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 ...

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 ...

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

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.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

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 ...
