This Note presents original rates of convergence for the deconvolution problem. We assume that both the estimated density and noise density are supersmooth and we compute the risk for two kinds of estimators. Résumé Vitesses de convergence en déconvolution nonparamétrique. Cette Note présente des vitesses de convergence originales pour le problème de déconvolution. On suppose que la densité est...

Standing dead trees (snags) are an important component of forest ecosystems, providing foraging, nesting, and roosting substrate for a variety of vertebrates. We examined the effects of four forest regeneration treatments on residual snag density and compared those with densities found in unharvested, naturally regenerated forests (controls) during the second, fourth, and sixth year after timbe...

Inventories of the necromass of coarse woody debris typically involve measurements of density (e.g., kilograms per cubic metre) on a sample of logs, with densities of other logs estimated based on assignment to decay classes. Here, we compare two new devices for assessing density of woody debris, a spring penetrometer and a dynamic penetrometer, with the traditional decay classification and kni...

Red alder (Alnus rubra Bong.) seedlings were planted in northwestern Oregon, U.S.A., at five initial spacings: 0.6 × 1.2 m, 1.2 × 1.2 m, 1.2 × 1.8 m, 1.8 × 1.8 m, and 2.5 × 2.5 m. Up to about age 10, tree and stand characteristics were correlated primarily with initial planting density in the expected manner; through age 20, however, tree growth and stand development in plots planted at rectang...

Fluvial geomorphic processes structure habitats important to stream fishes. We determined relationships between densities of smallmouth bass (Micropterus dolomieu) and ecoregions, watershed and reach morphology, and stream habitat in eastern Oklahoma, USA. Watershed and reach morphology were measured at 128 stream sites, and stream habitat and smallmouth bass abundance were measured in 1800 cha...

Patient âgé de 56 ans, sans antécédent pathologique particulier, présentait depuis 5 ans une exophtalmie droite (A), progressive, non axile en bas et en dehors, non réductible et indolore. L'examen ophtalmologique trouvait une perception lumineuse négative droite avec une atrophie optique. La tomodensitométrie orbitaire montrait un processus fronto-éthmoïdal de densité osseuse avec une extensio...

EnglishTraditionally, the study of ‘semantic change’ focuses on relationship between meaning an item and representations that can be accessed from this through metaphorical or metonymic extensions, various kinds analogy, which are incorporated for a variable time period in at issue. Considering lexical monosemy has outstanding character frequency use is correlated to variety cotexts it appears ...

In the robust track of the 2008 CLEF evaluation campaign an enlarged English corpus was provided. For each term, the lemma, the part-of-speech (POS) and the Synset number extracted from WordNetTM (class number of the corresponding thesaurus) are given. Based on this corpus we tested several approaches to remove at least partially the underling lexical ambiguity. Using different IR models such a...
