The specialized masticatory apparatus of Permo-Triassic dicynodonts (herbivorous mammal-like reptiles) is described and its function analysed by comparison of an archaic dicynodont, the pristerodont Emydops, with the advanced dicynodont Lystrosaurus. A unique feature of the dicynodont masticatory apparatus was the fact that the jaw joint consisted of two convex articulating surfaces which permi...

An oblique line translating vertically behind a horizontal rectangular aperture is perceived as moving in the horizontal direction, i.e., in the line-ending’s direction. When a feature is added on the line, and thus provides a vertical unambiguous motion signal, the line’s perceived direction is still horizontal. In parallel, the feature appears to slide obliquely along the line (Wallach, 1935)...

PURPOSE To measure horizontal and vertical lamina cribrosa (LC) tilt angles and investigate associated factors using prototype optical coherence tomography (OCT) with a broad wavelength laser light source. DESIGN Cross sectional study. METHODS Twenty-eight no glaucoma eyes (from 15 subjects) and 25 glaucoma eyes (from 14 patients) were enrolled. A total of 300 optic nerve head B-scans were ...

Line-ends, corners and junctions are important singularities for form analysis, object recognition, depth ordering or motion processing. In this study, we investigate the extent to which processing the motion of line ends depends on the spatial configuration of their immediate surround. To that aim, we used two vertical collinear line segments, translating clockwise or anti-clockwise along a ci...

In this study, idealized simulations of squall line traversing a bell-shape mountain in a three-dimensional framework are conducted using the Weather Research and Forecasting (WRF) model, version 3.2.0, with 2-km horizontal grid size and 60 vertically stretched layers. Water vapor and condensate budgets are examined, and the temporal variations of four microphysics ratios, including precipitati...

In this paper, we consider a map labeling problem to maximize the number of independent labels in the plane. We first investigate the point labeling model that each label can be placed on a given set of anchors on a horizontal line. It is known that most of the map labeling decision models on a single line (horizontal or slope line) can be easily solved. However, the label number maximization m...
