Asymptotic behavior of eigenvalues of large rank perturbations of large random matrices

Ievgenii Afanasiev, Leonid Berlyand, Mariia Kiyashko

The paper is concerned with deformed Wigner random matrices. These matrices are closely related to Deep Neural Networks (DNNs): weight matrices of trained DNNs could be represented…

Bifurcation of finger-like structures in traveling waves of epithelial tissues spreading

Leonid Berlyand, Antonina Rybalko, Volodymyr Rybalko +1

We consider a continuum active polar fluid model for the spreading of epithelial monolayers introduced by R. Alert, C. Blanch-Mercader, and J. Casademunt, 2019. The corresponding f…

Dynamics and steady state of squirmer motion in liquid crystal

Leonid Berlyand, Hai Chi, Mykhailo Potomkin +1

We analyze a nonlinear PDE system describing the motion of a microswimmer in a nematic liquid crystal environment. For the microswimmer's motility, the squirmer model is used in wh…

A novel multi-scale loss function for classification problems in machine learning

Leonid Berlyand, Robert Creese, Pierre-Emmanuel Jabin

We introduce two-scale loss functions for use in various gradient descent algorithms applied to classification problems via deep neural networks. This new method is generic in the…

Emergence of traveling waves and their stability in a free boundary model of cell motility

Volodymyr Rybalko, Leonid Berlyand

We introduce a two-dimensional Hele-Shaw type free boundary model for motility of eukaryotic cells on substrates. The key ingredients of this model are the Darcy law for overdamped…

Stability of Contraction-Driven Cell Motion

C. Alex Safsten, Volodymyr Rybalko, Leonid Berlyand

We consider motility of keratocyte cells driven by myosin contraction and introduce a 2D free boundary model for such motion. This model generalizes a 1D model from [12] by combini…
