Librarians at the National Library of Medicine tag each biomedical abstract to be indexed by their Pubmed information system with terms from the Medical Subject Headings (MeSH) terminology. The MeSH terminology has over 26,000 terms and indexers look at each article's full text to assign a set of most suitable terms for indexing it. Several recent automated attempts focused on using the article...

Morgagni Hernia is a rare form of diaphragmatic hernia. It is mainly asymptomatic and often identified incidentally during surgery. Tension-free synthetic mesh repair is the preferred treatment modality. However, the use of synthetic mesh concurrently during a clean-contaminated surgery such as sleeve gastrectomy remains controversial due to the remote possibility of mesh infection. A middle-ag...

To compare two tension free techniques, darning versus mesh repair in cases of inguinal hernia. Prospective study was done in Tikrit Teaching Hospital. Ninety-six patients with nonobstructive unilateral reducible and primary inguinal hernia 48 patients operate with mesh and other 48 patients operate with darn repair. The two techniques where compared with respect to effectiveness, post-operativ...

A Hierarchical 3D-Mesh (H3DM) Network is a 2D-mesh network of multiple basic modules (BMs), in which the basic modules are 3D-torus networks that are hierarchically interconnected for higher-level networks. In this paper, we evaluate the dynamic communication performance of a Hierarchical 3D-Mesh (H3DM) network using a deadlock-free routing algorithm with minimum number of virtual channels unde...

In this paper, a fast and efficient busy-list sub-mesh allocation strategy, referred to as Turning Busy List (TBL), is suggested for 3D mesh connected multicomputers. Turning means that the orientation of the allocation request is changed when no sub-mesh is available in the requested orientation. The TBL strategy considers only those available free sub-meshes that border from the left on some ...

In this paper, a fast path planning method by optimization of a path graph for both efficiency and accuracy is proposed. A conventional quadtree-based path planning approach is simple, robust, and efficient. However, it has two limitations. The first limitation is that many small cells are required to represent obstacles because the positions and shapes of the cells are not object-dependent and...

The accuracy and eeciency of the solution to numerical systems depends on the quality of the mesh used. Automatic mesh generation and adaptive reenement methods can, however, produce poor quality elements, even invalid elements, for quadrilateral or hexahedral mesh. We present an optimization-based approach for quadrilateral or hexahedral mesh untangling that maximizes the minimum area or volum...

We present a coupled moving mesh and level set method for computing incompressible two-phase flow with surface tension. This work extends a recent work of Di et al. [SIAM J. Sci. Comput., 26 (2005), pp. 1036-1056] where a moving mesh strategy was proposed to solve the incompressible Navier-Stokes equations. With the involvement of the level set function and the curvature of the interface, some ...

A method for performing anisotropic unstructured mesh adaptation is discussed that is well suited for computational fluid dynamics on parallel distributed memory computers. This algorithm which involves mesh motion, rather than refinement and coarsening, is fast, parallel, and fully conservative. The approach is effective at accurately capturing free-surface flows, boundary layers, and unsteady...

OBJECTIVE To assess perioperative and short-term outcomes after tension-free vaginal mesh repair of pelvic organ prolapse in local Chinese women. DESIGN Case series. SETTING The urogynaecology unit of a university teaching hospital in Hong Kong. PATIENTS All women with stage III or more pelvic organ prolapse who underwent tension-free vaginal mesh repair with or without vaginal hysterecto...
