A Multi-Scale Comparison of Heat Stress Metrics in Lyon using meteorological, reanalysis and remote sensing datasets Open
Heat extremes significantly impact human health, causing heat stroke, reduced productivity, and heat-related mortality. In Europe, the increasing frequency of intense heat waves results from a combination of natural climate variability and…
Information gain-based selection of sequential patterns extracted from partial unimodal probabilistic bases of sequences Open
The uncertainty of symbolic data can be represented by probability mass functions.Numerous work adopt this approach to characterize the uncertainty of the events forming a probabilistic base of sequences and extract sequential patterns und…
Exploring an unsupervised data mining approach to extract aseismic slip events along the Izmit section of the North Anatolian Fault, based on FLATSIM time series Open

Predicted Impacts of Booster, Immunity Decline, Vaccination Strategies, and Non-Pharmaceutical Interventions on COVID-19 Outcomes in France Open
The major economic and health consequences of COVID-19 called for various protective measures and mass vaccination campaigns. A previsional model was used to predict the future impacts of various measure combinations on COVID-19 mortality …
Expected Evolution of COVID-19 Epidemic in France for Several Combinations of Vaccination Strategies and Barrier Measures Open
The outbreak of the SARS-CoV-2 virus, enhanced by rapid spreads of variants, has caused a major international health crisis, with serious public health and economic consequences. An agent-based model was designed to simulate the evolution …
Adapting French COVID-19 vaccination campaign duration to variant dissemination Open
The outbreak of SARS-CoV-2 virus has caused a major international health crisis with serious consequences in terms of public health and economy. In France, two lockdown periods were decided in 2020 to avoid the saturation of intensive care…
Adapting French COVID-19 vaccination campaign duration to variant dissemination Open
Background The outbreak of SARS-CoV-2 virus has caused a major international health crisis with serious consequences in terms of public health and economy. In France, two lockdown periods were decided in 2020 to avoid the saturation of int…
Lessons learnt from the use of compartmental models over the COVID-19 induced lockdown in France Open
Background: Compartmental models help making public health decisions. They were used during the COVID-19 outbreak to estimate the reproduction numbers and predict the number of hospital beds required. This study examined the ability of clo…

STUDYING EVOLUTION OF HYDROTHERMAL ALTERATION MATERIALS IN THE TURRIALBA VOLCANO TROUGH MULTISPECTRAL AND HYPERSPECTRAL IMAGES Open
The aim of this work is to develop a geospatial methodology for the analysis of the time evolution of The Turrialba volcano using different automatic imaging techniques compared to expert-based remote sensing techniques. Change detection o…
Piecewise estimation of R0 by a simple SEIR model. Application to COVID-19 in French regions and departments until June 30, 2020 Open
The estimation of R0, the so-called "basic reproductive ratio", of the COVID-19 pandemic is of particular importance to help decision-makers take the necessary safeguard measures to protect the population. In this work, we examine a method…

A Pattern-Based Method For Handling Confidence Measures While Mining Satellite Displacement Field Time Series: Application to Greenland Ice Sheet and Alpine Glaciers Open
For more than 40 years, Earth observation satellites have been regularly providing images of glaciers that can be used to derive surface displacement fields and study their dynamics. In the context of global warming, the analysis of Displac…
