Rough Infection Fronts in Random Media
A. B. Kolton, K. Laneri We study extended infection fronts advancing over a spatially uniform susceptible population by solving numerically a diffusive Kermack McKendrick SIR model with a dichotomous spatially random transmission rate, in two dimensions. We find a non-trivial dynamic critical behavior in the mean velocity, in the shape, and in the rough geometry of the displacement field of the infective front as the disorder approaches a threshold value for spatial spreading of the infection. arxiv , EPJB , highlight Heterogenous Transmission Spatial SIR model applet [mousse drag->infect, keypress->pause]
Riesgómetro COVID19
¿Cómo cuantificar el riesgo sanitario de la COVID-19 con la serie de casos diarios? ¿Es posible predecir el número de casos en los próximos días? ¿Cuál es el verdadero número de infectados activos? Con el diagrama de riesgo intentamos responder estas y otras preguntas para muchas ciudades del país, visitalo en: Riesgometro COVID19
Thermally rounded depinning of an elastic interface on a washboard potential
A. B. Kolton, E. A. Jagla The thermal rounding of the depinning transition of an elastic interface sliding on a washboard potential is studied through analytic arguments and very accurate numerical simulations. arxiv Interface in a tilted washboard potential.
