Tethered Semiflexible Polymer under Large Amplitude Oscillatory Shear
Antonio Lamura, Roland G. Winkler
The properties of a semiflexible polymer with fixed ends exposed to oscillatory shear flow are investigated by simulations. The two-dimensionally confined polymer is modeled as a l…
Sheared phase-separating binary mixtures with surface diffusion
G. Gonnella, A. Lamura
The phase-separation process of a binary mixture with order-parameter-dependent mobility under shear flow is numerically studied. The ordering is characterized by an alternate stre…
Wall-anchored semiflexible polymer under large amplitude oscillatory shear flow
Antonio Lamura, Roland G. Winkler, Gerhard Gompper
The properties of semiflexible polymers tethered by one end to an impenetrable wall and exposed to oscillatory shear flow are investigated by mesoscale simulations. A polymer, conf…
Gravitomagnetic Helicity
Donato Bini, Bahram Mashhoon, Yuri N. Obukhov
Mass currents in astrophysics generate gravitomagnetic fields of enormous complexity. Gravitomagnetic helicity, in direct analogy with magnetic helicity, is a measure of entwining…
Shearing effects on the phase coarsening of binary mixtures using the Active Model B
A. Lamura, A. Tiribocchi
The phase separation of a two-dimensional active binary mixture is studied under the action of an applied shear through numerical simulations. It is highlighted how the strength of…
Cassini and extra force constraints to nonminimally coupled gravity with screening mechanism
Riccardo March, Orfeu Bertolami, Marco Muccino +2
We consider a nonminimally coupled curvature-matter gravity theory at the Solar System scale. Both a fifth force of Yukawa type and a further non-Newtonian extra force that arises…
Petrov type I spacetime curvature: principal null vector spanning dimension
Donato Bini, Andrea Geralico, Robert T. Jantzen
The class of Petrov type I curvature tensors is further divided into those for which the span of the set of distinct principal null directions has dimension four (maximally spannin…
A quantitative comparison of physical accuracy and numerical stability of Lattice Boltzmann color gradient and pseudopotential multicomponent models for microfluidic applications
Karun P. N. Datadien, Gianluca Di Staso, Herman M. A. Wijshoff +1
The performances of the Color-Gradient (CG) and of the Shan-Chen (SC) multicomponent Lattice Boltzmann models are quantitatively compared side-by-side on multiple physical flow pro…
Nonlocal diffusion of variable order on complex networks
Daniele Bertaccini, Fabio Durastante
Some aspects of nonlocal dynamics on directed and undirected networks for an initial value problem whose Jacobian matrix is a variable-order fractional power of a Laplacian matrix…
TLBfind: a Thermal Lattice Boltzmann code for concentrated emulsions with FINite-size Droplets
Francesca Pelusi, Matteo Lulli, Mauro Sbragaglia +1
In this paper, we present TLBfind, a GPU code for simulating the hydrodynamics of droplets along with a dynamic temperature field. TLBfind hinges on a two-dimensional multi-compone…
Frequency domain analysis of the gravitational wave energy loss in hyperbolic encounters
Donato Bini, Andrea Geralico
The energy radiated (without the 1.5PN tail contribution which requires a different treatment) by a binary system of compact objects moving in a hyperboliclike orbit is computed in…
Deformation and breakup dynamics of droplets within a tapered channel
Andrea Montessori, Michele La Rocca, Pietro Prestininzi +2
In this paper we numerically investigate the breakup dynamics of droplets in an emulsion flowing in a tapered microchannel with a narrow constriction. The mesoscale approach for mu…
Higher-order tail contributions to the energy and angular momentum fluxes in a two-body scattering process
Donato Bini, Andrea Geralico
The need for more and more accurate gravitational wave templates requires taking into account all possible contributions to the emission of gravitational radiation from a binary sy…
A generalized mean-field game model for the dynamics of pedestrians with limited predictive abilities
Emiliano Cristiani, Arianna De Santo, Marta Menci
This paper investigates the model for pedestrian flow firstly proposed in [Cristiani et al., DOI:10.1137/140962413]. The model assumes that each individual in the crowd moves in a…

The state-of-the-art deep learning-based object recognition YOLO algorithm and object tracking DeepSORT algorithm are combined to analyze digital images from fluid dynamic simulati…
Radiative contributions to gravitational scattering
Donato Bini, Thibault Damour, Andrea Geralico
The linear-order effects of radiation-reaction on the classical scattering of two point masses, in General Relativity, are derived by a variation-of-constants method. Explicit expr…
Friction-enhanced lifetime of bundled quantum vortices
Luca Galantucci, Giorgio Krstulovic, Carlo F. Barenghi
Experiments in the early 1980s have shown that a compact bundle of quantum vortex rings in superfluid helium remains coherent and travels a significant distance compared to its siz…
A non-standard numerical scheme for an age-of-infection epidemic model
Eleonora Messina, Mario Pezzella, Antonia Vecchio
We propose a numerical method for approximating integro-differential equations arising in age-of-infection epidemic models. The method is based on a non-standard finite differences…

Maya Briani, Emiliano Cristiani, Paolo Ranut
In this paper we propose two models describing the dynamics of heavy and light vehicles on a road network, taking into account the interactions between the two classes. The models…
