Identifying the pedoclimatic conditions most critical in the susceptibility of a grapevine cultivar to esca disease Open

Valérie Hofstetter, Vinciane Monod, Matthieu Wilhelm, Olivier Viret, Katia Gindro , et al. · 2025

Esca, one of the most destructive grapevine trunk diseases, is still poorly understood. As grapevine cultivars vary widely in their susceptibility to esca, we designed a four-year experiment to identify the environmental factors that influ…

Occurrence of <i>Aspergillus fumigatus</i> azole resistance in soils from Switzerland Open

Stéphanie Schürch, Katia Gindro, Sylvain Schnée, Pierre‐Henri Dubuis, Josep Massana‐Codina , et al. · 2023

Aspergillus fumigatus is a fungal species causing diverse diseases in humans. The use of azoles for treatments of A. fumigatus diseases has resulted in azole resistance. Azoles are also widely used in the environment for crop protection, w…

A systemic approach allows to identify the pedoclimatic conditions most critical in the susceptibility of a grapevine cultivar to esca/Botryosphaeria dieback Open

Vinciane Monod, Vivian Zufferey, Matthieu Wilhelm, Olivier Viret, Katia Gindro , et al. · 2023

Esca and/or Botryosphaeria dieback (esca-BD) are two of the most destructive grapevine trunk diseases in the world, disease complex which remains poorly understood. As some vine cultivars show highly variable susceptibility to esca-BD, we …

Optimal sequential sampling design for environmental extremes Open

Raphaël de Fondeville, Matthieu Wilhelm · 2021

The Sihl river, located near the city of Zurich in Switzerland, is under continuous and tight surveillance as it flows directly under the city's main railway station. To issue early warnings and conduct accurate risk quantification, a dens…

Sampling Designs on Finite Populations with Spreading Control Parameters Open

Yves Tillé, Lionel Qualité, Matthieu Wilhelm · 2017

We present new sampling methods in finite population that allow to control the joint inclusion probabilities of units and especially the spreading of sampled units in the population. They are based on the use of renewal chains and multivar…

Probability Sampling Designs: Principles for Choice of Design and Balancing Open

Yves Tillé, Matthieu Wilhelm · 2016

The aim of this paper is twofold. First, three theoretical principles are formalized: randomization, overrepresentation and restriction. We develop these principles and give a rationale for their use in choosing the sampling design in a sy…

Quasi-Systematic Sampling From a Continuous Population Open

Matthieu Wilhelm, Yves Tillé, Lionel Qualité · 2016

A specific family of point processes are introduced that allow to select samples for the purpose of estimating the mean or the integral of a function of a real variable. These processes, called quasi-systematic processes, depend on a tunin…

Generalized spatial regression with differential regularization Open

Matthieu Wilhelm, Laura M. Sangalli · 2016

We aim at analysing geostatistical and areal data observed over irregularly shaped spatial domains and having a distribution within the exponential family. We propose a generalized additive model that allows to account for spatially varyin…

IGS: An IsoGeometric approach for smoothing on surfaces Open

Matthieu Wilhelm, Luca Dede’, Laura M. Sangalli, Pierre Wilhelm · 2016

Generalized Spatial Regression with Differential Regularization Open

Matthieu Wilhelm, Laura M. Sangalli · 2015

We aim at analyzing geostatistical and areal data observed over irregularly shaped spatial domains and having a distribution within the exponential family. We propose a generalized additive model that allows to account for spatially-varyin…
