This paper is devoted to the existence and stability analysis of limit cycles in a delayed mathematical model for the economy growth. Specifically the Solow model is further improved by inserting the time delay into the logistic population growth rate. Moreover, by choosing the time delay as a ...
The Gompertz model assumes that a population’s growth rate is density-dependent, that is, that the number of individuals in a later instant depends on the number of individuals previously, and the higher the initial number of individuals, the higher their growth rate will be. It is also par...
Therefore, for the spread quantity of Asian giant hornets, we establish a logistic population growth model to predict it. According to relevant literature [45], hornets in a honeycomb will die around December in winter, leaving only the queen to hibernate. In spring, the queen will come out...
One example could be the dataset used in [19], where the authors demonstrated that the min–max combination of three growth hormones (IGFBP3, IGF1, and GHBP) was superior to the other linear combinations for identifying autism. The aim of this evaluation would be to determine whether our ...
