Expert Systems, Volume 43, Issue 8, August 2026.ABSTRACT Improving classification performance on imbalanced datasets remains a challenging problem in machine learning. Synthetic oversampling techniques such as SMOTE are widely used to address class imbalance; however, their random interpolation strategy often ignores structural data properties, which may affect classifier generalisation.

Genetic Composition Is Unrelated to Song Content in a Wild Passerine
Molecular Ecology, Volume 35, Issue 15, August 2026.ABSTRACT Birdsong is a key sexual signal that varies substantially among individuals and populations. Understanding whether song similarity reflects genetic similarity is central for evaluating its role in sexual selection, population divergence and evolutionary dynamics, although partial vocal learning can obscure this relationship in many species ...

Power Through Visibility: How Policy Narratives Matter in Climate Change Debate on X
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Research on policy narratives has shown that political actors employ certain narrative strategies in their competition for attention. Although we know that actors' narrative strategies coincide with existing power constellations (e.g., government vs. opposition), the ways in which they influence public attention remain largely unknown. In this

High Relative Accuracy Computations With Covariance Matrices of Order Statistics
Mathematical Methods in the Applied Sciences, Volume 49, Issue 11, Page 11794-11810, 30 July 2026.ABSTRACT In many statistical applications, numerical computations with covariance matrices need to be performed. The error made when performing such numerical computations increases with the condition number of the covariance matrix, which is related to the number of variables and the strength of the correlation between the variables. In a recent work,
