Discovering hierarchical governing equations for community-structured complex network dynamics with LLM agents
Jinlei Zhang, Zixuan Zhang, Hao Qiu +8
Governing equations provide an interpretable description of the mechanisms underlying complex network dynamics, yet their discovery from observational data remains challenging when…
Economic Distance Structures Urban Mobility in 109 U.S. Cities
Wei-Peng Nie, Xiao-Yong Yan, Bin Jia +4
Urban mobility promises social integration, yet daily movement is systematically constrained by socioeconomic hierarchies. Introducing "economic distance"--the continuous income ga…
Self-similarity of mobility networks
Ying-Yue Lyu, Xiao-Yong Yan, Bin Jia +3
Mobility systems of people and goods are inherently multi-scale, spanning levels of organization from individual cities to regions and nations. Understanding whether mobility netwo…
Scaling law of individual urban tour behavior
Xu-Jie Lin, Yitao Yang, Wei-Peng Nie +1
Analyzing and modeling the mobility process with tour behavior is fundamental to understanding a wide range of complex systems, including animal foraging, human mobility and freigh…
A generalized vector-field framework for mobility
Erjian Liu, Mattia Mazzoli, Xiao-Yong Yan +1
Trip flow between areas is a fundamental metric for human mobility research. Given its identification with travel demand and its relevance for transportation and urban planning, ma…
