Evaluation of modelling approaches for predicting the spatial distribution of soil organic carbon stocks at the national scale [PDF]
, 2014 Soil organic carbon (SOC) plays a major role in the global carbon budget. It can act as a source or a sink of atmospheric carbon, thereby possibly influencing the course of climate change.

Deep Underground Science and Engineering, EarlyView.This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...

Means and covariance functions for geostatistical compositional data: an axiomatic approach [PDF]
, 2017 This work focuses on the characterization of the central tendency of a sample of compositional data. It provides new results about theoretical properties of means and covariance functions for compositional data, with an axiomatic perspective.
