      abstract     = {In this work we study the behavior of mesoscopic
                      fluctuations of a fluid simulated by Multiparticle Collision
                      Dynamics when this is applied together with a local
                      thermostatting procedure that constrains the strength of
                      temperature fluctuations. We consider procedures in which
                      the thermostat interacts with the fluid at every simulation
                      step as well as cases in which the thermostat is applied
                      only at regular time intervals. Due to the application of
                      the thermostat temperature fluctuations are forced to relax
                      to equilibrium faster than they do in the nonthermostatted,
                      constant-energy case. Depending on the interval of
                      application of the thermostat, it is demonstrated that the
                      thermodynamic state changes gradually from isothermal to
                      adiabatic conditions. In order to exhibit this effect we
                      compute from simulations diverse correlation functions of
                      the hydrodynamic fluctuating fields. These correlation
                      functions are compared with those predicted by a linearized
                      hydrodynamic theory of a simple fluid in which a thermostat
                      is applied locally. We find a good agreement between the
                      model and the numerical results, which confirms that
                      hydrodynamic fluctuations in Multiparticle Collision
                      Dynamics in the presence of the thermostat have the
                      properties expected for spontaneous fluctuations in fluids
                      in contact with a heat reservoir.},
