Imbalance‐Aware Credit Card Fraud Detection Using Multi‐Autoencoders and Generative Ensemble Learning

Expert Systems, Volume 43, Issue 5, May 2026.
ABSTRACT Credit card fraud detection remains a challenging research problem due to the class imbalance issue caused by the rarity of fraudulent transactions. Classical oversampling techniques such as SMOTE, ADASYN and their variants help balance data but do not reflect the nonlinear structure of real‐world fraud, leading to poor generalization.

Nonparametric inference for second order stochastic dominance [PDF]

This paper deals with nonparametric inference for second order stochastic dominance of two random variables. If their distribution functions are unknown they have to be inferred from observed realizations. Thus, any results on stochastic dominance are in

Individual differences in effects of stressful life events on childhood ADHD: genetic, neural, and familial contributions

Journal of Child Psychology and Psychiatry, Volume 67, Issue 5, Page 788-800, May 2026.
Background This study elucidates the intricate relationship between stressful life events and the development of ADHD symptoms in children, acknowledging the considerable variability in individual responses. By examining these differences, we aim to uncover the unique combinations of factors contributing to varying levels of vulnerability and ...

A Predictive Model for Intrapartum Cesarean Delivery in Multiparous Women After Active Labor Onset

Journal of Obstetrics and Gynaecology Research, Volume 52, Issue 5, May 2026.
ABSTRACT Objective Although prediction models for cesarean delivery have been established for nulliparous women, few have been developed for multiparous women, particularly for predicting intrapartum cesarean delivery after the onset of active labor. This study aimed to develop and validate a risk prediction model for intrapartum cesarean delivery in ...

Gradual Changes in Functional Time Series

Journal of Time Series Analysis, Volume 47, Issue 3, Page 632-650, May 2026.
ABSTRACT We consider the problem of detecting gradual changes in the sequence of mean functions from a not necessarily stationary functional time series. Our approach is based on the maximum deviation (calculated over a given time interval) between a benchmark function and the mean functions at different time points.

Proteomic Trajectories of Metabolic and Proteostatic Adaptation During Normothermic Liver Perfusion

Liver International, Volume 46, Issue 5, May 2026.
ABSTRACT Background Normothermic machine perfusion (NMP) enables metabolic restoration and viability testing of liver grafts, but current viability criteria incompletely predict post‐transplant outcomes. The molecular basis of graft resilience or biliary vulnerability remains unclear. This study aimed to characterise tissue‐level proteomic trajectories

“Taking What's Ours”: Restrictionist Attitudes Toward Immigration and Threat to Sense of Group Position in the United States

Sociological Inquiry, Volume 96, Issue 2, Page 264-284, May 2026.
Calls to limit immigration are fueled by the belief immigration threatens individual and collective welfare, yet studies on support for restrictionism remain equivocal on this relationship. We explore this relationship and contribute to existing research by measuring group threat as a latent construct based on Blumer's (1958:3) definition of it as an ...

Uncertainty Calibration in Molecular Machine Learning: Comparing Evidential and Ensemble Approaches

Chemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.
Raw uncertainty estimates from deep evidential regression and deep ensembles are systematically miscalibrated. Post hoc calibration aligns predicted uncertainty with true errors, improving reliability and enabling efficient active learning and reducing computational cost while preserving predictive accuracy.

Interpretable LightGBM model with SHAP analysis predicts non‐excellent response to initial radioiodine therapy in differentiated thyroid carcinoma

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Purpose To identify independent determinants influencing therapeutic outcomes of initial radioactive iodine (131I) therapy in differentiated thyroid carcinoma (DTC) and establish an interpretable predictive framework for clinical decision‐making.
