Kavli Affiliate: Yi Zhou | First 5 Authors: Yue Wang, Yi Zhou, Shaofeng Zou, , | Summary: Greedy-GQ with linear function approximation, originally proposed in cite{maei2010toward}, is a value-based off-policy algorithm for optimal control in reinforcement learning, and it has a non-linear two timescale structure with the non-convex objective function. This paper develops its tightest […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Jeremy Kowkabany, Rana Ezzeddine, Corinne Charbonnel, Ian U. Roederer, Ella Xi Wang | Summary: We present the discovery of 2MASS J05241392-0336543 (hereafter J0524-0336), a very metal-poor ([Fe/H]=-2.43 +- 0.16), highly r-process-enhanced ([Eu/Fe]= +1.34 +- 0.10) Milky Way halo field red giant star, with an ultra high Li […]
Kavli Affiliate: Ke Wang | First 5 Authors: Zhuo Chen, Jie Liu, Yubo Hu, Lei Wu, Yajin Zhou | Summary: In recent years, the underground economy is proliferating in the mobile system. These underground economy apps (UEware) make profits from providing non-compliant services, especially in sensitive areas such as gambling, pornography, and loans. Unlike traditional […]
Kavli Affiliate: Cees Dekker | First 5 Authors: Pinyao He, Allard J. Katan, Luca Tubiana, Cees Dekker, Davide Michieletto | Summary: The Kinetoplast DNA (kDNA) is a two-dimensional Olympic-ring-like network of mutually linked 2.5 kb-long DNA minicircles found in certain parasites called Trypanosomes. Understanding the self-assembly and replication of this structure are not only major […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Brittany E. Miles, Beth A. Biller, Polychronis Patapis, Kadin Worthen, Emily Rickman | Summary: We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is a $<$20 M$_mathrm{Jup}$ widely separated ($sim$8arcsec, a = 150 au), young, planetary-mass companion that shares photometric colors […]
Kavli Affiliate: Arlene Aleman | First 5 Authors: Arlene Aleman, Bruce Macintosh, Mary Anne Limbach, Mark Marley, Jeffrey Chilcote | Summary: Direct imaging characterization of extrasolar planets is often done at low spectral resolution. We model the spectrograph for the Gemini Planet Imager upgrade (GPI 2.0) and assess the instrument’s potential for allowing observers to […]
Kavli Affiliate: Jeevak Parpia | First 5 Authors: Yefan Tian, Dmytro Lotnyk, Anna Eyal, Kuang Zhang, Nikolay Zhelev | Summary: Because of the extreme purity, lack of disorder, and complex order parameter, the first-order superfluid $^3$He A-B transition is the leading model system for first order transitions in the early universe. Here we report on […]
Kavli Affiliate: Simon Groblacher | First 5 Authors: Zhi-Yuan Fan, Liu Qiu, Simon Gröblacher, Jie Li, | Summary: Microwave-optics entanglement is a vital component for building hybrid quantum networks. Here, a new mechanism for preparing stationary entanglement between microwave and optical cavity fields in a cavity optomagnomechanical system is proposed. It consists of a magnon […]
Kavli Affiliate: Kent D. Irwin | First 5 Authors: Cyndia Yu, Zeeshan Ahmed, Josef C. Frisch, Shawn W. Henderson, Max Silva-Feaver | Summary: We describe the newest generation of the SLAC Microresonator RF (SMuRF) electronics, a warm digital control and readout system for microwave-frequency resonator-based cryogenic detector and multiplexer systems such as microwave SQUID multiplexers […]
