Improved interspecies optical clock comparisons through differential spectroscopy

November 28, 2022
Author(s)
May E. Kim, Will McGrew, Nicholas Nardelli, Ethan Clements, Youssef Hassan, Xiaogang Zhang, Jose Valencia, Holly Leopardi, David Hume, Tara Fortier, Andrew Ludlow, David Leibrandt
Comparisons of high-accuracy optical atomic clocks \citeLudlow2015} are essential for precision tests of fundamental physics \citeSafronova2018}, relativistic geodesy \citeMcGrew2018, Grotti2018, Delva2019}, and the anticipated redefinition of the SI

Voices of First Responders: How to Facilitate Adoption and Usage of Communication Technology - An Integrated Analysis of Qualitative and Quantitative Findings

November 28, 2022
Author(s)
Yee-Yin Choong, Kerrianne Buchanan, Shanee Dawkins, Sandra Spickard Prettyman
The Nationwide Public Safety Broadband Network (NPSBN) is being developed to provide a dedicated network for the use of first responders during incident response. A wave of new communication technologies compatible with the NPSBN is on the horizon, as

Development of a Diffusion Mobility Database for Co-based Superalloys

November 27, 2022
Author(s)
Greta Lindwall, Kil-Won Moon, Carelyn E. Campbell, Maureen E. Williams, Whitney Tso
To facilitate the development of high-temperature Co-based - superalloys, a Co-Ni based diffusion mobility database is developed for the eight component FCC (Face Centered Cubic) system of Co-Al-W-Ni-Cr-Ti-Ta-Re. A CALPHAD approach is used to represent

Validation of and Optimization with a Vapor Compression Cycle Model Accounting for Refrigerant Thermodynamic and Transport Properties: With Focus on Low GWP Refrigerants for Air-Conditioning

November 26, 2022
Author(s)
Harrison M. Skye, Piotr A. Domanski, Riccardo Brignoli, SANGHUN LEE, Heunghee Bae
CYCLE_D-HX is a semi-theoretical model that simulates the performance of a vapor-compression cycle with forced-convection heat exchangers for specified temperature profiles of the heat source and heat sink. In this study, we validated CYCLE_D-HX using

The Path to Cloud Federation through Standardization

November 25, 2022
Author(s)
Robert B. Bohn
This paper describes the efforts of the NIST Cloud Computing Program in the development of understanding the federated cloud concept through the creation of a reference architecture, cooperation with the IEEE and resulting in the publication IEEE 2302-2021

Reflow transfer for conformal three-dimensional microprinting

November 24, 2022
Author(s)
Gary Zabow
From microcircuits to metamaterials, micropatterning surfaces adds valuable functionality. For non-planar surfaces, however, incompatibility with conventional microlithography requires transferring originally planar micropatterns onto those surfaces but

Deep Learning Image Analysis of Nanoplasmonic Sensors: Toward Medical Breath Monitoring

November 23, 2022
Author(s)
Yangyang Zhao, Boqun Dong, Kurt D. Benkstein, Lei Chen, Kristen L. Steffens, Stephen Semancik
Sensing biomarkers in exhaled breath offers a potentially portable, cost-effective, and noninvasive strategy for disease diagnosis screening and monitoring, while high sensitivity, wide sensing range, and target specificity are critical challenges. We

Constructing quantum many-body scar Hamiltonians from Floquet automata

November 22, 2022
Author(s)
Michael Gullans, Pierre-Gabriel Rozon, Kartiek Agarwal
We provide a systematic approach for constructing approximate quantum many-body scars (QMBS) starting from two-layer Floquet automaton circuits that exhibit trivial many-body re- vivals. We do so by applying successively more restrictions that force local

Nonlinear excitations in ferrites

November 22, 2022
Author(s)
Pavel Kabos
This book chapter describes the processes leading to nonlinear excitations in ferrites at high power levels. We start from equation of motion that include nonlinear terms leading to nonlinear processes. First and second order Suhl instabilities for

Digital Investigation Techniques: A NIST Scientific Foundation Review

November 21, 2022
Author(s)
James R. Lyle, Barbara Guttman, John Butler, Kelly Sauerwein, Christina Reed, Corrine Lloyd
This document is an assessment of the scientific foundations of digital forensics. We examined descriptions of digital investigation techniques from peer-reviewed sources, academic and classroom materials, technical guidance from professional organizations

Encouraging and Enabling Mutual Ownership in a RSE Community of Practice

November 21, 2022
Author(s)
Miranda Mundt, Jonathan Bisila, Jonathan E. Guyer, Daniel Howard, Daniel S. Katz, Reed Milewicz, Henry Schreiner, Joshua Teves, Chris Wiswell
The explosion of Research Software Engineers (RSEs) in the United States created the opportunity to form communities of practice (CoP), groups which share a passion for an activity and learn how to do it better as they interact regularly, specifically to

Vacancy-Driven Disorder and Elevated Dielectric Response in the Pyrochlore Pb 1.5 Nbd2^O 6.5

November 21, 2022
Author(s)
Uyen Dang, Jake O'Hara, Hayden Evans, Daniel Olds, Juan Chamorro, Daniel Hickox-Young, Geneva Laurita, Robin Macaluso
Lone-pair driven distortions are a hallmark of many technologically-important lead (Pb)-based materials. The role of Pb 2+ in polar perovskites is well understood and easily manipulated for applications in piezo- and ferroelectricity, but the control of
