Influence of Solvent on Dynamics and Stability of a Protein

September 1, 2002
Author(s)
G Caliskan, A Kisliuk, A M. Tsai, Christopher Soles, Alexei Sokolov
Proteins are often dissolved in viscous glass-forming solvents to provide thermal stability and preserve biochemical activity. However, the mechanisms by which this preservation is achieved are unclear. This issue of biopreservation is undoubtedly affected

Information Access: Do You Mind?

September 1, 2002
Author(s)
John V. Cugini
Successful execution of many information-based tasks depends crucially on contextual knowledge. Language processing is particularly sensitive to context, and I will concentrate on it in this extended abstract as the example par excellence of knowledge

Interface-Driven Model-Based Generation of Java Test Drivers

September 1, 2002
Author(s)
Mark Blackburn, Robert Busser, Aaron Nauman, Ramaswamy Chandramouli
This paper extends prior work in model-based verification and describes interface-driven analysis that combines with a requirement model to support automated generation of Java test scripts. It describes concepts of models and test driver mappings using

Kinetic Minimum-Power Routing and Clustering in Mobile Ad-Hoc Networks

September 1, 2002
Author(s)
Camillo Gentile, R E. Van Dyck, J Haerri
We have previously developed a distributed routing algorithm which minimizes the number of overhead messages necessary to maintain the minimum-power multi-hop routes in a mobile ad-hoc network, assuming a piece-wise linear model for the motion of the nodes

Knowledge Engineering for Real-Time Intelligent Control

September 1, 2002
Author(s)
John Evans, Elena R. Messina, James S. Albus, Craig I. Schlenoff
The key to real-time intelligent control lies in the knowledge models that the system contains. Three main classes of knowledge are identified: parametric, geometric/iconic, and symbolic. Each of these classes provides unique perspectives and advantages

Magnetic Properties of Ultrathin Laminated Co/Cu Films Prepared by Electrodeposition

September 1, 2002
Author(s)
M Shima, L Salamanca-Riba, Thomas P. Moffat, Robert D. McMichael
The magnetic properties of a series of electrodeposited [Co(x ML)/Cu(17 ML)]100 multilayers have been examined as a function of the cobalt layer thickness. The multilayers were grown on Si(100)covered with a highly textured Cu(100) seed alyer. Films with a

Mass Absorption Coefficient of Tungsten and Tantalum

September 1, 2002
Author(s)
Zachary H. Levine
Web page for the Computational Material Science Network(administered at U. Washington) based on the following WERB-approvedmanuscripts:Z.~H.~Levine, S.~Grantham, C.~Tarrio,D.~J.~Paterson, I.~McNulty, T.~M.~Levin,A.~L.~Ankudinov, and J.~J.~Rehr,``Mass

Measurement of Lithographic Overlay by Light-Scattering Ellipsometry

September 1, 2002
Author(s)
Thomas A. Germer
We demonstrate a measurement of lithographic overlay using light scattering ellipsometry. In the limit of small amplitude surfactopography, the polarization of light scattered by the two interfaces of a dielectric film can be decomposed into the roughness

Mobile 3D Visualization for Construction

September 1, 2002
Author(s)
Robert R. Lipman
Until recently, visualization of 3D models required computational resources available only on desktop computers in office environments. With the advance of technology, it is now possible to visualize substantial 3D models on mobile handheld computers in

NbN Film Development for PHEB Devices

September 1, 2002
Author(s)
Eyal Gerecht, V. A. Bhupathiraju, Erich N. Grossman, Jeffrey W. Nicholson, Fernando Rodriguez-Morales, Dazhen Gu, Sigfrid Yngvesson
We have developed a process for fabricating a thin NbN film at the National Institute of Standards and Technology in Boulder, CO. A two-fold approach can be taken. The first is to maximize the critical temperature of the superconducting device (growing

New NIST-Traceable Standards for Calibration and Validation of DSC

September 1, 2002
Author(s)
Donald G. Archer
NIST is generating a new suite of Standard Reference Materials for calibration and validation of Differential Scanning Calorimetry (DSC). Calibration and validation of DSC measurement methods require having known property values of some reference materials

NIST Data Gateway, 2002 Version

September 1, 2002
Author(s)
D M. Blakeslee, Angela Y. Lee, A J. Belsky, John E. Fuller III
The NIST Data Gateway is a Web portal that provides easy access to NIST scientific and technical data, which cover a broad range of substances and properties from many different scientific disciplines. Users can search for specific keywords, properties

NIST RM (Reference Material) 8240/8250 Standard Bullets and Casings Project

September 1, 2002
Author(s)
Jun-Feng Song, Theodore V. Vorburger, Susan M. Ballou, M Ols
The NIST RM (Reference Material) 8240/8250 Standard Bullets and Casings Project aims to support the National Integrated Ballistics Information Network (NIBIN) in the U.S. Two prototype standard bullets were developed in 1998 with all six lands manufactured

Noise Temperature for Nb DHEB Mixer Receiver for Far-Infrared Spectroscopy

September 1, 2002
Author(s)
Eyal Gerecht, Carl D. Reintsema, Erich N. Grossman, A. L. Betz, R. T. Boreiko
We are reporting a noise temperature measured on a diffusion-cooled hot electron bolometeric (DHEB) mixer designed for a heterodyne focal plane array to study lines with frequencies of 2 THz and above. Our fabrication process utilizes selective ion milling

Normal Mode Mixing and Ferromagnetic Resonance Linewidth

September 1, 2002
Author(s)
A B. Kunz, Robert D. McMichael
This spin wave modes for a uniform film are perturbed by the inclusion of inhomogeneities into the system. The resulting perturbed Hamiltonianis diagonalized to create a new set of spin waves modes. The effect of the strength of the perturbations is

Optical Reflectance of Metallic Coatings: Effect of Aluminum Flake Orientation

September 1, 2002
Author(s)
Li Piin Sung, Maria E. Nadal, M E. McKnight, Egon Marx, B Laurenti
The orientation of platelet-like pigments in coatings is affected by the processing conditions resulting in appearance variations of the final product. A set of aluminum-flake pigmented coatings having different flake orientations was pre-pared using
