A mathematical model for Babesiosis disease in bovine and tick populations

Aranda, Diego F.; Trejos, Deccy Y.; Valverde, Jose C.; Villanueva Micó, Rafael Jacinto (Wiley: 12 months, 2012-02)

In this paper, we analyze the Babesiosis transmission dynamics on bovine and tick populations. Ticks play a role of infec- tious agents and vector of the protozoan Babesia hemo-parasite. In this sense, we set out a ...
A mathematical model for human papillomavirus vaccination strategies in a random network

Villanueva Micó, Rafael Jacinto; Sánchez-Alonso, Víctor; Acedo Rodríguez, Luis (John Wiley & Sons, 2022-04)

[EN] In this paper, we consider a random network model for sexual contacts in a population developed from real statistical data in order to assess vaccination policies against sexually transmitted diseases (STDs). The model ...
A nonlinear dynamic age-structured model of e-commerce in Spain: Stability analysis of the equilibrium by delay and stochastic perturbations

Burgos-Simon, Clara; Cortés, J.-C.; Shaikhet, Leonid; Villanueva Micó, Rafael Jacinto (Elsevier, 2018)

[EN] First, we propose a deterministic age-structured epidemiological model to study the diffusion of e-commerce in Spain. Afterwards, we determine the parameters (death, birth and growth rates) of the underlying demographic ...
A particle swarm optimization algorithm with novelty search for combustion systems with ultra-low emissions and minimum fuel consumption
