Transit time corrections to the diffusion of atomic lattices

March 2, 2026
Author(s)
Alexander Pouliot, Gehrig Carlse, Eduardo Chomen Ramos, Thomas Vacheresse, Jaskaran Randhawa, Anantharaman Kumarakrishnan, Jacek Klos, Eite Tiesinga
We present transit time corrections for the diffusive decay of a ground state population grating formed by spatially periodic optical pumping. We present two classes of results, the first of which applies to a population grating with a Gaussian envelope

How "pro" are probiotics for wildlife species? Novel data, lack of evidence, and future directions

February 28, 2026
Author(s)
Sally Bornbusch, Piper Thacher, Marlitza Francisque, Alexandra DeCandia, Robyn Bortner, Della Garelle, Erin Kendrick, Michael Maslanka, Carly Muletz Wolz
Treatments that aim to purposefully manipulate host-associated microbiomes are now prevalent in human and animal medicine. Probiotics that contain live bacteria are purported to improve microbiome function and host health. Although research is advancing

Final report: Ecotoxicity of PFAS-Free Fire Fighting Foams: Fish and Aquatic Invertebrate Species ER20-1518

February 27, 2026
Author(s)
Edward Wirth, Marie DeLorenzo, Peter Key, Katy Chung, David Moore, Guilherme Lotufo, John Kucklick, Katherine Peter, Jessica Reiner
The Department of Defense (DoD) is actively engaging in research to identify fluorine free foams (F3) that do not contain per- and poly-fluorinated alkyl substances (PFAS) as replacements for traditional Aqueous Film Forming Foams (AFFF) products that

Metrics for spin-based computing

February 27, 2026
Author(s)
Advait Madhavan
Spin-based computing is emerging as a powerful approach for energy-efficient and high-performance computation. This review explores key advances in integrating magnetic and spintronic elements, from fundamental components like neurons, synapses, and

U.S. Election Expert Perspectives on End-to-End Verifiable Voting Systems

February 27, 2026
Author(s)
Julie Haney, Shanee Dawkins, Sandra Prettyman, Mary Theofanos, Kristen Greene, Kristin Koskey, Jody Jacobs
By using cryptographic techniques, end-to-end verifiable (E2EV) voting systems have been proposed as a way to increase voter trust and confidence in elections by providing the public with direct evidence of the integrity of election systems and outcomes

Nanodiscs formation process studied by contrast variation-SANS

February 26, 2026
Author(s)
Lea Poskin, Lionel Porcar, Sylvain Prevost, Ryan Murphy, Catherine Michaux, Anne Martel
Membrane proteins are essential for cellular communication and are frequently key targets for pharmaceutical intervention. However, their structural and dynamical characterization remains limited due to challenges associated with protein production and in

A Fabrication-Motivated Model for Improving Simulations of On-Wafer Transmission Lines

February 25, 2026
Author(s)
Florian Bergmann, Nicholas Jungwirth, Nicholas Derimow, Bryan Bosworth, Meagan Papac, Eric Marksz, Tomasz Karpisz, Jerome Cheron, Vincenzo St. George, Angela Stelson, Benjamin Jamroz, Christian Long, Nathan Orloff
Electromagnetic simulations are a ubiquitous tool for microwave engineers. We benchmark simulations by their agreement with experimental results. Transmission lines are an excellent test case because they have well-established measurement methodologies and

Certification of Standard Reference Material(R)s 3672a & 3673a: Organic Contaminants in Smokers' Urine (Frozen) & Organic Contaminants in Non-Smokers' Urine (Frozen)

February 25, 2026
Author(s)
Ashley Russell, Ben Blount, Julianne Botelho, Christina Brosius, Carolyn Burdette, Antonia Calafat, Johanna Camara, Jun Feng, Nathanael Heckert, Jennifer Hoguet, Kevin Huncik, Maria Morel Espinosa, Maria Ospina, Jared Ragland, Christopher Reese, Michael Rybak, Tiffany Seyler, Liza Valentin-Blasini, Lanqing Wang, Elena Wood, Baoyun Xia
Standard Reference Material (SRM) 3672a Organic Contaminants in Smokers' Urine (Frozen) and SRM 3673a Organic Contaminants in Non-Smokers' Urine (Frozen) are intended for use in evaluating analytical methods for the determination of selected naturally

Demonstration, validation, and application of hyperspectral microscopy for the collection of cyanobacterial spectral signatures

February 24, 2026
Author(s)
Natalie C. Hall, Adam Mumford, Aaron Goldfain, David Allen, Terry slonecker, Alisa Shtabnoy
Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins

Utilizing Pre-trained Language Models to Support Circular Design Decision-Making

February 23, 2026
Author(s)
Ananya Nandy, Ashley Hartwell, Katherine Morris
Circular practices (e.g., extending product/component life and recovering end-of-life products) can divert products from waste streams, creating alternative material sources and resilient production systems. Recently developed design guidelines and

Characterization of volcanic tuff pores pre- and post-underground nuclear detonation using ultra-small and small angle neutron scattering

February 21, 2026
Author(s)
Mei Ding, Rex Hjelm, Marilyn Hawley, Aviva Sussman, Scott Broome, Jennifer Wilson, John Barker, Erika Swanson, Chelsea Neil
The ability to accurately model the subsurface transport of radionuclides is fundamental to the remote detection and characterization of underground nuclear explosion (UNE) events. Developing more sophisticated transport models presents a significant
