Identifiability Matters: Revealing the Hidden Recoverable Condition in Unbiased Learning to Rank

Kavli Affiliate: Zhuo Li | First 5 Authors: Mouxiang Chen, Chenghao Liu, Zemin Liu, Zhuo Li, Jianling Sun | Summary: Unbiased Learning to Rank (ULTR) aims to train unbiased ranking models from biased click logs, by explicitly modeling a generation process for user behavior and fitting click data based on examination hypothesis. Previous research found […]

Clump-scale Gas Infall in High-mass Star Formation: a Multi-transition View with JCMT HCN (4–3) Mapping

Kavli Affiliate: Ke Wang | First 5 Authors: Fengwei Xu, Ke Wang, Yuxin He, Jingwen Wu, Lei Zhu | Summary: Gas infall motions play a crucial role in high-mass star formation and are characterized by observable signatures in the form of blue-shifted asymmetric spectral line profiles ("blue profiles"). However, the connection between blue profiles and […]

Hybrid Strangeon Stars

Kavli Affiliate: Renxin Xu | First 5 Authors: Chen Zhang, Yong Gao, Cheng-Jun Xia, Renxin Xu, | Summary: It was conjectured that the basic units of the ground state of bulk strong matter may be strange-clusters called strangeons, and they can form self-bound strangeon stars that are highly compact. Strangeon stars can develop a strange […]

Second-order optical response of superconductors induced by supercurrent injection

Kavli Affiliate: Jing Wang | First 5 Authors: Linghao Huang, Jing Wang, , , | Summary: We develop a theory of the nonlinear optical responses in superconducting systems in the presence of a dc supercurrent. The optical transitions between particle-hole pair bands across the superconducting gap are allowed in clean superconductors as the inversion-symmetry-breaking by […]

On the maximum local mean order of sub-k-trees of a k-tree

Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Tianlong Ma, Fengming Dong, Xian’an Jin, | Summary: For a k-tree T, a generalization of a tree, the local mean order of sub-k-trees of T is the average order of sub-k-trees of T containing a given k-clique. The problem whether the largest local mean order […]

The Impact of Silence on Speech Anti-Spoofing

Kavli Affiliate: Zhuo Li | First 5 Authors: Yuxiang Zhang, Zhuo Li, Jingze Lu, Hua Hua, Wenchao Wang | Summary: The current speech anti-spoofing countermeasures (CMs) show excellent performance on specific datasets. However, removing the silence of test speech through Voice Activity Detection (VAD) can severely degrade performance. In this paper, the impact of silence […]

A Close Look at Ly$α$ Emitters with JWST/NIRCam at $zapprox3.1$

Kavli Affiliate: Linhua Jiang | First 5 Authors: Yixiao Liu, Y. Sophia Dai, Stijn Wuyts, Jia-Sheng Huang, Linhua Jiang | Summary: We study 10 spectroscopically confirmed Ly$alpha$ emitters (LAEs) at $zapprox3.1$ in the UDS field, covered by JWST/NIRCam in the PRIMER program. All LAEs are detected in all NIRCam bands from F090W to F444W, corresponding […]
