Query: A higher speed type II blowup for the five dimensional energy critical
  heat equation   This paper is concerned with blow-up solutions of the five dimensional energy
critical heat equation $u_t=\Delta u+|u|^\frac{4}{3}u$. A goal of this paper is
to show the existence of type II blowup solutions which behave as
$\|u(t)\|_\infty\sim(T-t)^{-3k}$ ($k=2,3,\cdots$). Our solutions are the same
one formally derived by Filippas, Herrero and Vel\'azquez \cite{Filippas}.
