Inhomogeneous Galactic Chemical Evolution: Modelling Ultra-Faint Dwarf Galaxies of the Large Magellanic Cloud

Kavli Affiliate: Alexander P. Ji | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Ultra-faint dwarf galaxies are among the oldest and most metal-poor galaxies in the cosmos, observed to contain no traces of gas at the present time and a high dark matter mass fraction. Understanding the chemical abundance dispersion in such […]

Comparison of Polarized Radiative Transfer Codes used by the EHT Collaboration

Kavli Affiliate: Bradford A. Benson | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Interpretation of resolved polarized images of black holes by the Event Horizon Telescope (EHT) requires predictions of the polarized emission observable by an Earth-based instrument for a particular model of the black hole accretion system. Such predictions are generated […]

Absorption of Vector Dark Matter Beyond Kinetic Mixing

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Massive vector particles are minimal dark matter candidates that motivate a wide range of laboratory searches, primarily exploiting a postulated kinetic mixing with the photon. However, depending on the high energy field content, the dominant vector dark matter (VDM) coupling […]

Augment and Criticize: Exploring Informative Samples for Semi-Supervised Monocular 3D Object Detection

Kavli Affiliate: Ke Wang | Authors: Zhenyu Li, Zhipeng Zhang, Heng Fan, Yuan He, Ke Wang, Xianming Liu, Junjun Jiang | Summary: In this paper, we improve the challenging monocular 3D object detection problem with a general semi-supervised framework. Specifically, having observed that the bottleneck of this task lies in lacking reliable and informative samples […]

Janus monolayer ScXY (X$neq$Y=Cl, Br and I) for piezoelectric and valleytronic application: a first-principle prediction

Kavli Affiliate: Ke Wang | Authors: San-Dong Guo, Xiao-Shu Guo, Shuo-Ning Si, Kai Cheng, Ke Wang, Yee Sin Ang | Summary: Coexistence of ferromagnetism, piezoelectricity and valley in two-dimensional (2D) materials is crucial to advance multifunctional electronic technologies. Here, Janus ScXY (X$neq$Y=Cl, Br and I) monolayers are predicted to be in-plane piezoelectric ferromagnetic (FM) semiconductors […]

Anatomy of plasmons in generic Luttinger semimetals

Kavli Affiliate: Jing Wang | Authors: Jing Wang, Ipsita Mandal | Summary: We investigate the parameter regimes favourable for the emergence of plasmons in isotropic, anisotropic, and band-mass asymmetric Luttinger semimetals (LSMs). An LSM harbours a quadratic band-crossing point (QBCP) in its bandstructure, where the upper and lower branches of dispersion are doubly degenrate. While […]

Contrastive Self-supervised Learning in Recommender Systems: A Survey

Kavli Affiliate: Ke Wang | Authors: Mengyuan Jing, Yanmin Zhu, Tianzi Zang, Ke Wang | Summary: Deep learning-based recommender systems have achieved remarkable success in recent years. However, these methods usually heavily rely on labeled data (i.e., user-item interactions), suffering from problems such as data sparsity and cold-start. Self-supervised learning, an emerging paradigm that extracts […]
