Irregularity in dengue fever epidemics: difference between first and secondary infections drives the rich dynamics more than the detailed number of strains
Maíra Aguiar, Bob W. Kooi, Nico Stollenwerk
Different extensions of the classical single-strain SIR model for the host population, motivated by modeling dengue fever epidemiology, have reported a rich dynamic structure inclu…
Universal Fluctuations of AEX index
Rui Gonçalves, Helena Ferreira, Alberto Pinto
We compute the analytic expression of the probability distributions F{AEX,+} and F{AEX,-} of the normalized positive and negative AEX (Netherlands) index daily returns r(t). Furthe…
Torus bifurcations, isolas and chaotic attractors in a simple dengue model with ADE and temporary cross immunity
Maira Aguiar, Nico Stollenwerk, Bob W. Kooi
We analyse an epidemiological model of competing strains of pathogens and hence differences in transmission for first versus secondary infection due to interaction of the strains w…
The SIRI stochastic model with creation and annihilation operators
Nico Stollenwerk, Maira Aguiar
We generalize the well known formulation of the susceptibles, infected, susceptibles (SIS) spatial epidemics with creation and annihilation operators to the reinfection model inclu…
A new chaotic attractor in a basic multi-strain epidemiological model with temporary cross-immunity
Maíra Aguiar, Nico Stollenwerk
An epidemic multi-strain model with temporary cross-immunity shows chaos, even in a previously unexpected parameter region. Especially dengue fever models with strong enhanced infe…
River scaling analysis and the BHP universality hypothesis
Rui Gonçalves, Nico Stollenwerk, Alberto Pinto
The XY-model shows in two dimensions in the strong coupling regime a universal distribution, named BHP, which in turn also describes other models of criticality and self-organized…
