Direct Observations of Sigma Phase Formation in Duplex Stainless Steels using In Situ Synchrotron X-Ray Diffraction

Description: The formation and growth of sigma phase in 2205 duplex stainless steel was observed and measured in real time using synchrotron radiation during 10 hr isothermal heat treatments at temperatures between 700 C and 850 C. Sigma formed in near-equilibrium quantities during the isothermal holds, starting from a microstructure which contained a balanced mixture of metastable ferrite and austenite. In situ synchrotron diffraction continuously monitored the transformation, and these results were compar… more

HOTTER, SMALLER, DENSER, FASTER...AND NEARLY-PERFECT: WHAT IS THE MATTER AT RHIC?

Description: The experimental and theoretical status of the ''near perfect fluid'' at RHIC is discussed. While the hydrodynamic paradigm for understanding collisions at RHIC is well established, there remain many important open questions to address in order to understand its relevance and scope. It is also a crucial issue to understand how the early equilibration is achieved, requiring insight into the active degrees of freedom at early times.

Snapping Supernovae at z>1.7

Description: We examine the utility of very high redshift Type Ia supernovae for cosmology and systematic uncertainty control. Next generation space surveys such as the Supernova/Acceleration Probe (SNAP) will obtain thousands of supernovae at z>1.7, beyond the design redshift for which the supernovae will be exquisitely characterized. We find that any z gtrsim 2 standard candles' use for cosmological parameter estimation is quite modest and subject to pitfalls; we examine gravitational lensing, redshift… more

FLUCTUATION AND LOW TRANSVERSE MOMENTUM CORRELATION RESULTS FROM PHENIX.

Description: The PHENIX Experiment at the Relativistic Heavy Ion Collider has conducted a survey of fluctuations in charged hadron multiplicity in Au+Au and Cu+Cu collisions at {radical}s{sub NN} = 22, 62, and 200 GeV. A universal power law scaling for multiplicity fluctuations expressed as {sigma}{sup 2}/{mu}{sup 2} is observed as a function of N{sub part} for all species studied that is independent of the transverse momentum range of the measurement. PHENIX has also measured transverse momentum correlatio… more

ENTROPY PRODUCTION AT HIGH ENERGY AND mu B.

Description: The systematics of bulk entropy production in experimental data on Ai-A, p + y and e{sup +}e{sup -} interactions at high energies and large {mu}{sub B} is discussed. It is proposed that scenarios with very early thermalization, such as Landau's hydrodynamical model, capture several essential features of the experimental results. It is also pointed out that the dynamics of systems which reach the hydrodynamic regime give similar multiplicities and angular distributions as those calculated in wea… more

Overview of Theory and Simulations in the Heavy Ion Fusion Science Virtual National Laboratory

Description: The Heavy Ion Fusion Science Virtual National Laboratory (HIFS-VNL) is a collaboration of Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory, and Princeton Plasma Physics Laboratory. These laboratories, in cooperation with researchers at other institutions, are carrying out a coordinated effort to apply intense ion beams as drivers for studies of the physics of matter at extreme conditions, and ultimately for inertial fusion energy. Progress on this endeavor depends u… more

Development and anlysis of fast, approximate 3D Algorithms for interpretation of multi-component induction logging data

Description: This report addresses the effects of electrical anisotropy on the 3D inversion of single-well induction logging data when anisotropy is not considered. Of concern are possible artifacts that may lead to an incorrect interpretation of the formation about the borehole. Comparison is made of 3D isotropic inversion on a suite of model data, with and without anisotropy, consisting of an infinite layer and layer terminated at the borehole. In both cases, the layer dip (or well deviation) is varied. I… more

War on Drugs: The National Youth Anti-Drug Media Campaign

Description: This report discusses the authorization of the National Youth Anti-Drug Media Campaign, a multi-media federal program to persuade America's youth not to use drugs, which expired at the end of FY2002. H.R. 2829 (passed by the House on March 13, 2006) and S. 2560 (reported by the Senate Judiciary Committee on May 25, 2006) would reauthorize the media campaign, along with the other programs run by the Office of National Drug Control Policy (ONDCP) during FY2007.

Disaster Debris Removal After Hurricane Katrina: Status and Associated Issues

Description: This report discusses issues associated with debris removal operations after a disaster on the scale of Katrina. In particular, it discusses why debris removal was an ongoing concern months after the hurricane, as well as factors that make debris removal such a costly, complex operation.

Design of a Virtual Quadrant Receiver for 4-ary Pulse Position Modulation/Optical CDMA (4-ary PPM/O-CDMA)

Description: We describe a receiver that performs optical code division multiple access (O-CDMA) decoding followed by pulse position modulation (PPM) symbol detection that behaves like a radar quadrant receiver. Simulations determine the impact of multi-access interference on symbol detection for up to 32 users.

First principles study of the Young's modulus of Si <001> nanowires

Description: We report the results of first-principles calculations of the Young's modulus and other mechanical properties of hydrogen-passivated Si &lt;001&gt; nanowires. The nanowires are taken to have predominantly {l_brace}100{r_brace} surfaces, with small {l_brace}110{r_brace} facets according to the Wulff shape. The Young's modulus, the equilibrium length and the constrained residual stress of a series of prismatic beams of differing sizes is found to have a size dependence that scales like the surfac… more

Exploration of methods to identify polymorphisms associated with variation in DNA repair capacity phenotypes

Description: Elucidating the relationship between polymorphic sequences and risk of common disease is a challenge. For example, although it is clear that variation in DNA repair genes is associated with familial cancer, aging and neurological disease, progress toward identifying polymorphisms associated with elevated risk of sporadic disease has been slow. This is partly due to the complexity of the genetic variation, the existence of large numbers of mostly low frequency variants and the contribution of ma… more

Emergency Funding for Agriculture: A Brief History of Supplemental Appropriations, FY1989-FY2006

Description: From FY1989 through FY2006, 33 appropriations, authorization, or farm disaster acts added approximately $55.4 billion in supplemental funding for U.S. Department of Agriculture (USDA) programs. The two most recent supplemental appropriations were provided in response to Hurricanes Katrina and Rita in the Gulf of Mexico and in preparation for a possible U.S. outbreak of avian influenza. Some FY1989, the vast majority of the total supplemental funding has been paid directly to farmers, primarily … more
