A product of two Riemann surfaces of genuses p1 and p2 solves the Seiberg-Witten monopole equations for a constant Weyl spinor that represents a monopole condensate. Self-dual electromagnetic fields require p1 = p2 = p and provide a solution of the euclidean Einstein-MaxwellDirac equations with p − 1 magnetic vortices in one surface and the same number of electric vortices in the other. The mon...

No nontrivial software system can be built without regard for security. Even noncritical systems used as an entry point to the critical which they are connected, example, exploiting vulnerabilities steal passwords login and network access. This article describes one such attack.
