Correspondence issued by the Government Accountability Office with an abstract that begins "Since the September 11, 2001 attacks on the World Trade Center and the Pentagon, the United States has launched several military operations that have dramatically increased the operations tempo of the military services and required the large-scale mobilization of reservists. These factors have particularly affected the active Army, Army Reserve, and Army National Guard, which have shouldered the bulk of the personnel burden associated with ongoing operations in Iraq. A 2007 Congressional Research Service report notes that many observers have expressed concern that these factors might lead to lower recruiting and retention rates, thereby jeopardizing the vitality of today's all-volunteer military. Additionally, in 2004 the Army began its modular force transformation to restructure itself from a division-based force to a more agile and responsive modular brigade-based force--an undertaking it considers to be the most extensive reorganization of its force since World War II. Both ongoing military operations and transformation have prompted the Army to increase its recruitment efforts. To encourage military service, Congress, through Section 681 of the National Defense Authorization Act for Fiscal Year 2006, temporarily authorized the Army to provide not more than four new recruitment …

Correspondence issued by the Government Accountability Office with an abstract that begins "As part of its mission to protect human health and the environment, the Environmental Protection Agency's (EPA) enforcement office maintains civil and criminal enforcement programs to help enforce the requirements of major federal environmental laws such as the Clean Air Act and the Clean Water Act. EPA's civil and criminal enforcement programs work with the Department of Justice (DOJ), and in some cases states, to take legal actions to bring polluters into compliance with federal laws. While civil enforcement actions require polluters to pay penalties and take other corrective actions, criminal enforcement actions also may include imprisonment. EPA's enforcement office sets national priorities to focus resources on significant environmental risks and non-compliance patterns; prepares nationally significant civil and criminal cases for legal action by DOJ; uses 10 regional offices to implement civil enforcement actions on a day-to-day basis; and pursues criminal violations of environmental laws through its criminal enforcement office. The agency exercises its authority to independently pursue some violators through administrative proceedings--civil administrative actions--and to refer significant matters to DOJ when it believes cases need to be filed in federal court as civil judicial actions. DOJ is …

A letter report issued by the Government Accountability Office with an abstract that begins "Voluntary organizations have traditionally played a major role in the nation's response to disasters, but the response to Hurricane Katrina raised concerns about their ability to handle large-scale disasters. This report examines (1) the roles of five voluntary organizations in providing mass care and other services, (2) the steps they have taken to improve service delivery, (3) their current capabilities for responding to mass care needs, and (4) the challenges they face in preparing for large-scale disasters. To address these questions, GAO reviewed the American Red Cross, The Salvation Army, the Southern Baptist Convention, Catholic Charities USA, and United Way of America; interviewed officials from these organizations and the Federal Emergency Management Agency (FEMA); reviewed data and laws; and visited four high-risk metro areas--Los Angeles, Miami, New York, and Washington, D.C."

A letter report issued by the Government Accountability Office with an abstract that begins "The United States is the largest financial contributor to United Nations (UN) peacekeeping operations--providing about $1.4 billion in 2008 (about 26 percent of the total UN peacekeeping assessed budget)--and has a strong interest in the efficient and effective management of these operations. The size and scope of UN peacekeeping has significantly increased over the past several years and the UN has pursued management reforms to strengthen its capacity to support operations. GAO was asked to examine (1) the status of the current restructuring and strengthening of peacekeeping management including procurement for the field, (2) the status of reforms to address previously identified problems with peacekeeping procurement, and (3) the UN Logistics Base's support of peacekeeping operations. GAO reviewed relevant UN documents; conducted structured interviews with chief procurement officers at 20 peacekeeping missions; and interviewed UN and U.S. officials. State agreed with the report and commented that it would draw upon some of the report findings in its discussion with the United Nations. The UN agreed with GAO's assessment of the status of reforms and provided technical comments, which are addressed in the report as appropriate."

Correspondence issued by the Government Accountability Office with an abstract that begins "In July 2006, the former Commander of North American Aerospace Defense Command (NORAD) and United States Northern Command (USNORTHCOM) announced plans to relocate certain functions from Cheyenne Mountain to create an integrated command center in Building 2 at Peterson Air Force Base (AFB), Colorado. In May 2007, we reported that NORAD and USNORTHCOM had not analyzed the anticipated operational effects--both positive and negative--of the relocation, and that the Department of Defense (DOD) could not discern the full costs or security implications of the move until ongoing security assessments had been completed and a protection level designated for the integrated command center. We suggested that Congress should consider restricting DOD's authority to fund the relocation until all security analyses were complete, the full costs for the move were determined, and DOD provided Congress with an analysis of the operational effects of the proposed realignments. As a result, in the National Defense Authorization Act for Fiscal Year 2008 (hereinafter referred to as the Act), Congress directed the Secretary of Defense to submit a report by March 1, 2008, assessing the relocation of the NORAD Command Center and related functions from …

A letter report issued by the Government Accountability Office with an abstract that begins "The Small Business Administration (SBA) and the Rural Development offices of the U.S. Department of Agriculture both work in rural areas to foster economic development by promoting entrepreneurship and community development. This report discusses (1) the complementary nature of some SBA and Rural Development programs and the extent to which it provides a rationale for the agencies to collaborate, (2) past and current efforts by SBA and Rural Development to work together and with other agencies, and (3) opportunities for the agencies to improve their collaborative efforts. In completing its work, GAO analyzed agency documentation and prior reports on collaboration, conducted site visits at locations where SBA and Rural Development were working together, and interviewed agency and selected economic development officials."

Testimony issued by the Government Accountability Office with an abstract that begins "American Samoa is the only populated U.S. insular area that does not have a federal court. Congress has granted the local High Court federal jurisdiction for certain federal matters, such as specific areas of maritime law. GAO was asked to conduct a study of American Samoa's system for addressing matters of federal law. This testimony discusses: (1) the current system for adjudicating matters of federal law in American Samoa and how it compares to those in the Commonwealth of the Northern Mariana Islands (CNMI), Guam, and the U.S. Virgin Islands (USVI); (2) the reasons offered for or against changing the current system for adjudicating matters of federal law in American Samoa; (3) potential scenarios and issues associated with establishing a federal court in American Samoa or expanding the federal jurisdiction of the local court; and (4) the potential cost elements and funding sources associated with implementing those different scenarios. This testimony is based on GAO work performed from April 2007 to June 2008."

Testimony issued by the Government Accountability Office with an abstract that begins "The Department of Veterans Affairs' (VA) disability claims process has long been a subject of concern because of long waits for decisions and large backlogs of claims pending decisions. To address these issues, VA has hired almost 3,000 new claims processors since January 2007. However, adequate training and performance management are essential to developing highly competent disability claims processors and ensuring that experienced staff maintain the skills needed to issue timely, accurate, and consistent decisions. The Subcommittee on Disability Assistance and Memorial Affairs, House Veterans' Affairs Committee asked GAO to present its views on 1) VA's training for its claims processors and 2) VA's performance management of this staff. This statement is based on a May 2008 report on VA's training and performance management (GAO-08-561) and has been updated as appropriate."

Testimony 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. Toxicity assessments in the IRIS database constitute the first two critical steps of the risk assessment process, which in turn, provides the foundation for risk management decisions. Thus, IRIS is a critical component of EPA's capacity to support scientifically sound environmental decisions, policies, and regulations. This testimony discusses (1) highlights of GAO's March 2008 report, Chemical Assessments: Low Productivity and New Interagency Review Process Limit the Usefulness and Credibility of EPA's Integrated Risk Information System; (2) key aspects of EPA's revised IRIS assessment process, released on April 10, 2008; and (3) progress EPA has made in completing assessments in fiscal year 2008. For the March 2008 report, GAO reviewed and analyzed EPA data and interviewed officials at relevant agencies, including the Office of Management and Budget (OMB). For this testimony, GAO supplemented the prior audit work with a review of EPA's revised IRIS assessment process announced on April 10, 2008. We also updated our information on EPA's assessment productivity through September …

A beam of tagged 14 MeV neutrons from the deuterium-tritium (DT) reaction is used to induce fission in a target composed of depleted uranium. The generator yield is 107 neutrons/second radiated into a 4π solid angle. Two 4 in.×4 in. NaI detectors are used for gamma-ray detection. The fission process is known to produce multiple gamma-rays and neutrons. Triple coincidences (α-γ-γ) are measured as a function of neutron flight time up to 90 ns after fission, where the α-particle arises from the DT reaction. A sudden increase in the triple coincidence rate at the location of the material is used to localize and detect fission in the interrogated target. Comparisons are made with experiment runs where lead, tungsten, and iron were used as target materials. The triple coincidence response profile from depleted uranium is noted to be different to those observed from the other target materials. The response from interrogation targets composed of fissile material is anticipated to be even more unique than that observed from depleted uranium.

This report presents data on the 140 existing and 74 planned ethanol production facilities and their proximity to candidate deep geologic storage formations. Half of the existing ethanol plants and 64% of the planned units sit directly atop a candidate geologic storage reservoir. While 70% of the existing and 97% of the planned units are within 100 miles of at least one candidate deep geologic storage reservoir. As a percent of the total CO2 emissions from these facilities, 92% of the exiting units CO2 and 97% of the planned units CO2 emissions are accounted for by facilities that are within 100 miles of at least one potential CO2 storage reservoir.

The RF source High Voltage Converter Modulator (HVCM) systems installed on the Spallation Neutron Source (SNS) have operated well in excess of 200,000 hours, during which time numerous failures have occurred. An improved Insulated Gate Bipolar Transistor (IGBT) switch plate is under development to help mitigate these failures. The new design incorporates two significant improvements. The IGBTs are upgraded to 4500 V, 1200 A, press-pack devices, which increase the voltage margin, facilitate better cooling, and eliminate explosive disassembly of the package in the event of device failure. The upgrade to an advanced IGBT gate drive circuit decreases switching losses and improves fault-condition response. The upgrade design and development status will be presented.

The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) is coming on-line to support physics experimentation for the U.S. Department of Energy (DOE) programs in Inertial Confinement Fusion (ICF) and Stockpile Stewardship (SS). Optical streak cameras are an integral part of the experimental diagnostics instrumentation at NIF. To accurately reduce streak camera data a highly accurate temporal calibration is required. This article describes a technique for simultaneously generating a precise +/- 2 ps optical marker pulse (fiducial reference) and trains of precisely timed, short-duration optical pulses (so-called “comb” pulse trains) that are suitable for the timing calibrations. These optical pulse generators are used with the LLNL optical streak cameras. They are small, portable light sources that, in the comb mode, produce a series of temporally short, uniformly spaced optical pulses, using a laser diode source. Comb generators have been produced with pulse-train repetition rates up to 10 GHz at 780 nm, and somewhat lower frequencies at 664 nm. Individual pulses can be as short as 25-ps FWHM. Signal output is via a fiber-optic connector on the front panel of the generator box. The optical signal is transported from comb generator to streak camera through multi-mode, graded-index optical fiber.

We have demonstrated the ability to measure the neutron flux produced by the cosmic-ray interaction with nuclei in the ground surface using aerial neutron detection. High energy cosmic-rays (primarily muons with GeV energies) interact with the nuclei in the ground surface and produce energetic neutrons via spallation. At the air-surface interface, the neutrons produced by spallation will either scatter within the surface material, become thermalized and reabsorbed, or be emitted into the air. The mean free path of energetic neutrons in air can be hundreds of feet as opposed to a few feet in dense materials. As such, the flux of neutrons escaping into the air provides a measure of the surface nuclei composition. It has been demonstrated that this effect can be measured at long range using neutron detectors on low flying helicopters. Radiological survey measurements conducted at Government Wash in Las Vegas, Nevada, have shown that the neutron background from the cosmic-soil interactions is repeatable and directly correlated to the geological data. Government Wash has a very unique geology, spanning a wide variety of nuclide mixtures and formations. The results of the preliminary measurements are presented.

The SEMATECH Berkeley Actinic Inspection Tool (AIT) is an EUV-wavelength mask inspection microscope designed for direct aerial image measurements, and pre-commercial EUV mask research. Operating on a synchrotron bending magnet beamline, the AIT uses an off-axis Fresnel zoneplate lens to project a high-magnification EUV image directly onto a CCD camera. We present the results of recent system upgrades that have improved the imaging resolution, illumination uniformity, and partial coherence. Benchmarking tests show image contrast above 75% for 100-nm mask features, and significant improvements and across the full range of measured sizes. The zoneplate lens has been replaced by an array of user-selectable zoneplates with higher magnification and NA values up to 0.0875, emulating the spatial resolution of a 0.35-NA 4 x EUV stepper. Illumination uniformity is above 90% for mask areas 2-{micro}m-wide and smaller. An angle-scanning mirror reduces the high coherence of the synchrotron beamline light source giving measured {sigma} values of approximately 0.125 at 0.0875 NA.

The beam diagnostics in the linac for the Linac Coherent Light Source (LCLS) X-ray FEL project at SLAC includes optical transition radiation (OTR) screens for measurements of transverse and longitudinal beam properties. We report on observations of coherent light emission from the OTR screens (COTR) at visible wavelengths from the uncompressed and compressed electron beam at various stages in the accelerator.

Type IV waste tanks were designed and built to store waste that does not require auxiliary cooling. Each Type IV tank is a single-shell tank constructed of a steel-lined pre-stressed concrete tank in the form of a vertical cylinder with a concrete domed roof. There are four such tanks in F-area, Tanks 17-20F, and four in H-Area, Tanks 21-24H. Leak sites were discovered in the liners for Tanks 19 and 20F in the 1980's. Although these leaks were visually observed, the investigation to determine the mechanism by which the leaks had occurred was not completed at that time. Therefore, a concern was raised that the same mechanism which caused the leak sites in the Tanks in F-area may also be operable in the H-Area tanks. Data from the construction of the tanks (i.e., certified mill test reports for the steel, no stress-relief), the service history (i.e., waste sample data, temperature data), laboratory tests on actual wastes and simulants (i.e., electrochemical testing), and the results of the visual inspections were reviewed. The following observations and conclusions were made: (1) Comparison of the compositional and microstructural features indicate that the A212 material utilized for construction of the H-Area tanks are far more …

The authors report a Dalitz-plot analysis of the charmless hadronic decays of neutral B mesons to K{sup {+-}}{pi}{sup {-+}}{pi}{sup 0}. With a sample of (231.8 {+-} 2.6) x 10{sup 6}{Upsilon}(4S) {yields} B{bar B} decays collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC, they measure the magnitudes and phases of the intermediate resonant and nonresonant amplitudes for B{sup 0} and {bar B}{sup 0} decays and determine the corresponding CP-averaged branching fractions and charge asymmetries. The inclusive branching fraction and CP-violating charge asymmetry are measured to be {Beta}(B{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0}) = (35.7{sub -1.5}{sup +2.6} {+-} 2.2) x 10{sup -6}, and {Alpha}{sub CP} = -0.030{sub -0.051}{sup +0.045} {+-} 0.055 where the first errors are statistical and the second systematic. They observe the decay B{sup 0} {yields} K*{sup 0}(892){pi}{sup 0} with the branching fraction {Beta}(B{sup 0} {yields} K*{sup 0}(892){pi}{sup 0}) = (3.6{sub -0.8}{sup +0.7} {+-} 0.4) x 10{sup -6}. This measurement differs from zero by 5.6 standard deviations (including the systematic uncertainties). The selected sample also contains B{sup 0} {yields} {bar D}{sup 0}{pi}{sup 0} decays where {bar D}{sup 0} {yields} K{sup +}{pi}{sup -}, and they measure {Beta}(B{sup 0} {yields} {bar D}{sup 0}{pi}{sup 0}) = (2.93 …

Quantitative knowledge of the magnitude, extent and trends of the Digital Divide are critical to understand and identify the regions most in need of help, to make rational decisions on how to address the problems and to make cases for executives, funding agencies and politicians. We report on a project (PingER) to measure the Digital Divide from the point of view of Internet performance. The PingER project has been measuring Internet performance since 1995 and with the increased emphasis on measuring and tracking the Digital Divide, it now covers over 700 hosts in over 150 countries that between them contain over 99% of the world's Internet connected population. In this paper we will describe the how PingER works, it deployment, the data analysis, and presentation. We also introduce a new PingER visualization tool (ViPER) that provides a more appealing interactive visualization of the PingER data and also works on mobile PDAs. We will also show results from PingER that illustrate the magnitude, extent and trends for the Digital Divide, and also compare PingER results with some human development and technology indices.
