Query: Residue cross sections of $^{50}$Ti-induced fusion reactions based on
  the two-step model   $^{50}$Ti-induced fusion reactions to synthesize superheavy elements are
studied systematically with the two-step model developed recently, where fusion
process is divided into approaching phase and formation phase. Furthermore, the
residue cross sections for different neutron evaporation channels are evaluated
with the statistical evaporation model. In general, the calculated cross
sections are much smaller than that of $^{48}$Ca-induced fusion reactions, but
the results are within the detection capability of experimental facilities
nowadays. The maximum calculated residue cross section for producing superheavy
element $Z=119$ is in the reaction $^{50}$Ti+$^{247}$Bk in $3n$ channels with
$\sigma_{\rm res}(3n)=0.043$ pb at $E^{*}$ = 37.0 MeV.
