Mathematical modelling of drug delivery from pH-responsive nanocontainers
G. Pontrelli, G. Toniolo, S. McGinty +3
Drug delivery systems represent a promising strategy to treat cancer and to overcome the side effects of chemotherapy. In particular, polymeric nanocontainers have attracted major…
Mathematical models and methods for crowd dynamics control
Giacomo Albi, Emiliano Cristiani, Lorenzo Pareschi +1
In this survey we consider mathematical models and methods recently developed to control crowd dynamics, with particular emphasis on egressing pedestrians. We focus on two control…
Dissipative hydrodynamics of relativistic shock waves in a Quark Gluon Plasma: comparing and benchmarking alternate numerical methods
A. Gabbana, S. Plumari, G. Galesi +4
This paper presents numerical cross-comparisons and benchmark results for two different kinetic numerical methods, capable of describing relativistic dissipative fluid dynamics in…
Nonlocal network dynamics via fractional graph Laplacians
Michele Benzi, Daniele Bertaccini, Fabio Durastante +1
We introduce nonlocal dynamics on directed networks through the construction of a fractional version of a nonsymmetric Laplacian for weighted directed graphs. Furthermore, we provi…
New solutions of the Ermakov-Pinney equation in curved space-time
Donato Bini, Giampiero Esposito
An Ermakov-Pinney-like equation associated with the scalar wave equation in curved space-time is here studied. The example of Schwarzschild space-time considered in the present wor…
Discrete fluidization of dense monodisperse emulsions in neutral wetting microchannels
Linlin Fei, Andrea Scagliarini, Kai H. Luo +1
The rheology of pressure-driven flows of two-dimensional dense monodisperse emulsions in neutral wetting microchannels is investigated by means of mesoscopic lattice simulations, c…
Comparing Effective One Body Hamiltonians for spin-aligned coalescing binaries
Piero Rettegno, Fabio Martinetti, Alessandro Nagar +3
TEOBResumS and SEOBNRv4 are the two existing semi-analytical gravitational waveform models for spin-aligned coalescing black hole binaries based on the effective-one-body approach.…
Novel non-equilibrium steady states in multiple emulsions
A. Tiribocchi, A. Montessori, S. Aime +4
We numerically investigate the rheological response of a non-coalescing multiple emulsion under a symmetric shear flow. We find that the dynamics significantly depends on the magni…
Lattice Propagators and Haldane-Wu Fractional Statistics
Sauro Succi, Marco Lauricella
We point out a formal analogy between lattice kinetic propagators and Haldane-Wu fractional statistics. The analogy could be used to compute the partition function of fractional qu…
Probing bulk viscosity in relativistic flows
A. Gabbana, D. Simeoni, S. Succi +1
We derive an analytical connection between kinetic relaxation rate and bulk viscosity of a relativistic fluid in d spatial dimensions, all the way from the ultra-relativistic down…
Rheology of active polar emulsions: from linear to unidirectional and unviscid flow, and intermittent viscosity
Giuseppe Negro, Livio Nicola Carenza, Antonio Lamura +2
The rheological behaviour of an emulsion made of an active polar component and an isotropic passive fluid is studied by lattice Boltzmann methods. Different flow regimes are found…
Neural Network Models for the Anisotropic Reynolds Stress Tensor in Turbulent Channel Flow
Rui Fang, David Sondak, Pavlos Protopapas +1
Reynolds-averaged Navier-Stokes (RANS) equations are presently one of the most popular models for simulating turbulence. Performing RANS simulation requires additional modeling for…
Novel approach to binary dynamics: application to the fifth post-Newtonian level
Donato Bini, Thibault Damour, Andrea Geralico
We introduce a new methodology for deriving the conservative dynamics of gravitationally interacting binary systems. Our approach combines, in a novel way, several theoretical form…

Guillaume Duclos, Raymond Adkins, Debarghya Banerjee +13
Point-like motile topological defects control the universal dynamics of diverse two-dimensional active nematics ranging from shaken granular rods to cellular monolayers. A comparab…

Kim M. J. Alards, Rudie P. J. Kunnen, Richard J. A. M. Stevens +3
In RB convection for fluids with Prandtl number , rotation beyond a critical (small) rotation rate is known to cause a sudden enhancement of heat transfer which can be…
Strong ergodicity breaking in aging of mean field spin glasses
Massimo Bernaschi, Alain Billoire, Andrea Maiorano +2
