Author(s)
Michael Fagan, Katerina N. Megas, Jeffrey Marron, Kevin Gerard Brady, Barbara Bell Cuthill, Rebecca Herold, David Lemire, Noel Hoehn
Organizations will increasingly use Internet of Things (IoT) devices for the mission benefits they can offer, but care must be taken in the acquisition and implementation of IoT devices. This publication contains background and recommendations to help

IoT Device Cybersecurity Guidance for the Federal Government: IoT Device Cybersecurity Requirement Catalog

November 29, 2021
Author(s)
Katerina N. Megas, Michael Fagan, Jeffrey Marron, Kevin Gerard Brady, Barbara Bell Cuthill, Rebecca Herold, David Lemire, Noel Hoehn
This publication provides a catalog of internet of things (IoT) device cybersecurity capabilities (i.e., features and functions needed from a device to support security controls) and non-technical supporting capabilities (i.e., actions and support needed

Magnetic Structure Determination of High-Moment Rate-Earth-Based Laminates

November 29, 2021
Author(s)
D. Potashnikov, E. Caspi, A. Pesach, Q. Tao, J. Rosen, D. Sheptyakov, Hayden Evans, C. Ritter, Z. Salman, P. Bonfa, T. Ouisse, M. Barbier, O. Rivin, A. Keren
We report μSR on the 2D rare earth based parent magnets (Mo 2/3RE 1/3) 2AlC with RE = Nd, Gd, Tb, Dy, Ho and Er, and neutron diffraction on the series with RE ≠ Gd (a neutron absorber). By crossing information between the two techniques, we determine the

Report on High Energy Arc Fault Experiments: Experimental Results from Medium Voltage Electrical Enclosures

November 29, 2021

Gabriel Taylor, Anthony D. Putorti Jr., Scott Bareham, Edward Hnetkovsky, Kenneth Hamburger, Nicholas Melly, Mark Henry Salley, Christopher U. Brown, Wai Cheong Tam, Eric Link, Michael Selepak, Philip Deardorff, Kenneth Miller, Paul Clem, Byron Demosthenous, Austin Glover, Chris LaFleur, Raymond Martinez, Anthony Tanbakuchi
This report documents an experimental program designed to investigate High Energy Arcing Fault (HEAF) phenomena for medium voltage electrical switchgear containing aluminum conductors. This report covers full-scale laboratory experiments using

In-situ Monitoring of Protein Unfolding/Structural States under Cold High-Pressure Stress

November 26, 2021
Author(s)
Diana Gomes, Susana C. Marujo Teixeira, Juscelino Leao, Vladimir Razinkov, Wei Qi, Miguel Rodrigues, Christopher Roberts
Biopharmaceutical formulations may be compromised by freezing, which has been attributed to protein conformational changes at a low temperature, and adsorption to ice−liquid interfaces. However, direct measurements of unfolding/conformational changes in

Sintered powder oxidation variation as a function of build height for titanium alloy produced by electron beam powder-bed fusion

November 26, 2021
Author(s)
Nicholas Derimow, Alejandro Romero, Aldo Rubio, Cesar Terrazas, Francisco Medina, Ryan Wicker, Nik Hrabe
It is well-established that titanium alloy (Ti-6Al-4V) powder oxidizes during electron beam powder-bed fusion (PBF-EB) due to the high background temperatures resulting from layer preheating and sintering of the powder bed before melting. However, it is

BIPM comparison BIPM.RI(II)-K1.Gd-153 of activity measurements of the radionuclide 153Gd to include the 2020 result of the NIST (United States)

November 25, 2021
Author(s)
Denis E. Bergeron, Jeffrey T. Cessna, Ryan P. Fitzgerald, Lizbeth Laureano-Perez, Leticia Pibida, Carine Michotte, S Courte, M Nonis, R Coulon, S Judge
Since 1988, 3 laboratories have submitted 5 samples of 153Gd to the International Reference System (SIR) for activity comparison at the Bureau International des Poids et Mesures (BIPM), with comparison identifier BIPM.RI(II)- K1.Gd-153. Recently, the NIST

Imaging of Magnetic Excitations in Nanostructures with Microwave Near-Field Microscopy

November 25, 2021
Author(s)
Samuel Berweger, Robert Tyrrell-Ead, Houchen Chang, Mingzhong Wu, Hong Tang, Hans Nembach, Karl Stupic, Stephen E. Russek, Thomas Mitchell (Mitch) Wallis, Pavel Kabos
We present images of spin-wave excitations in a patterned yttrium iron garnet (YIG) thin film obtained by use of near-field microwave microscopy, which can achieve spatial resolution as high as 50 nm. Visualization of magnetic excitations is an enticing

NUScon: A community-driven platform for quantitative evaluation of nonuniform sampling in NMR

November 25, 2021
Author(s)
Yulia Pustovalova, Frank Delaglio, Darien Craft, Hari Arthanari, Ad Bax, Martin Billeter, Mark Bostock, Hesam Dashti, Flemming Hansen, Sven Hyberts, Bruce Johnson, Krzysztof Kazimierczuk, Hengfa Lu, Mark W. Maciejewski, Tomas Miljenovic, Mehdi Mobli, Daniel Nietlispach, Vladislav Orekhov, Robert Powers, Xiaobo Qu, Scott Robson, David Rovnyak, Gerhard Wagner, Jinfa Ying, Matthew Zambrello, Jeffrey C. Hoch, David Donoho, Adam D. Schuyler
Although the concepts of non-uniform sampling (NUS) and non-Fourier spectral reconstruction in multidimensional NMR began to emerge four decades ago (Bodenhausen and Ernst, 1981; Barna and Laue, 1987), it is only relatively recently that NUS has become

The science of the host-virus network

November 24, 2021
Author(s)
Gregory Albery, Daniel J. Becker, Liam Brierley, Cara Brook, Rebecca Christofferson, Lily Cohen, Tad Dallas, Evan Eskew, Anna Fagre, Maxwell Farrell, Emma Glennon, Sarah Guth, Maxwell Joseph, Nardus Mollentze, Ben Neely, Timothee Poisot, Angela Rasmussen, Sadie Ryan, Anna Siodin, Stephanie Seifert, Erin Sorrell, Colin Carlson
Better methods to predict and prevent the emergence of zoonotic viruses could support future efforts to reduce the risk of epidemics. We propose a network science framework for understanding and predicting human and animal susceptibility to viral
