14. ij. These forces depend on the positions of all neighbouring particles. Hence, they neither derive from a pair-wise additive potential as in standard DPD nor reduce to global density-dependent forces.
15. c and zero otherwise. Such a choice is made to favor a smoother local structure (S. Merabia, I. Pagonabarraga, in preparation) and differs from the standard quadratic weight function appearing in the DPD friction force.
16. Density oscillations at liquid/vapor interfaces have been reported in a variety of fluid models, and are attributed usually to the presence of a Fisher-Widom line (see, e.g., P. Tarazona, E. Chacon, M. Reinaldo-Falagan, E. Velasco, J. Chem. Phys. 117, 3941 (2002)).

22. If we assume that the line tension can be approximated as the surface tension associated to the interfacial width (see, e.g., S. Auer, D. Frenkel, Phys. Rev. Lett. 91, 015703 (2003)), the line and surface tensions contributions to the free energy become comparable when the area of the contact line is of the order of the contact area, consistent with simulation results.

24. Other forms of the fluid/wall net interaction (such as a density-dependent force) may lead to non-monotonous interfacial free energies and to the existence of a thin-film layer in coexistence with the drop.
