Summary

Active filament bundles exhibit solitary wave propagation due to contractions and sliding. Binding to a substrate enables self-organized net motion, revealing complex dynamic behaviors in these systems.

Active bundles of polar and bipolar filaments.

Physical review. E·2018

Area of Science:

  • Physics, Biophysics
  • Materials Science

Background:

  • Bundles of polar filaments interacting via active elements display complex dynamics.
  • Understanding these dynamics is crucial for various biological and engineered systems.

Purpose of the Study:

  • To develop a general description for bundle dynamics.
  • To identify conditions leading to solitary wave propagation.
  • To investigate self-organized motion through substrate interactions.

Main Methods:

  • A simplified, general model for bundle dynamics was employed.
  • Analysis focused on density profiles and solitary wave characteristics.
  • Filament binding and detachment dynamics were incorporated.

Main Results:

  • Regimes were identified where density profiles propagate as solitary waves with characteristic velocities.
  • These solitary waves arise from local contractions and relative sliding of filaments.
  • Filament binding/detachment from a substrate generates net system motion.

Conclusions:

  • The study provides a general framework for understanding active filament bundle dynamics.
  • Solitary wave propagation is a key emergent behavior.
  • Self-organization through substrate interaction offers a mechanism for directed motion.
