Materializing Rival Ground States in the Barlowite Family of Kagome Magnets: Quantum Spin Liquid, Spin Ordered, and Valence Bond Crystal States

April 14, 2020
Author(s)
Rebecca W. Smaha, Wei He, Jack Mingde Jiang, JiaJia Wen, Yi-Fan Jiang, John P. Sheckelton, Charles J. Titus, Suyin Grass Wang, Yu-Sheng Chen, Simon J. Teat, Adam A. Aczel, Yang Zhao, Guangyong Xu, Jeffrey W. Lynn, Hong-Chen Jiang, Young S. Lee
Quantum magnet display exotic phases that may be strongly influenced by small differences in structure and composition. Comprehensive structural and magnetic measurements (involving x-ray scattering, neutron scattering, and thermodynamic techniques) were

Rapid, quantitative therapeutic screening for Alzheimer's enzymes enabled by optimal signal transduction with transistors

April 14, 2020
Author(s)
Son T. Le, Michelle A. Morris, Antonio Cardone, Nicholas B. Guros, Jeffery B. Klauda, Brent A. Sperling, Curt A. Richter, Harish C. Pant, Arvind Balijepalli
We show that commercially sourced n-channel silicon field-effect transistors (nFETs) operating under closed-loop control achieve a resolution of (7.2+/-0.3)x10-3 pH units with a bandwidth of 10 Hz. The results represent an 3-fold improvement in performance

Flat-Histogram Extrapolation as a Useful Tool in the Age of Big Data

April 13, 2020
Author(s)
Nathan Mahynski, Harold Hatch, Matthew Witman, David Sheen, Jeffrey R. Errington, Vincent K. Shen
Here we review recent work by the authors to revisit the concept of extrapolating thermodynamic properties of classical systems using statistical mechanical principles. Specifically, we discuss how the combination of these principles with biased sampling

Hybrid integrated quantum photonic circuits

April 13, 2020
Author(s)
Ali Elshaari, Wolfram Pernice, Kartik Srinivasan, Oliver Benson, Val Zwiller
Recent development in chip-based photonic quantum circuits has radically impacted the ways in which we can process quantum information. However, it is challenging for any one specific integrated photonics platform to meet the stringent demands for most

A Decision Support Methodology for Integrated Machining Process and Operation Plans for Sustainability and Productivity Assessment

April 12, 2020
Author(s)
Qais Hatim, Christopher Saldana, Guodong Shao, Duckbong Kim, KC Morris, Paul Witherell, Sudarsan Rachuri, Soundar Kumara
In this paper, a systematic methodology is presented to enable environmental sustainability and productivity performance assessment for integrated process and operation plans at the machine cell level of a manufacturing system. This approach determines

Radiation damage of liquid electrolyte during focused X-ray beam photoelectron spectroscopy

April 12, 2020
Author(s)
Christopher M. Arble, Hongxuan Gou, Evgheni Strelcov, Brian D. Hoskins, Patrick Zeller, Matteo Amati, Luca Gregoratti, Andrei A. Kolmakov
Ambient pressure X-ray photoelectron spectroscopy (APXPS) has become an effective tool to interrogate chemical states at surfaces relevant to real operational conditions. Herein we employ a graphene-capped microvolume array sample platform for scanning

FRAMEWORK FOR A DIGITAL TWIN IN MANUFACTURING

April 11, 2020
Author(s)
Guodong Shao, Moneer M. Helu
Digital twin has the potential to be an important technology for achieving smart manufacturing. However, there remains a lot of confusion about the concept and how it can be implemented in real manufacturing systems, especially among small-to-medium

Advanced Temperature-Control Chamber for Resistance Standards

April 10, 2020
Author(s)
Shamith Payagala, Alireza Panna, Albert Rigosi, Dean G. Jarrett
Calibration services for resistance metrology have continued to advance their capabilities and establish new and improved methods for maintaining standard resistors. Despite the high quality of these methods, there still exist inherent limitations to the

Combinatorial Rank Attacks Against the Rectangular Simple Matrix Encryption Scheme

April 10, 2020
Author(s)
Dustin Moody, Ray A. Perlner, Daniel C. Smith-Tone, Daniel C. Apon, Javier Verbel
In 2013, Tao et al. introduced the ABC Simple Matrix Scheme for Encryption, a multivariate public key encryption scheme. The scheme boasts great efficiency in encryption and decryption, though it suffers from very large public keys. It was quickly noted
