Universal roughness and the dynamics of urban expansion
Ulysse Marquis, Oriol Artime, Riccardo Gallotti +1
Urban sprawl reshapes cities, yet its quantitative laws remain elusive. Analyzing built-up expansion in 19 cities (1985-2015) with tools from surface growth physics in radial geome…
Multilayer Network Science: from Cells to Societies
Oriol Artime, Barbara Benigni, Giulia Bertagnolli +5
Networks are convenient mathematical models to represent the structure of complex systems, from cells to societies. In the past decade, multilayer network science -- the branch of…
The connection between the spread of misinformation, time of day, and individual user activity patterns
Elisabeth Stockinger, Riccardo Gallotti, Carina I. Hausladen
Social media manipulation poses a significant threat to cognitive autonomy and unbiased opinion formation. Prior literature explored the relationship between online activity and em…
Analysis of COVID-19 first wave in the US based on demographic, mobility, and environmental variables
Dario Spiller, Gabriele Santin, Alessandro Sebastianelli +6
COVID-19 had a strong and disruptive impact on our society, and yet further analyses on most relevant factors explaining the spread of the pandemic are needed. Interdisciplinary st…
Emergence of complex network topologies from flow-weighted optimization of network efficiency
Sebastiano Bontorin, Giulia Cencetti, Riccardo Gallotti +2
Transportation and distribution networks are a class of spatial networks that have been of interest in recent years. These networks are often characterized by the presence of compl…
The distorting lens of human mobility data
Riccardo Gallotti, Davide Maniscalco, Marc Barthelemy +1
The description of complex human mobility patterns is at the core of many important applications ranging from urbanism and transportation to epidemics containment. Data about colle…
The voice of few, the opinions of many: evidence of social biases in Twitter COVID-19 fake news sharing
Piergiorgio Castioni, Giulia Andrighetto, Riccardo Gallotti +2
Online platforms play a relevant role in the creation and diffusion of false or misleading news. Concerningly, the COVID-19 pandemic is shaping a communication network - barely con…
Living in a pandemic: adaptation of individual mobility and social activity in the US
Lorenzo Lucchini, Simone Centellegher, Luca Pappalardo +4
The non-pharmaceutical interventions (NPIs), aimed at reducing the diffusion of the COVID-19 pandemic, has dramatically influenced our behaviour in everyday life. In this work, we…
Effectiveness of dismantling strategies on moderated vs. unmoderated online social platforms
Oriol Artime, Valeria d'Andrea, Riccardo Gallotti +2
Online social networks are the perfect test bed to better understand large-scale human behavior in interacting contexts. Although they are broadly used and studied, little is known…
Assessing the risks of "infodemics" in response to COVID-19 epidemics
Riccardo Gallotti, Francesco Valle, Nicola Castaldo +2
Our society is built on a complex web of interdependencies whose effects become manifest during extraordinary events such as the COVID-19 pandemic, with shocks in one system propag…
Quantifying efficient information exchange in real network flows
Giulia Bertagnolli, Riccardo Gallotti, Manlio De Domenico
Network science enables the effective analysis of real interconnected systems, characterized by a complex interplay between topology and interconnections strength. It is well-known…
Unraveling the hidden organisation of urban systems and their mobility flows
Riccardo Gallotti, Giulia Bertagnolli, Manlio De Domenico
Increasing evidence suggests that cities are complex systems, with structural and dynamical features responsible for a broad spectrum of emerging phenomena. Here we use a unique da…
Scaling in the recovery of urban transportation systems from special events
Aleix Bassolas, Riccardo Gallotti, Fabio Lamanna +2
Public transportation is a fundamental infrastructure for the daily mobility in cities. Although its capacity is prepared for the usual demand, congestion may rise when huge crowds…
A quantitative description of the transition between intuitive altruism and rational deliberation in iterated Prisoner's Dilemma experiments
Riccardo Gallotti, Jelena Grujic
What is intuitive: pro-social or anti-social behaviour? To answer this fundamental question, recent studies analyse decision times in game theory experiments under the assumption t…
How ants move: individual and collective scaling properties
Riccardo Gallotti, Dante R. Chialvo
The motion of social insects is often used a paradigmatic example of complex adaptive dynamics arising from decentralized individual behavior. In this paper we revisit the topic of…
Tracking random walks
Riccardo Gallotti, Rémi Louf, Jean-Marc Luck +1
In empirical studies of random walks, continuous trajectories of animals or individuals are usually sampled over a finite number of points in space and time. It is however unclear…
A stochastic model of randomly accelerated walkers for human mobility
Riccardo Gallotti, Armando Bazzani, Sandro Rambaldi +1
The recent availability of large databases allows to study macroscopic properties of many complex systems. However, inferring a model from a fit of empirical data without any knowl…
The Multilayer Temporal Network of Public Transport in Great Britain
Riccardo Gallotti, Marc Barthelemy
Despite the widespread availability of information concerning Public Transport from different sources, it is extremely hard to have a complete picture, in particular at a national…
Anatomy and efficiency of urban multimodal mobility
Riccardo Gallotti, Marc Barthelemy
The growth of transportation networks and their increasing interconnections, although positive, has the downside effect of an increasing complexity which make them difficult to use…
Statistical Laws in Urban Mobility from microscopic GPS data in the area of Florence
Armando Bazzani, Bruno Giorgini, Sandro Rambaldi +2
The application of Statistical Physics to social systems is mainly related to the search for macroscopic laws, that can be derived from experimental data averaged in time or space,…
