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

Joint Determination of Reactor Antineutrino Spectra from 235U and 239Pu Fission using the Daya Bay and PROSPECT Experiments

February 22, 2022
Author(s)
Hans Pieter Mumm, Denis E. Bergeron, Mark Tyra, Svetlana Nour, Jerome LaRosa, The PROSPECT Collaboration
A joint determination of the reactor antineutrino spectra resulting from the fission of 235U and 239Pu has been carried out by the Daya Bay and PROSPECT collaborations. This letter defines the level of compatibility of 235U spectrum measurements from the

Joint Measurement of the 235U Antineutrino Spectrum with PROSPECT and STEREO

February 22, 2022
Author(s)
Hans Pieter Mumm, Denis E. Bergeron, Mark Tyra, Jerome LaRosa, Svetlana Nour, PROSPECT collaboration, STEREO collaboration
The PROSPECT and STEREO collaborations present a combined measurement of the pure 235U antineutrino spectrum, with site specific corrections and effects dependent on the separate detectors removed. The spectral measurements of the two highest-precision

Securing Telehealth Remote Patient Monitoring Ecosystem

February 22, 2022
Author(s)
Jennifer Cawthra, Nakia R. Grayson, Ronald Pulivarti, Bronwyn J. Hodges, Jason Kuruvilla, Kevin Littlefield, Julie Snyder, Sue Shuqiu Wang, Ryan Williams, Kangmin Zheng
Increasingly, healthcare delivery organizations (HDOs) are relying on telehealth and remote patient monitoring (RPM) capabilities to treat patients at home. RPM is convenient and cost-effective, and its adoption rate has increased. However, without

Development of Kudzu (Pueraria montana var. lobata) Reference Materials for the Determination of Isoflavones and Toxic Elements

February 21, 2022
Author(s)
J. Andreas Lippert, Kate Rimmer, Melissa M. Phillips, Michael Nelson, Chuck Barber, Laura J. Wood, Marie Ale, Kaitlyn Chieh, Stephen Long, Colleen E. Bryan Sallee, Shannon Whitehead, Katherine E. Sharpless, James H. Yen, Danica Raynaud, Joesph Betz, Adam Kuszak, Stephen Wise
As part of a collaboration with the Office of Dietary Supplements at the National Institutes of Health (NIH-ODS), the National Institute of Standards and Technology (NIST) recently issued a suite of new botanical matrix Reference Materials (RMs) and

OSAC Registry Implementation Survey: 2021 Report

February 21, 2022
Author(s)
Allison Getz
This report provides a detailed look at the respondents and the implementation status of 46 standards that were posted on the OSAC Registry as of March 2021. It also serves to create a baseline to measure the year-over-year progress in the implementation

Prospects for assembling ultracold radioactive molecules from laser-cooled atoms

February 21, 2022
Author(s)
Jacek Klos, Hui Li, Eite Tiesinga, Svetlana Kotochigova
Molecules with unstable isotopes often contain heavy and deformed nuclei and thus possess a high sensitivity to parity-violating effects, such as Schiff moments. Currently the best limits on Schiff moments are set with diamagnetic atoms. Polar molecules
