Cosmologies, singularities and quantum extremal surfaces

Abstract Following [1], we study quantum extremal surfaces in various families of cosmologies Sculpture with Big-Crunch singularities, by extremizing the generalized entropy in 2-dimensional backgrounds which can be thought of as arising from dimensional reduction.Focussing first on the isotropic AdS Kasner case, introducing a spatial regulator ena

Dynamic evolution and scenario simulation of habitat quality under the impact of land-use change in the Huaihe River Economic Belt, China.

Habitat quality is an important indicator for evaluating the biodiversity provided by ecosystem.Estimating and scenario-simulating the dynamic evolution and future development trends of habitat quality under the influence of land-use change is significant in regional biodiversity conservation, formulating land-use planning, and maintaining the ecol
