ATLAS TrackingEvent Data Model -- 12.0.0
In this report the event data model (EDM) relevant for tracking in the ATLAS experiment is presented. The core component of the tracking EDM is a common track object which is suited to describe tracks in the innermost tracking sub-detectors and in the muon detectors in offline as well as online reconstruction. The design of the EDM was driven by a demand for modularity and extensibility while taking into account the different requirements of the clients. The structure of the track object and the representation of the tracking-relevant information are described in detail.

Geometrically induced metastability and holography
We construct metastable configurations of branes and anti-branes wrapping 2-spheres inside local Calabi-Yau manifolds and study their large N duals. These duals are Calabi-Yau manifolds in which the wrapped 2-spheres have been replaced by 3-spheres with flux through them, and supersymmetry is spontaneously broken. The geometry of the non-supersymmetric vacuum is exactly calculable to all orders of the't Hooft parameter, and to the leading order in 1/N. The computation utilizes the same matrix model techniques that were used in the supersymmetric context. This provides a novel mechanism for breaking supersymmetry in the context of flux compactifications.

Project Work Plan Chromium Vadose Zone Characterization and Geochemistry
The major objectives of the proposed study are to 1) determine the leaching characteristics of Cr(VI) from contaminated sediments collected from 100 area spill sites, 2) elucidate possible Cr(VI) mineral and/or chemical associations that may be responsible for Cr(VI) retention in the Hanford site 100 areas through the use of i) macroscopic solubility studies and ii) microscale characterization of contaminated sediments, and 3) from these data construct a conceptual model of Cr(VI) geochemistry in the Hanford 100 area vadose zone. These objectives are based on locating and obtaining contaminated sediment with depth and at varying Cr(VI) concentrations as we hypothesize that mineral/chemical-Cr(VI) associations should be related to the total Cr concentration and other master geochemical variables (e.g., pH, counter-cation type and concentration, and water content). In addressing these objectives, additional benefits accrued will be (1) a fuller understanding of Cr(VI) entrained in the vadose zone that will that can be utilized in modeling potential Cr(VI) source terms, and 2) accelerating the Columbia River 100 area corridor cleanup by developing remedial action based on a fundamental understanding of Cr(VI) vadose zone geochemistry.

A Review of Hazardous Chemical Species Associated with CO2 Capture from Coal-Fired Power Plants and Their Potential Fate in CO2 GeologicStorage
Conventional coal-burning power plants are major contributors of excess CO2 to the atmospheric inventory. Because such plants are stationary, they are particularly amenable to CO2 capture and disposal by deep injection into confined geologic formations. However, the energy penalty for CO2 separation and compression is steep, and could lead to a 30-40 percent reduction in useable power output. Integrated gas combined cycle (IGCC) plants are thermodynamically more efficient, i.e.,produce less CO2 for a given power output, and are more suitable for CO2 capture. Therefore, if CO2 capture and deep subsurface disposal were to be considered seriously, the preferred approach would be to build replacement IGCC plants with integrated CO2 capture, rather than retrofit existing conventional plants. Coal contains minor quantities of sulfur and nitrogen compounds, which are of concern, as their release into the atmosphere leads to the formation of urban ozone and acid rain, the destruction of stratospheric ozone, and global warming. Coal also contains many trace elements that are potentially hazardous to human health and the environment. During CO2 separation and capture, these constituents could inadvertently contaminate the separated CO2 and be co-injected. The concentrations and speciation of the co-injected contaminants would differ markedly, depending on whether CO2 …

Oral History Interview with James Atkinson, March 23, 2006
The National Museum of the Pacific War presents an oral interview with James E. Atkinson. Atkinson was born in Pine Bluff, Arkansas in 1921. His younger brother was killed in Europe during the war. Atkinson attended Vanderbilt University with a football scholarship in 1940. In 1942 he joined the Navy Reserves and entered the V-12 Navy College Training Program. Soon afterwards, he entered Midshipman’s school at Notre Dame. Upon graduating 20 June 1944, he was commissioned an ensign. He then entered submarine school at New London, Connecticut. He describes the characteristics of a fleet submarine. After completing four months of school, he flew to Brisbane, Australia and reported aboard the USS Flasher (SS-249). Atkinson served during the boat’s fourth, fifth and sixth combat patrols. He describes sinking two Japanese destroyers and four tankers. On the sixth combat patrol, they sank two Japanese ships and returned to Pearl Harbor for overhaul in April 1945. Afterwards, the boat was at sea bound for Guam when the atomic bombs were dropped on Japan. Returning to New London, Connecticut, the crew decommissioned the boat.

Measurement of the B to pi l nu Branching Fraction and Determination of |Vub| with Tagged B Mesons
We report a measurement of the B {yields} {pi}{ell}{nu} branching fraction based on 211 fb{sup -1} of data collected with the BABAR detector. We use samples of B{sup 0} and B{sup +} mesons tagged by a second B meson reconstructed in a semileptonic or hadronic decay, and combine the results assuming isospin symmetry to obtain {Beta}(B{sup 0} {yields} {pi}{sup -}{ell}{sup +}{nu}) = (1.33 {+-} 0.17{sub stat} {+-} 0.11{sub syst}) x 10{sup -4}. We determine the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element |V{sub ub}| by combining the partial branching fractions measured in ranges of the momentum transfer squared and theoretical calculations of the form factor. Using a recent lattice QCD calculation, we find |{sub ub}| = (4.5 {+-} 0.5{sub stat} {+-} 0.3{sub syst} {sub -0.5}{sup +0.7}FF) x 10{sup -3}, where the last error is due to the normalization of the form factor.

Measurement of the CP Asymmetry and BranchingFraction of B^0 to \rho^{0}K^0
The authors present a measurement of the branching fraction and time-dependent CP asymmetry of B{sup 0} {yields} {rho}{sup 0}K{sup 0}. The results are obtained from a data sample of 227 x 10{sup 6} {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. From a time-dependent maximum likelihood fit yielding 111 {+-} 19 signal events they find {Beta}(B{sup 0} {yields} {rho}{sup 0}K{sup 0}) = (4.9 {+-} 0.8 {+-} 0.9) x 10{sup -6}, where the first error is statistical and the second systematic. They report the measurement of the CP parameters S{sub {rho}{sup 0}K{sub S}{sup 0}} = 0.20 {+-} 0.52 {+-} 0.24 and C{sub {rho}{sup 0}K{sub S}{sup 0}} = 0.64 {+-} 0.41 {+-} 0.20.

Measurements of CP-Violating Asymmetries and BranchingFractions in B Decays to omegaK and omegaPi
We present measurements of CP-violating asymmetries and branching fractions for the decays B{sup +} {yields} {omega}{pi}{sup +}, B{sup +} {yields} {omega}K{sup +}, and B{sup 0} {yields} {omega}K{sup 0}. The data sample corresponds to 232 million B{bar B} pairs produced by e{sup +}e{sup -} annihilation at the {Upsilon}(4S) resonance. For the decay B{sup 0} {yields} {omega}K{sub s}{sup 0}, we measure the time-dependent CP-violation parameters S = 0.51{sub -0.39}{sup +0.35} {+-} 0.02, and C = -0.55{sub -0.26}{sup +0.28} {+-} 0.03. We also measure the branching fractions, in units of 10{sup -6}, {Beta}(B{sup +} {yields} {omega}{pi}{sup +}) = 6.1 {+-} 0.7 {+-} 0.4, {Beta}(B{sup +} {yields} {omega}K{sup +}) = 6.1 {+-} 0.6 {+-} 0.4, and {Beta}(B{sup 0} {yields} {omega}K{sup 0}) = 6.2 {+-} 1.0 {+-} 0.4, and charge asymmetries {Alpha}{sub ch}(B{sup +} {yields} {omega}{pi}{sup +}) = -0.01 {+-} 0.10 {+-} 0.01 and {Alpha}{sub ch}(B{sup +} {yields} {omega}K{sup +}) = 0.05 {+-} 0.09 {+-} 0.01.

Structural health monitoring of wind turbine blades : SE 265 Final Project.
ACME Wind Turbine Corporation has contacted our dynamic analysis firm regarding structural health monitoring of their wind turbine blades. ACME has had several failures in previous years. Examples are shown in Figure 1. These failures have resulted in economic loss for the company due to down time of the turbines (lost revenue) and repair costs. Blade failures can occur in several modes, which may depend on the type of construction and load history. Cracking and delamination are some typical modes of blade failure. ACME warranties its turbines and wishes to decrease the number of blade failures they have to repair and replace. The company wishes to implement a real time structural health monitoring system in order to better understand when blade replacement is necessary. Because of warranty costs incurred to date, ACME is interested in either changing the warranty period for the blades in question or predicting imminent failure before it occurs. ACME's current practice is to increase the number of physical inspections when blades are approaching the end of their fatigue lives. Implementation of an in situ monitoring system would eliminate or greatly reduce the need for such physical inspections. Another benefit of such a monitoring system is that …
