Atteinte cutanée et nasale: ne pas méconnaitre la sarcoïdose

La sarcoïdose est une maladie granulomateuse systémique d'éthiopathogénie inconnue. Les localisations ORL sont rares. Le traitement médical de la sarcoïdose nasale doit être administré précocement afin de prévenir l'évolution vers une fibrose locale. Nous rapportons l'observation d'un homme âgé de 50 ans, sans antécédents particuliers, ayant présenté un érythème facial, une obstruction nasale b...

Simultaneous Quanti

We present a sequent calculus which allows the simultaneous elimination of multiple quantiiers. The approach is an improvement over the well-known skolemization in sequent calculus. It allows a lazy handling of instantiations and of the order of certain reductions. Simultaneous quantiier elimination is justiied from a semantical as well as from a proof theoretical point of view.

Labelled quanti ed modal

We present an approach to providing natural deduction style proof systems for a large class of quantiied modal logics with varying, increasing, decreasing or constant domains of quantiication. The systems we develop are modular both in the behavior of the accessibility relation and quantiication relative to the semantics, and in the proofs of soundness and completeness relative to that semantic...

Generalized Quanti ers

We considered the problem of processing queries that contain generalized quanti ers. We demonstrate that current relational systems are ill-equipped, both at the language and at the query processing level, to deal with such queries. We propose a boolean matrix approach which establishes the feasibility of building systems that can process queries with generalized quanti ers e ciently, and we pr...
