Numerical Study of Metachronal Wave‐Modulated Locomotion in Magnetic Cilia Carpets [PDF]
Advanced Intelligent Systems, 2023 Metachronal motions are ubiquitous in terrestrial and aquatic organisms and have attracted substantial attention in engineering for their potential applications.

Synchronization in cilia carpets: multiple metachronal waves are stable, but one wave dominates [PDF]
New Journal of Physics, 2022 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.

Metachronal wave and hydrodynamic interaction for deterministic switching rowers [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 interacting solely through forces of hydrodynamic origin. In this work, we consider the case of fully deterministic dynamics,

Metachronal waves in a chain of rowers with hydrodynamic interactions [PDF]
arXiv, 2010 Filaments on the surface of a microorganism such as Paramecium or Ophalina beat highly synchronized and form so-called metachronal waves that travel along the surfaces. In order to study under what principal conditions these waves form, we introduce a chain of beads, called rowers, each periodically driven by an external force on a straight line ...

Metachronal waves in the flagellar beating of $Volvox$ and their hydrodynamic origin [PDF]
arXiv, 2015 Groups of eukaryotic cilia and flagella are capable of coordinating their beating over large scales, routinely exhibiting collective dynamics in the form of metachronal waves. The origin of this behaviour -- possibly influenced by both mechanical interactions and direct biological regulation -- is poorly understood, in large part due to lack of ...

Spontaneous creation of macroscopic flow and metachronal waves in an array of cilia [PDF]
Biophysical Journal, 2006 Cells or bacteria carrying cilia on their surface show many striking features : alignment of cilia in an array, two-phase asymmetric beating for each cilium, coordination between cilia and existence of metachronal waves with a constant phase difference between two adjacent cilia.

Robust formation of metachronal waves in directional chains of phase oscillators [PDF]
Physical Review E, 2022 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 wave formation in a model of pulmonary cilia. [PDF]
Comput Struct, 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.
