Light pruning and deficit irrigation regimes are practices which are widely used in high yielding commercial vineyards in the warm climate regions of Australia. Little information is available on their impacts on carbohydrate dynamics in vegetative organs within and between seasons, and on the resulting plant capacity to maintain productivity and ripen fruits. This study was conducted to addres...

Any multivariate density can be decomposed through successive conditionings into basic building blocks involving only pairs of variables. The various ways in which this can be done are called regular vines; C-vines and D-vines are prime examples of such structures. A pair-copula construction (PCC) is a modelling strategy in which conditional and unconditional bivariate copula densities are assi...

Background Leaf shape among Passiflora species is spectacularly diverse. Underlying this diversity in leaf shape are profound changes in the patterning of the primary vasculature and laminar outgrowth. Each of these aspects of leaf morphology-vasculature and blade-provides different insights into leaf patterning. Results Here, we morphometrically analyze >3300 leaves from 40 different Passifl...

The growth and yield of Egusi melon in response to application of an Organo-mineral fertilizer was investigated. The Organo-mineral fertilizer was Cow-dung generated from an Abattoir fortified with inorganic Nitrogen. The fertilizer had a pH of 6.1; 61.2 g kg Organic Matter; 35.5 g kg -1 -1 Organic Carbon; 3.6g kg Nitrogen; 372.54 mg kg Available Phosphorus and 14.8cmol kg -1 -1 -1 Exchangeable...

The loss of 1,2-dibromo-3-chloropropane (DBCP) as a postplant nematicide created a serious void in nematode protection for crops nationwide. An acceptable replacement for DBCP is needed, especially on susceptible perennials such as grapes, Vitis vinifera L. Phases of our postplant nematicide research were conducted in commercial vineyards where nematode disease existed on established vines wate...

Vine copula is an important tool in modeling dependence structures of continuousvalued random variables. The maximum likelihood estimation (MLE) for vine copulas has long been considered computationally difficult in higher dimensions, even in 10 or 20 dimensions. Current computational practice, including the implementation in the state-ofthe-art R package VineCopula, suffers from the bottleneck...

A novel color-based recording and evaluation technique is presented which allows to determine the spatial distribution of foliage along approximately planar vine rows with high accuracy. The approach uses optical flow tracking to construct a composite from an image sequence and user-trainable bayesian color classification to segment foilage from a distinctively colored canvas carried along behi...

Purpose — This study aims to examine Islamic cryptocurrencies and their dependency on foreign exchange markets in vine copula architecture (CD-Vine) provide a framework for detecting complex dependence structures, risk management implications, hedging effectiveness.
 Design/Methodology/Approach used gold-backed three fiat currencies. The approach was preferred because it applies several di...
