Oxidative Reactions with Nonaqueous Enzymes
The objective of this work is to demonstrate a proof-of-concept of enzymatic oxidative processing in nonaqueous media using alkene epoxidation and phenolic polymerization as relevant targets. This project will provide both the fundamental and applied investigations necessary to initiate the implementation of oxidative biocatalysts as commercially relevant alternatives to chemical processing in general, and to phenolic polymerizations and alkene epoxidation specifically. Thus, this work will address the Bioprocessing Solicitation Area to: (1) makes major improvements to phenolic polymerization and alkene epoxidation technologies; (2) is expected to be cost competitive with competing conventional processes; and (3) produces higher yields with less waste.

2000 Census: Analysis of Fiscal Year 2000 Budget and Internal Control Weaknesses at the U.S. Census Bureau
A letter report issued by the General Accounting Office with an abstract that begins "In September 2000, the U.S. Census Bureau told Congress that it had at least $305 million in budget savings out of its $4.5 billion fiscal year 2000 no-year appropriations for the 2000 decennial census. Of the $4.5 billion appropriated to the U.S. Census Bureau in fiscal year 2000, lower-than-expected expenditures and obligations resulted in available balances of at least $415 million. A lower-than-expected support staff workload reduced salary and benefit costs by about $348 million. Enumerator workload is largely determined by the initial mail response rate for returned census questionnaires. The initial mail response of 64 percent meant that Census enumerators did not have to visit more than three million American households. However, the available balances from the higher mail response rate and the lower support staff workload were partially offset by about $100 million of higher salary and benefit costs for enumerators, including a higher workload for unanticipated recounts. According to Bureau data, enumerator productivity did not significantly affect budget variances for the 2000 decennial census. The Bureau reported the national average time to visit a household and complete a census questionnaire was about the …

Benchmarking and tuning the MILC code on clusters and supercomputers
Recently, we have benchmarked and tuned the MILC code on a number of architectures including Intel Itanium and Pentium IV (PIV), dual-CPU Athlon, and the latest Compaq Alpha nodes. Results will be presented for many of these, and we shall discuss some simple code changes that can result in a very dramatic speedup of the KS conjugate gradient on processors with more advanced memory systems such as PIV, IBM SP and Alpha.

Cost of dynamical quark simulations with improved staggered quarks
The cost of dynamical quark simulations with improved staggered quarks is estimated based on current and planned running by the MILC collaboration. I find that a few 10s of Tera op years should be sufficient to calculate down to a lattice spacing of 0.045 fm.

Gas Releases During Saltcake Dissolution for Retrieval of Single-Shell Tank Waste, Rev. 1
It is possible to retrieve a large fraction of soluble waste from the Hanford single-shell waste tanks (SSTs) by dissolving it with water. This retrieval method will be demonstrated in Tanks U-107 and S-112 in the next few years. If saltcake dissolution proves practical and effective, many of the saltcake SSTs may be retrieved by this method. Many of the SSTs retain flammable gas that will be released into the tank headspace as the waste dissolves. This report describes the physical processes that control dissolution and gas release. Calculation results are shown and describe how the headspace hydrogen concentration evolves during dissolution. The observed spontaneous and induced gas releases from SSTs are summarized, and the dissolution of the crust layer in SY-101 is discussed as a recent example of full-scale dissolution of saltcake containing a large volume of retained gas. The report concludes that the dissolution rate is self-limiting and that gas release rates are relatively low.

In celebration of the fixed target program with the Tevatron
The Tevatron is the world's first large superconducting accelerator. With its construction, we gained the dual opportunities to advance the state of the art in accelerator technology with the machine itself and in particle physics with the experiments that became possible in a higher energy regime. There have been 43 experiments in the Tevatron fixed target program. Many of these are better described as experimental programs, each with a broad range of physics goals and results, and more than 100 collaborating physicists and engineers. The results of this program are three-fold: (1) new technologies in accelerators, beams and detectors which advanced the state of the art; (2) new experimental results published in the refereed physics journals; and (3) newly trained scientists who are both the next generation of particle physicists and an important part of the scientific, technical and educational backbone of the country as a whole. In this book they compile these results. There are sections from each experiment including what their physics goals and results were, what papers were published, and which students have received degrees. Summaries of these results from the program as a whole are quite interesting, but the physics results from this program are too …

Moisture Distribution and Flow During Drying of Wood and Fiber
New understanding, theories, and techniques for moisture flow and distribution were developed in this research on wood and wood fiber. Improved understanding of the mechanisms of flake drying has been provided. Observations of flake drying and drying rate curves revealed that rate of moisture loss consisted of two falling rate periods and no constant rate drying period was observed. Convective heat transfer controls the first period, and bound water diffusion controls the second period. Influence of lower drying temperatures on bending properties of wood flakes was investigated. Drying temperature was found to have a significant influence on bending stiffness and strength. A worksheet for calculation of the energy required to dry a single strandboard flake was developed but has not been tested in an industrial setting yet. A more complete understanding of anisotropic transverse shrinkage of wood is proposed based on test results and statistical analysis. A simplified mod el of a wood cell's cross-section was drawn for calculating differential transverse shrinkage. The model utilizes cell wall thickness and microfibrillar packing density and orientation. In spite of some phenomena of cell wall structure not yet understood completely, the results might explain anisotropic transverse shrinkage to a major extent. Boundary layer …

On the large Nc expansion in quantum chromodynamics
The author discusses methods based on the large Nc expansion to study nonperturbative aspects of quantum chromodynamics, the theory of the strong force. The author applies these methods to the analysis of weak decay processes and the nonperturbative computation of the weak matrix elements needed for a complete evaluation of these decays in the Standard Model of elementary particle physics.

Regulatory Reform: Compliance Guide Requirement Has Had Little Effect on Agency Practices
A letter report issued by the General Accounting Office with an abstract that begins "Section 212 of the Small Business Regulatory Enforcement Fairness Act requires agencies to publish compliance guides for each rule or group of related rules for which the agency is required to prepare a final regulatory flexibility analysis. GAO found that Section 212 has had little impact, and its implementation has varied across and sometimes within the agencies. None of the agencies in GAO's review provided GAO with guidance documents that met all of the statutory requirements for all of their 1999 and 2000 final rules. The agencies indicated that they tried to put their compliance guides in plain language--just as they have for all their regulatory materials. The guidance documents that the agencies gave GAO were often published on the agencies' web sites. Direct mail, electronic list servers, agency/regional offices, and workshops were also used for distribution."

Superconducting superferric dipole magnet with cold iron core for the VLHC
The magnet system of the Very Large Hadron Collider (VLHC) Stage I is based on a superconducting 2 Tesla magnetic field combined function magnets. These magnets will have a room temperature iron core with two 20 mm air gaps. Magnetic field in both horizontally separated air gaps is excited by a single turn 100 kA superconducting transmission line. The alternative design with cold iron core, horizontally or vertically separated air gaps is under investigation. The cold iron option with horizontally separated air gaps reduces the amount of iron, which is one of the main cost driver for 233 km length magnet system of the future accelerator. The vertical beam separation decreases volume superconductor, heat load from synchrotron radiation and eliminates fringing field from a return bus. But the horizontal beam separation has lowest volume of iron core and as a result lower heat load for cryosystem during cooling down. All these options are discussed and comparison is made. Superconducting correction system, combined with the magnet, allowing to increase the maximum field is also under discussion. Preliminary cost analysis are made for all options.

Supersymmetry searches at the Collider Detector at Fermilab
This article presents the current experimental results of searches for Supersymmetry (SUSY) at the Collider Detector at Fermilab (CDF), using over 110 pb{sup -1} of proton-antiproton collision data with {radical}s = 1800 GeV collected during the period 1992-1995. Since no signal was found, limits on the production of supersymmetric particles are derived. The prospects for supersymmetry searches at Run II of the Tevatron, that began in March 2001, are also discussed here.

China-U.S. Trade Issues
U.S.-China economic ties have expanded substantially over the past several years. China is now the third largest U.S. trading partner, its second largest source of imports, and its fourth largest export market. However, U.S.-China commercial ties have been strained by a number of issues, including a surging U.S. trade deficit with China, China's refusal to float its currency, and failure to fully comply with its World Trade Organization (WTO) commitments, especially its failure to provide protection for U.S. intellectual property rights (IPR). This report explores these issues in detail, especially concerning the lack of protection for U.S. IPR.

China's Economic Conditions
Currently, China’s short-term economic outlook is unclear. Economic slowdowns in Asia and the United States in the beginning of 2001 have hurt China’s export industries, and the September 11, 2001 terrorist attacks against the United States will likely further dampen foreign demand for Chinese products and could reduce the level of planned foreign investment in China. The Chinese government has used public spending in recent years to boost the economy, and it is likely that it will continue to maintain such policies until the global economy begins to recover.

Individuals with Disabilities Education Act: Full Funding of State Formula
This report discusses Individuals with Disabilities Education Act (IDEA), which assists participating states to serve school-age children with disabilities. The state funding formula, which provides a foundation amount based on states’ FY1999 grants and allocates remaining amounts based on states’ shares of school-age children and of school-age poor children, authorizes a maximum allotment per disabled child served of 40% of the national average per pupil expenditure (APPE). Annual appropriations have never been sufficient to provide each state its maximum allotment; in FY2002, states will receive approximately 16.5% of the national APPE per disabled child served. Some advocates for the program have called upon the Congress to fully fund the formula. An estimated $18.2 billion would be required to provide states the maximum allotment allowed per disabled child served in FY2002, about 2.4 times more than the appropriation of $7.5 billion for FY2002.

Optimum Vehicle Component Integration with InVeST (Integrated Vehicle Simulation Testbed)
We have developed an Integrated Vehicle Simulation Testbed (InVeST). InVeST is based on the concept of Co-simulation, and it allows the development of virtual vehicles that can be analyzed and optimized as an overall integrated system. The virtual vehicle is defined by selecting different vehicle components from a component library. Vehicle component models can be written in multiple programming languages running on different computer platforms. At the same time, InVeST provides full protection for proprietary models. Co-simulation is a cost-effective alternative to competing methodologies, such as developing a translator or selecting a single programming language for all vehicle components. InVeST has been recently demonstrated using a transmission model and a transmission controller model. The transmission model was written in SABER and ran on a Sun/Solaris workstation, while the transmission controller was written in MATRIXx and ran on a PC running Windows NT. The demonstration was successfully performed. Future plans include the applicability of Co-simulation and InVeST to analysis and optimization of multiple complex systems, including those of Intelligent Transportation Systems.
