Query: Gradient Estimate for the Heat Kernel on Some Fractal-Like Cable Systems
  and Quasi-Riesz Transforms   We give pointwise upper estimate for the gradient of the heat kernel on some
fractal-like cable systems including the Vicsek and the Sierpi\'nski cable
systems. Applications to $L^p$-boundedness of quasi-Riesz transforms are
derived.
