Because the Isl2 null mutant pups died within 24 h after birth, the function of Isl2 during the eye-specific refinement is unknown.
Therefore, the birth rate function of mosquitoes is taken as (r_{m}N_{m} t-tau )e^{-d_{j} t-tau{-alpha N_{m}(t)}), where the meanings of the parameters can be found in Table 1.
The expression (px_{2}(t)/(q+x_{2}^{n}(t))) is a birth rates function of the susceptible pest population.
The function a gives the rate at which juveniles become adults and as adults give birth to juveniles, the function b corresponds to the birth rate of the population, e and f reflect the result of harvesting a portion of the population (fishing effort for marine population), c and d measure the competition between u and v.
The women describe that they wanted to experience a natural birth and the function of the female body [ 18, 20, 31], by working with the body [ 19], active participation [ 19], and giving their body an opportunity to experience natural childbirth [ 19].
We presented a new Bayesian approach, which provides a powerful tool to estimate rates of speciation and extinction on dated phylogenies based on the likelihood functions of the pure-birth, and birth-death processes while accounting for phylogenetic uncertainty and incomplete taxon sampling.
The theoretical volume of blood drawn off for biological tests during the first 30 days of life was noted and recorded as a function of the birth weight.
We intended in this study to explain the variation in birth outcomes as a function of the individual and area-based level SEM, measures of traffic and land use as indices of physical environment, and their interaction using a two-level hierarchical model.
The model follows the basic form of models produced by Anderson & May 19811) except that the host population is assumed to be dioecious and its birth rate is a function of the number of females.
The potential for an Allee effect [36], [37] is implicit in our choice of birth function (equation 9).
