In this paper, a novel observer-based robust preview tracking controller design method is proposed for a class of continuous-time Lipschitz nonlinear systems with external disturbances and unknown states.First, a state observer is designed to reconstruct unknown system states.Second, using differentiation, the state lifting technique, the different
Perinatal hypoxia-ischemia represents a significant risk to CNS development, leading to high mortality rates, diverse damages, and persistent neurological deficits.Despite advances in neonatal medicine in recent decades, the incidence of HIE remains substantial.Motor deficits can manifest early, while cognitive impairments may be diagnosed later, e
Abstract Binocular rivalry (BR) is a visual perception phenomenon that occurs when each eye perceives different images and stimuli, causing alternating monocular dominance.To measure BR, many studies have used two monocular conflicting images to induce monocular alternations.Here we chose a group of participants with oblique astigmatism (OA) and wh
Background: Understanding the characteristics of oculocutaneous albinism (OCA) in African populations is crucial for developing appropriate support strategies.Aim: This study aims to comprehensively analyse the demographic and visual characteristics of individuals with OCA in Botswana, Africa.Setting: This retrospective study was conducted at a pri
