Sur le Monoide Syntactique de L Lorsque L est un Langage Fini

We prove that for every finite monoid M , there exists a finite language L such that M divides the syntactic monoid of L∗. Moreover, one can choose for L a full finite prefix code. The same result for finite group has already been proved by Schützenberger. This result is crucial in the proof of the J.-F. Perrot’s theorem that the only variety closed under star operation is the variety of all ra...

Ostéochondrite du condyle fémoral

L'Ostéochondrite disséquante des condyles fémoraux est une affection rare. Elle se définit comme une zone localisée de modifications vasculaires atteignant l'os sous chondral. La physiopathologie n'est pas connue mais l'hypothèse mécanique et vasculaire reste au premier plan. La classification de Bedouelle permet une analyse précise de la lésion et a un intérêt dans l'indication thérapeutique. ...

The chromosome territory interchromatin compartment (CT-IC) model argues for a functional organization of the cell nucleus. Chromosome territory (CT) arrangements show profound differences between certain cell types. In the spherically shaped lymphocyte nuclei gene dense CTs are preferentially located in the nuclear interior, while gene poor CTs are preferentially located towards the nuclear pe...
