Collective cooperation without individual fidelity in LLM agents
Henrique Ferraz de Arruda, Carlos Gracia Lázaro, Alberto Aleta +1
Large language models (LLMs) are increasingly used as agents in simulations of social systems, yet it remains unclear when their behavior can be interpreted as a faithful proxy for…
Diversification of global food trade partners increased inequalities in the exposure to shock risks
Ariadna Fosch, Alberto Aleta, Roger Cremades +1
Recent global food trade disruptions have evidenced how local shocks can cascade into global security threats. While the capacity of food systems to absorb spillovers depends heavi…
Multilayer network science: theory, methods, and applications
Alberto Aleta, Andreia Sofia Teixeira, Guilherme Ferraz de Arruda +14
Multilayer network science has emerged as a central framework for analysing interconnected and interdependent complex systems. Its relevance has grown substantially with the increa…
Interplay between pitch control and top speed in soccer: The stamina factor
Marco F. da Silva, A. Novillo, A. Aleta +4
In this study, we investigate the interplay between player speed and ball control in soccer. We present a novel pitch control algorithm that quantifies the probability of a player…
Interplay of epidemic spreading and vaccine uptake under complex social contagion
Alfonso de Miguel-Arribas, Alberto Aleta, Yamir Moreno
Modeling human behavior is essential to accurately predict epidemic spread, with behaviors like vaccine hesitancy complicating control efforts. While epidemic spread is often treat…
Multilayer networks describing interactions in urban systems: a digital twin of five cities in Spain
Jorge P. Rodríguez, Alberto Aleta, Yamir Moreno
Networks specifying who interacts with whom are crucial for mathematical models of epidemic spreading. In the context of emerging diseases, these networks have the potential to enc…
Generative Agent-Based Models for Complex Systems Research: a review
Yikang Lu, Alberto Aleta, Chunpeng Du +2
The advent of Large Language Models (LLMs) has significantly transformed the fields of natural and social sciences. Generative Agent-Based Models (GABMs), which utilize large langu…
Contagion dynamics on higher-order networks
Guilherme Ferraz de Arruda, Alberto Aleta, Yamir Moreno
Understanding the dissemination of diseases, information, and behavior stands as a paramount research challenge in contemporary network and complex systems science. The COVID-19 pa…
Understanding the Vegetable Oil Debate and Its Implications for Sustainability through Social Media
Elena Candellone, Alberto Aleta, Henrique Ferraz de Arruda +2
The global production and consumption of vegetable oils have sparked several discussions on sustainable development. This study analyzes over 20 million tweets related to vegetable…
Characterising the role of human behaviour in the effectiveness of contact-tracing applications
Ariadna Fosch, Alberto Aleta, Yamir Moreno
Albeit numerous countries relied on contact-tracing (CT) applications as an epidemic control measure against the COVID-19 pandemic, the debate around their effectiveness is still o…
Ethics in rotten apples: A network epidemiology approach for active cyber defense
Francesco Bonacina, Ignacio Echegoyen, Diego Escribano +5
As Internet of Things (IoT) technology grows, so does the threat of malware infections. A proposed countermeasure, the use of benevolent "white worms" to combat malicious "black wo…
An informational approach to uncover the age group interactions in epidemic spreading from macro analysis
Tiago Martinelli, Alberto Aleta, Francisco A. Rodrigues +1
We investigate the use of transfer entropy (TE) as a proxy to detect the contact patterns of the population in epidemic processes. We first apply the measure to a classical age-str…
Digital cities and the spread of COVID-19: characterizing the impact of non-pharmaceutical interventions in five cities in Spain
Jorge P. Rodríguez, Alberto Aleta, Yamir Moreno
Mathematical modeling has been fundamental to achieving near real-time accurate forecasts of the spread of COVID-19. Similarly, the design of non-pharmaceutical interventions has p…
Epidemic spreading in populations of mobile agents with adaptive behavioral response
Paulo Cesar Ventura, Alberto Aleta, Francisco A. Rodrigues +1
Despite the advanced stage of epidemic modeling, there is a major demand for methods to incorporate behavioral responses to the spread of a disease such as social distancing and ad…
Modeling the effects of social distancing on the large-scale spreading of diseases
Paulo Cesar Ventura, Alberto Aleta, Francisco Aparecido Rodrigues +1
To contain the propagation of emerging diseases that are transmissible from human to human, non-pharmaceutical interventions (NPIs) aimed at reducing the interactions between human…
Prediction of scientific collaborations through multiplex interaction networks
Marta Tuninetti, Alberto Aleta, Daniela Paolotti +2
Link prediction algorithms can help to understand the structure and dynamics of scientific collaborations and the evolution of Science. However, available algorithms based on simil…
Data-driven contact structures: from homogeneous mixing to multilayer networks
Alberto Aleta, Guilherme Ferraz de Arruda, Yamir Moreno
The modeling of the spreading of communicable diseases has experienced significant advances in the last two decades or so. This has been possible due to the proliferation of data a…
