ATIC: Automated Testbed for Interference Testing in Communication Systems

December 25, 2023
Author(s)
Michelle Pirrone, Keith Forsyth, Jordan Bernhardt, Dan Kuester, Aric Sanders, Duncan McGillivray, Adam Wunderlich
The proliferation of communication devices and systems has led to increasingly complex and dynamic spectral environments. This greatly impacts the operations of a multitude of organizations, including commercial entities, academic and non-commercial

Electrical and Electroluminescence Evaluation of 17 Year Old Monocrystalline Silicon Building Integrated Photovoltaic Modules

December 25, 2023
Author(s)
Andrew Shore, Tali Schlenoff, Bakary Coulibaly, David Navon, Stephanie Moffitt, Brian P. Dougherty, Behrang Hamadani
Longterm reliable operation of photovoltaic modules is necessary to ensure the technology is key to reducing the cost of solar energy. However, degradation mechanisms in the field are not always consistent or predictable. We present a dataset of 72

Intra-grain local luminescence properties of CdSe0.1Te0.9 Thin Films

December 25, 2023
Author(s)
Ganga Neupane, Behrang Hamadani, David Albin, Joel Duenow, Matthew Reese, Susanna Thon
We report on the local photoluminescence properties of grains and grain boundaries of CdSe0.1Te0.9 thin film deposited by the colossal grain growth method using a wide-field hyperspectral imaging technique. We observed significant variations in the

System-Level Evaluation of 5G NR UE-Based Relays

December 25, 2023
Author(s)
Samantha Gamboa Quintiliani, Aziza Ben Mosbah, Wesley Garey, Chunmei Liu, Richard A. Rouil
The notion of UE-based relays started with the introduction of Proximity Services (ProSe) and Device-to-Device (D2D) communication, and evolved with the adaptation of the Fifth Generation (5G) New Radio (NR) interface. While the main goal of relays is to

Ultra-Low Phase Noise Frequency Division with Array of Direct Digital Synthesizers

December 25, 2023
Author(s)
Marco Pomponio, Archita Hati, Craig Nelson
In this article, we present a four-channel direct digital synthesis (DDS) design that operates with a common clock ranging from 500 MHz to 24 GHz and generates output frequencies up to 1.75 GHz. A key feature of this board is its custom field-programmable

Cybersecurity of Genomic Data

December 20, 2023
Author(s)
Ronald Pulivarti, Natalia Martin, Frederick R. Byers, Justin Wagner, Justin Zook, Samantha Maragh, Jennifer McDaniel, Kevin Wilson, Martin Wojtyniak, Brett Kreider, Ann-Marie France, Sallie Edwards, Tommy Morris, Jared Sheldon, Scott Ross, Phillip Whitlow
Genomic data has enabled the rapid growth of the U.S. bioeconomy and is valuable to the individual, industry, and government because it has multiple intrinsic properties that in combination make it different from other types of high value data which

Expansivity of fused quartz glass measured within 6 x 10^-10 /K

December 20, 2023
Author(s)
Patrick Egan
Thermal expansion sometimes dominates uncertainty in a precision measurement. A cell-based refractometer has been designed at NIST which targets 10^-6 relative uncertainty in the measurement of helium refractivity; in terms of absolute refractive index at

Uniform Laws and Regulations in the Areas of Legal Metrology and Fuel Quality

December 18, 2023
Author(s)
Lisa Warfield, John McGuire, Katrice Lippa
NIST Handbook 130 includes a compilation of model laws and regulations and related interpretations and guidelines designed to encourage uniformity in adoption and implementation of weights and measures laws and regulations. The model laws and regulations

Recommendations from the Ocean Carbonate System Intercomparison Forum: Quantifying and reducing uncertainties in the calculations of carbonate system equilibrium in the oceans

December 14, 2023
Author(s)
Brendan Carter, Jonathan Sharp, Andrew Dickson, Marta Alvarez, Michael Fong, Maribel Garcia-Ibanez, Ryan Woosley, Takeshita Yuichiro, Leticia Barbero, Robert Byrne, Wei-Jun Cai, Melissa Chierici, Simon Clegg, Regina Easley, Andrea Fassbender, Kalla Fleger, Xinyu Li, Macarena Martin-Mayor, Katelyn Schockman, Aleck Wang Zhaohui
The ocean carbonate system is critical to monitor because it plays a major role in regulating Earth's climate and marine ecosystems. It is monitored using a variety of measurements, and it is commonly understood that all major components of the seawater

Spatially-Dependent Model for Rods and Cones in the Retina

December 14, 2023
Author(s)
Daniel M. Anderson, Danielle Brager, Anthony J. Kearsley
We develop a mathematical model for photoreceptors in the retina. We focus on rod and cone outer segment dynamics and interactions with a nutrient source associated with the retinal pigment epithelium cells. Rod and cone densities (number per unit area of

Advancements in Computational Wind Engineering Workshop Report

December 13, 2023
Author(s)
Long Phan
In September 2022, the Structural Engineering Institute of the American Society of Civil Engineers commenced a project under National Institute of Standards and Technology Contract No. 133ND22PNB730391 to develop workshops on Advancement in Computational

Automated interpretation of firearm mark comparison results

December 13, 2023
Author(s)
Martin Baiker-Sorensen, Ivo Alberink, Laura Granell, Leen van der Ham, Erwin J.A.T. Mattijssen, Erich Smith, Johannes A. Soons, Peter Vergeer, Xiaoyu Alan Zheng
In this article an automated approach for interpretation of firearm mark comparison results is presented. First, similarity scores are derived for marks typically encountered on primers of fired cartridge cases: aperture shear striations as well as

Kerr-induced synchronization of a cavity soliton to an optical reference

December 13, 2023
Author(s)
Gregory Moille, Jordan Stone, Michal J. Chojnacky, Curtis Menyuk, Kartik Srinivasan
The phase-coherent frequency division of a stabilized optical reference laser to the microwave domain is made possible by optical-frequency combs (OFCs). OFC-based clockworks lock one comb tooth to a reference laser, which probes a stable atomic transition

Maintenance and Operations of Manufacturing Digital Twins

December 13, 2023
Author(s)
Alp Akcay, Stephan Biller, Boon Ping Gan, Christoph Laroque, Guodong Shao
Digital twins have become an important element in smart manufacturing. As any other product, digital twins also have a lifecycle, starting from specifying the requirements of the digital twins until their decommissioning. As part of the Manufacturing and
