Members of the uniformed services and U.S. citizens who live abroad are eligible to register and vote absentee in federal elections under the Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA, P.L. 99-410, 42 U.S.C.1973ff) of 1986. The law was enacted to improve absentee registration and voting for this group of voters and to consolidate existing laws. Since 1942, a number of federal laws have been enacted to assist these voters: the Soldier Voting Act of 1942 (amended in 1944), the Federal Voting Assistance Act of 1955, the Overseas Citizens Voting Rights Act of 1975 (both the 1955 and 1975 laws were amended in 1978 to improve procedures), and the Uniformed and Overseas Citizens Absentee Voting Act of 1986. The law is administered by the Secretary of Defense, who delegates that responsibility to the director of the Federal Voting Assistance Program at the Department of Defense (DOD).

Testimony issued by the Government Accountability Office with an abstract that begins "The federal government is the world's largest and most complex entity, with about $3.5 trillion in outlays in fiscal year 2010 funding a broad array of programs and operations. GAO maintains a program to focus attention on government operations that it identifies as high risk due to their greater vulnerabilities to fraud, waste, abuse, and mismanagement or the need for transformation to address economy, efficiency, or effectiveness challenges. This testimony summarizes GAO's 2011 High-Risk Update, which describes the status of high-risk areas listed in 2009 and identifies any new high-risk area needing attention by Congress and the executive branch. Solutions to high-risk problems offer the potential to save billions of dollars, improve service to the public, and strengthen the performance and accountability of the U.S. government."

A letter report issued by the Government Accountability Office with an abstract that begins "Congress established two CMS-administered programs--the Electronic Prescribing Program and the Electronic Health Records (EHR) Program--that provide incentive payments to eligible Medicare providers who adopt and use health information technology, and penalties for those who do not. The Medicare Improvements for Patients and Providers Act of 2008 required GAO to report on the Electronic Prescribing Program. To do so, GAO examined how CMS determines which providers receive incentive payments and avoid penalties from that program and how many providers received incentive payments in 2009. Also, GAO was asked to examine how the requirements of the two programs compare. GAO reviewed relevant laws and regulations, interviewed CMS officials, and analyzed CMS data on incentive payments made for 2009, which were the most recent data available for a full year."

Correspondence issued by the Government Accountability Office with an abstract that begins "Pakistan is a key U.S. ally in the effort to combat terrorism and violent extremism. Taliban, al Qaeda, and other terrorists have used parts of Pakistan to plan and launch attacks on Afghan, U.S., and NATO security forces in Afghanistan, as well as on Pakistani citizens and security forces in Pakistan. Enhancing the effectiveness of civilian assistance to Pakistan is one of the U.S. government's top foreign policy and national security priorities. Foreign assistance is vital to help the government of Pakistan overcome the political, economic, and security challenges that threaten Pakistan's long-term stability. Since 2002, the United States has provided over $18 billion in foreign assistance and reimbursements to Pakistan, about two-thirds of which has been security-related. In October 2009, Congress passed the Enhanced Partnership with Pakistan Act of 2009, which authorizes up to $1.5 billion a year for development, economic, and democratic assistance (henceforth referred to as "civilian assistance") to Pakistan for fiscal years 2010 through 2014. In the act, Congress declares that the United States requires a balanced, integrated, countrywide strategy to support Pakistan's efforts that does not disproportionately focus on security-related assistance. The act …

Some ionic liquids (ILs) have been shown to be very effective solvents for biomass pretreatment. It is known that some ILs can have a strong inhibitory effect on fungal cellulases, making the digestion of cellulose inefficient in the presence of ILs. The identification of IL-tolerant enzymes that could be produced as a cellulase cocktail would reduce the costs and water use requirements of the IL pretreatment process. Due to their adaptation to high salinity environments, halophilic enzymes are hypothesized to be good candidates for screening and identifying IL-resistant cellulases. Using a genome-based approach, we have identified and characterized a halophilic cellulase (Hu-CBH1) from the halophilic archaeon, Halorhabdus utahensis. Hu-CBH1 is present in a gene cluster containing multiple putative cellulolytic enzymes. Sequence and theoretical structure analysis indicate that Hu-CBH1 is highly enriched with negatively charged acidic amino acids on the surface, which may form a solvation shell that may stabilize the enzyme, through interaction with salt ions and/or water molecules. Hu-CBH1 is a heat tolerant haloalkaliphilic cellulase and is active in salt concentrations up to 5 M NaCl. In high salt buffer, Hu-CBH1 can tolerate alkali (pH 11.5) conditions and, more importantly, is tolerant to high levels (20percent w/w) of ILs, …

We have studied the efficacy of using nuclear resonance fluorescence (NRF)-based techniques to assay spent nuclear fuel for Pu content using quasi-monoenergetic sources. We have developed two techniques to precisely determine the Pu content in a fuel rod/pin. One of our approaches is virtually free of systematic uncertainties. Using analytical models, we have determined the amount of time required to measure the Pu content in spent nuclear fuel rods and spent fuel assemblies to within 1% precision. We note that Pu content can be determined in a fuel assembly about as fast as in a single fuel pin. The performance of NRF-based assay techniques with improved photon sources, which are currently under development, will also estimated. For follow-on research we propose to: (1) Construct research prototype detection systems for both of the NRF-based assay systems proposed in this paper and measure their calibration curves; (2) Determine the systematic errors associated with both assay methods, explore ways to reduce the errors and fold the results into future performance calculations; (3) Develop an algorithm to assay a fuel assembly; (4) Perform validation measurements using a single pin and scaled assemblies; (5) Research and develop current-mode detection and/or threshold detection techniques to improve …

This report evaluates the conceptual plans for a one-tonne (S4) cryostat cooling design. This document is based upon previous design work and experimental results used to evaluate the current MAJORANA DEMONSTRATOR (MJD) thermal design. A feasibility study of a cooling system for S4 based on the MJD thermosyphon experiment is presented. The one-tonne experiment will be a scaled up version of the MJD. There will be many cryostats for the S4 experiment. In this document a cryostat with up to 19 strings of Germanium crystals is analyzed. Aside from an extra outer ring of crystals, the geometry of both systems’ cryostats is very similar. The materials used in the fabrication of both ultra-low background experiments will be underground electroformed copper. The current MJD uses a two-phase liquid-gas cooling system to ensure constant operating temperature. This document presents a theoretical investigation of a cooling system for the S4 experiment and evaluates the heat transfer performance requirements for such a system.

Catalysts provide foundational technology for the development of new materials and can enhance the efficiency of routes to known materials. New catalyst technologies offer the possibility of reducing energy and raw material consumption as well as enabling chemical processes with a lower environmental impact. The rising demand and expense of fossil resources has strained national and global economies and has increased the importance of accessing more efficient catalytic processes for the conversion of hydrocarbons to useful products. The goals of the research are to develop and understand single-site homogeneous catalysts for the conversion of readily available hydrocarbons into useful materials. A detailed understanding of these catalytic reactions could lead to the development of catalysts with improved activity, longevity and selectivity. Such transformations could reduce the environmental impact of hydrocarbon functionalization, conserve energy and valuable fossil resources and provide new technologies for the production of liquid fuels. This project is a collaborative effort that incorporates both experimental and computational studies to understand the details of transition metal catalyzed C-H activation and C-C bond forming reactions with olefins. Accomplishments of the current funding period include: (1) We have completed and published studies of C-H activation and catalytic olefin hydroarylation by TpRu{l_brace}P(pyr){sub 3}{r_brace}(NCMe)R …

Ignition capsule designs for the National Ignition Facility (NIF) [G. H. Miller, E. I. Moses, and C. R. Wuest, Opt. Eng. 443, 2841 (2004)] have continued to evolve in light of improved physical data inputs, improving simulation techniques, and - most recently - experimental data from a growing number of NIF sub-ignition experiments. This paper summarizes a number of recent changes to the cryogenic capsule design and some of our latest techniques in simulating its performance. Specifically, recent experimental results indicated harder x-ray drive spectra in NIF hohlraums than were predicted and used in previous capsule optimization studies. To accommodate this harder drive spectrum, a series of high-resolution 2-D simulations, resolving Legendre mode numbers as high as two thousand, were run and the germanium dopant concentration and ablator shell thicknesses re-optimized accordingly. Simultaneously, the possibility of cooperative or nonlinear interaction between neighboring ablator surface defects has motivated a series of fully 3-D simulations run with the massively parallel HYDRA code. These last simulations include perturbations seeded on all capsule interfaces and can use actual measured shell surfaces as initial conditions. 3-D simulations resolving Legendre modes up to two hundred on large capsule sectors have run through ignition and burn, and …

The separation of actinides and other elements of interest for nuclear forensics and threat reduction is currently performed using decades-old chemistries and ion-exchange columns. We propose to determine the technical feasibility of a novel method for separating actinide ions in solution. This method is based upon isotachophoresis (ITP), which has been applied in the purification of pharmaceuticals and other biochemical applications. This technique has the potential to separate inorganic ions more effectively than existing methods, which is key to analyzing very small samples. We will perform a quantitative assessment of the effectiveness of specific isotachophoretic approaches including predicting the physical and chemical properties, such as ion mobility, of inorganic ions under specific solvent conditions using a combination of ab initio calculations and semi-empirical methods. We expect to obtain a thorough understanding of the analytical systems parameters under which ITP is most effective for the separation of inorganic samples, including the influence of the double layer surrounding actinide ions, the Debye length for different ions and ion complexes, and Debye-Hueckel limits. Inorganic separations are key to nuclear forensics for countering terrorism and nuclear proliferation. If found to be feasible and potentially superior to currently used separation approaches, ITP could provide the …
