Type of finite time singularities of the Ricci flow with bounded scalar curvature

In this paper, we study the Ricci flow on a closed manifold of dimension $n \ge 4$andfinitetimeinterval$[0,T)~(T < \infty)$ on which the scalar curvature are uniformly bounded. We prove that if such flow of dimension $4 \le n \le 7$ has finite time singularities, then every blow-up sequence of a locally Type I singularity has certain property. Here, locally Type I singularity is what Buzano and Di-Matteo defined.
