The consequences of hesitation: Axelrod model with intrinsic noise
Rémi Perrier, Yérali Gandica, Laura Hernández
We study the influence of hesitating agents in the Axelrod model by introducing an intrinsic noise, which is proportional to the disagreement between the interacting agents, and th…
Evolution of the political opinion landscape during electoral periods
Tomás Mussi Reyero, Mariano G. Beiró, J. Ignacio Alvarez-Hamelin +2
We present a study of the evolution of the political landscape during the 2015 and 2019 presidential elections in Argentina, based on the data obtained from the micro-blogging plat…
Breaking the spell of nestedness
Clàudia Payrató Borrás, Laura Hernández, Yamir Moreno
Mutualistic interactions, which are beneficial for both interacting species, are recurrently present in ecosystems. Observations of natural systems showed that, if we draw mutualis…
Regions of attraction, limits and end points of an exterior discrete semi-flow
J. M. García-Calcines, L. J. Hernández, M. Marañón +1
An exterior space is a topological space provided with a quasi-filter of open subsets (closed by finite intersections). In this work, we analyze some relations between the notion o…
Does Phylogenetic Proximity Explain Nestedness in Mutualistic Ecosystems?
R. P. J. Perazzo, Laura Hernández, Horacio Ceva +2
We investigate how the pattern of contacts between species in mutualistic ecosystems is affected by the phylogenetic proximity between the species of each guild. We develop a dynam…
Phylogenetic Proximity and Nestedness in Mutualistic Ecosystems
R. P. J. Perazzo, Laura Hernández, Horacio Ceva +2
We investigate how the pattern of contacts between species in mutualistic ecosystems is affected by the phylogenetic proximity between the species of each guild. We develop several…
Study of the influence of surface anisotropy and lattice structure on the behaviour of a small magnetic cluster
Laura Hernández, Claire Pinettes
We have studied by Monte Carlo simulations the thermal behaviour of a small (N=13 particles) cluster described by a Heisenberg model, including nearest-neighbour ferromagnetic inte…
