A letter report issued by the Government Accountability Office with an abstract that begins "Annuities with guaranteed lifetime withdrawals can help older Americans ensure they do not outlive their assets, but do present some risks to consumers. Two such products, variable annuities with guaranteed lifetime withdrawal benefits (VA/GLWB) and contingent deferred annuities (CDA), share a number of features but have some important structural differences. For example, both provide consumers with access to investment assets and the guarantee of lifetime income, but while VA/GLWB assets are held in a separate account of the insurer for the benefit of the annuity purchaser, the assets covered by a CDA are generally held in an investment account owned by the CDA purchaser. Consumers can benefit from these products by having a steady stream of income regardless of how their investment assets perform or how long they live, while at the same time maintaining access to their assets for unexpected or other expenses. VA/GLWBs and CDAs are complex products that present some risks to consumers and require them to make multiple important decisions. For example, consumers might purchase an unsuitable product or make withdrawal decisions that could negatively affect their potential benefits. Several insurers and …

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2011, the Department of Homeland Security (DHS) reported data meeting its goal to secure the land border with a decrease in apprehensions; our data analysis showed that apprehensions decreased within each southwest border sector and by 68 percent in the Tucson sector from fiscal years 2006 to 2011, due in part to changes in the U.S. economy and achievement of Border Patrol strategic objectives. These data generally mirrored the decrease in estimated known illegal entries across locations. Other data are used by Border Patrol sector management to assess efforts in securing the border against the threat of illegal migration, drug smuggling, and terrorism; and Border Patrol may use these data to assess border security at the national level as the agency transitions to a new strategic plan. Our analysis of these data indicated that in the Tucson sector, there was little change in the percentage of estimated known illegal entrants apprehended by Border Patrol over the past 5 fiscal years, and the percentage of individuals apprehended who repeatedly crossed the border illegally declined across the southwest border by 6 percent from fiscal years …

A letter report issued by the Government Accountability Office with an abstract that begins "An annual average of 6.2 percent of noninstitutionalized children in Medicaid nationwide and 4.8 percent of privately insured children took one or more psychotropic medications, according to GAO's analysis of 2007-2009 data from the Department of Health and Human Services' (HHS) Medical Expenditure Panel Survey (MEPS). MEPS data also showed that children in Medicaid took antipsychotic medications (a type of psychotropic medication that can help some children but has a risk of serious side effects) at a relatively low rate--1.3 percent of children--but that the rate for children in Medicaid was over twice the rate for privately insured children, which was 0.5 percent. In addition, MEPS data showed that most children whose emotions or behavior, as reported by their parent or guardian, indicated a potential need for a mental health service did not receive any services within the same year. The Centers for Medicare & Medicaid Services (CMS) and many states have initiatives under way to help ensure that children receive appropriate mental health treatments. However, CMS's ability to monitor children's receipt of mental health services is limited because CMS does not collect information from states …

This report provides background information and potential oversight issues for Congress on the Ohio replacement program (ORP), a program to design and build a new class of 12 ballistic missile submarines (SSBNs) to replace the Navy's current force of 14 Ohio-class SSBNs. The Ohio replacement program is also known as the SSBN(X) program. The Navy's proposed FY2013 budget requests $564.9 million for continued research and development work on the Ohio replacement program. Decisions that Congress makes on the Ohio replacement program could substantially affect U.S. military capabilities and funding requirements, and the U.S. shipbuilding industrial base.

This report provides background information and presents potential issues for Congress concerning the Navy's ship force-structure goals and shipbuilding plans. The planned size of the Navy, the rate of Navy ship procurement, and the prospective affordability of the Navy's shipbuilding plans have been matters of concern for the congressional defense committees for the past several years. Decisions that Congress makes on Navy shipbuilding programs can substantially affect Navy capabilities and funding requirements, and the U.S. shipbuilding industrial base.

This report focuses on the potential implications of China's naval modernization for future required U.S. Navy capabilities. The question of how the United States should respond to China's military modernization effort, including its naval modernization effort, has emerged as a key issue in U.S. defense planning.

This report provides background information and identifies issues for Congress on Department of Defense (DOD) energy initiatives. DOD spends billions of dollars per year on fuel, and is pursuing numerous initiatives for reducing its fuel needs and changing the mix of energy sources that it uses. DOD's energy initiatives pose several potential policy and oversight issues for Congress, and have been topics of discussion and debate at hearings on DOD's proposed FY2013 budget. Congress' decisions on DOD energy initiatives could substantially affect DOD capabilities, funding requirements, and U.S. energy industries.

This final report summarizes activities and results at the University of North Carolina as part of the the SciDAC-2 Project The Secret Life of Quarks: National Computational Infrastructure for Lattice Quantum Chromodynamics. The overall objective of the project is to construct the software needed to study quantum chromo- dynamics (QCD), the theory of the strong interactions of subatomic physics, and similar strongly coupled gauge theories anticipated to be of importance in the LHC era. It built upon the successful efforts of the SciDAC-1 project National Computational Infrastructure for Lattice Gauge Theory, in which a QCD Applications Programming Interface (QCD API) was developed that enables lat- tice gauge theorists to make effective use of a wide variety of massively parallel computers. In the SciDAC-2 project, optimized versions of the QCD API were being created for the IBM Blue- Gene/L (BG/L) and BlueGene/P (BG/P), the Cray XT3/XT4 and its successors, and clusters based on multi-core processors and Infiniband communications networks. The QCD API is being used to enhance the performance of the major QCD community codes and to create new applications. Software libraries of physics tools have been expanded to contain sharable building blocks for inclusion in application codes, performance analysis and …

Research was completed at Savannah River National Laboratory (SRNL) to investigate processes related to the blending of radioactive, liquid waste, salt solutions in 4920 cubic meter, 25.9 meter diameter storage tanks. One process was the blending of large salt solution batches (up to 1135 ? 3028 cubic meters), using submerged centrifugal pumps. A second process was the disturbance of a settled layer of solids, or sludge, on the tank bottom. And a third investigated process was the settling rate of sludge solids if suspended into slurries by the blending pump. To investigate these processes, experiments, CFD models (computational fluid dynamics), and theory were applied. Experiments were performed using simulated, non-radioactive, salt solutions referred to as supernates, and a layer of settled solids referred to as sludge. Blending experiments were performed in a 2.44 meter diameter pilot scale tank, and flow rate measurements and settling tests were performed at both pilot scale and full scale. A summary of the research is presented here to demonstrate the adage that, ?One good experiment fixes a lot of good theory?. Experimental testing was required to benchmark CFD models, or the models would have been incorrectly used. In fact, CFD safety factors were established by …

The Modular Caustic-Side Solvent Extraction Unit (MCU) recently conducted an outage that included maintenance on the centrifugal contactors. Operations personnel observed solids or deposits in two contactors and attempted to collect samples for analyses by Savannah River National Laboratory (SRNL). The residues found in Extraction Contactor SEP-401 are a mixture of amorphous silica, aluminosilicate, titanium, and debris from low alloy steel. The solids contain low concentrations of plutonium and strontium. These isotopes are associated with the titanium that came from the monosodium titanate (MST) added in the Actinide Removal Process (ARP) most likely as leached Ti from the MST that precipitated subsequently in MCU. An attempt was also made to obtain samples from the contents of Wash Contactor SEP-702. However, sampling provide ineffective.
