The CDF miniplug calorimeters
Two MiniPlug calorimeters, designed to measure the energy and lateral position of particles in the (forward) pseudorapidity region of 3.6 < |{nu}| < 5.2 of the CDF detector, have been recently installed as part of the Run II CDF upgrade at the Tevatron {bar p}p collider. They consist of lead/liquid scintillator read out by wavelength shifting fibers arranged in a pixel-type towerless geometry suitable for ''calorimetric tracking''. The design concept, the prototype performance and the final design of the MiniPlugs are here described. A recent cosmic ray test resulted in a light yield of approximately 100 pe/MIP, which exceeds our design requirements.

Characterization of Radionuclides in Waste Sludges from High Level Waste Tanks 40, 42, and 51
This document will develop a radionuclide distribution for the sludge fraction of sludge-contaminated waste stored in High Level Waste Tanks 40, 42 and 51 in accordance with the methodology outlined in WAC 2.02 (Rev. 4). A single, comprehensive characterization for supernate has been developed previously (Reference 5). This distribution is based on the assumption that sludge-contaminated waste from tanks 40, 42 and 51 may be co-mingled, and the actual contamination present on waste in a series of containers from these tanks will be representative of the mean radionuclide distribution. This document also describes the methodology for application of radionuclide distributions representative of the sludge and supernate fractions of sludge-contaminated waste to individual waste packages.

Chemometric Classification of Unknown Vapors by Conversion of Sensor Array Pattern Vectors to Vapor Descriptors: Extension from Mass-Transducing Sensors To Volume-Transducing Sensors
A new chemometric method was recently described for classifying unknowns by transforming the vector containing the responses from a multivariate detector to a vector containing descriptors of the detected analyte (Grate et al. 1999). This approach was derived for sensor arrays where each sensor's signal is proportional to the amount of vapor sorbed by a polymer on the sensor surface. In this case, the response is proportional to the partition coefficient, K, and the concentration of the vapor in the gas phase, Cv, where K is the ratio of the concentration of vapor in the sorbent polymer phase, Cs, to Cv.

The Chief Operating Officer Concept and its Potential Use as a Strategy to Improve Management at the Department of Homeland Security
Correspondence issued by the General Accounting Office with an abstract that begins "In a May 18, 2004 letter, the Chairman of the House Select Committee on Homeland Security observed that many management and integration challenges remain at the Department of Homeland Security (DHS) and to strengthen the departmentwide reforms and transformation underway at DHS the Select Committee is considering options such as the Chief Operating Officer (COO) concept to help address these challenges. This letter describes the roles and responsibilities of an effective COO and presents certain options that could serve to strengthen and streamline management functions in a department as large and diverse as DHS. As agreed, we have summarized our reports on the COO concept, organizational transformation, as well as DHS's management and transformation challenges."

China-U.S. Relations
This report discusses the background information and most recent development in U.S.-China relations since mid-1996. Since the early 1990s, U.S.-China relations have followed an uneven course, with modest improvements overshadowed by various recurring difficulties and setbacks. Longstanding bilateral difficulties have included U.S. problems with the PRC’s worsening human rights record, growing tensions over the PRC’s southern military build-up opposite Taiwan and Taiwan’s political status, and continued controversy over allegations of Chinese proliferation of weapons to unstable regimes.

China’s Currency: Economic Issues and Options for U.S. Trade Policy
The continued rise in China’s trade surplus with the United States and the world, and complaints from U.S. manufacturing firms and workers over the competitive challenges posed by Chinese imports have led several Members to call for a more aggressive U.S. stance against certain Chinese trade policies they deem to be unfair. This report examines China's currency policy its implications.

Civil Service Retirement Bills in the 106th Congress
Among the civil service retirement issues addressed in bills introduced thus far in the 106th Congress are the correction of retirement coverage errors for federal employees assigned to the wrong retirement system; immediate eligibility for federal employees to participate in the Thrift Savings Plan (TSP); improved portability of pension benefits; and repeal of the temporary increase in employee retirement contributions that was mandated by the Balanced Budget Act of 1997. Other bills would expand TSP eligibility to include members of the armed services; improve pension coverage for temporary and part-time federal employees; and designate several categories of federal employees as law enforcement officers for purposes of determining their retirement benefits.

Clean Water Act Issues in the 108th Congress
Prospects for legislative initiatives to comprehensively amend the Clean Water Act have stated for some time over whether and exactly how to change the law, and Congress has recently focused legislative attention on narrow bills to extend or modify selected Clean Water Act programs, rather than taking up comprehensive proposals. This report contains information on the issues and actions regarding the Clean Water Act addressed in the 108th Congress.

Coast Guard Deepwater Program: Background and Issues for Congress
The Deepwater program is a $24-billion, 25-year acquisition program to replace or modernize 93 Coast Guard ships and 207 Coast Guard aircraft. The Coast Guard’s FY2006 budget requests $966 million for the program. Some Members of Congress have strongly criticized the Deepwater program on several grounds. The House version of H.R. 2360, the FY2006 Department of Homeland Security (DHS) appropriations bill, reduces the FY2006 Deepwater funding request to $500 million; the Senate version reduces it to $905.6 million.
