Query: Generalized symmetric nonextensive thermostatistics and q-modified
  structures   We formulate a convenient generalization of the q-expectation value, based on
the analogy of the symmetric quantum groups and q-calculus, and show that the
q->q^{-1} symmetric nonextensive entropy preserves all of the mathematical
structure of thermodynamics just as in the case of non-symmetric Tsallis
statistics. Basic properties and analogies with quantum groups are discussed.
