Expanding the AI Evaluation Toolbox with Statistical Models

February 17, 2026
Author(s)
Andrew Keller, Kweku Kwegyir-Aggrey, Ryan Steed, Anita Rao, Julia Sharp, Amanda Bergman
Benchmarks are widely used to evaluate and compare the performance of artificial intelligence systems. However, some approaches to computing benchmark metrics produce invalid uncertainty estimates or make unrecognized assumptions about the evaluation

Hurricane Ian Data Synthesis Workshop Report

February 17, 2026
Author(s)
James LaDue, Daniel Cox, Marc Levitan, Mershad Amini, Sebastiao Figueira
This report documents the results of the Hurricane Ian Data Synthesis Workshop, held on June 6, 2023, at the American Society of Civil Engineers headquarters in Reston, Virginia. The purpose of the workshop, which was conducted in collaboration between

Demonstration of Near-Infrared Open-Path Absorption Spectroscopy for Water Vapor and Temperature Monitoring During Structure-to-Structure Fire Spread Experiments

February 13, 2026
Author(s)
Erin McCaughey, Monica Flores, Christopher Brown, Alexander Maranghides, J. Houston Miller, Diana Bailey
With increasing threats from wildfires in wildland urban interface (WUI) areas, novel approaches for the characterization of fire dynamics and their interactions with built structures have accelerated. Here, we demonstrate an open-path, near-infrared laser

2025 OIC Manufacturing 'Road Runner' Challenge

February 10, 2026
Author(s)
Catherine Cooksey, Michael Jacobson, Daniel Poitras, Luke Sandilands, Amy Rigatti, John Gilmore
Measurements are presented of the fabricated optical filters submitted to the Manufacturing Challenge organized in conjunction with Optica's Topical Meeting on Optical Interference Coatings, held in Tucson in May 2025. For this Ninth edition of the

Enhanced Detection of Acute Ischemic Stroke With Low-Field MRI

Annabel Sorby-Adams, Nandor Pinter, John Kirsch, Vinay Jaikumar, Olivia Nelson, Stephen Bacchi, Jennifer Guo, John Pitts, Vivien Lee, Keith Muir, Shahid Nimjee, Kathryn Keenan, Matthew Rosen, J. Eugenio Iglesias, Kevin Sheth, Joshua Goldstein, W. Taylor Kimberly

Alternative Fundamental Equation of State for Fluid Carbon Dioxide

February 2, 2026
Author(s)
Eric Lemmon, Allan Harvey, Robert Hellmann
We present a new fundamental equation of state for fluid carbon dioxide, which is an alternative to the current reference formulation published by Span and Wagner in 1996. The equation of state is formulated as the Helmholtz energy as a function of

Electrical interconnects for silicon spin qubits

February 2, 2026
Author(s)
Christopher White, Anthony Sigillito, Michael Gullans
Scalable spin qubit devices will likely require long-range qubit interconnects. We propose to create such an interconnect with a resistive topgate. The topgate is positively biased, to form a channel between the two dots; an end-to-end voltage difference

Patterns and gaps in co-benefit reporting in global adaptation research

January 30, 2026
Author(s)
Christina Gore, Caitlin Grady, Rithika Dulam, Dhanyasri Bolla, Anna Liu, Jennifer Helgeson
Adaptations to extreme weather events are increasing in prevalence across the globe. Adaptation actions can produce co-benefits, which are ancillary positive outcomes beyond the primary objectives of reducing risk and enhancing resilience. Despite growing

Bridging the Gap between Standards on Random Number Generation: Comparison of SP 800-90 Series and AIS 20/31

January 29, 2026
Author(s)
Elaine Barker, John Kelsey, Kerry McKay, Johannes Mittmann, Matthias Peter, Werner Schindler, Meltem Sonmez Turan
This report studies the cryptographic random number generation standards and guidelines written by BSI and NIST, namely AIS 20/31 and SP 800-90 Series. The aim of this report is to compare these publications, focusing on the similarities and differences of

DATA REQUIREMENTS FOR A DIGITAL TWIN OF A CNC MACHINE TOOL

January 29, 2026
Author(s)
Deogratias Kibira, Guodong Shao
Digital twins enable the intelligent operation of computer numerical control (CNC) machine tools from which a wide range of data can be collected using sensors and other Internet of Things (IoT) devices. Creating a valid digital twin for a specific purpose

The National Marine Mammal Tissue Bank Specimen Inventory Report

January 29, 2026
Author(s)
Jennifer Ness, Debra Ellisor, Jennifer Hoguet, Amanda Moors, Amanda Capuano, Rebecca Pugh
This report provides a brief background of the National Marine Mammal Tissue Bank (NMMTB), information on the composition of the collection, policies for specimen use, and links to a downloadable and searchable specimen inventory. The inventory covers

Wafer-Scale Micro-Knife Sealed Vacuum Cells for Quantum Devices

January 29, 2026
Author(s)
Megan Kelleher, Konrad Ziegler, Jeremy Robin, Lianxin Huang, Mitchel Button, Liam Mauck, Peter Brewer, Danny Kim, John Kitching, William McGehee, Travis Autry
Advanced integration technologies greatly enhance the prospects and reliability of practical quantum sensors, atomic clocks, and quantum information technologies. The performance and proliferation of these devices at chip-scale is contingent upon

Realization of two-dimensional discrete time crystals with anisotropic Heisenberg coupling

January 28, 2026
Author(s)
Eric Switzer, Niall Robertson, Nathan Keenan, Angel Rodriguez, Andrea D'Urbano, Bibek Pokharel, Talat Rahman, Oles Shtanko, Sergiy Zhuk, Nicolas Lorente
A discrete time crystal (DTC) is an out-of-equilibrium phase of matter that spontaneously breaks discrete time-translation symmetry. Previous studies have been limited to a set of models with Ising-like couplings - and mostly only in one dimension - thus

Scanned Squid Microscope with High-speed Electrical Connectivity

January 26, 2026
