Propane Gas Fire Experiments in Residential Scale Structures

February 27, 2017
Author(s)
Joseph M. Willi
Nine full-scale fire experiments were conducted in two residential-scale structures to study how different fire fighting tactics, specifically horizontal, vertical, and positive pressure ventilation, affect the fire environment within a structure. The fire

Characterization of a PXIe based low-field digital NMR spectrometer

February 25, 2017
Author(s)
Joshua R. Biller, Karl F. Stupic, Anthony B. Kos, Timothy Weilert, George Rinard, Yoshi Nakashima, John M. Moreland
A low-field nuclear magnetic resonance (NMR) instrument is an important tool for investigating a wide variety of samples under different conditions. In this paper, we describe a system constructed primarily with commercially available hardware and control

Review of the 9th NLTE code comparison workshop

Author(s)
R. Piron, F. Gilleron, Y Aglitskiy, H.-K. Chung, C. J. Fontes, S. B. Hansen, O. Marchuk, H. Scott, E. Stambulchik, Yuri Ralchenko
We review the 9th NLTE code comparison workshop, which was held in the Jussieu campus, Paris, from November 30th to December 4th, 2015. This time, the workshop was mainly focused on a systematic investigation of iron NLTE steady-state kinetics and

The Cu II Spectrum

February 24, 2017
Author(s)
Alexander Kramida, Gillian Nave, Joseph Reader
New wavelength measurements in the vacuum ultraviolet (VUV), ultraviolet and visible spectral regions have been combined with available literature data to refine and extend the description of the spectrum of singly ionized copper (Cu II). In the VUV region

Classification of petroleum Standard Reference Materials and other fuels by chemometric analysis of gas chromatography-mass spectrometry data

February 23, 2017
Author(s)
Werickson Fortunato de Carvalho Rocha, Michele M. Schantz, David Sheen, Katrice Lippa, Pamela M. Chu
As feedstocks transition from conventional oil to increasing amounts of unconventional petroleum sources and biomass, it will be necessary to determine whether a particular fuel or fuel blend is suitable for use in engines. Certifying a fuel as safe for

Dynamical Heterogeneity in a Vapor-Deposited Polymer Glass

February 23, 2017
Author(s)
Jack F. Douglas, Wengang Zhang, Francis W. Starr
Recently, there has been great interest in 'ultrastable' glasses formed via vapor deposition, both because of emerging applications of these materials (e.g., active layers in light-emitting diodes and photovoltaics) and, theoretically, as materials for

Building Caring Healthcare Systems in the Internet of Things

February 22, 2017
Author(s)
Phillip Laplante, Mohamad Kassab, Nancy Laplante, Jeff Voas
The nature of healthcare and the computational and physical technologies and constraints present a number of challenges to systems designers and implementers. In spite of the challenges, there is a significant market for systems and products to support

Comparison between angularly and spectrally resolved gloss measurements with gloss measurements carried out on a national reference goniometer for gloss calibration

February 22, 2017
Author(s)
Andree R. Charriere, Maria E. Nadal, Clarence Zarobila
The present work consists in developing a procedure which will allow to compare gloss values obtained from an angularly and spectrally resolved Bidirectional Reflectance Distribution Function (BRDF) measurement and gloss values measured with a national

Entropy-Driven Segregation of Polymer-Grafted Nanoparticles under Confinement

February 22, 2017
Author(s)
Ren Zhang, Bongjoon Lee, Christopher Stafford, J. F. Douglas, Andrey V. Dobrynin, Michael R. Bockstaller, Alamgir Karim
Polymer-grafted nanoparticles (PGNPs) have attracted much attention due to the enhanced dispersion in polymeric materials via an interacting brush layer that enables unique functionality and stability. The miscibility and organization of nanoparticles

Advanced Waveform Synthesis with Pulse-driven Josephson Voltage Standards

February 21, 2017
Author(s)
Justus A. Brevik, Nathan E. Flowers-Jacobs, Anna E. Fox, Evan B. Golden, Paul D. Dresselhaus, Samuel P. Benz
We describe the implementation of new commercial pulse-bias electronics that have enabled an improvement in the generation of quantum-accurate waveforms both with and without low-frequency compensation biases. We have used these electronics to apply a

Guide for Cybersecurity Incident Recovery

February 21, 2017
Author(s)
Murugiah P. Souppaya, Larry Feldman, Gregory A. Witte
This bulletin summarizes the information presented in NIST SP 800-184: Guide for Cybersecurity Event Recovery. The publication provides organizations with strategic guidance for planning, playbook developing, testing and improvements of recovery planning

Hybrid quantum systems with trapped charged particles

February 21, 2017
Author(s)
Shlomi S. Kotler, Raymond Simmonds, Dietrich Leibfried, David J. Wineland
Trapped charged particles have been at the forefront of quantum information processing (QIP) for a few decades now, with deterministic two-qubit logic gates reaching record fidelities of 99.9% and single-qubit operations of much higher fidelity. In a

In situ X-ray scattering studies of the influence of an additive on the formation of a low-bandgap bulk- heterojunction

February 21, 2017

Jeffrey W. Sowards, Erik A. Pfeif, Matthew J. Connolly, Joseph D. McColskey, Stephanie L. Miller, Brian J. Simonds, James R. Fekete
Incorporation of high-strength steels into ground vehicles provides a weight-savings advantage by using thinner sections of material, which increases vehicle efficiency. Advanced welding techniques such as fiber laser welding are a potential method for

Measurements of translation initiation from all 64 codons in E. coli

Ariel H. Hecht, Jeff E. Glasgow, Paul Jaschke, Lukmaan Bawazer, Matthew S. Munson, Jennifer R. Cochran, Drew Endy, Marc L. Salit
Our understanding of translation represents a cornerstone of molecular biology and underpins our capacity to engineer living matter. For decades, the codon AUG and a few near-cognates (GUG, UUG) have been exclusively considered as “start codons” for
