T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

The Anatomical Record, EarlyView.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Hierarchical control-based fault ride-through of VSC-HVDC considering impacts of renewable energy

International Journal of Electrical Power & Energy Systems
When a short-circuit fault occurs at the receiving-end grid, the unbalanced power in voltage source converter based high voltage direct current (VSC-HVDC) should be consumed to prevent excessive DC voltage rise, thereby enabling fault ride-through ...

Developmental differences in cortical bone structure in chimpanzee and human femora reflect early locomotor independence in humans

The Anatomical Record, EarlyView.
Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

Study on fault ride-through control of islanded wind farm connected to VSC-HVDC grid based on the VSC converter AC-side bus forced short circuit

The Journal of Engineering, 2019
Wind farms integrated to an AC power system through a voltage source converter-based high-voltage direct current system (VSC-HVDC) are viewed as islanded wind farms. The wind farm side converter of VSC-HVDC maintains a constant frequency of the wind farm

Rimplasty: An Arthroscopic Technique for Patients With Isolated Patellar Chondromalacia Based on Autologous Matrix‐induced Chondrogenesis+ and Limited Trochleoplasty

Arthroscopy Techniques, EarlyView.
Abstract Anterior knee pain is a common problem that can be difficult to treat. One potential cause of these symptoms is supratrochlear rim, which has been linked to isolated patellar chondromalacia in patients with patella alta and without any history of patellar dislocation or subluxation.

The quality of interaction with children in collective play: Children's agency

British Educational Research Journal, EarlyView.
Abstract There is a growing body of studies on increasing the quality of infant–toddler education and care. Yet little attention has been directed towards how to bring toddlers' agency and perspective to their personally meaningful learning in collective play.

Activism as education in and through the youth climate justice movement

British Educational Research Journal, EarlyView.
Abstract Young people worldwide are increasingly participating in a global movement for climate justice, yet to date, little research has examined how youth climate justice activists conceive of and experience activism as education. The present study used in‐depth, semi‐structured interviews with 16 US climate justice activists (aged 15–17) to address ...
