MOTIVATION Progress in large-scale experimental determination of protein-protein interaction networks for several organisms has resulted in innovative methods of functional inference based on network connectivity. However, the amount of effort and resources required for the elucidation of experimental protein interaction networks is prohibitive. Previously we, and others, have developed techniq...

The ever growing applicative importance of correlated materials, such as e.g. magnetic and superconducting oxides, urgently calls for a realistic and affordable description based on first-principles approaches. In this colloquium we review the formulation of pseudo-self-interaction-corrected local-densityfunctional theory (pSIC), and discuss its relation with comparable methods (LDA+U and hybri...
