Magnetic resonances in atomic vapor excited by a mechanical resonator

December 1, 2006
Author(s)
Ying-ju Wang, Matt Eardley, Svenja A. Knappe, John Moreland, Leo W. Hollberg, John E. Kitching
We demonstrate a direct resonant interaction between the mechanical motion of a mesoscopic resonator and the spin degree of freedom of a sample of neutral atoms in the gas phase. This coupling, mediated by a magnetic particle attached to the tip of the

NIST Calibration of a Neutron Spectrometer ROSPEC

December 1, 2006
Author(s)
Craig Heimbach
A neutron spectrometer, ROSPEC, was acquired for use in the measurement of NIST calibration neutron fields. The spectrometer included options for the measurement of low and high energy neutrons, for a measurement range from thermal neutron up to 16 MeV

NIST Time and Frequency Bulletin

December 1, 2006
Author(s)
Eyvon Petty
The Time and Frequency Bulleting provides information on performance of time scales and avariety of broadcasts (and related information) to users of the NIST services.

NMR Analysis of Rhodopsin-Transducin Interactions

December 1, 2006
Author(s)
Kevin Ridge, John Marino, T Ngo, Eva Ramon, D M. Brabazon, N G. Abdulaev
Heterotrimeric G-protein activation by an agonist-stimulated G-protein coupled receptor (R*) requires the propagation of structural signals from the receptor interacting surfaces to the guanine nucleotide-binding pocket. Employing high-resolution NMR

On the Ignition of Fuel Beds by Firebrands.

December 1, 2006
Author(s)
Samuel L. Manzello, Thomas G. Cleary, John R. Shields, Jiann C. Yang
An experimental apparatus has been built to investigate the ignition of fuel beds as a result of impact with burning firebrands. The apparatus allowed for the ignition and deposition of both single and multiple firebrands onto the target fuel bed. The

Project Team 4, the 2000-2005 Reference Standards Committee of the USP Council of Experts and Its Advisory Panel, USP Staff, Consultant: Official USP Reference Standards: Metrology Concepts, Overview, and Scientific Issues and Opportunities

December 1, 2006
Author(s)
Reenie M. Parris
The United States Pharmacopeia (USP) is a private standards-setting body created in 1820 by practitioners who wished to promote the quality of therapeutic products in commerce. The principal product of USP, then and now, is the United States Pharmacopeia

Remote Time Calibrations via the NIST Measurement and Analysis Service

December 1, 2006
Author(s)
Michael A. Lombardi, Andrew N. Novick
NIST now offers a new remmote calibration service desinged to assist laboratories who maintain an accurate local time standard. The service monitors the local time standard by continuously comparing it to the national time standard, and reports the

Standards and Measurements for Assessing Bone Health

December 1, 2006
Author(s)
Herbert S. Bennett, Andrew Dienstfrey, Thomas Fuerst, Lawrence T. Hudson, Tammy L. Oreskovic, John Shepherd
This paper reports and discusses the results of the recent ISCD-NIST USMS Workshop on Standards and Measurements for Assessing Bone Health. The purpose of the Workshop was to assess the status of efforts to standardize and compare results from dual-energy

Synthetic Incoherence Via Scanned Gaussian Beams

December 1, 2006
Author(s)
Zachary H. Levine
Tomography, in most formulations, requires an incoherent signal. For a conventional transmission electron microscope, the coherence of the beam often results in diffraction effects which limit the utility of a tilt series with conventional tomographic

Terminology for High-Speed Sampling-Oscilloscope Calibration

December 1, 2006
Author(s)
Dylan Williams, Tracy S. Clement, Paul D. Hale, Andrew Dienstfrey
We discuss procedures for calibrating high-speed sampling oscilloscopes at the National Institute of Standards and Technology, and the terminology associated with those calibrations. The discussion clarifies not only the calibration procedures, but how to
