‘Gen Z Language? Y'all Mean AAVE’: The Appropriation of African American Vernacular English as ‘TikTok Language’

open access: yesJournal of Sociolinguistics, Volume 30, Issue 3, Page 255-267, June 2026.
ABSTRACT Sociolinguistic research has long documented the appropriation of African American Vernacular English (AAVE) across media including film, music and advertising. In this article, we add to this body of work by exploring the digital recontextualisation of a subset of AAVE features as ‘TikTok/internet language’.

Model distances for vine copulas in high dimensions [PDF]

open access: yesStatistics and Computing, 2017
Vine copulas are a flexible class of dependence models consisting of bivariate building blocks and have proven to be particularly useful in high dimensions. Classical model distance measures require multivariate integration and thus suffer from the curse of dimensionality.

Joint Probability Distribution of Wind–Wave Actions Based on Vine Copula Function

open access: yesJournal of Marine Science and Engineering
During its service life, a deep-sea floating structure is likely to encounter extreme marine disasters. The combined action of wind and wave loads poses a threat to its structural safety.

Water‐Regulated Carbon Cost–Benefit Drives Divergent Effective Rooting Depth Across the Greening Loess Plateau

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Large‐scale vegetation restoration is reshaping belowground systems globally, yet root dynamics remain poorly quantified, limiting predictions of ecosystem resilience to hydroclimatic variability. Rooting depth reflects a trade‐off between carbon benefits and respiratory costs, but assessment is hampered by soil‐moisture uncertainty and weak ...

Sex‐Specific Gene Expression Ontogeny During Gonadal Development in Post‐Metamorphic Xenopus tropicalis

open access: yesMolecular Reproduction and Development, Volume 93, Issue 4, April 2026.
Post‐metamorphic gonadal development in Xenopus tropicalis was analyzed through integrated morphometric, histological, and transcriptional approaches. Males showed upregulation of cyp17, amh, and amhr2, whereas females exhibited an increased aldh1a2 and ddx4.

Assessing Efficiency of D-Vine Copula ARMA-GARCH Method in Value at Risk Forecasting: Evidence from PSE Listed Companies

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2015
The article points out the possibilities of using static D-Vine copula ARMA-GARCH model for estimation of 1 day ahead market Value at Risk. For the illustration we use data of the four companies listed on Prague Stock Exchange in range from 2010 to 2014.

Patient‐reported outcomes, postoperative pain and pain relief after day‐case surgery (POPPY): chronic post‐surgical pain prevalence and associations*

open access: yesAnaesthesia, Volume 81, Issue 4, Page 489-499, April 2026.
Summary Introduction Day‐case surgical activity is increasing in the UK yet there is a lack of data on the prevalence of chronic post‐surgical pain in this population. This study uses data from the POPPY study to estimate the prevalence of chronic post‐surgical pain after day‐case surgery, its relationship with quality of life and also explores ...

Stepwise Variational Inference with Vine Copulas

open access: yesCoRR
We propose stepwise variational inference (VI) with vine copulas: a universal VI procedure that combines vine copulas with a novel stepwise estimation procedure of the variational parameters. Vine copulas consist of a nested sequence of trees built from copulas, where more complex latent dependence can be modeled with increasing number of trees.

Approximate Uncertainty Modeling in Risk Analysis with Vine Copulas [PDF]

open access: yesRisk Analysis, 2015
Many applications of risk analysis require us to jointly model multiple uncertain quantities. Bayesian networks and copulas are two common approaches to modeling joint uncertainties with probability distributions. This article focuses on new methodologies for copulas by developing work of Cooke, Bedford, Kurowica, and others on vines as a way of ...
