Simulation of a Medium Frequency Mesh Network for Communications in Underground Mines

October 3, 2010
Author(s)
Michael R. Souryal, Fabien A. Valoit, Hui Guo, Nader Moayeri, Nicholas W. Damiano, David P. Snyder
Signals at the lower end of the medium frequency range (300 kHz to 3000 kHz) propagate with relatively low attenuation along existing metallic infrastructure in an underground mine, such as cables, pipes and rails. Exploiting this capability, low-bandwidth

All-optical Generation of States for "Encoding a Qubit in an Oscillator"

October 1, 2010
Author(s)
Hilma M. Vasconcelos, Liliana Sanz, Scott Glancy
Both discrete and continuous signals are used to carry classical information. Analogously, discrete and continuous systems can be used to encode quantum information. Most quantum computation schemes propose enconding qubits using two level systems, such a

An example crossover experiment for testing new vicarious calibration techniques for satellite ocean color radiometry

October 1, 2010
Author(s)
Kenneth Voss, Scott McLean, Stephanie J. Flora, Michael Feinholz, Mark A. Yarbrough, Charles Trees, Mike Twardowski, Dennis Clark, Marlon Lewis, B. Carol Johnson
Vicarious calibration of ocean color satellites involves accurate surface measurements of water-leaving radiance to update and improve the system calibration of ocean color satellite sensors. An experiment was performed to compare a free-fall technique

Annual Report of the National Earthquake Hazards Reduction Program for Fiscal Year 2009

October 1, 2010
Author(s)
John(Jack) R. Hayes Jr., Edward Laatsch, Joy Pauschke, David Applegate, John Filson
This report about the National Earthquake Hazards Reduction Program (NEHRP) during fiscal year 2009 is submitted to Congress by the Interagency Coordinating Committee (ICC) of NEHRP, as required by the Earthquake Hazards Reduction Program Reauthorization

Atomistic Factors Governing Adhesion between Diamond, Amorphous Carbon, and Model Diamond Nanocomposite Surfaces

October 1, 2010
Author(s)
Pamela L. Piotrowski, Rachel J. Cannara, Guangtu Gao, Joseph J. Urban, Robert W. Carpick, Judith A. Harrison
Complementary atomic force microscopy (AFM) and molecular dynamics (MD) simulations were conducted to determine the work of adhesion for diamond(111)(1x1) and diamond(001)(2x1) surfaces paired with other carbon-based materials. In the AFM experiments, the

Characterization of a Soluble Anthradithiophene Derivative

October 1, 2010
Author(s)
Brad Conrad, Calvin Chan, Marsha A. Loth, Sean R. Parkin, Xinran Zhang, John E. Anthony, David J. Gundlach
The structural and electrical properties of a new solution processable material, 2,8-diflouro-5,11-tert-butyldimethylsilylethynl anthradithiophene (TBDMS), were measured for single crystal and spun cast thin-film transistors. TBDMS is observed to readily

Depletion of Abundant Plasma Proteins and Limitations of Plasma Proteomics

October 1, 2010
Author(s)
Chengjian Tu, Paul A. Rudnick, Misti Y. Martinez, Kristin L. Cheek, Stephen Stein, Robert J. Slebos, Daniel C. Liebler
Immunoaffinity depletion of high abundance plasma proteins is frequently employed to enhance detection of lower abundance proteins in both shotgun and targeted proteomic analyses. Here we present a detailed evaluation of the Agilent Multiple Affinity

Diffusion in Single Solid Supported Lipid Bilayers Studied by Quasi-Elastic Neutron Scattering

October 1, 2010
Author(s)
Clare L. Armstrong, Martin D. Kaye, Michaela Zamponi, E. Mamontov, Madhu Sudan Tyagi, Timothy Jenkins, Maikel C. Rheinstadter
It seems to be increasingly accepted that the diversity and composition of lipids play an important role in the function of biological membranes. A prime example of this are lipid rafts; regions enriched with certain types of lipids which are speculated to

Effect of Phase Change and Solute Diffusion on Spreading on a Dissolving Substrate

October 1, 2010
Author(s)
Walter Villanueva, William J. Boettinger, James A. Warren, Gustav Amberg
Dissolutive wetting is investigated numerically using a diffuse-interface model that incorporates fluid flow, solute diffusion, and phase change. A range of materials parameters are investigated that: 1) permits recovery of the hydrodynamic limit by

Fire Effluent Component Yields from Room-scale Fire Tests

October 1, 2010
Author(s)
Richard G. Gann, Jason D. Averill, Erik L. Johnsson, Marc R. Nyden, Richard D. Peacock
Estimation of the time available for escape (ASET) in the event of a fire is a principal component in fire hazard or risk assessment. Valid data on the yields of toxic smoke components from bench-scale apparatus is essential to accurate ASET calculations

Future SC4 Architecture PWI - Report and Technical Discussion

October 1, 2010
Author(s)
Allison Barnard Feeney
This document is the report of the Future SC4 architecture PWI. It provides information about the draft “Industrial Data Integrated Ontologies and Models (IDIOM) architecture specification” created by the PWI. The work of the Preliminary Work Item (PWI)

Intercomparison of Methods for Detecting and Characterizing Voids in Bonded Wafer Pairs

October 1, 2010
Author(s)
Richard A. Allen, Andrew C. Rudack, David T. Read, Winthrop A. Baylies
The Wafer Bond Task Force of the SEMI MEMS Standards Committee has begun a round robin experiment to evaluate methods for identifying and characterizing voids in bonded wafer pairs for three-dimensional integrated circuit (3D IC) applications. Due to the

Nano- and Atom-scale Length Metrology

October 1, 2010
Author(s)
Theodore V. Vorburger, Ronald G. Dixson, Ndubuisi G. Orji, Joseph Fu, Richard A. Allen, Michael W. Cresswell, Vincent A. Hackley
Measurements of length at the nano-scale have increasing importance in manufacturing, especially in the electronics and biomedical industries. The properties of linewidth and step height are critical to the function and specification of semiconductor
