Defined Benefit Plans: Proposed Plan Buyouts by Financial Firms Pose Potential Risks and Benefits (open access)

Defined Benefit Plans: Proposed Plan Buyouts by Financial Firms Pose Potential Risks and Benefits

A letter report issued by the Government Accountability Office with an abstract that begins "Some U.S. financial and pension consulting firms have recently proposed alternatives to terminating a defined benefit (DB) pension plan and contracting with insurance companies to pay promised benefits. In their proposals, a plan sponsor would typically transfer the assets and liabilities of a hard-frozen DB plan--one in which all participant benefit accruals have ceased--along with additional money, to a financial entity, which would become the new sponsor. Such buyouts would have implications for participants, plan sponsors, and the Pension Benefit Guaranty Corporation (PBGC), the federal agency that insures private DB plans. This report addresses the following questions: (1) What is the basic model of proposed sales of frozen DB plans to third-party financial firms and how does it compare with a standard plan termination? (2) What are the potential risks and benefits of plan buyouts for participants, PBGC, plan sponsors, and other stakeholders? To address these questions, GAO reviewed proposed models for plan buyouts and analyzed regulatory and statutory issues associated with terminations and buyouts. GAO also interviewed labor and pension advocacy groups, pension regulatory agencies, and pension experts."

Nuclear Security: Better Oversight Needed to Ensure That Security Improvements at Lawrence Livermore National Laboratory Are Fully Implemented and Sustained (open access)

Nuclear Security: Better Oversight Needed to Ensure That Security Improvements at Lawrence Livermore National Laboratory Are Fully Implemented and Sustained

A letter report issued by the Government Accountability Office with an abstract that begins "In April 2008, the Department of Energy's (DOE) security inspection at Lawrence Livermore National Laboratory (LLNL) found significant weaknesses, particularly in LLNL's protective force's ability to assure the protection of weapons-grade (special) nuclear material. LLNL is overseen by the National Nuclear Security Administration (NNSA), a separately organized agency within DOE, and managed by a contractor. NNSA is planning to remove most of the special nuclear material from LLNL. GAO was asked to (1) characterize security deficiencies identified in the 2008 inspection; (2) determine the factors that contributed to these deficiencies; (3) identify LLNL's corrective actions to address security deficiencies; and (4) assess LLNL's plan to permanently remove the riskiest special nuclear material from its site. To conduct this work, GAO visited LLNL, reviewed numerous documents and plans, and interviewed LLNL and NNSA security officials."

Information Security: Securities and Exchange Commission Needs to Consistently Implement Effective Controls (open access)

Information Security: Securities and Exchange Commission Needs to Consistently Implement Effective Controls

A letter report issued by the Government Accountability Office with an abstract that begins "In carrying out its mission to ensure that securities markets are fair, orderly, and efficiently maintained, the Securities and Exchange Commission (SEC) relies extensively on computerized systems. Effective information security controls are essential to ensure that SEC's financial and sensitive information is protected from inadvertent or deliberate misuse, disclosure, or destruction. As part of its audit of SEC's financial statements, GAO assessed (1) the status of SEC's actions to correct previously reported information security weaknesses and (2) the effectiveness of SEC's controls for ensuring the confidentiality, integrity, and availability of its information systems and information. To do this, GAO examined security policies and artifacts, interviewed pertinent officials, and conducted tests and observations of controls in operation."

Material properties limiting the performance of CZT gamma-ray detectors (open access)

Material properties limiting the performance of CZT gamma-ray detectors

CdZnTe (CZT) nuclear radiation detectors are advanced sensors that utilize innovative technologies developed for wide band-gap semiconductor industry and microelectronics. They open opportunities for new types of room-temperature operating, field deployable instruments that provide accurate identification of potential radiological threats and timely awareness for both the civilian and military communities. Room-temperature radiation detectors are an emerging technology that relies on the use of high-quality CZT crystals whose availability is currently limited by material non-uniformities and the presence of extended defects. To address these issues, which are most critical to CZT sensor developments, we developed X-ray mapping and IR transmission microscopy systems to characterize both CZT crystals and devices. Since a customized system is required for such X-ray measurements, we use synchrotron radiation beams available at BNL's National Synchrotron Light Source. A highly-collimated and high-intensity X-ray beam supports measurements of areas as small as 10 x 10 {micro}m{sup 2}, and allowed us to see fluctuations in collected charge over the entire area of the detector in a reasonable time. The IR microscopy system allows for 3D visualization of Te inclusions and other extended defects. In this paper, we describe the experimental techniques used in our measurements and typical results obtained from …

ADVANCES IN SE-79 ANALYSES ON SAVANNAH RIVER SITE RADIOACTIVE WASTE MATRICES (open access)

ADVANCES IN SE-79 ANALYSES ON SAVANNAH RIVER SITE RADIOACTIVE WASTE MATRICES

Waste cleanup efforts underway at the United States Department of Energy's (DOE) Savannah River Site (SRS) in South Carolina, as well as other DOE nuclear sites, have created a need to characterize {sup 79}Se in radioactive waste inventories. Successful analysis of {sup 79}Se in high activity waste matrices is challenging for a variety of reasons. As a result of these unique challenges, the successful quantification of {sup 79}Se in the types of matrices present at SRS requires an extremely efficient and selective separation of {sup 79}Se from high levels of interfering radionuclides. A robust {sup 79}Se radiochemical separation method has been developed at the Savannah River National Laboratory (SRNL) which is routinely capable of successfully purifying {sup 79}Se from a wide range of interfering radioactive species. In addition to a dramatic improvements in the Kd, ease, and reproducibility of the analysis, the laboratory time has been reduced from several days to only 6 hours.

Structured hints : extracting and abstracting domain expertise. (open access)

Structured hints : extracting and abstracting domain expertise.

We propose a new framework for providing information to help optimize domain-specific application codes. Its design addresses problems that derive from the widening gap between the domain problem statement by domain experts and the architectural details of new and future high-end computing systems. The design is particularly well suited to program execution models that incorporate dynamic adaptive methodologies for live tuning of program performance and resource utilization. This new framework, which we call 'structured hints', couples a vocabulary of annotations to a suite of performance metrics. The immediate target is development of a process by which a domain expert describes characteristics of objects and methods in the application code that would not be readily apparent to the compiler; the domain expert provides further information about what quantities might provide the best indications of desirable effect; and the interactive preprocessor identifies potential opportunities for the domain expert to evaluate. Our development of these ideas is progressing in stages from case study, through manual implementation, to automatic or semi-automatic implementation. In this paper we discuss results from our case study, an examination of a large simulation of a neural network modeled after the neocortex.

THEORETICAL STUDY ON THE INTERACTION BETWEEN XENON AND POSITIVE SILVER CLUSTERS IN GAS PHASE AND ON THE (001) CHABAZITE SURFACE (open access)

THEORETICAL STUDY ON THE INTERACTION BETWEEN XENON AND POSITIVE SILVER CLUSTERS IN GAS PHASE AND ON THE (001) CHABAZITE SURFACE

A systematic study on the adsorption of xenon on silver clusters in the gas phase and on the (001) surface of silver-exchanged chabazite is reported. Density functional theory at the B3LYP level with the cluster model was employed. The results indicate that the dominant part of the binding is the {sigma} donation, which is the charge transfer from the 5p orbital of Xe to the 5s orbital of Ag and is not the previously suggested d{sub {pi}}-d{sub {pi}} back-donation. A correlation between the binding energy and the degree of {sigma} donation is found. Xenon was found to bind strongly to silver cluster cations and not to neutral ones. The binding strength decreases as the cluster size increases for both cases, clusters in the gas-phase and on the chabazite surface. The Ag{sup +} cation is the strongest binding site for xenon both in gas phase and on the chabazite surface with the binding energies of 73.9 and 14.5 kJ/mol, respectively. The results also suggest that the smaller silver clusters contribute to the negative chemical shifts observed in the {sup 129}Xe NMR spectra in experiments.
