We consider the effects of migration on intraguild predation (IGP) via lattice models and pair approximation. The following results can be found: there exists asymmetry between two consumers’ migration effects on the spatial structure of IGP; migration of each consumer reduces its own clumping...

In this paper, we introduce a non-interacting boson model to investigate the topological structure of complex networks. By exactly solving this model, we show that it provides a powerful analytical tool in uncovering the important properties of realistic networks. We find that the ground-state...

The industry transfer from east region to west region of China has become an inevitable trend of economic development, it need massive agricultural population change to non-agricultural population in China. Based on the redefinition of the citizenization of migrant workers, this article points...

The development of China¡¯s eastern regions shows the characteristic that the industry transfers to inland in recent years. As the developing areas, the western regions of China must resolve an important question which is effectively undertake the various industries from the eastern regions...

Vortex generators (VGs) are commonly-used effective flow separation control devices, and are proved to have potential to improve the aerodynamic performance of large wind turbines. In this paper, the flow physics of VGs and how their size affects the aerodynamic performance of a blunt...

Although China has implemented many air pollution control policies, its air pollution problems remain severe with rapid economic development. The strategy of controlling single pollutant in one period and adding another in the next period (i.e., gradual control strategy) adopted in China has...
