The author studied anatomical variations of the origin of the chorda tympani nerve from the mastoid portion of the facial nerve. The studies were performed on 200 specimens of human temporal bone. It was found that the chorda tympani may arise from the facial nerve in three levels: most commonly from the mid third of its mastoid segment (70%), less commonly from the proximal third (20%), an...

• In the current study we have applied the concept of presence to 3DTV research. More specifically, we took this concept to reflect the increased perceptual linkage between the observer and the mediated environment, supporting an illusion of non-mediation. We applied the continuous assessment methodology to reveal time-variant properties of presence, which were hitherto largely ignored, and to ...

We measure variations in orientation of fourteen dynamic fibrils as a function of time in a small isolated plage and nearby network using a 10-min time sequence of Hα filtergrams obtained by the Dutch Open Telescope. We found motions with average angular velocities of the order of 1 deg min −1 suggesting systematic turning from one limit position to another, particularly apparent in the case of...
