Let N be the clutch size of the adult individual, m and f be the number of male offspring and the number of female offspring alive at breeding age respectively. We further assume that r is the proportion of male offspring, i.e., the sex ratio, in a clutch, 1 − r is ...
The right lung is bigger than the left and therefore receives a greater proportion of total ventilation in the upright and supine positions. The effect of gravity is also important. Lung tissue can be considered as semifluid or gel-like within the chest cavity. The weight of tissue above com...
The recent concept of DLB associated with AD should be taken into account. The sex ratio might be balanced between AD and PDD because of an association of DLB + AD in the group of DLB in our clinical cohort. In an autopsy study [18], females were more predominant in the DLB +...

Here we trained 4-day-old domestic chicks (Gallus gallus) to respond to stimuli depicting multiple examples of the proportion 4:1 when compared with the proportion 2:1. Stimuli were composed of green and red dot arrays; for the rewarded 4:1 proportion, 4 green dots for every red dot (e...
