Abstract:
... Grapevine downy mildew, caused by Plasmopara viticola, is a major disease of cultivated wine grapes in Georgia (USA), where the climate is favorable for rapid epidemic development. Although loss of fungicide sensitivity has been documented for P. viticola populations in other viticultural regions, it had not been confirmed previously in Georgia. Downy mildew samples from three vineyards, two manag ...

Abstract:
... Participatory action research (PAR) is an approach for fully co-creating research into environmental problems with the public. We argue this is mostly done for manifest environmental problems that clearly threaten livelihoods and have highly predictable impacts. But the conventional PAR approach is not suitable when the impacts are poorly understood and pose a low threat to livelihoods. Such laten ...

Abstract:
... The selection of vine structure to represent dependencies in a data set with a regular vine copula model is still an open question. Up to date, the most popular heuristic to choose the vine structure is to construct consecutive trees by capturing largest correlations in lower trees. However, this might not lead to the optimal vine structure. A new heuristic based on sampling orders implied by regu ...

Abstract:
... In many studies multivariate event time data are generated from clusters having a possibly complex association pattern. Flexible models are needed to capture this dependence. Vine copulas serve this purpose. Inference methods for vine copulas are available for complete data. Event time data, however, are often subject to right-censoring. As a consequence, the existing inferential tools, e.g. likel ...

Abstract:
... A rapid Surface Enhanced Raman Spectroscopy (SERS) method to detect SO₂ in wine is presented, exploiting the preferential binding of silver nanoparticles (AgNPs) with sulfur-containing species. This interaction promotes the agglomeration of the AgNPs and inducing the formation of SERS “hot spots” responsible for SO₂ signals enhancement. For increasing SO₂ concentrations from 0 to100 mg/l in wine s ...
