Phase-transition-induced Thermal Hysteresis in Type-II Weyl Semimetals MoTe2 and Mo(1-x)W(x)Te2

November 19, 2022
Author(s)
Md Sabbir Akhanda, Sergiy Krylyuk, Diane Dickie, Albert Davydov, Fei Han, Mingda Li, Mona Zebarjadi
The resistivity versus temperature measurement is commonly used for identifying temperature-induced phase change and the resulting hysteresis loop. While the resistance is influenced by both the density of states and the carrier lifetimes, the Seebeck

Efficient Parameter Exploration of Simulation Studies

November 18, 2022
Author(s)
Megan Olsen, M S Raunak
Simulation is a useful and effective way to analyze and study complex, real-world systems. It allows researchers, practitioners, and decision makers to make sense of the inner working of a system that involves many factors often resulting in some sort of

Optical Atomic Clock aboard an Earth-orbiting Space Station (OACESS): Enhancing searches for physics beyond the standard model in space

November 18, 2022
Author(s)
Vladimir Schkolnik, Dmitry Budker, Oliver Farttman, Victor Flambaum, Leo Hollberg, Tigran Kalaydzhyan, Shimon Kolkowitz, Markus Krutzik, Andrew Ludlow, Nathan R. Newbury, Christopher Pyrlik, Laura Sinclair, Yevgeny Stadnik, Ingmari Tietje, Jun Ye, Jason Williams
We present a concept for a high-precision optical atomic clock (OAC) operating on an Earth-orbiting space station. This pathfinder science mission will compare the space-based OAC with one or more ultra-stable terrestrial OACs to search for space-time

Guide to a Secure Enterprise Network Landscape

November 17, 2022
Author(s)
Ramaswamy Chandramouli
Access to multiple cloud services, the geographic spread of enterprise Information Technology (IT) resources (including multiple data centers), and the emergence of microservices-based applications (as opposed to monolithic ones) have significantly altered

Using Business Impact Analysis to Inform Risk Prioritization and Response

November 17, 2022
Author(s)
Stephen Quinn, Nahla Ivy, Julie Chua, Matthew Barrett, Greg Witte, Larry Feldman, Daniel Topper, Robert Gardner
While business impact analysis (BIA) has historically been used to determine availability requirements for business continuity, the process can be extended to provide a broad understanding of the potential impacts of any type of loss on the enterprise

Engineering Trustworthy Secure Systems

November 16, 2022
Author(s)
Ronald S. Ross, Mark Winstead, Michael McEvilley
This publication describes a basis for establishing principles, concepts, activities, and tasks for engineering trustworthy secure systems. Such principles, concepts, activities, and tasks can be effectively applied within systems engineering efforts to

GLFF: Global and Local Feature Fusion for Face Forgery Detection

November 16, 2022
Author(s)

Haiying Guan, Yan Ju, Shan Jia, Jialing Cai, Siwei Lyu

With the rapid development of the deep generative models (such as Generative Adversarial Networks and Auto-encoders), AI-synthesized images of human face are now of such high qualities that humans can hardly distinguish them from pristine ones. Although

Life History, Contaminant and Histopathologic Assessment of Beluga Whales, Delphinapterus leucas, Harvested for Subsistence in Cook Inlet, Alaska, 1989-2005

November 16, 2022
Author(s)
Kathy Burek-Huntington, Kim Shelden, Kim Goetz, Barbara Mahoney, Dan Vos, Jessica Reiner, Jennifer Hoguet, Greg O'Corry-Crowe
Throughout the State of Alaska, ranging from the eastern Beaufort Sea to Bristol Bay, and within the boundaries of Cook Inlet, belugas are an important subsistence resource for Native communities. Cook Inlet belugas (CIBs, Delphinapterus leucas) are

An IEEE Standard for the Evaluation of Wireless Networks for Industrial Automation

November 15, 2022
Author(s)
Rick Candell, Mohamed Hany, Javier Perez-Ramirez, Juan Conchas
Adoption of wireless systems for use in industrial scenarios is increasing, although slowly, in process control and discrete manufacturing. In particular, factories must make the leap towards wireless networks as a central form of communications to enable

Measuring the Common Vulnerability Scoring System Base Score Equation

November 15, 2022
Author(s)
Peter Mell, Jonathan Spring, Dave Dugal, Srividya Ananthakrishna, Francesco Casotto, Troy Fridley, Christopher Ganas, Arkadeep Kundu, Phillip Nordwall, Vijayamurugan Pushpanathan, Daniel Sommerfeld, Matt Tesauro, Christopher Turner
This work evaluates the validity of the Common Vulnerability Scoring System (CVSS) Version 3 ''base score'' equation in capturing the expert opinion of its maintainers. CVSS is a widely used industry standard for rating the severity of information

Advanced Persistent Threat Detection using Data Provenance and Metric Learning

November 14, 2022
Author(s)
Khandakar Ashrafi Akbar, Yigong Wang, Gbadebo Ayoade, Yang Gao, Anoop Singhal, Latifur Khan, Bhavani Thuraisingham, kangkook Jee
Advanced persistent threats (APT) have increased in recent times as a result of the rise in interest by nation states and sophisticated corporations to obtain high-profile information. Typically, APT attacks are more challenging to detect since they

Hyperspectral Imaging of Localized, Optically-Active Defects in GaAs Solar Cells

November 14, 2022
Author(s)
Behrang Hamadani, Margaret Stevens, Brianna Conrad, Matthew Lumb, Eric Armour, Kenneth Schmieder
A novel hyperspectral imaging instrument with dual electroluminescence and photoluminescence capability was used to image and analyze localized radiative defects in rear-junction GaAs solar cells grown at 1 µm/min. The absolute photon emission rates were

Investigating the electronic structure of high explosives with x-ray Raman spectroscopy

November 14, 2022
Author(s)
Oscar Ariel Paredes Mellone, Dimosthenis Sokaras, Trevor Willey, Michael Nielsen, John Vinson
We investigate the sensitivity and potential of a synergistic experiment-theory X-ray Raman spectroscopy (XRS) methodology on revealing and following the static and dynamic electronic structure of high explosive molecular materials. We show that advanced
