Neural-Network Closures for Complex-Shaped Particles in the Force-Coupling Method
Marco Laudato
A data-driven surrogate framework to accelerate particle-resolved modelling of quasi-dilute suspensions of rigid, non-spherical particles in Stokes flow is introduced. A regularize…
A Neural-Operator Surrogate for Platelet Deformation Across Capillary Numbers
Marco Laudato
Reliable multiscale models of thrombosis require platelet-scale fidelity at organ-scale cost, a gap that scientific machine learning has the potential to narrow. We train a DeepONe…
Neural Operator Modeling of Platelet Geometry and Stress in Shear Flow
Marco Laudato, Luca Manzari, Khemraj Shukla
Thrombosis involves processes spanning large-scale fluid flow to sub-cellular events such as platelet activation. Traditional CFD approaches often treat blood as a continuum, which…
Sparse wavefield reconstruction and denoising with boostlets
Elias Zea, Marco Laudato, Joakim Andén
Boostlets are spatiotemporal functions that decompose nondispersive wavefields into a collection of localized waveforms parametrized by dilations, hyperbolic rotations, and transla…
High-Fidelity Description of Platelet Deformation Using a Neural Operator
Marco Laudato, Luca Manzari, Khemraj Shukla
The goal of this work is to investigate the capability of a neural operator (DeepONet) to accurately capture the complex deformation of a platelet's membrane under shear flow. The…
A boostlet transform for wave-based acoustic signal processing in space-time
Elias Zea, Marco Laudato, Joakim Andén
Sparse representation systems that encode signal architecture have had a profound impact on sampling and compression paradigms. Remarkable examples are multi-scale directional syst…
Sound generation mechanisms in a collapsible tub
Marco Laudato, Elias Zea, Elias Sundström +2
Collapsible tubes can be employed to study the sound generation mechanism in the human respiratory system. The goals of this work are (a) to determine the airflow characteristics c…
Covariant Momentum Map Thermodynamics for Parametrized Field Theories
Goffredo Chirco, Marco Laudato, Fabio M. Mele
A general-covariant statistical framework capable of describing classical fluctuations of the gravitational field is a thorny open problem in theoretical physics, yet ultimately ne…
A Pedagogical Intrinsic Approach to Relative Entropies as Potential Functions of Quantum Metrics: the - Family
Florio M. Ciaglia, Fabio Di Cosmo, Marco Laudato +4
The so-called -z-\textit{Rényi Relative Entropies} provide a huge two-parameter family of relative entropies which includes almost all well-known examples of quantum relative en…
Dynamical Vector Fields on the Manifold of Quantum States
Florio M. Ciaglia, Fabio Di Cosmo, Alberto Ibort +2
In this paper we shall consider the stratified manifold of quantum states and the vector fields which act on it. In particular, we show that the infinitesimal generator of the GKLS…
Differential Calculus on Manifolds with a Boundary. Applications
Florio Maria Ciaglia, Fabio Di Cosmo, Marco Laudato +1
This paper contains a set of lecture notes on manifolds with boundary and corners, with particular attention to the space of quantum states. A geometrically inspired way of dealing…
Tomographic Reconstruction of Quantum Metrics
Marco Laudato, Giuseppe Marmo, Fabio M. Mele +2
In the framework of quantum information geometry we investigate the relationship between monotone metric tensors uniquely defined on the space of quantum tomograms, once the tomogr…
Interaction from Geometry, Classical and Quantum
M. Laudato
In this work, we have studied classical and quantum systems in interaction by means of geometric reduction procedure. The main target is the description in these terms of fundament…
