Performing Skin Microbiome Research: A Method to the Madness

March 1, 2027
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

Impacts of Aging and Relative Humidity on Biomass Burning Smoke in an Indoor Environment

July 8, 2024
Author(s)
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

Entangled photon pair generation in an integrated SiC platform

Anouar Rahmouni, Lijun Ma, Ruixuan Wang, Jingwei Li, Xiao Tang, Thomas Gerrits, Qing Li, Oliver T. Slattery
Entanglement plays a vital role in quantum information processing. Owing to its unique material properties, silicon carbide recently emerged as a promising candidate for the scalable implementation of advanced quantum information processing capabilities

Rydberg states of alkali atoms in atomic vapor as SI-traceable field probes and communications receivers

May 8, 2024
Author(s)
Noah Schlossberger, Nik Prajapati, Samuel Berweger, Andrew Rotunno, Aly Artusio-Glimpse, Abrar Sheikh, Eric Norrgard, Christopher L. Holloway, Stephen Eckel
Rydberg states of alkali atoms are highly sensitive to electric fields because their electron wavefunction has a large spatial extent, leading to large polarizabilities for static fields and large transition dipole moments for time-varying fields

Rydberg states of alkali atoms in atomic vapor as SI-traceable field probes and communications receivers

Rydberg states of alkali atoms are highly sensitive to electric fields because their electron wavefunction has a large spatial extent, leading to large polarizabilities for static fields and large transition dipole moments for time-varying fields

Single-electron states of phosphorus-atom arrays in silicon

May 8, 2024
Author(s)
Maicol Ochoa, Keyi Liu, Michal Zielinski, Garnett W. Bryant
We characterize the single-electron energies and the wavefunction structure of arrays with two, three, and four phosphorus atoms in silicon by implementing atomistic tight-binding calculations and analyzing wavefunction overlaps to identify the single

Usability for Poll Workers: A Voting System Usability Test Protocol

May 8, 2024
Author(s)
Dana Chisnell, Sharon J. Laskowski, Karen Bachmann, Svetlana Z. Lowry
In this paper, we discuss our efforts to develop a repeatable test protocol for assessing usability for poll workers – temporary election officials who ensure secure and private voting in voting places. The research described in this paper is part of a

Access Control on NoSQL Databases

May 7, 2024
Author(s)
Vincent C. Hu
NoSQL database systems and data stores often outperform traditional RDBMS in various aspects, such as data analysis efficiency, system performance, ease of deployment, flexibility/scalability of data management, and users' availability. However, with an

Metropolitan-scale Entanglement Distribution, with Co-existing Quantum and Classical Signals in a single fiber

Henry Swofford, Steven Lund, Hariharan K. Iyer, John Butler, Johannes A. Soons, Robert M. Thompson, Vincent Desiderio, JP Jones, Robert Ramotowski
In recent years, there has been discussion and controversy relating to the treatment of inconclusive decisions in forensic feature comparison disciplines when considering the reliability of examination methods and results. In this article, we offer a brief

Collection Methods for High-SNR I/Q Recordings of FDD LTE User Equipment Emissions

May 3, 2024
Author(s)
Keith Forsyth, Aric Sanders, Dan Kuester, Adam Wunderlich
This report documents collection methods for high signal-to-noise ratio (SNR) in-phase and quadrature (I/Q) radio frequency (RF) recordings of long-term evolution (LTE) uplink emissions from a commercial-off-the-shelf (COTS) handset in a fully conducted
