RNA is the analyte targeted by nucleic acid amplification tests for SARS-CoV-2 virus, the causative agent of the COVID-19 pandemic. RNA concentration measured in respiratory specimens can vary by over nine orders of magnitude (1, 2). While RNA abundances

Radiation Pressure-based Laser Metrology Implementing an Electrostatic Force Balance

December 12, 2022
Author(s)
Brian Simonds, Kyle Rogers, Sven Schulze, David Newell, Gordon Shaw, Paul A. Williams, John Lehman
A primary standard force sensor and laser power meter are combined to achieve laser power traceability to Planck's constant by means of radiation pressure. We assess the statistical uncertainty for measurements of 1 kW, 2 kW, and 5 kW using an

Monte Carlo Augmented Channel Estimator

March 3, 2022
Author(s)
Alec Weiss, Atef Elsherbeni, Jeanne Quimby, Jake Rezac
We have developed a novel Monte Carlo-augmented channel estimator for millimeter-wave orthogonal frequency division multiplexing systems To better estimate and correct a transmitted orthogonal frequency division multiplexed signal by incorporating the

NIST IAD DSE Evaluation Plan 2018

New determination of the 229Th half-life

July 23, 2018
Author(s)
Richard Essex, Jacqueline L. Mann, Ronald Colle, Lizbeth Laureano-Perez, Megan E. Bennett, Heather Dion, Ryan P. Fitzgerald, Amy M. Gaffney, Amelie Hubert, Robert E. Steiner, Ross W. Williams, Alkiviadis Gourgiotis, William S. Kinman
A new determination of the 229Th half-life was made based on measurements of the 229Th massic activity of a high-purity solution for which the 229Th molality had previously been measured. The 229Th massic activity was measured by direct comparison with SRM

Kinetic Mechanism of 2,3,3,3-Tetrafluoropropene (HFO-1234yf) Combustion

July 16, 2018
Author(s)
Valeri I. Babushok, Gregory T. Linteris
A kinetic model for 2,3,3,3-tetrafluoropropene (HFO-1234yf) high temperature oxidation and combustion is proposed. It is combined with the GRI-Mech-3.0 model, with the previously developed model for 2-bromo-3,3,3-trifluoropropene (2-BTP), and with the NIST

Experimental Bounds on Classical Random Field Theories

December 10, 2014
Author(s)
Joffrey K. Peters, Sergey Polyakov, Jingyun Fan, Alan Migdall
Alternative theories to quantum mechanics motivate important fundamental tests of our understanding and description of the smallest physical systems. Here we place experimental limits on those classical field theories which result in power-dependent

Milligram Mass Metrology Using Electrostatics

August 25, 2014
Author(s)
Gordon A. Shaw, John A. Kramar
— Although mass has historically been defined using an artifact standard, other means of realization are possible. One alternative approach employs a precision electromechanical balance, using the SI electrical units to derive a force used to measure the

Long Term Air Quality Monitoring in a Net-Zero Energy Residential Test Facility Designed with Specifications for Low Emitting Interior Products

August 6, 2014
Author(s)
Dustin G. Poppendieck, Lisa C. Ng, Matthew P. Schlegel, Andrew K. Persily, Alfred Hodgson
This study evaluated the effectiveness of a low-VOC (volatile organic compounds) specification designed to minimize occupant exposures to indoor air pollutants in a net-zero energy research house meeting the ASHRAE Standard 62.2 ventilation requirements

Figures of Merit

June 4, 2014
Author(s)
Thomas J. Bruno
In the interpretation of results from a particular technique, one often must evaluate the performance of the measurement on the basis of objective measures that are called figures of merit. The following table provides a description of the more common

Economic Case Study: The Impact of NSTIC on the Internal Revenue Service

July 9, 2013
Author(s)
Gregory C. Tassey
The National Strategy for Trusted Identities in Cyberspace (NSTIC) offers a vision of more secure, efficient, and cost-effective authentication through widespread use of robust third-party credentials standardized to a national strategy. If successful
