IET Generation, Transmission & Distribution, 2020 This work focuses on calculating the amount of control reserve, which can be provided by a pool of renewable power plants on the next day. The power forecast of wind and solar power plants depends on the weather forecast, which always contains errors.

Risk return of forward contracting corn with crop insurance
Journal of the Agricultural and Applied Economics Association, EarlyView.Abstract Forward contracting is a common pre‐harvest marketing strategy for row crops, with evidence suggesting higher prices during summer months due to embedded weather risk premiums. While aggressive forward contracting increases farmers' yield risk and potential non‐delivery penalties, crop revenue protection can help offset these financial burdens.

WORLD FINANCIAL RELATIONS: UNDERSTANDING THE CREDIT DERIVATIVE SWAPS (CDS) DEPENDENCE STRUCTURE
REAdThis study investigates the copula model that best fit to model the dependence structure of Credit Derivative Swaps (CDS) spreads. For the analysis, we consider daily data from the period of January 1, 2009 to December 31, 2014.

Truncation Mixture R-Vine Copulas
, 2021 Uncovering hidden mixture correlation among variables have been investigating in the literature using mixture R-vine copula models. These models are hierarchical in nature. They provides a huge flexibility for modelling multivariate data. As the dimensions increases, the number of the model parameters that need to be estimated is increased dramatically,

Bivariate postprocessing of wind vectors
Quarterly 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

Explaining predictive models using Shapley values and non-parametric vine copulas
Dependence Modeling, 2021 In this paper the goal is to explain predictions from complex machine learning models. One method that has become very popular during the last few years is Shapley values.

Journal 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’.

Molecular 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.
