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...
Numerous chemical data sets have become available for quantitative structure-activity relationship (QSAR) modeling studies. However, the quality of different data sources may be different based on the nature of experimental protocols. Therefore, potential experimental errors in the modeling sets may lead to the development of poor QSAR models and further affect the predictions of new compounds....
It is now widely accepted that many countries in East Asia achieved a remarkable record of high and sustained economic growth. This achievement is possibly one of the most important economic developments in the past generation. Explaining East Asia’s success is extremely important, for at least two reasons. First, such an explanation might show the way to replicate this success in other regions...
1. Epidemiological and clinical studies from the past 50 years provide unequivocal evidence for a close association and causative links between psychological stresses and cardiovascular dysfunction in humans. Not surprisingly, numerous animal experiments have been undertaken in an attempt to clarify underlying pathophysiological mechanisms. The present review focuses on animal models that provi...
