A numerical study to analyze the interplay of Weissenberg number and viscosity ratio in a log-strain tensorial model for viscoelastic fluids
Nehal Dash, Ramon Codina, Giulio G. Giusteri
We present a computational study aimed at exploring the different and independent roles of the Weissenberg number and of the ratio between the polymeric and solvent viscosity contr…
Inertial motion of incompressible continua
Francesca Berlinghieri, Giulio G. Giusteri
We study the inertial motion of incompressible continua within a geometric and variational framework, extending the classical Arnold-Ebin-Marsden theory from the group of volume-pr…
Morphogenesis driven by nematic defects in active biological networks
Silvia Paparini, Giulio G. Giusteri, L. Angela Mihai
Cellular morphogenesis, the process by which biological tissues acquire shape and structure, remains a fundamental challenge in understanding pattern formation and the coordinated…
Variationally mimetic operator network approach to transient viscous flows
Laura Rinaldi, Giulio Giuseppe Giusteri
The Variationally Mimetic Operator Network (VarMiON) approach is a machine learning technique, originally developed to predict the solution of elliptic differential problems, that…
Modelling the passive and active response of skeletal muscles within the adapted Voigt representation framework
Sara Galasso, Giulio G. Giusteri
We present a constitutive model for the passive and active response of skeletal muscles. At variance with more classical approaches, the model is developed exploiting adapted Voigt…
On the Noisy Road to Open Quantum Dynamics: The Place of Stochastic Hamiltonians
Pietro De Checchi, Federico Gallina, Barbara Fresch +1
Stochastic evolution underpins several approaches to the dynamics of open quantum systems, such as random modulation of Hamiltonian parameters, the stochastic Schrodinger equation…
