An XML Namespace for IUPAC

July 1, 2002
Author(s)
Stephen E. Stein
The author presented two talks at the IUPAC/CAS conference of Chemical identifiers and XML in Chemistry, on July 1, 2002 in Columbus Ohio. He will be sending PowerPoint presentations of these talks, both concerning on-going projects at NIST, to IUPAC for

Anatomy of Spin-Transfer Torque

July 1, 2002
Author(s)
Mark D. Stiles, A Zangwill
Spin-transfer torques occur in magnetic heterostructures because the transverse component of a spin current that flows from a non-magnet into a ferromagnet is absorbed at the interface. We demonstrate this fact explicitly using free electron models and

Autonomous Mobility for the Demo III Experimental Unmanned Vehicles

July 1, 2002
Author(s)
Alberto Lacaze, Karl Murphy, M DelGiono
This paper will describe the autonomous mobility controller used under the U.S. Army sponsored Demo III eXperimental Unmanned Vehicle (XUV) project. The controller is designed for avoiding obstacles and traversing highly unstructured outdoor environments

Bridging the Gap Between Structure and Properties in Nano-Particle Filled Polymers

July 1, 2002
Author(s)
Erik K. Hobbie, Francis W. Starr, Jack F. Douglas, Charles C. Han
On May 29-30, 2002, a workshop on polymer nanocomposites was held at NIST in Gaithersburg, Maryland. The workshop was entitled Bridging the Gap Between Structure and Properties in Nanoparticle-Filled Polymers and focused primarily on the interrelation

Chemical Ionization of Saturated Hydrocarbons Using Organometallic Ion Chemistry

July 1, 2002
Author(s)
H M. Byrd, Charles M. Guttman, D P. Ridge
Introduction: The potential for quick and direct measurement of chemical composition, absolute molecular mass (MM), MM distribution of linear and branched saturated polyolefins makes mass spectrometry especially attractive to the polymer industry. However

Community-Scale Fire Spread

July 1, 2002
Author(s)
Ronald G. Rehm, Anthony P. Hamins, Howard R. Baum, Kevin B. McGrattan, D D. Evans
This paper addresses community-scale fires, which have also been called urban/wildland interface or intermix fires. These fires arise when wildlandfires invade the built environment and attack structures as well as wildland fuels. The prediction of the

Comparison of Measured Optical Image Profiles of Silicon Lines with Two Different Theoretical Models

July 1, 2002
Author(s)
Richard M. Silver, Ravikiran Attota, Michael T. Stocker, Jay S. Jun, Egon Marx, Robert D. Larrabee, B Russo, M P. Davidson
In this paper we describe a new method for the separation of too-induced measurement errors and sample-induced measurement errors. We apply the method to standard overlay target configurations. This method is used to separate the effects of the tool and

Creation of a Molecular Condensate by Dynamically Melting a Mott Insulator

July 1, 2002
Author(s)
D Jaksch, V Venturi, J I. Cirac, Carl J. Williams, W.H. Zoller
We propose creation of a molecular Bose-Einstein condensate (BEC) by loading an atomic BEC into an optical lattice and driving it into a Mott insulator (MI) phase with exactly two atoms per site. Molecules in a MI state are then created under well defined

Crystal Structure of Ba 27 Fe 16 Ti 33 O 117

July 1, 2002
Author(s)
T Siegrist, Terrell A. Vanderah, C Svensson, Robert S. Roth
Single-crystal X-ray diffraction studies indicate that the compound Ba 27Fe 16Ti 33O 117- crystallizes in the rhombohedral space group R-3m, with a hexagonal unit cell a=5.7400(8) , c=127.11(3) ; Z=1.5. The arrangement may be described as a 54-layer (54L)

Direct Measurement of the Reaction Front in Chemically Amplified Photoresists

July 1, 2002
Author(s)
Eric K. Lin, Sushil K. Satija, Wen-Li Wu, Christopher L. Soles, D L. Goldfarb, B C. Trinque, S D. Burns, Ronald L. Jones, Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, M Angelopoulos, C G. Willson
The continuing drive by the semiconductor industry to fabricate smaller structures with photolithography will soon require dimensional control at length scales, (2 to 5) nm, comparable to the size of the polymeric molecules in the materials used to pattern

Document Understanding Conferences Website

July 1, 2002
Author(s)
Ellen M. Voorhees
This paper demonstrates that, for large-scale tests, the match and non-match similarity scores have no specific underlying distribution function. The forms of these distribution functions require a nonparametric approach for the analysis of the fingerprint

Dynamic Range Limitations in Phase Doppler Interferometry Measurements

July 1, 2002
Author(s)
J F. Widmann, Cary Presser, Stefan D. Leigh
It has been well established that the dynamic range of phase Doppler interferometry (PDI) size measurements is limited by the photomultiplier tubes (PMT). A statistical method is presented to overcome this limitation by combining data sets collected over

Dynamics in a Two-Level Atom Magneto-Optical Trap

July 1, 2002
Author(s)
X Xu, T Loftus, M J. Smith, John L. Hall, Alan Gallagher, Jun Ye
Alkaline earth metal atoms present an ideal platform for exploring magneto-optic trap (MOT) dynamics, enabling unique and definitive tests of laser cooling and trapping mechanisms. We have measured the trapping beam intensity, detuning, magnetic-field
