Discovery of multiple p-mode pulsation frequencies in the roAp star, HD 86181

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$^{-1}$. […]

Chemical design and magnetic ordering in thin layers of 2D MOFs

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 […]

Using a Cross-Task Grid of Linear Probes to Interpret CNN Model Predictions On Retinal Images

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 […]

Broadband X-Ray Observations of the 2018 Outburst of the Changing-Look Active Galactic Nucleus NGC 1566

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 […]

A Resolution-Adaptive 8 mm$^text{2}$ 9.98 Gb/s 39.7 pJ/b 32-Antenna All-Digital Spatial Equalizer for mmWave Massive MU-MIMO in 65nm CMOS

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 […]

Inhibited nonradiative decay at all exciton densities in monolayer semiconductors

Kavli Affiliate: Ali Javey | First 5 Authors: Hyungjin Kim, Shiekh Zia Uddin, Naoki Higashitarumizu, Eran Rabani, Ali Javey | Summary: Most optoelectronic devices operate at high photocarrier densities, where all semiconductors suffer from enhanced nonradiative recombination. Nonradiative processes proportionately reduce photoluminescence (PL) quantum yield (QY), a performance metric that directly dictates the maximum device […]
