An endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a rare skin tumor that most commonly occurs on the eyelids of elderly women. This tumor is morphologically analogous to endocrine ductal carcinoma in situ and solid papillary carcinoma of the breast. We describe one case of a 51-year-old male with an EMPSGC co-existing with mucinous carcinoma of the eyelid. The tumor was composed of...

Embedded in the substance of the pancreas are the peculiar bodies described by P. Langerhans and usually designated islands of Langer-hans. They are composed of polygonal cells arranged in irregular columns, between which are wide tortuous anastomosing capillaries. The cells are of epithelial type and have the same origin as those of the ducts and secreting acini with which, at an early period ...

In this article, the influence of hydrostatic stress and gravity on a clamped- free non homogeneous magneto electro elastic plate of polygonal cross sections is studied using linear theory of elasticity. The equations of motion based on two-dimensional theory of elasticity are applied under the plane strain assumption of prestressed and gravitated magneto electro elastic plate of polygonal cros...

In this paper, we propose a new shape feature for shapesimilarity search of 3D polygonal-mesh models in digital museum. The shape feature is an extension of the D2 shape functions proposed by Osada. Our proposed shape feature is a combination of geometry and texture which is also invariant to similarity transformation. Experiments showed that, our method achieved better performance improvement ...

In this paper we study the separability in the plane by two criteria: double-wedge separability and Θ-separability. We give an O(N logN)-time optimal algorithm for computing all the vertices of separating double wedges of two disjoint sets of objects (points, segments, polygons and circles) and an O((N/Θ0) logN)-time algorithm for computing a nearly-straight minimal Θ-polygonal chain separating...

Analytical solutions are presented for velocity and temperature distributions of laminar fully developed flow of Newtonian, constant property fluids in micro/minichannels for a wide variety of cross-sections. The considered geometries include hyper-elliptical channels and regular polygon ducts, which covers several common shapes. The analysis is carried out under the conditions of constant axia...
