From motifs to Lévy flights: Modeling urban mobility in Bogotá's public transport system
Juan F. Alayón-MartÃnez, Alejandro P. Riascos
In this paper, we study two years of access card validation records from Bogotá's multimodal public transport system, comprising over 2.3 billion trips across bus rapid transit, f…
Dissimilarity measures for generalized Lotka-Volterra systems on networks
Nicolás A. Márquez, Maryam Chaib De Mares, Alejandro P. Riascos
In this paper, we introduce a general framework to quantify dissimilarities between generalized Lotka-Volterra dynamical processes, ranging from classical predator-prey systems to…
Mean first-encounter times of simultaneous random walkers with resetting on networks
Daniel Rubio-Gómez, Alejandro P. Riascos, José L. Mateos
We investigate the dynamics of simultaneous random walkers with resetting on networks and derive exact analytical expressions for the mean first-encounter times of Markovian random…
Random walks with long-range memory on networks
Ana Gabriela Guerrero-Estrada, Alejandro P. Riascos, Denis Boyer
We study an exactly solvable random walk model with long-range memory on arbitrary networks. The walker performs unbiased random steps to nearest-neighbor nodes and intermittently…
Antifragility of stochastic transport on networks with damage
L. K. Eraso-Hernandez, A. P. Riascos
A system is called antifragile when damage acts as a constructive element improving the performance of a global function. In this paper, we analyze the emergence of antifragility i…
