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

Assessing Composite Structure in Metal-Organic Framework-Polymer Mixed-Matrix Membranes

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

DC to GHz measurements of a near-ideal 2D material: P+ monolayers

March 8, 2024
Author(s)
Neil M. Zimmerman, Antonio Levy, Pradeep Namboodiri, Joshua M. Pomeroy, Xiqiao Wang, Joseph Fox, Richard M. Silver
P+ monolayers in Si are of great scientific and technological interest, both intrinsically as a material in the "ideal vacuum" of crystalline Si, and because they are showing great promise as qubits of electron and nuclear spin. The GHz complex

An Open Source Iris Segmentation Algorithm for Non-ideal Images

March 7, 2024
Author(s)
George W. Quinn
This document describes a new approach to localizing the iris boundaries in non-ideal iris images. The proposed algorithm starts by applying a series of morphological operations to enhance the salience of the iris boundaries while mitigating the impact of

Comparison of N-glycopeptide to released N-glycan abundances and the influence of glycopeptide mass and charge state on N-linked glycosylation of IgG antibodies

March 7, 2024
Author(s)
Concepcion Remoroza, Meghan Burke Harris, Tytus Mak, Sergey Sheetlin, Yuri Mirokhin, Zachary Goecker, Brian T. Cooper, Mark Lowenthal, Xiaoyu (Sara) Yang, Guanghui Wang, Dmitrii V. Tchekhovskoi, Stephen E. Stein
We report the comparison of mass-spectral-based abundances of tryptic glycopeptides to fluorescence abundances of released labeled glycans and the effects of mass and charge state and in-source fragmentation on glycopeptide abundances. The primary

Forensic Science Environmental Scan 2023

March 7, 2024
Author(s)
Henry Swofford
This environmental scan provides a broad view of the forensic science environment (as of 2023) and characterizes high-level historical and current issues and trends that might impact near and long-term decisions by forensic science research and standards

Initial Framework to Design Lifeline Infrastructure for Post-Earthquake Functional Recovery Volume 1
