Border Security: State Department Should Plan for Potentially Significant Staffing and Facilities Shortfalls Caused by Changes in the Visa Waiver Program (open access)

Border Security: State Department Should Plan for Potentially Significant Staffing and Facilities Shortfalls Caused by Changes in the Visa Waiver Program

A letter report issued by the Government Accountability Office with an abstract that begins "Under the Visa Waiver Program (VWP), citizens from 27 countries can travel to the United States visa free. Terrorism concerns involving VWP country citizens have led some to suggest eliminating or suspending the program, while the executive branch is considering adding countries to it. Legislation passed in 2007 led the Department of Homeland Security (DHS) to develop its Electronic System for Travel Authorization (ESTA), to screen VWP country citizens before they travel to the United States; if found ineligible, travelers will need to apply for a visa. GAO reviewed how (1) program elimination or suspension, (2) program expansion, and (3) ESTA could affect visa demand, resource needs, and revenues. We collected traveler, staffing, facilities, and cost data from the Department of State (State), DHS, and embassy officials and developed estimates related to the three scenarios above."

High-Containment Biosafety Laboratories: DHS Lacks Evidence to Conclude That Foot-and-Mouth Disease Research Can Be Done Safely on the U.S. Mainland (open access)

High-Containment Biosafety Laboratories: DHS Lacks Evidence to Conclude That Foot-and-Mouth Disease Research Can Be Done Safely on the U.S. Mainland

Testimony issued by the Government Accountability Office with an abstract that begins "DHS is proposing to move foot-and mouth disease (FMD) research from its current location at the Plum Island Animal Disease Center--located on a federally owned island off the northern tip of Long Island, New York--and potentially onto the United States mainland. FMD is the most highly infectious animal disease that is known. Nearly 100 percent of exposed animals become infected. A single outbreak of FMD on the U.S. mainland could have significant economic consequences. Concerns have been raised about moving FMD research off its island location and onto the U.S. mainland--where it would be in closer proximity to susceptible animal populations--as opposed to building a new facility on the island. GAO was asked to evaluate the evidence DHS used to support its decision that FMD work can be done safely on the U.S. mainland, whether an island location provides any additional protection over and above that provided by modern high containment laboratories on the mainland, and the economic consequences of an FMD outbreak on the U.S. mainland. In preparing this testimony, GAO interviewed officials from DHS and USDA, talked with experts in FMD and high-containment laboratories worldwide, and …

Medicare Part D Low-Income Subsidy: SSA Continues to Approve Applicants, but Millions of Individuals Have Not Yet Applied (open access)

Medicare Part D Low-Income Subsidy: SSA Continues to Approve Applicants, but Millions of Individuals Have Not Yet Applied

Testimony issued by the Government Accountability Office with an abstract that begins "To help the elderly and disabled with prescription drug costs, the Congress passed the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (MMA), which created a voluntary outpatient prescription drug benefit (Medicare Part D). A key element of the prescription drug benefit is the low-income subsidy, or "extra help," available to Medicare beneficiaries with limited income and resources to assist them in paying their premiums and other out-of-pocket costs. To assess the Social Security Administration's (SSA) implementation of the subsidy, GAO is providing information on (1) the number of applicants approved for or denied the low-income subsidy and (2) challenges of identifying individuals eligible for the subsidy and targeting outreach efforts. This statement is based on a prior GAO report on the subsidy and associated spending issued in May 2007, selected aspects of which we updated in May 2008."

Sulfidation of Cadmium at the Nanoscale (open access)

Sulfidation of Cadmium at the Nanoscale

We investigate the evolution of structures that result when spherical Cd nanoparticles of a few hundred nanometers in diameter react with dissolved molecular sulfur species in solution to form hollow CdS. Over a wide range of temperatures and concentrations, we find that rapid Cd diffusion through the growing CdS shell localizes the reaction front at the outermost CdS/S interface, leading to hollow particles when all the Cd is consumed. When we examine partially reacted particles, we find that this system differs significantly from others in which the nanoscale Kirkendall effect has been used to create hollow particles. In previously reported systems, partial reaction creates a hollow particle with a spherically symmetric metal core connected to the outer shell by filaments. In contrast, here we obtain a lower symmetry structure, in which the unreacted metal core and the coalesced vacancies separate into two distinct spherical caps, minimizing the metal/void interface. This pattern of void coalescence is likely to occur in situations where the metal/vacancy self-diffusivities in the core are greater than the diffusivity of the cations through the shell.

Modification of the GS LT Paired-end Library Protocol for Constructing Longer Insert Size Libraries (open access)

Modification of the GS LT Paired-end Library Protocol for Constructing Longer Insert Size Libraries

Paired-end library sequencing has been proven useful in scaffold construction during de novo assembly of genomic sequences. The ability of generating mate pairs with 8 Kb or greater insert sizes is especially important for genomes containing long repeats. While the current 454 GS LT Paired-end library preparation protocol can successfully construct libraries with 3 Kb insert size, it fails to generate longer insert sizes because the protocol is optimized to purify shorter fragments. We have made several changes in the protocol in order to increase the fragment length. These changes include the use of Promega column to increase the yield of large size DNA fragments, two gel purification steps to remove contaminated short fragments, and a large reaction volume in the circularization step to decrease the formation of chimeras. We have also made additional changes in the protocol to increase the overall quality of the libraries. The quality of the libraries are measured by a set of metrics, which include levels of redundant reads, linker positive, linker negative, half linker reads, and driver DNA contamination, and read length distribution, were used to measure the primary quality of these libraries. We have also assessed the quality of the resulted mate pairs …

Quantum Dynamical Behaviour in Complex Systems - A Semiclassical Approach (open access)

Quantum Dynamical Behaviour in Complex Systems - A Semiclassical Approach

One of the biggest challenges in Chemical Dynamics is describing the behavior of complex systems accurately. Classical MD simulations have evolved to a point where calculations involving thousands of atoms are routinely carried out. Capturing coherence, tunneling and other such quantum effects for these systems, however, has proven considerably harder. Semiclassical methods such as the Initial Value Representation (SC-IVR) provide a practical way to include quantum effects while still utilizing only classical trajectory information. For smaller systems, this method has been proven to be most effective, encouraging the hope that it can be extended to deal with a large number of degrees of freedom. Several variations upon the original idea of the SCIVR have been developed to help make these larger calculations more tractable; these range from the simplest, classical limit form, the Linearized IVR (LSC-IVR) to the quantum limit form, the Exact Forward-Backward version (EFB-IVR). In this thesis a method to tune between these limits is described which allows us to choose exactly which degrees of freedom we wish to treat in a more quantum mechanical fashion and to what extent. This formulation is called the Tuning IVR (TIVR). We further describe methodology being developed to evaluate the prefactor …

Synthesis of Remote Sensing and Field Observations to Model and Understand Disturbance and Climate Effects on the Carbon Balance of Oregon & Northern California (open access)

Synthesis of Remote Sensing and Field Observations to Model and Understand Disturbance and Climate Effects on the Carbon Balance of Oregon & Northern California

The goal is to quantify and explain the carbon (C) budget for Oregon and N. California. The research compares "bottom -up" and "top-down" methods, and develops prototype analytical systems for regional analysis of the carbon balance that are potentially applicable to other continental regions, and that can be used to explore climate, disturbance and land-use effects on the carbon cycle. Objectives are: 1) Improve, test and apply a bottom up approach that synthesizes a spatially nested hierarchy of observations (multispectral remote sensing, inventories, flux and extensive sites), and the Biome-BGC model to quantify the C balance across the region; 2) Improve, test and apply a top down approach for regional and global C flux modeling that uses a model-data fusion scheme (MODIS products, AmeriFlux, atmospheric CO2 concentration network), and a boundary layer model to estimate net ecosystem production (NEP) across the region and partition it among GPP, R(a) and R(h). 3) Provide critical understanding of the controls on regional C balance (how NEP and carbon stocks are influenced by disturbance from fire and management, land use, and interannual climate variation). The key science questions are, "What are the magnitudes and distributions of C sources and sinks on seasonal to decadal …

CHARACTERIZATION OF SAMPLES FROM TANK 16H ANNULUS (open access)

CHARACTERIZATION OF SAMPLES FROM TANK 16H ANNULUS

In support of the closure of Tank 16H, the remaining waste material in the tank annulus must be removed. Samples of the waste material from Tank 16H annulus were obtained and sent to Savannah River National Laboratory (SRNL) to determine the chemical and radiochemical composition prior to further waste removal. The three samples obtained from the Tank 16H annulus show some similarity as to the types of mineral phases present in the materials but differ in the relative amounts of each phase present. The samples from outside the dehumidification duct at two locations in the annulus show very different compositions and estimated solubility in water. This indicates the waste material in Tank 16H annulus may have a wide range of compositions at different locations. The table below provides a simplified description of the composition of each sample. The limited characterization techniques conducted and the complex mixture of materials in each sample makes assigning a definitive composition for each sample difficult. Given the variability in composition with just the three small samples characterized, a more detailed description of any single sample may be of limited value.

Enantioselective Intramolecular Hydroarylation of Alkenes via Directed C-H Bond Activation (open access)

Enantioselective Intramolecular Hydroarylation of Alkenes via Directed C-H Bond Activation

Highly enantioselective catalytic intramolecular ortho-alkylation of aromatic imines containing alkenyl groups tethered at the meta position relative to the imine directing group has been achieved using [RhCl(coe){sub 2}]{sub 2} and chiral phosphoramidite ligands. Cyclization of substrates containing 1,1- and 1,2-disubstituted as well as trisubstituted alkenes were achieved with enantioselectivities >90% ee for each substrate class. Cyclization of substrates with Z-alkene isomers proceeded much more efficiently than substrates with E-alkene isomers. This further enabled the highly stereoselective intramolecular alkylation of certain substrates containing Z/E-alkene mixtures via a Rh-catalyzed alkene isomerization with preferential cyclization of the Z-isomer.
