The HI0073/HI0074 Protein Pair From Haemophilus Influenzae is a Member of a New Nucleotidyltransferase Family: Structure, Sequence Analyses, and Solution Studies

February 1, 2003
Author(s)
C Lehmann, Kap Lim, V R. Chalamasetty, W Krajewski, E Melamud, Andrey Galkin, A Howard, Z Kelman, Prasad T. Reddy, A Murzin, O Herzberg
The crystal structure of HI0074 from Haemophilus influenzae, a protein of unknown function, has been determined at a resolution of 2.4 . The molecules form an up-down four-helix bundle, and associate into homodimers. The fold is most closely related to the

The Proving Ring

February 1, 2003
Author(s)
Simone L. Yaniv
In this homepage, the history, construction, design and calibration of proving rings are given. The importance of force measurement and the principles involved are described.

ThermoML - an XML-Based Approach to Standardize Storage and Exchange of experimental and Critically Evaluated Thermophysical and Thermochemical Property Data. 1. Experimental Data

February 1, 2003
Author(s)
Michael D. Frenkel, Robert D. Chirico, Vladimir Diky, Qian Dong, Svetlana Frenkel, Paul R. Franchois, K N. Marsh, R C. Wilhoit, D L. Embry, T L. Teague
sic principles, scope, and description of all structural elements of ThermoML are discussed. ThermoML is an XML-based approach to standardize storace and exchange of experimental and critically evaluated thermophysical and thermochemical property data

Tuning P-Wave Interactions in an Ultracold Fermi Gas of Atoms

February 1, 2003
Author(s)
C A. Regal, J L. Ticknor, J L. Bohn, D S. Jin
We have measured a p-wave Feshbach resonance in a single-component, ultracold Fermi gas of 40K atoms. We have used this resonance to enhance the normally suppressed p-wave collision cross-section to values larger than thebackground s-wave cross-section

Ultracold Collision Properties of Metastable Alkaline-Earth Atoms

February 1, 2003
Author(s)
A Derevianko, S. G. Porsev, Svetlana A. Kotochigova, Eite Tiesinga, Paul S. Julienne
Ultra-cold collisions of spin-polarized Mg, Ca, and Sr in the metastable 3P2 excited state are investigated. We show the existence of purely long-range potentials, determine the scattering length, and estimate the collisional loss rate as a function of

Uncertainties in Interpolated Spectral Data

February 1, 2003
Author(s)
J L. Gardner
Interpolation is often used to improve the accuracy of integrals over spectral data convolved with various response functions or power distributions. Formulae are developed for propagation of uncertainties through the interpolation process, specifically

X-Ray Absorption Spectroscopy to Probe Interfacial Issues in Photolithography

February 1, 2003
Author(s)
Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, Daniel A. Fischer, S Sambasivan, Eric K. Lin, Ronald L. Jones, Christopher Soles, Wen-Li Wu, D L. Goldfarb, M Angelopoulos
Control of the shape, critical dimension (CD), and roughness is critical for the fabrication of sub 100 nm features, where the CD and roughness budget are approaching the molecular dimension of the resist polymers1. Here we utilize near edge X-ray

Automated Security Self-Evaluation Tool Technical Documentation, Version 1.03

January 31, 2003
Author(s)
Mark McLarnon, Marianne M. Swanson
The Automated Security Self-Evaluation Tool (ASSET) automates the process of completing a system self-assessment. ASSET will assist organizations in completing the self-assessment questionnaire contained in NIST Special Publication (Special Publication)

Estimating the Work in Integer Partitioning

January 31, 2003
Author(s)
April Andreas, Isabel M. Beichl
For a given set of numbers, the integer partitioning problem is to divide the numbers into two groups, so that the sums of the numbers in each group differ by the smallest amount possible. In a balanced perfect partition, the sums differ by only zero or

Measuring Resin Temperature During Extrusion Using a Fluorescence Technique

January 30, 2003
Author(s)
Anthony J. Bur, S C. Roth, D W. Baugh, K A. Koppi, M A. Spalding, J Gunderson, W C. Buzanowski
We have used a temperature sensitive fluorescent dye, doped into polycarbonate, to monitor the true resin temperature during extrusion processing. The fluorescent dye, perylene, was doped into the polycarbonate at very low concentration. We apply this

NIST CFIT: Testing Disk Imaging Tools

January 27, 2003
Author(s)
James R. Lyle
There is a critical need in the law enforcement community to ensure the reliability of computer forensic tools. A capability is required to ensure that forensic software tools consistently produce accurate and objective test results. The goal of the

Experimental Demonstration of a Technique to Generate Arbitrary Quantum Superposition States of a Harmonically Bound Spin-1/2 Particle

January 24, 2003
Author(s)
A Ben-kish, B M. Demarco, V Meyer, Mary A. Rowe, Joseph W. Britton, Wayne M. Itano, Branislav M. Jelenkovic, Christopher Langer, Dietrich Leibfried, Till P. Rosenband, David J. Wineland
Using a single, harmonically trapped 9Be+ ion, we experimentally demonstrate a technique for generation of arbitrary states of a two-level particle confined by a harmonic potential. Rather than engineering a single Hamiltonian that evolves the system to a

SCUBA-2: a large format submillimeter camera on the James Clerk Maxwell Telescope

January 20, 2003
Author(s)
Wayne Holland, William Duncan, Kent D. Irwin, Anthony Walton, Peter Ade, Ian Robson
SCUBA-2 is a second generation, wide-field submillimeter camera under development for the James Clerk Maxwell Telescope. With over 12,000 pixels, in two arrays, SCUBA-2 will map the submillimeter sky 1000 times faster than the current SCUBA instrument to
