Sweep Line Algorithm for Convex Hull Revisited
Convex hull of some given points is the intersection of all convex sets containing them. It is used as primary structure in many other problems in computational geometry and other areas like image processing, model identification, geographical data systems, and triangular computation of a set of points and so on. Computing the convex hull of a set of point is one of the most fundamental and imp...
متن کاملThe consequences of genetic drift for bacterial genome complexity.
Genetic drift, which is particularly effective within small populations, can shape the size and complexity of genomes by affecting the fixation of deleterious mutations. In Bacteria, assessing the contribution of genetic drift to genome evolution is problematic because the usual methods, based on intraspecific polymorphisms, can be thwarted by difficulties in delineating species' boundaries. Th...
متن کاملAn Important Role for Purifying Selection in Archaeal Genome Evolution
As the null hypothesis of genome evolution, population genetic theory suggests that selection strength controls genome size. Through the process of genetic drift, this theory predicts that compact genomes are maintained by strong purifying selection while complex genomes are enabled by weak purifying selection. It offers a unifying framework that explains why prokaryotic genomes are much smalle...
متن کاملIranian EFL Learners’ Motivation Construction: Integrative Motivation Revisited
Although Gardner and his associates’ work was most influential in the field of L2 motivation, from the early 1990s onwards, their work has been criticized for several reasons. Some researchers claimed that integrative and instrumental orientations were no longer able to convey the complexity of the L2 motivation construct. To examine this complexity, the present study attempted to investigate t...
متن کاملCauses and Consequences of Genome Expansion in Fungi
Fungi display a large diversity in genome size and complexity, variation that is often considered to be adaptive. But because nonadaptive processes can also have important consequences on the features of genomes, we investigated the relationship of genetic drift and genome size in the phylum Ascomycota using multiple indicators of genetic drift. We detected a complex relationship between geneti...
