Effect of risk perception on epidemic spreading in temporal networks
(American Chemical Society (ACS), 2018-01-31)
Article
Accés obertMany progresses in the understanding of epidemic spreading models have been obtained thanks to numerous modeling efforts and analytical and numerical studies, considering host populations with very different structures and ... -
Effects of heterogeneous social interactions on flocking dynamics
(2018-02-08)
Article
Accés obertSocial relationships characterize the interactions that occur within social species and may have an important impact on collective animal motion. Here, we consider a variation of the standard Vicsek model for collective ... -
Effects of local population structure in a reaction-diffusion model of a contact process on metapopulation networks
(2013-10-30)
Article
Accés obertWe investigate the effects of local population structure in reaction-diffusion processes representing a contact process (CP) on metapopulations represented as complex networks. Considering a model in which the nodes of a ... -
Effects of mobility on ordering dynamics
(2009-11)
Article
Accés restringit per política de l'editorialModels of ordering dynamics allow us to understand natural systems in which an initially disordered population homogenizes some traits via local interactions. The simplest of these models, with wide applications ranging ... -
Effects of temporal correlations in social multiplex networks
(Macmillan Publishers, 2017-08-17)
Article
Accés obertMulti-layered networks represent a major advance in the description of natural complex systems, and their study has shed light on new physical phenomena. Despite its importance, however, the role of the temporal dimension ... -
Eigenvector localization in real networks and its implications for epidemic spreading
(2018-02-10)
Article
Accés obertThe spectral properties of the adjacency matrix, in particular its largest eigenvalue and the associated principal eigenvector, dominate many structural and dynamical properties of complex networks. Here we focus on the ... -
Entropy of form and hierarchic organization
(1992)
Capítol de llibre
Accés restringit per decisió de l'autorThe use of the Theory of Information as a mathematical tool for the understanding of complex systems allows the application of the MaxEnt Principle as a criterion for the prediction of the final stationary states. The ... -
Epidemic dynamics and endemic states in complex networks
(2001-05-22)
Article
Accés obertWe study by analytical methods and large scale simulations a dynamical model for the spreading of epidemics in complex networks. In networks with exponentially bounded connectivity we recover the usual epidemic behavior ... -
Epidemic dynamics in finite size scale-free networks
(American Institute of Physics (AIP), 2002-03)
Article
Accés obertMany real networks present a bounded scale-free behavior with a connectivity cutoff due to physical constraints or a finite network size. We study epidemic dynamics in bounded scale-free networks with soft and hard ... -
Epidemic outbreaks in complex heterogeneous networks
(Springer, 2002-04)
Article
Accés obertWe present a detailed analytical and numerical study for the spreading of infections with acquired immunity in complex population networks. We show that the large connectivity fluctuations usually found in these networks ... -
Epidemic processes in complex networks
(2015-08-31)
Article
Accés obertIn recent years the research community has accumulated overwhelming evidence for the emergence of complex and heterogeneous connectivity patterns in a wide range of biological and sociotechnical systems. The complex ... -
Epidemic spreading in complex networks with degree correlations
(2003)
Capítol de llibre
Accés restringit per política de l'editorialWe review the behavior of epidemic spreading on complex networks in which there are explicit correlations among the degrees of connected vertices. -
Epidemic spreading in correlated complex networks
(2002-10)
Article
Accés obertWe study a dynamical model of epidemic spreading on complex networks in which there are explicit correlations among the node’s connectivities. For the case of Markovian complex networks, showing only correlations between ... -
Epidemic spreading in scale-free networks
(American Institute of Physics (AIP), 2001-04-02)
Article
Accés obertThe Internet has a very complex connectivity recently modeled by the class of scale-free networks. This feature, which appears to be very efficient for a communications network, favors at the same time the spreading of ... -
Epidemic thresholds of the susceptible-infected-susceptible model on networks: a comparison of numerical and theoretical results
(2012-10-15)
Article
Accés obertRecent work has shown that different theoretical approaches to the dynamics of the susceptible-infected-susceptible (SIS) model for epidemics lead to qualitatively different estimates for the position of the epidemic ... -
Epidemics and immunization in scale-free networks
(Wiley-VCH, 2003)
Capítol de llibre
Accés restringit per política de l'editorialComplex interacting networks are observed in systems from such diverse areas as physics, biology, economics, ecology, and computer science. For example, economic or social interactions often organize themselves in complex ... -
Evolution and structure of the internet: a statistical physics approach
(Cambridge University Press, 2004-02-28)
Llibre
Accés restringit per política de l'editorialThe talk will present an overview of the large-scale topological and dynamical properties of real Internet maps. First I will review the methodology used to obtain large scale maps of the Internet at the router and autonomous ... -
Evolution in a changing environment
(2013-01-10)
Article
Accés obertWe propose a simple model for genetic adaptation to a changing environment, describing a fitness landscape characterized by two maxima. One is associated with “specialist” individuals that are adapted to the environment; ... -
Evolutionary dynamics of the cryptocurrency market
(2017-11-15)
Article
Accés obertThe cryptocurrency market surpassed the barrier of $100 billion market capitalization in June 2017, after months of steady growth. Despite its increasing relevance in the financial world, a comprehensive analysis of the ... -
Evolving protein interaction networks through gene duplication
(2003-05-21)
Article
Accés obertThe topology of the proteome map revealed by recent large-scale hybridization methods has shown that the distribution of protein–protein interactions is highly heterogeneous, with many proteins having few edges while a few ...
