seasonal activity and spatial distribution of eoteranychus frosti mcgregor, tydeus longisetosus (elbagouy and momen) and zetzellia mali ewing were studied during 9th july to 22th october 2006 in an unsprayed apple orchard, maragheh region, northwest of iran. also the density dependence interaction between preys and predator was assessed. to estimate the spatial distribution pattern of these spe...

In this study, we propose a function-on-function linear quantile regression model that allows for more than one functional predictor to establish flexible and robust approach. The proposed is first transformed into finitedimensional space via the principal component analysis paradigm in estimation phase. It then approximated using estimated functions, parameter of constructed based on scores. a...

This paper is showing the solution for two open problems about decidability of vector reachability problem in a finitely generated semigroup of matrices from SL(2,Z) and the point to point reachability (over rational numbers) for fractional linear transformations, where associated matrices are form SL(2,Z). The approach of solving reachability problems is based on analysis of reachability paths...
