This report documents an experimental program designed to collect data and information to evaluate the performance of models developed to estimate the electrical high energy arcing fault (HEAF) hazard. This report covers full-scale laboratory experiments

Global Community Technology Challenge (GCTC) Strategic Plan 2024-2026

June 28, 2024
Author(s)
Michael Dunaway, Thomas Roth, Edward Griffor, David A. Wollman
This document provides a strategy and a project plan for the Global Community Technology Challenge, a federal smart cities program led by the Smart Connected Systems Division at the National Institute of Standards and Technology, an agency of the U.S

Perfect cheating is impossible for single-qubit position verification

June 28, 2024
Author(s)
Carl A. Miller, Yusuf Alnawakhtha
In quantum position verification, a prover certifies her location by performing a quantum computation and returning the results (at the speed of light) to a set of trusted verifiers. One of the very first protocols for quantum position verification was

Leveraging Combinatorial Coverage in the Machine Learning Product Lifecycle

June 27, 2024
Author(s)
Jaganmohan Chandrasekaran, erin lanus, tyler cody, laura freeman, Raghu N. Kacker, M S Raunak, D. Richard Kuhn
The data-intensive nature of machine learning (ML)-enabled systems introduces unique challenges in test and evaluation. We present an overview of combinatorial coverage, exploring its applications across the ML-enabled system lifecycle and its potential to

Exact and approximate fluxonium array modes

June 26, 2024
Author(s)
Stephen Sorokanich, Neill Warrington, Max Hays
We present an exact solution for the array modes of fluxonium. This solution holds for arrays of any length and ground capacitance. Array mode energies are determined by convex combinations of Chebyshev polynomials and their spatial profiles are plane

Measuring the Exploitation of Weaknesses in the Wild

June 26, 2024
Author(s)
Peter Mell, Irena Bojanova, Carlos Eduardo Cardoso Galhardo
Identifying the software weaknesses exploited by attacks supports efforts to reduce developer introduction of vulnerabilities and to guide security code review efforts. A weakness is a bug or fault type that can be exploited through an operation that

Cannabis Laboratory Quality Assurance Program: Exercise 2 Cannabinoid Final Report

June 25, 2024
Author(s)
Andrea Yarberry, Melissa M. Phillips, Walter Brent Wilson
NIST launched a Cannabis Laboratory Quality Assurance Program (CannaQAP) in 2020 to assist laboratories in demonstrating and improving cannabis (hemp and marijuana) measurement comparability and competence. CannaQAP provides tools that allow analysts and

NIST Conference Papers Fiscal Year 2023

June 24, 2024
Author(s)
Kathryn Miller, Julie Jew, Myriam S. Dilawari
This Special Publication represents the work of researchers at professional conferences, as reported by NIST employees in Fiscal Year 2023 (October 1, 2022–September 30, 2023).

System Vicarious Calibration requirements for satellite ocean colour missions targeting climate and global long-term operational applications

June 24, 2024
Author(s)
B. Carol Johnson, Giuseppe Zibordi, Ewa Kwiatkowska, Kenneth Voss, Frederic Melin, David Antoine, Menghua Wang, Shuguo Chen, Constant Mazeran, Brian Barnes, Jee-Eun Min
System Vicarious Calibration (SVC) is the technique that maximizes the accuracy of satellite ocean colour data products by minimizing the impact of inaccuracies affecting the absolute radiometric calibration of the space sensor and the atmospheric

Certification of Standard Reference Material(R) 1955a Homocysteine in Frozen Human Serum

June 21, 2024
Author(s)
Carolyn Burdette, Elena Wood, Jerome Mulloor, Michael Nelson, Blaza Toman, Aaron Urbas
Standard Reference Material (SRM) 1955a Homocysteine in Frozen Human Serum is intended for use in validating homocysteine measurement procedures used by in vitro diagnostics manufacturers, reference laboratories, and clinical laboratories in the United

Conformal Flame Retardant Coating Systems

June 21, 2024
Author(s)
Thomas Kolibaba, Federico Carosio, Jaime Grunlan
Surface coatings represent an important class of fire protective treatments. When deposited conformally, these treatments offer extremely effective fire protection, especially to high surface area substrates (e.g., textiles and foams). Additionally, use of

Characterization of Reference Material 8210: Hemp Plant

June 20, 2024
Author(s)
Colleen E. Bryan Sallee, Walter Brent Wilson, Charles Barber, Monique Johnson, Jenna Klingsick, Jerome Mulloor, Blaza Toman, Elena Wood, Laura Wood, Andrea Yarberry
The National Institute of Standards and Technology (NIST) Reference Material (RM) 8210 Hemp Plant delivers non certified values for cannabinoids and toxic elements in a dried ground hemp plant material to help cannabis and forensic laboratories for use as

Vertically Graded FeNi Alloys with Low Damping and a Sizeable Spin-Orbit Torque

June 14, 2024
Author(s)
Rachel Maizel, Shuang Wu, Purnima P. Balakrishnan, Alexander Grutter, Christy Kinane, Andrew Caruana, Prabandha Nakarmi, Bhuwan Nepal, David Smith, Youngmin Lim, Juila Jones, Wyatt Thomas, Jing Zhao, F. Michel, Tim Mewes, Satoru Emori
Energy-efficient spintronic devices require a large spin-orbit torque (SOT) and low damping to excite magnetic precession. In conventional devices with heavy-metal/ferromagnet bilayers, reducing the ferromagnet thickness to ∼1 nm enhances the SOT but drama

Viscoelastic Assessment Method of Polymeric Foams under Cyclic Fatigue

June 14, 2024
Author(s)
Moira M Foster, Daniel C Morrison, Alexander Landauer, Mark Herynk, Leslie Lamberson
Many energy absorption applications utilize flexible polymeric foams for their viscoelastic properties. It is desired that the material will perform consistently across repeated compression cycles. This study examines the effect of fatigue at low strain
