In this paper possibility of creating a medium based on graphene-dielectric structures with the hyperbolic shape wave number dispersion is considered for the case when two types of graphene sheets with different chemical potentials periodically alternate.Using the Bloch theorem and the transfer matrix method, dispersion relations for the light wave
Interactive techniques for extracting the foreground object from an image have been the interest of research in computer vision for a long time.This paper addresses the problem of an efficient, semi-interactive extraction of a foreground object from an image.Snake Compressor Motor Overload Cutout (also known as Active contour) and GrabCut are two p
Abstract Background Numerous megafauna species from northern latitudes went extinct during the Pleistocene/Holocene transition as a result of climate-induced habitat changes.However, several ungulate species managed to successfully track their habitats during this period to eventually flourish and recolonise the holarctic regions.So far, the genomi
Much of Body Creams the popular debate that surrounds no platforming centres on its putatively corrosive impact on free speech.This is apt to give a misleading picture of the particular puzzle that no platforming presents.Focusing on the university specifically, I contend that no platforming is distinctively objectionable not because it necessarily
