Toward Spin Squeezing with Trapped Ions

September 23, 2010
Author(s)
John J. Bollinger, Hermann Uys, Michael Biercuk, Joseph W. Britton
Building robust instruments capable of making interferometric measurements with precision beyond the standard quantum limit remains an important goal in many metrology laboratories. We describe here the basic concepts underlying spin squeezing experiments

A Framework for Multi-Resolution Modeling of Sustainable Manufacturing

September 22, 2010
Author(s)
Sanjay Jain, Deogratias Kibira
This paper proposes a multi-resolution framework for application of system dynamics modeling to sustainable manufacturing. Sustainable manufacturing involves interaction of four complex systems namely manufacturing, environmental, financial, and social

Peer Review Report 2010

September 22, 2010
Author(s)
Thomas A. Siewert, Robert Smith, Theresa Bell, Joseph D. McColskey, Richard J. Fields
The Pipeline and Hazardous Materials Safety Administration s Pipeline Safety Research and Development (R&D) Program held a structured peer review of active research projects in April 2010. The peer review panel consisted of twelve government and industry

On-Board Signal Integrity for GPS

September 21, 2010
Author(s)
Marc A. Weiss, Pradipta Shome, Ron Beard
The elements of a space-based integrity approach are to monitor the signals on-board the satellite, such that signal performance can be maintained well within desired integrity limits. These elements include 1) a system for monitoring multiple atomic

CMSD: A Model Supporting Manufacturing and Simulation Application Integration

September 20, 2010
Author(s)
Frank H. Riddick, Yung-Tsun T. Lee
Standard representations for key manufacturing entities could help reduce the costs associated with simulation model construction and data exchange between simulation and other software applications. This change would make the use of simulation technology

lSPR Study of DNA Wrapped Single Wall Carbon Nanotube (ssDNA-SWCNT) Adsorption on a Model Biological (Collagen) Substrate

September 20, 2010
Author(s)
Jung Jin Park, Jeffrey Fagan, JiYeon Huh, Kalman D. Migler, Alamgir Karim, Dharmaraj Raghavan
The kinetics of single stranded-DNA dispersed single wall carbon nanotubes (SWCNTs) adsorption onto an immobilized collagen layer in a microfluidic channel was probed using surface plasmon resonance (SPR) imaging. The adsorption was measured for a range of

Reliability Issues of SiC MOSFETs: A Technology for High Temperature Environments

September 20, 2010
Author(s)
Liangchun (. Yu, Greg Dunne, Kevin Matocha, Kin P. Cheung, John S. Suehle, Kuang Sheng
The wide-bandgap nature of silicon carbide (SiC) makes it an excellent candidate for applications where high temperature is required. The MOS-controlled power devices are the most favorable structure, however, it is widely believed that silicon oxide on

Advances in Modeling of Scanning Charged-Particle-Microscopy Images

September 19, 2010
Author(s)
Petr Cizmar, Andras Vladar, Michael T. Postek
Modeling scanning electron microscope (SEM) and scanning ion microscope images has recently become necessary, because of its ability to provide repeatable images with a priori determined parameters. Modeled artificial images have been used in evaluation of

Predicting Microstructure Development During Casting of Drug Eluting Coatings

September 19, 2010
Author(s)
David M. Saylor, Jonathan E. Guyer, Daniel Wheeler, James A. Warren
We have devised a novel diffuse interface formulation to model the development of chem- ical and physical inhomogeneities, i.e. microstructure, during the process of casting drug eluting coatings. These inhomogeneities, which depend on the coating

Current induced torques in the presence of spin-orbit coupling

September 17, 2010
Author(s)
Paul M. Haney, Mark D. Stiles
In systems with strong spin-orbit coupling, the relationship between spin-transfer torque and the divergence of the spin current is generalized to a relation between spin transfer torques, total angular momentum current, and mechanical torques. In

The Cooper Pair Transistor

September 17, 2010
Author(s)
Jose A. Aumentado
The Cooper pair transistor (CPT) is a superconducting electrometer that has applications in quantum information as well as fundamental superconductivity studies. Since it operates in a near-dissipationless mode, it has potential as a minimally invasive

A Statistical Test Suite for Random and Pseudorandom Number Generators for Cryptographic Applications

September 16, 2010
Author(s)
Lawrence E. Bassham, Andrew L. Rukhin, Juan Soto, James R. Nechvatal, Miles E. Smid, Stefan D. Leigh, M Levenson, M Vangel, Nathanael A. Heckert, D L. Banks
This paper discusses some aspects of selecting and testing random and pseudorandom number generators. The outputs of such generators may be used in many cryptographic applications, such as the generation of key material. Generators suitable for use in

Photoresist latent and developer images as probed by neutron reflectivity methods

September 16, 2010
Author(s)
Vivek M. Prabhu, Shuhui Kang, David L. VanderHart, Eric K. Lin, Wen-Li Wu
Photoresist materials enable the fabrication of advanced integrated circuits with ever decreasing feature sizes. As next-generation light sources are developed, using extreme ultraviolet light of wavelength 13.5 nm, these highly-tuned formulations must

Stability and Surface Topography Evolution in Nanoimprinted Polymer Patterns under a Thermal Gradient

September 16, 2010
Author(s)
Christopher Soles, Yifu Ding, H. Jerry Qi, Kyle J. Alvine, Hyun W. Ro, Dae Up Ahn, Jack Douglas, Sheng Lin-Gibson
Nanostructures created in polymer films by nanoimprint lithography are subject to large stresses, both those from the imprinting processes as well as stresses arising from the intrinsic thermodynamic instabilities. These stresses can induce nanostructure
