Drought is a complex phenomenon which can be characterised mainly by its severity, duration and areal extent. Among these three dimensions, drought severity is the key factor which can be used for drought analysis. Drought indices are typically used to assess drought severity in a meaningful way. DrinC (Drought Indices Calculator) is a software package which was developed for providing a simple...

Dryland plant ecosystems tend to exhibit bistable dynamics with two preferential configurations of bare and vegetated soils. Climate fluctuations are usually believed to act as a source of disturbance on these ecosystems and to reduce their stability and resilience. In contrast, this work shows that random interannual fluctuations of precipitation may lead to the emergence of an intermediate st...

The interaction of formaldehyde with Pt/TiO2 and Au/TiO2 catalysts was investigated at 300–473 K by Fourier transform infrared spectroscopy and mass spectrometry. The effects of the pretreatments and the metal content of the catalysts, as well as the effects of the reaction temperature on the formation of the surface species and on the gas phase products were studied. Molecularly adsorbed forma...

SCP1 as a nuclear transcriptional regulator acts globally to silence neuronal genes and to affect the dephosphorylation of RNA Pol ll. However, we report the first finding and description of SCP1 as a plasma membrane-localized protein in various cancer cells using EGFP- or other epitope-fused SCP1. Membrane-located SCP1 dephosphorylates AKT at serine 473, leading to the abolishment of serine 47...

This article introduces a new and effective method for urban zone segmentation in satellite imagery. The proposed method consists in filtering a band of the multi-spectral image (from the SPOT satellite) with a quadrature bandpass isotropic filter. The filter bandwith and tuning frequency are determined from the source images by a simple experimental analysis. The final image can be obtained by...
