Elastic constants and dimensions of imprinted polymeric nanolines determined from Brillouin light scattering

January 18, 2010
Author(s)
Ward L. Johnson, Sudook A. Kim, Roy H. Geiss, Colm Flannery, Paul R. Heyliger, Christopher L. Soles, Wen-Li Wu, Chengqing C. Wang, Christopher M. Stafford, B D. Vogt
Elastic constants and cross-sectional dimensions of imprinted nanolines of poly(methyl methacrylate) (PMMA) on silicon are determined nondestructively from finite-element inversion analysis of dispersion curves of hypersonic acoustic modes of these

Comparison of Mercury Burdens in Chronically Debilitated and Healthy Loggerhead Sea Turtles (Caretta caretta)

January 15, 2010
Author(s)
Russell D. Day, Jennifer M. Lynch, Craig A. Harms, Al L. Segars, Wendy M. Cluse, Matthew H. Godfrey, A. M. Lee, Margie Peden-Adams, Kelly Thorvalson, Mark Dodd, Terry Norton
An increase in the incidence of debilitated loggerhead sea turtle strandings in the southeastern U.S. has been observed in recent years. These turtles are characterized by emaciation and heavy burdens of external and internal parasites and bacterial

Graphical description of Pauli measurements on stabilizer states

January 15, 2010
Author(s)
Matthew B. Elliott, Bryan K. Eastin, Carlton M. Caves
We use a graphical representation of stabilizer states to describe, simply and efficiently, the effect of measurements of Pauli products on stabilizer states. This work complements our earlier work [Phys. Rev. A 77, 042307 (2008)], which described in

Microsensors in Dynamic Backgrounds: Toward Real-Time Breath Monitoring

January 15, 2010
Author(s)
Kurt D. Benkstein, Baranidharan Raman, Christopher B. Montgomery, C Martinez, Stephen Semancik
We evaluated MEMS microsensor array with chemi-resistive elements for use as a non-invasive clinical diagnostic tool to detect the presence or absence of trace amounts of disease biomarkers in simulated breath samples. The microsensor environment was

DYNAMIC PERCEPTION WORKSHOP REPORT: Requirements and Standards for Advanced Manufacturing

January 14, 2010
Author(s)
Tsai Hong Hong, Elena R. Messina, Hui-Min Huang, Michael O. Shneier, Roger D. Eastman, Jane Shi, James Wells
The Dynamic Perception workshop was intended to further the development of standardized, reproducible, and portable test methods that can advance the technology of sensors and perception systems for new, flexible robotic and automation applications in

Erratum: Parametric interatomic potential for graphene

January 13, 2010
Author(s)
Vinod K. Tewary
This paper is an erratum that corrects some typographical errors in our earlier paper "Parametric interatomic potential for graphene" by V.K. Tewary and B. Yang, published in Physical Review B 79, 075442 (2009).

Complex Systems Program Activities Summary, Fiscal Years 2007-2008

January 12, 2010
Author(s)
Sanford P. Ressler
This report summarizes the work of the Complex Systems Program within NIST s Information Technology Laboratory. The Overview presents some background material and a high-level overview of the Program s activities including significant technical

High-Order Coherences of Chaotic and Coherent Optical States

January 12, 2010
Author(s)
Martin J. Stevens, Burm Baek, Eric Dauler, Andrew J. Kerman, Richard J. Molnar, Scott A. Hamilton, Karl Berggren, Richard P. Mirin, Sae Woo Nam
We demonstrate a new approach to measuring high-order temporal coherences that uses a four-element superconducting nanowire single-photon detector. The four independent, interleaved single-photonsensitive elements parse a single spatial mode of an optical

Overview of the TREC 2008 Blog Track

January 12, 2010
Author(s)
Ian M. Soboroff, Iadh Ounis, Craig Macdonald
The Blog track explores the information seeking behaviour in the blogosphere. The track was introduced in 2006 [1], with a main pilot search task, namely the opinion-finding task. In TREC 2007 [2], the track investigated two main tasks inspired by the

An editorial on the growing importance of soft errors in software.

Polarized Optical Scattering Signatures from Biological Materials

January 11, 2010
Author(s)
W. E. Martin, E. Hesse, J. H. Hough, William Sparks, C. S. Cockell, Z. Ulanowski, Thomas Germer, B. Kaye
The polarization of laser light backscattered from biological samples has been measured over the wavelength range 350 to 850nm. Incident circular, linearly polarized, and unpolarized light produces significant spectrally prominent scattered polarizations

Symmetry and Fourier analysis of the ab-initio-determined torsional variation of structural and Hessian-related quantities for application to vibration-torsion-rotation interactions in CH3OH

January 11, 2010
Author(s)
Li-Hong Xu, Jon T. Hougen, Jonathan M. Fisher, Ronald M. Lees
The aim of the present paper is to investigate the use of quantum chemistry calculations to obtain the torsional dependence of various structural and vibrational-force-field-related quantities that could help in estimating the vibration-torsion-rotation

Vibration spectrum of a low-vibration pulse-tube cryostat from 1 Hz to 20 kHz

January 11, 2010
Author(s)
Akobuije D. Chijioke, John R. Lawall
The vibrations of the cold finger of a low-vibration helium pulse-tube cryostat are measured from 1 Hz to 20 kHz using an optical interferometer specially designed to measure small vibrations at high frequencies in the presence of large vibrations at lower
