Metachronal waves in concentrations of swimming Turbatrix aceti nematodes and an oscillator chain model for their coordinated motions [PDF]

Physical Review E, 2021
At high concentration, free swimming nematodes known as vinegar eels (Turbatrix aceti), collectively exhibit metachronal waves near a boundary. We find that the frequency of the collective traveling wave is lower than that of the freely swimming ...

Longitudinal to Transverse Metachronal Wave Transitions in an In Vitro Model of Ciliated Bronchial Epithelium [PDF]

Physical Review Letters, 2022
Myriads of cilia beat on ciliated epithelia, which are ubiquitous in life. When ciliary beats are synchronized, metachronal waves emerge, whose direction of propagation depends on the living system in an unexplained way. We show on a reconstructed human bronchial epithelium in-vitro that the direction of propagation is determined by the ability of ...

Metachronal waves for deterministic switching two-state oscillators with hydrodynamic interaction [PDF]

Physical Review E, 2003
We employ a model system, called rowers, as a generic physical framework to define the problem of the coordinated motion of cilia (the metachronal wave) as a far from equilibrium process. Rowers are active (two-state) oscillators in a low Reynolds number fluid, and interact solely through the forces of hydrodynamic origin. In this work, we consider the

Bilateral Asymmetry shown by the Metachronal Waves in Protochordate Gill Slits [PDF]

Nature, 1949
MULLER1 stated that metachronal waves travelled round the gill slits of Amphioxus "am vordern Rande aufwarts, am hinten abwarts" ; but he figured them moving in the opposite direction on the left side of the pharynx. Franz2 did not clear up the contradiction, though he, too, noted and figured the metachronal waves.

Exploring entropy production in metachronal wave motion of Carreau fluid in a channel under lubrication hypothesis

International Journal of Thermofluids
The energy loss associated with the beating of cilia in the human stomach, leading to acidity in the blood flow under certain conditions, has become a critical topic in modern medical research.

Fallopian tube rheology regulates epithelial cell differentiation and function to enhance cilia formation and coordination [PDF]

Nature Communications
The rheological properties of the extracellular fluid in the female reproductive tract vary spatiotemporally, however, the effect on the behaviour of epithelial cells that line the tract is unexplored. Here, we reveal that epithelial cells respond to the

Entropic analysis of cilia-modulated slip flow of trimetallic nanofluid through electroosmotic corrugated pump in the presence of inclined magnetic field [PDF]

Scientific Reports, 2023
An incredible eradication of thermal indulgence is required to enhance the flow and heat transfer enhancement in micro/nanofluidic devices. In addition, the rapid transport and instantaneous mixing of colloidal suspensions of metallic particles at ...

Non-Newtonian fluid model analysis due to metachronal waves of cilia: A physiological mathematical model

Partial Differential Equations in Applied Mathematics
The Phan–Thien–Tanner non-Newtonian model of fluid flow is considered to mathematically model the cilia governed flow inside human body. The collective action of cilia generates a rhythmic motion in form of metachronal wave travelling along the wall of ...

Measurement of thermal radiative and mass transfer of peristaltic pumping of electrically-conducting bio-bi-phase flow due to metachronal wave: Eukaryotic cells in biological applications

Case Studies in Thermal Engineering, 2023
Cilia motion are commonly located in mammalian cells of living organisms which is continually grow and feature conspicuously. The ciliary apparatus is associated to cell cycle movement and proliferation, and cilia show a dynamic part in human and animal ...
