Vegetation patterns pinpoint the least resilient dryland sites

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 1, Page 172-187, January 2026.
Abstract Resource‐limited ecosystems, such as drylands, can exhibit self‐organized spatial patterns. Theory suggests that changes in these patterns can inform about the ecosystem degradation level. While the current theory is expected to work well when following a given site in time, we still lack ways of comparing different field sites using static ...

Logique et mathématiques chez Hegel. Les formalisations de la logique en question

open access: yesMosaïque, 2013
Quoi qu’on n’ignore pas les développements importants et positifs que Hegel consacre à la mathématique de l’infini, aux calculs différentiel et intégral, son discours est dans l’ensemble très sévère à l’égard des mathématiques. Pour l’expliquer,

A multiscale growth atlas of Arabidopsis: linking cell dynamics to organ development

open access: yesNew Phytologist, Volume 249, Issue 1, Page 299-324, January 2026.
Summary Plant development depends on coordinated growth at cellular and organ scales, yet comparative analyses are hindered by inconsistent reporting of growth across studies. We conducted a meta‐analysis of Arabidopsis thaliana growth dynamics, integrating data from 176 studies to create the first multiscale atlas of plant growth.

Predicting financial markets with Google Trends and not so random keywords

open access: yes, 2013
We check the claims that data from Google Trends contain enough data to predict future financial index returns. We first discuss the many subtle (and less subtle) biases that may affect the backtest of a trading strategy, particularly when based on such ...

The quenched limiting distributions of a one-dimensional random walk in random scenery

open access: yes, 2013
For a one-dimensional random walk in random scenery (RWRS) on Z, we determine its quenched weak limits by applying Strassen's functional law of the iterated logarithm. As a consequence, conditioned on the random scenery, the one-dimensional RWRS does not
