Query: Baryon-Strangeness Correlations in Au+Au Collisions at
  $\sqrt{s_\mathrm{NN}}$=7.7-200 GeV from the UrQMD model   Fluctuations and correlations of conserved charges are sensitive observables
for studying the QCD phase transition and critical point in high-energy
heavy-ion collisions. We have studied the centrality and energy dependence of
mixed-cumulants (up to fourth order) between net-baryon and net-strangeness in
Au+Au collisions at $\sqrt{s_{NN}}$= 7.7, 11.5, 19.6, 27, 39, 62.4, 200 GeV
from UrQMD model. To compare with other theoretical calculations, we normalize
these mixed-cumulants by various order cumulants of net-strangeness
distributions. We found that the results obtained from UrQMD calculations are
comparable with the results from Lattice QCD at low temperature and hadron
resonance gas model. The ratios of mixed-cumulants
($R_{11}^{BS},R_{13}^{BS},R_{22}^{BS}$,~$R_{31}^{BS}$) from UrQMD calculations
show weak centrality dependence. However, the mixed-cumulant ratios
$R_{11}^{BS}$ and $R_{31}^{BS}$ show strong increase at low energy, while the
$R_{13}^{BS}$ snd $R_{22}^{BS}$ are similar at different energies. Furthermore,
we have also studied the correlations between different hadron species and
their contributions to the net-baryon and net-strangeness correlations. These
models studies can provide baselines for searching for the signals of QCD phase
transition and critical point in heavy-ion collisions.
