Eswaran Subrahmanian, Guillaume Sousa Amaral, Talapady N. Bhat, Mary C. Brady, Kevin G. Brady, Jacob Collard, Sarra Chouder, Philippe Dessauw, Alden A. Dima, John T. Elliott, Walid Keyrouz, Nicolas Lelouche, Benjamin Long, Rachael Sexton, Ram D. Sriram
With the advent of the COVID-19 pandemic, there was the hope that data science approaches could help discover means for understanding, mitigating, and treating the disease. This manifested itself in the creation of the COVID-19 Open Research Dataset (CORD

How to Scale a Phish: An Investigation into the Use of the NIST Phish Scale

August 7, 2023
Author(s)
Shanee Dawkins, Jody Jacobs
Organizations around the world are using the NIST Phish Scale (NPS) in their phishing awareness training programs. As a new metric for measuring human phish-ing detection difficulty of phishing emails, the use of the NPS by phishing training implementers

Peering into the Phish Bowl: An Analysis of Real-World Phishing Cues

August 7, 2023
Author(s)
Lorenzo Neil, Shanee Dawkins, Jody Jacobs, Julia Sharp
Organizations use simulated phishing awareness train-ing exercises to help users identify, detect, and defend against the ever-changing phishing threat landscape. Realistic phishing emails are used to test users' ability to spot a phish from visible cues

Pratik Jagtap, Michael Hoopmann, Ben Neely, Anthony Harvey, Lukas Kall, Yasset Perez-Riverol, Milky Abajorga, Julie Thomas, Susan Weintraub, Magnus Palmblad
Metaproteomics research using mass spectrometry data has emerged as a powerful strategy to understand the mechanisms underlying microbiome dynamics and the interaction of microbiomes with their immediate environment. Recent advances in sample preparation

Cybersecurity Definitions for Non-Experts

August 6, 2023
Author(s)
Lorenzo Neil, Julie Haney, Kerrianne Buchanan, Charlotte Healy
Despite the importance of cybersecurity, there is no standard definition nor common terminology for explaining cybersecurity. Existing definitions largely target academics or technical experts but not non-experts (those without cybersecurity proficiency)

Effects of as-built surface with varying number of contour passes on high-cycle fatigue behavior of additively manufactured nickel alloy 718

August 5, 2023
Author(s)
Orion Kafka, Jake Benzing, Nicholas Derimow, Philipp Schumacher, Lucas Koepke, Chad Beamer, Donald Godfrey, Nik Hrabe
High cycle fatigue life of laser-powder bed fusion (L-PBF) parts depends on several factors; as-built surfaces, when present, are a particular concern. This work measures as-built L-PBF surfaces with X-ray computed tomography, and uses rotating beam

Augmented Reality Interface for Robot-Sensor Coordinate Registration

August 4, 2023
Author(s)
Vinh Nguyen, Xiaofeng Liu, Jeremy Marvel
Accurate registration of Cartesian coordinate systems is vital to facilitate advanced metrological solutions of industrial robots in production environments. Conducting coordinate registration between industrial robots and their metrological systems

Imaging local luminescence variations in CdSe0.1Te0.9 thin films grown by the colossal grain growth process.

August 4, 2023
Author(s)
Ganga Neupane, Andrew Winchester, Nicolas Marquez Peraca, David Albin, Joel Duenow, Matthew Reese, Sujitra Pookpanratana, Susanna Thon, Behrang Hamadani
Clear visualization and understanding of luminescence properties of grain interiors and grain boundaries in polycrystalline thin-film photovoltaic materials are crucial to achieving high-performance solar cells. Luminescence-based measurements, for example

Quantum-Based Microwave Modulated Waveforms

August 4, 2023
Author(s)
Akim Babenko, Nathan Flowers-Jacobs, Anna Fox, Paul Dresselhaus, Zoya Popovic, Samuel P. Benz
This paper presents a superconducting voltage source that generates microwave modulated waveforms with quantum-based stability. The voltage source - an RF Josephson Arbitrary Waveform Synthesizer (RF-JAWS) - uses a superconducting IC with an array of 4500

Composite Spin Hall Conductivity from Non-Collinear Antiferromagnetic Order

August 3, 2023
Author(s)
Steve Novakov, Peter B. Meisenheimer, Grace A. Pan, Patrick Kezer, Nguyen M. Vu, Alexander Grutter, Ryan F. Need, Julia Mundy, John Heron
Non-collinear antiferromagnets are an exciting new platform for studying intrinsic spin Hall effects, phenomena that arise from the materials' band structure, Berry phase curvature, and linear response to an external electric field. In contrast to

Maximally Edge-Connected Realizations and Kundu's k-factor Theorem

August 3, 2023
Author(s)
James Shook
A simple graph $G$ with edge-connectivity $\lambda(G)$ and minimum degree $\delta(G)$ is maximally edge connected if $\lambda(G)=\delta(G)$. In 1964, given a non-increasing degree sequence $\pi=(d_1},\ldots,d_n})$, Jack Edmonds showed that there is a

Synthetic Aperture RF Reception using Rydberg Atoms
