Multi-code Benchmark on Ti K-edge X-ray Absorption Spectra of Ti-O Compounds

January 11, 2024
Author(s)
Fanchen Meng, Benedikt Maurer, Fabian Peschel, Sencer Selcuk, Xiaohui Qu, Mark S Hybertsen, Christian Vorwerk, Claudia Draxl, John Vinson, Deyu Lu
X-ray absorption spectroscopy (XAS) is an element-specific materials characterization technique that is sensitive to structural and electronic properties. First-principles simulated XAS has been widely used as a powerful tool to interpret experimental

Calculating Pairwise Similarity of Polymer Ensembles via Earth Mover's Distance

January 10, 2024
Author(s)
Jiale Shi, Dylan Walsh, Weizhong Zou, Nathan Rebello, Michael Deagen, Katharina Fransen, Xian Gao, Debra Audus, Bradley Olsen
Synthetic polymers, in contrast to small molecules and deterministic biomacromolecules, are typically ensembles composed of polymer chains with varying numbers, lengths, sequences, chemistry, and topologies. While numerous approaches exist for measuring

Characterizing Styrene Monomer and Oligomers by SEC/MALS/VISC/DRI

January 10, 2024
Author(s)
Andre Striegel
Worldwide polystyrene (PS) production in 2020 was approximately 27 million metric tons, distributed among many nations, making it one of the most heavily imported and exported chemicals. Commercially produced PS usually possesses a broad molar mass

Threshold and Laser Conversion in Nanostructured-Resonator Parametric Oscillators

January 10, 2024
Author(s)
Haixin Liu, Grant Brodnik, Jizhao Zang, David Carlson, Jennifer Black, Scott Papp
We explore optical parametric oscillation (OPO) in nanophotonic resonators, enabling arbitrary, nonlinear phase matching and nearly lossless control of energy conversion. Such pristine OPO laser converters are determined by nonlinear light-matter

Magnetism and Fermiology of Kagome Magnet YMn6Sn4Ge2

January 7, 2024
Author(s)
Hari Bhandari, Rebecca Dally, Peter E. Siegfried, Resham Regmi, Kirrily Rule, Songxue Chi, Jeffrey Lynn, I. Mazin, Nirmal J. Ghimire
Kagome lattice magnets are an interesting class of materials as they can host topological properties in their magnetic and electronic structures. YMn6Sn6 is one such compound in which a series of competing magnetic phases is stabilized by an applied

Adversarial Machine Learning: A Taxonomy and Terminology of Attacks and Mitigations

January 4, 2024
Author(s)
Apostol Vassilev, Alina Oprea, Alie Fordyce, Hyrum Andersen
This NIST AI report develops a taxonomy of concepts and defines terminology in the field of adversarial machine learning (AML). The taxonomy is built on survey of the AML literature and is arranged in a conceptual hierarchy that includes key types of ML

A Fully Integrated, Automatically Generated DC-DC Converter Maintaining > 75% Efficiency From 398 K Down to 23 K Across Wide Load Ranges in 12-nm FinFET

January 1, 2024
Author(s)
Anhang Li, Jeongsup Lee, Prashansa Mukim, Brian Hoskins, Pragya Shrestha, David Wentzloff, David Blaauw, Dennis Sylvester, Mehdi Saligane
This paper presents a fully integrated recursive successive-approximation switched capacitor (RSC) DC-DC converter implemented using an automatic cell-based layout generation in 12 nm FinFET technology. A novel design methodology is demonstrated based on

Analyzing "grey zone" Turbulent Kinetic Energy predictions in the Boundary Layer from three WRF PBL Schemes over New York City and comparison to Aircraft measurements

January 1, 2024
Author(s)
Austin Hope, Israel Lopez Coto, Kristian Hajny, Jay M Tomlin, Robert Kaeser, Brian Stirm, Anna Karion, James Whetstone, Paul Shepson
We conduct WRF simulations at multiple resolutions down to the "grey zone" (9 km, 3 km, 1 km, 333 m) to examine boundary layer turbulence in three planetary boundary layer (PBL) schemes: the well-established MYNN PBL scheme and the two newest PBL schemes

Towards Opportunistic Radar Sensing Using Millimeter-wave WiFi

January 1, 2024
Author(s)
Jian Wang, Jack Chuang, Samuel Berweger, Camillo Gentile, Nada T. Golmie
Sensing with communication waveforms has drawn growing interest thanks to the ubiquitous availability of wireless networks. However, the required sensing resources may not always be available in a communication system. In addition, the communication system

Applying the Effective Bond Energy Formalism (EBEF) to Describe the Sigma (s) Phase in the Co-Cr-Ni-Re System

December 30, 2023
Author(s)
Julio Cesar Pereira Dos Santos, Sean Griesemer, Nathalie Dupin, Ursula R. Kattner, Chuan Liu, Daniela Ivanova, Thomas Hammerschmidt, Suzana Fries, Chris Wolverton, Carelyn E. Campbell
Proper descriptions of Topologically Closed-Packed (TCP) phases in thermodynamic databases are essential to adequately design new alloys. Thus, the recently introduced Effective Bond Energy Formalism (EBEF) is used in this work to describe the sigma (σ)

Employing Word-Embedding for Schema Matching in Standard Lifecycle Management

December 29, 2023
Author(s)
Hakju Oh, Boonserm Kulvatunyou, Albert T. Jones, Tim Finin
Today, businesses rely on numerous information systems to achieve their production goals and improve their global competitiveness. Semantically integrating those systems is essential for businesses to achieve both. To do so, businesses must rely on

Quantification of mRNA in Lipid Nanoparticles Using Mass Spectrometry

December 26, 2023
Author(s)
Mark Lowenthal, Abigail Antonishek, Karen W. Phinney
Lipid nanoparticle-encapsulated messenger RNA (LNP-mRNA) holds great promise as a novel modality for treating a broad range of diseases. The ability to quantify mRNA accurately in therapeutic products helps to ensure consistency and safety. Here we
