Aviation Safety: FAA Needs to Strengthen the Management of Its Designee Programs
A letter report issued by the Government Accountability Office with an abstract that begins "The safety of the flying public and the reliability of the nation's aircraft depend, in part, on the Federal Aviation Administration's (FAA) regulation and certification of the aviation industry. FAA delegates the vast majority of its safety certification activities to about 13,600 private persons and organizations, known as "designees," which are currently grouped into 18 different programs. Among other tasks, designees perform physical examinations to ensure that pilots are medically fit to fly and examine the airworthiness of aircraft. GAO reviewed (1) the strengths of FAA's designee programs, (2) the weaknesses of those programs and factors contributing to those weaknesses, and (3) potential improvements to the programs."

Medicare Physician Payments: Concerns about Spending Target System Prompt Interest in Considering Reforms
A letter report issued by the Government Accountability Office with an abstract that begins "Concerns were raised about the current system Medicare uses to determine annual changes to physician fees--the sustainable growth rate (SGR) system--when fees were reduced by 5.4 percent in 2002. Subsequent administrative and legislative actions modified or overrode the SGR system, resulting in fee increases for 2003, 2004, and 2005. However, projected fee reductions for 2006-2012 have raised new concerns about the SGR system. Policymakers are considering whether to eliminate spending targets or modify them. The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) required that GAO study SGR and potential alternatives to the system. This report examines (1) how the SGR system is designed to control spending for physician services, (2) what concerns have been raised about the SGR system and its components, (3) what affects the stability and predictability of physician fee updates under the SGR system, and (4) what alternatives to the current SGR system exist. GAO reviewed relevant laws and regulations and interviewed officials and organizations representing physicians. On the basis of this information, GAO identified potential alternatives to the SGR system and requested illustrative simulations of fee updates and spending …

Federal Research: Opportunities Exist to Improve the Management and Oversight of Federally Funded Research and Development Centers
A letter report issued by the Government Accountability Office with an abstract that begins "In 2006, the federal government spent $13 billion--14 percent of its research and development (R&D) expenditures--to enable 38 federally funded R&D centers (FFRDCs) to meet special research needs. FFRDCs--including laboratories, studies and analyses centers, and systems engineering centers--conduct research in military space programs, nanotechnology, microelectronics, nuclear warfare, and biodefense countermeasures, among other areas. GAO was asked to identify (1) how federal agencies contract with organizations operating FFRDCs and (2) agency oversight processes used to ensure that FFRDCs are well-managed. GAO's work is based on a review of documents and interviews with officials from eight FFRDCs sponsored by the departments of Defense (DOD), Energy (DOE), Health and Human Services (HHS), and Homeland Security (DHS). What GAO Recommends"

Immigration Enforcement: DHS Has Incorporated Immigration Enforcement Objectives and Is Addressing Future Planning Requirements
A letter report issued by the Government Accountability Office with an abstract that begins "The former Immigration and Naturalization Service (INS) had five interior (non-border-related) immigration enforcement objectives to address federal immigration law violations: identify and remove criminal aliens from the United States; deter and dismantle alien trafficking and smuggling; respond to community reports and complaints about illegal immigration; minimize immigration benefit fraud; and block employers' access to undocumented workers. After the terrorist attacks of September 11, 2001, the INS and other federal agencies began merging their law enforcement functions into the U.S. Bureau of Immigration and Customs Enforcement (ICE) within the Department of Homeland Security. Congress sought information on how the newly formed ICE was addressing legacy INS's immigration enforcement objectives. GAO addressed the following questions: (1) What is the status of ICE's efforts to incorporate legacy INS's interior immigration enforcement objectives? (2) How is ICE developing budget needs, workforce plans, and performance measures for immigration-related objectives?"

Information Technology: Management Improvements Needed on the Department of Homeland Security's Next Generation Information Sharing System
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) is responsible for coordinating the federal government's homeland security communications with all levels of government. In support of this mission, DHS implemented, and has been enhancing, the Homeland Security Information Network (HSIN). It also has proposed a follow-on system, called Next Generation HSIN (HSIN Next Gen). GAO was asked to determine whether (1) DHS has stopped further improvements on HSIN and if so, the department's rationale for doing so and plans for acquiring its proposed follow-on system HSIN Next Gen and (2) the department is effectively managing the HSIN Next Gen acquisition. To accomplish this, GAO analyzed documentation, interviewed officials, and compared acquisition management processes and practices defined in industry best practices with those planned and underway by DHS."

Clean Air Act: Mercury Control Technologies at Coal-Fired Power Plants Have Achieved Substantial Emissions Reductions
A letter report issued by the Government Accountability Office with an abstract that begins "The 491 U.S. coal-fired power plants are the largest unregulated industrial source of mercury emissions nationwide, annually emitting about 48 tons of mercury--a toxic element that poses health threats, including neurological disorders in children. In 2000, the Environmental Protection Agency (EPA) determined that mercury emissions from these sources should be regulated, but the agency has not set a maximum achievable control technology (MACT) standard, as the Clean Air Act requires. Some power plants, however, must reduce mercury emissions to comply with state regulations or consent decrees. After managing a long-term mercury control research and development program, the Department of Energy (DOE) reported in 2008 that systems that inject sorbents--powdery substances to which mercury binds--into the exhaust from boilers of coal-fired power plants were ready for commercial deployment. Tests of sorbent injection systems, the most mature mercury control technology, were conducted on a variety of coal types and boiler configurations--that is, on boilers using different air pollution control devices. In this context, GAO was asked to examine (1) reductions achieved by mercury control technologies and the extent of their use at power plants, (2) the cost of …

Dialysis Facilities: Problems Remain in Ensuring Compliance with Medicare Quality Standards
A letter report issued by the General Accounting Office with an abstract that begins "Most patients with end-stage renal disease (ESRD) must rely on dialysis treatments to compensate for kidney failure. Currently, over 222,000 ESRD patients visit dialysis centers several times a week to have toxins removed from their bloodstreams. While dialysis care has improved overall, questions remain regarding the quality of care provided by some of the nation's roughly 4,000 ESRD facilities. We examined (1) the extent and nature of quality of care problems identified at dialysis facilities, (2) the effectiveness of state survey agencies in ensuring that quality issues are uncovered, corrected, and stay corrected, and (3) the extent to which the Centers for Medicare & Medicaid Services (CMS) funds, monitors, and assists state survey activities related to dialysis care."

Purchase Cards: Navy Vulnerable to Fraud and Abuse but Is Taking Action to Resolve Control Weaknesses
Testimony issued by the General Accounting Office with an abstract that begins "For a number of years, the Department of Defense (DOD) has been promoting departmentwide use of purchase cards, and their use has dramatically increased. DOD reported that in fiscal year 2001, more than 230,000 civilian and military cardholders made 10.7 million purchase card transactions valued at more than $6.1 billion. The Navy has the second largest purchase card program in DOD. As was previously reported, there were significant breakdowns in internal control at two Navy sites that left those units vulnerable to fraud, waste, and abuse. These weaknesses are representative of systematic Navy-wide purchase card control weaknesses that have left Navy vulnerable to fraudulent, wasteful, and abusive use of purchase cards. Since the original report, the Navy has been taking actions to improve the purchase card control environment and improve cardholder adherence to key purchase card control procedures. The Navy has also taken more aggressive actions to identify fraudulent, improper, and abusive or questionable purchase card acquisitions."

Defense Acquisitions: Rapid Acquisition of MRAP Vehicles
Testimony issued by the Government Accountability Office with an abstract that begins "As of July 2008, about 75 percent of casualties in combat operations in Iraq and Afghanistan were attributed to improvised explosive devices. To mitigate the threat from these weapons, the Department of Defense (DOD) initiated the Mine Resistant Ambush Protected (MRAP) program in February 2007, which used a tailored acquisition approach to rapidly acquire and field the vehicles. In May 2007, the Secretary of Defense affirmed MRAP as DOD's most important acquisition program. To date, about $22.7 billion has been appropriated for the procurement of more than 16,000 MRAP vehicles. This testimony today describes the MRAP acquisition process, the results to date, lessons learned from that acquisition, and potential implications for improving the standard acquisition process. It is mostly based on the work we have conducted over the past few years on the MRAP program. Most prominently, in 2008, we reported on the processes followed by DOD for the acquisition of MRAP vehicles and identified challenges remaining in the program. To describe DOD's approach for and progress in implementing its strategy for rapidly acquiring and fielding MRAP vehicles, we reviewed DOD's plans to buy, test, and field the …

Travel Cards: Control Weaknesses Leave Navy Vulnerable to Fraud and Abuse
Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the Department of the Navy's internal controls over the government travel card program. The Navy's average delinquency rate of 12 percent over the last 2 years is nearly identical to the Army's, which has the highest delinquency rate in the Department of Defense, and 6 percentage points higher than that of federal civilian agencies. The Navy's overall delinquency and charge-off problems, which have cost the Navy millions in lost rebates and higher fees, are primarily associated with lower-paid, enlisted military personnel. In addition, lack of management emphasis and oversight has resulted in management failure to promptly detect and address instances of potentially fraudulent and abusive activities related to the travel card program. During fiscal year 2001 and the first 6 months of fiscal year 2002, over 250 Navy personnel might have committed bank fraud by writing three or more nonsufficient fund checks to Bank of America, while many others abused the travel card program by failing to pay Bank of America charges or using the card for inappropriate transactions such as for prostitution and gambling. However, because Navy management was often not aware of these …

Catastrophe Insurance Risks: The Role of Risk-Linked Securities
Testimony issued by the General Accounting Office with an abstract that begins "Because of population growth, resulting real estate development, and rising real estate values in hazard-prone areas, our nation is increasingly exposed to higher property casualty losses--both insured and uninsured--from natural catastrophes than in the past. In the 1990s, a series of natural disasters, including Hurricane Andrew and the Northridge earthquake, raised questions about the adequacy of the insurance industry's financial capacity to cover large catastrophes without limiting coverage or raising premiums. Recognizing this greater exposure and responding to concerns about insurance market capacity, participants in the insurance industry and capital markets have developed new capital market instruments as an alternative to traditional property-casualty reinsurance, or insurance for insurers. GAO's objectives were to (1) describe catastrophe risk and how the insurance and capital markets provide coverage against such risks; (2) describe how risk-linked securities, particularly catastrophe bonds, are structured; and (3) analyze how key regulatory, accounting, tax, and investor issues might affect the use of risk-linked securities."

Fannie Mae and Freddie Mac: Analysis of Options for Revising the Housing Enterprises' Long-term Structures
Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses the results of our recently issued report on options for restructuring two government-sponsored enterprises (GSE): Fannie Mae and Freddie Mac (enterprises). On September 6, 2008, the Federal Housing Finance Agency (FHFA) placed Fannie Mae and Freddie Mac in conservatorship out of concern that their deteriorating financial condition and potential default on $5.4 trillion in financial obligations threatened the stability of financial markets. Since then, the Department of the Treasury (Treasury) has provided nearly $100 billion to the enterprises, and the Congressional Budget Office (CBO) estimated that the total cost of Treasury financial assistance will be nearly $400 billion. Moreover, the Board of Governors of the Federal Reserve System (Federal Reserve) has committed to purchasing up to $1.45 trillion in the debt and securities of the enterprises (and other entities) to support housing finance, housing markets, and financial markets. While the conservatorships can remain in place as efforts are undertaken to stabilize the enterprises and restore confidence in financial markets, FHFA said that the conservatorships were not intended to be permanent. Over the longer term, Congress and the executive branch will face difficult decisions on how …

Information Technology: Agencies Need to Improve the Implementation and Use of Earned Value Techniques to Help Manage Major System Acquisitions
A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2009, the federal government planned to spend about $71 billion on information technology (IT) investments. To more effectively manage such investments, in 2005 the Office of Management and Budget (OMB) directed agencies to implement earned value management (EVM). EVM is a project management approach that, if implemented appropriately, provides objective reports of project status, produces early warning signs of impending schedule delays and cost overruns, and provides unbiased estimates of anticipated costs at completion. GAO was asked to assess selected agencies' EVM policies, determine whether they are adequately using earned value techniques to manage key system acquisitions, and eval- uate selected investments' earned value data to determine their cost and schedule performances. To do so, GAO compared agency policies with best practices, performed case studies, and reviewed documenta- tion from eight agencies and 16 major investments with the highest levels of IT development-related spending in fiscal year 2009."

Defects in p-GaN and their atomic structure
In this paper defects formed in p-doped GaN:Mg grown with Ga polarity will be discussed. The atomic structure of these characteristic defects (Mg-rich hexagonal pyramids and truncated pyramids) in bulk and thin GaN:Mg films grown with Ga polarity was determined at atomic resolution by direct reconstruction of the scattered electron wave in a transmission electron microscope. Small cavities were present inside the defects. The inside walls of the cavities were covered by GaN which grew with reverse polarity compared to the matrix. It was proposed that lateral overgrowth of the cavities restores matrix polarity on the defect base. Exchange of Ga and N sublattices within the defect compared to the matrix lead to a 0.6 {+-} 0.2 {angstrom} displacement between the Ga sublattices of these two areas. A [1{und 1}00]/3 shift with change from AB stacking in the matrix to BC within the entire pyramid is observed

PROCEEDINGS OF RIKEN BNL RESEARCH CENTER WORKSHOP ENTITLED "GLOBAL ANALYSIS OF POLARIZED PARTON DESTRIBUTIONS IN THE RHIC ERA" (VOLUME 86).
The determination of the polarized gluon distribution is a central goal of the RHIC spin program. Recent achievements in polarization and luminosity of the proton beams in RHIC, has enabled the RHIC experiments to acquire substantial amounts of high quality data with polarized proton beams at 200 and 62.4 GeV center of mass energy, allowing a first glimpse of the polarized gluon distribution at RHIC. Short test operation at 500 GeV center of mass energy has also been successful, indicating absence of any fundamental roadblocks for measurements of polarized quark and anti-quark distributions planned at that energy in a couple of years. With this background, it has now become high time to consider how all these data sets may be employed most effectively to determine the polarized parton distributions in the nucleon, in general, and the polarized gluon distribution, in particular. A global analysis of the polarized DIS data from the past and present fixed target experiments jointly with the present and anticipated RHIC Spin data is needed.

The NOvA Technical Design Report
Technical Design Report (TDR) describes the preliminary design of the NOvA accelerator upgrades, NOvA detectors, detector halls and detector sites. Compared to the March 2006 and November 2006 NOvA Conceptual Design Reports (CDR), critical value engineering studies have been completed and the alternatives still active in the CDR have been narrowed to achieve a preliminary technical design ready for a Critical Decision 2 review. Many aspects of NOvA described this TDR are complete to a level far beyond a preliminary design. In particular, the access road to the NOvA Far Detector site in Minnesota has an advanced technical design at a level appropriate for a Critical Decision 3a review. Several components of the accelerator upgrade and new neutrino detectors also have advanced technical designs appropriate for a Critical Decision 3a review. Chapter 1 is an Executive Summary with a short description of the NOvA project. Chapter 2 describes how the Fermilab NuMI beam will provide a narrow band beam of neutrinos for NOvA. Chapter 3 gives an updated overview of the scientific basis for the NOvA experiment, focusing on the primary goal to extend the search for {nu}{sub {mu}} {yields} {nu}{sub e} oscillations and measure the sin{sup 2}(2{theta}{sub 13}) parameter. …

Amplification of an ultra short pulse laser by stimulated Raman scattering of a 1 ns pulse in a low density plasma
Experiments are described in which a 1mJ, 1ps, 1200 nm seed laser beam is amplified by interaction with an intersecting 350 J, 1ns, 1054 nm pump beam in a low density (1 x 10{sup 19}/cm{sup 3}) plasma. The transmission of the seed beam is observed to be enhanced by > {approx} 25 x when the plasma is near the resonant density for stimulated Raman scattering (SRS), compared to measured transmissions at wavelengths just below the resonant value. The amplification is observed to increase rapidly with increases in both pump intensity and plasma density.
