Journal ArticleDOI
Ant groups optimally amplify the effect of transiently informed individuals
TL;DR: The theoretical models predict that the ant-load system can be transitioned through the critical point of this mesoscopic system by varying its size; the findings show that efficient group-level processes can arise from transient amplification of individual-based knowledge.
Journal ArticleDOI
Dynamics of Active Semiflexible Polymers
Abhijit Ghosh,Nir S. Gov +1 more
TL;DR: It is proposed that the interplay between elasticity and activity is driving long-range correlations in the model system, and may also be manifest inside living cells.
Journal ArticleDOI
Euler buckling-induced folding and rotation of red blood cells in an optical trap
Abhijit Ghosh,Abhijit Ghosh,Supurna Sinha,Supurna Sinha,Jayashree A. Dharmadhikari,Sanjukta Roy,Aditya K. Dharmadhikari,Joseph Samuel,Joseph Samuel,Shobhona Sharma,Deepak Mathur +10 more
TL;DR: A model based on geometric considerations, using the concept of buckling instabilities, captures the folding phenomenon; the rotation of the cell is rationalized using the Poincaré sphere and a possible mechanism for the emergence of birefringent properties in the RBC in the folded state is suggested.
Journal ArticleDOI
A “Gaussian” for diffusion on the sphere
TL;DR: In this paper, an analytical closed form expression for diffusion on a sphere is presented. But the analytical formula is derived using saddle point methods for short times, and it works well even for intermediate times.
Journal ArticleDOI
Thermal breakage and self-healing of a polymer chain under tensile stress.
TL;DR: Comparison with simulation data in one and three dimensions demonstrates that the Kramers-Langer theory provides good qualitative description of the process of bond scission as caused by a collective unstable mode.
