Himanshu Neema, Harmon Nine, Thomas Roth
Cyber-Physical Systems (CPS) require seamless integration of physical and computation components through communication networks. They often contain sub-systems from different physical domains (e.g., electrical, mechanical, and electronic) that must

Impact of Strong Atmospheric Turbulence on Two-Way Optical Time Transfer

May 8, 2023
Author(s)
Laura Sinclair, Emily Caldwell, Jean-Daniel Deschenes, Hugo Bergeron, William C. Swann, Nathan Newbury
Frequency comb based optical time transfer can provide femtosecond-level timing which will support future clock networks. However, for long-distance terrestrial links, non-reciprocal atmospheric turbulence induces a timing penalty. Here, we quantify this

One-Step Traceability with NIST on a Chip: A Case for the Emergence of Quantum-Based Methods for Metrology and Sensing of Pressure, Vacuum, Temperature, Electric Fields, Mass, Force, and Torque, all enabled by the New SI

Author(s)
Aly Artusio-Glimpse, Christopher L. Holloway, Matt Simons, Nik Prajapati, Drew Rotunno, Samuel Berweger, Kaleb Campbell, Maitreyi Jayaseelan
Absolute electric field measurements present a "chicken-and-egg" situation where calibration of field probes relies on accurate knowledge of the field while precise determination of the field involves measurements with a calibrated probe. Metrology

Thermal environment impact on HfOx RRAM operation: A nanoscale thermometry and modeling study

May 8, 2023

Matthew West, Georges Pavlidis, Robert Montgomery, Fabia Farlin Athena, Muhammad Jamil, Andrea Centrone, Samuel Graham, Eric Vogel
As the demand for computing applications capable of processing large datasets increases, there is a growing need for new in-memory computing technologies that avoid the von Neumann bottleneck. Oxide-based resistive random-access memory (RRAM) devices are a

Using the Kibble Principle for One-Step Traceability for Mass, Force, and Torque

May 8, 2023
Author(s)
Stephan Schlamminger, Leon Chao, Zane Comden, John-Edward Draganov, Thapelo Given Mametja
Many technologies contributed to the 2019 revision of the international system of units. Notable is a mechanical apparatus, the Kibble balance. It allows the precise comparison of electrical power to mechanical power with relative uncertainties close to 1
