We introduce a novel framework for conceptualising, quantifying and unifying discordant patterns of species richness along geographical gradients. While not itself explicitly mechanistic, this approach offers a path towards understanding mechanisms. In this study, we focused on the diverse patterns of species richness on mountainsides. We conjectured that elevational range midpoints of species ...
Various dimensions of the human vestibular aqueduct were evaluated in two groups, patient and control, and these measurements were compared. Both groups were examined clinically, followed by audiometric evaluation and temporal bone high resolution CT scan. It was found that in approximately one third of the patient group (with idiopathic SNHL), the vestibular aqueduct was 1.5 mm or larger. ...
BACKGROUND AND PURPOSE The size of vestibular aqueducts (VAs) seen on CT studies varies. The current practice of calling a VA enlarged when it exceeds a certain threshold (eg, 1.5 mm at the midpoint) is arbitrary. Our hypothesis was that statistical analysis of the range of VA widths in a normal-hearing population would lead to a mathematic definition of the upper-limit-of-normal VA width. MA...
