We complete the theory of velocity averaging lemmas for transport equations by studying the limiting case of a full space derivative in the source term. Although the compactness of averages does not hold any longer, a speciic estimate remains, which shows compactness of averages in more general situations than those previously known. Our method is based on Calderon-Zygmund theory. R esum e Nous...

Nous étudions les sommes des valeurs propres opérateurs de Hecke formes paraboliques Hecke–Maass pour le groupe SL(n,ℤ) avec n≥3 quelconque, sur intervalles courts d’une certaine longueur, en admettant l’hypothèse Lindelöf généralisée et une estimation l’exposant direction la conjecture Ramanujan–Petersson, un peu plus forte que celle qui est actuellement connue. En particulier, dans cette situ...

A study was conducted on 136, nonna\, French speaking, independent adults in good health. Subjects were between 25 and 85 years of age, had a minimum of 4 years of education, and were divided into nine groups based on education and age. They were administered a naming task comprised of 40 monosyllabic, 40 bisyllabic, and 40 polysyllabic words. An analysis of variance on correct responses reveal...

We describe an experiment demonstrating XUV amplification following collisional excitation in a capillary discharge plasma irradiated by a picosecond IR laser pulse. Guiding and temporally resolved transmission of the pump laser beam are also demonstrated and analysed. The short pump laser pulse heated rapidly the electrons producing amplification in the 3pS0–3sP1 transition of Ne-like sulphur ...

Les services écosystémiques fournis par la faune du sol sont primordiaux à mise en place d’une agriculture écologiquement intensive. L’hinterland de ville Kikwit RD Congo est caractérisé des sols pauvres, acides et peu fertiles. Ainsi, cette étude avait pour objectif, l’amélioration productivité production l’inoculation vers terre. résultats obtenus ont montré que terre peut être assurée les dé...

La prise en charge périopératoire des urgences chirurgicales abdominales reste une préoccupation majeure des anesthésistes du fait des désordres hémodynamiques et/ou métaboliques souvent présents en préopératoire ; mais également des complications postopératoires auxquelles elles sont exposées. Les objectifs de ce travail étaient d'étudier les aspects épidémiologiques, diagnostiques, thérapeuti...

In many long-lived species such as Arctic grayling (Thymallus arcticus), population growth rate is most sensitive to changes in adult survival probabilities. Understanding the factors that regulate adult survival in this species should provide insight into the population dynamics of this and other long-lived Arctic species. Using the program MARK, we analyzed 17 years of mark–recapture data to ...

The paper investigates the long time average of the solutions of Hamilton-Jacobi equations with a non coercive, non convex Hamiltonian in the torus R2/Z2. We give nonresonnance conditions under which the long-time average converges to a constant. In the resonnant case, we show that the limit still exists, although it is non constant in general. We compute the limit at points where it is not loc...

We compared annual basal area increment (BAI) at different spatial scales among all size classes and species at diverse locations in the wet western and dry northeastern Olympic Mountains. Weak growth correlations at small spatial scales (average R = 0.084–0.406) suggest that trees are responding to local growth conditions. However, significant positive growth correlations between geographicall...
