Impact-Ionization-Based High-Endurance One-Transistor Bulk CMOS Cryogenic Memory

March 31, 2025
Author(s)
Pragya Shrestha, Alexander Zaslavsky, Valery Ortiz Jimenez, Jason Campbell, Curt Richter
This paper presents a high-endurance capacitorless one-transistor (1T) cryogenic memory, fabricated in a 180 nm bulk CMOS technology, with a high memory window of (107 I1/I0 sense current ratio) and prolonged retention. The memory is enabled by the

Refrigerant Properties Development R&D: Final Report to U.S. Department of Energy on Interagency Agreements 892434-19-S-EE000031 and 892434-23-S-EE000120

A series of experiments are reported on the burning behavior of single items and assemblies commonly found in offices and residences, including chairs, sofas, mattresses with pillows and bedclothes, and some miscellaneous items such as laptops, bookshelves

Thoughts on the Kibble-Robinson Theory

March 31, 2025
Author(s)
Lorenz Keck, Kumar Arumugam, Leon Chao, Zane Comden, Frank Seifert, David Newell, Darine El Haddad, Stephan Schlamminger
We revisit the Kibble-Robinson Theory (KRT), first proposed in 2014 by Kibble and Robinson, which significantly simplifies the construction and operation of Kibble balances. We conducted a theoretical investigation of the theory's assumptions, using a

Marine debris impacts on Hawaiian green sea turtles (Chelonia mydas): High prevalence of hook-and-line fishing gear in strandings

March 29, 2025
Author(s)
Marthe Hoiberg, Jan Borgelt, Philip Mostert, Shawn Murakawa, Summer Martin, Jon Gelman, Jennifer Lynch, Francesca Verones
Stranding data are critical for monitoring threats to sea turtles. By analyzing four decades of green turtle (Chelonia mydas) strandings from the Main Hawaiian Islands, we elucidate temporal and spatial trends. In Hawai'i, fibropapillomatosis (FP) has been

Author(s)
Chieh-Chih Yeh, Harold Hatch, Adithya Sreenivasan, Bhuvnesh Bharti, Vincent Shen, Zachary Sherman, Thomas Truskett
This study explores the structure and phase behavior of monolayers of model colloids with short-range attractions and long-range repulsions, The model is motivated by recent experiments of hard-sphere-like microspheres that effectively interact via

Development of SAFT-based coarse-grained models of carbon dioxide and nitrogen

Author(s)
Alexandros Chremos, William P. Krekelberg, Harold Hatch, Daniel Siderius, Nathan Mahynski, Vincent Shen
We develop coarse-grained models for carbon dioxide (CO2 ) and nitrogen (N2 ) that capture the vapor-liquid equilibria of their single components and their binary mixtures over a wide range of temperatures and pressures. To achieve this, we used an
