Characterization of Noise in CMOS Ring Oscillators at Cryogenic Temperatures

July 12, 2023
Author(s)
Prashansa Mukim, Pragya Shrestha, Advait Madhavan, Nitin Prasad, Jason Campbell, Forrest Brewer, Mark Stiles, Jabez J. McClelland
Allan deviation provides a means to characterize the time-dependence of noise in oscillators and potentially identify the source characteristics. Measurements on a 130nm, 7-stage ring oscillator show that the Allan deviation declines from 300K to 150K as

Classification and Authentication of Materials using Prompt Gamma Ray Activation Analysis

July 12, 2023
Author(s)
Nathan Mahynski, Jacob Monroe, David Sheen, Rick L. Paul, Heather H. Chen-Mayer, Vincent K. Shen
Prompt gamma ray activation analysis (PGAA) is a non-destructive nuclear measurement technique that quantifies isotopes present in a sample. Here, we use PGAA spectra to train different types of models to elucidate how discriminating these spectra are for

Graphene-Based Star-Mesh Resistance Networks

July 12, 2023
Author(s)
Dean G. Jarrett, Ching-Chen Yeh, Shamith Payagala, Alireza Panna, Yanfei Yang, Linli Meng, Swapnil Mhatre, Ngoc Thanh Mai Tran, Heather Hill, Dipanjan Saha, Randolph Elmquist, David B. Newell, Albert Rigosi

SMET: Semantic Mapping of CVE to ATT&CK and its Application to Cyber Security

July 12, 2023
Author(s)
Abdeen Basel, Ehab Al-Sheer, Anoop Singhal, Latifur Khan, Kevin Hamlen
Cybercriminals relentlessly pursue vulnerabilities across cyberspace to exploit software, threatening the security of individuals, organizations, and governments. Although security teams strive to establish defense measures to thwart attackers, the

Measuring Firebrand Heat Flux with a Thin-Skin Calorimeter

July 11, 2023
Author(s)
Amy Mensch, Savannah Wessies, Anthony Hamins, Jiann C. Yang
While the impact of wildland-urban interface fires is growing, firebrand exposure is a significant but not well understood contributor to fire spread. The ignition threat of firebrand exposures can be characterized by measuring the heat transfer of glowing

Multi-mode Gaussian State Analysis with Total Photon Counting

July 11, 2023
Author(s)
Arik Avagyan, Scott Glancy, Emanuel Knill
The continuing improvement in the qualities of photon-number-resolving (PNR) detectors opens new possibilities for measuring quantum states of light. In this work we consider the question of what properties of an arbitrary multi-mode Gaussian state are

On the challenge of unambiguous identification of fentanyl analogs: exploring measurement diversity using standard reference mass spectral libraries

July 11, 2023
Author(s)
Arun Moorthy, Edward Erisman, Anthony J. Kearsley, Yuxue Liang, Edward Sisco, William E. Wallace
Fentanyl analogs are a class of designer drugs that are particularly challenging to unambiguously identify due to the mass spectral and retention time similarities of unique compounds. In this paper, we use agglomerative hierarchical clustering to explore

2023 NIST OWM S&T Analysis

July 7, 2023
Author(s)
Lisa Warfield, Loren Minnich, Jan Konijnenburg, Gloria Diane Lee, Juana Williams
The NIST OWM Analysis is submitted to assist the Weights and Measures community as it deliberates on items before the 2023 NCWM Annual Conference. NIST OWM offers these comments and recommendations based upon information and input available as of the date

Artificial Intelligence-Assisted Edge Computing for Wide Area Monitoring

July 7, 2023
Author(s)
Bin Hu, Hamid Gharavi
The massive digital information generated in conjunction with the ever-increasing phasor measurement data in the power grid has led to a tremendous constraint on the analysis and timely processing of real-time data. Under these conditions, leveraging

Coherent Laser Ranging of Deforming Objects in Fires at Sub-Millimeter Precision

July 7, 2023
Author(s)
Matthew Hoehler, Artur A. Chernovsky, Matthew Bundy, Esther Baumann
This paper applies coherent Frequency Modulated Continuous Wave Light Detection and Ranging to capture three-dimensional measurements of objects in fire at meters of stand-off distance. Despite the presence of flame depths up to 1.5 m obscuring the target
