Link updating strategies influence consensus decisions as a function of the direction of communication
Sharaj Kunjar, Ariana Strandburg-Peshkin, Helge Giese +4
Consensus decision-making in social groups strongly depends on communication links that determine to whom individuals send, and from whom they receive, information. Here, we ask ho…
Efficacy of information transmission in cellular communication
Sumantra Sarkar, Sandeep Choubey
Inter and intra-cellular signaling are essential for individual cells to execute various physiological tasks and accurately respond to changes in their environment. Signaling is ca…
Concentration dependence of diffusion-limited reaction rates and its consequences
Sumantra Sarkar
Diffusion-limited association reactions are ubiquitous in nature. They are particularly important for biological reactions, where the reaction rates are often determined by the dif…
Design of conditions for emergence of self-replicators
Sumantra Sarkar, Jeremy L. England
A self-replicator is usually understood to be an object of definite form that promotes the conversion of materials in its environment into a nearly identical copy of itself. The ch…
Shear-induced organization of forces in dense suspensions: signatures of discontinuous shear thickening
Sumantra Sarkar, Elan Shatoff, Kabir Ramola +3
Dense suspensions can exhibit an abrupt change in their viscosity in response to increasing shear rate. The origin of this discontinuous shear thickening (DST) has been ascribed to…
Shear-induced rigidity of frictional particles: Analysis of emergent order in stress space
Sumantra Sarkar, Dapeng Bi, Jie Zhang +3
Solids are distinguished from fluids by their ability to resist shear. In traditional solids, the resistance to shear is associated with the emergence of broken translational symme…
Shear induced rigidity in athermal materials: a unified statistical framework
Sumantra Sarkar, Bulbul Chakraborty
Recent studies of athermal systems such as dry grains and dense, non-Brownian suspensions have shown that shear can lead to solidification through the process of shear jamming in g…
Origin of Rigidity in Dry Granular Solids
Sumantra Sarkar, Dapeng Bi, Jie Zhang +2
Solids are distinguished from fluids by their ability to resist shear. In traditional solids, the resistance to shear is associated with the emergence of broken translational symme…
Broad-tailed force distributions and velocity ordering in a heterogeneous membrane model for collective cell migration
Tripti Bameta, Dipjyoti Das, Sumantra Sarkar +2
Correlated velocity patterns and associated large length-scale transmission of traction forces have been observed in collective live cell migration as a response to a "wound". We a…
