocating resources for its weapon system programs. In 2007, GAO reported that DOD consistently commits to more programs than it can support. This follow-on report assesses DOD's funding approach, identifies key factors that influence the effectiveness of this approach, and identifies practices that could help improve DOD's approach. To conduct its work, GAO assessed 20 major weapon programs in DOD's current portfolio--5 in detail--and reviewed relevant DOD policy and guidance, prior GAO work, and other relevant literature. GAO also reviewed the practices of selected successful companies."

A letter report issued by the Government Accountability Office with an abstract that begins "Decontaminating and decommissioning the nation's uranium enrichment plants, which are contaminated with hazardous materials, will cost billions of dollars and could span decades. In 1992, the Energy Policy Act created the Uranium Enrichment Decontamination and Decommissioning Fund (Fund) to pay for the plants' cleanup and to reimburse licensees of active uranium and thorium processing sites for part of their cleanup costs. This report discusses (1) what DOE has done to reduce the cleanup costs authorized by the Fund, and (2) the extent to which the Fund is sufficient to cover authorized activities."

A letter report issued by the General Accounting Office with an abstract that begins "The Comptroller General convened a forum in September 2002 to identify useful practices and lessons learned from major private and public sector mergers, acquisitions, and organizational transformations. This was done to help federal agencies implement successful transformations of their cultures, as well as the new Department of Homeland Security merge its various originating components into a unified department. There was general agreement on a number of key practices found at the center of successful mergers, acquisitions, and transformations. In this report, we identify the specific implementation steps for the key practices raised at the forum with illustrative private and public sector examples. To identify these implementation steps and examples, we relied primarily on interviews with selected forum participants and other experts about their experiences implementing mergers, acquisitions, and transformations and also conducted a literature review."

A letter report issued by the General Accounting Office with an abstract that begins "The Department of Veterans Affairs (VA) provides graduate medical education (GME) to as many as one-third of U.S. resident physicians, but oversight responsibilities spread across VA's organizational components and multiple affiliated hospitals and medical schools could allow supervision problems to go undetected or uncorrected. GAO was asked to examine VA's procedures for (1) monitoring VA medical centers' adherence to VA's requirements for resident supervision, (2) using evaluations of supervision by GME accrediting bodies and residents, and (3) using information about resident supervision drawn from VA's programs for monitoring the quality and outcomes of patient care."

A letter report issued by the Government Accountability Office with an abstract that begins "From fiscal year 2003 through fiscal year 2009, the Department of Homeland Security (DHS) allocated about $5 billion for the Urban Area Security Initiative (UASI) grant program to enhance regional preparedness capabilities in the nation's highest risk urban areas (UASI regions). The Federal Emergency Management Agency (FEMA) administers this program. The Implementing Recommendations of the 9/11 Commission Act of 2007 (9/11 Act) required FEMA to change the size of the geographical areas used to assess UASI regions' risk. The conference report accompanying the Consolidated Appropriations Act for fiscal year 2008 directed GAO to assess FEMA's efforts to build regional preparedness through the UASI program, and determine how the 9/11 Act change affected UASI regions. This report addresses (1) the extent to which FEMA assesses how UASI regions' collaborative efforts build preparedness capabilities, and (2) how UASI officials described their collaboration efforts and changes resulting from the 9/11 Act. GAO surveyed all 49 UASI regions that received funding prior to the 9/11 Act change, and visited 6 regions selected based on factors such as length of participation. GAO also reviewed FEMA's grant guidance and monitoring systems."

In February and March 2009, the Obama Administration announced its overall plans to increase troop levels in Afghanistan and decrease troop levels in Iraq for 2009 through 2011. Using several Department of Defense (DOD) data reports, this report describes, analyzes, and estimates deployed troop strength from the 9/11 attacks to FY2012 to provide Congress with a tool to assess current and future DOD war funding requests; implications for the U.S. military presence in the region; and deployment burdens on individual service members and each of the services.

Trafficking in persons (TIP) for the purposes of exploitation is believed to be one of the most prolific areas of international criminal activity and is of significant concern to the United States and the international community. This report discusses the global and ongoing problem of TIP in detail, as well as anti-TIP programs and U.S. and international efforts to combat TIP.

This report discusses the mission of the North Atlantic Treaty Organization (NATO) in Afghanistan, the purpose of which is to stabilize and reconstruct Afghanistan by combating emerging threats such as terrorism and the proliferation of weapons of mass destruction. This report also discusses how the Obama Administration has made the Afghanistan conflict a policy priority, and what this stance could mean for potential future endeavors.

The world has entered a global recession that is causing widespread business contraction, increases in unemployment, and shrinking government revenues. The process for coping with the crisis by countries across the globe has been manifest in four basic phases. The first has been intervention to contain the contagion and restore confidence in the system. The second has been coping with the secondary effects of the crisis, particularly the global recession and flight of capital from countries in emerging markets and elsewhere that have been affected by the crisis. The third phase of this process is to make changes in the financial system to reduce risk and prevent future crises. The fourth phase of the process is dealing with political, social, and security effects of the financial turmoil. The role for Congress in this financial crisis is multifaceted. This report describes this role, as well as the financial crisis in general, in detail.

With increasing concentrations of carbon dioxide (CO2) in the atmosphere, the extent of effects on the ocean and marine resources is an increasing concern. One aspect of this issue is the ongoing process whereby seawater becomes acidified (i.e., ocean acidification) as more CO2 dissolves in it, causing hydrogen ion concentration in seawater to increase. While not yet fully understood, the ecological and economic consequences of ocean acidification could be substantial. Congress is beginning to focus attention on better understanding ocean acidification and determining how this concern might be addressed.

In view of the growing impact of hedge funds on a variety of financial markets, the Securities and Exchange Commission (SEC) in October 2004 adopted a regulation that requires hedge funds to register as investment advisers, disclose basic information about their operations, and open their books for inspection. The regulation took effect in February 2006, but on June 23, 2006, a court challenge was upheld and the rule was vacated. S. 1402 and H.R. 2586 would reinstate the SEC's authority. H.R. 2683 would require defined benefit pension plans to disclose investments in hedge funds. In December 2006, the SEC proposed raising the "accredited investor" standard - to be permitted to invest in hedge funds, an investor would need $2.5 million in assets, instead of $1 million.

Ground-water withdrawal estimates from 1913 through 2003 for the Death Valley regional ground-water flow system are compiled in an electronic database to support a regional, three-dimensional, transient ground-water flow model. This database updates a previously published database that compiled estimates of ground-water withdrawals for 1913–1998. The same methodology is used to construct each database. Primary differences between the 2 databases are an additional 5 years of ground-water withdrawal data, well locations in the updated database are restricted to Death Valley regional ground-water flow system model boundary, and application rates are from 0 to 1.5 feet per year lower than original estimates. The lower application rates result from revised estimates of crop consumptive use, which are based on updated estimates of potential evapotranspiration. In 2003, about 55,700 acre-feet of ground water was pumped in the DVRFS, of which 69 percent was used for irrigation, 13 percent for domestic, and 18 percent for public supply, commercial, and mining activities.

One of the major risks associated with underground coal gasification is contamination of local aquifers with a variety of toxic compounds. It is likely that the rate, volume, extent, and concentrations of contaminant plumes will depend on the local permeability field near the point of gasification. This field depends heavily on the geological history of stratigraphic deposition and the specifics of stratigraphic succession. Some coals are thick and isolated, whereas others are thinner and more regionally expressed. Some coals are overlain by impermeable units, such as marine or lacustrine shales, whereas others are overlain by permeable zones associated with deltaic or fluvial successions. Rapid stratigraphic characterization of the succession provides first order information as to the general risk of contaminant escape, which provides a means of ranking coal contaminant risks by their depositional context. This risk categorization could also be used for ranking the relative risk of CO{sub 2} escape from injected coal seams. Further work is needed to verify accuracy and provide some quantification of risks.

New global MHD eigenmode solutions arising in gaps in the low frequency Alfvén -acoustic continuum below the geodesic acoustic mode (GAM) frequency have been found numerically and have been used to explain relatively low frequency experimental signals seen in NSTX and JET tokamaks. These global eigenmodes, referred to here as Beta-induced Alfvén-Acoustic Eigenmodes (BAAE), exist in the low magnetic safety factor region near the extrema of the Alfvén-acoustic continuum. In accordance to the linear dispersion relations, the frequency of these modes shifts as the safety factor, q, decreases. We show that BAAEs can be responsible for observations in JET plasmas at relatively low beta < 2% as well as in NSTX plasmas at relatively high beta > 20%. In contrast to the mostly electrostatic character of GAMs the new global modes also contain an electromagnetic (magnetic field line bending) component due to the Alfvén coupling, leading to wave phase velocities along the field line that are large compared to the sonic speed. Qualitative agreement between theoretical predictions and observations are found.

We examine the possibility of using the standard Newton's method for solving a class of nonlinear eigenvalue problems arising from electronic structure calculation. We show that the Jacobian matrix associated with this nonlinear system has a special structure that can be exploited to reduce the computational complexity of the Newton's method. Preliminary numerical experiments indicate that the Newton's method can be more efficient for small problems in which a few smallest eigenpairs are needed.

The Biotelemetry System for Epilepsy Seizure Control Project developed and tested an automated telemetry system for use in an epileptic seizure prevention device that precisely controls localized brain temperature. This project was a result of a Department of Energy (DOE) Global Initiatives for Proliferation Prevention (GIPP) grant to the Kansas City Plant (KCP), Argonne National Laboratory (ANL), and Pacific Northwest National Laboratory (PNNL) to partner with Flint Hills Scientific, LLC, Lawrence, KS and Biophysical Laboratory Ltd (BIOFIL), Sarov, Russia to develop a method to help control epileptic seizures.
