This report provides background information and potential oversight issues for Congress on the Gerald R. Ford (CVN-78) class aircraft carrier program. Congress's decisions on the CVN-78 program could substantially affect Navy capabilities and funding requirements and the shipbuilding industrial base.

This report discusses the military-related cases involving sexual assaults by U.S. service members that have resulted in increased public and congressional interest in military discipline and the military justice system.

A letter report issued by the Government Accountability Office with an abstract that begins "Overall, trends in dental coverage show little change from 1996 to 2010--around 62 percent of individuals had coverage. The percentage of the population with private dental coverage decreased from 53 to 50 percent. Dental coverage through Medicaid or the State Children's Health Insurance Program (CHIP), which was established in 1997, rose from 9 to 13 percent. The increase was due primarily to an increase in the number of children covered by these federal-state health programs with mandated pediatric dental coverage. Individuals with no dental coverage decreased from 28 to 25 percent, and coverage for 10 to 12 percent of the population was unknown. Use of dental services--the percentage of individuals who had at least one dental visit--also remained relatively unchanged at around 40 percent from 1996 to 2010. Medicaid and CHIP beneficiaries, children in particular, showed increases in the use of dental services (from 28 to 37 percent), but still visited the dentist less often than privately insured children (58 percent in 2010)."

A letter report issued by the Government Accountability Office with an abstract that begins "As of January 7, 2013, the Food and Drug Administration's (FDA) Center for Tobacco Products (CTP) had finished initial, but not final, review steps for most of about 3,800 submissions for new tobacco products (those not on the market on February 15, 2007). Ninety-nine percent of the submissions received by FDA were made under the substantial equivalence (SE) pathway. CTP determines whether the new tobacco product in an SE submission has the same characteristics as a predicate tobacco product (a product commercially marketed in the United States on February 15, 2007, or previously found by FDA to be substantially equivalent) or has different characteristics that do not raise different questions of public health. Initial review steps include CTP's determination of whether the new product is a type regulated by FDA and whether the submission is missing information. For most SE submissions, CTP took more than a year and a half from the date a submission was received to the date these initial steps were completed. Of the 3,788 SE submissions, 3,165 were received by FDA prior to a statutory deadline (March 22, 2011) allowing the product …

Over the past five years, our activities have both established Kepler as a viable scientific workflow environment and demonstrated its value across multiple science applications. We have published numerous peer-reviewed papers on the technologies highlighted in this short paper and have given Kepler tutorials at SC06,SC07,SC08,and SciDAC 2007. Our outreach activities have allowed scientists to learn best practices and better utilize Kepler to address their individual workflow problems. Our contributions to advancing the state-of-the-art in scientific workflows have focused on the following areas. Progress in each of these areas is described in subsequent sections. Workflow development. The development of a deeper understanding of scientific workflows "in the wild" and of the requirements for support tools that allow easy construction of complex scientific workflows; Generic workflow components and templates. The development of generic actors (i.e.workflow components and processes) which can be broadly applied to scientific problems; Provenance collection and analysis. The design of a flexible provenance collection and analysis infrastructure within the workflow environment; and Workflow reliability and fault tolerance. The improvement of the reliability and fault-tolerance of workflow environments.

It is now firmly established that neutrinos, which are copiously produced in the hot and dense core of the supernova, play a role in the supernova explosion mechanism and in the synthesis of heavy elements through a phenomena known as r-process nucleosynthesis. They are also detectable in terrestrial neutrino experiments, and serve as a probe of the extreme environment and complex dynamics encountered in the supernova. The major goal of the UW research activity relevant to this project was to calculate the neutrino interaction rates in hot and dense matter of relevance to core collapse supernova. These serve as key input physics in large scale computer simulations of the supernova dynamics and nucleosynthesis being pursued at national laboratories here in the United States and by other groups in Europe and Japan. Our calculations show that neutrino production and scattering rate are altered by the nuclear interactions and that these modifications have important implications for nucleosynthesis and terrestrial neutrino detection. The calculation of neutrino rates in dense matter are difficult because nucleons in the dense matter are strongly coupled. A neutrino interacts with several nucleons and the quantum interference between scattering off different nucleons depends on the nature of correlations between …
