With China’s economy transitioning from high-speed to high-quality development, whether and how to achieve functional upgrading in Global value chains (GVCs) are crucial, which are yet to be demonstrated. This study provides a long-term macro-economic analysis of the functional upgrading in...

A modeling method is proposed for steady-state thermal analysis of the “core-build” multilayer PCB structure based on coupling the analytical solution and numerical analysis. The analytical solution of the core in the PCB is expressed according to the Fourier-series solution of temperature...
