Query: Hydro-inspired parameterizations of freeze-out in relativistic heavy-ion
  collisions   Popular parameterizations of the freeze-out conditions in relativistic
heavy-ion collisions are discussed. Similarities and differences between the
blast-wave model and the single-freeze-out model, both used recently to
interpret the RHIC data, are outlined. A non-boost-invariant extension of the
single-freeze-out model is proposed and applied to describe the recent BRAHMS
data.
