Towards a Global Agenda for Fire Research

December 1, 2001
Author(s)
J E. Snell
… led by Dr. William Pitts of the National Institute of Standards and Technology (NIST), on heat flux measurement. (I …

Radiometric Characterization and Calibration of the Marine Optical System (MOS) for the Marine Optical Buoy (MOBY) Project

October 1, 2000
Author(s)
C Habauzit, Steven W. Brown, Keith R. Lykke, B. Carol Johnson, M Yarbrough, M Feinholz, D K. Clark
The scientific objective of the Marine Optical Buoy (MOBY) project is to measure the downwelling spectral irradiance, E d, and the upwelling spectral radiance, L u, at various depths in the ocean. From these measurements, other quantities can be derived

Measurements of diffusion coefficients for rubidium--inert gas mixtures using coherent scattering from optically pumped population gratings

March 12, 2025
Author(s)
Alex Pouliot, E. Chomen-Ramos, G. Carlse, T. Vacheresse, J. Randhawa, L. Marmet, A. Kumarakrishnan, Jacek Klos, Eite Tiesinga
We present comprehensive determinations of diffusion coefficients $D$ at $T=24$ $\degree$C for trace amounts of naturally abundant Rb atoms in inert, naturally abundant He, Ne, N$_2$, Ar, Kr, and Xe buffer gases using a single measurement technique. They

Expansivity of fused quartz glass measured within 6 x 10^-10 K^-1

September 11, 2024
Author(s)
Patrick Egan
A method is described to measure the thermal expansion coefficient of fused quartz glass. The measurement principle is to monitor the change in resonance frequency of a Fabry–Perot cavity as its temperature changes; the Fabry–Perot cavity is made from

Dissemination of UTC(NIST) over 20 km of commercial optical fiber with active phase stabilization

May 2, 2024
Author(s)
Jacob VanArsdale, Matthew J. Deutch, Michael A. Lombardi, Glenn Nelson, Jeffrey Sherman, James Spicer, William Yates, Dylan Yost, Samuel Brewer
We demonstrate the transfer of a cesium frequency standard steered to UTC(NIST) over 20 km of dark telecom optical fiber. Our dissemination scheme uses an active stabilization technique with a phase-locked voltage-controlled oscillator. Out-of-loop

Correlating Near-Infrared Spectra to Bulk Properties in Polyolefins

February 28, 2024
Author(s)
Bradley Sutliff, Shailja Goyal, Tyler Martin, Peter Beaucage, Debra Audus, Sara Orski
The industry standard for sorting plastic wastes is near-infrared (NIR) spectroscopy, which offers rapid and nondestructive identification of various plastics. However, NIR does not provide insights into the chain composition, conformation, and topology of

Cybersecurity Framework Profile for Hybrid Satellite Networks (HSN)

Dan Mamula, Karri Meldorf, Joseph Brule, O'Ryan Lattin, John Wiltberger, Sam Sepassi, Rory Jennings, Chris Thorpe, John Dombrowski, Jim McCarthy
… and other interested parties, the National Institute of Standards and Technology (NIST) has developed the HSN …

Symplectic geometry and circuit quantization

April 17, 2023
Author(s)
Andrew Osborne, Trevyn Larson, Sarah Jones, Raymond Simmonds, Andras Gyenis, Andrew Lucas
Circuit quantization is an extraordinarily successful theory that describes the behavior of quantum circuits with high precision. The most widely used approach of circuit quantization relies on introducing a classical Lagrangian whose degrees of freedom
