De nombreux fronts se sont ouverts, souvent complémentaires. Front de la programmation : des objets lispiens tels que LeLisp et son inévitable MicroCeyx à Java et C#. Front de la modélisation et du raisonnement : de la première génération de systèmes centrés objets tels Kool, Smeci, FRL ou Sherpa aux règles métiers et aux modèles ontologiques tels que promus par le W3C. Front du Génie Logiciel ...

On a smooth projective threefold, we construct an essentially surjective functor $\mathcal{F}$ from category of two-term complexes to quotients coherent sheaves, and describe the fibers this functor. Under coprime assumption on rank degree, domain coincides with higher-rank PT stable objects, which appear one side Toda's DT/PT correspondence formula. The codomain is objects that another formula...

Although corpus size is a well known factor that affects the performance of many NLP tasks, for many languages large freely available corpora are still scarce. In this paper we describe one effort to build a very large corpus for Brazilian Portuguese, the brWaC, generated following the Web as Corpus kool yinitiative. To indirectly assess the quality of the resulting corpus we examined the impac...

We show that the Quot scheme $\text{Quot}_{\mathbf{A}^3}(\mathcal{O}^r,n)$ admits a symmetric obstruction theory, and we compute its virtual Euler characteristic. extend calculation to locally free sheaves on smooth $3$-folds, thus refining special case of recent characteristic Gholampour-Kool. then Toda's higher rank DT/PT correspondence Calabi-Yau $3$-folds local version centered at fixed slo...

Let $X$ be a Calabi-Yau 4-fold and $D$ smooth divisor on it. We consider tautological complex associated with $L=\mathcal{O}_X(D)$ the moduli space of Le Potier stable pairs define its counting invariant by integrating Euler class against virtual class. conjecture formula for their generating series expressed using genus zero Gopakumar-Vafa invariants one type $X$, which we verify in several ex...

This study finds that participation in extracurricular activities significantly reduces engagement in risky behaviours among Australian adolescents. However, the effects differ by activity type, gender and to some extent by socio-economic status (SES). Participation in activities other than sports and arts reduces both weekly drinking and marijuana use for both genders. Participation in arts re...
