| contents | Coherence Resonance in an Epidemic Model with Noise Yi Wang Jianzhong Wang Física, Astronomía y Matemáticas Noise Coherence resonance Basic reproduction number Epidemic models frequently contain thresholds that determine the survivability of competing strains. In the model we study in this paper, if the basic reproduction number is less than one, the disease will disappear, otherwise the disease will persist. Interestingly, we find that additive noise of an appropriate intensity and temporal correlation can reverse this in a resonance-like manner. By using analogies from the theory of noise-driven dynamical system, we thus observe an evolutionary coherence resonance, similar to what has been reported previously in evolutionary games. Potential implications of our results for real-life field observations are also discussed. 2012 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46423465010 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3-4 Vol.42 |
