Fabrication of GaAs/AlOx micropillars for small mode volume

January 20, 2010
Author(s)
Richard P. Mirin
Micropillar devices have shown promise as single photon sources for applications in quantum key distribution as well as single photon metrology and fundamental science. For higher temperature operation (77K), a high quality (Q) factor cavity and a small

Metabolomic Analysis of Atlantic Blue Crab, Callinectes sapidus, Hemolymph Following Oxidative Stress

January 20, 2010
Author(s)
Tracey Johnston, Dan Bearden, Arezue Boroujerdi, David A. Stancyk, Lindy Thibodeaux, Karen G. Burnett, Louis E. Burnett
The Atlantic blue crab, Callinectes sapidus, is an economically, ecologically and recreationally valuable decapod crustacean that inhabits estuaries along the Atlantic and Gulf coasts of the United States. In their natural environment, blue crabs are

Phase Diagram of Magnetic Nanodisks measured by SEMPA

January 20, 2010
Author(s)
Seok-Hwan Chung, Robert D. McMichael, Daniel T. Pierce, John Unguris
We use Scanning Electron Microscopy with Polarization Analysis (SEMPA) to image the magnetic domain structures of individual ferromagnetic nanodisks with different diameters and thicknesses, and thereby determine the phase diagram of the magnetic ground

The Semantics of Modules in Common Logic

January 20, 2010
Author(s)
Fabian M. Neuhaus
Common Logic (CL) is an ISO standard that specifies a family of knowledge representation languages. The function of modules within CL is to support local context with a local domains of discourse. Modules play a crucial role since they enable users to

Solvent Retention In Thin Spin-Coated Polystyrene And Poly(Methyl Methacrylate) Homopolymer Films Studied By Neutron Reflectometry

January 19, 2010
Author(s)
Xiaohua Zhang, Kevin G. Yager, Shuhui Kang, Nathaniel J. Fredin, Bulent Akgun, Sushil K. Satija, Jack F. Douglas, Alamgir Karim, Ronald L. Jones
We utilize neutron reflectometry (NR) to probe the amount of residual solvent inside thin polystyrene (PS) and poly(methyl methacrylate) (PMMA) films spin-coated from deuterated toluene polymer solutions onto silicon substrates . The effect of thermal

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
