These contemporary patterns of divergence and distribution observed for these genera of dolphin inspired the west-wind drift hypothesis, which suggests an eastward dispersal of dolphins via a unidirectional, linear route with the temperate west-wind drift ocean current present during the Plio-Pleistocene.
The bi-objective Unidirectional Road Network with Disruptions and strong connecting requirements (bi-URND) aims at simultaneously minimizing the number of link reversals and the total costs to route one unit of flow between every pair of origins and destinations, such that the final network remains strongly connected.
Here, rather than estimate M, we used the output ln marginal likelihoods (ln(ml)) to choose among different migration models (Beerli and Palczewski 2010) and reconstruct the minimal, most probable, set of unidirectional migration routes among the new and highly-resolved population dataset.
We tested the hypothesis of a unidirectional, linear dispersal route by examining the geographic partitioning of genetic variation.
Published: November 26, 2014 Until recently, it was assumed that differentiation was mostly a unidirectional and irreversible route that cells undertake during lineage commitment.
Once the directionality of the transient state has been established, both heads follow the same constrained route resulting in an efficient, unidirectional motion.
The most famous of these is the 'Traveling Salesman' problem, which involves determining whether there is some possible route through the nodes of a graph connected by unidirectional arrows that visits each node exactly once.
The route continues on Ellicott for nine blocks to the unidirectional East Tupper Street, where NY 5 westbound separates from the route once more.
And in the few instances where big oil companies have entered the renewable energy market, they have followed the traditional route of centralizing production and feeding the electricity into a unidirectional power grid.
The uptake route is composed of organelles, known as endosomes that communicate in a unidirectional manner from early to late endosomes to lysosomes.
