Mechanical Regulation of Oral Epithelial Barrier Function

April 25, 2023
Author(s)
Eun Jin Lee, Yoontae Kim, Paul Salipante, Anthony Kotula, Dana Graves, Stella Alimperti
Epithelial cell function is modulated by mechanical forces imparted by the extracellular environment. The transmission of forces onto the cytoskeleton by modalities such as mechanical stress and matrix stiffness is necessary to address by the development

Phishing With a Net: The NIST Phish Scale and Cybersecurity Awareness

April 25, 2023
Author(s)
Shanee Dawkins, Jody Jacobs
Orienting an entire organization toward sound security practices is an important, but non-trivial undertaking. A starting point for many organizations is to build a robust security awareness program, training employees to recognize and respond to security

Noise-resilient deep tomographic imaging

April 24, 2023
Author(s)
Zhen Guo, Zhiguang Liu, George Barbastathis, Qihang Zhang, Michael Glinsky, Bradley Alpert, Zachary H. Levine
X-ray tomography is a non-destructive imaging technique that reveals the interior of an object from its projections at different angles. Under limited-angle and low-photon sampling, a regularization prior is required to retrieve a high-fidelity

Trap-Integrated Superconducting Nanowire Single-Photon Detectors with Improved RF Tolerance for Trapped-Ion Qubit State Readout

April 24, 2023
Author(s)
Benedikt Hampel, Daniel Slichter, Dietrich Leibfried, Richard Mirin, Sae Woo Nam, Varun Verma
State readout of trapped-ion qubits with trap-integrated detectors can address important challenges for scalable quantum computing, but the strong radio frequency (rf) electric fields used for trapping can impact detector performance. Here, we report on

Forward and Inverse design of high $T_C$ superconductors with DFT and deep learning

April 21, 2023
Author(s)
Daniel Wines, Kevin Garrity, Tian Xie, Kamal Choudhary
We developed a multi-step workflow for the discovery of next-generation conventional superconductors. 1) We started with a Bardeen–Cooper–Schrieffer (BCS) inspired pre-screening of 55000 materials in the JARVIS-DFT database resulting in 1736 materials with

Monitoring Protein Complexation with Polyphosphazene Polyelectrolyte Using Automated Dynamic Light Scattering Titration and Asymmetric Flow Field Flow Fractionation and Protein Recognition Immunoassay

April 21, 2023
Author(s)
Michael Lueckheide, Alexander Marin, Harichandra Tagad, Nicholas Posey, Vivek Prabhu, Alexander Andrianov
Polyphosphazenes represent a class of intrinsically flexible polyelectrolytes with potent immunoadjuvant activity, which is enabled through non-covalent self-assembly with antigenic proteins by charge complexation. The formation of supramolecular complexes

Beyond Single Tetrahedron Physics of the Breathing Pyrochlore Compound Ba 3 Yb 2 Zn 5 O 11

April 20, 2023
Author(s)
Rabindranath Bag, Sachith Dissanayake, Han Yan, Zhenzhong Shi, David Graf, Eun S. Choi, Casey Marjerrison, Franz Lang, Tom Lancaster, Yiming Qiu, Wangchun Chen, Stephen J. Blundell, Andriy H. Nevidomskyy, Sara Haravifard
Recently a new class of quantum magnets, the so-called breathing pyrochlore systems, have attracted much attention due to their potential to host exotic emergent phenomena. Here, we present magnetometry, thermal, muon-spin relaxation, and polarized

Machine tool calibration: Measurement, modeling, and compensation of machine tool errors

April 20, 2023
Author(s)
Wei Gao, Soichi Ibaraki, Alkan Donmez, D. Kono, J.R.R Mayer, Yuan-Liu Chen, Karoly Szipka, Andreas Archenti, Jean-Marc Linares, N. Suzuki
Advanced technologies for the calibration of machine tools are presented. Kinematic errors independently of their causes are classified into errors within one-axis as intra-axis errors, errors between axes as inter-axis errors, and as volumetric errors. As

The field of neuromorphic computing holds great promise in terms of advancing computing efficiency and capabilities by following brain-inspired principles. However, the rich diversity of techniques employed in neuromorphic research has resulted in a lack

Size-exclusion chromatography

April 20, 2023
Author(s)
Andre Striegel
Over the past half-century, size-exclusion chromatography (SEC) has become the premier method by which to determine the molar mass (M) averages and the molar mass distribution (MMD) of natural and synthetic macromolecules. When coupled to a multiplicity of

Who Is That? Perceptual Expertise on Other-Race Face Comparisons, Disguised Face Comparisons, and Face Memory
