Oral History Interview with Claiborn Wamsley, August 29, 2005 (open access)

Oral History Interview with Claiborn Wamsley, August 29, 2005

The National Museum of the Pacific War presents an oral interview with Claiborn Wamsley. Wamsley joined the Navy in November, 1943 and attended signal school after boot training. He was then assigned to USS LST-1040, picked it up in Pittsburgh and rode down the Ohio and Mississippi rivers to New Orleans. From there, they traveled to Pearl Harbor. From there, the 1040 went to Okinawa to unload supplies. He also recalls being caught in typhoons. After the war, Wamsley spent time in Japan and China delivering materials and people to various ports. He returned to the US and was discharged in June, 1946.

A Precise Sum Rule among Four B -> K pi CP Asymmetries (open access)

A Precise Sum Rule among Four B -> K pi CP Asymmetries

A sum rule relation is proposed for direct CP asymmetries in B {yields} K{pi} decays. Leading terms are identical in the isospin symmetry limit, while subleading terms are equal in the flavor SU(3) and heavy quark limits. The sum rule predicts A{sub CP}(B{sup 0} {yields} K{sup 0}{pi}{sup 0}) = -0.17 {+-} 0.06 using current asymmetry measurements for the other three B {yields} K{pi} decays. A violation of the sum rule would be evidence for New Physics in b {yields} s{bar q}q transitions.

Prediction of coherent optical radiation from shock waves in polarizable crystals (open access)

Prediction of coherent optical radiation from shock waves in polarizable crystals

We predict that coherent electromagnetic radiation in the 1-100 THz frequency range can be generated in crystalline materials when subject to a shock wave or soliton-like propagating excitation. To our knowledge, this phenomenon represents a fundamentally new form of coherent optical radiation source that is distinct from lasers and free-electron lasers. General analytical theory and molecular dynamics simulations demonstrate coherence lengths on the order of mm (around 20 THz) and potentially greater. The emission frequencies are determined by the shock speed and the lattice constants of the crystal and can potentially be used to determine atomic-scale properties of the shocked material.

Production of Arrayed and Rearrayed cDNA Libraries for Public Use (open access)

Production of Arrayed and Rearrayed cDNA Libraries for Public Use

Researchers studying genes and their protein products need an easily available source for that gene. The I.M.A.G.E. Consortium at Lawrence Livermore National Laboratory is an important source of such genes in the form of arrayed cDNA libraries. The arrayed clones and associated data are available to the public, free of restriction. Libraries are transformed and titered into 384-well master plates, from which 2-8 copies are made. One copy plate is stored by LLNL while others are sent to sequencing groups, plate distributors, and to the group which contributed the library. Clones found to be unique and/or full-length are rearrayed and also made publicly available. Bioinformatics tools supporting the use of I.M.A.G.E. clones are accessible via the World Wide Web.

Quantum-based Atomistic Simulation of Transition Metals (open access)

Quantum-based Atomistic Simulation of Transition Metals

First-principles generalized pseudopotential theory (GPT) provides a fundamental basis for transferable multi-ion interatomic potentials in d-electron transition metals within density-functional quantum mechanics. In mid-period bcc metals, where multi-ion angular forces are important to structural properties, simplified model GPT or MGPT potentials have been developed based on canonical d bands to allow analytic forms and large-scale atomistic simulations. Robust, advanced-generation MGPT potentials have now been obtained for Ta and Mo and successfully applied to a wide range of structural, thermodynamic, defect and mechanical properties at both ambient and extreme conditions of pressure and temperature. Recent algorithm improvements have also led to a more general matrix representation of MGPT beyond canonical bands allowing increased accuracy and extension to f-electron actinide metals, an order of magnitude increase in computational speed, and the current development of temperature-dependent potentials.

Recent BaBar Results on Hadron Spectroscopy (open access)

Recent BaBar Results on Hadron Spectroscopy

Recent results from on hadronic spectroscopy are presented, based on data collected by the BaBar experiment between 1999 and 2004. The properties of the recently discovered D*{sub sJ}(2317){sup +} and D{sub sJ}(2460){sup +} states are studied: resonance parameters and ratios of decay rates are measured from continuum e{sup +}e{sup -} production, and production rates are measured from B decays. A search for the D*{sub sJ}(2632){sup +} state whose observation has been recently reported by the SELEX Collaboration, and a search for a charged partner of the charmonium-like X(3872) state, are performed, yielding negative results. Finally, extensive searches for several pentaquark candidates, both fully inclusive and in B decays, result in no positive evidence.

Registered Apprenticeship Programs: Labor Can Better Use Data to Target Oversight (open access)

Registered Apprenticeship Programs: Labor Can Better Use Data to Target Oversight

A letter report issued by the Government Accountability Office with an abstract that begins "Between 2002 and 2012 nearly 850,000 jobs will open in the construction industry; experts predict that there will not be enough skilled workers to fill them. This has heightened concerns about program outcomes and program quality in the nation's apprenticeship system and the U.S. Department of Labor's oversight of it. GAO assessed (1) the extent to which Labor monitors registered apprenticeship programs in the states where it has direct oversight, (2) its oversight activities in states that do their own monitoring, and (3) the outcomes for construction apprentices in programs sponsored by employers and unions in relation to programs sponsored by employers alone."

THE RELATIVISTIC HEAVY ION COLLIDER (RHIC) REFRIGERATOR SYSTEM AT BROOKHAVEN NATIONAL LABORATORY: PHASE III OF THE SYSTEM PERFORMANCE AND OPERATIONS UPGRADES FOR 2003 (open access)

THE RELATIVISTIC HEAVY ION COLLIDER (RHIC) REFRIGERATOR SYSTEM AT BROOKHAVEN NATIONAL LABORATORY: PHASE III OF THE SYSTEM PERFORMANCE AND OPERATIONS UPGRADES FOR 2003

An ongoing program at Brookhaven National Laboratory (BNL) consists of improving the efficiency of the Relativistic Heavy Ion Collider (RHIC) cryogenic system and reducing its power consumption. Phase I and I1 of the program addressed plant operational improvements and modifications that resulted in substantial operational cost reduction and improved system reliability and stability, and a compressor input power reduction of 2 MW has been demonstrated. Phase 111, now under way, consists of plans for further increasing the efficiency of the plant by adding a load ''wet'' turbo-expander and its associated heat exchangers at the low temperature end of the plant. This additional stage of cooling at the coldest level will further reduce the required compressor flow and therefore compressor power input. This paper presents the results of the plant characterization, as it is operating presently, as well as the results of the plant simulations of the various planned upgrades for, the plant. The immediate upgrade includes the changes associated with the load expander. The subsequent upgrade will involve the resizing of expander 5 and 6 to increase their efficiencies. The paper summarizes the expected improvement in the plant efficiency and the overall reduction in the compressor power.

Scaling of Pressure with Intensity in Laser-Driven Shocks and Effects of Hot X-ray Preheat (open access)

Scaling of Pressure with Intensity in Laser-Driven Shocks and Effects of Hot X-ray Preheat

To drive shocks into solids with a laser we either illuminate the material directly, or to get higher pressures, illuminate a plastic ablator that overlays the material of interest. In both cases the illumination intensity is low, <<10{sup 13} W/cm{sup 2}, compared to that for traditional laser fusion targets. In this regime, the laser beam creates and interacts with a collisional, rather than a collisionless, plasma. We present scaling relationships for shock pressure with intensity derived from simulations for this low-intensity collisional plasma regime. In addition, sometimes the plastic-ablator targets have a thin flashcoating of Al on the plastic surface as a shine-through barrier; this Al layer can be a source of hot x-ray preheat. We discuss how the preheat affects the shock pressure, with application to simulating VISAR measurements from experiments conducted on various lasers on shock compression of Fe.

Water Imbibition into Rock as Affected by Sample Shape, Pore, Conductivity, and Antecedent Water Content (open access)

Water Imbibition into Rock as Affected by Sample Shape, Pore, Conductivity, and Antecedent Water Content

Infiltration is often presumed to follow Philip's equation, I = st{sup 1/2}, where I is cumulative infiltration, s is sorptivity, and t is time. This form of the equation is appropriate for short times, and/or for negligible gravitational effects. For a uniform soil, this equation describes a plot of log(mass imbibed) versus log(time), with a slope (imbibition exponent) of 1/2. The equation has also been applied to low-porosity rocks, where the extremely small pores render gravitational forces negligible. Experiments recently performed on a wide variety of rocks produced imbibition exponents from 0.2 to 0.5. Many rock types showed initial imbibition proceeding as I {approx} t{sup 1/4}, then later switched to ''normal'' (t{sup 1/2}) behavior. The distance to the wetting front that corresponds to this cross-over behavior was found to be related to the sample shape: tall thin samples are more likely to exhibit the exponent 1/4, and to cross over to 1/2-type behavior later, while short, squat samples are less likely to display the 1/4-type behavior at all. Additionally, the exponents are sensitive to antecedent water content, with initially wetter samples having smaller values. In this study, we present the experimental data, and provide a consistent and physically-based explanation using …

Water Under the Extreme Conditions of Planetary Interiors: Symmetric Hydrogen Bonding in the Superionic Phase (open access)

Water Under the Extreme Conditions of Planetary Interiors: Symmetric Hydrogen Bonding in the Superionic Phase

The predicted superionic phase of water is investigated via ab initio molecular dynamics at densities of 2.0-3.0 g/cc (34 -115 GPa) along the 2000K isotherm.We find that extremely rapid (superionic) diffusion of protons occurs in a fluid phase at pressures between 34 and 58 GPa. A transition to a stable body-centered cubic (bcc) O lattice with superionic proton conductivity is observed between 70 and 75 GPa, a much higher pressure than suggested in prior work. We find that all molecular species at pressures greater than 75 GPa are too short lived to be classified as bound states. Above 95 GPa, a transient network phase is found characterized by symmetric O-H hydrogen bonding with nearly 50% covalent character.

X-Ray CT of Highly-Attenuating Objects: 9- or 15- MV Spectra? (open access)

X-Ray CT of Highly-Attenuating Objects: 9- or 15- MV Spectra?

We imaged-highly attenuating test objects in three dimensions with 9-MV (at LLNL) and 15-MV (at Hill Air Force Base) x-ray spectra. While we used the same detector and motion control, there were differences that we could not control in the two radiography bays and in the sources. The results show better spatial resolution for the 9-MV spectrum and better contrast for the 15-MV spectrum. The 15-MV data contains a noise pattern that obfuscates the data. It is our judgment that if sufficient attention were given to design of the bay, beam dump, collimation, filtration and linac spot size; a 15-MV imaging system using a flat panel could be developed with spatial resolution of 5 lp/mm and contrastive performance better than we have demonstrated using a 9-MV spectrum.
