an analysis of the stages of crop growth presents an important step in the improvement of production management. through growth analysis, planning for planting systems, fertilization, pruning operations, harvest time as well as obtaining economical yield can be more accessible. therefore, a development of mathematical models simulating plant growth would be helpful in improving crop management,...

Ichthyosis hystrix of Curth-Macklin ( IHCM) is an extremely rare keratinization disorder, with verrucous to hystrixlike hyperkeratotic plaques of varying extent. The diagnosis is based on a distinctive pattern of epidermolytic hyperkeratosis and the presence of binucleate cells under light microscopy, as well as unique electron microscopic findings of continuous perinuclear tonofibril shells in...

We discuss microscopic mechanisms of complex network growth, with the special emphasis of how these mechanisms can be evaluated from the measurements on real networks. As an example we consider the network of citations to scientific papers. Contrary to common belief that its growth is determined by the linear preferential attachment, our microscopic measurements show that it is driven by the no...

Background Cystic fibrosis (CF) is the most prevalent lethal chronic genetic and multivariate disease, widespread in Iranian population. The aim of this study was to evaluate the condition of patients with CF from various dimensions in the last decades in Iran.<b...

Using kinetic Monte{Carlo simulations of a Solid{on{Solid model we investigate the innuence of step edge diiusion (SED) and evaporation on Molecular Beam Epitaxy (MBE). Based on these investigations we propose two strategies to optimize MBE{growth. The strategies are applicable in diierent growth regimes: during layer{by{layer growth one can reduce the desorption rate using a pulsed ux. In thre...

In this paper, we investigate the microscopic social mechanisms through agent based modeling and empirical data analysis with the aim to detect the intrinsic link between local structure balance and global pattern. Both investigations suggest that three types of social influences give rise to the emergence of macroscopic polarization, and the polarization pattern is closely linked with local st...

Introduction: Psoriasis occurs in 1-5% of population and admissions to hospitals include 6-8% of patients in the dermatological wards. Angiogenesis plays a role in pathogenesis of many skin disorders and it is one of basic phenomena observed in psoriasis. Aim: The aim of this study was to compare capillaroscopic images and neovascularisation factors in the patients diagnosed with psoriasis as w...
