A waiting time based prediction strategy which exploits the local anticorrelation of large events is discussed. With this strategy we show analytically and numerically that large events are predictable, and that this predictability persists in the thermodynamic limit. We introduce another strategy which predicts large avalanches in the future based on the present excess density in the sandpile. We obtain the exact conditional probabilities for large events given an excess density, and use this to determine the exact form of the ROC predictability curves. We show that for this strategy, the model is predictable only for finite lattice sizes, and unpredictable in the thermodynamic limit.

However, in complex systems, chemical reactions are often coupled with physical diffusion processes, which have a significant impact on the reaction dynamics, rendering the classical chemical master equation inadequate. Moreover, the reaction and diffusion processes are typically nonhomogeneous, further altering the time evolution of the chemical dynamic process. In this paper we propose a chemical continuous time random walks under anomalous diffusion model based on the renewal process where the waiting times are arbitrary distributed. By applying this model, we obtain the generalizations of the chemical diffusion master equation, the mass action laws, the fluctuation-dissipation theorem in the closed system, and the Gillespie algorithm to describe the effects of physical diffusion and the heterogeneity of the system. As an example, we analyze the monomolecular reaction-diffusion system with exponential and power-law waiting times, respectively, and show the fractional memory effect of the average of the concentrations of reactants on its history. This work gives one approach to describe anomalous diffusion with any reaction, and provides the systematic stochastic theory for modeling the heterogeneous chemical diffusive system.</p></div>","PeriodicalId":667,"journal":{"name":"Journal of Statistical Physics","volume":"192 12","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145493465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
