Elections: Further Testing Could Provide Increased but Not Absolute Assurance That Voting Systems Did Not Cause Undervotes in Florida's 13th Congressional District
A statement of record issued by the Government Accountability Office with an abstract that begins "In November 2006, about 18,000 undervotes were reported in Sarasota County in the race for Florida's 13th Congressional District (FL-13). After the contesting of the election results in the House of Representatives, the task force unanimously voted to seek GAO's assistance in determining whether the voting systems contributed to the large undervote in Sarasota County. GAO agreed with the task force on an engagement plan, including the following review objectives: (1) What voting systems were used in Sarasota County and what processes governed their use? (2) What was the scope of the undervote in Sarasota County in the general election? (3) What tests were conducted on the voting systems in Sarasota County prior to the general election and what were the results of those tests? (4) Considering the voting systems tests conducted after the general election, are additional tests needed to determine whether the voting systems contributed to the undervote? To conduct its work, GAO met with officials from the State of Florida, Sarasota County, and Election Systems and Software (ES&S)--the voting systems manufacturer--and reviewed voting systems test documentation. GAO analyzed election data to characterize …

Indian Issues: Spokane Tribe's Additional Compensation Claim for the Grand Coulee Dam
A statement of record issued by the General Accounting Office with an abstract that begins "The Grand Coulee Dam was constructed on the Columbia River in northeastern Washington State from 1933 to 1942. The reservoir behind the dam covers land on the Colville Reservation along the Columbia River and land on the adjacent Spokane Reservation along both the Columbia and Spokane rivers. Under a 1940 act, the federal government paid $63,000 and $4,700 to the Colville and Spokane tribes, respectively, for the land used for the dam and reservoir. Subsequently, the Colville tribes pursued additional claims for their lost fisheries and for "water power values" and in 1994 were awarded a lump sum payment of $53 million and, beginning in 1996, annual payments that have ranged between $14 million to $21 million. The Spokane tribe is currently pursuing similar claims. S. 1438, introduced in July 2003, is a proposed legislative settlement for the Spokane tribe's claims. While settlement proposals introduced in the 106th and 107th Congresses directed the settlement costs to be split between Bonneville and the Treasury, S. 1438 provides that the settlement be paid entirely from the Treasury. This statement for the record addresses the (1) impact of …

Foreign Assistance: U.S. Russia Fund Is Following Its Investment Selection Process and Criteria
A letter report issued by the General Accounting Office with an abstract that begins "This report summarizes GAO's findings on the United States Russia Fund and its investment selection process and criteria. The United States established enterprise funds to support private sector development in Central and Eastern Europe and the former Soviet Union as they move from centrally planned to market-oriented economies. Enterprise funds are private, nonprofit U.S. corporations that are supposed to make loans to, or invest in, small, medium, and large businesses in which other financial institutions are reluctant to invest. The Fund is authorized to receive $440 million through the Agency for International Development. As of March 2000, the Fund had invested $114.4 million in 30 projects through its direct investment program which provides loans and equity capital to businesses in Russia. GAO found that the Fund followed its review process and criteria for selecting direct investments."

Commercial Aviation: Financial Condition and Industry Responses Affect Competition
Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the economic state of the airline industry. Many, but not all, major U.S. passenger airlines are experiencing their second consecutive year of record financial losses. In 2001, the U.S. commercial passenger airline industry reported losses in excess of $6 billion. For 2002, some Wall Street analysts recently projected that U.S. airline industry losses will approach $7 billion, and noted that the prospects for recovery during 2003 are diminishing. Carriers have taken many actions to lower their costs and restructure their operations. Since September 2001, carriers have furloughed 100,000 staff, renegotiated labor contracts, and streamlined their fleets by retiring older, costlier aircraft. Carriers have reduced capacity by operating fewer flights or smaller aircraft. In some cases, carriers eliminated all service to communities. As the aviation industry continues its attempts to recover, Congress will be confronted with a need for increased oversight of a number of public policy issues. First, airlines' reactions to financial pressures will affect the domestic industry's competitive landscape. Second, airlines' reductions in service will likely place additional pressure on federal programs supporting air service to small communities, where travel options are already limited. …

Foreign Assistance: USAID Compliance With Family Planning Restrictions
A letter report issued by the General Accounting Office with an abstract that begins "The United States has provided international family planning assistance through the Agency for International Development (AID) since the mid-1960s. U.S. law prohibits the use of international family planning funds for abortions and requires that all family planning programs supported by AID be voluntary. This report discusses: (1) how much family planning assistance AID provided in fiscal years 1996-1999 and plans to provide in fiscal year 2000, and (2) what procedures have been established to ensure that funds are not being used for prohibited activities. GAO found that AID provided $432 million in assistance in fiscal year 1996 and $385 million in each of fiscal years 1997-1999. AID has established multiple procedures to ensure that family planning funds are not used for prohibited activities, including specifying the restrictions in grants, contracts, and cooperative agreements."

Federal Emergency Management Agency: Ongoing Challenges Facing the National Flood Insurance Program
Testimony issued by the Government Accountability Office with an abstract that begins "The National Flood Insurance Program (NFIP), established in 1968, provides property owners with some insurance coverage for flood damage. The Federal Emergency Management Agency (FEMA) within the Department of Homeland Security is responsible for managing the NFIP. Given the challenges facing the NFIP and the need for legislative reform to ensure the financial stability and ongoing viability of this program, GAO placed the NFIP on its high-risk list in March 2006. This testimony updates past work and provides information about ongoing GAO work on issues including (1) NFIP's financial structure, (2) the extent of compliance with mandatory requirements, (3) the status of map modernization efforts, and (4) FEMA's oversight of the NFIP. Building on our previous and ongoing work on the NFIP, GAO collected data from FEMA to update efforts, including information about claims, policies, repetitive loss properties, and mitigation efforts."

Electronic Government: Opportunities and Challenges Facing the FirstGov Web Gateway
Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses what can be accomplished with FirstGov.gov and identifies challenges that should be addressed as it continues to be developed and refined. Under FirstGov, an important and previously unavailable capability--searching the entire government's web pages--was rapidly and successfully put into place. The FirstGov Board of Directors needs to address the following four issues: (1) improving site security, (2) assessing and acting upon information in the Fed-Search database that might facilitate malicious activity, (3) addressing issues regarding private sector sponsorship, and (4) developing plans for the future. An overall management plan for FirstGov.gov would be a useful vehicle for setting expectations about what general functions are likely to be achievable for FirstGov in the near term, how the site will be managed on an ongoing basis, and how progress toward the larger goals set forth in the President's December 1999 memorandum will be measured."

Contract Management: Restructuring GSA's Federal Supply Service and Federal Technology Service
Testimony issued by the General Accounting Office with an abstract that begins "The General Services Administration's (GSA) Federal Supply Service (FSS) and Federal Technology Service (FTS) play an important role in assisting agencies procure a wide range of products and services. Over the past several years, FSS and FTS purchases have significantly increased, with IT products and services being the primary source of this growth. In April 2002, we identified overlap in FSS' and FTS' IT procurement programs. A management consultant similarly found overlaps in FTS' and FSS' IT sales and marketing functions and contract offerings. To enhance FSS and FTS operational efficiency and effectiveness--in both its IT and non-IT business lines--GSA has undertaken a performance improvement initiative. This testimony focuses on GSA's actions to implement its initiative. It also discusses the importance of enhancing GSA's ability to help agencies strategically purchase products and services."

Elastic and transport properties in polycrystals of crackedgrains: Cross-property relations and microstructure
Some arguments of Bristow (1960) concerning the effects of cracks on elastic and transport (i.e., electrical or thermal conduction) properties of cold-worked metals are reexamined. The discussion is posed in terms of a modern understanding of bounds and estimates for physical properties of polycrystals--in contrast to Bristow's approach using simple mixture theory. One type of specialized result emphasized here is the cross-property estimates and bounds that can be obtained using the methods presented. Our results ultimately agree with those of Bristow, i.e., confirming that microcracking is not likely to be the main cause of the observed elastic behavior of cold-worked metals. However, it also becomes clear that the mixture theory approach to the analysis is too simple and that crack-crack interactions are necessary for proper quantitative study of Bristow's problem.

Effect of Background Emissivity on Gas Detection in Thermal Hyperspectral Imagery
Detecting and identifying weak gaseous plumes using thermal imaging data is complicated by many factors. These include variability due to atmosphere, ground and plume temper- ature, and background clutter. This paper presents an analysis of one formulation of the physics-based radiance model, which describes at-sensor observed radiance. The background emissivity and plume/ground temperatures are isolated, and their effects on net chemical signal are described. This analysis shows that the plume’s physical state, emission or absorption, is directly dependent on the background emissivity. It then describes what conditions on the background emissivity have inhibiting effects on the net chemical signal. These claims are illustrated by analyzing synthetic hyperspectral imaging data with the Adaptive Matched Filter using four chemicals and three distinct background emissivities. Two chemicals (Carbontetrachloride and Tetraflourosilane) in the analysis had a very strong relationship with the background emissivities: they exhibited absorbance over a small range of wavenumbers and the background emissivities showed a consistent ordering at these wavenumbers. Analysis of simulated hyperspectral images containing these chemicals showed complete agreement with the analysis of the physics-based model that described when the background emissivities would have inhibiting effects on gas detection. The other chemicals considered (Ammonia and Tributylphosphate) exhibited very complex …

DiMES Studies of Temperature Dependence of Carbon Erosion and Re-Deposition in the DIII-D Divertor
A strong effect of a moderately elevated surface temperature on net carbon deposition and deuterium co-deposition in the DIII-D divertor was observed under detached conditions. A DiMES sample with a gap 2 mm wide and 18 mm deep was exposed to lower-single-null (LSN) L-mode plasmas first at room temperature, and then at 200 C. At the elevated temperature, deuterium co-deposition in the gap was reduced by an order of magnitude. At the plasma-facing surface of the heated sample net carbon erosion was measured at a rate of 3 nm/s, whereas without heating net deposition is normally observed under detachment. In a related experiment three sets of molybdenum mirrors recessed 2 cm below the divertor floor were exposed to identical LSN ELMy H-mode discharges. The first set of mirrors exposed at ambient temperature exhibited net carbon deposition at a rate of up to 3.7 nm/s and suffered a significant drop in reflectivity. In contrast, two other mirror sets exposed at elevated temperatures between 90 C and 175 C exhibited virtually no carbon deposition.

Introduction to Electroweak Symmetry Breaking
The Standard Model (SM) is the backbone of elementary particle physics-not only does it provide a consistent framework for studying the interactions of quark and leptons, but it also gives predictions which have been extensively tested experimentally. In these notes, I review the electroweak sector of the Standard Model, discuss the calculation of electroweak radiative corrections to observables, and summarize the status of SM Higgs boson searches. Despite the impressive experimental successes, however, the electroweak theory is not completely satisfactory and the mechanism of electroweak symmetry breaking is untested. I will discuss the logic behind the oft-repeated statement: 'There must be new physics at the TeV scale'. These lectures reflect my strongly held belief that upcoming results from the LHC will fundamentally change our understanding of electroweak symmetry breaking. In these lectures, I review the status of the electroweak sector of the Standard Model, with an emphasis on the importance of radiative corrections and searches for the Standard Model Higgs boson. A discussion of the special role of the TeV energy scale in electroweak physics is included.

Measurement of Transverse Single-Spin Asymmetries for Di-JetProduction in Proton-Proton Collisions at sqrt s = 200 GeV
We report the first measurement of the opening angledistribution between pairs of jets produced in high-energy collisions oftransversely polarized protons. The measurement probes (Sivers)correlations between the transverse spin orientation of a proton and thetransverse momentum directions of its partons. With both beams polarized,the wide pseudorapidity (-1 leq eta leq +2) coverage for jets permitsseparation of Sivers functions for the valence and sea regions. Theresulting asymmetries are all consistent with zero and considerablysmaller than Sivers effects observed in semi-inclusive deep inelasticscattering (SIDIS). We discuss theoretical attempts to reconcile the newresults with the sizable transverse spin effects seen in SIDIS andforward hadron production in pp collisions.

Telomere dysfunction and cell survival: Roles for distinct TIN2-containing complexes
Telomeres are maintained by three DNA binding proteins (TRF1, TRF2 and POT1), and several associated factors. One factor, TIN2, binds TRF1 and TRF2 directly and POT1 indirectly. Along with two other proteins, TPP1 and hRap1, these form a soluble complex that may be the core telomere maintenance complex. It is not clear whether sub-complexes also exist in vivo. We provide evidence for two TIN2 sub-complexes with distinct functions in human cells. We isolated these two TIN2 sub-complexes from nuclear lysates of unperturbed cells and cells expressing TIN2 mutants TIN2-13, TIN2-15C, which cannot bind TRF2 or TRF1, respectively. In cells with wild-type p53 function, TIN2-15C was more potent than TIN2-13 in causing telomere uncapping and eventual growth arrest. In cells lacking p53 function, TIN2-15C was more potent than TIN2-13 in causing telomere dysfunction and cell death. Our findings suggest that distinct TIN2 complexes exist, and that TIN2-15C-sensitive subcomplexes are particularly important for cell survival in the absence of functional p53.

Toward a Mesoscale Model for the Dynamics of Polymer Solutions
To model entire microfluidic systems containing solvated polymers we argue that it is necessary to have a numerical stability constraint governed only by the advective CFL condition. Advancements in the treatment of Kramers bead-rod polymer models are presented to enable tightly-coupled fluid-particle algorithms in the context of system-level modeling.

Compton scattering measurements from dense plasmas
Compton scattering has been developed for accurate measurements of densities and temperatures in dense plasmas. One future challenge is the application of this technique to characterize compressed matter on the National Ignition Facility where hydrogen and beryllium will approach extremely dense states of matter of up to 1000 g/cc. In this regime, the density, compressibility, and capsule fuel adiabat may be directly measured from the Compton scattered spectrum of a high-energy x-ray line source. Specifically, the scattered spectra directly reflect the electron velocity distribution. In non-degenerate plasmas, the width provides an accurate measure of the electron temperatures, while in partially Fermi degenerate systems that occur in laser-compressed matter it provides the Fermi energy and hence the electron density. Both of these regimes have been accessed in experiments at the Omega laser by employing isochorically heated solid-density beryllium and moderately compressed beryllium foil targets. In the latter experiment, compressions by a factor of 3 at pressures of 40 Mbar have been measured in excellent agreement with radiation hydrodynamic modeling.

MAXIMA-1: A Measurement of the Cosmic Microwave Background Anisotropy on Angular Scales of 10' to 5 Degrees
We present a map and an angular power spectrum of the anisotropy of the cosmic microwave background (CMB) from the first flight of MAXIMA. MAXIMA is a balloon-borne experiment with an array of 16 bolometric photometers operated at 100 mK. MAXIMA observed a 124 deg region of the sky with 10' resolution at frequencies of 150, 240 and 410 GHz. The data were calibrated using in-flight measurements of the CMB dipole anisotropy. A map of the CMB anisotropy was produced from three 150 and one 240 GHz photometer without need for foreground subtractions. Analysis of this CMB map yields a power spectrum for the CMB anisotropy over the range 36 {le} {ell} {le} 785. The spectrum shows a peak with an amplitude of 78 {+-} 6 {mu}K at {ell} {approx_equal} 220 and an amplitude varying between {approx} 40 {mu}K and {approx} 50 {mu}K for 400 {approx}< {ell} {approx}< 785.

The Genetically Remote Pathogenic Strain NVH391-98 of the Bacillus cereus Group Represents the Cluster of Thermophilic Strains
Bacteria of the Bacillus cereus group are known to cause food poisoning. A rare phylogenetically remote strain, NVH391-98, was recently characterized to encode a particularly efficient cytotoxin K presumably responsible for food poisoning. This pathogenic strain and its close relatives can be phenotypically distinguished from other strains of the B. cereus group by the inability to grow at temperatures below 17 degrees C and by the ability to grow at temperatures from 48 to 53 degrees C. A temperate phage, phBC391A2, residing in the genome of NVH391-98 allows us to distinguish the three known members of this thermophilic strain cluster.

Is Increased Low-dose somatic Radiosensitivity Associated with Increased Transgenerational Germline Mutation
Using single-molecule polymerase chain reaction, the frequency of spontaneous and radiation-induced mutation at an expanded simple tandem repeat (ESTR) locus was studied in DNA samples extracted from sperm and bone marrow of Atm knockout (Atm+/–) heterozygous male mice. The frequency of spontaneous mutation in sperm and bone marrow in Atm+/– males did not significantly differ from that in wild-type BALB/c mice. Acute gamma-ray exposure did not affect ESTR mutation frequency in bone marrow and resulted in similar increases in sperm samples taken from Atm+/– and BALB/c males. Taken together, these results suggest that the Atm haploinsufficiency analyzed in our study does not affect spontaneous and radiation-induced ESTR mutation frequency in mice.

Development of An On-Line, Core Power Distribution Monitoring System
The objective of the proposed work was to develop a software package that can construct in three-dimensional core power distributions using the signals from constant temperature power sensors distributed in the reactor core. The software developed uses a mode-based state/parameter estmation technique that is particularly attractive when there are model uncertainties and/or large signal noise. The software yields the expected value of local power at the detector locations and points in between, as well as the probability distribution of the local power density
