بیماری مالتیپل اسکلروزیس (ms) از شایع ترین بیماری های نورولوژیک در انسان و شایع ترین بیماری منجر به ناتوانی در جوانان ذکر شده (1998 werring & thompson,) که با التهاب بافتی و آپوپتوز سلول های عصبی همراه می باشد. در ابتدا میلین تخریب شده و سلول های تولید کننده میلین یا الیگودندروسیت ها در مراحل بعدی آسیب می بینند (et al., 2006 cudrici). مکانیسم های پاتوژنیک بیماری به طور کامل شناخته نشده است اما ...

We show how a 3D model of a complex curved object can be easily extracted from a single 2D image. A userdefined silhouette is the key input; and we show that finding the smoothest 3D surface which projects exactly to this silhouette can be expressed as a quadratic optimization, a result which has not previously appeared in the large literature on the shape-from-silhouette problem. For simple mo...

Osteosarcoma is one of the most common malignant bone tumors in children and adolescents (Meyers et al., 1998; Bacci et al., 2000; Hauben et al., 2003; Chano et al., 2004; Marina et al., 2004; Benassi et al., 2007). The present therapeutic strategies in clinical applications have low efficiency under the current osteosarcoma therapy (Huang et al., 2012; Choeyprasert et al., 2013). Therefore, ne...

Microcystis aeruginosa is a major primary producer and a common toxic cyanobacterium, playing an important role in the aquatic environment (Chen et al., 2016). Microcystis aeruginosa is commonly observed in highly eutrophic lakes (Watanabe and Oishi, 1985). In recent years, surface cyanobacterial bloom occurred frequently in most large shallow lakes in China, such as Lake Taihu (Zhang et al., 2...

Evapotranspiration represents the combined loss of soil water from the earth’s surface to the atmosphere through evaporation of water from the soil or plant surfaces and transpiration via stomates of the plant. In agricultural production systems these two losses of water represent a major component of the water balance of the crop. If we examine evapotranspiration over time throughout a growing...

Early stochastic studies focused on steady-state, gravity-dominated unsaturated flow in unbounded domains In this study, on the basis of the van Genuchten–Mualem constitu(e.g., Yeh et al., 1985a,b; Russo, 1993, 1995a,b; Yang et tive relationship, we develop a general nonstationary stochastic model for transient, variably saturated flow in randomly heterogeneous meal., 1996; Zhang et al., 1998; ...
