Analysis of polarimeter data for the 2001-2002 RHIC run.

Description: The results of several studies of the 200-MeV (LINAC), AGS (E880), and RHIC polarimeter data from the polarized proton run in 2001/2002 are presented. Much of this work occurred during or immediately after the run. Some of these analyses have implications for the understanding of the performance of the polarized ion source, AGS, and RHIC with polarized protons. Some of the conclusions include: (A) A recalibration of the 200-MeV polarimeter gives results consistent with the older calibration, bu… more

Analytical and Numerical Ray Tracing of X-Ray Lasers

Description: Soft x-ray lasers in 10-30nm range are now routinely produced in hot plasmas generated either by a laser from a solid target or by an electrical discharge in a capillary. Such an x-ray laser is a convenient tool for future applications, such as probing dense plasmas of interest for fusion experiments. Their short wavelength enables plasma diagnosis beyond the capabilities of optical lasers, because the high critical plasma density ({approx}{lambda}{sup 2}) limits the optical beam propagation. I… more

Automatic Discovery and Inferencing of Complex Bioinformatics Web Interfaces

Description: The World Wide Web provides a vast resource to genomics researchers in the form of web-based access to distributed data sources--e.g. BLAST sequence homology search interfaces. However, the process for seeking the desired scientific information is still very tedious and frustrating. While there are several known servers on genomic data (e.g., GeneBank, EMBL, NCBI), that are shared and accessed frequently, new data sources are created each day in laboratories all over the world. The sharing of t… more

Cesium Ion Exchange Using Tank 241-AN-104 Supernate

Description: The River Protection Project is to design and build a high level nuclear waste treatment facility. The waste treatment plant is to process millions of gallons of radioactive waste stored in tanks at the Hanford Site. The high level nuclear waste treatment process includes various unit operations, such as ultrafiltration, precipitation, evaporation, ion exchange, and vitrification. Ion exchange is identified as the optimal treatment method for removal of cesium-137 and Tc-99 from the waste. Exte… more

Determination of the Effect of Uranium Levels on Sludge Batch 2 Processing

Description: The Defense Waste Processing Facility began processing Sludge Batch 2 in December of 2001. Since the introduction of the first complete process batch from Sludge Batch 2, processing issues have been observed in the Sludge Receipt and Adjustment Tank , Slurry Mix Evaporator, Melter Feed Tank and the melter. Testing was done to determine what effect different levels of uranium would have on the processing of Sludge Batch 2 in the Defense Waste Processing Facility Chemical Processing Cell. Two lev… more

Downstream Impacts of Tank 48H In-tank and Out-of-tank Processing Alternatives

Description: This document discusses a number of possible impacts that an in-tank or out-of-tank process may have on downstream processing facilities. The analysis is part of a task to develop processes to destroy tetraphenylborate using Fenton Chemistry (metal catalyst plus hydrogen peroxide). Two processes being evaluated are funded by a grant from DOE's National Energy Technology Center. The first is an in-tank process, where the tetraphenylborate is destroyed by decreasing the pH, increasing the tempera… more

The Effect of Habitat Inhomogeneities and Fragmentation on Population Density and Time to Extinction

Description: We present a study, based on simulations with SERDYCA, a spatially-explicit individual based model of rodent dynamics, on the connection between population persistence and the presence of inhomogeneities in the habitat. We are specifically interested on the effect that inhomogeneities that do not fragment the environment, have on population persistence. Our results suggest that a certain percentage of inhomogeneities can increase the average time to extinction of the population. Inhomogeneities… more

Fundamental and Magnetic-Hardening Studies of Rare-Earth and Nanocomposite Magnets

Description: In this project we study new nanocrystalline and nanocomposite structures that have high potential for permanent-magnet development. These materials, which can be synthesized to have either very high or intermediate coercivities, have many applications in electric power, transportation, and information-storage industries. There is great interest in further development of understanding and application of these materials.

The Islamic Traditions of Wahhabism and Salafiyya

Description: The terrorist attacks of September 11, 2001, and subsequent investigations of these attacks have called attention to Islamic puritanical movements known as Wahhabism and Salafiyya. This report provides a background on Wahhabi Islam and its association to militant fundamentalist groups; it will also summarize recent charges against Wahhabism and responses.

Isochoric Heating of Solid-Density Matter with an Ultrafast Proton Beam

Description: A new technique is described for the isochoric heating (i.e., heating at constant volume) of matter to high energy-density plasma states (>10{sup 5} J/g) on a picosecond timescale (10{sup -12} sec). An intense, collimated, ultrashort-pulse beam of protons--generated by a high-intensity laser pulse--is used to isochorically heat a solid density material to a temperature of several eV. The duration of heating is shorter than the timescale for significant hydrodynamic expansion to occur, hence … more

Multinomial Combinatorial Group Representations of the Octahedral and Cubic Symmetries

Description: We consider the full multinomial combinatorics of all irreducible representations of the octahedral (cubic) symmetry as a function of partitions for vertex, face and edge colorings. Full combinatorial tables for all irreducible representations and all multinomial partitions are constructed. These enumerations constitute multinomial expansions of character-based cycle index polynomials, and grow in combinatorial complexity as a function of edge or vertex coloring partitions.

Relativistic Double Group Spinor Representations of Non-rigid Molecules

Description: The character theory of relativistic double group spinor representations is developed in order to represent the total rovibronic states of non-rigid molecules. It is shown that the double groups can be represented in terms of wreath products and powerful matrix cycle type generators that are used to construct their character tables. It is shown that these tables are of use when spin-orbit coupling is included in the hamiltonian even for molecules containing lighter atoms. Applications to non-ri… more

Spectroscopic Properties and Potential Energy Curves of Low-lying electronic States of RuC

Description: The RuC molecule has been a challenging species due to the open-shell nature of Ru resulting in a large number of low-lying electronic states. We have carried out state-of-the-art calculations using the complete active space multi-configuration self-consistent field (CASSCF) followed by multireference configuration interaction (MRCI) methods that included up 18 million configurations, in conjunction with relativistic effects. We have computed 29 low-lying electronic states of RuC with different… more

Chemoselective Attachment of Biologically Active Proteins to Surfaces by Native Chemical Ligation

Description: The present work describes our ongoing efforts towards the creation of micro and nanoscaled ordered arrays of protein covalently attached to site-specific chemical linkers patterned by different microlithographic techniques. We present a new and efficient solid-phase approach for the synthesis of chemically modified long alkyl-thiols. These compounds can be used to introduce chemoselective reacting groups onto silicon-based surfaces. We show that these modified thiols can be used for creating n… more
