Mesenchymal stem cells offer several potential advantages over other types of stem cells for cardiac repair. Nevertheless, poor survival of donor cells is one of the major concerns that hampers a better prognosis. Integrins, which involved in cell/extracellular matrix (ECM) interaction and connexins (Cxs), with a dual role as an anti-apoptotic and(More)
Damage diagnosis and health monitoring of large-scale structures are becoming a hot research subject in the present structural engineering circle. Elman neural network is presented to identify and locate the crack damage of a radial gate located in the middle reaches of the main stream of the Jialing River. This method is an aggregation neural networks and(More)
RBF neural network is presented to identify and locate the crack damage of concrete structures in this paper. A cantilever is analyzed by finite element method, and the damage indices of the perfect structure and damaged structure are gained. Then RBF neural network is used to analyze the single damage and multi-damage quantification and damage location.(More)
Damage diagnosis and health monitoring of large-scale structures are becoming a hot research subject in the present structural engineering circle. Aimed at many operating safe problems of hydraulic structure, a method applied to radial gate is put forward. This method is an aggregation of vibration theory, neural networks and pattern identification, and(More)
