Performing Skin Microbiome Research: A Method to the Madness

March 1, 2027
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

Application of the Hybrid Satellite Network Cybersecurity Framework Profile: An Example Implementation of NIST IR 8441

February 23, 2024
Frederick R. Byers, Dan Mamula, Karri Meldorf, Joseph Brule, Rory Jennings, John Wiltberger, Eugene Craft, John Dombrowski, O'Ryan Lattin, Abdul Noor, Matt Yetto, Aliaksander Mamonau, Oksana Slivina, Jay Sharma, Dr. Kangmin Zheng
The space sector is transitioning towards Hybrid Satellite Networks (HSN), an aggregation of independently owned and operated terminals, antennas, satellites, payloads, or other components that comprise a satellite system. The elements of an HSN may have

Zeeman-resolved Autler-Townes splitting in Rydberg atoms with a tunable RF resonance and a single transition dipole moment

February 21, 2024
Noah Schlossberger, Drew Rotunno, Aly Artusio-Glimpse, Nik Prajapati, Samuel Berweger, Dangka Shylla, Matt Simons, Christopher L. Holloway
Applying a magnetic field as a method for tuning the frequency of Autler-Townes splitting for Rydberg electrometry has recently been demonstrated. In this Letter, we provide a theoretical understanding of Rydberg electromechanically-induced-transparency

Application of Electrical Standards to Torque Realization: A Device to Measure up to 1Nm

February 14, 2024
Zane Comden, Stephan Schlamminger, Frank Seifert, David B. Newell, Leon Chao
This paper describes the next generation prototype of the Electronic NIST Torque Realizer (ENTR) project. The first prototype version (ENTR-v1) has been able to realize low-range torques (on the order of 1×10-3 Nm) to uncertainties of less than 1000 parts

Digital PCR for the Characterization of Reference Materials

February 14, 2024
Megan Cleveland, Hua-Jun He, Mojca Milavec, Young-Kyung Bae, Peter Vallone, Jim Huggett
Well characterized reference materials are essential to ensuring the harmonization and accuracy of nucleic acid-based tests (such as qPCR); digital PCR (dPCR) can measure the absolute concentration of a specific nucleic acid sequence in a background of non

Advancing Measurement Science for Microelectronics: CHIPS R&D Metrology Program

February 13, 2024
Marla L. Dowell, Hannah Brown, Gretchen Greene, Paul D. Hale, Brian Hoskins, Sarah Hughes, Bob R. Keller, R Joseph Kline, June W. Lau, Jeff Shainline
The CHIPS and Science Act of 2022 called for NIST to "carry out a microelectronics research program to enable advances and breakthroughs....that will accelerate the underlying R&D for metrology of next-generation microelectronics and ensure the

Overview of the NTCIR-17 FairWeb-1 Task

February 13, 2024
Sijie Tao, Nuo Chen, Tetsuya Sakai, Zhumin Chu, Hiromi Arai, Ian Soboroff, Nicola Ferro, Maria Maistro
This paper provides an overview of the NTCIR-17 FairWeb-1 Task. FairWeb-1 is an English web search task which seeks more than an ad-hoc web search task. Our task considers not only document relevance but also group fairness. We designed three types of

The Impact of Material Composition on Ignitability and Fire Growth. Volume 1: Full-Scale Burning Behavior of Combustible Solids Commonly Found in Nuclear Power Plants

February 13, 2024
Isaac Leventon, Michael Heck, Kevin B. McGrattan, Matthew Bundy, Rick D. Davis
This report provides an overview of quantitative measurement data and visual observations obtained from a series of 52 full-scale fire growth experiments conducted on 16 unique combustible solids including: natural and synthetic polymers, copolymers

Continuum of magnetic excitations in the Kitaev honeycomb iridate D3LiIr2O6

February 12, 2024
Thomas Halloran, Yishu Wang, Kemp Plumb, M. B. Stone, Barry Winn, M. K. Graves-Brook, Jose Rodriguez Rivera, Yiming Qiu, Prashant Chauhan, N. Armitage, Tomohiro Takayama, Hidenori Takagi, Collin L. Broholm
Inelastic neutron scattering (INS) measurements of powder D3(7Li)(193Ir)2O6 reveal low energy magnetic excitations with a scattering cross section that is featureless versus |Q| and consistent with a Kitaev spin-liquid (KSL) state. The magnetic nature of

Establishing a framework for best practices for quality assurance and quality control in untargeted metabolomics

February 12, 2024
Tracey Schock, Jonathan Mosley, Chris Beecher, Warwick Dunn, Julia Kuligowski, Matthew Lewis, Georgios Theodoridis, Candice Ulmer, Dajana Vuckovic, Ian Wilson, Krista Zanetti
Background: Quality assurance (QA) and quality control (QC) practices are key tenets that facilitate study and data quality across all applications of untargeted metabolomics. Such important practices will strengthen this field and accelerate its success

High-Performance Computing Security Architecture, Threat Analysis, and Security Posture

February 9, 2024
Yang Guo, Ramaswamy Chandramouli, Lowell Wofford, Rickey Gregg, Gary Key, Antwan Clark, Catherine Hinton, Andrew Prout, Albert Reuther, Ryan Adamson, Aron Warren, Purushotham Bangalore, Erik Deumens, Csilla Farkas
Security is essential component of high-performance computing (HPC). HPC systems often differ based on the evolution of their system designs, the applications they run, and the missions they support. An HPC system may also have its own unique security

ToF-SIMS Analysis of Ultrathin Films and Their Fragmentation Patterns

February 8, 2024
Shin Muramoto, Daniel Graham, David Castner
Organic thin films are of great interest due to their intriguing interfacial and functional properties, especially for device applications such as thin-film transistors and sensors. As their thickness approaches single nanometer thickness, characterization

NIST Research Data Framework (RDaF): Version 2.0

February 7, 2024
Robert Hanisch, Debra L. Kaiser, Alda Yuan, Andrea Medina-Smith, Bonnie C Carroll, Eva Campo
The NIST Research Data Framework (RDaF) is a multifaceted and customizable tool that aims to help shape the future of open data access and research data management (RDM). The RDaF will allow organizations and individual researchers to develop their own RDM
