When designing audio effects for music processing, we are always aiming at providing higherlevel representations that may somehow fill in the gap between the signal processing world and the end-user. Spectral models in general, and the Sinusoidal plus Residual model in particular, can sometimes offer ways to implement such schemes.

Higher education is undergoing radical shifts that are part of the larger wave of changes taking place in our society. The transformation affects all sectors of higher education, especially distance learning and how it relates to the University’s regular offerings. I begin with clarifying the terms commonly associated with distance learning and elaborate on two main instructional models of onli...

We prove general adjoint functor theorems for weakly (co)complete $n$-categories. This class of $n$-categories includes the homotopy $\infty$-categories -- in particular, these do not admit all small (co)limits general. also introduce Brown representability (homotopy) and a theorem localizations compactly generated presentable if $n \geq 2$ stable any 1$.
