Chemical Activation of Molecules by Metals: Experimental Studies of Electron Distributions and Bonding
This research program is directed at obtaining detailed experimental information on the electronic interactions between metals and organic molecules. These interactions provide low energy pathways for many important chemical and catalytic processes. A major feature of the program is the continued development and application of our special high-resolution valence photoelectron spectroscopy (UPS), and high-precision X-ray core photoelectron spectroscopy (XPS) instrumentation for study of organometallic molecules in the gas phase. The study involves a systematic approach towards understanding the interactions and activation of bound carbonyls, C-H bonds, methylenes, vinylidenes, acetylides, alkenes, alkynes, carbenes, carbynes, alkylidenes, alkylidynes, and others with various monometal, dimetal, and cluster metal species. Supporting ligands include -aryls, alkoxides, oxides, and phosphines. We are expanding our studies of both early and late transition metal species and electron-rich and electron-poor environments in order to more completely understand the electronic factors that serve to stabilize particular organic fragments and intermediates on metals. Additional new directions for this program are being taken in ultra-high vacuum surface UPS, XPS, scanning tunneling microscopy (STM) and atomic force microscopy (AFM) experiments on both physisorbed and chemisorbed organometallic thin films. The combination of these methods provides additional electronic structure information on surface-molecule and molecule-molecule interactions. A …

Chemical Facility Security: Regulation and Issues for Congress
The Department of Homeland Security has proposed security regulations for chemical facilities, implementing the statutory authority granted in Homeland Security Appropriations Act, 2007. The proposed regulations require chemical facilities possessing amounts and yes of substances considered by the DHS Secretary to be hazardous to notify DHS and undergo a consequence-based screening process. This report details the proposed regulations issued by the Department of Homeland Security, key issues, and policy options related to chemical facility security.

Child Support Enforcement: Clear Guidance Would Help Ensure Proper Access To Information and Use of Wage Withholding by Private Firms
A letter report issued by the General Accounting Office with an abstract that begins "To increase child support collections, Congress has considered proposals to improve the ability of private firms to gather information to help locate noncustodial parents and enforce the payment of child support. At the end of fiscal year 2000, the Office of Child Support Enforcement (OCSE) indicated that $89 billion in child support was owed but unpaid--a 96-percent increase since the end of fiscal year 1996. GAO believes that this amount is understated. Thousands of private and public sector entities can collect child support. Both private firms and state agencies reported collections from about 60 percent of their cases. Twenty-two of the 24 private firms GAO reviewed reported that they relied on private information vendors--commercial firms that sell information such as addresses, telephone numbers, and social security numbers--as their primary information source, whereas about one-third of state agencies reported using this source. State agencies relied heavily on state and federal automated databases to locate noncustodial parents and their assets. Additionally, private firms and the state agencies reported calling noncustodial parents to collect child support. However, only the private firms called third parties, such as relatives and neighbors …

Climate response to projected changes in short-lived species under an A1B scenario from 2000-2050 in the GISS climate model
We investigate the climate forcing from and response to projected changes in short-lived species and methane under the A1B scenario from 2000-2050 in the GISS climate model. We present a meta-analysis of new simulations of the full evolution of gas and aerosol species and other existing experiments with variations of the same model. The comparison highlights the importance of several physical processes in determining radiative forcing, especially the effect of climate change on stratosphere-troposphere exchange, heterogeneous sulfate-nitrate-dust chemistry, and changes in methane oxidation and natural emissions. However, the impact of these fairly uncertain physical effects is substantially less than the difference between alternative emission scenarios for all short-lived species. The net global mean annual average direct radiative forcing from the short-lived species is .02 W/m{sup 2} or less in our projections, as substantial positive ozone forcing is largely offset by negative aerosol direct forcing. Since aerosol reductions also lead to a reduced indirect effect, the global mean surface temperature warms by {approx}0.07 C by 2030 and {approx}0.13 C by 2050, adding 19% and 17%, respectively, to the warming induced by long-lived greenhouse gases. Regional direct forcings are large, up to 3.8 W/m{sup 2}. The ensemble-mean climate response shows little regional …

Colliding with a crunching bubble
In the context of eternal inflation we discuss the fate of Lambda = 0 bubbles when they collide with Lambda< 0 crunching bubbles. When the Lambda = 0 bubble is supersymmetric, it is not completely destroyed by collisions. If the domain wall separating the bubbles has higher tension than the BPS bound, it is expelled from the Lambda = 0 bubble and does not alter its long time behavior. If the domain wall saturates the BPS bound, then it stays inside the Lambda = 0 bubble and removes a finite fraction of future infinity. In this case, the crunch singularity is hidden behind the horizon of a stable hyperbolic black hole.

Collins Fragmentation and the Single Transverse Spin Asymmetry
We study the Collins mechanism for the single transverse spin asymmetry in the collinear factorization approach. The correspondent twist-three fragmentation function is identified. We show that the Collins function calculated in this approach is universal.We further examine its contribution to the single transverse spin asymmetry of semi-inclusive hadron production in deep inelastic scattering and demonstrate that the transverse momentum dependent and twist-three collinear approaches are consistent in the intermediate transverse momentum region where both apply.

Cosmological Constraints From SDSS MaxBCG Cluster Abundances
We perform a maximum likelihood analysis of the cluster abundance measured in the SDSS using the maxBCG cluster finding algorithm. Our analysis is aimed at constraining the power spectrum normalization {sigma}{sub 8}, and assumes flat cosmologies with a scale invariant spectrum, massless neutrinos, and CMB and supernova priors {Omega}{sub m}h{sup 2} = 0.128 {+-} 0.01 and h = 0.72 {+-} 0.05 respectively. Following the method described in the companion paper Rozo et al. (2007), we derive {sigma}{sub 8} = 0.92 {+-} 0.10 (1{sigma}) after marginalizing over all major systematic uncertainties. We place strong lower limits on the normalization, {sigma}{sub 8} > 0.76 (95% CL) (> 0.68 at 99% CL). We also find that our analysis favors relatively low values for the slope of the Halo Occupation Distribution (HOD), {alpha} = 0.83 {+-} 0.06. The uncertainties of these determinations will substantially improve upon completion of an ongoing campaign to estimate dynamical, weak lensing, and X-ray cluster masses in the SDSS maxBCG cluster sample.

Creating interoperable meshing and discretization software : the terascale simulation tools and technology center.
The authors present an overview of the technical objectives of the Terascale Simulation Tools and Technologies center. The primary goal of this multi-institution collaboration is to develop technologies that enable application scientists to easily use multiple mesh and discretization strategies within a single simulation on terascale computers. The discussion focuses on the efforts to create interoperable mesh generation tools, high-order discretization techniques, and adaptive meshing strategies.
