ABSTRACT We consider a framework for non-ideal magnetohydrodynamics in general relativity, paying particular attention to the physics involved. The discussion highlights connection between microphysics (associated with given equation of state) and global dynamics (from point view numerical simulations), includes careful consideration assumptions that lead ideal resistive magnetohydrodynamics. p...

Abstract Some realists in political theory deny that the notion of feasibility has any place realist theory, while others claim constraints are essential elements normative theorising. But none have so far clarified what exactly they referring to when thinking and realism together. In this article, we develop a conception frontier based on an appraisal how should be distinguished from non-ideal...

Many speech source separation approaches are based on the assumption of orthogonality of speech sources in the time-frequency domain. The target speech source is demixed from the mixture by applying the ideal binary mask to the mixture. The time-frequency orthogonality of speech sources is investigated in detail only for anechoic and artificially mixed speech mixtures. This paper evaluates how ...
