Query: Inverse nodal problem for Dirac operator with integral type nonlocal
  boundary conditions   In this paper, Dirac operator with some integral type nonlocal boundary
conditions is studied. We show that the coefficients of the problem can be
uniquely determined by a dense set of nodal points. Moreover, we give an
algorithm for the reconstruction of some coefficients of the operator.
