Via a sigmoid-like function, the discontinuous system is transformed into a continuous system. By numerical simulations, we reveal chaotic behaviors and also multistability, i.e., the existence of small pararheter windows where, for some fixed bifurcation parameter and depending on initial conditions, coexistence of stable attractors and chaotic attractors is possible. Moreover, we show that by using an algorithm to switch the bifurcation parameter, the stable attractors can be numerically approximated.展开更多

In this paper, we obtain Chen’s inequalities in (k,?μ)-contact space form with a semi-symmetric non-metric connection. Also we obtain the inequalites for Ricci and K-Ricci curvatures.

Al-though a leading vendorin China, ZTE has beencontinuously doing busi- ness in a prudent and practical way,which has been recognized by govern-ment authorities, carriers and customers.In order to learn more about ZTE’s NGNdevelopment strategy,we interviewedChen Jie, ZTE’s vice president and gen-eral manager of Network Division, aboutZTE’s NGN development strategy, R&Dadvantages and progress.展开更多

Here is a transcript of an interview given to our reporters by Wang Chen, director of the Office, on the Action Plan, which we hope will help our readers gain a better understanding of China＇s human rights cause and its development.展开更多
