In this paper, we introduce a bisexual Galton-Watson branching process with mating function dependent on the population size in each generation. Necessary and sufficient conditions for the process to ...
The tracheal system of Drosophila melanogaster is one of the best characterized multicellular branched organs. Branchless (BNL), a fibroblast growth factor (FGF) ligand, initiates the branching ...
