Query: Recent results from the UrQMD hybrid model for heavy ion collisions   These proceedings present recent results from transport-hydrodynamics-hybrid
models for heavy ion collisions at relativistic energies. The main focus is on
the absorption of (anti-)protons in the hadronic afterburner stage of the
reaction, di-lepton production at SPS and heavy quark dynamics.
