Flexures for Kibble balances: Minimizing the effects of anelastic relaxation

July 1, 2024
Author(s)
Lorenz Keck, Stephan Schlamminger, Rene Theska, Frank Seifert, Darine El Haddad
Modern weighing cells would not be possible without flexure technology. Flexures are thin metal strips that form pivots, and they can be engineered to bend in a prescribed fashion, producing a desired restoring torque. In contrast to other pivots, flexures

Report on High Energy Arcing Fault Experiments - International Experimental Results from Bus Duct and Switchgear Enclosures

July 1, 2024
Author(s)
Gabriel Taylor, Anthony D. Putorti Jr., Scott Bareham, Christopher U. Brown, Wai Cheong Tam, Michael Heck, Lucy Fox, Stephen Fink, Michael Selepak, Edward Hnetkovsky, Nicholas Melly, Kenneth Hamburger, Kenneth Miller
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

Single-Component Superconductivity in UTe2 at Ambient Pressure

July 1, 2024
Author(s)
Florian Theuss, Avi Shragai, Gael Grissonnanche, Ian Hayes, Shanta Saha, Yun Eo, Alonso Suarez, Tatsuya Shishidou, Nicholas Butch, Johnpierre Paglione, B. Ramshaw
The microscopic mechanism of Cooper pairing in a superconductor leaves its fingerprint on the symmetry of the order parameter. UTe2 has previously been inferred to have a multi-component order parameter, in part due to the apparent presence of a two-step

Assessing Structural Performance Using Energy

June 30, 2024
Author(s)
Kevin K F Wong
Buildings in seismic regions are designed to sustain significant damage during major earthquakes with collapse. Traditional linear design procedures use a force-based approach to size the building structural members. Alternatively, performance-based

Building Seismic Stability - Code Provisions vs. Inelastic Behavior

June 30, 2024
Author(s)
Larry Fahnestock, Shitao Shi, Matthew Speicher
In a building, seismic stability is provided when the internal restoring forces resist the effective earthquake forces plus the destabilizing effects of gravity that arise when the building displaces laterally. Although this concept can be succinctly

Functional Recovery of Lifeline Infrastructure System Services

June 30, 2024
Author(s)
Craig Davis, Andrew Herseth, Katherine Johnson, Ayse Hortacsu
Services provided by lifeline infrastructure systems are critical to the recovery of social functions after an earthquake. Lifeline infrastructure includes water, wastewater, drainage, electric power, communications, gas and liquid fuels, solid waste, and

Lessons from the 2023 Southeast Turkiye Earthquakes: A Study on Damaged RC Buildings Considering the Hassan Index

June 30, 2024
Author(s)
Cemalettin Donmez, Jeff Dowgala, Meltem Eryilmaz-Yildirim, Muhammet Fethi Gullu, Lissette Iturburu, Fahri Baran Koroglu, Remy Lesquesne, Baki Ozturk, Santiago Pujol, Julian Rincon, Chungwook Sim, Matthew Speicher
A survey was conducted across 10 cities in Southeast Türkiye to classify damage in 242 reinforced concrete (RC) buildings constructed in the last 15 years, ranging from 2 to 16 stories. The 'robustness' of these buildings was quantified using ratios of

Effect of Micellar Morphology on the Temperature-Induced Structural Evolution of ABC Polypeptoid Triblock Terpolymers into Two-Compartment Hydrogel Network

June 28, 2024
Author(s)
Naisheng Jiang, Tianyi Yu, Meng Zhang, Bailee Barrett, Haofeng Sun, Jun Wang, Ying Luo, Garrett Sternhagen, Sunting Xuan, Guangcui Yuan, Elizabeth Kelley, Shuo Qian, Peter Bonnesen, Kunlun Hong, Dongcui Li, Donghui Zhang
We investigated the temperature-dependent structural evolution of thermoreversible triblock terpolypeptoid hydrogels, namely poly(N-allyl glycine)-b-poly(N-methyl glycine)-b-poly(N-decyl glycine) (AMD), using small-angle neutron scattering (SANS) with

Four terminal-pair measurements of ceramic capacitors

June 28, 2024
Author(s)
Stephan Schlamminger, Yicheng Wang, Andrew Koffman, Jordan Love
Expanding on our previous work on four terminal-pair air capacitors, we present a model for the frequency-dependent capacitance of ceramic capacitors for values ranging from 10 nF to 10 uF. Two measurements are necessary for the complete model. First, the

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

Single-Phase L10-Ordered High Entropy Thin Films with High Magnetic Anisotropy

June 28, 2024
Author(s)
Willie Beeson, Dinesh Bista, Huairuo Zhang, Sergiy Krylyuk, Albert Davydov, Gen Yin, Kai Liu
The vast high entropy alloy (HEA) composition space is promising for discovery of new material phases with unique properties. We explore the potential to achieve high magnetic anisotropy materials in single-phase HEA thin films. Thin films of FeCoNiMnCu

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

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
