SI Measurement System Chart

August 24, 2017
Author(s)
Elizabeth J. Benham
This publication is a colorful chart explaining the 7 base units of the SI (International System of Units) and prefix symbols, featuring the Measurement League: Guardians of the SI. The Measurement League are superheroes dedicated to the fight against

Broadband, high-resolution investigation of advanced absorption lineshapes at high temperature

August 23, 2017
Author(s)
Ian R. Coddington, William C. Swann, Nathan R. Newbury, Paul J. Schroeder, Matthew J. Cich, Jinyu Yang, Brian J. Drouin, Gregory B. Rieker
Spectroscopic studies of planetary atmospheres and high-temperature processes (e.g. combustion) require absorption lineshape models that are accurate over extended temperature ranges. To date, advanced lineshapes, like the speed-dependent Voigt and Rautian

Formation of the Ni3Nb delta-phase in stress-relieved Inconel 625 produced via powder-bed laser fusion additive manufacturing

August 23, 2017
Author(s)
Eric Lass, Mark R. Stoudt, Maureen E. Williams, Michael B. Katz, Thien Q. Phan, Lyle E. Levine, Thomas H. Gnaeupel-Herold
The microstructural evolution of laser powder-bed additively manufactured Inconel 625 during a post-build stress-relief anneal of 1 h at 870 °C is investigated. It is found that this industry-recommended heat treatment promotes the formation of a

MediFor Nimble Challenge Evaluation 2017

August 23, 2017
Author(s)
Jonathan G. Fiscus, Haiying Guan, Yooyoung Lee, Amy Yates, Andrew Delgado, Daniel F. Zhou, David M. Joy, August L. Pereira
NIST presentation slides for DARPA MediFor Program One-Year PI Meeting

Lipid Nanodomains Change Ion Channel Function

August 22, 2017
Author(s)
Michael NMN Weinrich, David Worcester, Sergey M. Bezrukov
Signaling proteins and neurotransmitter receptors associate with cholesterol-rich fractions of cell membranes--lipid rafts. The different lipid environment in rafts can modulate protein function, but evidence for modulation of ion channels is lacking. Here

Modelling and Influencing Human Behaviour in Fire

August 22, 2017
Author(s)
Steve Gwynne, Erica D. Kuligowski, Michael Kinsey, Lynn Hulse
The purpose of this article is to present a conceptual model of human behaviour in fire and its impact on evacuation modelling, life safety analyses, and evacuation procedures. This model is based on a theoretical framework of individual decision-making

Quantitative Scanning Probe Microscopy for Nanomechanical Forensics

August 22, 2017
Author(s)
Frank W. DelRio, Robert F. Cook
Scanning probe microscopy techniques—in particular atomic force microscopy (AFM)—provide a means for imaging objects and measuring mechanical properties at the nano- and micro-scales in a non-destructive manner. In this paper, the previous use of AFM in

A serum small molecule biosignature of radiation exposure from total body irradiated patients

August 21, 2017
Author(s)
Evagelia C. Laiakis, Evan L. Pannkuk, Siddheshwar Chauthe, Yi-Wen Wang, Ming Liang, Tytus Mak, Christopher A. Barker, Giuseppe Astarita, Albert J. Fornace
The potential of radiological accidents and nuclear terrorism have increased the need for development of new rapid biodosimetry methods. In addition, in a clinical setting the issue of an individual's radiosensitivity should be taken into consideration

Blunt scratch strength of polycrystalline alumina

August 21, 2017
Author(s)
Robert F. Cook
A model for the fracture strength of brittle materials controlled by blunt (spherical) scratches is developed and compared with measurements on a polycrystalline alumina. The model is based on a residual stress-intensity factor for median cracks at

Developing an Assessment Methodology for Community Resilience

August 21, 2017
Author(s)
Maria Dillard
Communities can be characterized as complex systems, with resilience as an emergent property. Complex systems are systems composed of interconnected parts that exhibit emergent properties that arise from the collective and cannot be derived from the

Strain Measurement of 3D Structured Nanodevices by EBSD

August 20, 2017
Author(s)
William A. Osborn, Lawrence H. Friedman, Mark D. Vaudin
We present a new methodology to accurately measure strain magnitudes from 3D nanodevices using Electron Backscatter Diffraction (EBSD). Because the dimensions of features on these devices are smaller than the interaction volume for backscattered electrons

The 2016 NIST Speaker Recognition Evaluation

August 20, 2017
Author(s)
Seyed Omid Sadjadi, Timothee N. Kheyrkhah, Audrey N. Tong, Craig S. Greenberg, Douglas A. Reynolds, Elliot Singer, Lisa Mason, Jaime Hernandez-Cordero
In 2016, NIST conducted the most recent in an ongoing series of speaker recognition evaluations (SRE) to foster research in robust text-independent speaker recognition, as well as measure performance of the current state-of-the-art systems, targeting in

Conceptual Modeling

August 19, 2017
Author(s)
Conrad E. Bock, Fatma Dandashi, Sanford Friedenthal, Natalie Harrison, Steven Jenkins, Leon McGinnis, Janos Sztipanovits, Adelinde Uhrmacher, Eric Weisel, Lin Zhang
Understanding and developing complex systems requires collaboration between individuals with widely varying expertise. Communication between these individuals is facilitated by conceptual models. Conceptual models are early stage artifacts that integrate

Baseline Assessment of 25-Hydroxyvitamin D Assay Performance: A Vitamin D Standardization Program (VDSP) Interlaboratory Comparison Study

Christopher T. Sempos, Stephen Wise, Karen W. Phinney, Susan Tai, Johanna Camara, Gary L. Myers, Ramon Durazo-Arvizu, Lu Tian, John H. Eckfeldt, Andrew N. Hoofnagle, W. Greg Miller, Lorin M. Bachmann, Ian S. Young, J Pettit, G. Caldwell, A Liu, S P. Brooks, K. Sarafin, M. Thamm, C. Scheidt-Nave, G. B. Mensink, M. Busch, M. Rabenberg, Kevin Cashman, Mairead Kiely, Michael Kinsella, K Galvan, J. Y. Zhang, K OH, S. W. Lee, C. L. Jung, L. Cox, G. Goldberg, K. Guberg, S. Meadows, A. Prentice, G. Swan, A. Tedstone, Graham D. Carter, Julia C. Jones, P. Brannon, R. M. Lucas, P. M. Crump, Glenville Jones, E. Cavalier, Joyce Merkel, J. M. Betz
The Vitamin D Standardization Program (VDSP) coordinated an interlaboratory study to assess the comparability of measurements of total 25-hydroxyvitamin D [25(OH)D] in human serum, which is the primary marker of vitamin D status. A set of 50 individual

Combinatorial and MC/DC Coverage Levels of Random Testing

August 18, 2017
Author(s)
Sergiy Vilkomir, Aparna Alluri, D. Richard Kuhn, Raghu N. Kacker
Software testing criteria differ in effectiveness, numbers of required test cases, and processes of test generation. Specific criteria are often compared with random testing as the simplest basic approach and, in some cases, random testing shows a

Combinatorial Testing of Full Text Search in Web Applications

August 18, 2017
Author(s)
M S Raunak, David R. Kuhn, Raghu N. Kacker
Database driven web applications are some of most widely developed systems today. Testing these applications effectively and discovering difficult-to-find bugs continues to be a challenge for software engineers. In this paper, we show that combinatorial

August 18, 2017
Author(s)
Eite Tiesinga, B Sawyer, M Horvath, A Deb, N Kjaergaard
Magnetically tunable Feshbach resonances in ultracold atomic systems are chiefly identified and characterized through time consuming atom loss spectroscopy. We describe an off-resonant dispersive optical probing technique to rapidly locate Feshbach
