Prioritizing Cybersecurity Risk for Enterprise Risk Management

February 26, 2025
Author(s)
Stephen Quinn, Nahla Ivy, Matthew Barrett, Greg Witte, Robert Gardner
This document is the second in a series that supplements NIST Interagency Report (IR) 8286, Integrating Cybersecurity and Enterprise Risk Management (ERM). This series provides additional detail regarding the enterprise application of cybersecurity risk

Forensic Science Environmental Scan 2023

March 7, 2024
Author(s)
Henry Swofford
This environmental scan provides a broad view of the forensic science environment (as of 2023) and characterizes high-level historical and current issues and trends that might impact near and long-term decisions by forensic science research and standards

Tailoring the Magnetic Exchange Interaction in MnBi2Te4 Superlattices via the Intercalation of Ferromagnetic Layers

January 1, 2023
Author(s)
Peng Chen, Qi Yao, Junqi Xu, Qiang Sun, Alexander Grutter, Patrick Quarterman, Purnima P. Balakrishnan, Christy J. Kinane, Andrew J. Caruana, Sean Langridge, Ang Li, Barat Achinuq, Emily Heppell, Yuchen Ji, Shanshan Liu, Baoshan Cui, Jiuming Liu, Puyang Huang, Zhongkai Liu, Guoqiang Yu, Faxian Xiu, Thorsten Hesjedal, Jin Zou, Xiaodong Han, Haijun Zhang, Yumeng Yang, Xufeng Kou
The intrinsic magnetic topological insulator MnBi 2Te 4 (MBT) has provided a platform for the successful realization of exotic quantum phenomena. To broaden the horizons of MBT-based material systems, we intercalate ferromagnetic MnTe layers to construct

Deep Learning Image Analysis of Nanoplasmonic Sensors: Toward Medical Breath Monitoring

November 23, 2022
Author(s)
Yangyang Zhao, Boqun Dong, Kurt D. Benkstein, Lei Chen, Kristen L. Steffens, Stephen Semancik
Sensing biomarkers in exhaled breath offers a potentially portable, cost-effective, and noninvasive strategy for disease diagnosis screening and monitoring, while high sensitivity, wide sensing range, and target specificity are critical challenges. We

Developing multithreaded techniques and improved constraint handling for the tool CAgen

June 8, 2022
Author(s)
Michael Wagner, Manuel Leithner, Dimitris Simos, D. Richard Kuhn, Raghu N. Kacker
CAgen is a state-of-the-art combinatorial test generation tool that is known for its execution speed. In addition, it supports an extensive list of features such as constraint handling, higher-index arrays, and import and export of models/test sets in

Spatially-resolved bandgap and dielectric function in two-dimensional materials from Electron Energy Loss Spectroscopy

February 15, 2022
Author(s)
Abel Brokkelkamp, Jaco ter Hoeve, Isabel Postmes, Sabrya van Heijst, Luigi Maduro, Albert Davydov, Sergiy Krylyuk, Juan Rojo, Sonia Conesa Boj
The electronic properties of two-dimensional (2D) materials depend sensitively on the underlying atomic arrangement down to the monolayer level. Here we present a novel strategy for the determination of the band gap and complex dielectric function in 2D

Enhanced Magnetic Interaction by Face-Shared Hydride Anions in 6H-BaCrO 2 H

August 16, 2021
Author(s)
Kentaro Higashi, Masayuki Ochi, Yusuke Nambu, Takafumi Yamamoto, Taito Murakami, Naoya Yamashina, Cedric Tassel, Yuki Matsumoto, Hiroshi Takatsu, Craig Brown, Hiroshi Kageyama
Studies on magnetic oxyhydrides have been almost limited to perovskite-based lattices with corner-sharing octahedra with a M‒H‒M (M: transition metal) angle of θ 180 °. Using a high-pressure method, we prepared BaCrO 2H with a 6H-type hexagonal perovskite

Long-Range Magnetic Order in Hydroxide-Layer-Doped (Li 1-x-y Fe x Mn y OD)FeSe

March 11, 2020
Author(s)
Brandon Wilfong, Xiuquan Zhou, Huafei Zheng, Navneeth Babra, Craig Brown, Jeffrey W. Lynn, Keith M. Taddei, Johnpierre Paglione, Efrain E. Rodriguez
The (Li 1-xFe xOH)FeSe superconductor has been suspected to exhibit long-range magnetic ordering due to Fe substitution in the LiOH layer. However, no direct observation such as magnetic reflection from neutron diffraction has be reported. Here, we use a

Influence of optical system operation on stability of single tracks in selective laser melting

August 20, 2019
Author(s)
Ivan Zhirnov, Igor Yadroitsev, Brandon Lane, Sergey Mekhontsev, Steven Grantham, Ina Yadroitsava
Additive manufacturing (AM) technologies are increasingly being studied and introduced into the modern industry, but for wide applications there exists some "lack of confidence" about the quality of the parts produced by AM. This distrust has an objective
