Securing, Stabilizing, and Rebuilding Iraq: Iraqi Government Has Not Met Most Legislative, Security, and Economic Benchmarks
Testimony issued by the Government Accountability Office with an abstract that begins "This testimony is intended to discuss our report on whether or not the government of Iraq has met 18 benchmarks contained in the U.S. Troop Readiness, Veterans' Care, Katrina Recovery, and Iraq Accountability Appropriations Act of 20072 (the Act). The Act requires GAO to report on the status of the achievement of these benchmarks. Consistent with GAO's core values and our desire to be fair and balanced, we also considered and used a "partially met" rating for some benchmarks. In comparison, the Act requires the administration to report on whether satisfactory progress is being made toward meeting the benchmarks. The benchmarks cover Iraqi government actions needed to advance reconciliation within Iraqi society, improve the security of the Iraqi population, provide essential services to the population, and promote economic well-being. To complete this work, we reviewed U.S. agency and Iraqi documents and interviewed officials from the Departments of Defense, State, and the Treasury; the Multi-National Force-Iraq (MNF-I) and its subordinate commands; the Defense Intelligence Agency; the Central Intelligence Agency; the National Intelligence Council; and the United Nations. These officials included Ryan Crocker, the U.S. Ambassador to Iraq, and General …

Medical Devices: Status of FDA's Program for Inspections by Accredited Organizations
A letter report issued by the Government Accountability Office with an abstract that begins "The Food and Drug Administration (FDA) inspects domestic and foreign establishments where U.S.-marketed medical devices are manufactured to assess compliance with FDA's quality system requirements for ensuring good manufacturing practices and other applicable requirements. The Medical Device User Fee and Modernization Act of 2002 (MDUFMA) required FDA to accredit organizations to inspect certain establishments where devices that are marketed in both the United States and other countries are manufactured. This report includes information that MDUFMA requires GAO to provide on (1) the number of organizations that sought accreditation, the number that were accredited, and reasons for denial of accreditation and (2) the number of inspections conducted by accredited organizations. It also includes information about factors that could influence manufacturers' interest in voluntarily requesting and paying for an inspection by an accredited organization. GAO examined FDA documents, interviewed FDA officials, and obtained information from FDA on the number of inspections conducted from March 11, 2004--when FDA first cleared an accredited organization to conduct independent inspections--through October 31, 2006. GAO also interviewed affected entities, including accredited organizations and medical device manufacturers."

Taxpayer Service: State Experiences Indicate IRS Would Face Challenges Developing an Internet Filing System with Net Benefits
A letter report issued by the Government Accountability Office with an abstract that begins "Some states and countries allow taxpayers to prepare and file tax returns on their Internet Web sites at no charge, an option not available to federal taxpayers. Such a service might mitigate the concerns taxpayers have about current electronic filing options, which require filing through a third party and may involve fees. Increased electronic filing would reduce IRS's paper processing costs, reduce transcription errors, and speed up refunds. However, the idea is controversial. IRS already has a Free File program which offers free return preparation and filing by private companies for some people via IRS's Web site. Some are opposed to IRS competing with tax preparation software companies. GAO was asked to (1) describe IRS's options for on-line preparation and filing (I-file) based on states' experiences; (2) determine the benefits and costs of I-file based on the experiences of the states; and (3) describe the potential for IRS to realize cost savings from I-file. GAO profiled 7 states and the District of Columbia, 2 foreign countries and 3 federal agencies to describe I-file options and determine their benefits and costs."

Defense Acquisitions: DOD's Research and Development Budget Requests to Congress Do Not Provide Consistent, Complete, and Clear Information
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) asked Congress for $73.2 billion in fiscal year 2007 for research, development, testing, and evaluation (RDT&E). DOD organized this request using program element (PE) codes, which are designed to convey key information about the budget request. DOD also provides documents called budget exhibits detailing the activities for which funds are being requested. The National Defense Authorization Act for Fiscal Year 2006 mandated that GAO examine the program elements and budget exhibits. GAO assessed (1) whether the RDT&E program element code structure and the associated budget exhibits provide accurate, consistent, complete, and clear information, and (2) what factors contribute to any problems found. In conducting this review GAO analyzed all of the fiscal year 2007 program element codes and 47 budget exhibits. GAO also interviewed key DOD officials."

Transition energy correlations in the three-body continuum of Borromean halo nuclei
Energy correlations in transitions from the bound state to the three-body continuum of Borromean halo nuclei are considered. A core+n+n three-body cluster model which reproduces experimentally known properties of {sup 6}He and {sup 11}Li has been used to study low-lying resonances and soft modes. The analysis of the correlated responses in {sup 6}He shows that in the case of the narrow three-body 2{sub 1}{sup +} resonance the transition energy correlations are the same as in the intrinsic correlated structure in 3 {yields} 3 scattering. They differ significantly for wide 2{sub 2}{sup +}, 1{sub 1}{sup +} resonances, and also for the soft dipole and monopole modes, where, due to the transition operators, the intertwining of the ground state and the three-body continuum plays a significant role.

The Emma Commissioning Procedure
The author begins with a brief review of the goals of the EMMA experiment. He then describe two stages of EMMA commissioning. The first stage is simply to get the beam to circulate a full turn in the ring, and is done only once during the course of the experiment. The second stage will be repeated several times, at least once for each lattice configuration, and involves two parts: setting the required values for the machine parameters, and determining the tunes and time of flight as a function of energy.

Non-destructive Identification of Individual Leukemia Cells by Optical Trapping Raman Spectroscopy
Currently, a combination of technologies is typically required to assess the malignancy of cancer cells. These methods often lack the specificity and sensitivity necessary for early, accurate diagnosis. Here we demonstrate using clinical samples the application of laser trapping Raman spectroscopy as a novel approach that provides intrinsic biochemical markers for the noninvasive detection of individual cancer cells. The Raman spectra of live, hematopoietic cells provide reliable molecular fingerprints that reflect their biochemical composition and biology. Populations of normal T and B lymphocytes from four healthy individuals, and cells from three leukemia patients were analyzed, and multiple intrinsic Raman markers associated with DNA and protein vibrational modes have been identified that exhibit excellent discriminating power for cancer cell identification. A combination of two multivariate statistical methods, principal component analysis (PCA) and linear discriminant analysis (LDA), was used to confirm the significance of these markers for identifying cancer cells and classifying the data. The results indicate that, on average, 95% of the normal cells and 90% of the patient cells were accurately classified into their respective cell types. We also provide evidence that these markers are unique to cancer cells and not purely a function of differences in their cellular activation.

Developing Poultry Facility Type Information from USDA Agricultural Census Data for Use in Epidemiological and Economic Models
The epidemiological and economic modeling of poultry diseases requires knowing the size, location, and operational type of each poultry type operation within the US. At the present time, the only national database of poultry operations that is available to the general public is the USDA's 2002 Agricultural Census data, published by the National Agricultural Statistics Service, herein referred to as the 'NASS data'. The NASS data provides census data at the county level on poultry operations for various operation types (i.e., layers, broilers, turkeys, ducks, geese). However, the number of farms and sizes of farms for the various types are not independent since some facilities have more than one type of operation. Furthermore, some data on the number of birds represents the number sold, which does not represent the number of birds present at any given time. In addition, any data tabulated by NASS that could identify numbers of birds or other data reported by an individual respondent is suppressed by NASS and coded with a 'D'. To be useful for epidemiological and economic modeling, the NASS data must be converted into a unique set of facility types (farms having similar operational characteristics). The unique set must not double count …

A HAMILTONIAN FORMULATION FOR SPIRAL-SECTOR ACCELERATORS.
I develop a formulation for Hamiltonian dynamics in an accelerator with magnets whose edges follow a spiral. I demonstrate using this Hamiltonian that a spiral FFAG can be made perfectly 'scaling'. I examine the effect of tilting an RF cavity with respect a radial line from the center of the machine, potentially with a different angle than the spiral of the magnets.

Biosynthesis of a Fully Functional Cyclotide inside Living Bacterial Cells
The cyclotide MCoTI-II is a powerful trypsin inhibitor recently isolated from the seeds of Momordica cochinchinensis, a plant member of cucurbitaceae family. We report for the first time the in vivo biosynthesis of natively-folded MCoTI-II inside live E. coli cells. Our biomimetic approach involves the intracellular backbone cyclization of a linear cyclotide-intein fusion precursor mediated by a modified protein splicing domain. The cyclized peptide then spontaneously folds into its native conformation. The use of genetically engineered E. coli cells containing mutations in the glutathione and thioredoxin reductase genes considerably improves the production of folded MCoTI-II in vivo. Biochemical and structural characterization of the recombinant MCoTI-II confirmed its identity. Biosynthetic access to correctly-folded cyclotides allows the possibility of generating cell-based combinatorial libraries that can be screened inside living cells for their ability to modulate or inhibit cellular processes.

Ionization efficiency studies for xenon ions with thesuperconducting ECR ion source VENUS
Ionization efficiency studies for high charge state xenon ions using a calibrated gas leak are presented. A 75% enriched {sup 129}Xe gas leak with a gas flow equivalent to 5.11p{mu}A was used in all the measurements. The experiments were performed at the VENUS (Versatile ECR ion source for Nuclear Science) ion source for 18 GHz, 28 GHz and double frequency operation. Overall, total ionization efficiencies close to 100% and ionization efficiencies into a single charge state up to 22% were measured. The influence of the biased disk on the ionization efficiency was studied and the results were somewhat surprising. When the biased disk was removed from the plasma chamber, the ionization efficiency was dramatically reduced for single frequency operation. However, using double frequency heating the ionization efficiencies achieved without the biased disk almost matched the ionization efficiencies achieved with the biased probe. In addition, we have studied the influence of the support gas on the charge state distribution of the xenon ions. Either pure oxygen or a mixture of oxygen and helium were used as support gases. The addition of a small amount of helium can increase the ionization efficiency into a single charge state by narrowing the charge state …

Energetics of Multiple-Ion Species Hohlraum Plasmas
A study of the laser-plasma interaction processes in multiple-ion species plasmas has been performed in plasmas that are created to emulate the plasma conditions in indirect drive inertial confinement fusion targets. Gas-filled hohlraums with densities of xe22/cc are heated to Te=3keV and backscattered laser light is measured by a suite of absolutely calibrated backscatter diagnostics. Ion Landau damping is increased by adding hydrogen to the CO2/CF4 gas fill. We find that the backscatter from stimulated Brillouin scattering is reduced is monotonically reduced with increasing damping, demonstrating that Landau damping is the controlling damping mechanism in ICF relevant high-electron temperature plasmas. The reduction in backscatter is accompanied by a comparable increase in both transmission of a probe beam and an increased hohlraum radiation temperature, showing that multiple-ion species plasmas improve the overall hohlraum energetics/performance. Comparison of the experimental data to linear gain calculations as well as detailed full-scale 3D laser-plasma interaction simulations show quantitative agreement. Our findings confirm the importance of Landau damping in controlling backscatter from high-electron temperature hohlraum plasmas and have lead to the inclusion of multi-ion species plasmas in the hohlraum point design for upcoming ignition campaigns at the National Ignition Facility.

Probing degradation in complex engineering silicones by 1H multiple quantum NMR
Static {sup 1}H Multiple Quantum Nuclear Magnetic Resonance (MQ NMR) has recently been shown to provide detailed insight into the network structure of pristine silicon based polymer systems. The MQ NMR method characterizes the residual dipolar couplings of the silicon chains that depend on the average molecular weight between physical or chemical constraints. Recently, we have employed MQ NMR methods to characterize the changes in network structure in a series of complex silicone materials subject to numerous degradation mechanisms, including thermal, radiative, and desiccative. For thermal degradation, MQ NMR shows that a combination of crosslinking due to post-curing reactions as well as random chain scissioning reactions occurs. For radiative degradation, the primary mechanisms are via crosslinking both in the network and at the interface between the polymer and the inorganic filler. For samples stored in highly desiccating environments, MQ NMR shows that the average segmental dynamics are slowed due to increased interactions between the filler and the network polymer chains.

COMPARISON OF RESPONSE OF 9977 TEST PACKAGES TO ANALYTICAL RESULTS
Each of the hypothetical accident test cases for the 9977 prototypes was included in the battery of finite element structural analyses performed for the package. Comparison of the experimental and analytical results provides a means of confirming that the analytical model correctly represents the physical behavior of the package. The ability of the analytical model to correctly predict the performance of the foam overpack material for the crush test is of particular interest. The dissipation of energy in the crushing process determines the deceleration of the package upon impact and the duration of the impact. In addition, if the analytical model correctly models the foam behavior, the predicted deformation of the package will match that measured on the test articles. This study compares the deformations of the test packages with the analytical predictions. In addition, the impact acceleration and impact duration for the test articles are compared with those predicted by the analyses.

Protein Microarrays--Without a Trace
Many experimental approaches in biology and biophysics, as well as applications in diagnosis and drug discovery, require proteins to be immobilized on solid supports. Protein microarrays, for example, provide a high-throughput format to study biomolecular interactions. The technique employed for protein immobilization is a key to the success of these applications. Recent biochemical developments are allowing, for the first time, the selective and traceless immobilization of proteins generated by cell-free systems without the need for purification and/or reconcentration prior to the immobilization step.
