Role of cilia activity and surrounding viscous fluid in properties of metachronal waves

Physical Review E
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.

Magnetic Reprogramming of Self‐Assembled Hard‐Magnetic Cilia

Advanced Materials Technologies, Volume 9, Issue 13, July 8, 2024.
Hard‐magnetic cilia form through self‐assembly of NdFeB microparticles within a thermoplastic polyurethane elastomer. NdFeB cilia can be remagnetized, which reprograms their actuation behaviors. Performing demagnetization prior to remagnetization improves the reprogrammability of the cilia.

Bifurcation Analysis and Spatiotemporal Patterns of Nonlinear Oscillations in a Ring Lattice of Identical Neurons with Delayed Coupling

Abstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014
We investigate the dynamics of a delayed neural network model consisting of n identical neurons. We first analyze stability of the zero solution and then study the effect of time delay on the dynamics of the system. We also investigate the steady state bifurcations and their stability.

Walking Behavior Observed in Phoxichilidium femoratum (Rathke, 1799) and Nymphon brevirostre Hodge 1863 Collected from Kandalaksha Bay of the White Sea, Russia

International Journal of Oceanography, Volume 2014, Issue 1, 2014., 2014
In this study, the walking behavior of Phoxichilidium femoratum and Nymphon brevirostre was investigated using video recordings. The walking behavior of P. femoratum while walking over the colonial hydroids that they normally feed on and on relatively smooth glass surfaces was observed. In the case of N.

Light‐Fueled Nonreciprocal Self‐Oscillators for Fluidic Transportation and Coupling

Advanced Materials, Volume 36, Issue 12, March 21, 2024.
Non‐equilibrium self‐sustained motions are widely reported in stimuli‐responsive material systems. Here, a cilia‐like soft actuator that can perform self‐sustained oscillation under water, with programmable nonreciprocal strokes, is demonstrated. The self‐oscillators can realize microfluidic pumping, translocation of a micro‐object, and coupling ...
