Query: Thermodynamically Anomalous Regions and Possible New Signals of Mixed
  Phase Formation   Using an advanced version of the hadron resonance gas model we have found
indications for irregularities in data for hadrons produced in relativistic
heavy-ion collisions. These include an abrupt change of the effective number of
degrees of freedom, a change of the slope of the ratio of lambda hyperons to
protons at laboratory energies 8.6--11.6 AGeV, as well as highly correlated
plateaus in the collision-energy dependence of the entropy per baryon, total
pion number per baryon, and thermal pion number per baryon at laboratory
energies 6.9-11.6 AGeV. Also, we observe a sharp peak in the dimensionless
trace anomaly at a laboratory energy of 11.6 AGeV. On the basis of the
generalized shock-adiabat model we demonstrate that these observations give
evidence for the anomalous thermodynamic properties of the mixed phase at its
boundary to the quark-gluon plasma. We argue that the trace-anomaly peak and
the local minimum of the generalized specific volume observed at a laboratory
energy of 11.6 AGeV provide a signal for the formation of a mixed phase between
the quark-gluon plasma and the hadron phase. This naturally explains the change
of slope in the energy dependence of the yield of lambda hyperons per proton at
a laboratory energy of 8.6 GeV.
