The structural relaxation time of a polymer glass during deformation
Pradip K. Bera, Grigori A. Medvedev, James M. Caruthers +1
In order to determine the structural relaxation time of a polymer glass during deformation, a strain rate switching experiment is performed in the steady-state plastic flow regime.…
Shape-Independent Fluidity in Epithelial Cell Monolayers
Pradip K. Bera, Anh Q. Nguyen, Molly McCord +2
Tissue fluidity regulates biological processes such as embryonic development, wound healing, and cancer metastasis. In confluent epithelia, where cell packing fraction is effective…
Cell-Cell Adhesion as a Double-Edged Sword in Tissue Fluidity
Anh Q. Nguyen, Pradip K. Bera, Jacob Notbohm +1
Cell migration plays a fundamental role in numerous physiological processes, including embryonic development, wound healing, and cancer metastasis. While cell-cell adhesion is know…
Instability and stress fluctuations of a probe driven through a worm-like micellar fluid
Abhishek Ghadai, Pradip Kumar Bera, Sayantan Majumdar
A particle moving through a worm-like micellar fluid (WLM) shows instability and large fluctuations beyond a threshold \textcolor{black}{velocity/force (depending on the control pa…
Traction and Stress Control Formation and Motion of +1/2 Topological Defects in Epithelial Cell Monolayers
Pradip K. Bera, Molly McCord, Jun Zhang +1
In confluent cell monolayers, patterns of cell forces and motion are systematically altered near topological defects in cell shape. In turn, defects have been proposed to alter cel…
