Foundations of Ghost Stability
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.

YOLO‐Behaviour: A simple, flexible framework to automatically quantify animal behaviours from videos
Methods in Ecology and Evolution, Volume 16, Issue 4, Page 760-774, April 2025.Abstract Manually coding behaviours from videos is essential to study animal behaviour but it is labour‐intensive and susceptible to inter‐rater bias and reliability issues. Recent developments of computer vision tools enable the automatic quantification of behaviours, supplementing or even replacing manual annotation.

Essentially tight bounds for rainbow cycles in proper edge‐colourings
Proceedings of the London Mathematical Society, Volume 130, Issue 4, April 2025.Abstract An edge‐coloured graph is said to be rainbow if no colour appears more than once. Extremal problems involving rainbow objects have been a focus of much research over the last decade as they capture the essence of a number of interesting problems in a variety of areas.

Journal of Computational Chemistry, Volume 46, Issue 8, 30 March 2025.The electrons of the overlapping, basically neutral fragments do not cause electrostatic repulsion but attraction by the pulling nuclei. The Pauli‐repulsive quantum kinetic increase of the energy density in the overlapping region always leads to reactions of the geometric structure and the electronic wave function. According to the virial theorem, this
