Causal asymmetry suggests productivity underlies scientific collaboration
Diego A. Frota, Cesar I. N. Sampaio Filho, Vitor H. Ribeiro +5
Scientific productivity and collaboration are closely related, yet the causal direction between these two dimensions of academic careers remains unclear. Here we analyze the career…
Evolving spatiotemporal patterns and urban scaling of deaths from external causes
Cesar I. N. Sampaio Filho, Humberto A. Carmona, Antonio S. Lima Neto +4
Urban scaling theory posits that urban indicators follow power-law relations with population, yet the evolution of these patterns - and the role of regional differences in settings…
Mapping Inter-City Trade Networks to Maximum Entropy Models using Electronic Invoice Data
Cesar I. N. Sampaio Filho, Rilder S. Pires, Humberto A. Carmona +1
We analyze the network of transactions among cities based on the electronic invoice database for the municipalities in the Ceará state, Brazil. It consists of approximately 3.7 bil…
Random networks with q-exponential degree distribution
Cesar I. N. Sampaio Filho, Marcio M. Bastos, Hans J. Herrmann +2
We use the configuration model to generate networks having a degree distribution that follows a -exponential, , for arbitrary values of the p…
Noise induced phase transition in the -state block voter model
J. M. de Araújo, C. I. N. Sampaio Filho, F. G. B. Moreira
We use Monte Carlo simulations and finite-size scaling theory to investigate the phase transition and critical behavior of the -state block voter model on square lattices. It is…
Itinerant conductance in fuse-antifuse networks
Cesar I. N. Sampaio Filho, Andre A. Moreira, Nuno A. N. Araujo +2
We report on a novel dynamic phase in electrical networks, in which current channels perpetually change in time. This occurs when the individual elements of the network are fuse-an…
Characterizing the intrinsic correlations of scale-free networks
J. B. de Brito, C. I. N. Sampaio Filho, A. A. Moreira +1
Very often, when studying topological or dynamical properties of random scale-free networks, it is tacitly assumed that degree-degree correlations are not present. However, simple…
Mandala Networks: ultra-robust, ultra-small-world and highly sparse graphs
C. I. N. Sampaio Filho, A. A. Moreira, R. F. S. Andrade +2
The increasing demands in security and reliability of infrastructures call for the optimal design of their embedded complex networks topologies. The following question then arises:…
