Electrical oscillations in microtubules

This study introduces a multi-scale electrokinetic model to characterize electrical impulses and ionic current propagation along microtubules, incorporating atomistic protein details and biological environments. It emphasizes nanopore-mediated coupling between microtubule surfaces as a key mechanism enabling luminal…

Investigation of electric field enhancement between metal blocks at the focused field generated by a radially polarized beam.

This engineering/optics study examines focusing properties of a radially polarized beam interacting with gold metal cubes arranged along the beam propagation direction. It reports >20d7 electric field enhancement between two cubes separated by bb/10 on the optical axis, linked to a strong longitudinal field and…

Advancing profiling sensors with a wireless approach.

This engineering paper describes a wireless implementation of a near-infrared profiling sensor using multiple sensor nodes and a base station for data preprocessing and realignment. It reports an enhanced classification approach using a back-propagation neural network to categorize objects as human, animal, or…

Ultrasonic propagation velocity in magnetic and magnetorheological fluids due to an external magnetic field.

This engineering-focused study measured ultrasonic propagation velocity in hydrocarbon-based magnetic and magnetorheological fluids under an external magnetic field. The authors report that clustering structures formed in the fluids influence ultrasonic propagation velocity, with observed hysteresis and anisotropy.…
