We show that Y. Cheung’s general Z-continued fractions can be adapted to give approximation by saddle connection vectors for any compact translation surface. That is, we show the finiteness of his Minkowski constant for any compact translation surface. Furthermore, we show that for a Veech surface in standard form, each component of any saddle connection vector dominates its conjugates. The sad...

conclusions saddle nose reconstruction with bone graft in multiple facial fracture patients is a predictable method if surgical accesses to the region are carefully designed, considering the accompanying fractures. results there were 11 patients treated using this method. the male-to-female ratio was 7:5. one miniscrew with the lag technique was the preferred method for the fixation of the dors...

Line drawings produced by contours traced on a surface can produce a vivid impression of the surface shape. The stability of this perception is notable considering that the information provided by the surface contours is quite ambiguous. We have studied the stability of line drawing perception from psychophysical and computational standpoints. For a given family of simple line drawings, human o...

INTRODUCTION Saddle nose deformity due to autoimmune diseases such as Wegener's Granulomatosis and Relapsing Polychondritis is aesthetically, functionally and psychologically distressing for patients. However, "reliable" options for surgical correction remain limited in the literature. We present our experience of augmentation rhinoplasty in this patient population focussing on the techniques a...

A unique octanuclear copper(II) cluster with a saddle-shaped structural topology has been prepared from a large, flexible polydentate ligand comprising a 4,4'-bipyridine linker bearing four pendant pyrazolate heterocycles.
