Spin-Wave Propagation in the Presence of Interfacial Dzyaloshinskii-Moriya Interaction

November 4, 2013
Author(s)
Jung-Hwan Moon, Soo-Man Seo, Kyung Jin Lee, Kyoung-Whan Kim, Jisu Ryu, Hyun-Woo Lee, Robert McMichael, Mark D. Stiles
In ferromagnetic thin films, broken inversion symmetry and spin-orbit coupling give rise to interfacial Dzyaloshinskii-Moriya interactions. Analytic expressions for spin-wave properties show that the Dzyaloshinskii-Moriya interaction leads to non

Unaware Person Recognition from the Body when Face Identification Fails

November 4, 2013
Author(s)
P J. Phillips, Rice Allyson, Vaidehi Natu, Xiabo An, Alice O'Toole
How do we recognize someone when the face fails? We show that people rely on the body, but are unaware of this. State-of-the-art face recognition algorithms were used to select images of people with no useful identity information in the face. Human

What's in a Name

November 4, 2013
Author(s)
Ursula R. Kattner
In the early days of alloy phase diagrams phases were named using Greek letters in unary systems, from lower temperatures to higher temperatures, and in binary systems from the left to the right hand side of the system. This convenient convention allows

High Resolution Frequency Comb Molecular Spectroscopy.

November 3, 2013
Author(s)
Ian R. Coddington, Alexander M. Zolot, Esther Baumann, Fabrizio R. Giorgetta, Greg B. Rieker, Jeffrey W. Nicholson, William C. Swann, Nathan R. Newbury
Frequency combs serve as an extremely high accuracy reference across broad portions of the optical spectrum. Dual frequency combs harness this accuracy and allow for fast and highly fidelity molecular spectroscopy.

Methods for Optimizing and Extending the Performance of Chemiresistive Gas Microsensors

November 3, 2013
Author(s)
Kurt D. Benkstein, Alexander (. Vergara Tinoco, Christopher B. Montgomery, Baranidharan Raman, Stephen Semancik
This paper briefly describes varied concepts developed and implemented to enhance the performance of gas-phase chemical microsensors. The developments are illustrated for chemiresistive (MEMS) microdevices, and involve efficient, array-based approaches to

A Framework to Update the Plan to Coordinate NEHRP Post-Earthquake Investigations

November 1, 2013
Author(s)
William Holmes, Jonathan Bray, Thomas Holzer, Laurie Johnson, Jack Moehle, Sharon Wood
In 2007, the National Institute of Standards and Technology (NIST) awarded a National Earthquake Hazards Reduction Program (NEHRP) "Earthquake Structural and Engineering Research" contract (SB1341-07-CQ-0019) to the NEHRP Consultants Joint Venture, a

Airbrushed Nanofiber Scaffolds Support Bone Marrow Stromal Cell Differentiation

November 1, 2013
Author(s)
Carl G. Simon Jr., Wojtek J. Tutak, Sumona Sarkar, Tanya M. Farooque, Jyotsnendu J. Giri, Dongbo Wang, Sheng Lin-Gibson, Joachim Kohn, Durgadas Bolikal
Nanofiber scaffolds are effective for tissue engineering since they emulate the fibrous nanostructure of native extracellular matrix (ECM). Although electrospinning has been the most common approach for fabricating nanofiber scaffolds, airbrushing

Analysis of Contact Interfaces for Single GaN Nanowire Devices

November 1, 2013
Author(s)
Andrew M. Herrero, Paul T. Blanchard, Kristine A. Bertness
Single GaN nanowire (NW) devices fabricated on SiO 2 can exhibit a strong degradation after annealing due to the occurrence of void formation at the contact/SiO 2 interface. This void formation can cause cracking and delamination of the metal film, which

Checking the Net Content of Packaged Goods (NIST HB 133-2014)

November 1, 2013
Author(s)
Linda D. Crown, David A. Sefcik, Lisa Warfield
This handbook has been prepared as a procedural guide for the compliance testing of net contents statements on packaged goods. Compliance testing of packaged goods is the determination of the conformance results of the packaging, distribution, and

Delay Behavior of On-Off Scheduling: Extending Idle Periods

November 1, 2013
Author(s)
Allen L. Roginsky, Ken Christensen, Mehrgan Mostowfi
On-off scheduling of systems that have the ability to sleep can be used to extend system idle periods and enable greater opportunities for energy savings from sleeping. In this paper, we achieve a theoretical understanding of the delay behavior of on-off

Does Your SEM Really Tell the Truth? Part 2

November 1, 2013
Author(s)
Michael T. Postek, Andras Vladar, Premsagar P. Kavuri
The scanning electron microscope (SEM) has gone through a tremendous evolution to become indispensable for many and diverse scientific and industrial applications. The first paper in this series, discussed some of the issues related to signal generation in

High-resolution K-shell spectra from laser excited molybdenum plasma

November 1, 2013
Author(s)
Lawrence T. Hudson, C.I Szabo, P Indelicatio, John F. Seely, T Ma
X-ray spectra from Molybdenum plasmas were recorded by a Cauchois-type cylindrically bent Transmission Crystal Spectrometer (TCS). The absolutely calibrated spectrometer provides an unprecedented resolution of inner shell transitions (K x-ray radiation)
