Beauty-quark fragmentation-fraction ratio $f_{\rm s}/(f_{\rm u} + f_{\rm d})$ calculated from non-prompt D-meson measurements in pp collisions at $\s=13$ TeV comparedwith previous measurements from CDF , ALICE , ATLAS , CMS  and LHCb , with the average of LEP measurements , and with the results of PYTHIA 8.243 simulations with Monash-13 tune .
