in chapter one we will describe definitions and preliminary results to provide the global context of our own results to be presented in detail in the subsequent chapters in chapter two we consider degree-one maps of the circle and we study their rotation set. our main result in this chapter says that if the map is topologically mixing then its rotation interval is nontrivial (that is, not reduc...
PURPOSE Experimental animal models of myopia demonstrate that higher melatonin (Mel) and lower dopamine (DA) concentrations actively promote axial elongation. This study explored the association between myopia and serum concentrations of DA and Mel in humans. METHODS Morning serum concentrations of DA and Mel were measured by solid phase extraction-liquid chromatography-tandem mass spectromet...
The higher-order singular values for a tensor of order d are defined as the singular values of the d different matricizations associated with the multilinear rank. When d ≥ 3, the singular values are generally different for different matricizations but not completely independent. Characterizing the set of feasible singular values turns out to be difficult. In this work, we contribute to this qu...
In this study, growth performance, gonadosomatic index (GSI), and gonadal histology of beluga (Huso huso) and Persian sturgeon (Acipenser persicus) were investigated for 12 months. Sixty individuals of fifteen-month old beluga and Persian sturgeon with body mean weight of 781±55 g and 469.5±38 g, respectively, were distributed in the concrete tanks (5×1×1 m) with water capacity of 2.5 m3 in tri...
