In recent years great strides have been made in improving the accuracy of recommender systems from the point-of-view of their ability to predict users’ ratings for unrated content given a database of past ratings. In a context where the system should ultimately recommend a list of items to the end-user, such accurate rating predictions can be seen as just one possible input into the decision sy...

Bacterial microcompartments (MCPs) are sophisticated protein-based organelles used to optimize metabolic pathways. They consist of metabolic enzymes encapsulated within a protein shell, which creates an ideal environment for catalysis and facilitates the channeling of toxic/volatile intermediates to downstream enzymes. The metabolic processes that require MCPs are diverse and widely distributed...
