Macromolecular structure solution by charge flipping [PDF]
Acta Crystallographica Section A Foundations of Crystallography, 2008 The recently discovered charge-flipping phasing algorithm has received growing interest in small-molecule crystallography and powder diffraction. This computational methodology differs from classical direct methods as it does not require a priori knowledge of either space-group symmetry or chemical composition and does not rely on probabilistic phase ...

On invariant structures of black hole charges [PDF]
Journal of High Energy Physics, 2012 Abstract We study “minimal degree” complete bases of duality- and “horizontal”- invariant homogeneous polynomials in the flux representation of two-centered black hole solutions in two classes of D = 4 Einstein supergravity models with symmetric vector multiplets’ scalar manifolds. Both classes exhibit an SL(2,
