Electronic Journal of Differential Equations, 2017 We show that any germ of smooth hyperbolic diffeomophism at a fixed point is conjugate to its linear part, using a transformation with a Mourtada type functions, which (roughly) means that it may contain terms like $x \log |x|$.

Control of Rotary Inverted Pendulum Using Model-Free Backstepping Technique
IEEE Access, 2019 This paper presents control studies of a rotary inverted pendulum (RIP) by applying a model-free backstepping (MFBS) control technique. We first discuss the new MFBS technique, which does not rely on the detailed model of the system, and makes use of ...

FEBS 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 ...

Local Dynamics of an Equation with Large Exponential Distributed Delay
Моделирование и анализ информационных систем, 2011 We study properties of local dynamics of a differential equation with exponentially distributed delay. In critical cases we built special evolutionary equations.

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Stability and Hopf bifurcation in a symmetric Lotka-Volterra predator-prey system with delays
Electronic Journal of Differential Equations, 2013 This article concerns a symmetrical Lotka-Volterra predator-prey system with delays. By analyzing the associated characteristic equation of the original system at the positive equilibrium and choosing the delay as the bifurcation parameter, the local ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Normal form transforms separate slow and fast modes in stochastic dynamical systems [PDF]
, 2008 © 2007 Elsevier B.V. All rights reserved.Modelling stochastic systems has many important applications. Normal form coordinate transforms are a powerful way to untangle interesting long term macroscale dynamics from insignificant detailed microscale ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
