Query: Closure of the algebra of constraints for a nonprojectable Ho\v{r}ava
  model   We perform the Hamiltonian analysis for a nonprojectable Horava model whose
potential is composed of R and R^2 terms. We show that Dirac's algorithm for
the preservation of the constraints can be done in a closed way, hence the
algebra of constraints for this model is consistent. The model has an extra,
odd, scalar mode whose decoupling limit can be seen in a linear-order
perturbative analysis on weakly varying backgrounds.
  Although our results for this model point in favor of the consistency of the
Ho\v{r}ava theory, the validity of the full nonprojectable theory still remains
unanswered.
