The Enigma of the Sphinx
This paper presents an evaluation of the benefits and user acceptance of a multimodal interface in which the user interacts with a game-like interactive virtual reality application “The Enigma of the Sphinx”. The interface consists of a large projection screen as the main display, a “magic wand”, a stereo sound system and the user‘s voice for “casting spells”. We present our conclusions concern...
متن کاملThe Piancatelli rearrangement: new applications for an intriguing reaction.
Nearly forty years ago, at the University of Rome, Giovanni Piancatelli and co-workers discovered the acid-catalyzed water-mediated rearrangement of 2-furylcarbinols into 4-hydroxycyclopentenones. These motifs are core components of several pharmacologically active compounds and precursors of many natural products. The main features of this reaction are the simple experimental conditions, the s...
متن کاملUnusual rearrangement of 3-hydrazino-rifamycins leading to the enlargement of the "natural" ansa bridge.
Sir: As part of our effort aimed at the synthesis of new rifamycin derivatives,1) the 3-hydrazino derivatives of rifamycin S (2) and SV (3) have been obtained by treating 3-bromorifamycin S (1a) with isopropylidene-methyl hydrazine and with isopropylidene-methyl hydrazine followed by hydrazine, respectively.2) We wish to describe here a novel rearrangement of the ansa bridge under acidic condit...
متن کاملSYNTHESIS AND THERMAL REARRANGEMENT OF OXYGEN HETEROCYCLIC SPIRANS
Thermal rearrangement of spirans (14) and (31) yields the xanthones (16,34) and diphenylrnethane (15, 32), respectively. The structure for xanthone (16), isolated from thermolysis, has been established by reduction to xanthene (20) followed by reoxidation to give xanthone (16). Alternatively, methylation of the diphenylmethane (15) followed by heating with selenium dioxide also yields xant...
متن کاملModels for antigen receptor gene rearrangement. II. Multiple rearrangement in the TCR: allelic exclusion or inclusion?
This series of papers addresses the effects of continuous Ag receptor gene rearrangement in lymphocytes on allelic exclusion. The previous paper discussed light chain gene rearrangement and receptor editing in B cells, and showed that these processes are ordered on three different levels. This order, combined with the constraints imposed by a strong negative selection, was shown to lead to effe...
