Magic Sets for Data Integration
We present a generalization of the Magic Sets technique to Datalog¬ programs with (possibly unstratified) negation under the stable model semantics, originally defined in (Faber, Greco, & Leone 2005; 2007). The technique optimizes Datalog¬ programs by means of a rewriting algorithm that preserves query equivalence, under the proviso that the original program is consistent. The approach is motiv...
متن کاملThe Not-so-Magic Magic Barrier of Recommender Systems
Recommender Systems need to deal with different types of users who represent their preferences in various ways. This difference in user behaviour has a deep impact on the accuracy of the recommendations received by the users, depending, mostly, on the quantity and the quality of the information the system knows about the user. Specifically, the inconsistencies of the user impose a lower bound o...
متن کاملMagic traits in speciation: 'magic' but not rare?
Speciation with gene flow is greatly facilitated when traits subject to divergent selection also contribute to non-random mating. Such traits have been called 'magic traits', which could be interpreted to imply that they are rare, special, or unrealistic. Here, we question this assumption by illustrating that magic traits can be produced by a variety of mechanisms, including ones in which repro...

The rapid and efficient selection of emotionally salient or goal-relevant stimuli in the environment is crucial for flexible and adaptive behaviors. Converging data from neuroscience and psychology have accrued during the last decade to identify brain systems involved in emotion processing, selective attention, and their interaction, which together act to extract the emotional or motivational v...
