A negative-response strain sensor towards wearable microclimate changes for body area sensing networks

January 31, 2023

Author(s)

Jing Liu, Junze Zhang, Zeyu Zhao, Yanping Liu, Wai Cheong Tam, Zekun Liu, Gang Li

Wearables and strain sensors have attracted much attention for applications in monitoring human motions and health. However, state-of-the-art sensors lack sensing reliability in changing temperature and humidity conditions. In this study, we design and

Additive manufacturing titanium powder oxygen variation within a single powder bed due to differences in powder size and oxygen content

January 31, 2023

Author(s)

Nicholas Derimow, Elisabeth Mansfield, Jason Holm, Nik Hrabe

Thermogravimetric analysis of Ti-6Al-4V powders (virgin Grade 5 and a once used Grade 23) was conducted up to 800 C in an industrial grade Ar environment. A standard starting particle size distribution (PSD) for electron beam powder-bed fusion (PBF-EB)

Complete collision data set for electrons scattering on molecular hydrogen and its isotopologues: IV. Vibrationally-resolved ionization of the ground and excited electronic states.

January 31, 2023

Author(s)

Yuri Ralchenko, Barry I. Schneider, Liam Scarlett, Eric Jong, Igor Bray, Starsha Odelia, Mark Zammit, Dmitry Fursa

We present a comprehensive set of vibrationally-resolved cross sections for electron-impact ionization of molecular hydrogen and its isotopologues (H2, D2, T2, HD, HT, and DT) in both the ground and excited electronic states. We apply the adiabatic-nuclei

Foundational PNT Profile: Applying the Cybersecurity Framework for the Responsible Use of Positioning, Navigation, and Timing (PNT) Services

January 31, 2023

Author(s)

James McCarthy, Ya-Shian Li-Baboud, Joseph Brule, Karri Meldorf

The national and economic security of the United States (U.S.) is dependent upon the reliable functioning of the nation's critical infrastructure. Positioning, Navigation, and Timing (PNT) services are widely deployed throughout this infrastructure. In a

Separable Shape Tensors for Aerodynamic Design

January 31, 2023

Author(s)

Zachary J. Grey, Andrew Glaws, Olga Doronina

Airfoil shape design is a classical problem in engineering and manufacturing. In this work, we combine principled physics-based considerations for the shape design problem with modern computational techniques using a data-driven approach. Modern and

Standards of Seismic Safety for Existing Federally Owned and Leased Buildings; ICSSC Recommended Practice 10 (RP 10-22)

January 31, 2023

Author(s)

John Harris

RP 10 allows federal agencies to identify conditions in an existing building that may pose unacceptable seismic risks to the agency in case of undesirable performance of the building during an earthquake. Agency exposure to unacceptable risks is generally

Design Guide for New Tornado Load Requirements in ASCE 7-22

January 30, 2023

Author(s)

Erik Perfetto, James Taylor, Karah Osburn, Brian O'Connor, Marc Levitan, Jennifer Mitchell

This instructional guidance is for design professionals and building officials to help them determine when a building or other structure is required to be designed to minimum tornado loads and how to calculate design tornado forces. This guide is in

Handout: Users Are Not Stupid: 6 Cybersecurity Pitfalls Overturned

January 30, 2023

Author(s)

Julie Haney, Susanne M. Furman

The cybersecurity community tends to focus and depend on technology to solve today's cybersecurity problems, often without taking into consideration the human element - the key individual and social factors impacting cybersecurity adoption. This handout

High-Throughput DFT-Based Discovery of Next Generation Two Dimensional (2D) Superconductors

January 30, 2023

Author(s)

Daniel Wines, Kamal Choudhary, Adam Biacchi, Kevin Garrity, Francesca Tavazza

High-throughput density functional theory (DFT) calculations allow for a systematic search for conventional Bardeen–Cooper–Schrieffer (BCS) superconductors. With the recent interest in two-dimensional (2D) superconductors, we extend our previously

NIST Handbook 44 - Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices (2023 Ed.)

January 30, 2023

Author(s)

Tina Butcher, Richard A. Harshman, Gloria Lee, Juana Williams, Jan Konijnenburg, Lisa Warfield, Katrice Lippa, Shelby Bowers, Elizabeth Benham

NIST Handbook 44 includes specifications, tolerances, and other technical requirements for weighing and measuring devices. These requirements are intended to encourage the design, installation, testing, and use of weighing and measuring devices that

Photon echoes using atomic frequency combs in Pr:YSO -- experiment and semiclassical theory

January 30, 2023

Author(s)

Zachary H. Levine, Aditya N. Sharma, Kumel H. Kagalwala, Martin A. Ritter, Eli J. Weissler, Elizabeth A. Goldschmidt, Alan Migdall

Photon echoes in rare-earth-doped crystals are studied to understand the challenges of making broadband quantum memories using the atomic frequency comb (AFC) protocol in systems with hyperfine structure. The hyperfine structure of Pr3+ poses an obstacle
