The COVID-19 pandemic has brought the cold chain for bio-pharmaceutical products to the spotlight. To preserve their structure and function, biopharmaceuticals such as cells, proteins and enzymes, RNA molecules, and RNA-based drugs (e.g., mRNA-based COVID

Developmental Validation of the VersaPlex(R) 27PY System

November 21, 2023
Author(s)
Kristy Lenz, Stephen McDaniel, Dawn Rabbach, Becky Steffen, Douglas Storts, Robert McLaren
The VersaPlex™ 27PY System is a short tandem repeat (STR) multiplex from Promega that co-amplifies 27 loci. This six-dye multiplex was designed for casework samples and includes loci that meet database requirements for the US (CODIS) and Europe (ESS). The

Facilitating Stakeholder Communication around AI-Enabled Systems and Business Processes

November 21, 2023
Author(s)
Edward Griffor, Matthew Bundas, Chasity Nadeau, Jeannine Shantz, Thanh Nguyen, Marcello Balduccini, Tran Son
Artificial Intelligence (AI) is often critical to the success of modern business processes. Leveraging it, however, is non-trivial. A major hurdle is communication: discussing system requirements among stakeholders with different backgrounds and goals

Knowledge Management for Data Analytics in Additive Manufacturing

November 21, 2023
Author(s)
Yeun Park, Paul Witherell, Albert T. Jones, Hyunbo Cho
As a multi-staged digital manufacturing process, Additive manufacturing (AM) inherently benefits from data analytics (DA) decision-making opportunities. The abundance of data associated with the various observations and measurements taken throughout the

2023 NIST Summary of U.S. Legal Metrology Activities

Author(s)
Lisa Warfield, Katrice Lippa, Jan Konijnenburg, Loren Minnich, Gloria Diane Lee, Juana Williams, John McGuire
The NIST Office of Weights and Measures (OWM) presents its second issue of the 2023 NIST Annual Summary of U.S. Legal Metrology Activities report. This report includes a summary of changes made to NIST Handbook 44 (2023) Specifications, Tolerances and

Monitoring Spectrometer Drift with Unsupervised Machine Learning

November 20, 2023
Author(s)
Benjamin Harding, Ziling Hu, Ashley Hiett, Frank Delaglio, Katherine Henzler- Wildman, Chad Rienstra
Solid-state NMR spectroscopy (SSNMR) is a powerful technique to probe structural and dynamic properties of molecules at an atomic level. Modern SSNMR methods employ multidimensional pulse sequences requiring data collection over a period of days to weeks

Robust Measurements for RF Fingerprinting with Constellation Patterns of Radiated Waveforms

November 20, 2023
Author(s)
Ameya Ramadurgakar, Jake Rezac, Lennart Heijnen, Kate Remley, Dylan Williams, MELINDA PIKET-MAY, Rob Horansky
We introduce a type of RF fingerprint for nondestructive, cellular device identification. The new fingerprinting algorithm, termed Eigenphones, is a data-driven technique based on a singular value decomposition of a user equipment's symbol-constellation

Scalable and robust beam shaping using apodized fish-bone grating couplers

November 20, 2023
Author(s)
Chad Ropp, Dhriti Maurya, Alexander Yulaev, Daron Westly, Gregory Simelgor, Vladimir Aksyuk
Efficient power coupling between guided and free-space optical modes requires precision spatial mode matching with apodized Bragg gratings. Yet, grating apodizations are often limited by the minimum feature size realizable by the fabrication approach
