This work focuses on a parameter-free joint piecewise smooth image denoising and contour detection. Formulated as the minimization of discrete Mumford–Shah functional estimated via theoretically grounded alternating scheme, bottleneck such variational approach lies in need to fine-tune their hyperparameters, while not having access ground truth data. To that aim, Stein-like strategy providing o...

Cross-cultural psychologists seek to understand the nature of culture, a concept that can only be understood at the collective, supra-individual level. In most areas of psychology, researchers treat each individual as a separate source of data. Crosscultural psychologists therefore need a clear understanding of the relationship between individual-level and group or collective-level analysis. Se...

The processing of fluent speech involves complex computational steps that begin with the segmentation of the continuous flow of speech sounds into syllables and words. One question that naturally arises pertains to the type of syllabic information that speech processes act upon. Here, we used functional magnetic resonance imaging to profile regions, using a combination of whole-brain and explor...

This study aims at examining the accentual and phrasing properties of a variety of L2 French commonly called “Français Fédéral”, a variety of French spoken in Switzerland by speakers who have a Swiss-German dialect as a mother tongue. For this, we compared the data of 4 groups of 4 speakers: 2 groups of 4 native French speakers from Neuchâtel and from Paris, and 2 groups of 4 Swiss-German Frenc...
