Application of the Hybrid Satellite Network Cybersecurity Framework Profile: An Example Implementation of NIST IR 8441

February 23, 2024
Author(s)
Frederick R. Byers, Dan Mamula, Karri Meldorf, Joseph Brule, Rory Jennings, John Wiltberger, Eugene Craft, John Dombrowski, O'Ryan Lattin, Abdul Noor, Matt Yetto, Aliaksander Mamonau, Oksana Slivina, Jay Sharma, Dr. Kangmin Zheng
The space sector is transitioning towards Hybrid Satellite Networks (HSN), an aggregation of independently owned and operated terminals, antennas, satellites, payloads, or other components that comprise a satellite system. The elements of an HSN may have

Ligify: Automated genome mining for ligand-inducible transcription factors

February 21, 2024
Author(s)
Simon d'Oelsnitz, Andrew Ellington, David J. Ross
Prokaryotic transcription factors can be repurposed into biosensors for the ligand-inducible control of gene expression, but the landscape of chemical ligands for which biosensors exist is extremely limited. To expand this landscape, we developed Ligify, a

Zeeman-resolved Autler-Townes splitting in Rydberg atoms with a tunable RF resonance and a single transition dipole moment

February 21, 2024
Author(s)
Noah Schlossberger, Drew Rotunno, Aly Artusio-Glimpse, Nik Prajapati, Samuel Berweger, Dangka Shylla, Matt Simons, Christopher L. Holloway
Applying a magnetic field as a method for tuning the frequency of Autler-Townes splitting for Rydberg electrometry has recently been demonstrated. In this Letter, we provide a theoretical understanding of Rydberg electromechanically-induced-transparency

Differential scanning calorimetry (DSC): An important tool for polymer identification and characterization of plastic marine debris

February 19, 2024
Author(s)
Jennifer Lynch, Raquel Corniuk, Kayla C. Brignac, Melissa Jung, Joelle Marchiani, Wanda Weatherford
Differential scanning calorimetry (DSC), a routine thermoanalytical method in material science, is gaining utility in plastic pollution research to improve polymer identification. We optimized a DSC method, experimentally testing pan types, temperature

Entropy Driven Incommensurate Structures in the Frustrated Kagome Staircase Co3V2O8

February 18, 2024
Author(s)
Joel Helton, Nyrissa Rogado, Robert Cava, Jeffrey Lynn
Co3V2O8 features spin-3/2 moments arrayed on a kagome staircase lattice. A spin density wave with a continuously evolving propagation vector of ⃗k = (0, δ, 0), showing both incommensurate states and multiple commensurate lock-ins, is observed at

Evaluating Common-View Time Transfer Using a Low-Cost Dual-Frequency GNSS Receiver

February 15, 2024
Author(s)
Aidan Montare, Andrew Novick, Jeffrey Sherman
Common-view time transfer can be performed using either single (L1) or dual (L1/L2) frequency global navigation satellite system (GNSS) signals. Using dual-frequency receivers for common-view has advantages but has historically been of significantly higher

Optical frequency division & pulse synchronization using a photonic-crystal microcomb injected chip-scale mode-locked laser

February 15, 2024
Author(s)
Chinmay Shirpurkar, Jizhao Zang, Ricardo Bustos-Ramirez, David Carlson, Travis Briles, Lawrence R. Trask, Srinivas V. Pericherla, Di Huang, Ashish Bhardwaj, Gloria E. Hoefler, Scott Papp, Peter J. Delfyett
A mode-locked laser photonic integrated circuit with a repetition rate of 10 GHz is optically synchronized to a tantalabased photonic crystal resonator comb with a repetition rate of 200 GHz. The synchronization is achieved through regenerative harmonic

Application of Electrical Standards to Torque Realization: A Device to Measure up to 1Nm

February 14, 2024
Author(s)
Zane Comden, Stephan Schlamminger, Frank Seifert, David B. Newell, Leon Chao
This paper describes the next generation prototype of the Electronic NIST Torque Realizer (ENTR) project. The first prototype version (ENTR-v1) has been able to realize low-range torques (on the order of 1×10-3 Nm) to uncertainties of less than 1000 parts

Digital PCR for the Characterization of Reference Materials

February 14, 2024
Author(s)
Megan Cleveland, Hua-Jun He, Mojca Milavec, Young-Kyung Bae, Peter Vallone, Jim Huggett
Well characterized reference materials are essential to ensuring the harmonization and accuracy of nucleic acid-based tests (such as qPCR); digital PCR (dPCR) can measure the absolute concentration of a specific nucleic acid sequence in a background of non

Advancing Measurement Science for Microelectronics: CHIPS R&D Metrology Program

Marla L. Dowell, Hannah Brown, Gretchen Greene, Paul D. Hale, Brian Hoskins, Sarah Hughes, Bob R. Keller, R Joseph Kline, June W. Lau, Jeff Shainline
The CHIPS and Science Act of 2022 called for NIST to "carry out a microelectronics research program to enable advances and breakthroughs....that will accelerate the underlying R&D for metrology of next-generation microelectronics and ensure the

Overview of the NTCIR-17 FairWeb-1 Task

February 13, 2024
Author(s)
Sijie Tao, Nuo Chen, Tetsuya Sakai, Zhumin Chu, Hiromi Arai, Ian Soboroff, Nicola Ferro, Maria Maistro
This paper provides an overview of the NTCIR-17 FairWeb-1 Task. FairWeb-1 is an English web search task which seeks more than an ad-hoc web search task. Our task considers not only document relevance but also group fairness. We designed three types of
