    "abstract": "It is argued that the dynamics of an isolated system, due to the concrete\nprocedure by which it is separated from the environment, has a non-Hamiltonian\ncontribution. By a unified quantum field theoretical treatment of typical\nsubdynamics, e.g., hydrodynamics, kinetic theory, master equation for a\nparticle interacting with matter, we look for the structure of this more\ngeneral dynamics.",
