In this work, we investigate the effect of air convection on laser-beam pointing noise essential for the long trace profiler (LTP). We describe this pointing error with noise power density (NPD) frequency distributions. It is shown that the NPD spectra due to air convection have a very characteristic form. In the range of frequencies from {approx}0.05 Hz to {approx}0.5 Hz, the spectra can be modeled with an inverse-power-law function. Depending on the intensity of air convection that is controlled with a resistive heater of 100 to 150 mW along a one-meter-long optical path, the power index lies between 2 and 3 at an overall rms noise of {approx}0.5 to 1 microradian. The efficiency of suppression of the convection noise by blowing air across the beam optical path is also discussed. Air-blowing leads to a white-noise-like spectrum. Air blowing was applied to the reference channel of an LTP allowing demonstration of the contribution of air convection noise to the LTP reference beam. The ability to change (with the blowing technique presented) the spectral characteristics of the beam pointing noise due to air convection allows one to investigate the contribution of the convection effect, and thus make corrections to the power spectral …

On May 3, 2006, the home of a Department of Veterans Affairs (VA) data analyst was burglarized, resulting in the theft of a laptop computer and an external data storage device that was reported to contain personal information on more than 26 million veterans and United States military personnel. The VA Secretary testified that he was not informed of the incident until May 16, 2006, almost two weeks after the data had been stolen. VA publicly announced the theft on May 22. On June 29, VA announced that the stolen laptop computer and external hard drive had been recovered intact and that, based on a forensic examination conducted by the Federal Bureau of Investigation (FBI), the files on the external hard drive had not been compromised.

Background: Molecular evolutionary studies of noncodingsequences rely on multiple alignments. Yet how multiple alignmentaccuracy varies across sequence types, tree topologies, divergences andtools, and further how this variation impacts specific inferences,remains unclear. Results: Here we develop a molecular evolutionsimulation platform, CisEvolver, with models of background noncoding andtranscription factor binding site evolution, and use simulated alignmentsto systematically examine multiple alignment accuracy and its impact ontwo key molecular evolutionary inferences: transcription factor bindingsite conservation and divergence estimation. We find that the accuracy ofmultiple alignments is determined almost exclusively by the pairwisedivergence distance of the two most diverged species and that additionalspecies have a negligible influence on alignment accuracy. Conservedtranscription factor binding sites align better than surroundingnoncoding DNA yet are often found to be misaligned at relatively shortdivergence distances, such that studies of binding site gain and losscould easily be confounded by alignment error. Divergence estimates frommultiple alignments tend to be overestimated at short divergencedistances but reach a tool specific divergence at which they cease toincrease, leading to underestimation at long divergences. Our moststriking finding was that overall alignment accuracy, binding sitealignment accuracy and divergence estimation accuracy vary greatly acrossbranches in a tree and are most accurate for terminal branches connectingsister taxa and least …

Mineral carbonation is a promising concept for permanent CO{sub 2} sequestration due to the vast natural abundance of the raw materials and the permanent storage of CO{sub 2} in solid form as carbonates. The sequestration of CO{sub 2} through the employment of magnesium silicates--olivine and serpentine--is beyond the proof of concept stage. For the work done in this project, serpentine was chosen as the feedstock mineral due to its abundance and availability. Although the reactivity of olivine is greater than that of serpentine, physical and chemical treatments have been shown to increase greatly the reactivity of serpentine. The primary drawback to mineral carbonation is reaction kinetics. To accelerate the carbonation, aqueous processes are preferred, where the minerals are first dissolved in solution. In aqueous carbonation, the key step is the dissolution rate of the mineral, where the mineral dissolution reaction is likely to be surface-controlled. The relatively low reactivity of serpentine has warranted research into physical and chemical treatments that have been shown to greatly increase its reactivity. The use of sulfuric acid as an accelerating medium for the removal of magnesium from serpentine has been investigated. To accelerate the dissolution process, the mineral can be ground to very fine …

This report examines the role of state and local law enforcement in enforcing immigration law. The discussion is limited to the role of state and local law enforcement in the investigation, arrest, and detention of all immigration violators. The report does not discuss the prosecution, adjudication, or removal of aliens who violate the law. The report opens with a brief discussion of the types of immigration interior enforcement activities that the former Immigration and Naturalization Service (INS) pursued and the current immigration activities that are now the focus of the Department of Homeland Security (DHS). A discussion of the legal authority that permits state and local law enforcement to enforce immigration law under certain circumstances follows. Current administrative efforts to involve state and local law enforcement in enforcing immigration law as well as selected issues are discussed. The report concludes with a discussion of the pros and cons of such a policy and an analysis of policy options for Congress.

A letter report issued by the Government Accountability Office with an abstract that begins "A well-defined enterprise architecture is an essential tool for leveraging information technology (IT) to transform business and mission operations. GAO's experience has shown that attempting to modernize and evolve IT environments without an architecture to guide and constrain investments results in operations and systems that are duplicative, not well integrated, costly to maintain, and ineffective in supporting mission goals. In light of the importance of enterprise architectures, GAO developed a five stage architecture management maturity framework that defines what needs to be done to effectively manage an architecture program. Under GAO's framework, a fully mature architecture program is one that satisfies all elements of all stages of the framework. As agreed, GAO's objective was to determine the status of major federal department and agency enterprise architecture efforts."

As the development of extreme ultraviolet (EUV) lithography progresses, interest grows in the extension of traditional optical components to the EUV regime. The strong absorption of EUV by most materials and its extremely short wavelength, however, makes it very difficult to implement many components that are commonplace in the longer wavelength regimes. One such component is the diffractive optical element used, for example, in illumination systems to efficiently generate modified pupil fills. Here we demonstrate the fabrication and characterization of EUV binary phase-only computer-generated holograms allowing arbitrary far-field diffraction patterns to be generated.

The Coast Guard is the lead federal agency for maritime homeland security. For FY2007, the Coast Guard is requesting a total of about $4.5 billion for missions defined in The Homeland Security Act of 2002 as the Coast Guard's homeland security missions. This equates to about 54% of the Coast Guard's total requested FY2007 budget. The Coast Guard's homeland security operations pose several potential issues for Congress, including adequacy of Coast Guard resources for performing both homeland security and non-homeland security missions, and Coast Guard coordination with other agencies involved in maritime homeland security.
