N THE OTHER ARTICLES in this series the digital computer has been thought of as a purely menial tool—in fact, as a kind of intellectual spade. This, it has been shown, can indeed assist a human scholar who is working on language, by performing for him a series of irksome repetitive tasks: tasks such as counting the number of words in a text, making a concordance of their occurrence, and mechani...

This paper summarizes the major conclusions of twenty years of research in robot force control, points out remaining problems, and introduces issues that need more attention. By looking at force control from a distance, a lot of common features among diierent control approaches are revealed; this allows us to put force control into a broader (e.g., diierential-geometric) context. The paper star...

the eyes are organs that detect light and convert it into electro-chemical impulses in neurons. visual perception is the ability to interpret information and surroundings from the effects of visible light reaching the eye. medicine recognizes that altitudes above 1500 meters start to affect humans so that, the eye is very sensitive to restriction of its supply of oxygen. a dimming of vision acc...

Neuronal responses that were observed during smooth-pursuit eye movements were recorded from cells in rostral portions of the nucleus reticularis tegmenti pontis (rNRTP). The responses were categorized as smooth-pursuit eye velocity (78%) or eye acceleration (22%). A separate population of rNRTP cells encoded static eye position. The sensitivity to pursuit eye velocity averaged 0.81 spikes/s pe...

Dear editor Periodical assessment and monitoring of journal statistics by editor in chief and other related editorial board  bring important insight to determine the quality of scientific production process and provide detail if a journal is paving the way to  join the mainstream internationally recognized indexing databases such as ISI [www.webofknowledge.com], Medline [www.Pubmed.org] and Sc...

Objective(s): In this study, a stable bear bile-loaded pH sensitive in-situ eye drop gel was prepared for sustain delivery and enhanced therapeutic application. Materials and Methods: Bear bile-loaded in-situ ocular gels with different Carbopol/Hydroxypropyl methylcellulose (HPMC)  ratios were prepared and their stability was tested in P...
