Stephen Wise, Ekaterina Mineva, Christine Pfeiffer, Hubert Vesper, Etienne Cavalier, Stephenie Peters, Karen Galvin, Kevin Cashman, Andrew Norbert Hoofnagle, Hsuan-Chieh (Joyce) Liao, Emma Williams, Laura Briggs, Adam Kuszak, Grace Hahm, Johanna Camara
An interlaboratory comparison study was conducted among five laboratories for determination of 24,25-dihydroxyvitamin D3 [24,25(OH)2D3] in human serum using liquid chromatography - tandem mass spectrometry (LC-MS/MS) methods. The Centers for Disease

Bootstrap Metric for Quantifying the Depth Resolution of 3D Sensors

April 27, 2026
Author(s)
Prem Rachakonda, Hariharan Iyer, Marek Franaszek, Kamel Saidi
Depth resolution of a 3D imaging system or 3D sensor is defined as the smallest change in physical depth that causes a detectable change in the corresponding measured or derived depth. The ability of a sensor to resolve depth on a particular target is

Electron Spin Resonance Sensor for Portable and Adaptable Retrospective Dosimetry

April 24, 2026
Author(s)
Pragya Shrestha, Kin Cheung, Robert Gougelet, Stephen Moxim, Ileana Pazos, Jason Campbell
The demand for portable, versatile, cost-effective and high-performance tools for radiation dosimetry has increased in recent years. The development of a new, highly portable electron spin resonance (ESR) instrument represents a signifi-cant breakthrough

Quantum non-Markovian noise in randomized benchmarking of spin-boson models

April 24, 2026
Author(s)
Srilekha Gandhari, Michael Gullans
In non-Markovian systems, the current state of the system depends on the full or partial history of its past evolution. Owing to these time correlations, non-Markovian noise violates common assumptions in gate characterization protocols such as randomized

Development Toward Tungsten Transition-Edge Sensors with Improved Energy Resolution in the Optical/NIR Regime

April 22, 2026
Author(s)
Leaf Swordy, Adriana Lita, Benedikt Hampel, Daniel Swetz, Paul Szypryt, Douglas Bennett, Galen O'Neil, Michael Vissers, Joel Ullom, Richard Mirin, Martin Stevens
We formulate an energy resolution model for optical transition-edge sensors which combines aspects of existing models with the goal of better defining and constraining energy resolution optimization. The combined model is found to be in better agreement

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

Domain-engineered, aperiodically-poled KTiOPO4 for polarization-entangled photons

April 20, 2026
Author(s)
Paulina Kuo, Sesha Challa, Anouar Rahmouni, Dileep Venkatarama Reddy, Ori Levin, Noa Bloch
We demonstrate a high-quality source of polarization-entangled photons in aperiodically-poled KTiOPO_4 (KTP). The crystal is based on a phase-modulated domain-engineered design that allows two simultaneous downconversion processes, where the two processes

Examining Safe Intervention Windows for 18650 and 21700 Lithium-Ion Batteries under Heat Interruption Experiments

April 20, 2026
Author(s)
Wai Cheong Tam, Hongqiang Fang, Jian Chen, Qiuhong Wang, Christopher Brown, Md. Ismail Siddiqi Emon, Anthony Putorti
This study experimentally quantifies the safe intervention window (the time between the earliest thermal runaway indicator and ignition) for cylindrical lithium-ion batteries exposed to constant external heating. A total of 77 experiments were performed on

Foundational Cybersecurity Activities for IoT Product Manufacturers

April 20, 2026
Author(s)
Michael Fagan, Katerina Megas, Barbara Cuthill, Jeffrey Marron, Brad Hoehn
Internet of Things (IoT) products often lack product cybersecurity capabilities their customers—organizations and individuals—can use to help mitigate their cybersecurity risks. Manufacturers can help their customers by improving the securability of their

GROQ-seq Datasets Across Transcription Factors (LacI, RamR, VanR), T7 RNA Polymerase and TEV Protease

Aviv Spinner, Shwetha Sreenivasan, James McLellan, Svetlana Ikonomova, Dana Cortade, Simon d'Oelsnitz, Kristen Sheldon, Olga Vasilyeva, Nina Alperovich, Anjali Chadha, Lily Nematollahi, Andi Dhroso, Zach Sisson, Corey Hudson, Erika DeBenedictis, Peter Kelly, Amanda Reider Apel, David Ross, Catherine Baranowski
Predicting any protein's function from its sequence alone would be a significant breakthrough in molecular biology. Although machine learning approaches have sought to tackle this, their limited generalizability reflects the absence of sufficiently large

Redetermination of the Gravitational Constant with the BIPM torsion balance at NIST

April 16, 2026
Author(s)
Stephan Schlamminger, Leon Chao, Vincent Lee, Craig Shakarji, David Newell, Julian Stirling, Robert Cochrane, Clive Speake
We report the first replication of a high-precision measurement of the gravitational constant, $G$. The experiment employed the torsion balance originally designed and constructed at the International Bureau of Weights and Measures (BIPM) approximately
