Characterization of an Extensive Interface on Vitronectin for Binding to Plasminogen Activator Inhibitor-1: Adoption of Structure in an Intrinsically Disordered Region

December 24, 2019
Author(s)
Letitia O. Puster, Christopher B. Stanley, Vladmir N. Uversky, Joseph E. Curtis, Susan T. Krueger, Yuzhuo Chu, Cynthia B. Peterson
Small-angle neutron scattering (SANS) measurements were used to characterize vitronectin, a protein found in human plasma and tissues that functions in regulating cell adhesion and migration, as well as proteolytic cascades that affect blood coagulation

Where do we start? Guidance for technology implementation in maintenance management for manufacturing

Author(s)
Michael P. Brundage, Thurston B. Sexton, Melinda Hodkiewicz, Katherine C. Morris, Jorge Arinez, Farhad Ameri, Jun Ni, Guoxian Xiao
Recent efforts in Smart Manufacturing (SM) have proven quite effective at elucidating system behavior using sensing systems, communications and computational platforms, along with statistical methods to collect and analyze real-time performance data

Structural and Dynamical Order of a Disordered Protein: Molecular Insights into Conformational Switching of PAGE4 at the Systems Level

February 1, 2019
Author(s)
Xingcheng Ling, Prakash Kulkarni, Federico Bocci, Nicholas Schafer, Susmita Roy, Min-Yeh Tsai, Yanan He, Yihong Chen, Krithika Rajagopalan, Steven Mooney, Yu Zeng, Keith Weninger, Alexander Grishaev, Jose Onuchic, Herbert Levine, Peter Wolynes, Govindan Rangarajan, Vladimir Uversky, John Orban, Mohit Jolly
Folded proteins show a high degree of structural order and undergo (fairly constrained) collective motions related to their functions. On the other hand, intrinsically disordered proteins (IDPs), while lacking a well-defined three-dimensional structure, do

A more efficient method for calibrating discrete element method parameters for simulations of metallic powder used in additive manufacturing

October 31, 2018
Author(s)
Stephen R. Geer, Michelle Bernhardt, Edward Garboczi, Justin Whiting, Alkan Donmez
Laser powder bed fusion (LPBF) is an additive manufacturing (AM) process that uses a high-power laser to selectively melt metal powder that has been spread, layer-by-layer, to create parts with highly complex features. Because of the strong influence that

The NISTmAb Tryptic Peptide Spectral Library for Monoclonal Antibody Characterization

March 6, 2018
Author(s)
Qian Dong, Yuxue Liang, Xinjian Yan, Sanford Markey, Yuri Mirokhin, Dmitrii V. Tchekhovskoi, Tallat H. Bukhari, Stephen E. Stein
We describe the creation of a mass spectral library composed of all identifiable spectra derived from the tryptic digest of a therapeutic monoclonal antibody. The NISTmAb library is a unique reference peptide spectral library developed from a total of six

Metagenomic assembly through the lens of validation: a review of recent advances in assessing and improving the quality of genes and genomes assembled from metagenomes.

August 6, 2017
Author(s)
Nathanael Olson, Chris M. Hill, Vistoria Cepeda-Espinoza, Jay Ghurye, Sergey Koren, Todd J. Treangen, Mihai Pop
Metagenomic samples are snapshots of complex ecosystems at work. These samples often involve hundreds of bacteria from known and unknown species, contain multiple strain variants, and vary greatly both within and across environments. Many microbes found in

Local Distribution and Calibration of Timing Signals at NIST

January 31, 2017
Author(s)
Joshua J. Savory, Liz C. Forero, Kristopher Maurer, Stefania Romisch
The National Institute of Standards and Technology (NIST) timescale produces a real-time realization of UTC(NIST) in the form of a pulse-per-second (PPS) time signal and a 5 MHz frequency reference. The timing signals are distributed to the international

High-temperature material constitutive models for structural-fire analysis

June 7, 2016
Author(s)
Chao Zhang, Lisa Choe, John L. Gross
The applicability of three steel constitutive models was evaluated using finite-element analyses and various member capacity equations. Three different high-temperature stress-strain models were compared: the model recently developed by the National

Using a Laser Tracker to Actively Coordinate the Motion of a 3m Industrial Robot to Within 50 Microns: An ongoing effort to accurately determine and correct positioning errors.

October 1, 2013
Author(s)
David R. Novotny, Joshua A. Gordon, Jason B. Coder, Jeffrey R. Guerrieri, Michael H. Francis
We are using industrial-grade robotics guided by a metrology-grade laser tracker to perform antenna calibrations at mmWave frequencies. We are using a 3 m-reach robot to spherically scan a milli-meter Wave (mmWave) probe around an antenna under test (AUT)

Comparing Face Recognition Algorithms to Humans on Challenging Tasks

October 17, 2012
Author(s)
P J. Phillips, Alice O'Toole, Xiaobo An, Joseph Dunlop, Vaidehi Natu
We compared face identifcation by humans and machines using images taken under a variety of uncontrolled illumination conditions in both indoor and outdoor settings. Natural variations in a person's day-to-day appearance (e.g., hair style, facial

Characterizing Dynamic Effects of Oscillator Power Cycling

November 14, 2011
Author(s)
David A. Howe, Danielle G. Lirette, Neil Ashby, Archita Hati, Craig W. Nelson
We create a measurement technique and metrics consistent with easy interpretation to be used in development of new oscillators specifically for applications in which the oscillator’s power is turned on and off. This is useful in predicting the performance

Predicting Human Behavior during Fires

October 4, 2011
Author(s)
Erica D. Kuligowski
Evacuation models, including engineering hand calculations and computational tools, are used to evaluate the level of safety provided by buildings during evacuation. Building designs and occupant procedures are based on the results produced from these

High-Resolution Infrared Spectra of Spiropentane, C5H8

September 15, 2011

Alfons Weber, J E. Price, K A. Coulterpark, Tony Masiello, Joseph W. Nibler, A Maki, Thomas A. Blake
Infrared spectra of spiropentane (C5H8) have been recorded at a resolution (0.002 cm-1) sufficient to resolve for the first time individual rovibrational lines. This initial report presents the ground state constants for this molecule determined from the
