In this paper, we propose a novel part-pair representation for part localization. In this representation, an object is treated as a collection of part pairs to model its shape and appearance. By changing the set of pairs to be used, we are able to impose either stronger or weaker geometric constraints on the part configuration. As for the appearance, we build pair detectors for each part pair, ...

Current deformable part models such as the ones introduced by Felzenszwalb et al. [2] let the parts deform only at a fixed predetermined scale relative to that of the root of the models (typically at twice the resolution). They do so because it enables them to find the optimal placement of each part efficiently, using a fast 2D distance transform algorithm. We demonstrate in our paper that if o...

The Ellipsoid algorithm was developed by (formerly) Soviet mathematicians (Shor (1970), Yudin and Nemirovskii (1975)). Khachian (1979) proved that it provides a polynomial time algorithm for linear programming. The average behavior of the Ellipsoid algorithm is too slow, making it not competitive with the simplex algorithm. However, the theoretical implications of the algorithm are very importa...

During the last two decades conventional therapy has improved the prognosis of thalassemia. However, despite such improvement it still remains a progressive disease with treatment-related complications such as hepatitis, liver fibrosis, and cardiac disease. Bone marrow transplantation (BMT) can prevent or delay progression of the aforementioned complications. The importance of clinical research...

Apelin is a recently discovered bioactive peptide, known to be an endogenous high-affinity ligandfor the previously orphan G protein-coupled receptor APJ. Apelin/APJ as a novel signaling pathwayhas been shown to play many crucial roles in cardiovascular function, blood pressure regulation, fluidhomeostasis, feeding behavior, obesity, type 2 diabetes mellitus, adipoinsular axis regulation, cellp...

introduction: multileaf collimator (mlc) is state of the art among the radiation field shaping systems for conformal radiotherapy techniques. some advantages of this system are as follow: reduction of treatment time, higher precision in conforming the radiation field to the projection of the target volume and lowering the chance of errors made by technologists. the purpose of this research was ...

hereby we report a case of well-differentiated intraosseous osteosarcoma in the sacrum. a 32-year-old woman was admitted to our hospital with a low echo-level mass in the pelvis searched by ultrasound in a routine physical examination. radiographically, the mass was misdiagnosed as a benign bony tumor originating from the sacrum. the tumor was completely resected and pathological diagnosis was ...
