Kinematics and directionality of body turning in water striders (Gerris argentatus) on the water surface

Insect Science, EarlyView.
This graphical abstract illustrates the kinematics and directionality of body turning in water striders (Gerris argentatus). The top image shows a water strider making turns, with arrows indicating possible directions and a dashed line tracing its path, highlighting its dynamic turning capabilities.

Expanding the Ichnofacies Model to Tidal Straits: Testing Predictions and Assessing Anomalies

Terra Nova, EarlyView.
ABSTRACT Trace fossils are instrumental in facies analysis, but some depositional environments remain underexplored. Cenozoic deposits in Italy have been studied to evaluate the ichnology of tidal straits. These comprise four zones: (1) strait centre, (2) dune‐bedded strait zone, (3) strait end and (4) strait margin.

Optimization of Thermally Radiative and Mass Wavy Flow Analysis Affected by Induced Magnetic Field and Joule Heating

Energy Science &Engineering, Volume 13, Issue 10, Page 4917-4932, October 2025.
ABSTRACT The role of magnetic induction is declared fundamental in many technological systems, including electric generators, inductors, transformers, and so on. This is an important source for converting energy from one form to another while utilizing electromagnetic induction. This phenomenon is efficient when the induced magnetic field is introduced

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.

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 ...
