Metachronal wave formation in a model of pulmonary cilia [PDF]

open access: yesComputers & Structures, 2007
A three-dimensional simulation of the formation of metachronal waves in rows of pulmonary cilia is presented. The cilia move in a two-layer fluid model. The fluid layer adjacent to the cilia bases is purely viscous while the tips of the cilia move through a viscoelastic fluid.

Cilia and electroosmosis induced double diffusive transport of hybrid nanofluids through microchannel and entropy analysis

open access: yesNonlinear Engineering, 2023
A mathematical model is presented to analyze the double diffusive transport of hybrid nanofluids in microchannel. The hybrid nanofluids flow is driven by the cilia beating and electroosmosis in the presence of radiation effects and activation energy.

EMHD creeping rheology of nanofluid through a micro-channel via ciliated propulsion under porosity and thermal effects

open access: yesCase Studies in Thermal Engineering, 2022
The mathematical study is modeled to examine the physical impacts of porosity and thermal slip on flow features of nanofluid through an asymmetric micro-channel. Additionally, the effects of electro-osmosis and magnetic field are also under consideration.

Entropy analysis in ciliary transport of radiated hybrid nanofluid in presence of electromagnetohydrodynamics and activation energy

open access: yesCase Studies in Thermal Engineering, 2021
The entropy of hybrid nanofluids flow driven by cilia beating is examined theoretically in this study. To control the cilia induced transport, electroosmosis and magnetohydrodynamics are introduced in the model.

Paramecium, a Model to Study Ciliary Beating and Ciliogenesis: Insights From Cutting-Edge Approaches

open access: yesFrontiers in Cell and Developmental Biology, 2022
Cilia are ubiquitous and highly conserved extensions that endow the cell with motility and sensory functions. They were present in the first eukaryotes and conserved throughout evolution (Carvalho-Santos et al., 2011).

Interpreting the synchronisation of driven colloidal oscillators via the mean pair interaction

open access: yesNew Journal of Physics, 2018
To explore the generic features of synchronisation facilitated by hydrodynamic interactions dominated by viscous forces, we investigate small systems of rowers; rowers are a highly simplified model for motile cilia, with each cilium approximated by a ...

Robust formation of metachronal waves in directional chains of phase oscillators

open access: yesPhysical Review E, 2023
Biological systems can rely on collective formation of a metachronal wave in an ensemble of oscillators for locomotion and for fluid transport. We consider one-dimensional chains of phase oscillators with nearest neighbor interactions, connected in a loop and with rotational symmetry, so each oscillator resembles every other oscillator in the chain ...

Metachronal Waves in Cellular Automata: Cilia-Like Manipulation in Actuator Arrays [PDF]

open access: yes, 2014
Paramecium is covered by cilia. It uses the cilia to swim and transport food particles to its mouth. The cilia are synchronised into a collective action by propagating membrane potential and mechanical properties of their underlying membrane and the liquid phase environment.
