Title: Kinetic Monte Carlo Simulations of Multicellular Aggregate Self-Assembly in Biofabrication Abstract:  We present a three-dimensional lattice model to study self-assembly and fusion of multicellular aggregate systems by using kinetic Monte Carlo (KMC) simulations. This model is developed to describe and predict the time evolution of postprinting morphological structure formation during tissue or organ maturation in

Title: Variations of the sharp interfaces in multiphase problems - Part IV Abstract: In the first part of the talk, we will show the existence of a minimizer for a minimal surface problem with prescribed mean curvature and obstacle.  In the second part, we will focus on the question whether the minimizing surface enjoys enough

Title: Variations of the sharp interfaces in multiphase problems - Part V Abstract: We will conitnue with the discussion on the regularity of a minimal surface with prescribed mean curvature and obstacle. The problem leads to a variational inequality. Then we will use a result by Breiz and Kinderlehrer to show that the minimizing surface

TITLE: Deformable inclusion jamming for improved magnetorheological performance Abstract: Magnetorheological fluids (MRFs) are simple systems of magnetic particles dispersed in a non-magnetic carrier fluid.  When a magnetic field is applied to the MRF, magnetic particles form chains and the fluid becomes more solid-like and able to resist shear forces.  This liquid to solid transition, which

Title: Regularization methods for the Poisson-Boltzmann model with sharp or diffuse interfaces Abstract: Both the sharp interface and diffuse interface Poisson-Boltzmann (PB) models have been presented in the literature for studying electrostatic interactions between a solute molecule and its surrounding solvent environment. In the mathematical analysis and numerical computation for these PB models, a significant

TITLE: Revealing the mechanisms of molecular motors’ motility by using computational approaches ABSTRACT: Dynein is a molecular motor for cargo transportation and force generation in cells. Dysfunction of dynein is associated with many diseases, such as ciliopathies, lissencephaly and other neurodegeneration disorders. Understanding the functions of dynein is crucial for developing new treatments of such

Title: Pearling and Localized Undulation of Bilayers in Amphiphilic Morphology Abstract: Amphiphiles, such as lipids and functionalized polymers, plays a central role in the self-assembly of solvent accessible, intricately structured nano-scaled network structures, which are vital in cell functionality and offer wide applications to drug delivery, detergent production, emulsion stabilization and energy conversion devices. We
