      abstract     = {The production yields of non-prompt $\mathrm{D}_{s}^{+}$
                      mesons, namely $\mathrm{D}_{s}^{+}$ mesons from
                      beauty-hadron decays, were measured for the first time as a
                      function of the transverse momentum ($p_{T}$) at midrapidity
                      ($|y|<0.5$) in central and semi-central Pb--Pb collisions at
                      a centre-of-mass energy per nucleon pair
                      $\sqrt{s_{NN}}=5.02~$TeV with the ALICE experiment at the
                      LHC.The $\mathrm{D}_{s}^{\pm}$ mesons were reconstructed
                      from the hadronic decay channel $\rm D_s^{+}\to \phi\pi^+$,
                      with $\rm \phi\to K^-K^+$, in the $4 < p_{T} < 36$GeV/$c$
                      and $2 < p_{T} < 24~$GeV/$c$ intervals for the 0--10\\% and
                      30--50\\% centrality classes, respectively.The measured
                      yields of non-prompt $\mathrm{D}_{s}^{+}$ mesons are
                      compared to those of prompt $\mathrm{D}_{s}^{+}$ and
                      non-prompt $\mathrm{D}^{0}$ mesons by calculating the ratios
                      of the production yields in Pb--Pb collisions and the
                      nuclear modification factor Raa. The ratio between the Raa
                      of non-prompt $\mathrm{D}_{s}^{+}$ and prompt
                      $\mathrm{D}_{s}^{+}$ mesons, and that between the Raa of
                      non-prompt $\mathrm{D}_{s}^{+}$ and non-prompt
                      $\mathrm{D}^{0}$ mesons in central Pb--Pb collisions are
                      found to be on average higher than unity in the $4 < p_{T} <
                      12~$GeV/$c$ interval with a statistical significance of
                      about $1.6\,\sigma$ and $1.7\,\sigma$, respectively. The
                      measured Raa ratios are compared with the predictions of
                      theoretical models of heavy-quark transport in a
                      hydrodynamically expanding QGP that incorporate
                      hadronisation via quark recombination.},
