Positive-Negative Equal Contrastive Loss for Semantic Segmentation

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Lingfei Xuan, Wenxuan Wang, Tianxiang Zhang, Jiangyun Li | Summary: The contextual information is critical for various computer vision tasks, previous works commonly design plug-and-play modules and structural losses to effectively extract and aggregate the global context. These methods utilize fine-label to optimize the model […]

The effect of obstacles near a silo outlet on the discharge of soft spheres

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Kirsten Harth, Dmitry Puzyrev, Ralf Stannarius, | Summary: Soft smooth particles in silo discharge show peculiar characteristics, including, for example, non-permanent clogging and intermittent flow. This paper describes a study of soft, low-frictional hydro-gel spheres in a quasi-2D silo. We enforce a more competitive behavior […]

Reading and Writing: Discriminative and Generative Modeling for Self-Supervised Text Recognition

Kavli Affiliate: Jing Wang | First 5 Authors: Mingkun Yang, Minghui Liao, Pu Lu, Jing Wang, Shenggao Zhu | Summary: Existing text recognition methods usually need large-scale training data. Most of them rely on synthetic training data due to the lack of annotated real images. However, there is a domain gap between the synthetic data […]

SASV Based on Pre-trained ASV System and Integrated Scoring Module

Kavli Affiliate: Zhuo Li | First 5 Authors: Yuxiang Zhang, Zhuo Li, Wenchao Wang, Pengyuan Zhang, | Summary: Based on the assumption that there is a correlation between anti-spoofing and speaker verification, a Total-Divide-Total integrated Spoofing-Aware Speaker Verification (SASV) system based on pre-trained automatic speaker verification (ASV) system and integrated scoring module is proposed and […]

Radiative feedback on supermassive star formation: the massive end of the Population III initial mass function

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Daisuke Toyouchi, Kohei Inayoshi, Wenxiu Li, Zoltán Haiman, Rolf Kuiper | Summary: Supermassive stars (SMSs) with masses of $M_ast simeq 10^4$–$10^5~{rm M_odot}$ are invoked as possible seeds of high-redshift supermassive black holes, but it remains under debate whether their protostar indeed acquires sufficient mass via gas accretion […]

Design and analysis of electrothermal metasurfaces

Kavli Affiliate: Zhuo Li | First 5 Authors: Xiu Liu, Zhuo Li, Zexiao Wang, Hyeong Seok Yun, Sheng Shen | Summary: Electrothermal metasurfaces have attracted extensive attention due to their ability to dynamically control thermal infrared radiation. Although previous studies were mainly focused on the metasurfaces with infinite unit cells, the finite-size effect can be […]

Ionized Outflows in Nearby Quasars are Poorly Coupled to their Host Galaxies

Kavli Affiliate: Ran Wang | First 5 Authors: Juan Molina, Luis C. Ho, Ran Wang, Jinyi Shangguan, Franz E. Bauer | Summary: We analyze Multi Unit Spectroscopic Explorer observations of nine low-redshift (z < 0.1) Palomar-Green quasar host galaxies to investigate the spatial distribution and kinematics of the warm, ionized interstellar medium, with the goal […]

Probable Dormant Neutron Star in a Short-Period Binary System

Kavli Affiliate: Subo Dong | First 5 Authors: Tsevi Mazeh, Simchon Faigler, Dolev Bashi, Sahar Shahaf, Niv Davidson | Summary: We have identified 2XMM J125556.57+565846.4, at a distance of 600 pc, as a binary system consisting of a normal star and a probable dormant neutron star. Optical spectra exhibit a slightly evolved F-type single star, […]

Is there a sub-parsec-scale jet base in the nearby dwarf galaxy NGC 4395?

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jun Yang, Xiaolong Yang, Joan M. Wrobel, Zsolt Paragi, Leonid I. Gurvits | Summary: NGC 4395 is a dwarf galaxy at a distance of about 4.3 Mpc (scale: ~0.021 pc mas$^{-1}$). It hosts an intermediate-mass black hole (IMBH) with a mass between ~10$^4$ and ~10$^5$ solar […]
