A 2-year study was conducted to evaluate ecophysiological characteristics and yield±quality performance of cv. `̀ Aglianico'' (Vitis vinifera L.) grapevines trained to three different trellises at the same intrarow vine spacing and bud load per meter of row length. Bilateral guyot (BG) showed the lowest vine capacity and bilateral spur-pruned cordon (BSPC), with a vertical shoot positioning had ...

This paper attempted to apply an EVT-based pairwise copula method for modelling risk interaction between foreign exchange rates and equity indices of the Johannesburg Stock Exchange (JSE) model dependence structure underlying assets with some selected listed stock indices. We filtered return residuals using stochastic volatility GJR-GARCH (1,1) models different distributions, we best-fitted in ...

Abstract Estimation of instantaneous peak discharge is important in the design hydraulic structures and reservoir management. In this study, a new approach called CEEMD-Copula-GARCH presented for simulating Qale Shahrokh basin, upstream Zayanderood Dam, Iran. developed method, Complementary ensemble empirical mode decomposition (CEEMD) algorithm was used to analyze observed values generate intr...

During the last two decades the advent of fast computers has made Bayesian inference based on Markov Chain Monte Carlo (MCMC) methods very popular in many fields of science. These Bayesian methods are good alternatives to traditional maximum likelihood (ML) methods since they often can estimate complicated statistical models for which a ML approach fails. In this paper we review available MCMC ...

Distribution of the nematode community in a California vineyard was studied over a 13-month period. Omnivorous and microbivorous nematodes were similarly distributed in the root zone, with greatest densities occurring between vine rows and near the soil surface. Greatest densities of plant-parasitic nematodes were found in the vine row, with the individual species differing in their vertical di...

The widely used mean-variance criteria is actually not the optimal solution for asset allocation as the joint distribution of asset returns are distributed in asymmetric ways rather than in the assumed normal distribution. It is a computationally challenging task to model the asymmetries and skewness of joint distributions of returns in high dimensional space due to their own complicated struct...

Tail dependence and conditional tail dependence functions describe, respectively, the tail probabilities and conditional tail probabilities of a copula at various relative scales. The properties as well as the interplay of these two functions are established based upon their homogeneous structures. The extremal dependence of a copula, as described by its extreme value copulas, is shown to be co...

Introduction: Mitral stenosis is a prevalent valvular disease in developing countries. Percutaneous mitral balloon valvuloplasty (PMBV) is the gold standard treatment. The main objective of this study was to assess the initial results of PMBV in patients with mitral stenosis during 16 years (2002-2018) in Mashhad, Iran. Materials and Methods: From April 2002 to March 2018, 770 patients underwen...
