Query: Direct and Inverse Estimates for Combinations of Bernstein Polynomials
  with Endpoint Singularities   We give direct and inverse theorems for the weighted approximation of
functions with endpoint singularities by combinations of Bernstein polynomials
by the $r$th Ditzian-Totik modulus of smoothness $\omega_\phi^{r}(f,t)_w$ where
$\phi$ is an admissible step-weight function.
