AutoEIS: automated Bayesian model selection and analysis for electrochemical impedance spectroscopy

August 9, 2023
Author(s)
Runze Zhang, Robert Black, Debashish Sur, Parisa Karimi, Kangming Li, Brian DeCost, John Scully, Jason Hattrick-Simpers
Electrochemical Impedance Spectroscopy (EIS) is a powerful tool for electrochemical analysis; however, its data can be challenging to interpret. Here, we introduce a new open-source tool named AutoEIS that assists EIS analysis by automatically proposing

Quantum Lego Expansion Pack: Enumerators from Tensor Networks

August 9, 2023
Author(s)
ChunJun Cao, Michael Gullans, Brad Lackey, Zitao Wang
We provide the first tensor network method for computing quantum weight enumerator polynomials in the most general form. As a corollary, if a quantum code has a known tensor network construction of its encoding map, our method produces an algorithm that

14 Examples of How LLMs Can Transform Materials Science and Chemistry: A Reflection on a Large Language Model Hackathon

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

The Association of Biomolecular Resource Facilities Proteome Informatics Research Group Study on Metaproteomics (iPRG-2020)

August 7, 2023
Author(s)
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

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
