It is by now well-recognised that the na\"ive application of projection postulate on composite quantum systems can induce signalling between their constituent components, indicative a breakdown causality in relativistic spacetime context. Here we introduce necessary and sufficient condition for an ideal measurement observable to be non-signalling. As well as being particularly simple, it genera...

Most current work on spoken human-computer interaction has so far concentrated on interactions between a single user and a dialogue system. The advent of ideas of the computer or dialogue system as a conversational partner in a group of humans, for example within the CHIL-project and elsewhere (e.g. Kirchhoff & Ostendorf, 2003), introduces new requirements on the capabilities of the dialogue sy...

You will understand the title at one level by knowing that I have been a fan of the Boston Red Sox for about seventy years. This loyalty was partially rewarded about seventeen years ago when by chance I had the pleasure of spending an hour with my boyhood hero, Ted Williams. At about the time that I started to follow the Red Sox games by radio, I acquired the notion that I would like someday to...

We present n-dimensional vortex-ring-like and potential-like solutions with unusual properties related to some elliptical differential equations with compact sources. Solutions have almost 3-or 2-dimensional behaviour in the spaces with arbitrary (large) odd and even dimensions, respectively.

Unfamiliar line drawings were presented to subjects three times during BOLD fMRI scanning. A set of brain areas was detected in which the effect of stimulus repetition on the evoked fMRI response depended on whether or not the drawing could be conceived as a coherent three-dimensional structure. Differential repetition effects were found in the neural response to drawings of both structurally p...
