Here, we cannot get the condition of persistence for the predator population at present.
In this section, we will give a condition for the persistence of disease in epidemic model (2), and our main result is presented by the following theorem.
Of course, since organic animalists affirm and somatic animalists deny that being alive is a necessary condition of our persistence, Locke cannot be an ally to both camps.
Meng et al. [16] developed a stochastic chemostat model in a polluted environment and obtained the conditions of persistence and extinction for microorganism.
In addition, identifying and characterizing conditions of persistence opens a new line of study in evolutionary epidemiology, namely tracking viral evolutionary responses under different agro-ecological conditions.
In the following section, we derive the existence of a positive solution of system (5), an estimate of the solution, and give the conditions of persistence in the mean or extinction for both populations.
The expression of targets in the H-List, under conditions of persistence were analysed, from a set of microarray data.
Sufficient conditions of persistence in the mean or extinction for all the populations are obtained.
In order to consider the conditions of persistence in the mean and extinction for the prey and predator population, at first, we give two useful lemmas.
In some individuals haemoglobin switching is not complete and a significant amount of HbF is produced during adulthood, resulting in a condition called hereditary persistence of fetal haemoglobin (HPFH) [ 7].
The condition of lactase persistence (LP), found only in humans, allows the individual to continue to ingest and absorb lactose into adulthood.
