Isotropic Nature of the Metallic Kagome Ferromagnet Fe 3 Sn 2 at High Temperatures

March 20, 2021
Author(s)
Rebecca Dally, Daniel Phelan, Nicholas Bishop, Nirmal J. Ghimire, Jeffrey Lynn
Anisotropy and competing exchange interactions have emerged as two central ingredients needed for centrosymmetric materials to exhibit topological spin textures. Fe 3Sn 2 is thought to have these ingredients as well, as it has recently been discovered to

Measurement of 227 Ac Impurity in 225 Ac using Decay Energy Spectroscopy

March 20, 2021
Author(s)
A. D. Tollefson, C. M. Smith, M. H. Carpenter, M. P. Croce, M. E. Fassbender, K. D. John, K. E. Koehler, L. M. Lilley, E. M. O'Brien, Daniel Schmidt, B. W. Stein, Joel Ullom, M. D. Yoho, D. J. Mercer
225Ac is a valuable medical isotope for targeted alpha therapy, but 227Ac is an undesirable byproduct of an accelerator-based synthesis method under investigation. Sufficient detector sensitivity is critical for quantifying the trace impurity of 227Ac

CD19 Expression Analysis Using Two Flow cytometric Quantitative Schemes: An approach for Identifying Robust B-cell Reference Control Materials

March 19, 2021
Author(s)
Hao-Wei Wang, Paul Patrone, Anthony Kearsley, Jessica Watson, Liang Lim, Jothir Pichaandi, Olga Ornatsky, Daniel Majonis, Rukmini Bhardwaj, Howard Mostowski, Steven Bauer, Heba Degheidy, Lili Wang
Cell-based therapies have emerged as a novel approach to treat cancer and other conditions. Quantitative flow cytometry plays an increasingly important role in predicting therapy outcome in a wide range of hematologic malignancies. Several studies

Exploring the First High Entropy Thin Film Libraries: Composition spread-controlled Crystalline Structure

March 19, 2021
Author(s)
Thi X. Nguyen, Yen-Hsun Su, Jason Hattrick-Simpers, Takahiro Nagata, Howard Joress, Kao-Shuo Chang, Suchismita Sarker, Apurva Mehta, Jyh-Ming Ting
Thin films of two types of high-entropy oxides (HEOs) have been deposited on 76.2 mm Si wafers using combinatorial sputter deposition. In one type of the oxides, (MgZnMnCoNi)Ox, all the metals have a stable divalent oxidation state and similar cationic

Intelligent Task Caching in Edge Cloud via Bandit Learning

March 19, 2021
Author(s)
Hamid Gharavi
Task caching, based on edge cloud, aims to meet the latency requirements of computation- intensive and data-intensive tasks (such as augmented reality). However, current task caching strategies are generally based on the unrealistic assumption of knowing

Damage tolerant design of additively manufactured metallic components subjected to cyclic loading: State of the art and challenges

March 18, 2021
Author(s)
Uwe Zerbst, Giovanni Bruno, Jean-Yves Buffiere, Thomas Wegener, Tao Wu, Xiang Zhang, Nikolai Kashaev, Giovanni Meneghetti, Nik Hrabe, Mauro Madia, Tiago Werner, Kai Hildgenburg, Radek Proch?zka, Martina Koukol?kov?, Jan D?ugan, Benjamin M?ller, Stefano Beretta, Alexander Evans
Undoubtedly, a better understanding and the further development of approaches for damage tolerant component design of AM parts are among the most significant challenges currently facing the use of these new technologies. This article presents a thorough

Sensors and Machine Learning Models to Prevent Cooktop Ignition and Ignore Normal Cooking

March 18, 2021
Author(s)
Amy Mensch, Anthony Hamins, Andy Tam, John Lu, Kathryn Markell, Christina You, Matthew Kupferschmid
Cooking equipment is involved in nearly half of home fires in the United States, with cooktop fires the leading cause of deaths and injuries in cooking-related fires. In this study, we evaluate 16 electrochemical, optical, temperature and humidity sensors

Combinatorial Test Generation for Multiple Input Models with Shared Parameters

March 17, 2021
Author(s)
Chang Rao, Nan Li, Yu Lei, Jin Guo, YaDong Zhang, Raghu N. Kacker, D. Richard Kuhn
Combinatorial testing typically considers a single input model and creates a single test set that achieves t-way coverage. This paper addresses the problem of combinatorial test generation for multiple input models with shared parameters. We formally

Control of Magnetoelectric Coupling in the Co 2 Y-Type Hexaferrites

March 16, 2021
Author(s)
Chang B. Park, Kwang W. Shin, Sae H. Chun, Jun H. Lee, Yoon S. Oh, Steven M. Disseler, Colin A. Heikes, William D. Ratcliff, Woo-Suk Noh, Jae-Hoon Park, Kee H. Kim
We comprehensively investigated the magnetic, ferroelectric, and ME properties of Ba 2-xSr xCo 2(Fe 1-yAl y) 12O 22 single crystals in broad doping ranges of Sr (1.0 less than or equal to} x less than or equal to} 1.8) and Al (0.00 less than or equal to} y

Isogenies on twisted Hessian curves

March 16, 2021
Author(s)
Dustin Moody, Thinh Dang, Fouazou Lontouo Perez, Emmanuel Fouotsa
Elliptic curves are typically defined by Weierstrass equations. Given a kernel, the well-known Vélu's formula shows how to explicitly write down an isogeny between Weierstrass curves. However, it is not clear how to do the same on other forms of elliptic

Molecular View on Mechanical Reinforcement in Polymer Nanocomposites

March 16, 2021
Author(s)
Ruikun Sun, Matthew Melton, Niloofar Safaie, Jr. Ferrier, Shiwang Cheng, Yun Liu, Xiaobing Zuo, Yangyang Wang
The microscopic origin of mechanical enhancement in polymer nanocomposites (PNCs) is investigated through the combination of rheology and small-angle neutron scattering. It is shown that in the absence of an extensive particle network, the molecular

A Trusted Federated System to Share Granular Data Among Disparate Database Resources

March 15, 2021
Author(s)
Joanna DeFranco, David F. Ferraiolo, D. Richard Kuhn, Joshua D. Roberts
Sharing data between different organizations is a challenge primarily due to database management systems (DBMSs) being different types that impose different schemas to represent and retrieve data. In addition, maintaining security and privacy is a concern

Fully phase-stabilized 1 GHz turnkey frequency comb at 1.5 mm
