We study the problem of sparse recovery in context compressed sensing. This is to minimize sensing error linear measurements by vectors with at most s non-zero entries. develop so-called critical point theory for recovery. done introducing nondegenerate M-stationary points which adequately describe global structure this non-convex optimization problem. show that all are generically nondegenerat...

As a representative of the Frankfurt School, Marcuse has repeatedly discussed relationship between technology and freedom. He attributes human alienation to fact that technological rationality become covered ideology in developed industrial society, thus making people lose negativity, transcendence criticism, then 'one-dimensional '. This paper takes Marcuse's "comfortable non-freedom" as start...

The recent rise of populism has generated a resurgence interest in critical theory, the wider public debate and academia—with theory being variously accused paving way for post-truth politics, hailed as explaining populism, or criticized failing to achieve its emancipatory political goals. Failure latter kind, many International Relations scholars argue, calls fundamental reform if it is addres...

This paper is devoted to the spectral theory (more precisely, tothe variational theory of the spectrum) of guided waves in anelastic half cylinder.  We use variational methods to investigateseveral aspects of propagating waves, including localization (seeFigure 1), existence criteria and the formulas to find them. Weapproach the problem using two complementary methods: Thevariational methods fo...
