TESLA is one of the design proposals for a TeV range linear electron positron collider. The electrons and positrons will collide in bunch trains with a rate of 5 Hz and each train itself will consist of 2820 bunches. The bunch to bunch distance within the train is 337 ns resulting in a total train length of about 1 ms. This operation mode requires a deadtime free data taking within 1 ms. In con...

Localization was measured for nearby sources with abrupt or slow rise/fall times in a reverberant space. A recent model of distance perception @A. W. Bronkhorst and T. Houtgast, Nature 397, 517–520 ~1999!# suggests that perceived distance is computed from the room impulse response. The model assumes that energy in the onset of the impulse response ~primarily from the direct sound, varying with ...

Background and aims: Diabetes type II (non-insulin dependent) which is one of the most prevalent diabetes types in the world emerges in people with the age of above 55 and genetic and environmental factors interfere in this disease. The aim of this study was to determine the factors affecting diabetes type II with generalized mixed linear model. Methods: ...
