Ripple Effects: Social Turmoil Following Infant Kidnapping Attempts in Wild Geladas

Ethology, Volume 132, Issue 7, Page 485-497, July 2026.
Graphical abstract illustrating the social consequences of infant kidnapping in wild geladas (Theropithecus gelada). The study monitors a 28‐day period divided into a 14‐day pre‐kidnapping phase and a 14‐day post‐kidnapping phase. ABSTRACT Infant kidnapping is an extreme social disruption reported in some primate species, yet its consequences on social

Predictive Control Algorithm Technique for Multilevel Asymmetric Cascaded H-Bridge Inverters

IEEE Transactions on Industrial Electronics, 2008
Predictive control algorithms have been proposed for power electronic converters, featuring a high performance in terms of dynamic behavior. This is true due mainly to the accurate modeling and the finite set of inputs or possible switching combinations. However, when it is used in multilevel converters, the dynamic performance is degraded, because the
