Chemically Induced Magnetic Dead Shells in Superparamagnetic Ni Nanoparticles Deduced from Polarized Small-Angle Neutron Scattering

July 17, 2022
Author(s)
Bhaskar Das, Joseph Batley, Kathryn L. Krycka, Julie A. Borchers, Patrick Quarterman, Caroline Korostynski, My Nguyen, Ishita Kamboj, Eray Aydil, Chris Leighton
Advances in synthesis and characterization of colloidal magnetic nanoparticles (NPs) have yielded great gains in the understanding of their complex magnetic behavior, with implications for numerous applications. Recent work using Ni NPs as a model soft

Polymorphic variant Asp239Tyr of human DNA glycosylase NTHL1 is inactive for removal of a variety of oxidatively-induced DNA base lesions from genomic DNA

July 16, 2022
Author(s)
Melis Kant, Victoria Quintana, Erdem Coskun, Pawel Jaruga, R. Stephen Lloyd, Joann Sweasy, Miral M. Dizdar
Base excision repair is the major pathway for the repair of oxidatively-induced DNA damage with DNA glycosylases removing modified DNA bases in the first step. Among them, human NTHL1 is specific for excision of several pyrimidine- and purine-derived

Comparison of two multiplexed portable cold atom vacuum standards

July 15, 2022
Author(s)
Lucas Ehinger, Bishnu Acharya, Daniel Barker, James A. Fedchak, Julia Scherschligt, Eite Tiesinga, Stephen Eckel
We compare the vacuum measured by two portable cold atom vacuum standards (pCAVS) based on ultracold $^7$Li atoms. Our pCAVS devices share the same laser system and measure the vacuum concurrently. The two pCAVS together detected a leak with a rate on the

Gate resistance thermometry: An electrical thermal characterization technique

July 15, 2022
Author(s)
Georges Pavlidis, Brian Foley, Samuel Graham
Gate Resistance Thermometry (GRT) is a potential reliable technique to determine the average temperature of the gate metal in GaN transistors. In contrast to other electrical techniques that average the temperature across different areas of the active

Technical Framework for High Quality New Approach Methodologies (NAMs)

July 15, 2022
Author(s)
Elijah Petersen, John T. Elliott, John Gordon, Nicole Kleinstreuer, Emily Reinke, Matthias Roesslein, Blaza Toman
New approach methodologies (NAMs) are in vitro, in chemico, and computational approaches that can potentially be used to reduce animal testing. For NAMs that require laboratory experiments, it is critical that they provide consistent and reliable results

Analyzing Data Privacy for Edge Systems

July 14, 2022
Author(s)
Olivera Kotevska, Jordan Johnson, A. Gilad Kusne
Internet-of-Things (IoT)-based streaming applications are all around us. Currently, we are transitioning from IoT processing being performed on the cloud to the edge. While moving to the edge provides significant networking efficiency benefits, IoT edge

Why Indoor Chemistry Matters: A National Academies Consensus Report

July 14, 2022
Author(s)
Rima Habre, Megan Harris, David Dorman, Jonathan Abbatt, William Bahnfleth, Ellison Carter, Delphine Farmer, Gillian Gawne-Mittelstaedt, Allen Goldstein, Vicki Grassian, Glenn Morrison, Jordan Peccia, Kimberly Prather, Dustin Poppendieck, Manabu Shiraiwa, Heather Stapleton, Meredith Williams

Crystallize it before it diffuses: Thin -film growth of the phosphorus-rich semiconductor CuP2

July 13, 2022
Author(s)
Feng Yi, David A. LaVan, Andrea Crovetto, Danny Kojda, Karen Heinselman, Klaus Habicht, Thomas Unold, Andriy Zakutayev
Numerous phosphorus-rich metal phosphides containing both P-P bonds and metal-P bonds are known from the solid state chemistry literature. Yet, very little is known about the thin- film synthesizability and properties of even the simplest binary compounds

The Expanding Role of National Metrology Institutes in the Quantum Era

July 12, 2022
Author(s)
Alexander Tzalenchuk, Nicolas Spethmann, Tim Prior, Jay H. Hendricks, Yijie Pan, Vladimir Bubanja, Guilherme Temporao, Dai-Hyuk Yu, Damir Ilic, Barbara L. Goldstein
Now that all base units are defined in terms of fundamental constants and can thus — at least in principle — be realized anytime and anywhere, rather than through a measurement chain leading back to unique physical artefacts, who holds the traceability

Discovery of digital forensic dataset characteristics with CASE-Corpora

July 11, 2022
Author(s)
Alexander Nelson
The digital forensics community has generated training and reference data over the course of decades. However, significant challenges persist today in the usage pipeline for that data, from research problem formulation, through discovery of applicable

Human Preferences as dueling Bandits

July 11, 2022
Author(s)
Xinyi Yan, Chengxi Luo, Charles Clarke, Nick Craswell, Ellen M. Voorhees, Pablo Castells
The dramatic improvements in core information retrieval tasks engendered by neural rankers create a need for novel evaluation methods. If every ranker returns highly relevant items in the top ranks, it becomes difficult to recognize meaningful differences

Inclusive Language in NIST Technical Series Publications

July 11, 2022
Author(s)
Kathryn Miller
The National Institute of Standards and Technology (NIST) Research Library occupies the unique position of serving NIST both as publisher of the NIST Technical Series, and in an archival capacity, responsible for collecting and preserving copies of NIST's
