Catanese surfaces are regular surfaces of general type with pg = 0. They specialize to double covers of Barlow surfaces. We prove that the CH0 group of a Catanese surface is equal to Z, which implies the same result for the Barlow surfaces.

We consider a particle of half-integer spin which is nonrelativistic in the rest frame. Assuming the particle is completely polarized along third axis we calculate the Bloch vector as seen by a moving observer. The result for its length is expressed in terms of dispersion of some vector operator linear in momentum. The relation with the localization properties is discussed. ∗supported by the Ló...

Distribution of magnetic fields in the quiet-Sun internetwork areas has been affected by weak polarization (in particular Stokes Q and U) signals. To improve the signal-to-noise ratio (SNR) of the weak polarization signals, several approaches, including temporal integrations, have been proposed in the literature. In this study, we aim to investigate a proper temporal-integration time with which...

Introduction: Prostate cancer (PCa) is the most prevalent malignant tumor in the male population worldwide and it is the second leading cause of cancer-related death in males. PCa is almost incurable due to the resistance of PCa to conventional treatments. Cancer stem cells (CSCs) theory suggests that a small subpopulation of cancer cells is responsible for tumor development, ...

We study the cosmological evolution of the closed universe on a spherical probe brane moving in the AdSm × S background and the near-horizon background of the dilatonic D-branes. The Friedmann equations describing the evolution of the brane universe, and the effective energy density and pressure simulated on the probe brane due to its motion in the curved background spacetime are obtained and a...

RÉSUMÉ. Les séries télévisées récentes multiplient les personnages principaux, développant ainsi des intrigues complexes présentées à travers plusieurs histoires entremêlées. Nous proposons une approche de détection automatique de ces histoires afin de générer un résumé vidéo par extraction de scènes représentatives de ces dernières, et nous présentons un outil de visualisation rapide des histo...

Résumé. Description de Moz, un système d’aide à la traduction conçu pour le traitement de textes structurés ou semi-structurés avec une forte proportion de contenu terminologique. Le système comporte une mémoire de traduction collaborative, qui atteint un niveau élevé de rappel grâce à l’analyse sousphrastique ; il fournit également des dispositifs de communication et de révision. Le système es...
