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
