Koopman Spectral Linearization vs. Carleman Linearization: A Computational Comparison Study

Mathematics
Nonlinearity presents a significant challenge in developing quantum algorithms involving differential equations, prompting the exploration of various linearization techniques, including the well-known Carleman Linearization.

Myocellular adaptations to short‐term weighted wheel‐running exercise are largely conserved during C26‐tumour induction in male and female mice

Experimental Physiology, EarlyView.
Abstract This study investigated whether performing a translatable murine model of concurrent training after tumour induction affects adaptations in juvenile male and female tumour‐bearing mice. Male and female Balb/c mice were injected bilaterally with colon‐26 adenocarcinoma (C26) cells or PBS at 8 weeks of age.

Koopman fault‐tolerant model predictive control

IET Control Theory & Applications
This paper introduces a novel data‐driven approach to develop a fault‐tolerant model predictive controller (MPC) for non‐linear systems. By adopting a Koopman operator‐theoretic perspective, the proposed method leverages historical data from the system ...

Mathematical model of the zebrafish ventricular cardiomyocyte action potential and calcium transient

The Journal of Physiology, EarlyView.
Abstract figure legend This study presents the development and validation of the first biophysically detailed computational model of the zebrafish ventricular action potential (AP). The model is based on a human cardiomyocyte framework and reparameterized using published and newly generated patch‐clamp recordings of zebrafish ionic currents.

Non-autonomous Koopman operator family spectrum

, 2018
Poincar e at the beginning of XX-th century, and then Carleman, Koopman and von Neumann in the 1920-is made their visionary contributions to the analysis of dynamical systems behavior through the analysis of the spectral properties of the associated Koopman operator.

Optimality Deviation using the Koopman Operator

This paper investigates the impact of approximation error in data-driven optimal control problem of nonlinear systems while using the Koopman operator. While the Koopman operator enables a simplified representation of nonlinear dynamics through a lifted state space, the presence of approximation error inevitably leads to deviations in the computed ...

Validation of aerial photogrammetry methods to measure body size, condition and mass in small cetaceans

The Journal of Physiology, EarlyView.
Abstract figure legend Unoccupied aerial vehicle (UAV)‐based photogrammetry provides measurements equivalent to traditional hand measurements in bottlenose dolphins. Mass estimates derived from UAV measurements closely match the true body mass of live individuals.
