A new computational method for creating all-hex meshes of thin-walled solids is presented. The proposed method creates an all-hex mesh in a three-step process. First, a tet mesh of the target geometric domain is created, and a layer of prism elements is inserted on the boundary of the mesh. Second, a sequence of novel topological transformations and smoothing operations is applied to reduce the...

Combined genetic and epigenetic analysis of sporadic colon cancer suggest that it can no longer be viewed as a single disease. There are at least three different subsets with distinct clinico-pathologic features, with important implications for preventions, screening, and therapy.

A increasing chorus of voices in the last few years has been telling us that the book is dead, and that hypertext and hypermedia will bring about fundamental changes in reading and writing. Also in prospect are radical changes in learning: the introduction of the computer will force teachers to rethink their practices, while students will be empowered to learn in new ways. Although this perspec...

The transition from the industrial age and the growing impact of the global economy on human life which has led to rapid expansion of western urban design culture in countries like Iran, are among the reasons why nowadays there is only a memory left in our minds of our traditional cities. "Urban identity" is one of the most important and most controversial issues among urban designers and other...

Generic programming plays an essential role in C++ software through the use of templates. However, both the creation and use of template libraries is hindered by the fact that the language does not allow programmers to specify constraints on generic types. To date, no proposal to update the language to provide concepts has survived the committee process. Until that time comes, as a form of earl...

Blood islands are conglomerations of prevascular stem cells that form during vasculogenesis, a function critical to early vascular and hematopoietic development. In this paper, a model of blood island formation is proposed employing the approach of classical enzyme kinetics. Deterministic simulations of the model show the formation of blood island-like structures. These are compared to murine b...

background: scorpions are known as the most widespread poisonous creatures that cause casualties and death to human. they are distributed in tropical and subtropical areas. among the sixteen iranian island in the persian gulf, qeshm island is the biggest and is located in the focus of the important internal and international commercial marinelines. furthermore, thousands of tourists also visit ...

This study was conducted to determine Pb (Pb) and Cd (Cd) concentrations in the liver and muscle of Platycephalus indicus (flathead) in Minab, Qeshm Island and Khamir Port in the Northeastern Persian Gulf. Moreover, the influences of season (winter and summer) and target tissue (liver and muscle) on the Pb and Cd concentrations in flathead were investigated and compared with FAO/WHO standards f...
