TL;DR: A general statistical model is developed that can detect concerted changes in aligned sequence data and apply it to study regular sound changes in the Turkic language family, demonstrating that a model with no prior knowledge of complex concerted or regular changes can nevertheless infer the historical timings and genealogical placements of events of concerted change from the signals left in contemporary data.

TL;DR: It is shown that migrating Bantu-speaking populations did not expand from their ancestral homeland in a “random walk” but, rather, followed emerging savannah corridors that emerged from the Congo rainforest, with rainforest habitats repeatedly imposing temporal barriers to movement.

TL;DR: In this article, the dispersion of a point-source release of a passive scalar in a regular array of cubical, urban-like obstacles is investigated by means of direct numerical simulations.

TL;DR: In this paper, the authors analyzed data from direct numerical simulations in arrays of building-like obstacles and found that the mean flow structure around the buildings exert a strong influence over the dispersion of material in the near field.

TL;DR: In this paper, simulations of flows at various directions over arrays of cubes representing typical urban canopy regions are presented and discussed, focusing on the differences in the mean flow within the canopy region arising from the different wind directions and the consequent effects on global properties such as the total surface drag.
