Assessment of Factors Affecting Fire Performance of Mattresses: A Review

September 3, 2012
Author(s)
Rick D. Davis, Shonali Nazare, Kathryn M. Butler
An in-depth analysis of U.S. residential fire statistics shows that although the total number of fires and deaths due to mattress fires has dropped as a result of several regulatory approaches, the mattress/bedding fires continue to account for one of the

Data Quality for High Content Screening

September 3, 2012
Author(s)
YaShian Li-Baboud, Oleg Aulov, Peter Bajcsy
TO HAVE CONFIDENCE IN THE KNOWLEDGE GLEANED FROM DATA, IT IS ESSENTIAL TO VERIFY THE QUALITY OF THE DATA SOURCES AND TO HAVE A MEANS OF QUANTIFYING THE POTENTIAL UNCERTAINTIES DUE TO THE QUALITY OF DATA FOR MAKING CRITICAL, INTELLIGENT DECISIONS. HIGH

Evaluation of viability and proliferation profiles on macrophages treated with silica nanoparticles in vitro via plate-based, flow cytometry, and Coulter counter assays

September 3, 2012
Author(s)
Simona Bancos, De-Hao D. Tsai, Vincent A. Hackley, J L. Weaver, Katherine M. Tyner
Nanoparticles (NPs) are known to interfere with many high throughput cell viability and cell proliferation assays, which complicates the assessment of their potential toxic effects. The aim of this study was to compare viability and proliferation results

Author(s)
Regina R. Montgomery
The SRM Spotlight is a newsletter published by the Measurement Services Division for users of NIST standard reference materials. The Spotlight announces new reference materials and provides information about their use. In addition, this newsletter contains

A New Limit on Time-Reversal Violation in Beta Decay

September 2, 2012
Author(s)
Hans P. Mumm, T E. Chupp, K P. Coulter, R L. Cooper, S J. Freedman, B. K. Fujikawa, A. Garcia, Gordon L. Jones, Jeffrey S. Nico, Alan K. Thompson, C A. Trull, J. F. Wilkerson, F. E. Wiefeldt
We report the results of an improved determination of the triple correlation DP • (p_e × p_v) that can be used to limit possible time-reversal invariance in the beta decay of polarized neutrons and constrain extensions to the Standard Model. Our result is

Signal Processing Techniques for Smart Grid: Scanning the Issue

September 2, 2012
Author(s)
Hamid Gharavi
This is an editorial article for a special issue on Smart Grid. The main emphasis of this issue is the technical challenges of the Smart Grid from a signal processing perspective. Therefore, the selected articles aim at articulating signal processing

A Sub-Sampling Digital PM/AM Noise Measurement System

September 1, 2012
Author(s)
Craig W. Nelson, David A. Howe
A digital phase/amplitude modulation (PM/AM) noise measurement systems (DNMS) implementing field progammable gate array (FPGA) based digital down converters (DDCs), and 250 MHz analog to digital converters (ADCs) is reported. Measurements in the first

Disentangling the effects of polymer coatings on silver nanoparticle agglomeration, dissolution, and toxicity to determine mechanisms of nanotoxicity

September 1, 2012
Author(s)
Justin M. Zook, Melissa D. Halter, Danielle Cleveland, Stephen E. Long
Silver nanoparticles (AgNPs) are frequently coated by a variety of polymers, which may affect various intertwined mechanisms of toxicity, including agglomeration and dissolution rate. Here, we measure how citrate, dextran, poly(ethylene glycol) (PEG)

Evaluation of Low-Ohmic Resistance Measurement Capabilities Between VSL and NIST

September 1, 2012
Author(s)
Marlin E. Kraft, Jan van der Beek, Gert Rietveld
The low-ohmic resistance measurement capa¬bilities of VSL and NIST were compared using a set of resistors with values 100 mOhm, 10 mOhm, 1 mOhm, and 100 mOhm respectively. The measurement data of both laboratories generally agree well within the combined

Expression and characterization of 15N-labeled human C-reactive protein in Escherichia coli and Pichia pastoris for use in isotope-dilution mass spectrometry

September 1, 2012
Author(s)
Eric L. Kilpatrick, Wei-Li Liao, Johanna Camara, Illarion V. Turko, David M. Bunk
Isotope dilution mass spectrometry using stable isotope labeled internal standards is unsurpassed in its ability to quantify analytes with accuracy and low measurement uncertainty. The extension of this technique to proteins relies upon the expression of

Author(s)
Therese P. McAllister, Fahim Sadek, John L. Gross, Jason D. Averill, Richard G. Gann
This paper summarizes the primary structural systems which comprised World Trade Center 1, World Trade Center 2, and World Trade Center 7. The buildings were destroyed in the terrorist attacks of September 11, 2001. This paper describes the four major

UV-Assisted Alcohol Sensing Using SnO_(2) Functionalized GaN Nanowire Devices

September 1, 2012
Author(s)
Ritu Bajpai, Abhishek Motayed, Albert Davydov, Vladimir Oleshko, Geetha G. Aluri, Kristine A. Bertness, Mulpuri V. Rao, Mona E. Zaghloul
A chemiresistor type sensor for selective alcohol sensing has been realized from gallium nitride nanowires (NWs) functionalized with sputter-deposited tin dioxide nanoparticles. Two-terminal devices were fabricated using standard microfabrication
