Through-Thickness Texture Inhomogeneity in a Recrystallized Al-Mg Alloy

March 1, 2005
Author(s)
J -. Liu, Stephen W. Banovic, Frank S. Biancaniello, Rodney D. Jiggetts
Through-thickness texture of a rolled and recrystallized Al-Mg continuous cast alloy was examined using electron backscattered diffraction. Results showed the recrystallization texture through thickness of the sheet was inhomogeneous with Cube 001}

Toward Data Standards for Proteomics Data

March 1, 2005
Author(s)
Veerasamy Ravichandran, Ram D. Sriram
Biologists have traditionally worked with relatively small data sets and shared results only with others working on similar biological systems. With the advent of genomics, and now proteomics, they are faced with exponentially growing sets of highly inter

Understanding Failure Response in Service Discovery Systems

March 1, 2005
Author(s)
Kevin L. Mills, Stephen Quirolgico, Christopher E. Dabrowski
Service discovery systems enable distributed components to find each other without prior arrangement, to express capabilities and needs, to aggregate into useful compositions, and to detect and adapt to changes. First-generation discovery systems can be

Web-Based 3D Visualization in a Digital Library of Mathematical Functions

March 1, 2005
Author(s)
Qiming Wang, Bonita V. Saunders
The National Institute of Standards and Technology (NIST) is developing a digital library of mathematical functions to replace the widely used National Bureau of Standards Handbook of Mathematical Functions published in 1964 [1]. The NIST Digital Library

X-ray Absorption Spectroscopy to Probe Surface Composition and Surface Deprotection in Photoresist Films

March 1, 2005
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 M. Goldfarb, M Angelopoulos
We utilize near edge x-ray absorption fine structure spectroscopy (NEXAFS) to provide chemical insight into surface chemical effects in model photo-resist films. First, NEXAFS was used to examine the resist/air interface including surface segregration of a

Detailed Study and Projection of Hard Breakdown Evolution in Ultra-Thin Gate Oxides

February 28, 2005
Author(s)
John S. Suehle, Baozhong Zhu, Yuan Chen, J B. Bernstein
The mechanism responsible for post soft-breakdown leakage current increase in ultra-thin oxides depends on the nature of the conducting filament formed at the instant of dielectric breakdown. The conductance of the filament formed during soft breakdown has

The GOES Time Code Service, 1974 - 2004: A Retrospective

February 27, 2005
Author(s)
Michael A. Lombardi, D. W. Hanson
After nearly 30 years of continuous operation, NIST ended its Geostationary Operational Environmental Satellites (GOES) time code service at 0 hours, 0 minutes Coordinated Universal Time (UTC) on January 1, 2005. This event marked the end of an important

Simultaneous state measurement of coupled Josephson phase qubits

February 25, 2005
Author(s)
Robert McDermott, Raymond Simmonds, Matthias Steffen, Ken B. Cooper, Katarina Cicak, Kevin Osborn, Seongshik Oh, David P. Pappas, John M. Martinis
One of the many challenges of building a scalable quantum computer is singleshot measurement of all the quantum bits (qubits). We have used simultaneous single-shot measurement of coupled Josephson phase qubits to directly probe interaction of the qubits

Characterization of Ordered Mesoporous Silica Films Using Small Angle Neutron Scattering and X-Ray Porosimetry

February 23, 2005
Author(s)
B D. Vogt, R A. Pai, Hae-Jeong Lee, R C. Hedden, Christopher L. Soles, Wen-Li Wu, Eric K. Lin, Barry J. Bauer, J J. Watkins
Ordered mesoporous silica films were synthesized using pre-organized block copolymer templates in supercritical carbon dioxide. Poly(ethylene oxide-block-propylene oxide-block-ethylene oxide), PEO-b-PPO-b-PEO, films doped with p-toluenesulfonic acid (p TSA

A chip-scale atomic clock based on 87 Rb with improved frequency stability

February 21, 2005
Author(s)
Svenja A. Knappe, P Schwindt, V Shah, Leo W. Hollberg, John E. Kitching, Li-Anne Liew, John Moreland
We demonstrate a microfabricated atomic clock physics package based on coherent population trapping (CPT) of 87Rb atoms. The package occupies a volume of 12 mm 3 and requires 195 mW of power to operate. Compared to a previous microfabricated clock exciting

Effect of Uniaxial Strain on the Surface Roughness of Pure MG and MG-AZ31 Alloy

February 21, 2005
Author(s)
Mark R. Stoudt, A -. Munitz, Stephen W. Banovic, Richard J. Fields
Pure Mg and Mg AZ31 alloy samples were deformed in uniaxial tension and the resultant surface topographies were characterized with optical microscopy, scanning laser confocal microscopy (SCLM) and scanning electron microsopy (SEM) techniques. Initial

Measurement of detector nonlinearity at 193 nm

February 20, 2005
Author(s)
Holger Laabs, Darryl A. Keenan, Shao Yang, Marla L. Dowell
We have developed a measurement system based on a correlation method to characterize the nonlinearity of a detector's response over a large range of laser pulse energy. The system consists of an excimer-laser source, beam-shaping optics, a beam splitter, a

Frequency modulation of spin-transfer oscillators

February 18, 2005
Author(s)
Matthew Pufall, William Rippard, Shehzaad F. Kaka, Thomas J. Silva, Stephen E. Russek
Spin-polarized dc electric current flowing into a magnetic layer can induce precession of the magnetization at a frequency that depends on current. We show that addition of an ac current to this dc bias current results in a frequency modulated (FM)

Random decoupling schemes for quantum dynamical control and error suppression

February 18, 2005
Author(s)
Lorenza Viola, Emanuel Knill
We introduce a general control-theoretic setting for random dynamical decoupling, applicable to quantum , engineering of both closed-and open-system dynamics. The basic idea is to randomize the operations of the controller, by designing the control
