Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Lu Chen, , , | Summary: In cosmology, the fine-structure constant can affect the whole ionization history. However, the previous works confine themselves to the recombination epoch and give various strong constraints on the fine-structure constant. In this paper, we also take the reionization epoch […]
Kavli Affiliate: Jing Wang | First 5 Authors: Hye-Jin Park, Se-Heon Oh, Jing Wang, Yun Zheng, Hong-Xin Zhang | Summary: We present H I gas kinematics and star formation activities of NGC 6822, a dwarf galaxy located in the Local Group at a distance of ~ 490 kpc. We perform profile decomposition of line-of-sight velocity […]
Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Beibei Zhang, , , | Summary: We study a large deviation principle for a reflected stochastic partial differential equation on infinite spatial domain. A new sufficient condition for the weak convergence criterion proposed by Matoussi, Sabbagh and Zhang ({it Appl. Math. Optim.} 83: 849-879, 2021) […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Runqiu Xiao, Hangting Chen, Zhenduo Zhao, Zihan Zhang | Summary: This paper describes the systems developed by the HCCL team for the NIST 2021 speaker recognition evaluation (NIST SRE21).We first explore various state-of-the-art speaker embedding extractors combined with a novel circle loss to obtain discriminative […]
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 […]
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 […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Dong-Wei Bao, Michael S. Brotherton, Pu Du, Jacob N. McLane, T. E. Zastrocky | Summary: In this third paper of the series reporting on the reverberation mapping (RM) campaign of active galactic nuclei with asymmetric H$beta$ emission-line profiles, we present results for 15 Palomar-Green (PG) quasars […]
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 […]
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 […]
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 […]
