Effect of network connectivity on behavior of synthetic Broborg Hillfort glasses

September 2, 2022
Author(s)
Jose Marcial, Maria Cicconi, Carolyn Pearce, Jaroslav Klouzek, James Neeway, Richard Pokorny, Miroslava Vernerova, John McCloy, Emily Nienhuis, Rolf Sjoblom, Jamie Weaver, Russell Hand, Pavel Hrma, Albert Kruger
There is wide industrial interest in developing robust models of long-term (>100years) glass durability. Archeological glass analogs, glasses of similar composition, and alteration conditions to those being tested for durability can be used to evaluate and

Network analysis approach to Likert-style surveys

September 2, 2022
Author(s)
Robert Dalka, Diana Sachmpazidi, Charles Henderson, Justyna Zwolak
Likert-style surveys are a widely used research instrument to assess respondents' preferences, beliefs, or experiences. In this paper, we propose and demonstrate how network analysis (NA) can be employed to model and evaluate the interconnectedness of

Overcoming Technological Barriers in Microfluidics: Leakage Testing

September 1, 2022
Author(s)
Vania Silverio, Suvajyoti Guha, Armelle Keiser, Rucha Natu, Darwin Reyes-Hernandez, Henne van Heeren, Nicolas Verplanck, Luke Herbertson
The miniaturization of laboratory procedures for Lab-on-Chip (LoC) devices and translation to various platforms such as single cell analysis or Organ-on-Chip (OoC) systems are revolutionizing the life sciences and biomedical fields. As a result

Visualizing Localized, Radiative Defects in GaAs Solar Cells

September 1, 2022
Author(s)
Behrang Hamadani, Margaret Stevens, Brianna Conrad, Matthew Lumb, Kenneth Schmieder
We have used a calibrated, wide-field hyperspectral imaging instrument to obtain absolute spectrally and spatially resolved photoluminescence images in high growth-rate, rear-junction GaAs solar cells from 300 K to 77 K. At the site of some localized

ALD deposited amorphous alumina coatings can slow glass alteration

August 31, 2022
Author(s)
Miriam Hiebert, Jamie Weaver, Thomas Lam, Nicole Little, Ethan Hyde, Edward Vicenzi, Ray A. Phaneuf
Atomic layer deposited (ALD) amorphous aluminum oxide and titanium oxide coatings have been investigated for use in reducing the rate of silicate glass alteration. Mass spectrometric analysis of leachate from elevated temperature aqueous immersion

NIST 2022 Language Recognition Evaluation Plan

August 31, 2022
Author(s)
Yooyoung Lee, Craig Greenberg, Lisa Mason, Elliot Singer
The 2022 NIST language recognition evaluation (LRE22) is the 9th cycle in an on-going language recognition evaluation series that began in 1996. The objectives of the evaluation series are (1) to advance technologies in language recognition with innovative

Design and Application of the Reconfigurable Mobile Manipulator Artifact (RMMA)

August 30, 2022
Author(s)
Roger V. Bostelman, Omar Aboul-Enein, Soocheol Yoon, Ya-Shian Li-Baboud
Robot arms onboard mobile bases, or mobile manipulators, are advancing and measurement of these systems is critical for robust safety and performance. As mobile manipulators flexibly fixture (i.e., do not fasten) to a worktable or object, they require

Simulated stress mitigation strategies in embedded 3D bioprinting

August 30, 2022
Author(s)
Leanne Friedrich, Ross Gunther, Jonathan Seppala
Extrusion-based 3D bioprinting is a powerful tool for fabricating complex cell-laden constructs. Embedded Ink Writing (EIW) is an extrusion-based printing technique wherein a nozzle embedded into a support bath writes continuous filaments. Because it

Why big data and compute are not necessarily the path to big materials science

August 30, 2022
Author(s)
Naohiro Fujinuma, Brian DeCost, Jason Hattrick-Simpers, Sam Lofland
Applied machine learning has rapidly spread throughout the physical sciences. In fact, machine learning-based data analysis and experimental decision-making have become commonplace. Here, we reflect on the ongoing shift in the conversation from proving

Advanced Communications Technologies Standards

August 29, 2022
Author(s)
Chris Greer, Robert B. Bohn, Tao Zhang
This report of the Advanced Communications Technologies Working Group of the Interagency Committee on Standards Policy (ICSP) provides an overview of Federal agency advanced communications technologies (ACT) standards activities and recommends standards

Cryogenic Decade-Passband Superconducting Integrated Diplexer

August 29, 2022
Author(s)
Akim Babenko, GREGOR LASSER, Nathan Flowers-Jacobs, Justus Brevik, Anna Fox, ZOYA POPOVIC, Paul Dresselhaus
We demonstrate a decade-passband superconducting diplexer operating from dc to 27 GHz, integrated in a niobium, Josephson-junction(JJ)-compatible process. Both low- and high-pass branches are singly-terminated 5-pole Butter-worth filters with a 2.5 GHz

Large Exotic Spin Torques in Antiferromagnetic Iron Rhodium

August 29, 2022
Author(s)
Jonathan Gibbons, Takaaki Dohi, Vivek Amin, Fei Xue, Haowen Ren, Hanu Arava, Hilal Saglam, Yuzi Liu, John Pearson, Nadya Mason, Amanda Petford-Long, Paul M. Haney, Soho Shim, Jun-wen Xu, Mark Stiles, Eric Fullerton, Andrew Kent, Shunsuke Fukami, Axel Hoffmann
Spin torque is a promising tool for driving magnetization dynamics for novel computing techniques. These torques can be easily produced by spin-orbit effects, but for most conventional spin source materials, a high degree of crystal symmetry limits the
