Query: On a polynomial positivity question of Collins, Dykema, and Torres-Ayala
  related to the Bessis-Moussa-Villani Conjecture   We construct sum of squares certificates of non-negativity for two families
of polynomials appearing as a variant by Collins, Dykema, and Torres-Ayala to
H\"aegele's reformulation of a conjecture by Bessis, Moussa, and Villani.
