Steinitz classes of unimodular lattices

For each prime l with l ≡ 7 (mod 8), we define an action of the ring O = Z[ 2(1 + √ −l)] on the unimodular lattice D l+1 using a Paley matrix. We determine the isomorphism class of D l+1 as an O-module. In particular we show that unless l = 7, D l+1 is not a free O-module. We note a consequence for the Leech lattice.

Evolution of Particle Accelerators & Colliders by WOLFGANG

WHEN J. J. THOMSON discovered the electron, he did not call the instrument he was using an accelerator, but an accelerator it certainly was. He accelerated particles between two electrodes to which he had applied a difference in electric potential. He manipulated the resulting beam with electric and magnetic fields to determine the charge-tomass ratio of cathode rays. Thomson achieved his disco...

Wolfgang Wahlster

In face-to-face conversation humans frequently use deictic gestures parallel to verbal descriptions for referent identification. Such a multimodal form of communication is of great importance for intelligent interfaces, because it simplifies and speeds up reference to objects in a visual context. Natural pointing behavior is very flexible, but possibly ambiguous or vague, so that without a care...
