Long-range spatial correlations and fluctuation statistics of lightning activity rates in Brazil
H. V. Ribeiro, F. J. Antonio, L. G. A. Alves +2
We report on a statistical analysis of the lightning activity rates in all Brazilian cities. We find out that the average of lightning activity rates exhibit a dependence on the la…
Quantizations from (P)OVM's
Hervé Bergeron, Evaldo M. F. Curado, Jean-Pierre Gazeau +1
We explain the powerful role that operator-valued measures can play in quantizing any set equipped with a measure, for instance a group (resp. group coset) with its invariant (resp…
Localized coherence in two interacting populations of social agents
J. C. González-Avella, M. G. Cosenza, M. San Miguel
We investigate the emergence of localized coherent behavior in a system consisting of two populations of social agents possessing a condition for non-interacting states, mutually c…
Evolving cellular automata for diversity generation and pattern recognition: deterministic versus random strategy
Marcio Argollo de Menezes, Edgardo Brigatti, Veit Schwämmle
Microbiological systems evolve to fulfill their tasks with maximal efficiency. The immune system is a remarkable example, where self-non self distinction is accomplished by means o…
Symmetric generalized binomial distributions
H. Bergeron, E. M. F. Curado, J. P. Gazeau +1
In two recent articles we have examined a generalization of the binomial distribution associated with a sequence of positive numbers, involving asymmetric expressions of probabilit…
Controlling self-organized criticality in complex networks
Daniel O. Cajueiro, Roberto F. S. Andrade
A control scheme to reduce the size of avalanches of the Bak-Tang-Wiesenfeld model on complex networks is proposed. Three network types are considered: those proposed by Erdős-Reny…
Antipersistent behavior of defects in a lyotropic liquid crystal during annihilation
H. V. Ribeiro, R. R. Guimaraes, R. T. Teixeira-Souza +4
We report on the dynamical behavior of defects of strength s = +/- 1/2 in a lyotropic liquid crystal during the annihilation process. By following their positions using time resolv…
Unconventional Fano effect and off-resonance field enhancement in plasmonic coated spheres
Tiago J. Arruda, Alexandre S. Martinez, Felipe A. Pinheiro
We investigate light scattering by coated spheres composed of a dispersive plasmonic core and a dielectric shell. By writing the absorption cross-section in terms of the internal e…
Bridging stylized facts in finance and data non-stationarities
Sabrina Camargo, Silvio M. Duarte Queiros, Celia Anteneodo
Employing a recent technique which allows the representation of nonstationary data by means of a juxtaposition of locally stationary patches of different length, we introduce a com…
