we described a case of lymphoid follicular hyperplasia that arose from the ileum of a 52-year-old woman. her colonoscopy revealed a large mass in the cecum associated with multiple polypoid lesions in the ileum. histologic examination demonstrated severe lymphocytic infiltration and lymphoid follicles with regular germinal centers, without evidence of malignancy. a right hemicolectomy was perfo...

The frame-to-global-model approach is widely used for accurate 3D modeling from sequences of RGB-D images. Because still no perfect camera tracking system exists, the accumulation of small errors generated when registering and integrating successive RGB-D images causes deformations of the 3D model being built up. In particular, the deformations become significant when the scale of the scene to ...

The flame forming process is widely used to manufacture ship hull plates. The saddle-shaped surfaces have different curvatures in perpendicular angles of planes and the manufacturers face an anti-clastic curvature. In this article, the manufacturing of saddle-shaped surfaces utilizing the flame forming process is investigated. The spiral irradiating scheme is used for forming. In order to study...
