Wind–Storage Coordinated Control Strategy for Suppressing Repeated Voltage Ride-Through of Units Under Extreme Weather Conditions

Energies
In practical engineering, large-scale wind power integration typically requires long-distance transmission lines to deliver power to load centers. The resulting weak sending-end systems lack support from synchronous power sources.

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 ...

Fault Ride-Through Control Strategy for Variable Speed Pumped Storage Unit with Full-Size Converter

Applied Sciences
Fault ride-through is a prerequisite for ensuring continuous operation of a variable-speed pumped storage unit with a full-size converter (FSC-VSPU) and providing support for the renewable energy and power grid.

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 ...

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.

Anatomic All‐Inside Repair of the Anteroinferior and Posterosuperior Popliteomeniscal Fascicles for Hypermobile Lateral Meniscus

Arthroscopy Techniques, EarlyView.
Abstract Hypermobile lateral meniscus refers to abnormal mobility of an otherwise morphologically normal meniscus without obvious tears, causing lateral knee pain due to catching or locking of the lateral meniscus during flexion. The most common cause is rupture or elongation of the popliteomeniscal fascicles (PMFs), which connect the lateral meniscus ...

Biographies, ontological security and the socio‐spatial politics shaping teachers' mobility in remote Australia

British Educational Research Journal, EarlyView.
Abstract The global teacher shortage continues to intensify, with disparate impacts across geographic and socio‐economic communities. In Queensland, Australia, where this study originates, post‐COVID teacher shortages have intensified workforce pressures, leaving several regional, rural and remote schools as some of the ‘hardest‐to‐staff’ in the ...
