The LivDet-2020 competition focuses on Presentation Attacks Detection (PAD) algorithms, has still open problems, mainly unknown attack scenarios. It is crucial to enhance PAD methods. This can be achieved by augmenting the number of Attack Instruments (PAI) and Bona fide (genuine) images used train such algorithms. Unfortunately, capture creation PAI even are sometimes complex achieve. generati...

ABSTRACT In this paper, we revisit the problem of identifying bona fide cluster Cepheids by performing an all-sky search for associated with open clusters and making use state-of-the-art catalogued information both clusters, based on unparalleled astrometric precision second early third data releases Gaia satellite. We determine membership probabilities following a Bayesian approach using spati...

Bacterial regulatory RNAs have been extensively studied for over a decade, and are progressively being integrated into the complex genetic regulatory network. Transcriptomic arrays, recent deep-sequencing data and bioinformatics suggest that bacterial genomes produce hundreds of regulatory RNAs. However, while some have been authenticated, the existence of the others varies according to strains...

Although stroma-filled extensions and protrusions of the plastid envelope called stromules were described as long as a century ago, only recently with the advent of fluorescent protein technology have they become widely accepted as bona fide structures of chloroplasts and plastids. Stromules usually occur as filamentous tubules that can be up to 50 to 60 mm in length. The rediscovery of plastid...
