Let T be a critical or subcritical Galton-Watson family tree with possibly infinite variance. We are interested in the shape of T conditioned to have a large total number of vertices. For this purpose we study random trees whose conditional distribution given their size is the same as the respective conditional distribution of T. These random family trees(More)
Branching processes exhibit a particularly rich longtime behaviour when evolving in a random environment. Then the transition from subcriticality to supercriticality proceeds in several steps, and there occurs a second ‘transition’ in the subcritical phase (besides the phase-transition from (sub)criticality to supercriticality). Here we present and discuss(More)
We present SCENIC simulations of aW7X 4He plasma with 1% Hminority and with an antenna model close to the design foreseen for the W7X ICRF antenna [1, 2]. A high mirror and a standard equilibrium are considered. The injected wave frequency is fixed at 33.8 MHz and 39.6MHz respectively and only fundamental minority heating is considered. Included in this(More)

Let T̂t be a critical binary continuous-time Galton-Watson tree size-biased according to the number of particles at time t. Decompose the population at t according to the particles’ degree of relationship with a distinguished particle picked purely at random from those alive at t. Keeping track of the times when the different families grow out of the(More)
