Realizing doubles: a conjugation zoo

A Ubiquitous Zoo Guide

In this paper a novel visitor information system for zoos is described. Vistors going through the zoo hold PDAs close to RFID tags, which are attached to animal cages, and which thus identify the animals. Over WLAN, the PDAs send this ID to a Web server, which sends back a multimedia Web presentation for the respective animal. The novel idea is to additionally attach the Web server to a global ...

Quantization of Drinfel’d doubles

Hopf algebra quantizations of 4-dimensional and 6-dimensional real classical Drinfel’d doubles are studied by following a direct “analytic” approach. The full quantization is explicitly obtained for most of the Drinfel’d doubles, except a small number of them for which the dual Lie algebra is either sl2 or so(3). In the latter cases, the classical r-matrices underlying the Drinfel’d double quan...

Shared delusions of doubles.

This is the first report of two partners in a folie à deux situation manifesting identical Capgras delusions. It is postulated that the Capgras syndrome developed as a result of interaction between a dominant patient with primarily paranoid psychopathology and a submissive one with primarily organic dysfunction. The submissive "neuro-organic" partner experienced a non-delusional misidentificati...
