standards (16.5 V 19.5) alongside the three CALSPEC standards, from 900 Å to 32 μm. The framework is the first of its kind to jointly infer photometric zeropoints and WD parameters (log g, Teff, AV , RV ) by simultaneously modelling both photometric and

Evidence of Antiferromagnetism in Ultrathin Metallic (111)-Oriented LaNiO3 Films

December 11, 2024
Author(s)
Margaret Kane, Purnima P. Balakrishnan, Okan Koksal, Megan Holtz, Andreas Suter, Michael R. Fitzsimmons, Chao-Yao Yang, Christoph Klewe, Paige Quarterman, Timothy R. Charlton, Andrew Herzing, Zaher Salman, Thomas Prokscha, Rossitza Pentcheva, Alexander Grutter, Yuri Suzuki
Antiferromagnets with exotic spin textures promise low-power spintronic devices with extremely high operating frequencies and resistance to external perturbations. In particular, the combination of highly tunable correlated electron physics, as in complex

Extracting Orientation and Distance-Dependent Interaction Potentials between Proteins in Solutions Using Small-Angle X-ray/Neutron Scattering

December 10, 2024
Author(s)
Yun Liu, Harold Hatch, Guangcui Yuan, Vincent Shen, Alexander Grishaev, Jainik Panchal, Marco Blanco
Nonspecific protein−protein interactions (PPIs) are key to understanding the behavior of proteins in solutions. However, experimentally measuring anisotropic PPIs as a function of orientation and distance has been challenging. Here, we propose to measure a

temo: teqp-based model optimization

December 10, 2024
Author(s)
Ian Bell
The temo library is a set of building blocks that facilitate the automation of fitting models to experimental data for thermodynamic properties. The library is written in Python to enable broad re‐use and is based upon the suite of thermodynamic equations

A 4-mW 2.2-6.9 GHz LNA in 16nm FinFET Technology for Cryogenic Applications

December 9, 2024
Author(s)
Runzhou Chen, Hamdi Mani, Phil Marsh, Richard Al Hadi, Pragya Shrestha, Jason Campbell, Christopher Chen, Hao-Yu Chen, Kosmas Galatsis, Mau-Chung Frank Chang
This work presents the design and measurement of a low-power wide-band cryogenic low-noise amplifier (LNA) that operates in a wide temperature range using 16nm FinFET technology. The LNA is packaged and measured at both room and cryogenic temperatures. It
