NB-IoT Devices in Reverberation Chambers: A Comprehensive Uncertainty Analysis

February 17, 2021
Author(s)
Catherine Remley, Anouk Hubrechsen, Robert Jones, Robert Horansky, Vincent Neylon, Laurens A. Bronckers
New protocols related to internet-of-things applications may introduce previously unnoticed measurement effects in reverberation chambers due to the narrowband nature of these protocols. Such technologies also require less loading to meet the coherence

A Data-Driven Framework for Team Formation for Maintenance Tasks

February 16, 2021
Author(s)
Maya Reslan, Emily Hastings, Michael Brundage, Thurston Sexton
Even as maintenance evolves with new technologies, it is still a heavily human-driven domain; multiple steps in the maintenance workflow still require human expertise and intervention. Various maintenance activities require multiple maintainers, all with

Controlling Bicontinuous Structures through Solvent Segregation Driven Gel

February 16, 2021
Author(s)
Yuyin Xi, Juscelino Leao, Qiang Ye, Ronald S. Lankone, Li Piin Sung, Yun Liu
The past decade has seen increased research interests in studying bicontinuous structures formed by the colloidal self-assembly due to their many useful applications. A new type of colloidal gel, solvent segregation driven gel (SeedGel), has been recently

Adsorption of Non-Ionic Surfactant and Monoclonal Antibody on Siliconized Surface Studied by Neutron Reflectometry

February 15, 2021
Author(s)
Zhenhuan Zhang, Ann M. Woys, Kunlun Hong, Christoph Grapentin, Tarik A. Khan, Isidro E. Zarraga, Norman J. Wagner, Yun Liu
The adsorption of monoclonal antibodies (mAbs) on hydrophobic surfaces is known to cause protein aggregation and degradation. Therefore, surfactants, such as Poloxamer 188, are widely used in therapeutic formulations to stabilize mAbs and protect mAbs from

On Deep Reinforcement Learning Security for Industrial Internet of Things

February 15, 2021
Author(s)
Xing Liu, Wei Yu, Fan Liang, David W. Griffith, Nada T. Golmie
Industrial Internet of Things (IIoT), also known as Industry 4.0, empowers manufacturing and production processes by leveraging automation and Internet of Things (IoT) technologies. In IIoT, the information communication technologies enabled by IoT could

Optimal Cybersecurity Investments for SIS Model

February 15, 2021
Author(s)
Van Sy Mai, Richard La, Abdella Battou
We study the problem of minimizing the (time) average security costs in large systems comprising many interdependent subsystems, where the state evolution is captured by a susceptible-infected-susceptible (SIS) model. The security costs reflect security

Substrate-mediated hyperbolic phonon polaritons in MoO3

February 15, 2021
Author(s)
Jeffrey Schwartz, Son T. Le, Sergiy Krylyuk, Curt A. Richter, Albert Davydov, Andrea Centrone
Hyperbolic phonon polaritons (HPhPs) are hybrid excitations of light and coherent charge oscillations that exist in strongly optically anisotropic, two-dimensional materials (e.g., MoO3). These polaritons propagate through the material's volume with long

Micromechanical Behaviorof Multilayered Ti/Nb Composites Processed by Accumulative Roll Bonding: An in-situ Synchrotron X-ray Diffraction Investigation

February 14, 2021
Author(s)
S. Jiang, R. L. Peng, Z. Hegedus, Thomas Gnaupel-Herold, J. J. Moverare, U. Lienert, F. Fang, X. Zhao, L. Zuo, N. Jia
Ti/Nb multilayered composites were fabricated by accumulative roll bonding (ARB). With increasing ARB cycles, shear bands become predominant in the continuously strengthened composites. The correlation between micromechanical behavior and mechanical

Note: A Bitter-type electromagnet for complex atomic trapping and manipulation

February 12, 2021
Author(s)
Jacob L. Siegel, Daniel Barker, James A. Fedchak, Julia Scherschligt, Stephen Eckel
We create a pair of symmetric Bitter-type electromagnet assemblies capable of producing multiple field configurations including uniform magnetic fields, spherical quadruple traps, or Ioffe-Pritchard magnetic bottles. Unlike other designs, our coil allows

Why Polymer Glasses with Enhanced Sub-nanosecond Relaxation are Tougher

February 12, 2021
Author(s)
Christopher Soles, Adam B. Burns, Kanae N. Ito, Jack Douglas, Robert Dimeo, Madhu Sudan Tyagi, Jingsheng Wu, Albert F. Yee, Yueh-Ting Shih, Liping Huang
This manuscript explores the connection between the fast relaxation processes in a polymer glass and essential trends in the mechanical toughness, a non-linear mechanical property that is of practical interest for engineering polymers with high impact

Foundational PNT Profile: Applying the Cyber Security Framework for the Responsible Use of Positioning, Navigation, and Timing (PNT) Services

February 11, 2021
Author(s)
Jim McCarthy, Karen Reczek, Michael Bartock, Ya-Shian Li-Baboud, Suzanne Lightman, Arthur Scholz, Theresa Suloway, Doug Northrip, Joesph Brule
The national and economic security of the United States (US) is dependent upon the reliable functioning of critical infrastructure. Positioning, Navigation and Timing (PNT) services are widely deployed throughout the critical infrastructure. A disruption

Key Practices in Cyber Supply Chain Risk Management: Observations from Industry

February 11, 2021
Author(s)
Jon M. Boyens, Celia Paulsen, Nadya Bartol, Kris Winkler, James Gimbi
In today's highly connected, inter-dependent world, all organizations rely on others for critical products and services. However, the reality of globalization, while providing many benefits, has resulted in a world where organizations no longer fully

Voices of First Responders - Applying Human Factors and Ergonomics Knowledge to Improve the Usability of Public Safety Communications Technology: Findings from User-Centered Interviews, Phase 1, Volume 5

February 11, 2021
Author(s)
Yee-Yin Choong, Gavriel Salvendy
With the newly created Nationwide Public Safety Broadband Network (NPSBN), the public safety community is in the process of supplementing the use of land mobile radios with a technology ecosystem that will include a variety of new and improved
