In particular, the existence and the uniqueness of Nash Equilibrium(NE) strategies for noncooperative mode are proved. In addition, a distributed iterative algorithm is proposed to obtain the optimal solutions of the scheme. Simulation studies are carried out to show the performance comparison between two modes as well as the system revenue improvement of the proposed scheme compared with a conventional scheme without a virtual price control factor.展开更多

The difficulty of this task lies in the limitations in legal thinking resulting from the division of labor in the legal profession. A clear perception of the nature of intellectual property rights and the intellectual property rights system can only be obtained when we transcend intellectual property rights law. If we adopt the thinking of legal philosophy and the logic of dialectics to analyze the intellectual property rights system and explore the differing nature of institutional structures and their interrelationships, we can show that the intellectual property rights system is essentially an institutional arrangement involving balancing different considerations and implying a high level of political intellect. Only when intellectual property rights legislation possesses this kind of wisdom will people voluntarily abide by its rules in their life and work.展开更多
