Several countries of Asia, including Malaysia, have in recent years experienced spectacular economic growth and social change. This, together with declining fertility rates and mortality rates, and accompanying increased expectation of life at birth have resulted in rapid population ageing of these countries. However, relative to the developed countries, where fertility and mortality declines, ...

1% in 2000. Although the objective was far from being reached (the current rate being close to 2%), in 2000 Mexico had 53 million inhabitants fewer than it would have had if fertility had remained at its 1970 level. The population pyramids of 1930, 1970 and 2000 clearly illustrate this dynamics (Figure 2). In 1930 the population was beginning to recover from the aftereffects of the Revolution a...

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...

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...

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...

AIM Skin burn is a health problem that requires fast and accurate treatment. If not well-treated, the burn will cause various damaging conditions for the patient. The leaf extract of Madeira vine (Anredera cordifolia (Ten.) Steenis), or popularly known as Binahong in Indonesia, has been used to treat various diseases. The purpose of this research is to determine the effects of leaf extracts of ...

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 ...

There are 43 clones of Pinot Noir currently published by the National Technical Institution for Viticultural Improvement in France (ENTAV) and over 75 selections from Foundation Plant Services (FPS) at UC Davis. Viticulturists speculate that there are anywhere from 200 – 1,000 genetic variants that may exist for any given grape variety. An important part of vineyard management is crop estimatio...
