Distributed hash tables suffer from several security and privacy vulnerabilities, including the problem of Sybil attacks. Existing social network-based solutions to mitigate the Sybil attacks in DHT routing have a high state requirement and do not provide an adequate level of privacy. For instance, such techniques require a user to reveal their social network contacts. We design X-Vine, a prote...

The driving force behind the development of rootstocks for nut crops has been the solution of specific problems, often related to the presence of pests or the need for adaptation to particular sites. The use of interspecific hybrids as rootstocks has lead to increased appreciation for the contribution genetic diversity can make to orchard profitability in the face of site specific challenges. T...

A fungus, Colletotrichum fioriniae, was isolated for the first time from fruits of Chinese matrimony vine (Lycium chinense Mill.) in Korea. It was classified as C. fioriniae based on the morphological characteristics and nucleotide sequence of glyceraldehyde-3-phosphate-dehydrogenase and β-tubulin. To the best of our knowledge, this is the first report of C. fioriniae causing anthracnose of Chi...

In Citrus, water, nutrient transport and thereby fruit production, are influenced among other factors, by the interaction between rootstock and boron (B) nutrition. This study aimed to investigate how B affects the anatomical structure of roots and leaves as well as leaf gas exchange in sweet orange trees grafted on two contrasting rootstocks in response to B supply. Plants grafted on Swingle c...

BACKGROUND Grafting is an established practice for asexual propagation in horticultural and agricultural crops. The study on graft unions has become of interest for horticulturists using proteomic and genomic techniques to observe transfer of genetic material and signal transduction pathways from root to shoot and shoot to root. Another reason to study the graft unions was potentially to observ...

petri disease is responsible for grapevine decline and occurs wherever grapevines (vitis vinifera) are cultivated. phaeoacremonium species are among the principal hyphomycetes associated with petri disease. during 2009, a field survey was conducted throughout different vineyards in the fars province of iran in order to determine the fungal pathogens associated with the vine decline observed in ...

BACKGROUND In Castilla-La Mancha, Spain, the area with the highest density of vineyards in the world, 2 cases of Vitis vinifera pollen allergy have been previously reported. OBJECTIVE To determine the clinical relevance and biochemical characteristics of vine pollen in the Spanish province of Ciudad Real. METHODS We designed a prospective study of patients treated in the allergy units from ...

A bivariate copula mixed model has been recently proposed to synthesize diagnostic test accuracy studies and it has been shown that it is superior to the standard generalized linear mixed model in this context. Here, we call trivariate vine copulas to extend the bivariate meta-analysis of diagnostic test accuracy studies by accounting for disease prevalence. Our vine copula mixed model includes...

In recent years analyses of dependence structures using copulas have become more popular than the standard correlation analysis. Starting from Aas, Czado, Frigessi, and Bakken (2009) regular vine pair-copula constructions (PCCs) are considered the most flexible class of multivariate copulas. PCCs are involved objects but (conditional) independence present in data can simplify and reduce them si...
