A Peg-in-Hole Test and Analysis Method for Exoskeleton Evaluation

March 7, 2022
Author(s)
Ann Virts, Roger V. Bostelman, Soocheol Yoon, Ya-Shian Li-Baboud, Mili Shah
Work-place MusculoSkeletal Disorders (WMSD) continue to be the most significant source of industrial work force injuries. Exoskeletons are emerging as personal protective equipment (PPE) for sustained, repetitive, or intensive industrial tasks. This

Color-Temperature Dependence of Indoor Organic Photovoltaic Performance

March 5, 2022
Author(s)
Boya Zhang, Justin Bonner, Lakshmi Murthy, Thien Nguyen, Fong-Yi Cao, Yen-Ju Cheng, Behrang Hamadani, Julia Hsu
Organic materials are uniquely suited for indoor light energy harvesting because they absorb mostly in the visible spectrum and the absence of ultraviolet light minimizes their degradation. However, the performance of photovoltaic devices under indoor

Chapter: Structure and phase behavior of polyampholytes and polyzwitterions

March 4, 2022
Author(s)
Phillip Pickett, Yuanchi Ma, Vivek Prabhu, Michael Lueckheide, Nicholas Posey
Polyelectrolytes contain many units of charged moieties, often as either anionic or cationic. However, when a polymer comprises both anionic and cationic monomers, the result is a polyampholyte. Polyzwitterions are a type of polyampholyte that contain

Analysis of a silicon comb structure using an inverse Talbot-Lau neutron grating interferometer

March 3, 2022
Author(s)
Youngju Kim, Daeseung Kim, Jongyul Kim, Daniel Hussey, Mona Mirzaei, Dmitri Pushin, Charles W. Clark, Seung Lee
We describe an inverse Talbot-Lau neutron grating interferometer that provides an extended autocorrelation length range for quantitative dark-field imaging. To our knowledge, this is the first report of a Talbot-Lau neutron grating interferometer (nTLI)

Highly Versatile Strategy for the Production of Telechelic Polyolefins

March 3, 2022
Author(s)
Aaron Burkey, Danyon Fischbach, Kathryn L. Beers, Charlotte Wentz, Lawrence Sita
A general and versatile synthetic strategy for producing practical quantities of a wide range of phenyl-groupterminated hetero- and homotelechelic semicrystalline polyethenes and amorphous atactic and semicrystalline isotactic poly(α-olefins) is reported

Monte Carlo Augmented Channel Estimator

March 3, 2022
Author(s)
Alec Weiss, Atef Elsherbeni, Jeanne Quimby, Jake Rezac
We have developed a novel Monte Carlo-augmented channel estimator for millimeter-wave orthogonal frequency division multiplexing systems To better estimate and correct a transmitted orthogonal frequency division multiplexed signal by incorporating the

Open Media Forensics Challenge 2022 Evaluation Plan

March 3, 2022
Author(s)
Haiying Guan, Yooyoung Lee, Lukas Diduch
This document describes the system evaluation tasks supported by the Open Media Forensics Challenge (OpenMFC) 2022. The evaluation plan covers resources, task definitions, task conditions, file formats for system inputs and outputs, evaluation metrics

Specifying and Reasoning about CPS through the Lens of the NIST CPS Framework

March 3, 2022
Author(s)
Thanh Nguyen, Matthew Bundas, Tran Son, Marcello Balduccini, Kathleen Campbell Garwood, Edward Griffor
This paper introduces a formal definition of a Cyber-Physical System (CPS) in the spirit of the CPS Framework proposed by the National Institute of Standards and Technology (NIST). It shows that using this definition, various problems related to concerns

Computational Design of Helical Peptide Bundle Variants Spanning a Wide Range of Charge States

March 1, 2022
Author(s)
Jeffrey Fagan, Nairiti Sinha, rui gui, Darrin Pochan, Grethe Vestergaard Jensen, Jeffery Saven, matthew Langenstein, Rajkumar Misra, Christopher Kloxin, yan tang
Peptides can be computationally designed and engineered to achieve various functionalities and structures. Herein computational design was used to identify a set of 17 peptides having a wide range of putative charge states but the same tetrameric coiled

Life Cycle Environmental Impacts of Plastics: A Review

March 1, 2022
Author(s)
Paul Rikhter, Ilayda Dinc, Yirui Zhang, Ted Jiang, Bobby Miyashiro, Shelby Walsh, Ruoyu Wang, Yvonne Dinh, Sangwon Suh, Joshua D. Kneifel
Global production and consumption of plastics and its deposition in the environment are growing rapidly, while their life-cycle impacts to the environment are yet to be fully understood. This study reviews the existing literature with the goal of

Negative quasiprobabilities enhance phase estimation in quantum-optics experiment

March 1, 2022
Author(s)
Noah Lupu-Gladstein, Y. Batuhan Yilmaz, David Arvidsson-Shukur, Aharon Brodutch, Arthur Pang, Aephraim Steinberg, Nicole Halpern
Operator noncommutation, a hallmark of quantum theory, limits measurement precision, according to uncertainty principles. Wielded correctly, though, noncommutation can boost precision. A recent foundational result relates a metrological advantage with
