Branching Process Approach to Avalanche Dynamics on Complex Networks
We investigate the avalanche dynamics of the Bak-Tang-Wiesenfeld (BTW) sandpile model on complex networks with general degree distributions. With the threshold height of each node given as its degree in the model, self-organized criticality emerges such that the avalanche size and the duration distribution follow power laws with exponents τ and δ, respectively. Applying the theory of the multip...
متن کاملSandpile avalanche dynamics on scale-free networks
Avalanche dynamics is an indispensable feature of complex systems. Here, we study the self-organized critical dynamics of avalanches on scale-free networks with degree exponent through the Bak–Tang–Wiesenfeld (BTW) sandpile model. The threshold height of a node i is set as k1− i with 06 ¡ 1, where ki is the degree of node i. Using the branching process approach, we obtain the avalanche size and...
متن کاملBranching process approach for Boolean bipartite networks of metabolic reactions.
The branching process (BP) approach has been successful in explaining the avalanche dynamics in complex networks. However, its applications are mainly focused on unipartite networks, in which all nodes are of the same type. Here, motivated by a need to understand avalanche dynamics in metabolic networks, we extend the BP approach to a particular bipartite network composed of Boolean AND and OR ...
متن کاملA First Approach to Belief Dynamics in Complex Social Networks
Many people today participate in more than one social network on a daily basis; such networks can be seen as dynamic environments containing knowledge about their members. From a KR perspective, these environments are complex in many dimensions; for instance, it is not clear how to treat news being communicated through the network, especially when it contradicts a user’s own knowledge, or when ...
متن کاملSpreading dynamics on complex networks: a general stochastic approach.
Dynamics on networks is considered from the perspective of Markov stochastic processes. We partially describe the state of the system through network motifs and infer any missing data using the available information. This versatile approach is especially well adapted for modelling spreading processes and/or population dynamics. In particular, the generality of our framework and the fact that it...
