Medicaid Drug Rebate Program: Inadequate Oversight Raises Concerns about Rebates Paid to States
A letter report issued by the Government Accountability Office with an abstract that begins "To help control Medicaid spending on drugs, states receive rebates from pharmaceutical manufacturers through the Medicaid drug rebate program. Rebates are based on two prices--best price and average manufacturer price (AMP)--reported by manufacturers. Both reflect manufacturers' prices to various entities, accounting for certain financial concessions like discounts. Concerns have been raised about rising Medicaid drug spending. GAO studied (1) federal oversight of manufacturer-reported best prices and AMPs and the methods used to determine them, (2) how manufacturers' determinations of those prices could have affected rebates, and (3) how the rebate program reflects financial concessions in the private market."

Telecommunications: Wire-Based Competition Benefited Consumers In Selected Markets
A letter report issued by the General Accounting Office with an abstract that begins "One of the primary purposes of the Telecommunications Act of 1996 was to promote competition in telecommunication markets, but wire-based competition has not developed as fully as expected. However, a new kind of entrant, called broadband service providers (BSP), offers an alternative wire- based option for local telephone, subscription television, and high- speed Internet services to consumers in the markets they have chosen to enter. This report provides information on (1) BSPs' business strategy, (2) the impact of BSPs' market entry on incumbent companies' behavior and consumer prices for telecommunications services, (3) the key factors that BSPs consider when making decisions about which local markets to enter, and (4) the success of BSPs in attaining subscribership and any key factors that may limit their success. We developed a case-study approach to compare 6 cities where a BSP has been operating for at least 1 year with 6 similar cities that do not have such a competitor. The 6 markets with a BSP presently account for more than 20 percent of the households nationwide that are in areas where BSPs currently offer the three-service package, but the …

Social Security Disability: Disappointing Results from SSA's Efforts to Improve the Disability Claims Process Warrant Immediate Attention
A letter report issued by the General Accounting Office with an abstract that begins "The number of people applying for benefits from the Social Security Administration's (SSA) two disability programs grew dramatically during the 1990s. As a result, the Disability Insurance and Supplemental Security Programs began to experience huge backlogs of undecided claims. SSA has spent $39 million during the past seven years on various initiatives to help it better manage its caseloads and ensure high-quality service. SSA spent another $71 million to develop an automated disability claims process. This report reviews the status and outcomes of five initiatives intended to improve SSA's disability claims process. GAO found that the results of the initiatives have been disappointing."

Telecommunications: Federal and State Universal Service Programs and Challenges to Funding
A letter report issued by the General Accounting Office with an abstract that begins ""Universal service" means providing residential customers with affordable, nationwide access to basic phone service. The Telecommunications Act of 1996 extended support for universal service to eligible schools, libraries, and rural health care providers. Universal service programs are generally funded by mandatory contributions from telecommunications companies. New technologies, however, are putting this funding source in jeopardy. The Federal Communications Commission (FCC) has issued many orders designed to implement the act's universal service reforms. The Universal Service Administration Company runs the day-to-day operations of federal universal service programs on FCC's behalf, although FCC retains responsibility for oversight and ensuring compliance with its rules. At the state level, public utility commissions generally regulate rates for local and long-distance phone service and implement universal service programs. Public utility commissions subsidize local phone service from the rates set for urban and business phone service and for "vertical" services, such as caller ID and call waiting. Although the use of digital technologies and internet protocol networks for communications has risen rapidly during the past decade, the providers of these services are not required to contribute to the universal service fund. As these …

Social Security: Better Coordination among Federal Agencies Could Reduce Unidentified Earnings Reports
A letter report issued by the Government Accountability Office with an abstract that begins "Each year, the Social Security Administration (SSA) receives millions of employer-submitted earnings reports (Form W-2s) that it is unable to place in an individual Social Security record. If the Social Security number (SSN) and name on a W-2 do not match SSA's records, the W-2 is retained in the Earnings Suspense File (ESF). SSA's ability to match earnings reports is essential to calculating Social Security benefits. Because of concerns about the size of the ESF, GAO was asked to determine (1) how SSA processes workers' earnings reports, (2) the types of errors in ESF reports and the characteristics of employers whose reports are in the ESF, (3) how often earnings from repeatedly used SSNs have been reinstated and who receives the earnings from theses reports, and (4) what key factors contribute to ESF postings."

Veterinarian Workforce: Actions Are Needed to Ensure Sufficient Capacity for Protecting Public and Animal Health
A letter report issued by the Government Accountability Office with an abstract that begins "Veterinarians are essential for controlling zoonotic diseases--which spread between animals and humans--such as avian influenza. Most federal veterinarians work in the Departments of Agriculture (USDA), Defense (DOD), and Health and Human Services (HHS). However, there is a growing national shortage of veterinarians. GAO determined the extent to which (1) the federal government has assessed the sufficiency of its veterinarian workforce for routine activities, (2) the federal government has identified the veterinarian workforce needed during a catastrophic event, and (3) federal and state agencies encountered veterinarian workforce challenges during four recent zoonotic outbreaks. GAO surveyed 24 federal entities about their veterinarian workforce; analyzed agency workforce, pandemic, and other plans; and interviewed federal and state officials that responded to four recent zoonotic outbreaks."

Ferromagnetism in GaN: Gd: A density functional theory study
First principle calculations of the electronic structure and magnetic interaction of GaN:Gd have been performed within the Generalized Gradient Approximation (GGA) of the density functional theory (DFT) with the on-site Coulomb energy U taken into account (also referred to as GGA+U). The ferromagnetic p-d coupling is found to be over two orders of magnitude larger than the s-d exchange coupling. The experimental colossal magnetic moments and room temperature ferromagnetism in GaN:Gd reported recently are explained by the interaction of Gd 4f spins via p-d coupling involving holes introduced by intrinsic defects such as Ga vacancies.

Status of the Fast Focusing DIRC (fDIRC)
We have built and successfully tested a novel particle identification detector concept, the Fast Focusing DIRC (fDIRC). The prototype's concept is based on the BaBar DIRC with several important improvements: (a) much faster pixelated photon detectors based on Burle MCP-PMTs and Hamamatsu MaPMTs, (b) a focusing mirror allowing a smaller photon detector, reducing the sensitivity to backgrounds in future applications, (c) electronics capable of measuring the single photon resolution to better than {sigma} {approx} 100-200ps. The fDIRC is the first RICH detector to successfully correct the chromatic error by timing.

Ultrafast high strain rate acoustic wave measurements at high static pressure in a diamond anvil cell
We have used sub-picosecond laser pulses to launch ultra-high strain rate ({approx} 10{sup 9} s{sup -1}) nonlinear acoustic waves into a 4:1 methanol-ethanol pressure medium which has been precompressed in a standard diamond anvil cell. Using ultrafast interferometry, we have characterized acoustic wave propagation into the pressure medium at static compression up to 24 GPa. We find that the velocity is dependent on the incident laser fluence, demonstrating a nonlinear acoustic response which may result in shock wave behavior. We compare our results with low strain, low strain-rate acoustic data. This technique provides controlled access to regions of thermodynamic phase space that are otherwise difficult to obtain.

Parallel 3D Finite Element Numerical Modelling of DC Electron Guns
In this paper we present Gun3P, a parallel 3D finite element application that the Advanced Computations Department at the Stanford Linear Accelerator Center is developing for the analysis of beam formation in DC guns and beam transport in klystrons. Gun3P is targeted specially to complex geometries that cannot be described by 2D models and cannot be easily handled by finite difference discretizations. Its parallel capability allows simulations with more accuracy and less processing time than packages currently available. We present simulation results for the L-band Sheet Beam Klystron DC gun, in which case Gun3P is able to reduce simulation time from days to some hours.

AdS/CFT and Light-Front QCD
The AdS/CFT correspondence between string theory in AdS space and conformal field theories in physical space-time leads to an analytic, semi-classical model for strongly-coupled QCD which has scale invariance and dimensional counting at short distances and color confinement at large distances. The AdS/CFT correspondence also provides insights into the inherently nonperturbative aspects of QCD such as the orbital and radial spectra of hadrons and the form of hadronic wavefunctions. In particular, we show that there is an exact correspondence between the fifth-dimensional coordinate of AdS space z and a specific impact variable {zeta} which measures the separation of the quark and gluonic constituents within the hadron in ordinary space-time. This connection leads to AdS/CFT predictions for the analytic form of the frame-independent light-front wavefunctions (LFWFs) of mesons and baryons, the fundamental entities which encode hadron properties. The LFWFs in turn predict decay constants and spin correlations, as well as dynamical quantities such as form factors, structure functions, generalized parton distributions, and exclusive scattering amplitudes. Relativistic light-front equations in ordinary space-time are found which reproduce the results obtained using the fifth-dimensional theory and have remarkable algebraic structures and integrability properties. As specific examples we describe the behavior of the pion form …

Configuration Studies and Recommendations for the ILC Damping Rings
We describe the results of studies comparing differentoptions for the baseline configuration of the ILC damping rings. Theprincipal configuration decisions apply to the circumference, beamenergy, lattice type, and technology options for key components,including the injection/extraction kickers and the damping wigglers. Toarrive at our recommended configuration, we performed detailed studies ofa range of lattices representing a variety of different configurationoptions; these lattices are described in Chapter 2. The results of thevarious studies are reported in chapters covering issues of beamdynamics, technical subsystems, costs, and commissioning, reliability andupgradeability. Our detailed recommendations for the baselineconfiguration are given in Chapter 7, where we also outline furtherresearch and development that is needed before a machine using ourrecommended configuration can be built and operated successfully. In thesame chapter, we suggest possible alternatives to the baselineconfiguration.
