A collaborative development mechanism model of regional economic system in metropolitan region is presented in this paper. The factors of accomplishing collaboration balance and development in metropolitan regions economic system are discussed.
This article illustrates a new research paradigm for financial crises forecasting. Using the Pressure-State-Impact-Response conception framework, a loop paradigm in which divides the problem of financial crisis early warning into pressure, state, impact and response is developed. Its characteristic of circular elements mobility can display the relation among the investors, markets and policy.
In this paper, on the basis of ODE methods and trust-region methods, we propose and analyze a new curvilinear trust-region method for unconstrained optimization. The new algorithm combines elements of ODE methods with elements of trust-region methods. Moreover, the new algorithm retains the quick covergence of trust-region method.
We propose a photonic crystal slab with an inflection point on the dispersion curve corresponding to a slow-light mode with reduced distortion, the transversely confined field and high quality factor of which are demonstrated.
