Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Small-Signal Modelling and Analysis of Doubly-Fed Induction Generators in Wind Power Applications [PDF]
The worldwide demand for more diverse and greener energy supply has had a significant impact on the development of wind energy in the last decades. From 2 GW in 1990, the global installed capacity has now reached about 100 GW and is estimated to grow ...

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 ...

Abstract Online technologies are required for accessing essential services, such as healthcare, transportation, and education. Challenges to online technology access can prevent resource‐constrained communities from connecting to these services. Human intermediaries who act in the middle space between technology and the person using the technology may ...

Abstract Valuing parental engagement, as part of home–school collaboration, can benefit children's learning. This article focuses on parents and school‐based staff's (N = 120) experiences of children's learning occurring at home during the COVID‐19 lockdowns (2020–2021), both school‐mandated and other learning activities.
