NIST Special Database #28

September 1, 2004
Author(s)
Reference Data Set V. National software reference library
The goal of this document is to help W3C editors write better specifications, by making a specification easier to interpret without ambiguity and clearer as to what is required in order to conform. It focuses on how to define and specify conformance. It

NIST's Logistics Integration Solutions

September 1, 2004
Author(s)
Sharon J. Kemmerer
The NIST Manufacturing Interoperability Program staff has years of experience developing standards, validating solutions, and providing interoperability results in the field of manufacturing. Building on this experience, NIST can: (1) Work with industry to

On the Feasibility of Single Molecule Detection of the Guanosine-Analogue, 3-MI

September 1, 2004
Author(s)
J E. Sanabia, Lori S. Goldner, P A. Lacaze, M E. Hawkins
We present UV fluorescence fluctuation correlation spectroscopy (FCS) measurements on the guanosine-analog 3-MI [3-Methyl-8-(2-deoxy- -D-ribofuranosyl)isoxanthopterin], a pteridine widely used in studies of DNA binding and dynamics. We measure the photon

Oxidative DNA Damage: Induction, Repair and Significance

September 1, 2004
Author(s)
M D. Evans, Miral M. Dizdar, M S. Cooke
The generation of reactive oxygen species may be both beneficial to cells, performing a function in inter- and intra-cellular signaling, and detrimental, modifying cellular bimolecules, accumulation of which has been associated with numerous diseases. Of

Precision Feshbach Spectroscopy of Ultracold Cs-2

September 1, 2004
Author(s)
C Chin, Vladan Vuletic, A J. Kerman, S G. Chu, Eite Tiesinga, P J. Leo, Carl J. Williams
We have observed > 60 magnetic field-induced Feshbach resonances in ultra-cold collisions of ground-state cesium atoms. The resonances have been detected using three different scattering processes: elastic collisions, inelastic collisions and radiative

Rate Adaptive Video Transmission Over Ad-Hoc Networks

September 1, 2004
Author(s)
Hamid Gharavi, K Ban
In mobile ad-hoc network environments where the network topology is expected to change considerably, providing reliable video communications is a challenging task. This paper is mainly concerned with developing a packet control mechanism to reduce bursts

Real-Time Monitoring of Polymer Nanocomposites Composition during Extrusion Compounding

September 1, 2004
Author(s)
Rick D. Davis, Jeffrey W. Gilman, Anthony J. Bur, M M. McBrearty, P R. Start, Young J. Lee
Dielectirc spectroscopy was conducted during extrusion processing of polyamide-6 (PA6) and layered silicate/polyamide-6 manocomposites. Dielectric dispersion parameteers were identified that appear sensitive to layered silicate concentration and degree of

Sooting Behavior of Ethanol Droplet Combustion at Elevated Pressures Under Microgravity Conditions

September 1, 2004
Author(s)
B D. Urban, K Kroenlein, A Kazakov, F L. Dryer, A Yozgatligil, M Y. Choi, Samuel Manzello, K O. Lee, R Dobashi
Liquid ethanol is widely used in practical fuels as a means to extend petroleum-derived resources or as a fuel additive to reduce emissions of carbon monoxide from spark ignition engines. Recent research has also suggested that ethanol and other oxygenates

Paul A. Williams, Gordon W. Day
This digest is made up of technical papers presented at the 13th biennial Symposium on Optical Fiber Measurements (SOFM 2004)in Boulder, Colorado, September 28-30, 2004. Paper categories include wavelength metrology, nonlinear measurements, fiber

Template Fabrication of Protein-Functionalized Gold-Polypyrrole-Gold Segmented Nanowires

September 1, 2004
Author(s)
R M. Hernandez, Lee J. Richter, Stephen Semancik, Stephan J. Stranick, Thomas E. Mallouk
Gold nanowires containing protein-modified poly(pyrrole) (Ppy) junctions were synthesized electrochemically using porous aluminum oxide as a template. The effects of the conditions of electrochemical synthesis on Ppy growth and protein (avidin or
