Plasma Diagnostics of the Supernova Remnant N132D Using Deep XMM-Newton Observations with the Reflection Grating Spectrometer

Posted by klaurent MIT

Kavli Affiliate: Eric D. Miller | First 5 Authors: Hitomi Suzuki, Hiroya Yamaguchi, Manabu Ishida, Hiroyuki Uchida, Paul P. Plucinsky | Summary: We present XMM-Newton observations of N132D, the X-ray brightest supernova remnant (SNR) in the Large Magellanic Cloud (LMC), using the Reflection Grating Spectrometer (RGS) that enables high-resolution spectroscopy in the soft X-ray band. […]

Explainable Recommendation via Interpretable Feature Mapping and Evaluation of Explainability

Posted by klaurent Peking

Kavli Affiliate: Li Xin Li | First 5 Authors: Deng Pan, Xiangrui Li, Xin Li, Dongxiao Zhu, | Summary: Latent factor collaborative filtering (CF) has been a widely used technique for recommender system by learning the semantic representations of users and items. Recently, explainable recommendation has attracted much attention from research community. However, trade-off exists […]

Imaging moiré flat bands in 3D reconstructed WSe2/WS2 superlattices

Posted by klaurent Berkeley

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Hongyuan Li, Shaowei Li, Mit H. Naik, Jingxu Xie, Xinyu Li | Summary: Moir’e superlattices in transition metal dichalcogenide (TMD) heterostructures can host novel correlated quantum phenomena due to the interplay of narrow moir’e flat bands and strong, long-range Coulomb interactions1-5. However, microscopic knowledge of the […]

Unknown I.I.D. Prophets: Better Bounds, Streaming Algorithms, and a New Impossibility

Posted by klaurent Berkeley

Kavli Affiliate: Felix Fischer | First 5 Authors: José Correa, Paul Dütting, Felix Fischer, Kevin Schewior, Bruno Ziliotto | Summary: A prophet inequality states, for some $alphain[0,1]$, that the expected value achievable by a gambler who sequentially observes random variables $X_1,dots,X_n$ and selects one of them is at least an $alpha$ fraction of the maximum […]

Physics Successfully Implements Lagrange Multiplier Optimization

Posted by klaurent Berkeley

Kavli Affiliate: Eli Yablonovitch | First 5 Authors: Sri Krishna Vadlamani, Tianyao Patrick Xiao, Eli Yablonovitch, , | Summary: Optimization is a major part of human effort. While being mathematical, optimization is also built into physics. For example, physics has the principle of Least Action, the principle of Minimum Entropy Generation, and the Variational Principle. […]

Inferring the properties of a population of compact binaries in presence of selection effects

Posted by klaurent MIT

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Salvatore Vitale, Davide Gerosa, Will M. Farr, Stephen R. Taylor, | Summary: Shortly after a new class of objects is discovered, the attention shifts from the properties of the individual sources to the question of their origin: do all sources come from the same underlying population, or […]
