The Poisson ratio (PR) is a fundamental mechanical parameter that approximates the ratio of relative change in cross sectional area to tensile elongation. However, the PR of extraocular muscle (EOM) is almost never measured because of experimental constraints. The problem was overcome by determining changes in EOM dimensions using computed X-ray tomography (CT) at microscopic resolution during ...
Classical limits of quantum groups give rise to multiplicative Poisson structures such as Poisson-Lie and quasi-Poisson structures. We relate them the notion a shifted structure which gives conceptual framework for understanding classical (dynamical) r -matrices, groupoids so on. also propose symplectic realization show that Manin pairs triples examples such.
Background : Large intestine cancer is ranked second among gastrointestinal cancers and is the fourth common cancer in Iran. The aim of this study is to map the county-level of large intestine cancer incidence rate in Iran using Area-to-Area Poisson Kriging method and also to identify the high-risk areas. Methods : This study was application/ecology. The methodology was illustrated using la...
Background and purpose: Cancer is the third leading cause of death in Iran. Mazandaran and Golestan provinces, especially in northern countries, have a high incidence of gastrointestinal cancer. Therefore, we aimed to find the geographic distribution of standardized mortality rates of this disease and to mark differences between the cities on a map. Materials and methods: The data related to t...
