Hierarchical route to the emergence of leader nodes in real-world networks
Joseph D. O'Brien, Kleber A. Oliveira, James P. Gleeson +1
A large number of complex systems, naturally emerging in various domains, are well described by directed networks, resulting in numerous interesting features that are absent from t…
Nonlinear walkers and efficient exploration of congested networks
Timoteo Carletti, Malbor Asllani, Duccio Fanelli +1
Random walks are the simplest way to explore or search a graph, and have revealed a very useful tool to investigate and characterize the structural properties of complex networks f…
The role of modularity in self-organisation dynamics in biological networks
Bram A. Siebert, Cameron L. Hall, James P. Gleeson +1
Interconnected ensembles of biological entities are perhaps some of the most complex systems that modern science has encountered so far. In particular, scientists have concentrated…
Indetermination of networks structure from the dynamics perspective
Malbor Asllani, Bruno Requiao da Cunha, Ernesto Estrada +1
Networks are universally considered as complex structures of interactions of large multi-component systems. In order to determine the role that each node has inside a complex netwo…
A universal route to pattern formation
Malbor Asllani, Timoteo Carletti, Duccio Fanelli +1
Self-organization, the ability of a system of microscopically interacting entities to shape macroscopically ordered structures, is ubiquitous in Nature. Spatio-temporal patterns ar…
Resilience for stochastic systems interacting via a quasi-degenerate network
Sara Nicoletti, Duccio Fanelli, Niccolò Zagli +6
A stochastic reaction-diffusion model is studied on a networked support. In each patch of the network two species are assumed to interact following a non-normal reaction scheme. Wh…
