Query: Bloch-Ogus theory for smooth and semi-stable schemes in mixed
  characteristic   We study Bloch-Ogus theory and the Gersten conjecture for smooth and
semi-stable schemes in mixed characteristic. We prove the Gersten conjecture in
the smooth case and prove some special cases in the semi-stable situation.
