When higher-order interactions matter: reducibility, parsimony, and microscopic organization
Alex Arenas, Federico Battiston, Andrea Gabrielli
The current debate on higher-order interactions raises a fundamental question: when can systems organized through group interactions be faithfully represented within a graph-based…
Towards a Theory for the Formation of Chimera Patterns in Complex Networks
Malbor Asllani, Alex Arenas
Chimera states, marked by the coexistence of order and disorder in systems of coupled oscillators, have captivated researchers with their existence and intricate patterns. Despite…
Exploring Spatial Segregation Induced by Competition Avoidance as Driving Mechanism for Emergent Coexistence in Microbial Communities
Mattia Mattei, Alex Arenas
This study investigates the role of spatial segregation, prompted by competition avoidance, as a key mechanism for emergent coexistence within microbial communities. Recognizing th…
Pattern formation and bifurcation analysis of delay induced fractional-order epidemic spreading on networks
Jiaying Zhou, Yong Ye, Alex Arenas +2
The spontaneous emergence of ordered structures, known as Turing patterns, in complex networks is a phenomenon that holds potential applications across diverse scientific fields, i…
A triadic approximation reveals the role of interaction overlap on the spread of complex contagions on higher-order networks
Giulio Burgio, Sergio Gómez, Alex Arenas
Contagion processes relying on the exposure to multiple sources are prevalent in social systems, and are effectively represented by hypergraphs. In this Letter, we derive a mean-fi…
Diffusion and synchronization dynamics reveal the multi-scale patterns of spatial segregation
Aleix Bassolas, Sergio Gómez, Alex Arenas
Urban systems are characterized by populations with heterogeneous characteristics, and whose spatial distribution is crucial to understand inequalities in life expectancy or educat…
A link model approach to identify congestion hotspots
Aleix Bassolas, Sergio Gómez, Alex Arenas
Congestion emerges when high demand peaks put transportation systems under stress. Understanding the interplay between the spatial organization of demand, the route choices of citi…
The political economy of big data leaks: Uncovering the skeleton of tax evasion
Pier Luigi Sacco, Alex Arenas, Manlio De Domenico
After the leak of 11.5 million documents from the Panamanian corporation Mossack Fonseca, an intricate network of offshore business entities has been revealed. The emerging picture…
The impact of inter-city mobility on urban welfare
Sayat Mimar, David Soriano-Paños, Alec Kirkley +5
While much effort has been devoted to understand the role of intra-urban characteristics on sustainability and growth, much remains to be understood about the effect of inter-urban…
Homophily impacts the success of vaccine roll-outs
Giulio Burgio, Benjamin Steinegger, Alex Arenas
Physical contacts do not occur randomly, rather, individuals with similar socio-demographic and behavioural characteristics are more likely to interact among them, a phenomenon kno…
Emergence of protective behaviour under different risk perceptions to disease spreading
Mozhgan Khanjanianpak, Nahid Azimi-Tafreshi, Alex Arenas +1
The behaviour of individuals is a main actor in the control of the spread of a communicable disease and, in turn, the spread of an infectious disease can trigger behavioural change…
The impact of homophily on digital proximity tracing
Giulio Burgio, Benjamin Steinegger, Giacomo Rapisardi +1
We study how homophily of human physical interactions affects the efficacy of digital proximity tracing. Analytical results show a non monotonous dependence of the reproduction num…
Infectious disease dynamics in metapopulations with heterogeneous transmission and recurrent mobility
Wesley Cota, David Soriano-Paños, Alex Arenas +2
Human mobility, contact patterns, and their interplay are key aspects of our social behavior that shape the spread of infectious diseases across different regions. In the light of…
Impact of origin-destination information in epidemic spreading
Sergio Gómez, Alberto Fernández, Sandro Meloni +1
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…
A framework for epidemic spreading in multiplex networks of metapopulations
David Soriano-Paños, Laura Lotero, Jesús Gómez-Gardeñes +1
We propose a theoretical framework for the study of epidemics in structured metapopulations, with heterogeneous agents, subjected to recurrent mobility patterns. We propose to repr…
Untangling the role of diverse social dimensions in the diffusion of microfinance
Elisa Omodei, Alex Arenas
Ties between individuals on a social network can represent different dimensions of interactions, and the spreading of information and innovations on these networks could potentiall…
Functional Multiplex PageRank
Jacopo Iacovacci, Christoph Rahmede, Alex Arenas +1
Recently it has been recognized that many complex social, technological and biological networks have a multilayer nature and can be described by multiplex networks. Multiplex netwo…
Detection of timescales in evolving complex systems
Richard K. Darst, Clara Granell, Alex Arenas +3
Most complex systems are intrinsically dynamic in nature. The evolution of a dynamic complex system is typically represented as a sequence of snapshots, where each snapshot describ…
Quantifying the Diaspora of Knowledge in the Last Century
Manlio De Domenico, Elisa Omodei, Alex Arenas
Academic research is driven by several factors causing different disciplines to act as "sources" or "sinks" of knowledge. However, how the flow of authors' research interests -- a…
Decongestion of urban areas with hotspot-pricing
Albert Solé-Ribalta, Sergio Gómez, Alex Arenas
The rapid growth of population in urban areas is jeopardizing the mobility and air quality worldwide. One of the most notable problems arising is that of traffic congestion which i…
Information transfer in community structured multiplex networks
Albert Solé-Ribalta, Clara Granell, Sergio Gómez +1
The study of complex networks that account for different types of interactions has become a subject of interest in the last few years, specially because its representational power…
Layer-layer competition in multiplex complex networks
Jesús Gómez-Gardeñes, Manlio De Domenico, Gerardo Gutiérrez +2
The coexistence of multiple types of interactions within social, technological and biological networks has moved the focus of the physics of complex systems towards a multiplex des…
Enhancing the stability of the synchronization of multivariable coupled oscillators
R. Sevilla-Escoboza, R. Gutiérrez, G. Huerta-Cuellar +4
