Severity of Compound Precipitation and Temperature Extreme Events Over Africa at 1.5°C and 2°C Global Warming Levels

open access: yesInternational Journal of Climatology, EarlyView.
Results indicate that, an increase in global warming level from 1.5°C to 2°C is likely to induce on the one hand a 3‐fold increase in the frequency of occurrence of dry and warm compound events, and on the other hand a 2‐fold increase in their duration, over West, Central, South‐West, and South‐East Africa, intensifying droughts through reduced ...

Automated Imaging of Cultured Bacteria in Picoliter Droplets by Coherent Anti‐Stokes Raman Scattering and Two‐Photon Excited Fluorescence Microscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
We present an automated system that combines an image‐based fuzzy logic controller for precise positioning of microfluidic picoliter droplets with nonlinear microscopy, using CARS and TPEF modalities for detailed analysis of droplet composition. Time series and z‐stack images of E. coli, B. subtilis, and M. arborescens were recorded.
