Nonlinear excitations in ferrites

November 22, 2022
Author(s)
Pavel Kabos
This book chapter describes the processes leading to nonlinear excitations in ferrites at high power levels. We start from equation of motion that include nonlinear terms leading to nonlinear processes. First and second order Suhl instabilities for

Digital Investigation Techniques: A NIST Scientific Foundation Review

November 21, 2022
Author(s)
James R. Lyle, Barbara Guttman, John Butler, Kelly Sauerwein, Christina Reed, Corrine Lloyd
This document is an assessment of the scientific foundations of digital forensics. We examined descriptions of digital investigation techniques from peer-reviewed sources, academic and classroom materials, technical guidance from professional organizations

Encouraging and Enabling Mutual Ownership in a RSE Community of Practice

November 21, 2022
Author(s)
Miranda Mundt, Jonathan Bisila, Jonathan E. Guyer, Daniel Howard, Daniel S. Katz, Reed Milewicz, Henry Schreiner, Joshua Teves, Chris Wiswell
The explosion of Research Software Engineers (RSEs) in the United States created the opportunity to form communities of practice (CoP), groups which share a passion for an activity and learn how to do it better as they interact regularly, specifically to

Vacancy-Driven Disorder and Elevated Dielectric Response in the Pyrochlore Pb 1.5 Nbd2^O 6.5

November 21, 2022
Author(s)
Uyen Dang, Jake O'Hara, Hayden Evans, Daniel Olds, Juan Chamorro, Daniel Hickox-Young, Geneva Laurita, Robin Macaluso
Lone-pair driven distortions are a hallmark of many technologically-important lead (Pb)-based materials. The role of Pb 2+ in polar perovskites is well understood and easily manipulated for applications in piezo- and ferroelectricity, but the control of

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 L. 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
