Given tex (Format: Strange bug):
  Therefore, in that case the observed dynamics cannot be truly
  Markovian. We can still approximately capture the observed density dynamics
  with eq.~\ref{eq:fpe}; however the local coefficients are then effectively
  averages over the co-evolving unobserved distribution. For example, $\vec
  v(\vec x,t)=\int p(\vec x^u|\vec x,t)v(\vec x,\vec x^u,t)dx^u$. This has some
  important consequences. First, the effective Markovian coefficients $\vec v,
  \lambda, D$, will generally depend on time, reflecting the time evolution of
  the hidden $p(\vec x^u)$ over the time scale of the experiment. Second, the
  effective coefficients may also depend on the initial condition: a cell
  population started concentrated around label $\vec x_0$ implies a certain
  distribution over $x^u$ when sampled at label $\vec x$ some time later; another
  population started around $\vec x_1$ carries a different history when it, too,
  visits $\vec x$ later. Therefore, for instance the effective drift $\vec v(\vec
  x)$ will be different in the two cases. We conclude that, if unobserved degrees
  of freedom have dynamics on the time scale of the experiment eq.~\ref{eq:fpe}
  is an approximation whose coefficients become \emph{non-universal} (dependent
  on intial conditions) and \emph{time-dependent}.
