1 H- 31 P CPMG-Correlated Experiments for the Assignment of Nucleic Acids

November 14, 2001
Author(s)
B. Luy, John Marino
Phosphorus (31P) nuclear magnetic resonance (NMR) spectroscopy can provide important information about the structure and dynamics of nucleic acids in solution. The application of 31P NMR, however, often requires the difficult task of resolving and

Noise Parameter Uncertainties from Monte Carlo Simulations

November 8, 2001
Author(s)
James P. Randa, Wojciech Wiatr
We present results for uncertainties in noise-parameter measurements, obtained using a Monte Carlo simulation of the measurements. Sets of data were generated to simulate measurements on a low-noise amplifier, with given uncertainties in the underlying

The 2001 Annual Meeting of the American Crystallographic Association

November 6, 2001
Author(s)
Alan D. Mighell
The annual meeting of the American Crystallographic Association was held in Los Angeles, California, July 2126, 2001. The scientific sessions and the exhibit show were held in the Westin Bonaventure Hotel in downtownLos Angeles. The meeting was well

Excellent charge offset stability in a Si-based single-electron tunneling transistor

November 5, 2001
Author(s)
Neil M. Zimmerman, W H. Huber, Akira Fujiwara, Yasuo Takahashi
We have measured the long-term drift and the short-term 1/f noise in the charge offset Q0(t) in two Si-based single-electron tunneling transistors (SETTs). In contrast to metal-based SETTs, these devices show excellent charge stability, drifting by less

1,2-Pentadiene Decomposition

November 1, 2001
Author(s)
J Herzler, Jeffrey A. Manion, Wing Tsang
1,2-Pentadiene has been decomposed in single pulse shock tube experiments. There appear to be a large number of parallel decomposition and isomerization channels. The following rate expressions for isomerization in the temperature range 1100 K-1250 K and 2

2 Combinatorial Methods Polymer Science: Synthesis and Characterization

November 1, 2001
Author(s)
J C. Meredith, A P. Smith, Alamgir Karim, Eric J. Amis
Combinatorial methodologies offer the ability to efficiently measure relevant chemical and physical properties over lare regimes of varible space. We review recent work in the development of combinatorial methods for polymer synthesis and characterization

A 2.4mm Coaxial Power Standard at NIST

November 1, 2001
Author(s)
Thomas P. Crowley, Fred R. Clague
A microcalorimeter and bolometer transfer standard are used as a national standard for microwave power from 50 MHz to 50 GHz. the microcalorimeter is used to determine the efficiency of the bolometric transfer standards and is similar to an existing Type N

Amorphous Calcium Phosphate

November 1, 2001
Author(s)
Laurence C. Chow, E D. Eanes
Amorphous structures represent about 20% of the 60 or so different mineral types formed by the action of living organisms. Among these biogenic amorphous minerals, those that are composed principally of calcium and phosphate are most abundant in the teeth

AutoBid: System for Police Patrol Selection.

November 1, 2001
Author(s)
S F. Weber, Amy S. Rushing
AutoBid is designed to help police fleet administrators select the patrol vehicle that is best suited to the needs of their department. The system is based on vehicle performance test data for police patrol package models published annually by the Michigan

CFD Modeling and Comparison with Data for the NIST Reference Spray Combustor

November 1, 2001
Author(s)
D S. Crocker, J F. Widmann, Cary Presser
Validation of computational fluid dynamics (CFD) predictions for spray combustion application has been a challenging task due to difficulties in both modeling and experimental measurements. However, validation is considered to be an essential exercise for

Characterization of 2.5 Inch Diameter Bulk GaN Grown from Melt-Solution

November 1, 2001
Author(s)
V Soukhoveev, V Ivantsov, Y Melnik, Albert Davydov, Denis Tsvetkov, K Tsvetkova, I Nikitina, A Zubrilov, A Lavrentiev, Vladimir A. Dmitriev
Crystal growth from a melt or melt-solution is a widely accepted technique for industrial-scale production of important semiconductor materials. Recently we have demonstrated 50 mm diameter GaN crystals grown by melt-solution technique [1]. The crystals

Commemorative Issue for Professor Simon H. Bauer I: Editorial Comment

November 1, 2001
Author(s)
Wing Tsang, Robert E. Huie, Jeffrey A. Manion
The next two issues of the International Journal of Chemical Kinetics are dedicated to Prof. Simon H. Bauer on the occasion of his 90th birthday. These issues contain a number of papers by his students and colleagues who have built on his pioneering

Computer Forensics Guidance

November 1, 2001
Author(s)
G E. Fisher
This ITL Bulletin describes two projects in the computer forensics arena and provides guidance on the use of the products developed from them. The first project, the National Software Reference Library (NSRL), describes a database of known file
