Forensic Iris: A Review, 2022

July 18, 2022
Author(s)
James Matey, George W. Quinn, Patrick J. Grother
John Daugman correctly summarized the state of forensic iris recognition circa 2006 for the book Forensic Human Identification: an Introduction [1]: Iris recognition has limited forensic value, because (unlike fingerprints or DNA, for example) (1) iris

Implementation of a Binary Neural Network on a Passive Array of Magnetic Tunnel Junctions

July 18, 2022
Author(s)
Jonathan Goodwill, Nitin Prasad, Brian Hoskins, Matthew Daniels, Advait Madhavan, Lei Wan, Tiffany Santos, Michael Tran, Jordan Katine, Patrick Braganca, Mark Stiles, Jabez J. McClelland
The increasing scale of neural networks and their growing application space have produced a demand for more energy and memory efficient artificial-intelligence-specific hardware. Avenues to mitigate the main issue, the von Neumann bottleneck, include in

Knowledge Mining in Cybersecurity: From Attack to Defense

July 18, 2022
Author(s)
Khandakar Ashrafi Akbar, Sadaf MD Halim, Yibo Hu, Anoop Singhal, Latifur Khan, Bhavani Thuraisingham
In the fast-evolving world of Cybersecurity, an analyst often has the difficult task of responding to new threats and attack campaigns within a limited amount of time. If an analyst fails to do so, this can lead to severe consequences for the system under

Magnetic Uncertainties for Compact Kibble Balances: An Investigation

July 18, 2022
Author(s)
Shisong Li, Stephan Schlamminger
The Kibble balance has become one of the major instruments for realizing the mass unit, the kilogram, in the revised international system of units (SI). Researchers at about a dozen national metrology institutes are actively working with Kibble balances

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
