Tetrahydroxanthenones, which can be easily prepared by a domino oxa-Michael aldol condensation, offer various possibilities for diastereoselective functionalization, giving access to the stereocontrolled synthesis of stereochemical triades or tetrades, which represent privileged structural motifs. In most cases, the relative stereochemistry was unequivocally established by crystal structure ana...

Community detection has become a major active area of research in recent years. A plethora of relevant methods have been implemented for directed graphs. Most of them focus on the density of links, and consider the relationship between nodes as symmetric by ignoring links directionality during their clustering step, this leading to non-semantic results. This paper propose an efficient method ba...

La terrible triade du coude (TTC) est une association lésionnelle à fort potentiel d’instabilité. Le traitement a pour objectif la restitution de stabilité articulaire. réparation ligament collatéral latéral (LCL) doit être systématique, alors que celle médial (LCM) n’est requise qu’exceptionnellement. L’objectif principal cette étude était d’évaluer les résultats cliniques chirurgical des TTC....
