Bivariate postprocessing of wind vectors

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We introduce three novel bivariate postprocessing approaches and analyze their performance for joint postprocessing of bivariate wind‐vector components in Germany. Bivariate vine‐copula‐based models, a bivariate gradient‐boosted version of ensemble model output statistics (EMOS), and a bivariate distributional regression network (DRN) are compared with

Development of decomposition-based model using Copula-GARCH approach to simulate instantaneous peak discharge

open access: yesApplied Water Science, 2023
Estimation of instantaneous peak discharge is important in the design of hydraulic structures and reservoir management. In this study, a new approach called CEEMD-Copula-GARCH is presented for simulating instantaneous peak discharge in the Qale Shahrokh ...

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

open access: yesJournal of Sociolinguistics, EarlyView.
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’.

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.

Copulas for Covariate Simulation in Pharmacometrics

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 4, April 2026.
ABSTRACT Patient‐specific covariates are commonly incorporated in pharmacometric and quantitative system pharmacology models to predict differences in pharmacokinetic or pharmacodynamic profiles between patients. When simulating new virtual populations of patients, generating realistic covariate sets that accurately reflect the correlation structures ...

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 ...

Alternative Approaches for Estimating Highest‐Density Regions

open access: yesInternational Statistical Review, Volume 94, Issue 1, Page 97-120, April 2026.
Summary Among the variety of statistical intervals, highest‐density regions (HDRs) stand out for their ability to effectively summarise a distribution or sample, unveiling its distinctive and salient features. An HDR represents the minimum size set that satisfies a certain probability coverage, and current methods for their computation require ...

Uncertainty Quantification in Planning Aircraft Ground Movement Operations With Towbarless Robotic Tractors

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 5, Page 2542-2556, 25 March 2026.
ABSTRACT This article addresses the problem of quantifying the uncertainty in planning aircraft ground movement operations using towbarless robotic tractors taking into account the inherent uncertainties of the problem, specifically, the uncertainties in the weight of the aircraft and in the rolling resistance of the wheels of the main landing gear ...
