Retinal image registration is important to assist diagnosis and monitor retinal diseases, such as diabetic retinopathy and glaucoma. However, registering retinal images for various registration applications requires the detection and distribution of feature points on the low-quality region that consists of vessels of varying contrast and sizes. A recent feature detector known as Saddle detects ...

leprosy is an infectious and non-fatal disease that mainly involved skin and peripheral nervous system and caused by mycobacterium lepra. this case is a 41-year-old woman with intermittent nasal bleeding and a mass (1.5×2.5 cm) in the right side of lateral nasal wall and a (1×1 cm) mass on septum in the left side of the nose. considering the probability of intranasal tumor, endoscopic biopsy fo...

introduction: nose morphology depends on gender, ethnicity, and environmental conditions. it can be used in identification of the race and sex of persons whose identity is unknown. nasal index is a useful tool in anthropometry. methods: in this study, nasal parameters of iranian males and females students were measured (nasal height, nasal width, and nasal index). this study was conducted on 20...

We demonstrate the relevance of saddle-splay elasticity in nematic liquid crystalline fluids in the context of complex surface anchoring conditions and the complex geometrical confinement. Specifically, nematic cells with patterns of surface anchoring and colloidal knots are shown as examples where saddle-splay free energy contribution can have a notable role which originates from nonhomogeneou...

Bicycle saddle height configuration may affect pedal force application. Our aim was to compare pedal force effectiveness for different saddle height configurations. Eleven cyclists (38 ±12 years) and eleven triathletes (44 ±8 years) with competitive experience performed 2-min trials at four different saddle heights (preferred, high, low, theoretical optimal) each separated by one minute of rest...

One of the most attractive recent approaches to processing well-structured large-scale convex optimization problems is based on smooth convex-concave saddle point reformulation of the problem of interest and solving the resulting problem by a fast First Order saddle point method utilizing smoothness of the saddle point cost function. In this paper, we demonstrate that when the saddle point cost...
