Fluid circulation driven by collectively organized metachronal waves in swimming T. aceiti 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

Fractional generalized Burgers’ fluid flow due to metachronal waves of cilia in an inclined tube [PDF]

Advances in Mechanical Engineering, 2017
In this study, the cilia-induced flow is discussed for fractional generalized Burgers’ fluid in an inclined tube. The mathematical model of fractional generalized Burgers’ fluid flow is obtained under the long-wavelength approximation.

Role of cilia activity and surrounding viscous fluid on properties of metachronal waves [PDF]

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 a chain of rowers with hydrodynamic interactions [PDF]

The European Physical Journal E, 2011
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 ...

Magnetically powered metachronal waves induce locomotion in self-assemblies [PDF]

Communications Physics, 2020
AbstractWhen tiny soft ferromagnetic particles are placed along a liquid interface and exposed to a vertical magnetic field, the balance between capillary attraction and magnetic repulsion leads to self-organization into well-defined patterns. Here, we demonstrate experimentally that precessing magnetic fields induce metachronal waves on the periphery ...

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.

Prominent fin-contributed swimming in squid (Loligo forbesii) supports efficient movement in seamount habitats [PDF]

Royal Society Open Science
Animal movements and the associated energy costs dictate an individual’s scope for activity and habitat use. Yet in situ measurements of movement often fail to quantify whole-body movement and their physiological costs. These challenges lead to data gaps

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 ...

Predicting the properties of metachronal waves from single-cilium characteristics

, 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.

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
