We prove the hyperbolicity of the complement of five lines in general position in an almost complex projective plane, answering a question by S. Ivashkovich.

Résumé. Cet article présente une méthode complexe pour la caractérisation et l’indexation d’images graphiques de documents anciens. A partir d’un bref état de l’art, une méthode pour décrire ces images en tenant compte de leur complexité est proposée. Trois étapes principales de ce traitement sont détaillées dont une méthode novatrice d’analyse, de segmentation et de description des traits. Les...

High-performance osmotic energy conversion (OEC) requires both high ionic selectivity and permeability in nanopores. Here, through systematical explorations of influences from individual charged nanopore surfaces on the performance OEC, we find that exterior surface low-concentration side (surfaceL) is essential to achieve high-performance power generation, which can significantly improve simul...

Photosystem II (PSII) oxidizes water to produce oxygen through a four-step photocatalytic cycle. Understanding PSII structure-function relations is important for the development of biomimetic photocatalytic systems. The quantum mechanics/molecular mechanics (QM/MM) analysis of substrate water binding to the oxygen-evolving complex (OEC) has suggested a rearrangement of water ligands in a carous...

For the implementation of the Organisation for Economic Co-operation and Development (OEC D) principles of good laboratory practice (GLP) and performance of studies according to worldwide regulatory requirements, test facilities (TFs) in Japan have been making constant effort to promote better understanding of this matter and improve communication with monitoring authorities (MAs). Their activi...
