Single-Component Superconductivity in UTe2 at Ambient Pressure

July 21, 2023
Author(s)
Florian Theuss, Avi Shragai, Gael Grissonnanche, Ian Hayes, Shanta Saha, Yun Eo, Alonso Suarez, Tatsuya Shishidou, Nicholas Butch, Johnpierre Paglione, B. Ramshaw
The microscopic mechanism of Cooper pairing in a superconductor leaves its fingerprint on the symmetry of the order parameter. UTe2 has been inferred to have a multi-component order parameter that entails exotic effects like time reversal symmetry breaking

Functional Analyses of Single Nucleotide Polymorphic Variants of the DNA Glycosylase NEIL1 Present in sub-Saharan African Populations

July 20, 2023
Author(s)
Jamie Zuckerman, Irina Minko, Melis Kant, Pawel Jaruga, Miral M. Dizdar, Amanda McCullough, R. Stephen Lloyd
Nei-like glycosylase 1 (NEIL1) is a DNA repair enzyme that initiates the base excision repair (BER) pathway to cleanse the human genome of damage. Its substrate specificity includes several common base modifications formed under oxidative stress conditions

Internal and external harmonics in bi-cyclide coordinates

July 20, 2023
Author(s)
Hans Volkmer, Brandon Alexander, Howard Cohl
The Laplace equation in three-dimensional Euclidean space is R-separable in bi-cyclide coordinates leading to harmonic functions expressed in terms of Lamé–Wangerin functions called internal and external bi-cyclide harmonics. An expansion for a fundamental

Inverse Transform Sampling for Efficient Doppler-Averaged Spectroscopy Simulations

July 14, 2023
Author(s)
Drew Rotunno, Nik Prajapati, Samuel Berweger, MATTHEW SIMONS, Aly Artusio-Glimpse, Amy Robinson, chris holloway
We present a thermal velocity sampling method for calculating Doppler-broadened atomic spectra, which more efficiently reaches a smooth limit than regular velocity weighted sampling. The method uses equal-population sampling of the 1-D thermal distribution

RECENT DEVELOPMENTS IN ONTOLOGY STANDARDS AND THEIR APPLICABILITY TO BIOMANUFACTURING

July 14, 2023
Author(s)
Milos Drobnjakovic, Boonserm Kulvatunyou, Simon P. Frechette, Vijay Srinivasan
ISO and IEC have jointly initiated, and recently issued, a series of standards (the ISO/IEC 21838 series) for top-level ontologies. These standards have been used by industrial consortia to develop and disseminate standards for mid-level ontologies to ease

A Human-centered Framework to Update Digital Twins

July 13, 2023
Author(s)
Peter O. Denno, Deogratias Kibira
Developing a digital twin (DT) involves establishing (1) a predictive capability (a model) relevant to the application, (2) means to collect data from the physical counterpart, and (3) means to apply the collected data to the model. Ideally, with these

Discovery and Recognition of Formula Conceptsusing Machine Learning

July 13, 2023
Author(s)
Howard Cohl, Bela Gipp, Moritz Schubotz, Philipp Scharpf
Citation-based Information Retrieval (IR) methods for scientific documents have proven effective for IR applications, such as Plagiarism Detection or Literature Recommender Systems in academic disciplines that use many references. In science, technology

Evaluating the thermal performance of perovskite SrSnO3 field effect transistors

July 13, 2023
Author(s)
Bivek Bista, Prafful Golani, Fengdeng Liu, Tristan Truttmann, Georges Pavlidis, Andrea Centrone, Bharat Jalan, Steven Koester
Given the ever increasing, global electricity consumption, improving the efficiency and reliability of high-power electronics is of paramount importance. Ultra-wide band gap (> 3.4 eV) semiconductors have shown the potential to be used in the next

Magnetic tunnel junction-based crossbars: improving neural network performance by reducing the impact of non-idealities

July 13, 2023
Author(s)
William Borders, Nitin Prasad, Brian Hoskins, Advait Madhavan, Matthew Daniels, Vasileia Gerogiou, Tiffany Santos, Patrick Braganca, Mark Stiles, Jabez J. McClelland
Increasingly higher demand in chip area and power consumption for more sophisticated artificial neural networks has catalyzed efforts to develop architectures, circuits, and devices that perform like the human brain. However, many novel device technologies

Characterization of Noise in CMOS Ring Oscillators at Cryogenic Temperatures

July 12, 2023
Author(s)
Prashansa Mukim, Pragya Shrestha, Advait Madhavan, Nitin Prasad, Jason Campbell, Forrest Brewer, Mark Stiles, Jabez J. McClelland
Allan deviation provides a means to characterize the time-dependence of noise in oscillators and potentially identify the source characteristics. Measurements on a 130nm, 7-stage ring oscillator show that the Allan deviation declines from 300K to 150K as

Classification and Authentication of Materials using Prompt Gamma Ray Activation Analysis

July 12, 2023
Author(s)
Nathan Mahynski, Jacob Monroe, David Sheen, Rick L. Paul, Heather H. Chen-Mayer, Vincent K. Shen
Prompt gamma ray activation analysis (PGAA) is a non-destructive nuclear measurement technique that quantifies isotopes present in a sample. Here, we use PGAA spectra to train different types of models to elucidate how discriminating these spectra are for

Graphene-Based Star-Mesh Resistance Networks

July 12, 2023
Author(s)
Dean G. Jarrett, Ching-Chen Yeh, Shamith Payagala, Alireza Panna, Yanfei Yang, Linli Meng, Swapnil Mhatre, Ngoc Thanh Mai Tran, Heather Hill, Dipanjan Saha, Randolph Elmquist, David B. Newell, Albert Rigosi
