Insitu Mass Burning Rates of Individual Firebrands

December 17, 2025
Author(s)
Savannah Wessies, Jiann Yang
Firebrands are a leading cause of structure ignitions in wildland-urban interface fires. Understanding the burning rates of firebrands can provide insight on the ability of firebrands to ignite the substrates they land on. Experiments were designed to

Mitigating Cybersecurity and Privacy Risks in Telehealth Smart Home Integration

December 17, 2025
Author(s)
Ronald Pulivarti, Kevin Littlefield, Sue Wang, Bronwyn Patrick, Ryan Williams
In-patient service demands have increased during a time when patients have experienced reduced access to hospital care. Hospital-at-Home (HaH) solutions provide an in-patient care experience for patients, which may result in reduced costs and improved

An In-depth Study Evaluating the Determination of CBD, D9-THC, D8-THC, and 25 Additional Cannabinoids in Cannabis Concentrates by Liquid Chromatography with Absorbance Detection

December 15, 2025
Author(s)
Walter Wilson, Arianna Romares, STEPHEN GOLDMAN
Cannabis revenue has risen in the United States (US) from $16.5B in 2018 to $45.4B in 2025 [1], which can be attributed to the legalization of hemp in 2018 with the passage of the Agricultural Improvement Act of 2018 (2018 Farm Bill) and the surge of

Chirped magneto-optical trap of molybdenum

December 12, 2025
Author(s)
Sai Naga Manoj Paladugu, Nickolas Pilgram, Stephen Eckel, Eric Norrgard
We have directly loaded a cryogenic beam of molybdenum atoms into a magneto-optical trap. By chirping the detuning of the trapping lasers, we were able to enhance the number of atoms loaded into the trap by more than a factor of 2. We optimize the trapped

Cooperative Multistatic Sensing Using 5G NR PRS Signal

December 12, 2025
Author(s)
Anirudha Sahoo, Amala Sonny, Steve Blandino, Tanguy Ropitault, David Griffith, Thao Nguyen, Nada Golmie
Integrated Sensing and Communications (ISAC) has gained momentum because it reuses hardware, spectrum, and waveforms meant for communication. ISAC in 5G New Radio (NR) systems is envisioned to enable a wide range of applications like intruder detection

Detection of molecular hydrogen in a neutron beam lifetime experiment

December 12, 2025
Author(s)
Jimmy Caylor, Ripan Biswas, Bret Crawford, Maynard Dewey, Nadia Fomin, Geoffrey Greene, Shannon Hoogerheide, Jose Hungria-Negron, Hans Mumm, Jeffrey Nico, Daniel Valete, Fred Wietfeldt, Joseph Zuchegno
One method of determining the free neutron lifetime involves the absolute counting of neutrons and trapped decay protons. In such experiments, a cold neutron beam traverses a segmented proton trap inside a superconducting solenoid while the neutron flux is

Robust AI Security and Alignment: A Sisyphean Endeavor?

December 12, 2025
Author(s)
Apostol Vassilev
This manuscript establishes information-theoretic limitations for robustness of AI security and alignment by extending Gödel's incompleteness theorem to AI. Knowing these limitations and preparing for the challenges they bring is critically important for

Validation in Forensic Science: Guiding Principles for the Collection and Use of Validation Data

December 12, 2025
Author(s)
Henry Swofford, Steven Lund, Barbara Guttman, Erica Romsos, Johannes Soons, Melissa Taylor, Hariharan Iyer, Peter Vallone, John Jones, Vincent Desiderio, John Butler, Sandra Koch, Robert Thompson, Gregory Fiumara, Edward Sisco, Kelly Sauerwein, Allison Getz, Robert Ramotowski
This document provides guidance to the forensic science community on method validation. Building on the definition of validation in ISO/IEC 17025, it explores the specific components of validation within a forensic science context and introduces five

High-Fidelity Quantum State Control of a Polar Molecular Ion in a Cryogenic Environment

December 9, 2025
Author(s)
Dalton Chaffee, Baruch Margulis, April Sheffield, Julian Schmidt, April Reisenfeld, David Ray Leibrandt, Dietrich Leibfried, Chin-wen Chou
We use a quantum-logic spectroscopy (QLS) protocol to control the quantum state of a CaH+ ion in a cryogenic environment that permits enhancement of rotational state lifetimes by an order of magnitude. By repeatedly and adaptively probing the molecule

Innocent Until Proven Guilty: The Case for Limiting 'Sequences of Concern' to Those with Demonstrated Pathogenic Function

December 9, 2025
Author(s)
Gene D. Godbold, Krista Ternus, Kevin Flyangolts, Nicole Wheeler, Michael Parker, Jacob Beal, Peter Carr, KEMPER TALLEY, Caitlin Jagla, Bryan Gemler, Craig Bartling, Rebecca Mackelprang, India Hook-Barnard, James Diggans, Samuel Forry, Sheng Lin-Gibson, Tyler Laird, Todd Treangen, Tessa Alexanian, Gregory Koblentz, Kevin Esvelt, Joshua Gil
Screening synthetic nucleic acid orders for sequences of concern is a necessary part of a healthy biosecurity regime, but it exacts costs for nucleic acid providers. Taxonomy is and will remain a critical part of the decision-making process for screening

Observation of a fault tolerance threshold with concatenated codes

December 9, 2025
Author(s)
Grace Sommers, Michael Foss-Feig, David Hayes, David Huse, Michael Gullans
We introduce a fault-tolerant protocol for code concatenation using a butterfly network architecture with high noise thresholds and low ancilla overhead to allow implementation on current devices. We develop a probability passing decoder using tensor

Broadband pulsed quadrature measurements with calorimeters

December 8, 2025
Author(s)
Ezad Shojaee, James R. van Meter, Karl Mayer, Scott Glancy, Emanuel Knill
A general one-dimensional quantum optical mode is described by a shape in the time or frequency domain. A fundamental problem is to measure a quadrature operator of such a mode. If the shape is narrow in frequency this can be done by pulsed homodyne

Competing Explanations for Spin Wave Resonances in L10(001) FePd Thin Films with Perpendicular Magnetic Anisotropy

December 2, 2025
Author(s)
Dingbin Huang, Jenae Shoup, Aaron Johnston-Peck, Deyuan Lyu, Jian-Ping Wang, Xiaojia Wang, Daniel Gopman
The Heisenberg exchange constant plays a crucial role in determining the switching behavior of magnetic nano-objects, along with the magnetic anisotropy, saturation magnetization, and Gilbert damping. This work seeks to estimate the exchange stiffness from

Mapping the phenotypic landscape of a transcriptional repressor using Deep Mutational Scanning and Growth-based Quantitative Sequencing

December 2, 2025
Author(s)
Zachary Jansen, Xuan Le, Qiyao Wei, Devon Kulhanek, Nina Alperovich, Olga Vasilyeva, Andrew Gilmour, David Ross, Ross Thyer
CymR is a TetR-family transcriptional repressor that recognizes a well-defined operator sequence in the promoter PcymRC. The native ligand cuminic acid and a series of structurally related aromatic acids can bind at an allosteric site and induce a

Selecting the complexity of the Moore-Penrose pseudoinverse for emission ghost imaging

December 2, 2025
Author(s)
Kevin Coakley, Huaiyu Chen-Mayer, Bruce Ravel, Daniel Josell, Nikolai Klimov, Daniel Hussey
We reconstruct X-ray fluorescence signals produced by synchrotron X-rays. In our method, we select the complexity of a Moore-Penrose pseudoinverse by a data-driven method, and study how systematic errors affect results for simulated data.

A comparative study of time on Mars with lunar and terrestrial clocks

December 1, 2025
Author(s)
Neil Ashby, Bijunath Patla
As space exploration extends into cislunar space and further towards Mars, understanding the relativistic effects on clocks on Mars—particularly in relation to multi-body gravitational influences—becomes increasingly important for accurate clock
