Reduced-Scale Test to Assess the Effect of Fire Barriers on the Flaming Combustion of Cored Composites: an Upholstery-Material Case Study

September 4, 2020
Author(s)
Mauro Zammarano, John R. Shields, Isaac T. Leventon, Ickchan Kim, Shonali Nazare, Andre L. Thompson, Rick D. Davis, Artur A. Chernovsky, Matthew F. Bundy
In this work, we describe a reduced-scale test (“Cube” test), based on cone calorimetry, measuring the fire performance (heat release rate, propensity to pool-fire formation, etc.) of composite specimens including a fire barrier (FB) and a flammable core

An accurate and rapid single step protocol for enumeration of cytokine positive T lymphocytes

September 3, 2020
Author(s)
Deepa Rajagopal, Linhua Tian, Shiqiu Xiong, Lili Wang, Jonathan Campbell, Luisa Saraiva, S Vessillier
Activation of T lymphocytes leads to differentiation, characterized by the ability to induce production of cytokines. Accurate determination of cellular subsets that secrete particular cytokine(s) is therefore, a significant parameter for functional

Evaluating Unicast and MBSFN in Public Safety Networks

September 3, 2020
Author(s)
Chunmei Liu, Chen Shen, Jack Chuang, Richard A. Rouil, Hyeong-Ah Choi
Public safety incidents typically involve a significant amount of group traffic and have a stringent requirement of connection reliability. Hence multicast could potentially improve network and user performance significantly, which triggered our study on

Reducing the Measurement Time of Exact NOEs by Non-Uniform Sampling

September 3, 2020
Author(s)
Parker J. Nichols, Alexandra Born, Morkos A. Henen, Dean Strotz, David N. Jones, Frank Delaglio, Beat Vogeli
We have previously reported on the measurement of exact NOEs (eNOEs), which yield a wealth of additional information in comparison to conventional NOEs. We have used these eNOEs in a variety of applications, including calculating high-resolution structures

Design and Engineering Colloidal Magnetic Particles for Nanoscale Thermometry

September 2, 2020
Author(s)
Adam J. Biacchi, Thinh Q. Bui, Cindi L. Dennis, Solomon I. Woods, Angela R. Hight Walker
Thermometry based on magnetic nanoparticles (MNPs) is an emerging technology that allows for remote temperature measurements throughout a volume that are impossible to achieve using conventional probe-based or optical methods. This metrology is based on

Measurement of the 2P1/2-2P3/2 fine structure splitting in fluorine-like Kr, W, Re, Os and Ir

September 2, 2020
Author(s)
Galen O'Neil, Samuel C. Sanders, Paul Szypryt, Dipti Goyal, Amy Gall, Yang Yang, Samuel M. Brewer, W.Bertrand (Randy) Doriese, Joseph Fowler, Daniel Swetz, Joseph N. Tan, Joel Ullom, Andrey V. Volotka, Endre Takacs, Yuri Ralchenko
Quantum electrodynamics (QED) is currently considered to be one of the most accurate theories of fundamental interactions. As its extraordinary precision offers unique scientific opportunities, e.g., search for new physics, stringent experimental tests of

Modeling Temperature Effects on a Coriolis Mass Flowmeter

September 2, 2020
Author(s)
Fabio O. Costa, Jodie Gail Pope, Keith A. Gillis
Coriolis mass flowmeters are known to be stable, have low uncertainty (± 0.1 %), and are insensitive to fluid properties. This meter type is used for many applications, including as transfer standards for proficiency testing and liquified natural gas (LNG)

Users Guide to the HVACSIM+ Configuration Tool

September 2, 2020
Author(s)
Michael A. Galler
HVACSIM+ (HVAC SIMulation PLUS other systems) was introduced by the National Institute of Standards and Technology (NIST) in 1985 as a computer simulation tool to simulate building systems. The HVACSIM+ computer program package and manuals have been

A NEIGHBORHOOD-BASED NEURAL NETWORK FOR MELT POOL PREDICTION AND CONTROL

September 1, 2020
Author(s)
Paul Witherell, Vadim Shapiro, Yaqi Zhang
One of the most prevalent additive manufacturing processes, the powder bed fusion process, is driven by a moving heat source that melts metals to build a part. This moving heat source, and the subsequent formation and moving of a melt pool, plays an
