A letter report issued by the General Accounting Office with an abstract that begins "States provide health care coverage to about 40 million uninsured, low-income adults and children under two federal-state programs--Medicaid and the State Children's Health Insurance Program (SCHIP). To receive federal funding, states must meet statutory requirements, including providing certain levels of benefits to specified populations. Under section 1115 of the Social Security Act, the Secretary of Health and Human Services (HHS) can waive many of the statutory requirements in the case of experimental, pilot, or demonstration projects likely to promote program objectives. Since August 2001, HHS has approved four of 13 waiver proposals from states to either expand health insurance to uninsured populations or extend pharmacy coverage to low-income seniors, consistent with the new goals. Of the nine proposals still under review, five seek to expand coverage to uninsured populations, while four would provide pharmacy benefits for low-income seniors. GAO has both legal and policy concerns about the extent to which the approved waivers are consistent with the goals and fiscal integrity of Medicaid and SCHIP. The legal concern is that HHS has allowed Arizona to use unspent SCHIP funding to cover adults without children, despite SCHIP's …

A letter report issued by the General Accounting Office with an abstract that begins "The Internal Revenue Service (IRS) established critical job responsibilities for group managers and frontline employees that align with each of the agency's three strategic goals. In the group managers' performance management system, all of the supporting behaviors clearly align with the critical job responsibilities. However, for frontline employees, the supporting behaviors do not always align with IRS's description of the critical job responsibilities. Misalignments occur when (1) supporting behaviors reflect concerns not expressed in the description, (2) supporting behaviors that relate to a responsibility are located under other responsibilities, or (3) no supporting behavior exists to support the description. Raters provided feedback on the three critical job responsibilities related to IRS's organizational goals in 90 percent or more of evaluations and provided feedback on leadership and equal employment opportunity in 70 percent of the evaluations. IRS senior executives have no firm plans to monitor how well the group managers' and frontline employees' systems are being implemented or to assess whether changes need to be made, even though IRS's management processes call for obtaining data on how well programs are achieving their goals."

A letter report issued by the General Accounting Office with an abstract that begins "The National Instant Criminal Background Check System (NICS) searches state criminal history records to prevent gun sales to ineligible persons. GAO found that state firearm laws and procedures may affect how these records are used by NICS. Each of the six states GAO surveyed had some mechanism by which persons with criminal convictions could have their rights to own a firearm restored. The six states typically require a waiting period before someone can apply for relief, and some criminal convictions make a person ineligible for restoration. In 26 states, the Bureau of Alcohol, Tobacco and Firearms has determined that a concealed carry permit may exempt permit holders from an NICS background check when they are buying a firearm. This situation underscores the need to carefully screen applications and monitor permit holders to ensure their eligibility to own firearms. The six states used various approaches to make it easier to identify individuals convicted of domestic violence. Despite these efforts, NICS failed to detect more than 2,800 persons convicted of domestic violence who bought firearms during the first three years the system was in operation."

A letter report issued by the General Accounting Office with an abstract that begins "The Air Force launched an acquisition program to develop and produce a revolutionary laser weapon system, known as the Airborne Laser, in 1996. Being developed for installation in a modified Boeing 747 aircraft, it is intended to destroy enemy ballistic missiles almost immediately after their launch. The Air Force originally estimated development costs at $2.5 billion and projected fielding of the system in 2006. However, by August 2001, the Air Force determined that the development cost estimate rose 50 percent to $3.7 billion, and the fielding date slipped to 2010. The Department of Defense transferred responsibility for the Airborne Laser in October 2001 to the Ballistic Missile Defense Organization. Subsequently, the Defense Secretary designated the Ballistic Missile Defense Organization as the Missile Defense Agency and granted the agency expanded responsibility and authority. The Air Force was unable to meet the Airborne Laser's original cost and schedule goals because it did not fully understand the level of effort that would be required to develop the critical system technology needed to meet the user's requirements. The Missile Defense Agency's new strategy for developing the Airborne Laser incorporates some …

A letter report issued by the General Accounting Office with an abstract that begins "Every year investors lose money to individuals and corporations that violate federal securities laws. One mission of the Securities and Exchange Commission (SEC) is to deter such violations and return lost funds to investors. SEC's primary tool is the disgorgement order, which requires violators to give up money obtained through securities law violations. In order for disgorgement to succeed, SEC must have an effective disgorgement collection program. Although the courts have ordered billions of dollars in disgorgement in the last decade, concerns exist about SEC's success in collecting these funds. For several reasons, SEC's disgorgement collection rate is not an adequate measure of the effectiveness of SEC's disgorgement program. First, while SEC data showed a collection rate of 14 percent for the $3.1 billion in disgorgement ordered in 1995-2001--compared with the 50 percent collection rate GAO reported in its 1994 report--GAO found that the rate varied widely from year to year and was influenced by large individual disgorgement orders. Second, the data used to calculate the collection rate was not reliable because of weaknesses in entering and updating information in SEC's disgorgement tracking database. Third, factors …

A letter report issued by the General Accounting Office with an abstract that begins "The Army's approach to assessing wartime spare parts industrial base capability does not use current data from industry. Instead, the Army uses historical parts procurement data because its prior efforts to collect current data from industry were not successful due to poor response rates. GAO identified a program in the Defense Logistics Agency (DLA) that has several attributes reflecting sound management practices for reliable industrial base capability assessments. Although DLA's program is in its early stages of implementation, DLA has been able to successfully collect current data directly from private industry on thousands of parts. Further, DLA is analyzing that data to identify actual or potential parts availability problems."

The magnetoresistive properties of La0.7Ca0.3MnO3 change rapidly when Ti or Ga are substituted on the Mn site for concentrations, x, from 1 to 10 percent. The samples exhibit colossal magnetoresistance (CMR) and the resistivity increases dramatically with dopant concentration. The temperature of the resistivity peak, TR, shifts rapidly to lower temperatures with increasing x and the ferromagnetic transition broadens. However, the transition temperature, Tc, is only slightly suppressed. Consequently, TR occurs well below Tc for x above 2 percent. Investigations of these materials using Mn XAFS show that changes in the local structure, parametrized by the pair-distribution width, sigma, correlate well with Tc and the sample magnetization. For a given dopant, the resistivity peak occurs when sigma{sup 2} decreases below a critical value. Both dopants produce extended defects which increases the resistivity of the nearby materials considerably. The data suggest that even at x {approx}4 percent, most of the sites are slightly distorted at low T.

The Fermilab accelerator complex has been operating Run II for approximately one year. In this mode 36 proton bunches collide with 36 antiproton bunches at 2 interaction regions in the Tevatron at 980 GeV beam energy. The long range goal in Run II is to obtain a total integrated luminosity of 15 pb{sup -1}. The current status and performance of the accelerator complex is described, including the Tevatron, Main Injector, Antiproton Source, and Recycler Ring. Future upgrade plans and prospects for reaching the admittedly ambitious long range goal are presented.

The Pennsylvania State University, under contract to the U.S. Department of Energy (DOE), National Energy Technology Laboratory (NETL) is performing a feasibility analysis on installing a state-of-the-art circulating fluidized bed (CFB) boiler and ceramic filter emission control device at Penn State's University Park campus for cofiring multiple biofuels and other wastes with coal, and developing a test program to evaluate cofiring multiple biofuels and coal-based feedstocks. Penn State currently operates an aging stoker-fired steam plant at its University Park campus and has spent considerable resources over the last ten to fifteen years investigating boiler replacements and performing life extension studies. This effort, in combination with a variety of agricultural and other wastes generated at the agricultural-based university and the surrounding rural community, has led Penn State to assemble a team of fluidized bed and cofiring experts to assess the feasibility of installing a CFB boiler for cofiring biomass and other wastes along with coal-based fuels. The objective of the project is being accomplished using a team that includes personnel from Penn State's Energy Institute, Office of Physical Plant, and College of Agricultural Sciences; Foster Wheeler Energy Services, Inc.; Parsons Energy and Chemicals Group, Inc.; and Cofiring Alternatives.

The National Compact Stellarator Experiment (NCSX) is a stellarator-tokamak hybrid seeking to combine the good confinement, high beta and moderate aspect ratio of the tokamak with the quasi-steady-state operation and good stability properties of the stellarator. A preliminary list of measurement requirements, intended to satisfy the needs of the phased research plan, provides the basis for a full complement of plasma diagnostics. It is important to consider this full set, even at this early stage, to assess the adequacy of the stellarator design for diagnostic port access. The 3-D nature of the plasma is a measurement challenge, as is the necessity for high spatial resolution to assess the quality of magnetic surfaces. Other diagnostic requirements include the need for re-entrant views that penetrate the cryostat, for a convenient e-beam probe for field line mapping, and for a diagnostic neutral beam for active spectroscopy.

We present Run I results on hard diffraction obtained by the CDF Collaboration in proton-antiproton collisions at the Fermilab Tevatron. They are compared with results from the DESY ep collider HERA and/or theoretical predictions to test factorization in hard diffraction. In addition, the CDF program for diffractive studies in Run II is presented briefly.

The authors would like to determine |V{sub cb}| from the exclusive semi-leptonic decay B{yields}D*lv. The differential decay rate is d{Lambda}/dw = G{sub F}{sup 2}/4{pi}{sup 3}(w{sup 2}-1){sup 1/2}m{sub D*}{sup 3} (m{sub B}-m{sub D*}){sup 2}G(w)|V{sub cb}|{sup 2}|F{sub B{yields}D*}(w)|{sup 2}, where w = v {center_dot} v{prime} and G(1) = 1. At zero recoil (w = 1) heavy-quark symmetry requires F{sub B{yields}D*}(1) to be close to 1. So, |V{sub cb}| is determined by dividing measurements of d{Lambda}/dw by the phase space and well-known factors, and extrapolating to w {yields} 1. This yields |V{sub cb}|F{sub B{yields}D*}(1), and F{sub B{yields}D*}(1) is taken from ''theory''. To date models [1] or a combination of a rigorous inequality plus judgement [2] have been used to estimate F{sub B{yields}D*}(1) - 1. In this work [3] they calculate F{sub B{yields}D*}(1) with lattice gauge theory, in the so-called quenched approximation, but the uncertainty from quenching is included in the error budget.

High energy and nuclear physics experiments need tracking devices with increasing spatial precision and readout speed in the face of ever-higher track densities and increased radiation environments. The new generation of hybrid pixel detectors (arrays of silicon diodes bump bonded to arrays of front-end electronic cells) is the state of the art technology able to meet these challenges. We report on irradiation studies performed on BTeV pixel readout chip prototypes exposed to a 200 MeV proton beam at Indiana University Cyclotron Facility. Prototype pixel readout chip preFPIX2 has been developed at Fermilab for collider experiments and implemented in standard 0.25 micron CMOS technology following radiation tolerant design rules. The tests confirmed the radiation tolerance of the chip design to proton total dose up to 87 MRad. In addition, non destructive radiation-induced single event upsets have been observed in on-chip static registers and the single bit upset cross section has been extensively measured.

High performance operating regimes have been achieved on NSTX (National Spherical Torus Experiment) through impurity control and wall-conditioning techniques. These techniques include HeGDC-aided boronization using deuterated trimethylboron, inter-discharge HeGDC, 350 C PFC bake-out followed by D2 and HeGDC, and experiments to test fueling discharges with either a He-trimethylboron mixture or pure trimethylboron. The impact of this impurity and density control program on recent advances in NSTX plasma performance is discussed.

The use of flowing liquid lithium as a first wall for a reactor has potentially attractive physics and engineering features. The Current Drive experiment-Upgrade (CDX-U) at the Princeton Plasma Physics Laboratory has begun experiments with a fully toroidal liquid lithium limiter. CDX-U is a compact [R = 34 cm, a = 22 cm, Btoroidal = 2 kG, IP =100 kA, T(subscript)e(0) {approx} 100 eV, n(subscript)e(0) {approx} 5 x 10{sup 19} m-3] short-pulse (<25 msec) spherical tokamak with extensive diagnostics. The limiter, which consists of a shallow circular stainless steel tray of radius 34 cm and width 10 cm, can be filled with lithium to a depth of a few millimeters, and forms the lower limiting surface for the discharge. Heating elements beneath the tray are used to liquefy the lithium prior to the experiment. The total area of the tray is approximately 2000 cm{sup 2}. The tokamak edge plasma, when operated in contact with the lithium-filled tray, shows evidence of reduced impurities and recycling. The reduction in re cycling and impurities is largest when the lithium is liquefied by heating to 250 degrees Celsius. Discharges which are limited by the liquid lithium tray show evidence of performance enhancement. Radiated power …

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

A letter report issued by the General Accounting Office with an abstract that begins "The Unemployment Insurance (UI) program is a federal-state partnership to help replace the lost earnings of unemployed persons and to stabilize the economy during a recession. The Department of Labor estimates that $2.4 billion in overpayments were made in 2001, including $577 million attributed to fraud or abuse. Overpayments in the UI program result from management and operational practices at the state and federal level. At the state level, many states do not sufficiently balance the need to quickly process and pay UI claims with the need to control program payments. Moreover, states rely heavily on self-reported information from claimants for other important data, such as a claimant's receipt of other federal or state program benefits and whether they are citizens of the United States. At the federal level, policies and directives from the Department of Labor affect states' priorities and procedures in a manner that makes overpayments more likely."

The Tevatron hadron collider provides the unique opportunity to study Quantum Chromodynamics, QCD, at the highest energies. The results summarized in this talk, although representing different experimental objects, as hadronic jets and electromagnetic clusters, serve to determine the fundamental input ingredients of QCD as well as to search for new physics. The authors present results from QCD studies at the Tevatron from Run 1 data, including jet and direct photon production, and a measurement of the strong coupling constant.

Using a recently developed failure theory for transversely isotropic fiber composites, it is shown how the orientation of the failure surface can be determined for transverse tension and compression. Experimental data on failure surface orientations have been obtained for four carbon fiber composite systems based on both thermoplastic and thermosetting matrix materials. Average compression failure planes for the different composite materials were measured to range from 31{sup o} to 38{sup o} from the load axis. Reasonable agreement was obtained between these measured angles and those predicted from application of the new failure theory.
