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

3D Imaging from Passive Scattered Light using Plenoptic Information

July 15, 2022
Author(s)
James Leger, Connor Hashemi, Jarvis Haupt, Di Lin, Tianqi Luo, Abhinav Sambasivan, Takahiro Sasaki, Joseph Talgader, Gary Meyer, Michael Tetzlaff, Erich N. Grossman
We use plenoptic measurements of visible, infrared, and THz radiation to locate and image objects that are hidden from direct view by detecting their passive radiation scattered from rough surfaces.

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
