Hierarchical Attention Graph for Scientific Document Summarization in Global and Local Level

Autor: Zhao, Chenlong, Zhou, Xiwen, Xie, Xiaopeng, Zhang, Yong

Scientific document summarization has been a challenging task due to the long structure of the input text. The long input hinders the simultaneous effective modeling of both global high-order relations between sentences and local intra-sentence relat

Anti-resonant acoustic waveguides enabled tailorable Brillouin scattering on chip

Autor: Lei, Peng, Xu, Mingyu, Bai, Yunhui, Chen, Zhangyuan, Xie, Xiaopeng

Empowering independent control of optical and acoustic modes and enhancing the photon-phonon interaction, integrated photonics boosts the advancements of on-chip stimulated Brillouin scattering (SBS). However, achieving acoustic waveguides with low l
