1EDVAM:a 3D eye-tracking dataset for visual attention modeling in a virtual museum显示文摘Predicting visual attention facilitates an adaptive virtual museum environment and provides a context-aware and interactive user experience.Explorations toward development of a visual attention mechanism using eye-tracking data have so far been limited to 2D cases,and researchers are yet to approach this topic in a 3D virtual environment and from a spatiotemporal perspective.We present the first 3D Eye-tracking Dataset for Visual Attention modeling in a virtual Museum,known as the EDVAM.In addition,a deep learning model is devised and tested with the EDVAM to predict a user’s subsequent visual attention from previous eye movements.This work provides a reference for visual attention modeling and context-aware interaction in the context of virtual museums.Yunzhan ZHOU Tian FENG Shihui SHUAI Xiangdong LI Lingyun SUN Henry Been-Lirn DUH 2022Frontiers of Information Technology & Electronic Engineering2022,23,1:0
2Atom Recombination of Difluorocarbene Enables 3-Fluorinated Oxindoles from 2-Aminoarylketones显示文摘Contrary to the traditional implementation as a difluoromethyl group and recently disclosed role of C1 synthons in synthetic organic chemistry,difluorocarbene(:CF_(2))is reported herein to proceed in unprecedented atom recombination as both a C1 synthon and F1 reagent simultaneously to render valuable 3-fluorinated oxindoles from 2-aminoarylketones.The reaction does not require catalyst and features a broad range of substrates with good functional group compatibility and ease of execution.This transformation could be employed to the quick-constructions of certain bioactive molecule derivatives.The mechanistic experiments and density functional theory(DFT)calculations indicate that this atom recombination reaction of:CF_(2) for the synthesis of 3-fluorinated oxindoles may involve a rearrangement process of epoxide intermediates.Guan Zhang Qianqian Shi Mengyuan Hou Kai Yang Shihui Wang Shuai Wang Wangyang Li Chaokun Li Jian Qiu Hetao Xu Lu Zhou Cece Wang Shi-Jun Li Yu Lan Qiuling Song 2022CCS Chemistry2022,4,5:0
