Synchronization of coupled oscillators is often described using the Kuramoto model. Here we study a generalization of the Kuramoto model where oscillators communicate with each other through an external medium. This generalized model exhibits interesting new phenomena such as bistability between synchornization and incoherence and a qualitatively new form of synchronization where the external m...

in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...

since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...

increased arginase activity in the airways decreases l-arginine and causes deficiency of bronchodilating and anti-inflammatory nitric oxide (no) in asthma. as, it is suggested that l-arginine may have therapeutic potential in asthma treatment, we aimed to investigate the effects of inhaled l-arginine on oxygen saturation (sao₂) and airway histology in a murine model of acute asthma. twenty eigh...

We study the properties of hypernuclei containing one L hyperon in the framework of the correlated basis function theory with Jastrow correlations. Fermi hypernetted chain integral equations are derived and used to evaluate energies and one-body densities of L hypernuclei having a doubly closed shell nucleonic core in the j j coupling scheme, from carbon to lead. We also study hypernuclei havin...
