We have performed a series of two-dimensional and three-dimensional simulations of asteroid impacts into an ocean using the SAGE code from Los Alamos National Laboratory and Science Applications International Corporation.The SAGE code is a compressible Eulerian hydrodynamics code using continuous adaptive mesh refinement for following discontinuiti
Wild bees are essential pollinators whose survival partly depends on the capacity of their environment to offer a sufficient amount of nectar and pollen.Semi-natural habitats and mass-flowering crops such as oilseed rape provide abundant floristic resources for bees.The aim of this study was to evaluate the influences of the spatial distribution of
In our previous work, a two-phase multiobjective sparse unmixing (Tp-MoSU) approach has been proposed, which settled the regularization parameter issues of the regularization unmixing methods.However, Tp-MoSU has limited performance in identifying the real end-members from the highly noisy data in the first phase and cannot effectively exploit the
