Microscopic Origin of Inhomogeneous Transport in Four-Terminal Tellurene Devices

December 22, 2020
Author(s)
Benjamin Kupp, Gang Qiu, Yixiu Wang, Clayton Caspeer, Thomas Mitchell (Mitch) Wallis, Joanna Atkin, Wenzhuo Wu, Peide Ye, Pavel Kabos, Samuel Berweger
Tellurene—the 2D form of elemental tellurium—provides an attractive alternative to conventional 2D semiconductors due to its high bipolar mobilities, facile solution processing, and the possibility of dopant intercalation into its 1D van der Waals lattice

Automated on-axis direct laser writing of coupling elements for photonic chips

December 21, 2020
Author(s)
Edgar Perez, Gregory Moille, Xiyuan Lu, Daron Westly, Kartik Srinivasan
Direct laser writing (DLW) has recently been used to create versatile micro-optic structures that facilitate photonic-chip coupling, like free-form lenses, free-form mirrors, and photonic wirebonds. However, at the edges of photonic chips, the top-down/off

Introduction and Clinical Validation of Metrology Standards for Immunohistochemistry

December 21, 2020
Author(s)
Emina E. Torlakovic, Seshi Sompuram, Vani Kodela, Anika Schaedle, Paul DeRose, Steve Bogen, Lili Wang
Despite the widespread integration of immunohistochemistry (IHC) into routine surgical pathology, its use suffers from significant inter-laboratory disparities. The root cause and an unsolved technical challenge is the lack of metrology standards, the

Securing Picture Archiving and Communication System (PACS) Cybersecurity for the Healthcare Sector

December 21, 2020
Author(s)
Jennifer L. Cawthra, Sue S. Wang, Bronwyn J. Hodges, Kangmin Zheng, Ryan T. Williams, Jason J. Kuruvilla, Christopher L. Peloquin, Kevin Littlefield, Bob Neimeyer
Medical imaging plays an important role in diagnosing and treating patients. The system that manages medical images is known as the picture archiving communication system (PACS) and is nearly ubiquitous in healthcare environments. PACS is defined by the

Reference materials for building product emission characterization

December 19, 2020
Author(s)
Dustin Poppendieck, Wenjuan Wei, Mengyan Gong
Building products contain chemical compounds, such as volatile organic compounds, which can be emitted into indoor air and result in human exposures in the indoor environment. The emission rate, commonly measured in environmental chambers, is a key

Bridging Analog LMR to LTE MCPTT Communications

December 18, 2020
Author(s)
Christopher J. Walton, Chic J. O'Dell
This paper explores a low-cost method to bridge analog public safety Land mobile radio (LMR) systems into a standards based Long Term Evolution (LTE) MCPTT system. Design goals included robustness, cost, and the creation of a system that closely conforms

Josephson Microwave Sources Applied to Quantum Information Systems

December 18, 2020
Author(s)
Adam J. Sirois, Manuel C. Castellanos Beltran, Anna E. Fox, Samuel P. Benz, Peter F. Hopkins
Quantum computers with thousands or millions of qubits will require a scalable solution for qubit control and readout electronics. Colocating these electronics at millikelvin temperatures has been proposed and demonstrated, but there exist significant

NIST Scientific Foundation Reviews

December 18, 2020
Author(s)
John M. Butler, Hariharan K. Iyer, Richard A. Press, Melissa Taylor, Peter Vallone, Sheila Willis
The National Institute of Standards and Technology (NIST) is a scientific research agency that works to advance measurement science, standards, and technology and that has been working to strengthen forensic science methods for almost a century. In recent

An Integrated Set of XML Tools User Guide

December 16, 2020
Author(s)
Thomas R. Kramer, Zeid Kootbally, Craig Schlenoff
This user guide describes an integrated set of C++ software tools for manipulating XML (eXtensible Markup Language) schemas and XML instance files. The tools are: - xmlSchemaParser - parses and reformats XML schema files, prints type derivation hierarchies

Heat Transfer Analysis Study for the Design of the New Polychromatic Beam Neutron Reflectometer CANDOR (Chromatic Analysis Neutron Diffractometer Or Reflectometer)

December 16, 2020
Author(s)
Lior Uzan, Juscelino Leao, Christoph W. Brocker, Daniel A. Mattes, Tanya J. Dax
A newly developed polychromatic beam neutron reflectometer CANDOR (Chromatic Analysis Neutron Diffractometer Or Reflectometer) on NG-1 at the NIST Center for Neutron research (NCNR) utilizes a wavelength-sensitive neutron detector consisting of 324

Measuring Manufacturings Significance in the USA

December 16, 2020
Author(s)
Katherine C. Morris, Douglas S. Thomas
Economic value added is a primary metric for measuring manufacturing activity; however, this metric and others exclude approximately half of the economic activity necessary for producing manufactured goods. With the recent disruption in the supply of goods
