Serum bile acids as a prognostic biomarker in biliary atresia following Kasai portoenterostomy
Serum bile acid levels predict outcomes in patients with biliary atresia who achieve normalized bilirubin levels after Kasai portoenterostomy. Abstract Background and Aims In biliary atresia, serum bilirubin is commonly used to predict outcomes after Kasai portoenterostomy (KP).

Abstract Hepatocellular adenomas (HCAs) are benign liver tumors associated with bleeding or malignant transformation. Data on the indication for surgery are scarce. We analyzed indications and outcome of patients operated for HCAs < 50 mm compared to HCAs ≥ 50 mm. Changes in final postoperative diagnosis were assessed.

Defossilisation of the Energy Supply of a Chemical Site by Integration of a Carnot Battery
This study presents the results of a techno‐economic analysis of CO2‐free energy supply concepts for electricity and heat for the defossilisation of a chemical park in Germany for the model years 2030 and 2045. The focus is on the integration of a Carnot battery with thermal energy storage, which enables the flexible use of green fuels and renewable ...

Checking the definiteness of forms
It is suggested to verify the positive definiteness (or semidefiniteness) of finite quadratic and fourth-degree forms on the basis of the classical unconstrained optimization techniques, such as the steepest descent method and the conjugate gradient ...

Predicting cervical cancer DNA methylation from genetic data using multivariate CMMP
Abstract Epigenetic modifications link the environment to gene expression and play a crucial role in tumour development. DNA methylation, in particular, is gaining attention in cancer research, including cervical cancer, the focus of this study.

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions
Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

A partial envelope approach for modelling multivariate spatial‐temporal data
Abstract In the new era of big data, modelling multivariate spatial‐temporal data is a challenging task due to both the high dimensionality of the features and complex associations among the responses across different locations and time points.
