Head and neck cancer: a comprehensive review of epidemiology, global burden and advances in radiotherapy

Karunya A S, K. Sudeep Kumara, Avin Kumar, Kamalaksh Shenoy

Abstract Head and neck cancer (HNC), a heterogeneous group of malignancies that arising from the mucosal surfaces of the Upper Aerodigestive Tract (UADT), is a major health concern worldwide. By 2050, the number of cancer cases worldwide is expected to reach 35 million, with nearly half of all new cases and deaths occurring in Asia. In India, HNC is particularly prevalent accou…

Perceived Training Utility of Artificial Intelligence in Virtual Reality Taekwondo Sparring: A Repeated-Measures Study

Hyo Taek Lee Boseob Heo

Virtual reality (VR) can provide repeatable sport-specific practice, but the training value athletes assign to AI-controlled opponents remains uncertain. This study compared perceived training utility between AI-controlled and human-controlled VR Taekwondo sparring and examined whether bout duration modified this response. Thirty-one collegiate Taekwondo athletes completed four…

Co-Reflection Versus Self-Reflection in Graphic Organizer-Facilitated Training in the Metaverse: Evidence From Students’ Knowledge Gains, Perceptions, and Case-Handling Performances

Gwo‐Jen Hwang, Chun‐Chun Chang

In vocational education and training, developing students’ communication, teamwork, reflection, and problem-solving skills has become increasingly important. Previous studies have integrated practical cases into metaverse-based courses using the Problem-Guiding, Exploration, and Reflection (PER) process supported by graphic organizers; however, students’ critical thinking depth…

Visuomotor mismatch EEG responses over occipital cortex of freely moving human subjects

Magdalena Sołyga, Marek Żelechowski, Georg B. Keller

Likely the strongest predictor of visual feedback is self-motion. In mice, the coupling between movement and visual feedback is learned with first visual experience of the world, and brief perturbations of the coupling result in strong visuomotor mismatch responses in visual cortex that possibly reflect prediction errors. In humans, predictive coding has primarily been studied …
