Query: Non-local Branching Superprocesses and Some Related Models   A new formulation of non-local branching superprocesses is given from which
we derive as special cases the rebirth, the multitype, the mass-structured, the
multilevel and the age-reproduction-structured superprocesses and the
superprocess-controlled immigration process. This unified treatment simplifies
considerably the proof of existence of the old classes of superprocesses and
also gives rise to some new ones.
