We report the first measurement of the inclusive $\sigma(e^+e^-\to b\bar{b}\to D_s^+X)$ and $\sigma(e^+e^-\to b\bar{b}\to D^0/\bar{D}^0X)$ cross sections in the energy range from 10.63 to 11.02 GeV. Based on these results we determine $\sigma(e^+e^-\to B_s^0\bar{B}_s^0 X)$ and $\sigma(e^+e^-\to B\ba ...
