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
Author(s)
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

Neutron Scattering and Spectroscopic Studies of Hydrogen Adsorption in Cr 3 (BTC) 2 - A Metal-Organic Framework with Exposed Cr 2+ Sites

April 1, 2011
Author(s)
Kenji Sumida, Jae-Hyuk Her, Mircea Dinca, Leslie J. Murray, Jennifer M. Schloss, Christopher J. Pierce, Benjamin A. Thompson, Stephen A. FitzGerald, Craig Brown, Jeffrey R. Long
Microporous metal-organic frameworks possessing exposed metal cation sites on the pore surface are of particular interest for high-density H 2 storage at ambient temperatures, owing to the potential for H 2 binding at the appropriate isosteric heat of
