Proliferation-driven mechanical feedback regulates cell dynamics in growing tissues
Sumit Sinha, Xin Li, Abdul N Malmi-Kakkada +1
Local stresses in a tissue, a collective property, regulate cell division and apoptosis. In turn, cell growth and division induce active stresses in the tissue. As a consequence, t…
Noise in the direction of motion determines the spatial distribution and proliferation of migrating cell collectives
Jonathan E. Dawson, Abdul N. Malmi-Kakkada
A variety of living and non-living systems exhibit collective motion. From swarm robotics to bacterial swarms, and tissue wound healing to human crowds, examples of collective moti…
Enhanced mechanical heterogeneity of cell collectives due to temporal fluctuations in cell elasticity
Garrett Zills, Trinanjan Datta, Abdul N Malmi-Kakkada
Cells are dynamic systems characterized by temporal variations in biophysical properties such as stiffness and contractility. Recent studies show that the recruitment and release o…
Inter-particle adhesion regulates the surface roughness of growing dense three-dimensional active particle aggregates
Sumit Sinha, Abdul N Malmi-Kakkada
Activity and self-generated motion are fundamental features observed in many living and non-living systems. Given that inter-particle adhesive forces are known to regulate particle…
Dual Role of Cell-Cell Adhesion In Tumor Suppression and Proliferation Due to Collective Mechanosensing
Abdul Malmi-Kakkada, Xin Li, Sumit Sinha +1
It is known that mechanical interactions couple a cell to its neighbors, enabling a feedback loop to regulate tissue growth. However, the interplay between cell-cell adhesion stren…
Generalized Rayleigh-Plesset Theory for Cell Size Maintenance in Viruses and Bacteria
Abdul Malmi-Kakkada, D. Thirumalai
The envelopes covering bacterial cytoplasm possess remarkable elastic properties. They are rigid enough to resist large pressures while being flexible enough to adapt to growth und…
Cell growth rate dictates the onset of glass to fluid-like transition and long time super-diffusion in an evolving cell colony
Abdul N Malmi-Kakkada, Xin Li, Himadri S. Samanta +2
Collective migration dominates many phenomena, from cell movement in living systems to abiotic self-propelling particles. Focusing on the early stages of tumor evolution, we enunci…
Superfluid Field response to Edge dislocation motion
Abdul N. Malmi-Kakkada, Oriol T. Valls, Chandan Dasgupta
We study the dynamic response of a superfluid field to a moving edge dislocation line to which the field is minimally coupled. We use a dissipative Gross-Pitaevskii equation, and d…
Dislocation Mobility and Anomalous Shear Modulus Effect in He Crystals
Abdul N. Malmi-Kakkada, Oriol T. Valls, Chandan Dasgupta
We calculate the dislocation glide mobility in solid He within a model that assumes the existence of a superfluid field associated with dislocation lines. Prompted by the resul…
Ising Model on a random network with annealed or quenched disorder
Abdul N. Malmi-Kakkada, Oriol T. Valls, Chandan Dasgupta
We study the equilibrium properties of an Ising model on a disordered random network where the disorder can be quenched or annealed. The network consists of four-fold coordinated s…
Angular dependence of superconductivity in superconductor / spin valve heterostructures
Alejandro A. Jara, Christopher Safranski, Ilya N. Krivorotov +4
We report measurements of the superconducting transition temperature, , in CoO/Co/Cu/Co/Nb multilayers as a function of the angle between the magnetic moments of the Co la…
Hydrodynamics of compressible superfluids in confined geometries
Abdul N Malmi-Kakkada, Oriol T Valls, Chandan Dasgupta
We present a study of the hydrodynamics of compressible superfluids in confined geometries. We use a perturbative procedure in terms of the dimensionless expansion parameter $(v/v_…
