Extended Feature Set Profile Specification

January 14, 2013
Author(s)
Melissa Taylor, Will Chapman, Austin Hicklin, George Kiebuzinski, John Mayer-Splain, Rachel Wallner, Peter Komarinski
This specification defines Extended Feature Set (EFS) Profiles - sets of features to be used in latent friction ridge (fingerprint, palmprint or plantar) searches of automated friction ridge identification systems (AFIS). The EFS Profiles are designed to

Measurement of Scattering and Absorption Cross Sections of Dyed Microspheres

January 14, 2013
Author(s)
Adolfas Gaigalas, Steven J. Choquette
Measurements of absorbance and fluorescence emission were carried out on aqueous suspensions of polystyrene (PS) microspheres with a diameter of 2.5 µm. Microspheres with and without green BODIPY@ dye were measured. Placing the suspension inside an

Selective Streptavidin Bioconjugation on Si and SiC nanowires for Biosensor Applications.

January 14, 2013

Elissa H. Williams, John A. Schreifels, Mulpuri V. Rao, Albert Davydov, Vladimir P. Oleshko, Nancy J. Lin, Kristen L. Steffens, Sergiy Krylyuk, Kristine A. Bertness, Amy Manocchi, Yaroslav Koshka
A functionalization method for the specific and selective immobilization of the streptavidin (SA) protein on semiconductor nanowires (NWs) was developed. Silicon (Si) and silicon carbide (SiC) NWs were functionalized with 3-aminopropyltriethoxysilane

Putting a spin on LA-ICPMS analysis combined with isotope dilution

January 11, 2013
Author(s)
John L. Molloy, Stephen E. Long, Fanny Claverie, Julian Malherbe, Naomi Bier
The determination of Zn, Sr, Ba and Pb in solid samples has been achieved by Laser Ablation Inductively Coupled Plasma Isotope Dilution Mass Spectrometry (LA-ICP-IDMS) using a spinning sampling platform. The fast rotation of a sample and an isotopically

Reconstruction of the Thermal Environment in the Tall World Trade Center Buildings

January 11, 2013
Author(s)
Richard G. Gann, Anthony P. Hamins, Kevin B. McGrattan, Thomas J. Ohlemiller, Kuldeep R. Prasad, William M. Pitts, Harold E. Nelson
The National Institute of Standards and Technology (NIST) conducted an extensive investigation of the collapse of the three tall World Trade Center (WTC) buildings. This paper describes the reconstruction of the fires, the thermal environment they created

AGVs and Forklifts Gaining Sight for Safety

January 10, 2013
Author(s)
Roger V. Bostelman
Forklifts and automated guided vehicles are useful tools for the manufacturing industry. With regard to safety of workers (and equipment) near industrial vehicles, there are issues when using either manned or automated powered industrial vehicles in

Driving Phase Slips in a Superfluid Atom Circuit with a Rotating Weak Link

January 10, 2013
Author(s)
Kevin C. Wright, William D. Phillips, Gretchen K. Campbell
We have induced well-defined phase slips between quantized persistent current states around a toroidal atomic 23Na Bose-Einstein condensate by rotating a weak link (a localized region of reduced superfluid density) around the ring at low angular frequency

RF and A/MS Technologies

January 10, 2013
Author(s)
Herbert S. Bennett, John J. Pekarik
Radio frequency (RF), high-frequency (HF) and analog/mixed-signal (A/MS) technologies serve the rapidly growing communications and More than Moore (MtM) markets and represent essential and critical technologies for the success of many semiconductor

Summary of the Workshop on Cryptographic Key Management Systems (CKMS)

January 10, 2013
Author(s)
Elaine B. Barker, Miles Smid, Dennis Branstad
A workshop was held on September 10-11, 2012 to discuss two documents that have been posted for public comment: SP 800-130 (A Framework for Designing Cryptographic Key Management Systems) and a table of proposed requirements for SP 800-152 (A Profile for U

Band Offset Determination of Atomic-Layer-Deposited Al2O3 and HfO2 on InP by Internal Photoemission and Spectroscopic Ellipsometry

January 9, 2013
Author(s)
Kun Xu, Oleg A. Kirillov, David J. Gundlach, Nhan V. Nguyen, Pei D. Ye, Min Xu, Lin Dong, Hong Sio
Band offsets at the interfaces of n- and p-type InP ((100) and (111)A) and atomic-layer-deposited (ALD) Al2O3 were measured with internal photoemission and spectroscopic ellipsometry. Similarly, the band offsets at the interface of semi-insulating InP (100

Simulation and Analysis for Sustainable Product Development

January 9, 2013
Author(s)
Mahesh Mani
Purpose: Simulation plays a critical role in the design of products, materials and manufacturing processes. However, there are gaps in the simulation tools used by industry to provide reliable results from which effective decisions can be made about

The relation between trees and human health: evidence from the spread of the emerald ash borer

January 8, 2013
Author(s)
Geoffrey Donovan, David Butry, Yvonne Michael, Jeffrey P. Prestemon, Andrew Liebhold, Demetrios Gatziolis, Megan Mao
Background: Exposure to the natural environment may improve human health. However, existing research is limited by the use of cross-sectional study designs. Objectives: We made use of a unique natural experiment—the spread of the emerald ash borer, an

Size-Dependent Structural Distortions

January 7, 2013
Author(s)
Michael D. Anderson, Colby L. Heideman, Qiyin Lin, Mary Smeller, Robert S. Kokenyesi, Andrew Herzing, Ian M. Anderson, Douglas A. Keszler, Paul Zschack, David C. Johnson
Recently we reported that intergrowth compounds [(MSe)1+y]m(TSe2)n, with M = Pb, Bi Ce} and T = W, Nb, Ta} self assemble from designed precursors. The values of m and n represent, respectively, the number of MSe and TSe2 structural units of the unit cell
