Critical issues in the formation of quantum computer test structures by ion implantation (open access)

Critical issues in the formation of quantum computer test structures by ion implantation

The formation of quantum computer test structures in silicon by ion implantation enables the characterization of spin readout mechanisms with ensembles of dopant atoms and the development of single atom devices. We briefly review recent results in the characterization of spin dependent transport and single ion doping and then discuss the diffusion and segregation behaviour of phosphorus, antimony and bismuth ions from low fluence, low energy implantations as characterized through depth profiling by secondary ion mass spectrometry (SIMS). Both phosphorus and bismuth are found to segregate to the SiO2/Si interface during activation anneals, while antimony diffusion is found to be minimal. An effect of the ion charge state on the range of antimony ions, 121Sb25+, in SiO2/Si is also discussed.

Insurance Reciprocity and Uniformity: NAIC and State Regulators Have Made Progress in Producer Licensing, Product Approval, and Market Conduct Regulation, but Challenges Remain (open access)

Insurance Reciprocity and Uniformity: NAIC and State Regulators Have Made Progress in Producer Licensing, Product Approval, and Market Conduct Regulation, but Challenges Remain

A letter report issued by the Government Accountability Office with an abstract that begins "Because the insurance market is a vital part of the U.S. economy, Congress and others are concerned about limitations to reciprocity and uniformity, regulatory inefficiency, higher insurance costs, and uneven consumer protection. GAO was asked to review the areas of (1) producer licensing, (2) product approval, and (3) market conduct regulation in terms of progress by NAIC and state regulators to increase reciprocity and uniformity, the factors affecting this progress, and the potential impacts if greater progress is not made. GAO analyzed federal laws and regulatory documents, assessed NAIC efforts, and interviewed industry officials."

MOLECULAR DESIGN OF COLLOIDS IN SUPERCRITICAL FLUIDS (open access)

MOLECULAR DESIGN OF COLLOIDS IN SUPERCRITICAL FLUIDS

The environmentally benign, non-toxic, non-flammable fluids water and carbon dioxide (CO2) are the two most abundant and inexpensive solvents on earth. Emulsions of these fluids are of interest in many industrial processes, as well as CO2 sequestration and enhanced oil recovery. Until recently, formation of these emulsions required stabilization with fluorinated surfactants, which are expensive and often not environmentally friendly. In this work we overcame this severe limitation by developing a fundamental understanding of the properties of surfactants the CO2-water interface and using this knowledge to design and characterize emulsions stabilized with either hydrocarbon-based surfactants or nanoparticle stabilizers. We also discovered a new concept of electrostatic stabilization for CO2-based emulsions and colloids. Finally, we were able to translate our earlier work on the synthesis of silicon and germanium nanocrystals and nanowires from high temperatures and pressures to lower temperatures and ambient pressure to make the chemistry much more accessible.

BaBar Status and Prospects for CP Asymmetry Measurements: Sin(2beta + gamma)

The recent experimental results on CP violation related to the angles of the Cabibbo-Kobayashi-Maskawa (CKM) unitarity triangle 2{beta} + {gamma} are summarized in these proceedings. These results are obtained with approximately 232 million {Upsilon}(4S) {yields} B{bar B} events collected with the BABAR detector at the PEP-II asymmetric-energy B-factory at SLAC. Using the measurements on time-dependent CP asymmetries in B{sup 0} {yields} D{sup (*){-+}} {pi}{sup {-+}} and B{sup 0} {yields} D{sup {-+}}{rho}{sup {+-}} decays and theoretical assumptions, one finds | sin(2{beta} + {gamma}) | > 0.64 (0.40) at 68% (90%) confidence level. The perspectives of sin(2{beta} + {gamma}) measurement with {bar B}{sup 0} {yields} D{sup (*)0} {bar K}{sup (*)0} and B{sup 0} {yields} D{sup (*){-+}}{alpha}{sub 0(2)}{sup {+-}} decay channels are also discussed.

Bankruptcy Reform: Value of Credit Counseling Requirement Is Not Clear (open access)

Bankruptcy Reform: Value of Credit Counseling Requirement Is Not Clear

A letter report issued by the Government Accountability Office with an abstract that begins "The Bankruptcy Abuse Prevention and Consumer Protection Act of 2005 requires individuals to receive credit counseling before filing for bankruptcy and to take a debtor education course before having debts discharged. Concerns were raised that the new requirements could expose consumers to abusive practices by credit counseling agencies or become barriers to filing for bankruptcy. GAO was asked to examine (1) the process of approving counseling and education providers, (2) the content and results of the counseling and education sessions, (3) the fees charged, and (4) the availability of and challenges to accessing services. To address these issues, GAO reviewed Trustee Program data and application case files, and interviewed a wide range of individuals and groups involved in the bankruptcy process."

Biomass-Derived Hydrogen from a Thermally Ballasted Gasifier (open access)

Biomass-Derived Hydrogen from a Thermally Ballasted Gasifier

The goal of this project is to develop an indirectly heated gasification system that converts switchgrass into hydrogen-rich gas suitable for powering fuel cells. The project includes investigations of the indirectly-heated gasifier, development of particulate removal equipment, evaluation of catalytic methods for upgrading producer gas, development of contaminant measurement and control techniques, modeling of the thermal performance of the ballasted gasifier, and estimation of the cost of hydrogen from the proposed gasification system. Specific technologies investigated include a thermally ballasted gasifier, a moving bed granular filter, and catalytic reactors for steam reforming and water-gas shift reaction. The approach to this project was to employ a pilot-scale (5 ton per day) gasifier to evaluate the thermally ballasted gasifier as a means for producing hydrogen from switchgrass. A slipstream from the gasifier was used to evaluate gas cleaning and upgrading options. Other tests were conducted with laboratory-scale equipment using simulated producer gas. The ballasted gasifier operated in conjunction with a steam reformer and two-stage water-gas shift reactor produced gas streams containing 54.5 vol-% H2. If purge gas to the feeder system could be substantially eliminated, hydrogen concentration would reach 61 vol-%, which closely approaches the theoretical maximum of 66 vol-%. Tests with …

Borehole Gravity Meter Surveys at the Waste Treatment Plant, Hanford, Washington. (open access)

Borehole Gravity Meter Surveys at the Waste Treatment Plant, Hanford, Washington.

Microg-LaCoste (MGL) was contracted by Pacfic Northwest National Laboratories (PNNL) to record borehole gravity density data in 3 wells at the HanfordWaste Treatment Plant (WTP) site. The survey was designed to provide highly accurate density information for use in seismic modeling. The borehole gravity meter (BHGM) tool has a very large depth of investigation (hundreds of feet) compared to other density tools so it is not influenced by casing or near welbore effects, such as washouts.

Clean Water Act and Total Maximum Daily Loads (TMDLs) of Pollutants (open access)

Clean Water Act and Total Maximum Daily Loads (TMDLs) of Pollutants

This report discusses the section 303(d) of the Clean Water Act, which requires states to identify waters that are impaired by pollution, even after application of pollution controls. For those waters, states must establish a total maximum daily load (TMDL) of pollutants to ensure that water quality standards can be attained. Implementation was dormant until states and EPA were prodded by lawsuits. The TMDL program has become controversial, in part because of requirements and costs now facing states to implement this 35-year-old provision of the law, as well as industries, cities, farmers, and others who may be required to use new pollution controls to meet TMDL requirements. In July 2000, EPA issued revisions to strengthen the program. The rule was widely criticized, and congressional interest was high. The 2000 rule did not go into effect, and in March 2003, EPA withdrew the rule to consider whether to issue an entirely new rule or other options; no timetable has been announced. Consequently, the program continues to operate under regulations issued in 1992.

Determination of the CKM Element V(Ub) (open access)

Determination of the CKM Element V(Ub)

The precise determination of the CKM matrix element |V{sub ub}| is crucial in testing the Standard Model mechanism for CP violation. From a sample of 88 million B{bar B} pairs collected with the BABAR detector, charmless semileptonic B decays are selected using simultaneous requirements on the electron energy, E{sub e}, and the invariant mass squared of the electron-neutrino pair, q{sup 2}. The partial branching fraction, unfolded for detector effects, is determined in a region of the q{sup 2}-E{sub e} plane where the dominating semileptonic decays to charm mesons are highly suppressed. Theoretical calculations based on the Heavy Quark Expanion allows for a determination of |V{sub ub}| = (3.95 {+-} 0.27{sub -0.42}{sup +0.58} {+-} 0.25) x 10{sup -3}, where the errors represent experimental, heavy quark parameters and theoretical uncertainties, respectively.

The Determination of the Helicity of W' Boson Coupling at the LHC (open access)

The Determination of the Helicity of W' Boson Coupling at the LHC

Apart from its mass and width, the most important property of a new charged gauge boson, W{prime}, is the helicity of its couplings to the SM fermions. Such particles are expected to exist in many extensions of the Standard Model. In this paper we explore the capability of the LHC to determine the W{prime} coupling helicity at low integrated luminosities in the {ell} + E{sub T}{sup miss} discovery channel. We find that measurements of the transverse mass distribution, reconstructed from this final state in the W-W{prime} interference region, provides the best determination of this quantity. To make such measurements requires integrated luminosities of {approx} 10(60) fb{sup -1} assuming M{sub W{prime}} = 1.5(2.5) TeV and provided that the W{prime} couplings have Standard Model magnitude. This helicity determination can be further strengthened by the use of various discovery channel leptonic asymmetries, also measured in the same interference regime, but with higher integrated luminosities.

Discovery of Non-random Spatial Distribution of Impacts in the Stardust Cometary Collector (open access)

Discovery of Non-random Spatial Distribution of Impacts in the Stardust Cometary Collector

We report the discovery that impacts in the Stardust cometary collector are not distributed randomly in the collecting media, but appear to be clustered on scales smaller than {approx} 10 cm. We also report the discovery of at least two populations of oblique tracks. We evaluated several hypotheses that could explain the observations. No hypothesis was consistent with all the observations, but the preponderance of evidence points toward at least one impact on the central Whipple shield of the spacecraft as the origin of both clustering and low-angle oblique tracks. High-angle oblique tracks unambiguously originate from a non-cometary impact on the spacecraft bus just forward of the collector.
