UNLABELLED During submaximal cycling, the neuromuscular system has the freedom to select different intermuscular coordination strategies. From both a basic science and an applied perspective, it is important to understand how the central nervous system adjusts pedaling mechanics in response to changes in pedaling conditions. PURPOSE To determine the effect of changes in pedal speed (a marker ...

AIMS There is increasing awareness of the needs of children with low vision, particularly in developing countries where programmes of integrated education are being developed. However, appropriate low vision services are usually not available or affordable. The aims of this study were, firstly, to assess the need for spectacles and optical low vision devices in students with low vision in schoo...

Advances in neural imaging technologies, such as functional magnetic resonance imaging (fMRI), have made it possible to obtain images of human brain activity during motor tasks. However, technical challenges have made it difficult to image the brain during multijoint lower limb movements like those involved in locomotion. We developed an MR compatible pedaling device and recorded human brain ac...

The geometric small property (Borho-MacPherson [BM]) of projective morphisms implies a description of their singularities in terms of intersection homology. In this paper we solve the smallness problem raised by Nakajima [N8, N6] for certain resolutions of quiver varieties [N8] (analogs of the Springer resolution) : for Kirillov-Reshetikhin modules of simply-laced quantum affine algebras, we ch...

This letter reports basic acoustic phenomena related to part-pedaling in the piano. With part-pedaling, the piano tone can be divided into three distinct time intervals: initial free vibration, damper-string interaction, and final free vibration. Varying the distance of the damper from the string, the acoustic signal and the damper acceleration were measured for several piano tones. During the ...

Arabidopsis thaliana KORRIGAN1 (KOR1) is an integral membrane endo-β1,4-glucanase in the trans-Golgi network and plasma membrane that is essential for cellulose biosynthesis. The extracellular domain of KOR1 contains eight N-glycosylation sites, N1 to N8, of which only N3 to N7 are highly conserved. Genetic evidence indicated that cellular defects in attachment and maturation of these N-glycans...

recently multiple studies have shown that elevated homocysteine levels may be associated with ophthalmic vascular disease. to investigate the role of high plasma levels of homocysteine in the patients with retinal vein occlusion, 21 patients with retinal vein occlusion (rvo) and 20 age and sex matched controls without rvo were included in this retrospective case–control study. information regar...

Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...
