Early Back-to-Africa Migration into the Horn of Africa
Genetic studies have identified substantial non-African admixture in the Horn of Africa (HOA). In the most recent genomic studies, this non-African ancestry has been attributed to admixture with Middle Eastern populations during the last few thousand years. However, mitochondrial and Y chromosome data are suggestive of earlier episodes of admixture. To investigate this further, we generated new...
متن کاملTemporomandibular dysfunction syndrome associated with scuba diving mouthpieces.
As previous reports have highlighted that temporomandibular joint dysfunction syndrome can occur during scuba diving due to the use of a diving mouthpiece, 74 divers of varied experience (62 male, 12 female) were asked to evaluate the efficiency of the mouthpiece for the ease of grip, insertion into the mouth, clearing of water, air sharing, comfort and overall efficiency. They also recorded th...
متن کاملAirway efficiency during the use of SCUBA diving mouthpieces.
OBJECTIVE To investigate the effect of varying interdental bite platform thickness of the scuba mouthpiece on airway efficiency. METHODS 10 male divers had their mean peak flow measured for free breathing, maximum flow with diving mouthpiece, teeth in occlusion, and for five experimental mouthpieces with different thickness of interdental bite platform (1 mm, 2 mm, 3 mm, 4 mm, and 5 mm). RE...
متن کاملNumerical simulations of fluid-structure interactions in single-reed mouthpieces.
Most single-reed woodwind instrument models rely on a quasistationary approximation to describe the relationship between the volume flow and the pressure difference across the reed channel. Semiempirical models based on the quasistationary approximation are very useful in explaining the fundamental characteristics of this family of instruments such as self-sustained oscillations and threshold o...
متن کاملHorn Complements: Towards Horn-to-Horn Belief Revision
Horn-to-Horn belief revision asks for the revision of a Horn knowledge base such that the revised knowledge base is also Horn. Horn knowledge bases are important whenever one is concerned with efficiency—of computing inferences, of knowledge acquisition, etc. Horn-to-Horn belief revision could be of interest, in particular, as a component of any efficient system requiring large commonsense know...
