Border Security: Improvements Needed to Reduce Time Taken to Adjudicate Visas for Science Students and Scholars

Description: A letter report issued by the General Accounting Office with an abstract that begins "Each year thousands of international science students and scholars apply for visas to enter the United States to participate in education and exchange programs. They offer our country diversity and intellectual knowledge and are an economic resource. At the same time, the United States has important national security interests in screening these individuals when they apply for a visa. At a hearing held by the … more

Individual Fishing Quotas: Economic Effects on Processors and Methods Available to Protect Communities

Description: Testimony issued by the General Accounting Office with an abstract that begins "To address overfishing, the National Marine Fisheries Service started using individual fishing quotas (IFQ) as a fishery conservation and management tool in 1990. Under an IFQ program, a regional fishery management council sets a maximum, or total allowable catch, and allocates the privilege to harvest a certain portion of the catch in the form of quota to individual vessels, fishermen, or other eligible recipients.… more

Human Capital: Preliminary Observations on Proposed DHS Human Capital Regulations

Description: Testimony issued by the General Accounting Office with an abstract that begins "The creation of the Department of Homeland Security (DHS) almost one year ago represents an historic moment for the federal government to fundamentally transform how the nation will protect itself from terrorism. DHS is continuing to transform and integrate a disparate group of agencies with multiple missions, values, and cultures into a strong and effective cabinet department. Together with this unique opportunity,… more

Handling the Handbag Diagram in Compton Scattering on the Proton

Description: Poincare invariance, gauge invariance, conservation of parity and time reversal invariance are respected in an impulse approximation evaluation of the handbag diagram. Proton wave functions, previously constrained by comparison with measured form factors, that incorporate the influence of quark transverse and orbital angular momentum (and the corresponding violation of proton helicity conservation) are used. Computed cross sections are found to be in reasonably good agreement with early measure… more

Recent physics results from CDF and D0

Description: Recent physics results from CDF and D0 on heavy flavor physics, electroweak precision measurements, top physics, QCD and searches for new physics are discussed. The results are based on approximately 140 pb{sup -1} of data collected at {radical}s = 1.96 TeV between 2002 and 2003.

The CDF Run IIb Silicon Detector

Description: Fermilab plans to deliver 5-15 fb{sup -1} of integrated luminosity to the CDF and D0 experiments. The current inner silicon detectors at CDF (SVXIIa and L00) will not tolerate the radiation dose associated with high luminosity running and will need to be replaced. A new readout chip (SVX4) has been designed in radiation-hard 0.25 {micro}m CMOS technology. Single sided sensors are arranged in a compact structure, called a stave, with integrated readout and cooling systems. This paper describes t… more

Oral History Interview with Douglas R. Crawford, February 25, 2004

Description: Interview with Air Force veteran Douglas R. "Roy" Crawford. The interview includes Crawford's personal experiences about early family life, joining the U.S. Army Air Forces, training as a bulldozer operator, removing radioactive debris from Hiroshima, training as a radar operator at Edwards Air Force Base, California, and working as the radar tracker when Major Chuck Yeager broke the sound barrier in the Bell X-1 on October 19, 1947. Additionally, Crawford talks about his assignments to Clark A… more

Isentropic Compression Loading of HMX and the Pressure-induced Phase Transition at 27 GPa

Description: The 27 GPa pressure-induced epsilon-phi phase transition in HMX is explored using the Isentropic Compression Experiment (ICE) technique at the Sandia National Laboratories Z-machine facility. Our data indicate that this phase transition is sluggish and if it does occur to any extent under the time scales (200-500 ns) and strain rates (5 x 10{sup 5}) typical of ICE loading conditions, the amount of conversion is small.

Direct observation of the saturation of stimulated Brillouin scattering by ion-trapping induced frequency shifts

Description: We report the first measurement of the saturation of stimulated Brillouin scattering (SBS) by an ion-trapping induced frequency shift, which was achieved by directly measuring the amplitude and absolute frequency of SBS-driven ion-acoustic waves (IAW). A frequency shift of up to 30% and a simultaneous saturation of driven IAW and SBS reflectivity was observed. The scaling of the frequency shift with the IAW amplitude compares well with theoretical calculations. We have further measured fast 30 … more

XRCC3 ATPase activity is required for normal XRCC3-Rad51C complex dynamics and homologous recombination

Description: Homologous recombinational repair is a major DNA repair pathway that preserves chromosomal integrity by removing double-strand breaks, crosslinks, and other DNA damage. In eukaryotic cells, the Rad51 paralogs (XRCC2, XRCC3, Rad51B, Rad51C, and Rad51D) are involved in this process, although their exact functions are largely undetermined. All five paralogs contain ATPase motifs, and XRCC3 appears to exist in a single complex with Rad51C. To begin to examine the function of this Rad51C-XRCC3 compl… more

Population genetic variation in gene expression is associated withphenotypic variation in Saccharomyces cerevisiae

Description: The relationship between genetic variation in gene expression and phenotypic variation observable in nature is not well understood. Identifying how many phenotypes are associated with differences in gene expression and how many gene-expression differences are associated with a phenotype is important to understanding the molecular basis and evolution of complex traits. Results: We compared levels of gene expression among nine natural isolates of Saccharomyces cerevisiae grown either in the prese… more
