The lengths of admixture tracts.
The distribution of admixture tract lengths has received considerable attention, in part because it can be used to infer the timing of past gene flow events between populations. It is commonly assumed that these lengths can be modeled as independently and identically distributed (iid) exponential random variables. This assumption is fundamental for many popular methods that analyze admixture us...
متن کاملA note on the distribution of admixture segment lengths and ancestry proportions under pulse and two-wave admixture models
Admixed populations are formed by the merging of two or more ancestral populations, and the ancestry of each locus in an admixed genome derives from either source. Consider a simple “pulse” admixture model, where populations A and B merged t generations ago without subsequent gene flow. We derive the distribution of the proportion of an admixed chromosome that has A (or B) ancestry, as a functi...
متن کاملInference of historical changes in migration rate from the lengths of migrant tracts.
After migrant chromosomes enter a population, they are progressively sliced into smaller pieces by recombination. Therefore, the length distribution of "migrant tracts" (chromosome segments with recent migrant ancestry) contains information about historical patterns of migration. Here we introduce a theoretical framework describing the migrant tract length distribution and propose a likelihood ...
متن کاملFungal Diseases of the Respiratory Tracts-Section 4
Fusarium spp., have been recognized during the past decade to cause disseminated infection, particularly in granulocytopenic patients undergoing intensive antileukemic chemotherapy or bone marrow transplantation. The lung, sinuses, and skin are the primary portals of entry. The periungual regions of the toes notably may be a particularly important site of initial invasion. Invasive Fusarium inf...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
