Probing Pluripotency Gene Regulatory Networks with Live Cell Imaging

September 20, 2020
Author(s)
Anne Plant, Michael Halter, Jeffrey R. Stinson
Live cell imaging uniquely enables the measurement of dynamic events in single cells, but it has not been used often in the study of gene regulatory networks. Network components can be examined in relation to one another by quantitative live cell imaging

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

Measuring Microfluidic Flow Rates: Monotonicity, Convexity and Uncertainty

August 20, 2020
Author(s)
Paul Patrone, Qing Hai Li, Gregory A. Cooksey, Anthony J. Kearsley
A class of non-linear integro-differential equations characterizing microfluidic measurements is considered. Under reasonable conditions, these non-linear integro-differential equations admit solutions that are convex functions of an interesting flow-rate

Role of Uncertainty in the Durability of Composite Material Systems

August 17, 2020
Author(s)
Jeffrey T. Fong, Nathanael A. Heckert, James J. Filliben
This paper is a chapter invited by the editor of a book to be published by Elsevier in 2020. The title of the book is "Durability of Composite Systems," and the editor is Prof. Kenneth Reifsnider, N.A.E., University of Texas at Arlington, Arlington, TX, U

CONTAM User Guide and Program Documentation Version 3.4

August 3, 2020
Author(s)
William Stuart Dols, Brian Polidoro
This manual describes the computer program CONTAM version 3.4, developed by NIST. CONTAM is a multizone indoor air quality and ventilation analysis program designed to help determine airflows, contaminant concentrations, and occupant exposure in buildings

Data-driven characterization of computational models for powder-bed-fusion additive manufacturing

July 31, 2020
Author(s)
Yan Lu, Zhuo Yang, Paul W. Witherell, Wentao Yan, Kevontrez Jones, Gregory Wagner, Wing-Kam Liu, Jason C. Fox
Computational modeling for additive manufacturing has proven to be a powerful tool to understand the physical mechanisms, predict fabrication quality, and guide design and optimization. Varieties of models have been developed with different assumptions and
