EVOQUER: Enhancing Temporal Grounding with Video-Pivoted BackQuery Generation

no code implementations10 Sep 2021 Yanjun Gao, Lulu Liu, Jason Wang, Xin Chen, Huayan Wang, Rui Zhang

Given a query and an untrimmed video, the temporal grounding model predicts the target interval, and the predicted video clip is fed into a video translation task by generating a simplified version of the input query.

Evidence of topological nodal lines and surface states in the centrosymmetric superconductor SnTaS2

no code implementations7 Dec 2020 Wenqing Chen, Lulu Liu, Wentao Yang, Dong Chen, Zhengtai Liu, Yaobo Huang, Tong Zhang, Haijun Zhang, Zhonghao Liu, D. W. Shen

Utilizing angle-resolved photoemission spectroscopy and first-principles calculations, here, we demonstrate the existence of topological nodal-line states and drumheadlike surface states in centrosymmetric superconductor SnTaS2, which is a type-II superconductor with a critical transition temperature of about 3 K. The valence bands from Ta 5d orbitals and the conduction bands from Sn 5p orbitals cross each other, forming two nodal lines in the vicinity of the Fermi energy without the inclusion of spin-orbit coupling (SOC), protected by the spatial-inversion symmetry and time-reversal symmetry.
