In our everyday presentations of an immersive projection technology (IPT) system we have noted some problems and issues that can detract from the overall experience. In this paper we take the view that in order to make a successful demonstration of an IPT system, it is important to consider the complete experience, from preparation to enter, to retirement from the place of the demonstration. Th...

Abstract Following Santaló’s approach, we prove several characterizations of a disc among bodies constant width, projection lengths, or section lengths on given families geodesics.

Feedback plays important roles in sensory processing. Mushroom bodies are believed to be involved in olfactory learning/memory and multisensory integration in insects. Previous cobalt-labeling studies have suggested the existence of feedback from the mushroom bodies to the antennal lobes in the honey bee. In this study, the existence of functional feedback from Drosophila mushroom bodies to the...

Microelectrodes were passed through the dorsal hippocampal formation of unrestrained rats, recording for at least 5 min each 35.3 pm. At each site the amplitude and duration of action potential spikes, frequency of firing, relation to slow wave theta rhythm, and presence of complex spikes or theta cells was recorded. One thousand and fourteen neurons were recorded from. (When recording from man...

We disprove a conjecture of A. Koldobsky asking whether it is enough to compare (n−2)-derivatives of the projection functions of two symmetric convex bodies in the Shephard problem in order to get a positive answer in all dimensions.
