The generalized stability of the secondary atmospheric circulation over strong SST fronts is studied using a hydrostatic, Boussinesq two dimensional f-plane model. It is shown that even in a parameter regime in which these circulations are stable to small perturbations, significant non-normal growth of optimal initial perturbations occurs. The maximum growth factor in perturbation total energy ...

preeclampsia is an important pregnancy disorder with serious maternal and fetal complications which its etiology has not been completely understood yet. early diagnosis and management of disease could reduce its potential side effects. the vascular endothelial growth factor (vegf) family including vegf-a is the most potent endothelial growth factor which induces angiogenesis and endothelial cel...

Background: Human embryonic stem cells (hESC), which are derived from the inner cell mass of the blastocysts, have been considered to be pluripotent cells. In this study we examine the differentiating potential of hESC into hepatocytes by characterization of the expression of endoderm and liver-specific genes. Methods: hESC were cultivated in suspension to form aggregates, the embryoid bodies. ...
