The effect of expansion ratio for creeping expansion flows of UCM fluids [PDF]

open access: yesJournal of Non-Newtonian Fluid Mechanics, 2009
A systematic numerical investigation on creeping flows in planar sudden expansions of viscoelastic fluids obeying the upper-convected Maxwell model is carried out to assess the combined effects of viscoelasticity, through the Deborah number, and expansion ratio (ER), which was varied between 1.25 and 32.

Hard Three-Loop Corrections to Hyperfine Splitting in Positronium and Muonium [PDF]

open access: yes, 2015
We consider hard three-loop corrections to hyperfine splitting in muonium and positronium generated by the diagrams with closed electron loops. There are six gauge-invariant sets of such diagrams that generate corrections of order $m\alpha^7$.

On the asymptotic expansion of a ratio of gamma functions

open access: yesJournal of Mathematical Analysis and Applications, 2012
AbstractWe study the problem of the asymptotic expansion of the ratio of two gamma functions Γ(x+α)/Γ(x+β) as x→+∞, α,β⩾0. In particular, an alternate asymptotic formula with respect to the ones known in literature is given.
