Testing the limits of applicability quantum mechanics will deepen our understanding universe and may shed light on interplay between gravity. At present there is a wide range approaches for such macroscopic tests spanning from matter-wave interferometry large molecules to precision measurements heating rates in motion micro-scale cantilevers. The “displacemon” proposed electromechanical device ...

We study a class of large-scale, nonsmooth, and nonconvex optimization problems. In particular, we focus on nonconvex problems with composite objectives. This class includes the extensively studied class of convex composite objective problems as a subclass. To solve composite nonconvex problems we introduce a powerful new framework based on asymptotically nonvanishing errors, avoiding the commo...

The UN sustainable development goals contain environmental, economic, and social objectives. They may only be reached, or at least it would be easier to reach them, if instead of a trade-off between these objectives that implies a need for balancing them, there are synergies to be reaped. This paper discusses how the structures of economic models typically used in policy analysis influence whet...
