This prospective study examined the effects of prismatic adaptation on visual exploration strategies in patients with left unilateral spatial neglect (USN). Photo-oculographic gaze recordings were obtained, as the subjects (28 brain-damaged; 15 control) performed a free visual exploration task before and after a session of prismatic adaptation. (i) Before prismatic adaptation, the pattern of vi...

The temperature dependence of fatigue crack growth in stage IIb was investigated Ti–0.49 mass%O with an alpha single phase. It found that the rate independent at temperatures above 300 K. EBSD maps beside showed prismatic slips 〈a〉 dislocations were dominantly activated during growth. reason why is discussed numerical crystal plasticity analysis. shown local strain notch tip higher than macrosc...

With the help of the research results presented here and on the basis of a graphic analysis we aim to prove the existence of a relationship between the difference in prismatic refractive power and the thickness, curvature radius, and type of material used for panoramic oculars in protective spectacles, goggles, and face shields. The difference in the prismatic refractive power is a fundamental ...

Prismatic adaptation has been shown to induce a realignment of visuoproprioceptive representations and to involve parietocerebellar networks. We have investigated in humans how far other types of functions known to involve the parietal cortex are influenced by a brief exposure to prismatic adaptation. Normal subjects underwent an fMRI evaluation before and after a brief session of prismatic ada...

The authors show that prismatic adaptation can reduce tactile inattention in stroke patients with unilateral neglect. Four patients with visuospatial neglect and tactile extinction underwent 10-minute application of 20 degrees right-shifting prismatic lenses during pointing. This improved contralesional tactile perception in all patients, even for a task requiring no exploration or spatial moto...

This paper presents a simple and efficient method to determine the self-equilibrated configurations of prismatic tensegrity structures with dihedral symmetry. It is demonstrated that stability of prismatic tensegrity structures is not only determined by the connectivity manner of the members, but also sensitive to the height/radius ratio and the stiffnss/prestress ratio. A catalogue of symmetri...
