We investigated whether the differences in perceptual awareness for stimuli at the threshold of awareness can arise from different global brain states before stimulus onset indexed by the EEG microstate. We used a metacontrast backward masking paradigm in which subjects had to discriminate between two weak stimuli and obtained measures of accuracy and(More)
Starting from Axelrod's model of cultural dissemination, we introduce a rewiring probability, enabling agents to cut the links with their unfriendly neighbors if their cultural similarity is below a tolerance parameter. For low values of tolerance, rewiring promotes the convergence to a frozen monocultural state. However, intermediate tolerance values(More)
It is assumed that global change is already affecting the composition, structure and distribution of forest ecosystems; however, detailed evidences of altitudinal and latitudinal shifts are still scarce. To develop a method based on National Forest Inventory (NFI) to assess spatio-temporal changes in species distributions. We develop an approach based on(More)
In this work we present a dynamical model that succesfully describes the organization of mutualistic ecological systems. The main characteristic of these systems is the nested structure of the bipartite adjacency matrix describing their interactions. We introduce a nestedness coefficient, as an alternative to the Atmar and Patter-son temperature, commonly(More)
Forty-one isolates obtained from apple fruit exhibiting the typical symptoms of bitter rot in Uruguay were characterized based on molecular, phenotypic and pathogenicity data. Four species were identified based on the analysis of ITS, GAPDH and BTUB2 genes. The dominant species was Colletotrichum fructicola (33/41 isolates) followed by C. theobromicola(More)
We study an opinion formation model by the means of a coevolving complex network where the vertices represent the individuals, characterized by their evolving opinions, and the edges represent the interactions among them. The network adapts to the spreading of opinions in two ways: not only connected agents interact and eventually change their thinking but(More)
