Therefore, at P lot i must be saturated and further evolution of the bilateral competition frontier ( {widehat{x}}_{i{j}_1}left tilde{t}right) ) is strictly monotonously increasing (bilateral competition of type shown in Fig. 4b).
This stronger preference for the lot closer to the entry point L is also seen in the further evolution of the bilateral frontier.
A parametric analysis with respect to ( tilde{t} ) yields the evolution of the bilateral frontier in the demand space ( left tilde{x},tilde{t}right) ) (as described in section 5.1.2).
Or, it is unsaturated at P (case 2), in which case the intersecting segment has slope − wγ/(2β − γ) and the further evolution of the bilateral frontier ( {widehat{x}}_{i{k}_1}left tilde{t}right) ) is also monotonously decreasing.
Clearly, further studies are warranted specially localization studies in an age stratified manner to more clearly highlight the evolution of a mostly bilateral phenomenon into a mostly unilateral phenomenon with advancing age from childhood to adult life.
Because they do not have internal body cavities, Platyhelminthes were regarded as a primitive stage in the evolution of bilaterians (animals with bilateral symmetry and hence with distinct front and rear ends).
Therefore, 'unilateral moyamoya' is possibly at one end of the spectrum of non-progressive intracranial arteriopathies, and may therefore be diagnosed as TCA or PVA, provided that long-term angiographical follow-up does not reveal bilateral evolution of disease (Fig. 5).
Reviewer 1: Gáspár Jékely This is an interesting analysis providing a physical explanation for the maintenance of bilateral symmetry in animal evolution.
Here we show, with very simple physical laws, that locomotion in three-dimensional macro-world space is itself sufficient to explain the maintenance of bilateral symmetry in animal evolution.
