Electronic Commensuration of a Spin Moire Superlattice in a Layered Magnetic Semimetal

February 4, 2025
Author(s)
Takashi Kurumaji, Nisarga Paul, Shiang Fang, Paul Neves, Mingu Kang, Jonathan White, Taro Nakajima, David Graf, Linda Ye, Mun Chan, Takehito Suzuki, Jonathan Denlinger, Chris Jozwiak, Aaron Bostwick, Eli Rotenberg, Jeffrey Lynn, Efthimios Kaxiras, Riccardo Comin, Liang Fu, Joseph Checkelsky, Yang Zhao
Spin moiré superlattices (SMSs) have been proposed as a magnetic analog of crystallographic moiré systems and a source of electron minibands offering vector-field moiré tunability and Berry curvature effects. However, it has proven challenging to realize

Nanocalorimetry for plasma metrology relevant to semiconductor fabrication

February 4, 2025
Author(s)
John Diulus, Carles Corbella Roca, Feng Yi, David LaVan, Berc Kalanyan, Mark McLean, Lakshmi Ravi Narayan, William Osborn, James Maslar, Andrei Kolmakov
This letter reports on pilot tests of microfabricated nanocalorimeters as a metrology platform for the rapid (sub-100 ms response time) and sensitive detection of neutral radicals generated by reactive cold plasmas, typical in plasma cleaning applications

The NIST Cybersecurity Framework (CSF) 2.0 (Greek translation)

February 4, 2025
Author(s)
Cherilyn Pascoe, Stephen Quinn, Karen Scarfone
The NIST Cybersecurity Framework (CSF) 2.0 provides guidance to industry, government agencies, and other organizations to manage cybersecurity risks. It offers a taxonomy of high-level cybersecurity outcomes that can be used by any organization —

A bilateral comparison of 227Th activity standards between NPL and NIST

February 3, 2025
Author(s)
Andrew Fenwick, Denis Bergeron, Brittany Broder, Emma Bendall, Jeffrey Cessna, Sean Collins, Leticia Pibida, Natasha Ramirez, Elisa Napoli
The National Physical Laboratory (United Kingdom) and the National Institute of Standards and Technology (United States) each determined the massic activity and effective separation time of a common solution of 227Th. Measurements at both laboratories were

Resilience-Runtime Tradeoff Relations for Quantum Algorithms

February 3, 2025
Author(s)
Luis Pedro Garcia-Pintos, Tom O'Leary, Tanmoy Biswas, Jacob Bringewatt, Lukasz Cincio, Lucas Brady, Yi-Kai Liu
A leading approach to algorithm design aims to minimize the number of operations in an algorithm's compilation. One intuitively expects that reducing the number of operations may decrease the chance of errors. This paradigm is particularly prevalent in

Variation of radiometric throughput with simple perturbations

February 3, 2025
Author(s)
Eric Shirley
This work considers the effects of changes of distance, centering and tilting of optical elements on radiometric throughput. Analytical formulas for leading-order effects are compared to numerical calculations for validation purposes.

Insights on grain refinement of Al-Mn-Fe-Si alloy via in situ reaction during laser direct energy deposition

February 2, 2025
Author(s)
Qingyu Pan, Fan Zhang, Deepak Vikraman Pillai, Zilong Zhang, Yufeng Zheng, Lang Yuan, Monica Kapoor, John Carsley, Xiaoyuan Lou
In the present work, we studied the grain refinement by adding in situ reactants, pure titanium (Ti) or a combination of Ti and boron (B), and investigated the governing mechanism in Al-Mn-Fe-Si 3104 alloy made by laser direct energy deposition (DED)

Error Floor Prediction with Markov Models for QC-MDPC Codes

February 1, 2025
Author(s)
Sarah Arpin, Jun Bo Lau, Ray Perlner, Angela Robinson, Valentin Vasseur, Jean-Pierre Tillich
Quasi-cyclic moderate-density parity check (QC-MDPC) code-based encryption schemes under iterative decoders offer highly-competitive performance in the quantum-resistant space of cryptography, but the decoding-failure rate (DFR) of these algorithms are not

Impacts of household water demands and water heater delivery temperatures on opportunistic premise plumbing pathogens (OPPPs) in a residential setting

February 1, 2025
Author(s)
Alshae Logan, Jumana Aljafari, Visesh Uppoor, Tania Ullah, Jennifer Dootz
Efforts aimed towards water and energy conservation within residential buildings may create enhanced conditions for Opportunistic Premise Plumbing Pathogens (OPPPs) growth. To investigate this issue, a study was conducted to assess the effect of water

Layer ensemble averaging for fault tolerance in memristive neural networks

February 1, 2025
Author(s)
Osama Yousuf, Brian Hoskins, Karthick Ramu, Mitchell Fream, William Borders, Advait Madhavan, Matthew Daniels, Andrew Dienstfrey, Jabez McClelland, Martin Lueker-Boden, Gina Adam
Advancements in continual learning with artificial neural networks have been fueled in large part by scaling network dimensionalities. As this scaling continues, conventional computing systems are becoming increasingly inefficient due to the von Neumann

QM-ARC: QoS-aware Multi-tier Adaptive Cache Replacement Strategy

February 1, 2025
Author(s)
Lydia Ait Oucheggou, Abdella Battou, Jalil Boukhobza, Stephane Rubini
Distributed data-centric systems, such as Named Data Networking, utilize in-network caching to reduce application latency by buffering relevant data in high-speed memory. However, the significant increase in data traffic makes expanding memory capacity

Aflatoxin B1-induced DNA adduct formation in murine kidney and liver

January 31, 2025
Author(s)
Pawel Jaruga, Vladimir Vartanian, Irina Minko, M Miral Dizdar, Amanda McCullough, R. Stephen Lloyd
Aflatoxicosis is a life-threatening nephrotoxic condition arising from eating foods highly contaminated with aflatoxin-producing molds. Additionally, chronic aflatoxin exposures are linked to enhanced hepatocellular carcinomas. Using recent advances in

Calibrating laser Doppler anemometers utilizing an optical chopper

January 31, 2025
Author(s)
Christopher Crowley, Iosif Isaakovich Shinder, Michael R. Moldover, Joey Boyd, James Filla, Aaron Johnson
Laser Doppler anemometers (LDAs) use scattered light to determine velocity components of a flowing fluid. The operating principal of LDAs is simple conceptually; however, it is impractical to trace the LDA-determined velocities to the SI by characterizing

Designing Usable Audio for Voting Systems: Best Practices and a Test Approach

January 31, 2025
Author(s)
Lynn Baumeister, Whitney Quesenbery, Sharon J. Laskowski
Voting systems must support multiple interaction modes: presenting information both visually and auditorily, accepting navigation and selections from both screen touches and key presses on a tactile controller. The best practices outlined in this document

Security Property Verification by Transition Model

January 31, 2025
Author(s)
Chung Tong Hu
Verifying the security properties of access control policies is a complex and critical task. The policies and their implementation often do not explicitly express their underlying semantics, which may be implicitly embedded in the logic flows of policy

Using enantioselective biosensors to evolve asymmetric biocatalysts

January 30, 2025

d'Oelsnitz Simon, Wantae Kim, Haley Hardtke, Svetlana Ikonomova, Nina Alperovich, Olga Vasilyeva, Michael James, Eric Zigon, Charlie Johnson, Andrew Ellington, Quincey Justman, Michael Springer, Jessie Zhang, Pamela Silver, David Ross
Biocatalysts are championed for their exquisite stereochemistry, but slow chromatographic separations necessary to measure enantiomeric excess can bottleneck their development. Prokaryotic transcription factors can address this limitation by transducing
