Our choice of birth function also implicitly assumes random mating among healthy and parasitized individuals.
The potential for an Allee effect [36], [37] is implicit in our choice of birth function (equation 9).
The expression (px_{2}(t)/(q+x_{2}^{n}(t))) is a birth rates function of the susceptible pest population.
With birth, the function of gas exchange is transferred from the placenta to the lungs, and therefore from the systemic circulation to the pulmonary circulation.
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.
They underline the truth, which is that there are risks to any birth, wherever it takes place, but that the risks of needing unnecessary intervention are increased in a highly-medical setting, and that the majority of women do best at home or in a home-from-home environment, where stress levels stay down and the natural process of birth functions best.
The left panel of Figure 2 plots rich-poor disparities in facility births as a function of percentage of births in a private facility.
To model the place effects from housing markets, I plot age at first birth as a function of sales and rents and then add potential controls/explanations for the variations in age at first birth.
For instance, a person's allotment of neuropeptide Y (NPY), a neurotransmitter in the brain that regulates stress responses, among other things, is relatively fixed from birth, more a function of heredity than of learning.
