With the increase and diversification of network users, scale inter-domain routing system is becoming larger larger. Cascading failure analysis modeling are great significance to improve security networks. To solve problem that propagation principle cascading does not conform reality, a Failure Model for systems with Recovery Feedback Mechanism (CFM-RFM) proposed in this paper. CFM-RFM comprehe...

the acute diffuse hypoxia in dogs by general hypoxia, ligation of the coronary arteries and perfusion of the coronaries in the diffuse hypoxic hear ts. t he results of our experiments suggest that the quantitative diminu tion of oxygen and bloo d supply to the myocardium is, rather than oxygen differential , a determining fa ctor for development of ventr icular fi brillat ion or cardiac arrest.
