Epistatic strength, modularity, and locus heterogeneity shape the number of local optima in fitness landscapes
Mahan Ghafari, Alejandro Castro Cabrera, Alejandro Lage-Castellanos +3
Fitness landscapes provide a quantitative framework for understanding how natural selection shapes evolutionary trajectories. A central feature of these landscapes is their number…
Simple sign epistasis and evolutionary detours in fitness landscapes
Paolo Ribeca, Alejandro Castro, Alejandro Lage-Castellanos +8
In epistatic fitness landscapes, the fitness effect of a mutation depends on the genetic background and may even switch between deleterious and beneficial depending on the presence…
From informal markets to Limit Order Book dynamics: a mean field connection
Alvaro Navarro-Rubio, Alejandro Lage-Castellanos
We propose a unified mean-field framework that bridges the dynamics of informal financial markets and formal markets governed by Limit Order Books (LOBs). Both settings are modeled…
Opinion formation by belief propagation: A heuristic to identify low-credible sources of information
Enrico Maria Fenoaltea, Alejandro Lage-Castellanos
With social media, the flow of uncertified information is constantly increasing, with the risk that more people will trust low-credible information sources. To design effective str…
City path tomography: reconstructing square road network from artificial users mobile phone data
Andy Rodriguez Lorenzo, Alejandro Lage-Castellanos
Population mobility can be studied readily and cheaply using cellphone data, since people's mobility can be approximately mapped into tower-mobile registries. We model people movin…
Ancestral Sequence Reconstruction for Co-evolutionary models
Edwin Rodríguez Horta, Alejandro Lage-Castellanos, Roberto Mulet
The ancestral sequence reconstruction problem is the inference, back in time, of the properties of common sequence ancestors from measured properties of contemporary populations. S…
