Reprogrammable Magnetically Actuated Self‐Assembled Cilia Array

open access: yesAdvanced Intelligent Systems, 2023
Motile cilia move in an asymmetric pattern and implement a metachronal wave (MCW) to facilitate fluid movement in a viscous environment. Studies have been conducted to mimic MCW movement of motile cilia, but the fabrication process is too complicating or

Mathematical Modeling of Mucociliary Clearance: A Mini-Review

open access: yesCells, 2019
Mucociliary clearance is an important innate host defense of the mammalian respiratory system, as it traps foreign substances, including pollutants, pathogens, and allergens, and transports them out of the airway.

Fractional Burgers Fluid Flow Due to Metachronal Ciliary Motion in an Inclined Tube

open access: yesFrontiers in Physiology, 2019
Cilia-induced flow of fractional Burgers fluid is studied in an inclined tube for both symplectic and antiplectic wave patterns. The solution of the problem is persued under the long wave length limitation.

Concentration and Thermal Analysis of immiscible Tangent hyperbolic fluid with distinct viscosity through horizontal asymmetric channel: Theoretical and Observational study

open access: yesCase Studies in Thermal Engineering, 2023
This study examines cilia induced Tangent hyperbolic fluid flow with distinct viscosity, density in addition to thermal conductivity through horizontal asymmetric channel in two adjacent layers. The impact of mass and heat transfer in two adjacent layers

Cilia-assisted hydromagnetic pumping of biorheological couple stress fluids

open access: yesPropulsion and Power Research, 2019
A theoretical study is conducted for magnetohydrodynamic pumping of electro-conductive couple stress physiological liquids (e.g. blood) through a two-dimensional ciliated channel. A geometric model is employed for the cilia which are distributed at equal

Pathogenesis of chronic rhinosinusitis with nasal polyps: role of IL-6 in airway epithelial cell dysfunction

open access: yesJournal of Translational Medicine, 2020
Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by an alteration in airway epithelial cell functions including barrier function, wound repair mechanisms, mucociliary clearance.

Cilium height difference between strokes is more effective in driving fluid transport in mucociliary clearance: A numerical study

open access: yesMathematical Biosciences and Engineering, 2015
Mucociliary clearance is the first line of defense in our airway. The purpose of this study is to identify and study key factors in the cilia motion that influence the transport ability of the mucociliary system.

A codimension-2 bifurcation controlling endogenous bursting activity and pulse-triggered responses of a neuron model. [PDF]

open access: yesPLoS ONE, 2014
The dynamics of individual neurons are crucial for producing functional activity in neuronal networks. An open question is how temporal characteristics can be controlled in bursting activity and in transient neuronal responses to synaptic input ...

Spontaneous Synchronization of Beating Cilia: An Experimental Proof Using Vision-Based Control

open access: yesFluids, 2018
This article investigates the formation of spontaneous coordination in a row of flexible 2D flaps (artificial cilia) in a chamber filled with a high viscous liquid (Re = 0.12). Each flap is driven individually to oscillate by a rotary motor with the root

Trapping study of nanofluids in an annulus with cilia

open access: yesAIP Advances, 2015
The main purpose of this article is to present a mathematical model of ciliary motion in an annulus. In this analysis, two dimensional flow of a viscous nanofluid is observed in an annulus with ciliated tips. The current theoretical model may be supposed
