Active modulation of surfactant driven flow instabilities by swarming bacteria
Harshitha S. Kotian, Shalini Harkar, Shubham Joge +4
Models based on surfactant driven instabilities have been employed to describe pattern formation by swarming bacteria. However, by definition, such models cannot account for the ef…
Tuning the torque-speed characteristics of bacterial flagellar motor to enhance the swimming speed
Praneet Prakash, Amith Z. Abdulla, Varsha Singh +1
In a classic paper, Edward Purcell analysed the dynamics of flagellated bacterial swimmers and derived a geometrical relationship which optimizes the propulsion efficiency. Experim…
A Null-model Exhibiting Synchronized Dynamics in Uncoupled Oscillators
Tuhin Chakrabortty, Akash Suman, Anjali Gupta +2
The phenomenon of phase synchronization of oscillatory systems arising out of feedback coupling is ubiquitous across physics and biology. In noisy, complex systems, one generally o…
Spatial Awareness of a Bacterial Swarm
Harshitha S. Kotian, Shalini Harkar, Shubham Joge +4
Bacteria are perhaps the simplest living systems capable of complex behaviour involving sensing and coherent, collective behaviour an example of which is the phenomena of swarming…
