Journal ArticleDOI
Retinal vessel segmentation by improved matched filtering: evaluation on a new high-resolution fundus image database
Jan Odstrcilik,Radim Kolar,Attila Budai,Joachim Hornegger,Jiri Jan,Jiri Gazarek,Tomas Kubena,Pavel Cernosek,Ondrej Svoboda,Elli Angelopoulou +9 more
TL;DR: The concept of matched filtering is improved, and the proposed blood vessel segmentation approach is at least comparable with recent state-of-the-art methods, and outperforms most of them with an accuracy of 95% evaluated on the new database.
Journal ArticleDOI
Point defects stabilise cubic Mo-N and Ta-N
TL;DR: In this article, the authors employed ab initio calculations to investigate the energetics of point defects in metastable rocksalt cubic Ta-N and Mo-N, and showed that defect-ordered structures are more stable than perfect ones with metal-to-nitrogen stoichiometry.
Journal ArticleDOI
Clonal analysis of hematopoietic progenitor cells in the zebrafish.
David L. Stachura,Ondrej Svoboda,Ryan P. Lau,Keir M. Balla,Leonard I. Zon,Petr Bartunek,David Traver +6 more
TL;DR: These experiments provide the first report of clonal hematopoietic progenitor assays in the zebrafish and establish the number, characteristics, and kinetics of myeloerythroid progenitors during both steady-state and stress hematoiesis.
Journal ArticleDOI
Reaction selectivity in an ionized water dimer: nonadiabatic ab initio dynamics simulations.
TL;DR: The main goal of this study is to find out whether a state-dependent reactivity is observed for the water dimer radical cation, and provides a detailed mapping of the potential energy surfaces (PESs) in the relevant coordinates for different electronic states.
Journal ArticleDOI
Electrically switchable magnetic molecules: inducing a magnetic coupling by means of an external electric field in a mixed-valence polyoxovanadate cluster.
Salvador Cardona-Serra,Juan M. Clemente-Juan,Eugenio Coronado,Alejandro Gaita-Ariño,Nicolas Suaud,Ondrej Svoboda,Roland Bastardis,Nathalie Guihéry,Juan Jose Palacios +8 more
TL;DR: The results emphasize that the sharp spin transition induced by the electric field in the V14 system is a robust phenomenon, intramolecular in nature, and barely influenced by small changes on the external structure.
