L′interprétation matricielle de la théorie de Markoff classique

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 32, Issue 4, Page 193-262, 2002., 2002
On explicite l′approche de Cohn (1955) de la théorie de Markoff. On montre en particulier comment l′arbre complet des solutions de l′équation diophantienne associée apparasît comme quotient du groupe GL (2, ℤ) des matrices 2 × 2 à coefficients entiers et de déterminant ±1 par un sous‐groupe diédral D6 à 12 éléments.

Bronchial Mucus Properties in Lung Cancer: Relationship with Site of Lesion

open access: yesCanadian Respiratory Journal, Volume 6, Issue 3, Page 246-252, 1999., 1999
OBJECTIVE: To compare the biophysical properties of mucus from the left and right mainstem bronchi in patients undergoing diagnostic bronchoscopy because of a unilateral radiological abnormality. It was hypothesized that abnormalities in the properties of mucus would be greater on the side with the lesion and that this would be most obvious in patients

Du sens du lieu au sentiment d'appartenance

open access: yesCanadian Geographies / Géographies canadiennes, Volume 70, Issue 1, Spring / printemps 2026.
Résumé Malgré qu'on s'intéresse de plus en plus au sens du lieu, il demeure insuffisamment compris dans sa complexité. Le sens d'un lieu varie en effet selon la nature et la portée de nos rapports et interprétations, et donc selon ses fonctions identitaires et nos sentiments à son endroit.

Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) relating to an analysis of the health risks associated with exposure to caterpillars with stinging hairs and the development of management recommendations

open access: yesFood Risk Assess Europe, Volume 3, Issue 2, April 2025.
Abstract Several species of Lepidoptera with caterpillars bearing urticating hairs are increasing their range in metropolitan France from year to year, such as the pine processionary (Thaumetopoea pityocampa Denis et Schiffermüller 1775) whose presence was historically limited to the south of France, and which is gradually being observed in the north ...

Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) on the assessment of the impact of fox population dynamics on public health

open access: yesFood Risk Assess Europe, Volume 3, Issue 2, April 2025.
ABSTRACT The Red Fox (Vulpes vulpes) can be hunted as a game species. It may also be listed as a “species likely to cause damage” (ESOD – the acronym in French), for public health reasons among others. Conversely, benefits linked to the presence of foxes are also put forward, such as the predation of rodents carrying zoonotic agents.
