Vine (1971) examines different geometrical spacings of prey in order to determine their risk of visual detection and pursuit by a predator. In his first model, Vine considers a situation where there are n prey (es), each of body length I and all at a distance r from some predator P. This predator can detect a prey (occupying Z/r radians) if that prey is standing completely within 8, radians in ...

The influence of postharvest fruit ripening in the composition of metabolites, transcripts and enzymes in tomato (Solanum lycopersicum L.) is poorly understood. The goal of this work was to study the changes in the metabolite composition of the tomato fruit ripened off-the-vine using the cultivar Micro-Tom as model system. Proton nuclear magnetic resonance (1H NMR) was used for analysis of the ...

Vine copula, constructed from bivariate copulas, provides great flexibility in modelling complex high-dimensional dependence. When applied to multi-population mortality modelling, vine copula yields significant improvement over traditional multivariate copulas. In this paper, we propose capture time-varying features dependence with dynamic regular (R-vine) which is built copulas parameters. We ...

Motivation: Science Gateways are web portal environments targeted for given community and dedicated to the specific scientific domain. End users require different set of tools, applications, data integration patterns to be able to satisfy special demands of different kind of scientific research approach. To let users benefit from computational resources and storage, a portal framework should su...

The aim of this study was to investigate the influence of vine water status on bouquet typicality, revealed after aging, and the perception of three aromatic notes (mint, truffle, and undergrowth) in bottled fine red Bordeaux wines. To address the issue of the role of vine water deficit in the overall quality of fine aged wines, a large set of wines from four Bordeaux appellations were subjecte...

A good pairing is based on the complementary role of wine on the four important factors of food: components, textures, flavors and colors. Common wine and food examples of food preparation with wine or vine products, such as grapes or vine leaves, exemplify numerous similarities and contrasting characteristics in those four parameters, which we can find in an enjoyable meal. The knowledge of th...

This paper features an application of Regular Vine copulas which are a novel and recently developed statistical and mathematical tool which can be applied in the assessment of composite financial risk. Copula-based dependence modelling is a popular tool in financial applications, but is usually applied to pairs of securities. By contrast, Vine copulas provide greater flexibility and permit the ...

Wine grape quality and quantity are affected by vine growing conditions during critical phenological stages. Field observations of vine growth stages are too sparse to fully capture the spatial variability of vine conditions. In addition, traditional grape yield prediction methods are time consuming and require large amount grape samples. Remote sensing data provide detailed spatial and tempora...
