End-effector Pose Extrapolation using Wireless Channel State Information

April 21, 2026
Author(s)
Karl Montgomery, Nathan Wei, Jing Geng, Mohamed Hany, Richard Candell
Wireless communications for real-time control is an emerging field. There are many advantages gained by replacing a wired link with wireless; however, wireless brings unique challenges. Applications may need to be designed with wireless communications in

Optical clock frequency ratios with uncertainty ? 3.2 * 10^-18

April 10, 2026
Author(s)
Alexander Aeppli, Willa Arthur-Dworschack, Kyle Beloy, Caitlin Berry, Tobias Bothwell, Angela Folz, Tara Fortier, Tanner Grogan, Youssef Hassan, Zoey Zimeng Hu, David Hume, Benjamin Hunt, Kyungtae Kim, Amanda Koepke, Dahyeon Lee, David Ray Leibrandt, Ben Lewis, Andrew Ludlow, Mason Marshall, Nicholas Nardelli, Harikesh Ranganath, Daniel Rodriguez Castillo, Jeffrey Sherman, Jacob Siegel, Suzanne Thornton, William Warfield, Jun Ye
We report high-precision frequency ratio measurements between optical atomic clocks based on 27Al+, 171Yb, and 87Sr. With total fractional uncertainties at or below 3.2 × 10−18, these measurements meet the milestone criteria for redefinition of the second

Ion-Pair Speciation in Aqueous Alkali Fluorides from Nuclear Magnetic Resonance of 19 F

April 9, 2026
Author(s)
Malgorzata Musial, Samantha Miller, Christopher Suiter, Heidi Klem, Eugene Paulechka, Kathleen Schwarz, Jason Widegren, Demian Riccardi
We demonstrate that a combination of multiscale modeling and experimental 19F NMR can be used to examine the molecular details of how ion-pair speciation changes with temperature and molality. Excellent agreement with experimental 19F NMR chemical shifts

Characterization of Electronic Stress-Induced Changes in Multi-Layer MoS2

April 6, 2026
Author(s)
R. Colby Evans, Riccardo Torsi, Pavel Kabos, Jason Holm, Jason Killgore, Paul Owiredu, Gurpreet Singh, Jerzy Sadowski, Angela Hight Walker, Elisabeth Mansfield
Transition metal dichalcogenides like molybdenum disulfide (MoS2) are compelling for next-generation electronic devices. In this work, we investigate the impact of electronic stress on MoS2 to illustrate that observational and phenomenological information

Ultra-High Speed Printing Regime in Laser Powder Bed Fusion of Highly Reflective Metals

April 5, 2026
Author(s)
Natalya Kublik, Laura Duenas Gonzalez, David Deisenroth, zhengtao gan, Bruno Azeredo
Additive manufacturing of highly reflective metals, such as copper and aluminum, often entail excessive energy losses, especially in laser powder bed fusion (LPBF). To compensate for reflected losses, high powered lasers and low scan speeds (i.e., ≤ 0.8 m

Formulating, Fitting and Fusing Fragility Functions (F5)

April 2, 2026
Author(s)
Mohammadamin Hariri Ardebili, Siamak Sattar
Fragility functions derived from nonlinear dynamic analysis are a central ingredient in seismic performance assessment and risk analysis of structural systems. This technical report revisits fragility functions from a unified perspective that addresses

Burning Rates of Individual Firebrands on Shredded Paper Beds

March 31, 2026
Author(s)
Savannah Wessies, Jiann Yang
Every year, homes and buildings are destroyed by wildland fires. In most situations, the structures are ignited by firebrands landing on a combustible surface within or in the direct vicinity of the structure. The mass burning rate, which is directly

Toward a Standardized Manufacturing Operation Management Ontology (MOMO): Findings from the NIST Workshop

March 30, 2026
Author(s)
Arkopaul Sarkar, Boonserm Kulvatunyou, Evan Wallace, Milos Drobnjakovic, Gabriela Henning, Ana Nikolov, Saruda Seeharit, Dusan Sormaz, Adlene Rebai, Yan Lu
The Manufacturing Operations Management Ontology (MOMO) aims to standardize operational management terminology across discrete, batch, and continuous manufacturing processes. Seeing similar ontologies being developed by the pharmaceutical (small molecule)

Studies Of Water Films and Carbonation Via Neutron Scattering and Infrared Adsorption: In Situ Studies of Mg(OH)2 and Ca(OH)2

March 24, 2026
Author(s)
Hubert King, Ryan Murphy, Avery Baumann, Robert Dalgliesh, Dirk Honecker, Gregory Smith
Small-angle neutron scattering was used to investigate structural evolution during the carbonation of Ca(OH)₂ and Mg(OH)₂ under humidified CO₂, using both H₂O and D₂O vapor. For Ca(OH)₂, carbonation led to a progressive increase in both nano- and meso

The 34th Text REtrieval Conference (TREC 2025)

March 24, 2026
Author(s)
Ian Soboroff, George Awad
TREC 2025 is the thirty-fourth edition of the Text REtrieval Conference (TREC). The main goal of TREC is to create the evaluation infrastructure required for large-scale testing of information retrieval (IR) technology. This includes research on best

NIST Special Database 302: Annotated Latent Distal Phalanxes

March 23, 2026
Author(s)
Gregory Fiumara, Matthew Schwarz, Jessica Heising, Jennifer Peterson, Kenneth Ko, Patricia Flanagan, Karen Marshall
National Institute of Standards and Technology (NIST) Special Database 302 contains 10,000 latent impression distal phalanx images. This collection of data came from the Intelligence Advanced Research Projects Activity's Nail to Nail Fingerprint Challenge
