Spatial inhomogeneous
Web27. jún 2024 · In the ecological environment, the space is often inhomogeneous, and the spatial diffusion often occurs in population. Therefore, the reaction–diffusion equation may be more realistic when we study the predator–prey model.

Web1. jún 2012 · We study the spatial behavior of a deflected beam in a coherent Λ-type three-level atomic medium with an inhomogeneous control laser. When the Rabi coupling by the control laser is in a Gaussian profile, the spatial-dependent refraction index of the atomic medium will result in a beam splitting as well as the deflection of the slow probe light …
Web17. jan 2024 · The analyses of spatially resolved EL images reveal the inhomogeneous distribution of luminescence efficiency of the perovskite layer. A significant decrease of ~ 33% in power conversion efficiency (PCE) from 12.15 to 8.15% is found after applying a bias voltage larger than the open-circuit voltage ( Voc) for ~ 60 min in the ambient environment.
