More people, more fun: The scaling of events in cities

  This is a recent article publish in by David Martín-Corral, Manuel Cebrián and myself in which we analyze the super-scaling of touristic attraction (number of events) with population. Amazingly we found that the number of events (music/theater/sports/etc.) scales super-linearly with the population of the city. So yes! more people means more fun!  


2015 year in review

2015 has been an amazing year both on the professional and personal grounds. Here are some of the main things that happened this year: I helped to build up the “Master in Data Science and Big Data in Finance” at the Afi School of Finance. In this first edition we had 18 incredible students and the support from most of the big...


Fully nonlinear dynamics of stochastic thin-film dewetting

S. Nesic, R. Cuerno, E. Moro, and L. Kondic Physical Review E 92, 061002(R) [LINK] [PDF] Summary: The spontaneous formation of droplets via dewetting of a thin fluid film from a solid substrate allows materials nanostructuring. Often, it is crucial to be able to control the evolution, and to produce patterns characterized by regularly spaced droplets. While thermal fluctuations are expected to...


Temporal networks with R and igraph (updated)

A while ago, I wrote a post about how to create animations of temporal networks using R and the amazing package igraph package. The post was written in 2012 and the code does not work with the most recent versions (1.0) of igraph. Here I revisited that post, improving its performance and also making it consistent with the new versions of...


Daily rhythms in mobile telephone communication

Talayeh Aledavood , Eduardo López, Sam G. B. Roberts, Felix Reed-Tsochas, Esteban Moro, Robin I. M. Dunbar, Jari Saramäki PLoS ONE 10(9), e0138098 [LINK] Summary: Circadian rhythms are known to be important drivers of human activity and the recent availability of electronic records of human behaviour has provided fine-grained data of temporal patterns of activity on a large scale. Further, questionnaire studies...


From Seconds to Months: multi-scale dynamics of mobile telephone calls

Jari Saramaki, Esteban Moro arXiv:1504.01479 [PDF] Summary: Big Data on electronic records of social interactions allow approaching human behaviour and sociality from a quantitative point of view with unforeseen statistical power. Mobile telephone Call Detail Records (CDRs), automatically collected by telecom operators for billing purposes, have proven especially fruitful for understanding one-to-one communication patterns as well as the dynamics of social...
