Emergence of metapopulations and echo chambers in mobile agents
Starnini, Michele; Frasca, Mattia; Baronchelli, Andrea (Nature, 2016-08-30)
Article
Accés obertMulti-agent models often describe populations segregated either in the physical space, i.e. subdivided in metapopulations, or in the ecology of opinions, i.e. partitioned in echo chambers. Here we show how both kinds of ... -

Epidemic processes on self-propelled particles: Continuum and agent-based modeling
Rodríguez García, Jorge Pablo; Paoluzzi, Matteo; Levis, Demian; Starnini, Michele (American Physical Society, 2022-12-05)

Equivalence between Non-Markovian and Markovian Dynamics in Epidemic Spreading Processes
Gleeson, J P; Boguña Espinal, Marian; Starnini, Michele (American Institute of Physics (AIP), 2017-03-24)
Article
Accés obertA general formalism is introduced to allow the steady state of non-Markovian processes on networks to be reduced to equivalent Markovian processes on the same substrates. The example of an epidemic spreading process is ... -
Flocking-enhanced social contagion

Article
Accés obertBackground: Emergency Medical Services (EMS) plays a fundamental role in providing good quality healthcare services to citizens, as they are the first responders in distressing situations. Few studies have used available ... -
Generalized voter-like models on heterogeneous networks
Moretti, Paolo; Baronchelli, Andrea; Starnini, Michele; Pastor Satorras, Romualdo (Springer, 2013)
Capítol de llibre
Accés restringit per política de l'editorialThis Chapter presents a generalized model of consensus formation, which is able to encompass all previous formulations of copy/invasion processes inspired by variations on the voter model and the Moran process. It considered ... -
Geometric randomization of real networks with prescribed degree sequence
Starnini, Michele; ortiz, elisenda; Serrano, M.Angels (2019-05-01)
Article
Accés obertWe introduce a model for the randomization of complex networks with geometric structure. The geometric randomization (GR) model assumes a homogeneous distribution of the nodes in a hidden similarity space and uses rewirings ... -
Global misinformation spillovers in the vaccination debate before and during the COVID-19 pandemic: multilingual Twitter study
Lenti, Jacopo; Mejova, Yelena; Kalimeri, Kyriaki; Panisson, André; Paolotti, Daniela; Tizzani, Michele; Starnini, Michele (2023-01-01)
Article
Accés obertBackground: Antivaccination views pervade online social media, fueling distrust in scientific expertise and increasing the number of vaccine-hesitant individuals. Although previous studies focused on specific countries, ... -
Immunization strategies for epidemic processes in time-varying contact networks
Starnini, Michele; Machens, Anna; Cattuto, Ciro; Barrat, Alain; Pastor Satorras, Romualdo (2013)
Article
Accés obertpreading processes represent a very efficient tool to investigate the structural properties of networks and the relative importance of their constituents, and have been widely used to this aim in static networks. Here we ... -
Impact of data accuracy on the evaluation of COVID-19 mitigation policies
Starnini, Michele; Aleta, Alberto; Tizzoni, Michele; Moreno, Yamir (Cambridge University Press, 2021-10-28)
Article
Accés obertEvaluating the effectiveness of nonpharmaceutical interventions (NPIs) to mitigate the COVID-19 pandemic is crucial to maximize the epidemic containment while minimizing the social and economic impact of these measures. ... -
