Rare events are processes that occur upon the emergence of unlikely fluctuations. Unlike
what their name suggests, rare events are fairly ubiquitous in nature, as the occurrence of …

We investigate the impact of community structure on information diffusion with the linear
threshold model. Our results demonstrate that modular structure may have counterintuitive …

In this work we study the opinion evolution in a community-based population with intergroup
interactions. We address two issues. First, we consider that such intergroup interactions can …

We construct and analyze a random graph model for discrete choice with social interaction
and several groups of equal size. We concentrate on the case of two groups of equal sizes …

Brain activity is characterized by brain-wide spatiotemporal patterns which emerge from
synapse-mediated interactions between individual neurons. Calcium imaging provides …

We investigate the phase transitions behavior of the majority-vote model with noise on a
topology that consists of two coupled random networks. A parameter p is used to measure …

We investigate opinion diffusion on complex networks and the interplay between the
existence of neutral opinion states and non-trivial network structures. For this purpose, we …

We report the results of the magnetisation reversal in Ising ferromagnet having thermal and
field gradients by Monte Carlo simulation. We have studied the distribution of reversal times …

The nucleation in Ising ferromagnet has been studied by Monte Carlo simulation. Here,
unlike the earlier studies, the magnetic field is spreading over the space in time. The …

We explore the cooperative behaviour and phase transitions of interacting networks by
studying a simplified model consisting of Ising spins placed on the nodes of two coupled …
