Query: Triplet pairing and upper critical field in the mixed state of d-wave
  superconductors   We show that an additional triplet component of the order parameter is
generated in the vortex phase of the d-wave superconductor. Spatial variations
of the triplet component are analyzed for a strong spin-orbit coupling.
Corrections to the London equation and an unusual temperature dependence of the
upper critical field, are obtained in the case of the weak spin-orbit coupling.
