Query: One-dimensional diffusion processes with moving membrane: partial
  reflection in combination with jump-like exit of process from membrane   We use analytical methods to construct the two-parameter Feller semigroup
associated with a Markov process on a line with a moving membrane such that at
the points on both sides of the membrane it coincides with the ordinary
diffusion processes given there and its behavior after reaching the membrane is
described by a kind of nonlocal Feller-Wentzell conjugation condition.
