Diffusion in Directed Modular Networks    [PDF]

C. H. Comin, M. P. Viana, L. Antiqueira, L. da F. Costa
Although many important systems can be represented by directed irregular
structures, there is a lack of studies concerning diffusion dynamics in such
systems. Here we take a first step towards this objective by showing that the
balance of connections among different network modules plays a crucial role in
defining the efficiency, i.e. the relationship between the activity of a given
node and its inward degree. Our findings are illustrated with respect to a real
cortical network and they indicate how the network topology can be used in
order to increase the efficiency of a given module. In addition, we show that
neither the modules topology nor the edges reciprocity inside the modules play
a crucial role in their efficiency.
