  The ultraviolet completion of a large N QCD model requires introducing new
degrees of freedom at certain scale so that the UV behavior may become
asymptotically conformal with no Landau poles and no UV divergences of Wilson
loops. These UV degrees of freedom are represented by certain anti-branes
arranged on the blown-up sphere of a warped resolved conifold in a way that
they are separated from the other set of branes that control the IR behavior of
the theory. This separation of the branes and the anti-branes creates
instability in the theory. Further complications arise from the curvature of
the ambient space. We show that, despite these analytical hurdles, stability
may still be achieved by switching on appropriate world-volume fluxes on the
branes. The UV degrees of freedom, on the other hand, modify the RG flow in the
model. We discuss this in details by evaluating the flow from IR confining to
UV conformal. Finally we lay down a calculational scheme to study bulk
viscosity which, in turn, would signal the inherent non-conformality in this
model.
