Query: Stability analysis and Observational Measurement in Chameleonic
  Generalised Brans--Dicke Cosmology   We investigate the dynamics of the chameleonic Generalised Brans--Dicke model
in flat FRW cosmology. In a new approach, a framework to study stability and
attractor solutions in the phase space is developed for the model by
simultaneously best fitting the stability and model parameters with the
observational data. The results show that for an accelerating universe the
phantom crossing does not occur in the past and near future.
