Synchronization in cilia carpets: multiple metachronal waves are stable, but one wave dominates [PDF]
New Journal of Physics, 2022 Abstract Carpets of actively bending cilia represent arrays of biological oscillators that can exhibit self-organized metachronal synchronization in the form of traveling waves of cilia phase. This metachronal coordination supposedly enhances fluid transport by cilia carpets.

Robust formation of metachronal waves in directional chains of phase oscillators [PDF]
Physical 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 ...

Designing metachronal waves of cilia [PDF]
arXiv, 2020 On surfaces with many motile cilia, beats of the individual cilia coordinate to form metachronal waves. We present a theoretical framework that connects the dynamics of an individual cilium to the collective dynamics of a ciliary carpet via systematic coarse-graining.

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

Transport efficiency of metachronal waves in 3D cilium arrays immersed in a two-phase flow [PDF]
Journal of Fluid Mechanics, 2017 This work reports the formation and characterization of antipleptic and symplectic metachronal waves in 3D cilium arrays immersed in a two-fluid environment, with a viscosity ratio of 20. A coupled lattice Boltzmann–immersed-boundary solver is used. The periciliary layer is confined between the epithelial surface and the mucus.

Fluid circulation driven by collectively organized metachronal waves in swimming T. aceti nematodes [PDF]
Physical Review E, 2022 Recent experiments have shown that the nematode {\it T. aceti} can assemble into collectively undulating groups at the edge of fluid drops. This coordinated state consists of metachronal waves and drives fluid circulation inside the drop. We find that the circulation velocity is about 2 mm/s and nearly half the speed of the metachronal wave. We develop

Direction selection of metachronal waves in hydrodynamic coordination of cilia [PDF]
arXiv, 2023 Large arrays of active cilia coordinate their beat cycles into metachronal waves. These waves can travel in different directions with respect to the cilium's beat direction and the resulting direction of fluid propulsion. Hydrodynamic interactions provide a mechanism for the individual cilia to coordinate their beat cycles.

Role of cilia activity and surrounding viscous fluid in properties of metachronal waves
Physical Review E, 2023 Large groups of active cilia collectively beat in a fluid medium as metachronal waves, essential for some microorganisms motility and for flow generation in mucociliary clearance. Several models can predict the emergence of metachronal waves, but what controls the properties of metachronal waves is still unclear.

Metachronal waves in magnetic micro-robotic paddles for artificial cilia [PDF]
Communications Materials, 2021 AbstractBiological cilia generate fluid movement within viscosity-dominated environments using beating motions that break time-reversal symmetry. This creates a metachronal wave, which enhances flow efficiency. Artificially mimicking this behaviour could improve microfluidic point-of-care devices, since viscosity-dominated fluid dynamics impede fluid ...
