Author(s)
Heidi H. Kong, Bj?rn Andersson, Thomas Clavel, John E. Common, Scott Jackson, Nathanael David Olson, Julia Segre, Claudia Traidl-Hoffman
Growing interest in microbial contributions to human health and disease has increasingly led investigators to examine the microbiome in both healthy skin and cutaneous disorders, including acne, psoriasis, and atopic dermatitis. The need for common

Chemical characteristics of indoor aerosol particles and surface films

July 8, 2024
Author(s)
Rachel O'Brien, Cate Shirilla, Amy Hrdina, Emily Legaard, Kathryn Mayer, Marina Vance, Dustin Poppendieck, Delphine Farmer
Indoor surfaces and the films on them play important roles in indoor air quality due to the high surface area to volume ratios in our homes. The chemical complexity of these films can be large, and this can increase after film formation as the chemicals in

Marina Vance, Liora Mael, Sofie Schwink, Kathryn Mayer, Thomas Dunnington, Maximilian Schmid, Nicholas Gotlib, Andrew Martin, Dustin Poppendieck, Delphine Farmer
We studied the impacts of aging and relative humidity on simulated wildfire smoke in a test house during the Chemical Assessments of Surfaces and Air (CASA) study. We injected fresh and ozone-aged biomass burning smoke into the test house during times of

AI Use Taxonomy: A Human-Centered Approach

March 26, 2024
Author(s)
Mary Frances Theofanos, Yee-Yin Choong, Theodore Jensen
As artificial intelligence (AI) systems continue to be developed, humans will increasingly participate in human-AI interactions. Humans interact with AI systems to achieve particular goals. To ensure that AI systems contribute positively to human-AI

Certification Approaches for Weigh-In-Motion Systems in Law Enforcement Applications

March 26, 2024
Author(s)
Katrice Lippa, Jan Konijnenburg, Loren Minnich, Tanvi Pandya, James Willis
Every day, overweight and excessively heavy vehicles cause damage to roads, bridges, and other vehicle-based infrastructure. To protect this vital transportation infrastructure for the U.S., states have imposed weight limits for commercial and fleet

Bilayer crystals of trapped ions for quantum information processing

March 25, 2024
Author(s)
Samarth Hawalder, Prakriti Shahi, Allison Carter, Ana Maria Rey, John J. Bollinger, Athreya Shankar
Trapped ion systems are a leading platform for quantum information processing, but they are currently limited to 1D and 2D arrays, which imposes restrictions on both their scalability and their range of applications. Here, we propose a path to overcome

A case study of multi-modal, multi-institutional data management for the combinatorial materials science community

March 22, 2024
Author(s)
Sarah Allec, Eric Muckley, Nathan Johnson, Christopher Borg, Dylan Kirsch, Joshua B. Martin, Ichiro Takeuchi, Andrew Lee, James Saal, Logan Ward, Apruva Mehta
Although the convergence of high-performance computing, automation, and machine learning has significantly altered the materials design timeline, transformative advances in functional materials and acceleration of their design will require addressing the

NIST Scientific Integrity Program Annual Report

March 22, 2024
Author(s)
Anne Andrews, Justyna Zwolak
This report summarizes the findings of the National Institute of Standards and Technology Scientific Integrity Program assessment of the program for the period between 1 June 2022 and 30 September 2023. It provides an assessment of the current state of the

Measurement-driven Langevin modeling of superparamagnetic tunnel junctions

March 19, 2024
Author(s)
Liam Pocher, Temitayo Adeyeye, Sidra Gibeault, Philippe Talatchian, Ursula Ebels, Daniel Lathrop, Jabez J. McClelland, Mark Stiles, Advait Madhavan, Matthew Daniels
Superparamagnetic tunnel junctions are important devices for a range of emerging technologies, but most existing compact models capture only their mean switching rates. Capturing qualitatively accurate analog dynamics of these devices will be important as

Results of an Interlaboratory Study on the Working Curve in Vat Photopolymerization

March 18, 2024
Author(s)
Thomas Kolibaba, Jason Killgore, Benjamin Caplins, Callie Higgins, Uwe Arp, C Cameron Miller, Yuqin Zong
The working curve informs resin properties and print parameters for stereolithography, digital light processing, and other photopolymer additive manufacturing (PAM) technologies. First demonstrated in 1992, the working curve measurement of cure depth vs

National Institute on Drug Abuse Clinical Trials Network Meeting Report: Managing Patients Exposed to Xylazine-Adulterated Opioids in Emergency, Hospital and Addiction Care Settings

March 16, 2024
