Le paradigme d’Uppsala : la distance géographique et l’effet de réseau comme déterminants des décisions d’acquisitions internationales (1990-2009) [PDF]
, 2010 L’objectif de cet article est de tester la validité du modèle d’Uppsala, dans sa version de 1977 puis dans sa version de 2009. À cette fin, nous étudions la distance géographique et l’effet de réseau comme déterminants des décisions d ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Variations morphologiques, syntaxiques, sémantiques et Repérage d’Information sur le Web [PDF]
, 2003 Le repérage d’information sur le Web présente des défis particuliers, en raison de la grande variété de domaines, genres et styles des documents (ce qui augmente les phénomènes de polysémie, d’homonymie et de synonymie), et des types de requêtes ...

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Dynamic inefficiency with a decreasing returns technology for firms [PDF]
In this paper, we highlight the possibility of dynamically inefficient equilibria in a model with strictly convex production function at the firm’s level. Decreasing returns imply the existence of some pure profit and hence of an asset market.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
