Testimony issued by the Government Accountability Office with an abstract that begins "Air ambulance transport is widely regarded as improving the chances of survival for trauma victims and other critical patients. However, recent increases in the number of air ambulance accidents have led to greater industry scrutiny by government agencies, the public, the media, and the industry itself. The National Transportation Safety Board (NTSB) and others have called on the Federal Aviation Administration (FAA), which provides safety oversight, to issue more stringent safety requirements for the industry. This testimony discusses (1) recent trends in the air ambulance industry with regard to its size, composition, and safety record; (2) recent industry and government efforts to improve air ambulance safety; and (3) potential strategies for improving air ambulance safety. This testimony is based primarily on GAO's February 2007 study on air ambulance safety (GAO-07-353). To update and supplement this 2007 report, GAO analyzed the latest safety information from NTSB and FAA, reviewed published literature on the state of the air ambulance industry, and interviewed FAA officials and industry representatives. GAO provided a copy of the draft testimony statement to FAA. FAA provided technical comments, which GAO incorporated as appropriate."

CKM mixing between third family quarks and a possible fourth family is constrained by global fits to the precision electroweak data. The dominant constraint is from nondecoupling oblique corrections rather than the vertex correction to Z {yields} {bar b}b used in previous analyses. The possibility of large mixing suggested by some recent analyses of FCNC processes is excluded, but 3-4 mixing of the same order as the Cabbibo mixing of the first two families is allowed.

Testimony issued by the Government Accountability Office with an abstract that begins "The Deepwater Program is intended to recapitalize the Coast Guard's fleet and includes efforts to build or modernize five classes each of ships and aircraft, and procure other key capabilities. In 2002, the Coast Guard contracted with Integrated Coast Guard Systems (ICGS) to manage the acquisition as systems integrator. After the program experienced a series of failures, the Coast Guard announced in April 2007 that it would take over the lead role, with future work on individual assets to be potentially bid competitively outside of the existing contract. A program baseline of $24.2 billion was set as well. In June 2008, GAO reported on the new approach and concluded that while these steps were beneficial, continued oversight and improvement was necessary. The Coast Guard has taken actions to address the recommendations in that report. This testimony updates key issues from prior work: (1) Coast Guard program management at the overall Deepwater Program and asset levels; (2) how cost, schedules, and capabilities have changed from the 2007 baseline and how well costs are communicated to Congress; and (3) Coast Guard efforts to manage and build its acquisition workforce. GAO …

This report discusses the National Water Research and Development initiative Act of 2009, that would formally establish a federal inter agency committee to coordinate federal water research. It also discusses water research coordination and strategy.

Partial ytterbium f-orbital occupancy (i.e., intermediate valence) and open-shell singlet formation are established for a variety of bipyridine and diazabutadiene adducts with decamethylytterbocene, (C5Me5)2Yb, abbreviated as Cp*2Yb. Data used to support this claim include ytterbium valence measurements using Yb LIII-edge X-ray absorption near-edge structure spectroscopy, magnetic susceptibility, and complete active space self-consistent field (CASSCF) multiconfigurational calculations, as well as structural measurements compared to density functional theory calculations. The CASSCF calculations indicate that the intermediate valence is the result of a multiconfigurational ground-state wave function that has both an open-shell singlet f13(?*)1, where pi* is the lowest unoccupied molecular orbital of the bipyridine or dpiazabutadiene ligands, and a closed-shell singlet f14 component. A number of other competing theories for the unusual magnetism in these materials are ruled out by the lack of temperature dependence of the measured intermediate valence. These results have implications for understanding chemical bonding not only in organolanthanide complexes but also for f-element chemistry in general, as well as understanding magnetic interactions in nanoparticles and devices.

Design of Experiments (DoE) were developed and performed in an effort to discover and resolve the causes of three different manufacturing issues; large panel voids after Hot Air Solder Leveling (HASL), cable hole locations out of tolerance after lamination and delamination/solder wicking around flat flex cable circuit lands after HASL. Results from a first DoE indicated large panel voids could be eliminated by removing the pre-HASL cleaning. It also revealed eliminating the pre-HASL bake would not be detrimental when using a hard press pad lamination stackup. A second DoE indicated a reduction in hard press pad stackup lamination pressure reduced panel stretch in the y axis approximately 70%. A third DoE illustrated increasing the pre-HASL bake temperature could reduce delamination/solder wicking when using a soft press pad lamination stackup.

A young person's detachment from both the labor market and school is an indicator that he or she may not be adequately making the transition to adulthood. Referred to as "disconnected" in the social science literature, youth who are not working or in school may have difficulty gaining the skills and knowledge needed to attain self-sufficiency. The purpose of the report is to provide context for Congress about the characteristics of youth who are not working or in school, and the circumstances in which they live.

Correspondence issued by the Government Accountability Office with an abstract that begins "In 2008, the Consumer Product Safety Commission (CPSC) announced that it had obtained the voluntary recall of 563 unsafe or potentially unsafe products by the companies that manufactured, imported, distributed, or sold the products--the largest number for the agency in the past 10 years. In the prior year, CPSC announced 472 recalls--which was also an increase from the previous year and included some high-profile recalls of lead-tainted toys--leading some consumer groups to call 2007 the "year of the recall." Consumer products can be recalled for a variety of reasons, including violations of safety standards, incidents of injuries that can occur from the design or manufacture of a product, or other conditions that present an imminent or substantial hazard to consumers. Since 1979 there have been few instances in which CPSC could not obtain cooperation from manufacturers or importers to conduct recalls, either because these companies did not have the financial resources to conduct a recall or because the companies refused to assume responsibility for a recall. This included troubled recalls involving more than 1.5 million imported cribs associated with multiple deaths of children. Another recall of imported tires, …

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses GAO's recently issued report on the North American Aerospace Defense Command's (NORAD) and the Department of Defense's (DOD) air sovereignty alert (ASA) operations. According to the National Strategy for Aviation Security, issued in March 2007, and officials from U.S. intelligence agencies with whom we met, air attacks are still a threat to the United States and its people. To address this threat, NORAD and DOD have fully fueled, fully armed aircraft and trained personnel on alert 24 hours a day, 365 days a year, at 18 ASA sites across the United States. Of the 18 sites, 16 are maintained by Air National Guard (ANG) units and 2 are maintained by active duty Air Force units. If warranted, NORAD can increase personnel, aircraft, and the number of ASA sites based on changes in threat conditions. The Air Force provides NORAD with personnel and equipment, including F-15 and F-16 aircraft, for these operations. ASA units are tasked to conduct and train for both expeditionary missions (e.g., military operations in Iraq) and ASA operations. This testimony will discuss whether (1) NORAD routinely conducts risk assessments to determine the …

Testimony issued by the Government Accountability Office with an abstract that begins "In 2001, GAO identified human capital management as a governmentwide high-risk area because federal agencies lacked a strategic approach to human capital management that integrated human capital efforts with their missions and program goals. Progress has been made. However, the area remains high-risk because of a continuing need for a governmentwide framework to advance human capital reform. The importance of a top-notch federal workforce cannot be overstated. The federal government is facing new and growing challenges coupled with a retirement wave and the loss of leadership and institutional knowledge at all levels. The issues facing agencies are complex and require a broad range of technical skills that are also highly sought after by the private sector. This testimony, based on a large body of completed work issued from January 2001 through March 2009, focuses on executive branch agencies' and the Office of Personnel Management's (OPM) progress in addressing strategic human capital management challenges in four key areas: (1) leadership; (2) strategic human capital planning; (3) acquiring, developing, and retaining talent; and (4) results-oriented organizational culture. In prior reports, GAO has made a range of recommendations to OPM and …

Tokamaks are sensitive to deviations from axisymmetry as small as δB=B0 ~ 10-4. These non-axisymmetric perturbations greatly modify plasma confinement and performance by either destroying magnetic surfaces with subsequent locking or deforming magnetic surfaces with associated non-ambipolar transport. The Ideal Perturbed Equilibrium Code (IPEC) calculates ideal perturbed equilibria and provides important basis for understanding the sensitivity of tokamak plasmas to perturbations. IPEC calculations indicate that the ideal plasma response, or equiva- lently the effect by ideally perturbed plasma currents, is essential to explain locking experiments on National Spherical Torus eXperiment (NSTX) and DIII-D. The ideal plasma response is also important for Neoclassical Toroidal Viscosity (NTV) in non-ambipolar transport. The consistency between NTV theory and magnetic braking experiments on NSTX and DIII-D can be improved when the variation in the field strength in IPEC is coupled with generalized NTV theory. These plasma response effects will be compared with the previous vacuum superpositions to illustrate the importance. However, plasma response based on ideal perturbed equilibria is still not suffciently accurate to predict the details of NTV transport, and can be inconsistent when currents associated with a toroidal torque become comparable to ideal perturbed currents.

Testimony issued by the Government Accountability Office with an abstract that begins "GAO's work over the past several years has demonstrated that improper payments are a long-standing, widespread, and significant problem in the federal government. The Improper Payments Information Act of 2002 (IPIA) has increased visibility over improper payments by requiring executive branch agency heads, using guidance from the Office of Management and Budget, to identify programs and activities susceptible to significant improper payments, estimate amounts improperly paid, and report on the amounts of improper payments and their actions to reduce them. This testimony addresses (1) progress made in agencies' implementation of IPIA for fiscal year 2008, and (2) several major challenges that continue to hinder full reporting of IPIA information. GAO was also asked to provide an overview of Medicare and Medicaid programs' implementation of IPIA. This testimony is based primarily on GAO products, Office of Inspector General (OIG) audit reports, and agencies' fiscal year 2008 reported improper payment information, including information reported by the Department of Health and Human Service's (HHS) Centers for Medicare and Medicaid Services (CMS). GAO also analyzed fiscal year 2008 governmentwide improper payment information to identify trends and reviewed Medicare and Medicaid programs' reported …

This report discusses Iraq's political system, which has been restructured through a U.S.-supported election process. The Iraqi government is increasingly characterized by peaceful competition rather than violence, but sectarianism and ethnic and factional infighting still remain. This report discusses issues relating to opponents of the Iraqi Prime Minister Nuri al-Maliki and also discusses the atmosphere of nationwide provincial elections.

The CeTIn_5 superconductors (T=Co, Rh, or Ir) have generated great interest due to their relatively high transition temperatures, non-Fermi liquid behavior, and their proximity to antiferromagnetic order and quantum critical points. In contrast to small changes with the T-species, electron doping in CeT(In_1-x M_x)_5 with $M$=Sn and hole doping with Cd or Hg have a dramatic effect on the electronic properties at very low concentrations. The present work reports local structure measurements usingthe extended x-ray absorption fine-structure (EXAFS) technique that address the substituent atom distribution as a function of T, M, and x, in the vicinity of the superconducting phase. Together with previous measurements for M=Sn, the proportion of the $M$ atom residing on the In(1) site, f_\textrm In(1), increases in the order M=Cd, Sn, and Hg, ranging from about 40\percent to 70percent, showing a strong preference for each of these substituents to occupy the In(1) site (random occupation = 20percent). In addition, f_In(1) ranges from 70percent to 100percent for M=Hg in the order T=Co,Rh, and Ir. These fractions track the changes in the atomic radii of the various species, and help explain the sharp dependence of $T_c$ on substituting into the In site. However, it is difficult to reconcile …

The objectives of this paper are: (1) validate H{sub 2} FC vehicles and infrastructure in parallel; (2) identify current status and evolution of the technology; (3) objectively assess progress toward technology readiness; and (4) provide feedback to H{sub 2} research and development.

We report an analysis of {tau}{sup -} decaying into {omega}{pi}{sup -} {nu}{sub {tau}} with {omega} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup 0} using a data sample containing nearly 320 million {tau} pairs collected with the BABAR detector at the PEP-II B-Factory. We find no evidence for second-class currents and we set an upper limit of 0.69% at 90% confidence level for the fraction of second-class currents in this decay mode.

Many computers were designed to store a two-digit number for the year, which makes the year 2000 indistinguishable from 1900. Unless they are corrected, many computers will not be able to process dates beyond the year 2000, and may cause many costly problems in commerce and government. In the 106th Congress, hearings are being held and will continue to provide the public with the most accurate information available on the status of Y2K remediations at federal agencies, state and local agencies, private sector entities, and international organizations. Congress may also consider additional legislation to ensure that private sector systems are compliant, to establish emergency preparedness measures to address problems that might occur, and to limit liability associated with Y2K failures for manufacturers and industry groups.

A high contrast 12.6 keV Kr K{alpha} source has been demonstrated on the petawatt-class Titan laser facility. The contrast ratio (K{alpha} to continuum) is 65, with a competitive ultra short pulse laser to x-ray conversion efficiency of 10{sup -5}. Filtered shadowgraphy indicates that the Kr K{alpha} and K{beta} x-rays are emitted from a roughly 1 x 2 mm emission volume, making this source suitable for area backlighting and scattering. Spectral calculations indicate a typical bulk electron temperature of 50-70 eV (i.e. mean ionization state 13-16), based on the observed ratio of K{alpha} to K{beta}. Kr gas jets provide a debris-free high energy K{alpha} source for time-resolved diagnosis of dense matter.

Several approaches to ASP performance can be contemplated. Perhaps the ideal would be a full cost/benefit analysis (which is probably utterly infeasible). Another approach would be a test-based figure-of-merit (FOM), this approach has the virtue of being quantitative and the challenge that each customer and application would be characterized by a different FOM. The alternative proposed here is an approach that uses information about the limits of detection of real instruments to support informed judgments.

The Advanced Telecommunications Computing Architecture is a new industry open standard for electronics instrument modules and shelves being evaluated for the International Linear Collider (ILC). It is the first industrial standard designed for High Availability (HA). ILC availability simulations have shown clearly that the capabilities of ATCA are needed in order to achieve acceptable integrated luminosity. The ATCA architecture looks attractive for beam instruments and detector applications as well. This paper provides an overview of ongoing R&D including application of HA principles to power electronics systems.
