Systematic underestimation of the age of selected alleles
A common interpretation of genome-wide selection scans is that the dispersal of anatomically modern humans out of Africa and into diverse environments led to a number of genetic adaptations. If so, patterns of polymorphism from non-African individuals should show the signature of adaptations dating to 40,000-100,000 Kya, coinciding with the main exodus from Africa. However, scans of polymorphis...

However, this picture may not be evident immediately after injury, despite its severity, particularly in young he...

متن کاملSystematic underestimation of the thrust of vaults among some builders of the 19th century
In building manuals of the 18 and 19 century, we can often read either that vaults don't exert any outward thrust at all, or that their thrust can be easily absorbed by very simple means. Although the theories which are formulated to support these statements are not correct, they have been largely applied even after having been refuted. In case-studies of the works of three builders of vault co...
