Tail Dependence of the Gaussian Copula Revisited [PDF]
SSRN Electronic Journal, 2016 Tail dependence refers to clustering of extreme events. In the context of financial risk management, the clustering of high-severity risks has a devastating effect on the well-being of firms and is thus of pivotal importance in risk analysis.When it comes to quantifying the extent of tail dependence, it is generally agreed that measures of tail ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Animal‐assisted activities (AAAs) with therapy dogs have shown positive effects on patient well‐being and quality of life in various areas of medicine, including pediatric oncology. However, research on this topic is limited. The aim of this study is to present the current status of AAA in pediatric oncology in Germany, Austria, and

Tail dependence of bivariate skew normal triangular array with varying correlation coefficients
Statistical Theory and Related FieldsThe tail dependence coefficient measures extremal dependence between two random variables. In this note, we investigate the tail dependence of a bivariate skew normal triangular array with equal skewness and varying correlation coefficients [Formula: see

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

The Tale of Tail Dependence: Modeling height–diameter relationships with elliptical copulas
Forest EcosystemsModeling height–diameter (H–D) relationships is fundamental to forest management. Copula could be used to simulate H–D distributions that mirror the underlying dependence structures of an observed relationship.

Power-Law Distributions from Sigma-Pi Structure of Sums of Random Multiplicative Processes
Entropy, 2017 We introduce a simple growth model in which the sizes of entities evolve as multiplicative random processes that start at different times. A novel aspect we examine is the dependence among entities.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
