Query: Entropy flux and Lagrange multipliers: information theory and
  thermodynamics   We analyze the relation between the nonequilibrium Lagrange multipliers used
in information theory and those used in Liu's technique to exploit the entropy
inequality. We observe that there is not a complete equivalence between Liu's
technique and information theory.
