Biofluid mechanics investigation on obstructed pulmonary lower airway reopening: theoretical analysis;

An investigation of multiple cracking in brittle reaction zone at interfaces of unidirectional composites with longitudinal tensile has been made by using three concentric circular cylinder model,and shcar-lay ana-Iysis proposed by Cox.

By combining the niche technology into the selection mechanism of EP and restart strategy into the framework of EP, we use niche technology to prevent the premature convergence phenomenon, while restart strategy is used to guide .

By analyzing the causes that shaped the economic development gap between the western and eastern regions, this paper proposes an interactive economic development strategy between the two regions through dual opening.
