Oil and Gas Royalties: The Federal System for Collecting Oil and Gas Revenues Needs Comprehensive Reassessment

Description: A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2007, domestic and foreign companies received over $75 billion from the sale of oil and gas produced from federal lands and waters, according to the Department of the Interior (Interior), and these companies paid the federal government about $9 billion in royalties for this oil and gas production. The government also collects other revenues in rents, taxes, and other fees, and the sum of … more

How to Calculate Colourful Cross Sections Efficiently

Description: Different methods for the calculation of cross sections with many QCD particles are compared. To this end, CSW vertex rules, Berends-Giele recursion and Feynman-diagram based techniques are implemented as well as various methods for the treatment of colours and phase space integration. We find that typically there is only a small window of jet multiplicities, where the CSW technique has efficiencies comparable or better than both of the other two methods.

Comix, a New Matrix Element Generator

Description: We present a new tree-level matrix element generator, based on the color dressed Berends-Giele recursive relations. We discuss two new algorithms for phase space integration, dedicated to be used with large multiplicities and color sampling.

TRWG developmental pathway for biospecimen-based assessment modalities

Description: The Translational Research Working Group (TRWG) was created as a national initiative to evaluate the current status of NCI's investment in translational research and envision its future. The TRWG conceptualized translational research as a set of six developmental processes or pathways focused on various clinical goals. One of those pathways describes the development of biospecimen-based assays that utilize biomarkers for the detection, diagnosis, prognosis, and assessment of response to cancer … more

International Linear Collider Accelerator Physics R&D

Description: ILC work at Illinois has concentrated primarily on technical issues relating to the design of the accelerator. Because many of the problems to be resolved require a working knowledge of classical mechanics and electrodynamics, most of our research projects lend themselves well to the participation of undergraduate research assistants. The undergraduates in the group are scientists, not technicians, and find solutions to problems that, for example, have stumped PhD-level staff elsewhere. The ILC… more

Manifest Ultraviolet Behavior in the Three-Loop Four-Point Amplitude of N=8 Supergravity

Description: Using the method of maximal cuts, we obtain a form of the three-loop four-point scattering amplitude of N = 8 supergravity in which all ultraviolet cancellations are made manifest. The Feynman loop integrals that appear have a graphical representation with only cubic vertices, and numerator factors that are quadratic in the loop momenta, rather than quartic as in the previous form. This quadratic behavior reflects cancellations beyond those required for finiteness, and matches the quadratic beh… more

Search for Second-Class Currents in \tau^-\to\omega\pi^-\nu_{\tau}

Description: We report on an analysis of {tau}{sup -} decaying into {omega}{pi}{sup -}{nu}{sub {tau}} with {omega} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup 0} using data containing nearly 320 million tau pairs collected with the BABAR detector at the PEP-II asymmetric energy B-Factory. We find no evidence for second-class currents and set an upper limit at 0.69% at a 90% confidence level for the ratio of second- to first-class currents.

IMPACT simulation and the SNS linac beam

Description: Multi-particle tracking simulations for the SNS linac beam dynamics studies are performed with the IMPACT code. Beam measurement results are compared with the computer simulations, including beam longitudinal halo and beam losses in the superconducting linac, transverse beam Courant-Snyder parameters and the longitudinal beam emittance in the linac. In most cases, the simulations show good agreement with the measured results.

Development of Polybenzimidazole-Based High-Temperature Membrane and Electrode Assemblies for Stationary and Automotive Applications

Description: The program began on August 1, 2003 and ended on July 31, 2007. The goal of the project was to optimize a high-temperature polybenzimidazole (PBI) membrane to meet the performance, durability, and cost targets required for stationary fuel cell applications. These targets were identified in the Fuel Cell section (3.4) of DOE’s Hydrogen, Fuel Cells and Infrastructure Technologies Program Multi-Year Research, Development and Demonstration Plan. A membrane that operates at high temperatures is impo… more

Amplitude Analysis of the Decay B0->K+pi-pi0

Description: We report an updated amplitude analysis of the charmless hadronic decays of neutral B mesons to K{sup +} {pi}{sup -}{pi}{sup 0}. With a sample of 454 million {Upsilon}(4S) {yields} B{bar B} decays collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC, we measure the magnitudes and phases of the intermediate resonant and nonresonant amplitudes for B{sup 0} and B{sup 0} decays and determine the corresponding CP-averaged fit fractions and charge asymmetries.

Health Insurance Coverage: Characteristics of the Insured and Uninsured Populations in 2007

Description: Based on data from the Census Bureau’s Current Population Survey (CPS), 45.7 million people in the United States had no health insurance in 2007 — a decrease of approximately 1.3 million people when compared with 2006. This report briefly examines the characteristics of this uninsured population.

Gradual Ordering in Red Abalone Nacre

Description: Red abalone (Haliotis rufescens) nacre is a layered composite biomineral that contains crystalline aragonite tablets confined by organic layers. Nacre is intensely studied because its biologically controlled microarchitecture gives rise to remarkable strength and toughness, but the mechanisms leading to its formation are not well understood. Here we present synchrotron spectromicroscopy experiments revealing that stacks of aragonite tablet crystals in nacre are misoriented with respect to each … more

Congressional Review Act: Disapproval of Rules in a Subsequent Session of Congress

Description: This report addresses some of the implications of the CRA with regard to agency rulemaking in the final months of a presidential administration. It first notes the practice of increased rulemaking activity during this period, and describes how this practice has been addressed by two White House memoranda issued during the current Bush Administration. The report then briefly identifies key elements of the complex set of time periods established by the CRA — elements that define points during the… more
