NeuralSim: Augmenting Differentiable Simulators with Neural Networks [PDF]

open access: yesIEEE International Conference on Robotics and Automation, 2020
Differentiable simulators provide an avenue for closing the sim-to-real gap by enabling the use of efficient, gradient-based optimization algorithms to find the simulation parameters that best fit the observed sensor readings.

Slow invariant manifolds as curvature of the flow of dynamical systems [PDF]

open access: yes, 2014
Considering trajectory curves, integral of n-dimensional dynamical systems, within the framework of Differential Geometry as curves in Euclidean n-space, it will be established in this article that the curvature of the flow, i.e.

Lectures on Structural Stability in Dynamics

open access: yes, 2017
These lectures present results and problems on the characterization of structurally stable dynamics. We will shed light those which do not seem to depend on the regularity class (holomorphic or differentiable).

A stochastic-hydrodynamic model of halo formation in charged particle beams [PDF]

open access: yes, 2003
The formation of the beam halo in charged particle accelerators is studied in the framework of a stochastic-hydrodynamic model for the collective motion of the particle beam.

Lyapunov exponent for Lipschitz maps

open access: yes, 2018
It is well-known that the Lyapunov exponent plays a fundamental role in dynamical systems. In this note, we propose an alternative definition of Lyapunov exponent in terms of Lipschitz maps, which are not necessarily differentiable.

Random Dynamical Systems for Stochastic Evolution Equations Driven by Multiplicative Fractional Brownian Noise with Hurst Parameters H ∈ (1/3, 1/2] [PDF]

open access: yesSIAM Journal on Applied Dynamical Systems, 2015
We consider the stochastic evolution equation $du=Audt+G(u)d\omega,\quad u(0)=u_0$ in a separable Hilbert space $V$. Here $G$ is supposed to be three times Frechet-differentiable and $\omega$ is a trace class fractional Brownian motion with Hurst ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Extended Differential Balancing for Nonlinear Dynamical Systems

open access: yesIEEE Control Systems Letters, 2022
In this paper, we construct extended balancing theory for nonlinear systems in the contraction framework. At first, we introduce the concept of the extended differential observability Gramian and inverse of the extended differential controllability Gramian for nonlinear dynamical systems and show their correspondence with generalized differential ...
