Influence of scanning plane on Human Spinal Cord functional Magnetic Resonance echo planar imaging
Marta Moraschi, Silvia Tommasin, Laura Maugeri +11
BACKGROUND: Functional Magnetic Resonance Imaging (fMRI) is based on the Blood Oxygenation Level Dependent contrast and has been exploited for the indirect study of the neuronal ac…
Noise-cleaning the precision matrix of fMRI time series
Miguel Ibáñez-Berganza, Carlo Lucibello, Francesca Santucci +2
We present a comparison between various algorithms of inference of covariance and precision matrices in small datasets of real vectors, of the typical length and dimension of human…
Evidence of scale-free clusters of vegetation in tropical rainforests
Pablo Villegas, Tommaso Gili, Guido Caldarelli +1
Tropical rainforests exhibit a rich repertoire of spatial patterns emerging from the intricate relationship between the microscopic interaction between species. In particular, the…
Multi-scale Laplacian community detection in heterogeneous networks
Pablo Villegas, Andrea Gabrielli, Anna Poggialini +1
Heterogeneous and complex networks represent intertwined interactions between real-world elements or agents. Determining the multi-scale mesoscopic organization of clusters and int…
Characterizing spatial point processes by percolation transitions
Pablo Villegas, Tommaso Gili, Andrea Gabrielli +1
A set of discrete individual points located in an embedding continuum space can be seen as percolating or non-percolating, depending on the radius of the discs/spheres associated w…
Laplacian Renormalization Group for heterogeneous networks
Pablo Villegas, Tommaso Gili, Guido Caldarelli +1
The renormalization group is the cornerstone of the modern theory of universality and phase transitions, a powerful tool to scrutinize symmetries and organizational scales in dynam…
Laplacian paths in complex networks: information core emerges from entropic transitions
Pablo Villegas, Andrea Gabrielli, Francesca Santucci +2
Complex networks usually exhibit a rich architecture organized over multiple intertwined scales. Information pathways are expected to pervade these scales reflecting structural ins…
Emergent spatial patterns of coexistence in species-rich plant communities
Pablo Villegas, Tommaso Gili, Guido Caldarelli
Statistical Physics has proved essential to analyze multi-agent environments. Motivated by the empirical observation of various non-equilibrium features in Barro Colorado and other…
The unbalanced reorganization of weaker functional connections induces the altered brain network topology in schizophrenia
Rossana Mastrandrea, Fabrizio Piras, Andrea Gabrielli +4
Network neuroscience shed some light on the functional and structural modifications occurring to the brain associated with the phenomenology of schizophrenia. In particular, restin…
Altered Modularity and Disproportional Integration in Functional Networks are Markers of Abnormal Brain Organization in Schizophrenia
M. Cinelli, I. Echegoyen, M. Oliveira +2
Modularity plays an important role in brain networks' architecture and influences its dynamics and the ability to integrate and segregate different modules of cerebral regions. Alt…
Organization and hierarchy of the human functional brain network lead to a chain-like core
Rossana Mastrandrea, Andrea Gabrielli, Fabrizio Piras +3
The brain is a paradigmatic example of a complex system as its functionality emerges as a global property of local mesoscopic and microscopic interactions. Complex network theory a…
