Autor: Min, Byungjoon; San Miguel, Maxi
Resumen: We study the coevolutionary dynamics of network topology and social complex contagion using a threshold cascade model. Our coevolving threshold model incorporates two mechanisms: the threshold mechanism for the spreading of a minority state such as a new opinion, idea, or innovation and the network plasticity implemented as rewiring of links to cut the connections between nodes in different states. Using numerical simulations and a mean-field theoretical analysis, we demonstrate that the coevolutionary dynamics can significantly affect the cascades dynamics. The domain of parameters, i.e., threshold and network mean degree, for which global cascades occur shrinks with increasing network plasticity, indicating that the rewiring process suppresses the onset of global cascades. We also found that during evolution, non-adopted nodes form denser connections, resulting in a wider degree distribution and a non-monotonous dependence of cascades sizes with plasticity.2024-03-28T11:42:43ZThreshold Cascade Dynamics in Coevolving NetworksMin, ByungjoonSan Miguel, Maxihttp://hdl.handle.net/10261/3521962024-03-28T11:38:00Z2024-03-28T11:38:00ZTítulo: Threshold Cascade Dynamics in Coevolving Networks

Resumen: We argue that theories and methods drawn from complexity science are urgently needed to guide the development and use of digital twins for cities. The theoretical framework from complexity science takes into account both the short-term and the long-term dynamics of cities and their interactions. This is the foundation for a new approach that treats cities not as large machines or logistic systems but as mutually interwoven self-organizing phenomena, which evolve, to an extent, like living systems.2024-03-28T11:28:04ZThe physics of languagesPatriarca, MarcoHeinsalu, ElsSánchez, Davidhttp://hdl.handle.net/10261/3521922024-03-28T11:15:19Z2024-03-28T11:15:18ZTítulo: The physics of languages

Resumen: Much like biological species, languages spread, evolve, compete and even go extinct. To understand these mechanisms, physicists are applying their methods to linguistics, creating the interdisciplinary field of language dynamics, as Marco Patriarca, Els Heinsalu and David Sánchez explain.2024-03-28T11:15:18Z
