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

Towards a consensus on a continuous Coordinated Universal Time

November 25, 2022
Author(s)
Judah Levine, Patrizia Tavella, Martin Milton
This paper discusses the considerations that were important in 1972, when the current leap second system was adopted, to maintain UTC, the international reference time scale, closely connected to UT1 – a time scale based on the rotation of the Earth

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

Phase-transition-induced Thermal Hysteresis in Type-II Weyl Semimetals MoTe2 and Mo(1-x)W(x)Te2

November 19, 2022
Author(s)
Md Sabbir Akhanda, Sergiy Krylyuk, Diane Dickie, Albert Davydov, Fei Han, Mingda Li, Mona Zebarjadi
The resistivity versus temperature measurement is commonly used for identifying temperature-induced phase change and the resulting hysteresis loop. While the resistance is influenced by both the density of states and the carrier lifetimes, the Seebeck

Efficient Parameter Exploration of Simulation Studies

November 18, 2022
Author(s)
Megan Olsen, M S Raunak
Simulation is a useful and effective way to analyze and study complex, real-world systems. It allows researchers, practitioners, and decision makers to make sense of the inner working of a system that involves many factors often resulting in some sort of

Optical Atomic Clock aboard an Earth-orbiting Space Station (OACESS): Enhancing searches for physics beyond the standard model in space

November 18, 2022
Author(s)
Vladimir Schkolnik, Dmitry Budker, Oliver Farttman, Victor Flambaum, Leo Hollberg, Tigran Kalaydzhyan, Shimon Kolkowitz, Markus Krutzik, Andrew Ludlow, Nathan R. Newbury, Christopher Pyrlik, Laura Sinclair, Yevgeny Stadnik, Ingmari Tietje, Jun Ye, Jason Williams
We present a concept for a high-precision optical atomic clock (OAC) operating on an Earth-orbiting space station. This pathfinder science mission will compare the space-based OAC with one or more ultra-stable terrestrial OACs to search for space-time
