Stability analysis and stabilization for singular systems with multiple time-varying delay

open access: yes, 2010
This paper considers the problem associated with the stability analysis and stabilization for singular systems with multiple time-varying delays. The delay-dependent stability criterion and the method of designing state feedback stabilization controller ...

Investigation of a Generalized Frequency Domain Method for Modeling Time-Varying Loads on Antennas [PDF]

open access: yes, 2019
Within traditional antenna design, the behavior of the antenna can be dictated by its physical dimensions and their proportions to a wavelength. Traditional electrically small antennas in particular face many limitations on factors such as their gain ...

Neural Coding and Feature Extraction of Time-Varying Signals [PDF]

open access: yes, 2002
What are the neuronal codes that the brain uses to represent information? This constitutes one of the most fascinating and challenging questions in Neuroscience.

Policy iteration for H∞ control of polynomial time‐varying systems

open access: yesIET Control Theory & Applications
This paper studies the H∞ control problem for polynomial time‐varying systems. The H∞ control problem has been much less investigated for time‐varying systems in comparison to the time‐invariant systems.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Synchronization of Fractional Chaotic Systems with Time-Varying Perturbation

open access: yesFractal and Fractional
Aiming at the synchronization problem of fractional time-varying perturbation systems, an improved WRBF neural network was proposed based on the wavelet function and radial basis function (RBF).

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Expected optimal feedback with Time-Varying Parameters [PDF]

open access: yes
In this paper we derive, by using dynamic programming, the closed loop form of the Expected Optimal Feedback rule with time varying parameter. As such this paper extends the work of Kendrick (1981, 2002, Chapter 6) for the time varying parameter case ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
