Cytomegalovirus (CMV) shares many properties with other members of the herpesvirus family it exhibits latency, reactivates under suitable conditions to cause human disease, and it is incurable. CMV is the primary opportunistic viral infection in the immunosuppressed person and gives rise to a wide spectrum of disease. CMV is a major cause ofmorbidity and mortality among patients with AIDS, and ...

OBJECTIVES The aim of this study was to identify the causes of visual impairment in children attending schools for students with visual impairment and to identify children suitable for treatment and rehabilitation. MATERIALS AND METHODS All students were examined in our department by a pediatric ophthalmologist and an ophthalmologist experienced in low vision and visual rehabilitation. The ch...

A limited number of research developments in the field of speech enhancement have been implemented into commercially available hearing-aids. However, even sophisticated aids remain ineffective in environments where there is overwhelming noise present. Human performance in such situations is known to be dependent upon input from both the aural and visual senses that are then combined by sophisti...

We investigated whether the statistical predictability of a target's location would influence how quickly and accurately it was classified. Recent results have suggested that spatial probability can be a cue for the allocation of attention in visual search. One explanation for probability cuing is spatial repetition priming. In our two experiments we used probability distributions that were con...

Future Lunar missions will require significant and speedy traverses of the terrain by robotic vehicles. Because of the Moon’s proximity to the Earth it is very tempting to tele-operate robotic vehicles from the Earth, rather than have them operate autonomously. We have found that operators quickly develop the ability to predict the effect of their commands but have difficulty synchronizing thei...
