Nanoslinky: DNA Entropophoresis Down a Nanofluidic Staircase

October 4, 2010
Author(s)
Elizabeth A. Strychalski, Laurie E. Locascio, Samuel M. Stavis, Michael Gaitan
Almost all nanofluidic devices for biopolymer analysis have been limited by one or two confining structural dimen-sions or the application of external forces for biopolymer manipulation, which has restricted the scope of related lab-on-a-chip technology

NIST WMD update presentation for NISA October, 2010

October 4, 2010
Author(s)
John W. Barton
The presentation will cover recent and upcoming events, changes, and the focus for the NIST Weights and Measures Division (WMD). Topics will include the agency-wide restructuring of NIST, current projects underway at WMD, NIST Handbook 44 changes for 2011

On Multiple-Method Studies

October 4, 2010
Author(s)
Chih-Ming Wang, Hariharan K. Iyer
In this paper we review statistical models that describe measurements from a multiple-method study such as in the development of a reference material. We also review requirements for the so-called GUM compliance as this appears to be an important criterion

On the privacy threats of electronic poll books

October 4, 2010
Author(s)
Stefan Popoveniuc, John M. Kelsey
Electronic poll books make the process of verifying that a voter is authorized to vote and issuing her a ballot faster and more convenient. However, they also introduce a privacy risk: if both the electronic poll book and voting machine or optical scanner

Chromatographic Methods for the Quantification of Free and Chelated Gadolinium Species in MRI Contrast Agent Formulations

October 3, 2010
Author(s)
Danielle Cleveland, Stephen E. Long, Lane C. Sander, William C. Davis, Karen E. Murphy, Catherine A. Rimmer, Lorena Francini, Anil K. Patri
Speciation measurements of gadolinium in liposomal MRI contrast agents are complicated by the presence of emulsifiers, surfactants, and therapeutic agents in the formulations. The present paper describes two robust, hyphenated chromatography methods for

Infrared Spectra of Small Molecular Ions Trapped in Solid Neon

October 3, 2010
Author(s)
Marilyn E. Jacox
The infrared spectrum of a molecular ion provides a unique signature for that species, gives information on its structure, and is amenable to remote sensing. It also serves as a comparison standard for refining ab initio calculations. Experiments in this

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
