We observed that the increase of volume fraction generates a more complex depression, characterized by two angles of discharge: one at the bottom similar to th...

To this aim, a continuum macroscopic fluid domain is initially modeled as a Hamiltonian system of discrete particles, for which the interparticle dissipative forces are required to be radial in or...

One of these algorithms generaliz...

In particular, several details must still be finalized in the pathway from kinetic theory to hydrodynamics mainly in th...

The time scales after which equilibrium properties can be extracted are sufficie...

Trophallactic systems are typically treated as a network of agent interactions. Thi...

This process is spontaneous and driven by electrostatic interactions between positive domains on the virus coat proteins and the negative genomes. We model the effect of the nonuniform icosahedral charge di...
