We have performed a first-principle calculation of the structural, electronic and high pressure properties of RuSr<Subscript>2</Subscript>GdCu<Subscript>2</Subscript>O<Subscript>8</Sub script>, a ferromagnetic superconductor, by employing a full-potential linearized augmented plane-wave method within the density-functional theory. The effect of pressure was...<//sub></subscript></subscript></subscript>

In the portfolio optimization, the goal is to distribute the fixed capital on a set of investment opportunities to maximize return while managing risk. Risk and return are quantities that are used as input parameters for the optimal allocation of the capital in the suggested models. But these...
