A letter report issued by the Government Accountability Office with an abstract that begins "About two-thirds of drugs that are prescribed for children have not been studied and labeled for pediatric use, which places children at risk of being exposed to ineffective treatment or incorrect dosing. The Best Pharmaceuticals for Children Act (BPCA), enacted in 2002, encourages the manufacturers, or sponsors, of drugs that still have marketing exclusivity--that is, are on-patent--to conduct pediatric drug studies, as requested by the Food and Drug Administration (FDA). If they do so, FDA may extend for 6 months the period during which no equivalent generic drugs can be marketed. This is referred to as pediatric exclusivity. BPCA required that GAO assess the effect of BPCA on pediatric drug studies and labeling. As discussed with the committees of jurisdiction, GAO (1) assessed the extent to which pediatric drug studies were being conducted under BPCA for on-patent drugs, including when drug sponsors declined to conduct the studies; (2) evaluated the impact of BPCA on labeling drugs for pediatric use and the process by which the labeling was changed; and (3) illustrated the range of diseases treated by the drugs studied under BPCA. GAO examined data about …

A letter report issued by the Government Accountability Office with an abstract that begins "Absent reform, Social Security's financing gap will grow until currently scheduled benefits can no longer be paid in full. Recent reform proposals often include general revenue (GR)--a major change that can have significant implications for the budget as a whole. This report addresses these issues: (1) What information is available about GR in recent proposal scorings by Social Security's Office of the Chief Actuary (OCACT)? (2) What common mechanisms, especially GR mechanisms, are used to increase program revenue? (3) What are the implications of GR for the trust fund and the federal budget? We have prepared this report under the Comptroller General's statutory authority to conduct evaluations on his own initiative as part of a continued effort to assist Congress in addressing the challenges facing Social Security."

A letter report issued by the Government Accountability Office with an abstract that begins "Following the invasion of Iraq in March 2003--known as Operation Iraqi Freedom (OIF)--concerns were raised about how the Department of Defense (DOD) secured Iraqi conventional munitions storage sites during and after major combat operations. Because of the broad interest in this issue, GAO conducted this work under the Comptroller General's authority to conduct evaluations. This report examines (1) the security provided by U.S. forces over Iraqi conventional munitions storage sites and (2) DOD actions to mitigate risks associated with an adversary's conventional munitions storage sites for future operations on the basis of OIF lessons learned. To address these objectives, GAO reviewed OIF war plans, joint doctrine and policy, and intelligence reports, and interviewed senior-level DOD officials."

Tank Farms Operations removed an electrochemical noise probe from Tank 241-AN-107. In the field, the probe was cut into four sections, wrapped, and placed in a 55-gallon drum, This drum was delivered to the 222-S Laboratory. The 222 S Laboratory unpackaged the sections of the AN-107 electrochemical noise probe and examined the material for evidence of corrosion. Each of the four sections contained three C-ring and three bullet specimens. The specimens were examined for pitting corrosion, crevice corrosion, and stress corrosion cracking. No evidence of stress corrosion cracking was found in the stressed C-ring specimens. Minor pitting was evident on some surfaces. Crevice corrosion was the dominant type of corrosion observed.

This document outlines a proposal for extending UPC'spoint-to-point memcpy library with support for explicitly non-blockingtransfers, and non-contiguous (indexed and strided) transfers. Variousportions of this proposal could stand alone as independent extensions tothe UPC library. The designs presented here are heavily influenced byanalogous functionality which exists in other parallel communicationsystems, such as MPI, ARMCI, Titanium, and network hardware API's such asQuadrics elan, Infiniband vapi, IBM LAPI and Cray X-1. Each sectioncontains proposed extensions to the libraries in the UPC LanguageSpecification (section 7) and corresponding extensions to the GASNetcommunication system API.

This report provides information on groundwater monitoring at the K Basins during October, November, and December 2006. Conditions remained very similar to those reported in the previous quarterly report, with no evidence in monitoring results to suggest groundwater impact from current loss of basin water to the ground. The K Basins monitoring network will be modified in the coming months as a consequence of new wells having been installed near KW Basin as part of a pump-and-treat system for chromium contamination, and new wells installed between the KE Basin and the river to augment long-term monitoring in that area.

The Advanced Simulation and Computing (ASC) Program (formerly know as Accelerated Strategic Computing Initiative, ASCI) has led the world in capability computing for the last ten years. Capability computing is defined as a world-class platform (in the Top10 of the Top500.org list) with scientific simulations running at scale on the platform. Example systems are ASCI Red, Blue-Pacific, Blue-Mountain, White, Q, RedStorm, and Purple. ASC applications have scaled to multiple thousands of CPUs and accomplished a long list of mission milestones on these ASC capability platforms. However, the computing demands of the ASC and Stockpile Stewardship programs also include a vast number of smaller scale runs for day-to-day simulations. Indeed, every 'hero' capability run requires many hundreds to thousands of much smaller runs in preparation and post processing activities. In addition, there are many aspects of the Stockpile Stewardship Program (SSP) that can be directly accomplished with these so-called 'capacity' calculations. The need for capacity is now so great within the program that it is increasingly difficult to allocate the computer resources required by the larger capability runs. To rectify the current 'capacity' computing resource shortfall, the ASC program has allocated a large portion of the overall ASC platforms budget to …

Many provisions of the current omnibus farm bill, the Farm Security and Rural Investment Act of 2002, expire in 2007. Without new legislation, notably in the area of farm commodity and income support programs, permanent statutes will take effect. Most of these statutes were enacted decades ago and are no longer compatible with current national economic objectives, global trading rules, and federal budgetary of regulatory policies. This report follows major legislation relating to existing farm bill statues introduced in the House and Senate in the 110th Congress.

The Savannah River National Laboratory (SRNL) has developed, and continues to enhance, its integrated capability to evaluate the impact of proposed sludge preparation plans on the Defense Waste Processing Facility's (DWPF's) operation. One of the components of this integrated capability focuses on frit development which identifies a viable frit or frits for each sludge option being contemplated for DWPF processing. A frit is considered viable if its composition allows for economic fabrication and if, when it is combined with the sludge option under consideration, the DWPF property/composition models (the models of DWPF's Product Composition Control System (PCCS)) indicate that the combination has the potential for an operating window (a waste loading (WL) interval over which the sludge/frit glass system satisfies processability and durability constraints) that would allow DWPF to meet its goals for waste loading and canister production. This report documents the results of SRNL's efforts to identify candidate frit compositions and corresponding predicted operating windows (defined in terms of WL intervals) for the February 2007 compositional projection of Sludge Batch 4 (SB4) developed by the Liquid Waste Organization (LWO). The nominal compositional projection was used to assess projected operating windows (in terms of a waste loading interval over which …

The project covered by this report focused on development of efficient but robust non-linear inversion algorithms for electromagnetic induction data, in particular for data collected with multiple receivers, and multiple transmitters, a situation extremely common in eophysical EM subsurface imaging methods. A key observation is that for such multi-transmitter problems each step in commonly used linearized iterative limited memory search schemes such as conjugate gradients (CG) requires solution of forward and adjoint EM problems for each of the N frequencies or sources, essentially generating data sensitivities for an N dimensional data-subspace. These multiple sensitivities allow a good approximation to the full Jacobian of the data mapping to be built up in many fewer search steps than would be required by application of textbook optimization methods, which take no account of the multiplicity of forward problems that must be solved for each search step. We have applied this idea to a develop a hybrid inversion scheme that combines features of the iterative limited memory type methods with a Newton-type approach using a partial calculation of the Jacobian. Initial tests on 2D problems show that the new approach produces results essentially identical to a Newton type Occam minimum structure inversion, while running …
