Feature selection for ensembles has shown to be an effective strategy for ensemble creation due to its ability of producing good subsets of features, which make the classifiers of the ensemble disagree on difficult cases. In this paper we present an ensemble feature selection approach based on a hierarchical multi-objective genetic algorithm. The algorithm operates in two levels. Firstly, it pe...

Protein-peptide interactions are vital for the cell. They mediate, inhibit or serve as structural components in nearly 40% of all macromolecular interactions, and are often associated with diseases, making them interesting leads for protein drug design. In recent years, large-scale technologies have enabled exhaustive studies on the peptide recognition preferences for a number of peptide-bindin...

Size selection was demonstrated to suppress Ostwald ripening of supported catalytic nanoparticles. When the clusters are subnanometer in size and highly fluxional, such as Pt on rutile TiO2(110) surface, this paradigm breaks down, established theory sintering needs a revision. At temperatures characteristic catalysis (i.e. 700 K), sub-nano thermally populate many low-energy metastable isomers. ...
