Performances des colonnes en béton confiné avec des enveloppes externes en composites « PRFC »
, 2011 Un programme expérimental comprenant des essais sur 30 cylindres 160x320 mm a été mené en vue de déterminer le gain de résistance et de ductilité du béton confiné par collage externe de tissu de polymère renforcé de fibres de carbone (PRFC). Les variables étudiées sont la résistance à la compression du béton non confiné f’co, le niveau de confinement ...

Compression-Based Compressed Sensing
, 2016 Modern compression algorithms exploit complex structures that are present in signals to describe them very efficiently. On the other hand, the field of compressed sensing is built upon the observation that "structured" signals can be recovered from their

Breaking the cycle of socioeconomic disadvantage: Parental reflexivity and motivation for change
Family Relations, Volume 75, Issue 1, Page 535-554, February 2026.Abstract Objective The goal was to deepen the understanding of parental reflexivity by examining the relationship between its components and their association with parental motivation to engage in interventions, while analyzing professionals' expectations and perceptions of families' progress, in socioeconomically disadvantaged contexts.

Identification of the prfC gene, which encodes peptide-chain-release factor 3 of Escherichia coli. [PDF]
Proceedings of the National Academy of Sciences, 1994 The termination of protein synthesis in bacteria requires two codon-specific polypeptide release factors, RF-1 and RF-2. A third factor, RF-3, which stimulates the RF-1 and RF-2 activities, was originally identified in Escherichia coli, but it has received little attention since the 1970s.
