Kavli Affiliate: Huawei Zhang | First 5 Authors: Fangfei Shi, Donald W. Kurtz, Daniel L. Holdsworth, Hideyuki Saio, Margarida S. Cunha | Summary: We report the frequency analysis of a known roAp star, HD 86181 (TIC 469246567), with new inferences from TESS data. We derive the rotation frequency to be $nu_{rot}$ = 0.48753 $pm$ 0.00001d$^{-1}$. […]
Kavli Affiliate: Herre S. J. Van Der Zant | First 5 Authors: Javier López-Cabrelles, Samuel Mañas-Valero, Iñigo J. Vitórica-Yrezábal, Makars Šiškins, Martin Lee | Summary: Through rational chemical design, and thanks to the hybrid nature of metal-organic frameworks (MOFs), it is possible to prepare molecule-based 2D magnetic materials stable at ambient conditions. Here, we illustrate […]
Kavli Affiliate: Michael P. Brenner | First 5 Authors: Katy Blumer, Subhashini Venugopalan, Michael P. Brenner, Jon Kleinberg, | Summary: We analyze a dataset of retinal images using linear probes: linear regression models trained on some "target" task, using embeddings from a deep convolutional (CNN) model trained on some "source" task as input. We use […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Björn Sbierski, Max Geier, An-Ping Li, Matthew Brahlek, Robert G. Moore | Summary: The combination of two-dimensional Dirac surface states with s-wave superconductivity is expected to generate localized topological Majorana zero modes in vortex cores. Putative experimental signatures of these modes have been reported for heterostructures […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Ziyan Xu, Gregory J. Herczeg, Christopher M. Johns-Krull, Kevin France, | Summary: We present an analysis of wind absorption in the C II ${lambda}1335$ doublet towards 40 classical T Tauri stars with archival far-ultraviolet (FUV) spectra obtained by the Hubble Space Telescope. Absorption features produced by […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Arghajit Jana, Neeraj Kumari, Prantik Nandi, Sachindra Naik, Arka Chatterjee | Summary: We study the nature of the changing-look Active Galactic Nucleus NGC 1566 during its June 2018 outburst. During the outburst, the X-ray intensity of the source rises up to ~25-30 times compared to its quiescent […]
Kavli Affiliate: Graham R. Fleming | First 5 Authors: Yusuke Yoneda, Eric A. Arsenault, Kaydren Orcutt, Masakazu Iwai, Graham R. Fleming | Summary: Photosystem II is crucial for life on Earth as it provides oxygen as a result of photoinduced electron transfer and water splitting reactions. The excited state dynamics of the photosystem II-reaction center […]
Kavli Affiliate: Alyosha Molnar | First 5 Authors: Oscar Castañeda, Zachariah Boynton, Seyed Hadi Mirfarshbafan, Shimin Huang, Jamie C. Ye | Summary: All-digital millimeter-wave (mmWave) massive multi-user multiple-input multiple-output (MU-MIMO) receivers enable extreme data rates but require high power consumption. In order to reduce power consumption, this paper presents the first resolution-adaptive all-digital receiver ASIC […]
