We study semidefinite programming (SDP) relaxations for the NP-hard problem of globally optimizing a quadratic function over the Stiefel manifold. We introduce a strengthened relaxation based on two recent ideas in the literature: (i) a tailored SDP

It is well known that the convex hull of $$\{{(x,y,xy)}\}$$ , where (x, y) is constrained to lie in a box, is given by the reformulation-linearization technique (RLT) constraints. Belotti et al. (Electron Notes Discrete Math 36:805–812, 2010) and M

During our on-going attempts to develop a new skin-whitening agent, we identified a novel candidate compound KHG22394, a 2-imino-1,3-thiazoline derivative. Our data show that KHG22394 significantly inhibits melanin production in a dose-dependent mann

The combination of indole-3-acetic acid (IAA) and horseradish peroxidase (HRP) has recently been proposed as a novel cancer therapy. However, the mechanism underlying the cytotoxic effect involved is substantially unknown. Here, we show that IAA/HRP
