We are interested in describing the infected size of SIS Epidemic model using Birth-Death Markov process. The Susceptible-Infected-Susceptible (SIS) is defined within a population constant $M$; kept by replacing each death with newborn healthy individual. life span individual modelled an exponential distribution parameter $\alpha$; and disease spreads Poisson process rate $\lambda_{I}$. $\lambd...

conclusions: using these factors, nephrologists may predict the occurrence of graft loss or death. if the probability of graft loss was higher, physicians can decrease the immunosuppressive medications dosage to decrease the incidence of graft loss. patients and methods: fine-gray model was used for 266 cases with post-transplant malignancy in iran. these patients were followed-up from the diag...
