Open AccessEndemic infectious states below the epidemic threshold and beyond herd immunity
The COVID-19 pandemic exhibits intertwined epidemic waves with anomalous fade-outs characterized by persistent low prevalence. These long-living epidemic states complicate epidemic control and challenge curren...

Open AccessEcho chambers and information transmission biases in homophilic and heterophilic networks
We study how information transmission biases arise by the interplay between the structural properties of the network and the dynamics of the information in synthetic scale-free homophilic/heterophilic networks...

Open AccessImpact of urban structure on infectious disease spreading
The ongoing SARS-CoV-2 pandemic has been holding the world hostage for several years now. Mobility is key to viral spreading and its restriction is the main non-pharmaceutical interventions to fight the virus ...

Open AccessAn ecological approach to structural flexibility in online communication systems
Human cognitive abilities are limited resources. Today, in the age of cheap information—cheap to produce, to manipulate, to disseminate—this cognitive bottleneck translates into hypercompetition for rewarding ...

Open AccessExplore with caution: map** the evolution of scientific interest in physics
In the book The Essential Tension (1979) Thomas Kuhn described the conflict between tradition and innovation in scientific research—i.e., the desire to explore new promising areas, counterposed to the need to cap...

Open AccessImpact of origin-destination information in epidemic spreading
The networked structure of contacts shapes the spreading of epidemic processes. Recent advances on network theory have improved our understanding of the epidemic processes at large scale. The relevance of seve...

Open AccessA Multilayer perspective for the analysis of urban transportation systems
Public urban mobility systems are composed by several transportation modes connected together. Most studies in urban mobility and planning often ignore the multi-layer nature of transportation systems consider...

Open AccessCharacterising two-pathogen competition in spatially structured environments
Different pathogens spreading in the same host population often generate complex co-circulation dynamics because of the many possible interactions between the pathogens and the host immune system, the host lif...

Open AccessImpact of Social Punishment on Cooperative Behavior in Complex Networks
Social punishment is a mechanism by which cooperative individuals spend part of their resources to penalize defectors. In this paper, we study the evolution of cooperation in 2-person evolutionary games on net...

Emergence of Influential Spreaders in Modified Rumor Models
The burst in the use of online social networks over the last decade has provided evidence that current rumor spreading models miss some fundamental ingredients in order to reproduce how information is dissemin...

Modeling Epidemic Spreading in Complex Networks: Concurrency and Traffic
The study of complex networks sheds light on the relation between the structure and function of complex systems. One remarkable result is the absence of an epidemic threshold in infinite-size scale-free networ...

Open AccessModeling human mobility responses to the large-scale spreading of infectious diseases
Current modeling of infectious diseases allows for the study of realistic scenarios that include population heterogeneity, social structures and mobility processes down to the individual level. The advances in...

Soft Computing Techniques for Internet Backbone Traffic Anomaly Detection
The detection of anomalies and faults is a fundamental task for different fields, especially in real cases like LAN networks and the Internet. We present an experimental study of anomaly detection on a simulat...
