“悲剧”与“现代性”通常被视为两个互不相干的概念，前者泛指展现人间苦难的文学作品，后者标识人类文明演变的最新阶段，但在20世纪初期和中期，有不少中外学者曾在这两者之间做出因果连接。乔治·斯坦纳及其追随者认为，现代社会崇尚科学理性，导致悲剧艺术在17世纪之后一蹶不振；胡适和许多同时代其他学人则将现代性在中国姗姗来迟部分归咎于悲剧的缺失。拨开历史的迷雾，我们现在可以清晰地看到，这两个论断其实都站不住脚，因为它们基于过分狭隘的悲剧定义，而且错误地坚持悲剧的凄惨结局不可或缺。

Satellite-assisted 6G wide-area edge intelligence:dynamics-aware task offloading and resource allocation for remote IoT services

引用

Science China(Information Sciences) 2025年第2期68卷 248-268页

作者： Di ZHAO Rui ding Bin SONG State Key Laboratory of Integrated Services Networks Xidian University Hangzhou Institute of Technology Xidian University China Satellite Network Group Co. Ltd.

Future 6G networks will integrate non-terrestrial communication with mobile edge computing to enable wide-area edge intelligence, providing ubiquitous communication and computation services for everyone and everything. In this paper, we introduce the intelligent cloud-edge-device architecture into low Earth orbit(LEO) satellite-supported remote Internet of Things(IoT) networks to facilitate latency-sensitive and compute-intensive IoT applications. However, the dynamic spatio-temporal characteristics inherent in LEO satellite networks, such as the high volatility of task traffic and the high mobility of space nodes, pose severe challenges. For efficient task execution, we investigate the joint optimization of cross-region task offloading and cross-domain resource allocation, and innovatively propose a spatio-temporal attention-based proximal policy optimization(STA-PPO) algorithm. Specifically, the temporal attention-based actor network analyzes the timing dependencies of task arrival and makes time-variant decisions. Simultaneously, the spatial attention-based critic network captures the spatial variations of satellite motion and evaluates the topology-related value. We verify the effectiveness of the cloud-edge-device collaboration through extensive simulations. Numerical results demonstrate that the STA-PPO algorithm outperforms benchmarks, showing the lowest system delay and the highest link throughput.

Benchmarking model chemistry composite calculations for vertical ionization potential of molecular systems

Chinese Chemical Letters 2025年第2期36卷 536-539页

作者： Bingwei Wang Yihong ding Xiao Tian Key Laboratory of Carbon Materials of Zhejiang Province Wenzhou Key Lab of Advanced Energy Storage and Conversion Zhejiang Province Key Lab of Leather Engineering College of Chemistry and Materials Engineering Wenzhou University Laboratory of Theoretical and Computational Chemistry Institute of Theoretical Chemistry Jilin University School of Mathematics and Science Hebei GEO University

In chemical science, the vertical ionization potential(VIP) is a crucial metric for understanding the electronegativity, hardness and softness of chemical material systems as well as the electronic structure and stability of molecules. Ever since the last century, the model chemistry composite methods have witnessed tremendous developments in computing the thermodynamic properties as well as the barrier heights. However, their performance in realm of the vertical electron processes of molecular systems has been rarely explored. In this study, we for the first time benchmarked the model chemistry composite methods(e.g., CBS-QB3, G4 and W1BD) in comparison with the commonly used Koopmans' s theorem(KT), electron propagator theory(e.g., OVGF, D2, P3 and P3+) and CCSD(T) methods in calculating the VIP for up to 613 molecular systems with available experimental measurements. The large-scale test calculations strongly showed that the CBS-QB3 model chemistry composite technique can be well recommended to calculate VIP from the perspectives of accuracy, economy and applicability. Notably, the VIP values of up to 7 molecules were identified to have the absolute errors of larger than 0.3 e V at all calculation levels,which have strong hints that their VIP experimental values should be re-investigated.
