Cylindrical gravitational waves: C-energy, super-energy and associated dynamical effects
Donato Bini, Andrea Geralico, Wolfango Plastino
The energy content of cylindrical gravitational wave spacetimes is analyzed by considering two local descriptions of energy associated with the gravitational field, namely those ba…
Nonlinear-in-spin effects in effective-one-body waveform models of spin-aligned, inspiralling, neutron star binaries
Alessandro Nagar, Francesco Messina, Piero Rettegno +5
Spinning neutron stars acquire a quadrupole moment due to their own rotation. This quadratic-in-spin, self-spin effect depends on the equation of state (EOS) and affects the orbita…
Jetting to dripping transition: critical aspect ratio in step emulsifiers
Andrea Montessori, Marco Lauricella, Elad Stolovicki +2
Fully three-dimensional, time-dependent, direct simulations of the non-ideal Navier-Stokes equations for a two-component fluid, shed light into the mechanism which inhibits droplet…
Rational Krylov methods for functions of matrices with applications to fractional partial differential equations
Lidia Aceto, Daniele Bertaccini, Fabio Durastante +1
In this paper, we propose a new choice of poles to define reliable rational Krylov methods. These methods are used for approximating function of positive definite matrices. In part…
On weak regularity requirements of the relaxation modulus in viscoelasticity
Sandra Carillo, Michel Chipot, Vanda Valente +1
The existence and uniqueness of solution to a one-dimensional hyperbolic integro-differential problem arising in viscoelasticity is here considered. The kernel, in the linear visco…
A lattice Boltzmann method for thin liquid film hydrodynamics
Stefan Zitz, Andrea Scagliarini, Suryanarayana Maddu Kondaiah +2
We propose a novel approach to the numerical simulation of thin film flows, based on the lattice Boltzmann method. We outline the basic features of the method, show in which limits…
Reaction fronts in persistent random walks with demographic stochasticity
Davide Vergni, Stefano Berti, Angelo Vulpiani +1
Standard Reaction-Diffusion (RD) systems are characterized by infinite velocities and no persistence in the movement of individuals, two conditions that are violated when consideri…
On the energy content of electromagnetic and gravitational plane waves through super-energy tensors
Donato Bini, Andrea Geralico
The energy content of (exact) electromagnetic and gravitational plane waves is studied in terms of super-energy tensors (the Bel, Bel-Robinson and the --less familiar-- Chevreton t…
Gravitational self-force corrections to gyroscope precession along circular orbits in the Kerr spacetime
Donato Bini, Thibault Damour, Andrea Geralico +2
We generalize to Kerr spacetime previous gravitational self-force results on gyroscope precession along circular orbits in the Schwarzschild spacetime. In particular we present hig…
Modelling sea ice and melt ponds evolution: sensitivity to microscale heat transfer mechanisms
Andrea Scagliarini, Enrico Calzavarini, Daniela Mansutti +1
We present a mathematical model describing the evolution of sea ice and meltwater during summer. The system is described by two coupled partial differential equations for the ice t…
Effect of flow on ATP/ADP concentration at the endothelial cell surface: interplay between shear stress and mass transport
Ezio Di Costanzo, Abdul I. Barakat, Giuseppe Pontrelli
The nucleotides ATP and ADP regulate many aspects of endothelial cell (EC) biology, including intracellular calcium concentrations, focal adhesion activation, cytoskeletal organiza…
Hyperbolic-like elastic scattering of spinning particles by a Schwarzschild black hole
Donato Bini, Andrea Geralico
The scattering of spinning test particles by a Schwarzschild black hole is studied. The motion is described according to the Mathisson-Papapetrou-Dixon model for extended bodies in…
Relative-observer definition of the Simon tensor
Donato Bini, Andrea Geralico
The definition of Simon tensor, originally given only in the Kerr spacetime and associated with the static family of observers, is generalized to any spacetime and to any possible…
Schwarzschild black hole embedded in a dust field: scattering of particles and drag force effects
Donato Bini, Andrea Geralico
A "temporal analogue" of the standard Poynting-Robertson effect is analyzed as induced by a dust of particles (instead of a gas of photons) surrounding a Schwarzschild black hole.…
Scattering by a Schwarzschild black hole of particles undergoing drag force effects
Donato Bini, Andrea Geralico
The scattering of massive particles by a Schwarzschild black hole also undergoing a drag force is considered. The latter is modeled as a viscous force acting on the orbital plane,…
Optimal Lebesgue constants for least squares polynomial approximation on the (hyper)sphere
Woula Themistoclakis, Marc Van Barel
We investigate the uniform approximation provided by least squares polynomials on the unit Euclidean sphere in , with . Like any other poly…
Virtualization Technologies and Cloud Security: advantages, issues, and perspectives
Roberto Di Pietro, Flavio Lombardi
Virtualization technologies allow multiple tenants to share physical resources with a degree of security and isolation that cannot be guaranteed by mere containerization. Further,…
Fixation Probabilities in Weakly Compressible Fluid Flows
Abigail Plummer, Roberto Benzi, David R. Nelson +1
Competition between biological species in marine environments is affected by the motion of the surrounding fluid. An effective 2D compressibility can arise, for example, from the c…
Black hole geodesic parallel transport and the Marck recipe for isolating cumulative precession effects
Donato Bini, Andrea Geralico, Robert T. Jantzen
The Wigner rotations arising from the combination of boosts along two different directions are rederived from a relative boost point of view and applied to gyroscope spin precessio…
Prospects for the detection of electronic pre-turbulence in graphene
A. Gabbana, M. Polini, S. Succi +2
Based on extensive numerical simulations, accounting for electrostatic interactions and dissipative electron-phonon scattering, we propose experimentally realizable geometries capa…
Mesoscale modelling of soft flowing crystals
Andrea Montessori, Marco Lauricella, Sauro Succi
We outline the main ideas behind the numerical modelling of soft-flowing crystals, with special attention to their application to microfluidic devices for the design of novel mesos…

Federico Fadda, Giuseppe Gonnella, Antonio Lamura +2
The dynamics of a quasi two-dimensional isotropic droplet in a cholesteric liquid crystal medium under symmetric shear flow is studied by lattice Boltzmann simulations. We consider…
Twisted Gravitational Waves of Petrov Type D
Kjell Rosquist, Donato Bini, Bahram Mashhoon
Twisted gravitational waves (TGWs) are nonplanar unidirectional Ricci-flat solutions of general relativity. Thus far only TGWs of Petrov type \emph{II} are implicitly known that de…
