Retrospective Mapping of Global Snow and Ice Cover Beyond the Satellite Observational Era
Earth and Space Science, Volume 12, Issue 5, May 2025.Abstract Monitoring Earth's snow and ice cover is essential for diverse applications, including climate studies, hydrological forecasting, and precipitation mapping. This study develops and evaluates methodologies to extend the Global Multisensor Automated Snow and Ice Mapping System (GMASI) records prior to its July 1987 inception, reconstructing high‐

The Dunkl convolution operators and multipoint de la Vallee–Poussin problem
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2013 The Dunkl operator as an object of mathematical physics is considered, we study the kernel and the surjectivity of Dunkl convolution operators in the space of entire functions and the space of entire functions of exponential type.

RACAR : Revue d'art canadienne, 2020 Pourquoi si peu d’historiennes d’art ont-elles analysé les oeuvres du Poussin ? Nous tenterons de répondre à cette question en considérant comment les articulations de la sexualisation ont informé et continuent d’informer la construction des discours sur Poussin.

Journal of Plant Nutrition and Soil Science, Volume 188, Issue 2, Page 299-311, April 2025.ABSTRACT Background During the last decades, gamma spectrometry data have increasingly been used in soil science, for example, for mapping. However, the full data potential could not be exploited due to certain constraints, among which the insufficient representation of attenuating materials (in particular, water) in correction algorithms is the most ...

Journal of Applied Ecology, Volume 62, Issue 1, Page 119-131, January 2025.Our findings illustrate the shifting importance of natural and agricultural wetlands for godwits at different stages of the nonbreeding season. Protected areas in the Senegal Delta, particularly the Djoudj National Bird Sanctuary (Senegal) and Diawling National Park (Mauritania), are crucial habitats during the dry season as godwits prepare for their ...
