Synthetic populations for epidemic, demographic and mobility modeling
Davide Torre, Miguel Artigues, Benjamin Faucher +7
Synthetic populations are essential for individual-based simulations, such as agent-based models, enabling the evaluation of policy interventions for epidemic control, demographic…
Mobility energetic balance frames spatial configuration of cities
Federico Bellisardi, Enrique Cano-Suñén, Ana Ruiz-Varona +1
Urban spatial configurations emerge as the result of interactions between citizens' activities, movements and the landscape. Topography forms part of the physical settings through…
Vector field theory in motion: Revealing latent potentials in soccer dynamics
Paula Rodríguez-Sánchez, Roberto López del Campo, Ricardo Resta +3
Team sports offer a natural laboratory for studying collective motion in competitive environments. While recent tracking technologies enabled detailed analysis of player and ball t…
Exploring the spatial segmentation of housing markets from online listings
David Abella, Johann H. Martínez, Mattia Mazzoli +6
The real estate market shows an inherent connection to space. Real estate agencies unevenly operate and specialize across space, price and type of properties, thereby segmenting th…
Critical mobility in policy making for epidemic containment
Jesús A. Moreno López, Sandro Meloni, Jose J. Ramasco
When considering airborne epidemic spreading in social systems, a natural connection arises between mobility and epidemic contacts. As individuals travel, possibilities to encounte…
A generalized vector-field framework for mobility
Erjian Liu, Mattia Mazzoli, Xiao-Yong Yan +1
Trip flow between areas is a fundamental metric for human mobility research. Given its identification with travel demand and its relevance for transportation and urban planning, ma…
Ordering dynamics and aging in the Symmetrical Threshold model
David Abella, Juan Carlos González-Avella, Maxi San Miguel +1
The so-called Granovetter-Watts model was introduced to capture a situation in which the adoption of new ideas or technologies requires a certain redundancy in the social environme…
When Dialects Collide: How Socioeconomic Mixing Affects Language Use
Thomas Louf, José J. Ramasco, David Sánchez +1
The socioeconomic background of people and how they use standard forms of language are not independent, as demonstrated in various sociolinguistic studies. However, the extent to w…
Biased versus unbiased numerical methods for stochastic simulations
Javier Aguilar, Jose J. Ramasco, Raúl Toral
Approximate numerical methods are one of the most used strategies to extract information from many-interacting-agents systems. In particular, numerical approximations are of extend…
Aging in binary-state models: The Threshold model for Complex Contagion
David Abella, Maxi San Miguel, José J. Ramasco
Binary-state models are those in which the constituent elements can only appear in two possible configurations. These models are fundamental in the mathematical treatment of a numb…
Endemic infectious states below the epidemic threshold and beyond herd immunity
Javier Aguilar, Beatriz Arregui García, Raúl Toral +2
In the recent COVID-19 pandemic we assisted at a sequence of epidemic waves intertwined by anomalous fade-outs with periods of low but persistent epidemic prevalence. These long-li…
Aging effects in Schelling Segregation model
David Abella, Maxi San Miguel, José J. Ramasco
The Schelling model has become a paradigm in social sciences to explain the emerge of residential spatial segregation even in the presence of high tolerance to mixed neighborhoods…
Some recent advances in urban system science: models and data
Elsa Arcaute, Jose J. Ramasco
Cities are characterized by the presence of a dense population with a high potential for interactions between individuals of diverse backgrounds. They appear in parallel to the Neo…
Capturing the diversity of multilingual societies
Thomas Louf, David Sanchez, Jose J. Ramasco
Cultural diversity encoded within languages of the world is at risk, as many languages have become endangered in the last decades in a context of growing globalization. To preserve…
The world-wide waste web
Johann H. Martínez, Sergi Romero, José J. Ramasco +1
Countries globally trade with tons of waste materials every year, some of which are highly hazardous. This trade admits a network representation of the world-wide waste web, with c…
Uncovering the socioeconomic facets of human mobility
Hugo Barbosa, Surendra Hazarie, Brian Dickinson +6
Given the rapid recent trend of urbanization, a better understanding of how urban infrastructure mediates socioeconomic interactions and economic systems is of vital importance. Wh…
Impact of urban structure on infectious disease spreading
Javier Aguilar, Aleix Bassolas, Gourab Ghoshal +8
The ongoing SARS-CoV-2 pandemic has been holding the world hostage for more than a year now. Mobility is key to viral spreading and its restriction is the main non-pharmaceutical i…
On the importance of trip destination for modeling individual human mobility patterns
Maxime Lenormand, Juan Murillo Arias, Maxi San Miguel +1
Getting insights on human mobility patterns and being able to reproduce them accurately is of the utmost importance in a wide range of applications from public health, to transport…
Field theory for recurrent mobility
Mattia Mazzoli, Alex Molas, Aleix Bassolas +3
Understanding human mobility is crucial for applications such as forecasting epidemic spreading, planning transport infrastructure and urbanism in general. While, traditionally, mo…
Migrant mobility flows characterized with digital data
Mattia Mazzoli, Boris Diechtiareff, Antonia Tugores +4
Monitoring migration flows is crucial to respond to humanitarian crisis and to design efficient policies. This information usually comes from surveys and border controls, but timel…
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…
Herding and idiosyncratic choices: Nonlinearity and aging-induced transitions in the noisy voter model
Oriol Artime, Adrián Carro, Antonio F. Peralta +3
We consider the herding to non-herding transition caused by idiosyncratic choices or imperfect imitation in the context of the Kirman Model for financial markets, or equivalently t…
