Anomalous Lifshitz dimension in hierarchical networks of brain connectivity
Samaneh Esfandiary, Ali Safari, Jakob Renner +2
The spectral dimension is a generalization of the Euclidean dimension and quantifies the propensity of a network to transmit and diffuse information. We show that, in hierarchical-…
Persistence of hierarchical network organization and emergent topologies in models of functional connectivity
Ali Safari, Paolo Moretti, Ibai Diez +2
Functional networks provide a topological description of activity patterns in the brain, as they stem from the propagation of neural activity on the underlying anatomical or struct…
Graph theoretical approaches for the characterization of damage in hierarchical materials
Paolo Moretti, Jakob Renner, Ali Safari +1
We discuss the relevance of methods of graph theory for the study of damage in simple model materials described by the random fuse model. While such methods are not commonly used w…
Avalanche precursors of failure in hierarchical fuse networks
Paolo Moretti, Bastien Dietemann, Michael Zaiser
We study precursors of failure in hierarchical random fuse network models which can be considered as idealizations of hierarchical (bio)materials where fibrous assemblies are held…
Topological dimension tunes activity patterns in hierarchical modular network models
Ali Safari, Paolo Moretti, Miguel A. Muñoz
Connectivity patterns of relevance in neuroscience and systems biology can be encoded in hierarchical modular networks (HMNs). Moreover, recent studies highlight the role of hierar…
Griffiths phases and the stretching of criticality in brain networks
Paolo Moretti, Miguel A. Muñoz
Hallmarks of criticality, such as power-laws and scale invariance, have been empirically found in cortical networks and it has been conjectured that operating at criticality entail…
