In clinical practice, the operator must decide which stent is most appropriate for the patient. This article focuses on the features of stent design Nike Jordan Heels
that make a specific stent more or less suitable for a particular type of lesion or anatomy: the “average” coronary lesion, the lesion situated on a curve, the Air Jordan 6 Retro
ostial lesion, Air Jordan Shoes Vancouver the bifurcational lesion, the lesion located at the left main stem, the calcified lesion, the chronic total occlusion, the small vessel, the saphenous vein graft, acute or threatened vessel closure, and special situations such as coronary aneurysms and perforations.
The leader-following consensus problem of higher order multi-agent systems is considered. In the system, the dynamics of each agent and the leader is a linear system. The control of each agent using local information is designed and detailed analysis of the leader-following consensus is presented for both fixed and switching interaction topologies, which describe the information exchange between the multi-agent systems. The design technique is based on algebraic graph theory, Riccati inequality and Lyapunov inequality. Simulations indicate the capabilities of the algorithms.
