Since every plane-harmonic function is associated with a conjugate, problems in which normal gradients are specified on the boundary can be transformed into problems in which boundary values are ...

We propose a new decomposition method for large-scale linear programming. This method dualizes an (arbitrary) subset of the constraints and then maximizes the resulting dual functional by dual ascent.

Relaxation techniques may help lower high blood pressure-at least in the short term-but the longer term effects are unclear, finds a pooled data analysis of the existing research published in the open ...
