PIII and derived PII analysis in a patient with retinal dysfunction with supernormal scotopic ERG Subtitle: Retinal dysfunction with supernormal scotopic ERG
Purpose: To present electroretinographic (ERG) findings in a patient with retinal dysfunction with supernormal scotopic ERG, and to analyze rod and cone PIII components and rod inner nuclear layer (derived PII) responses. Patient: A Japanese 11-year-old girl complained of poor visual acuity. There was no parental consanguinity in her family. The corrected visual acuity was 0.7 in both eyes. No ...
متن کاملHow social distance shapes human-robot interaction
This paper investigates how social distance can serve as a lens through which we can understand human–robot relationships and develop guidelines for robot design. In two studies, we examine the effects of distance based on physical proximity (proxemic distance), organizational status (power distance), and task structure (task distance) on people's experiences with and perceptions of a humanlike...

Human scotopic sensitivity is regulated postreceptorally by changing the speed of the scotopic response.
Sensitivity regulation enables the visual system to function effectively from the absorption of a few photons at the lowest visual threshold to the absorption of enough photons to bleach nearly all the light-sensitive photopigment in the eye. Here, we investigate sensitivity regulation in the rod (or scotopic) range from -3.8 to -0.8 log(10) scotopic trolands. Over most of this range, the rate ...
متن کاملPedagogical Principles of the Theories of Interaction in Distance Learning: The Study of Interaction Anderson Model in Web-based Environments
Background: Interaction is considered a necessary, and integral part in all forms of distance learning and web -based learning environments. That how much technologies can support and help interactions is one of the most important issues that should be considered in the web-based environment. These interactions seek to engage students with other students, teachers and also non-human contex...
