Characterization Method of Ionization Chamber Type Detectors

February 25, 2022
Author(s)
Leticia Pibida, Ronaldo Minniti, Miles McCord
A wide variability in accuracy exists among commercial radiation detection instruments used to measure exposure rate or ambient dose equivalent rate. These instruments are used to measure both the radiation background and the radiation field produced by

Coalition and Threshold Hash-Based Signatures

February 25, 2022
Author(s)
John M. Kelsey, Stefan Lucks
We show how to construct a threshold version of stateful hash-based signature schemes like those defined in XMSS (defined in RFC8391) and LMS (defined in RFC8554). Our techniques assume a trusted dealer and secure point-to-point communications; are

Toward Robust Autotuning of Noisy Quantum Dot Devices

February 25, 2022
Author(s)
Joshua Ziegler, Thomas McJunkin, Emily Joseph, Sandesh Kalantre, Benjamin Harpt, Donald Savage, Max Lagally, Mark Eriksson, Jacob Taylor, Justyna Zwolak
The current autotuning approaches for quantum dot (QD) devices, while showing some success, lack an assessment of data reliability. This leads to unexpected failures when noisy or otherwise low-quality data is processed by an autonomous system. In this

In-situ Stress Measurements During CO Adsorption onto Pt

February 24, 2022
Author(s)
David Raciti, Gery R. Stafford, Kathleen Schwarz, John Vinson
The change in surface stress associated with the adsorption and oxidative stripping of carbon monoxide (CO) on (111)-textured Pt is examined using the wafer curvature method in 0.1 M KHCO3 electrolyte. The curvature of the Pt cantilever electrode was

Recent Advances and Applications of Deep Learning Methods in Materials Science

February 24, 2022
Author(s)
Kamal Choudhary, Brian DeCost, Chi Chen, Anubhav Jain, Francesca Tavazza, Ryan Cohn, Cheol WooPark, Alok Choudhary, Ankit Agrawal, Simon Billinge, Elizabeth Holm, ShyuePing Ong, Chris Wolverton
Deep learning (DL) is one of the fastest growing topics in materials data science, with rapidly emerging applications spanning atomistic, image-based, spectral, and textual data modalities. Deep learning allows analysis of unstructured data and automated

Smart Cities and Communities: A Key Performance Indicators Framework

February 24, 2022
Author(s)
Martin Serrano, Edward Griffor, David A. Wollman, Michael Dunaway, Martin Burns, Sokwoo Rhee, Chris Greer
This publication presents research findings and scientific work that advance the development and progression of smart city and community measurement methodology. The term 'smart,' as used in the phrase 'smart cities,' is defined here as the efficient use

Toward a New Primary Standardization of Radionuclide Massic Activity Using Microcalorimetry and Quantitative Milligram-Scale Samples

February 24, 2022
Author(s)
Ryan P. Fitzgerald, Bradley Alpert, Dan Becker, Denis E. Bergeron, Richard Essex, Kelsey Morgan, Svetlana Nour, Galen O'Neil, Dan Schmidt, Gordon A. Shaw, Daniel Swetz, R. Michael Verkouteren, Daikang Yan
We present a new paradigm for the primary standardization of radionuclide activity per mass of solution (Bq/g). Two key enabling capabilities are 4π decay-energy spectrometry using chip-scale sub-Kelvin microcalorimeters and direct realization of mass by

Verifying Executability of SysML Behavior Models Using Alloy Analyzer

February 24, 2022
Author(s)
Jeremy Doerr, Conrad Bock, Raphael Barbau
This report presents an approach to verifying executability of system behavior models by treating them as logical constraint problems solved using Alloy Analyzer, a non-proprietary software tool supporting a textual language for logical constraints and

Ransomware Risk Management: A Cybersecurity Framework Profile

February 23, 2022
Author(s)
Bill Fisher, Murugiah Souppaya, William Barker, Karen Scarfone
Ransomware is a type of malicious attack where attackers encrypt an organization's data and demand payment to restore access. In some instances, attackers may also steal an organization's information and demand an additional payment in return for not
