Query: A non-linear Renewal Theorem with stationary and slowly changing
  perturbations   Non-linear renewal theory is extended to include random walks perturbed by
both a slowly changing sequence and a stationary one. Main results include a
version of the Key Renewal Theorem, a derivation of the limiting distribution
of the excess over a boundary, and an expansion for the expected first passage
time. The formulation is motivated by problems in sequential analysis with
staggered entry, where subjects enter a study at random times.
