A geometry-dependent, force balance-driven model of Staphylococcus epidermidis biofilm cell cluster detachment
Yuehui Xu, Jasmine A. F. Kreig, Zhuoran Wang +3
Biofilms, bacteria cells surrounded by a self-produced polymeric matrix, are common on medical devices and lead to many hospital infections. The biofilm lifecycle includes disassem…
Analysis of the stability of an immersed elastic surface using the method of regularized Stokeslets
Dana Ferranti, Sarah D. Olson
A linear stability analysis of an elastic surface immersed in a viscous fluid is presented. The coupled system is modeled using the method of regularized Stokeslets (MRS), a Lagran…
Bayesian uncertainty quantification for micro-swimmers with fully resolved hydrodynamics
Karen Larson, Sarah Olson, Anastasios Matzavinos
Due to the computational complexity of micro-swimmer models with fully resolved hydrodynamics, parameter estimation has been prohibitively expensive. Here, we describe a Bayesian u…
Computational framework to capture the spatiotemporal density of cells with a cumulative environmental coupling
Michael A. Yereniuk, Sarah D. Olson
Stochastic agent-based models can account for millions of cells with spatiotemporal movement that can be a function of different factors. However, these simulations can be computat…
A hybrid cellular automaton model of cartilage regeneration capturing the interactions between cellular dynamics and scaffold porosity
Simone Cassani, Sarah D. Olson
To accelerate the development of strategies for cartilage tissue engineering, models are necessary to study the interactions between cellular dynamics and scaffold (SC) porosity. I…
Global Density Analysis for an Off-Lattice Agent-Based Model
Michael A. Yereniuk, Sarah D. Olson
Agent-based (AB) or Cellular Automata (CA) models are rule based and are a relatively simple discrete method that can be used to simulate complex interactions of many agents or cel…
A 3-dimensional model of flagellar swimming in a Brinkman fluid
Nguyenho Ho, Karin Leiderman, Sarah Olson
We investigate 3-dimensional flagellar swimming in a fluid with a sparse network of stationary obstacles or fibers. The Brinkman equation is used to model the average fluid flow wh…
Emergent three-dimensional sperm motility: Coupling calcium dynamics and preferred curvature in a Kirchhoff rod model
Lucia Carichino, Sarah D. Olson
Changes in calcium concentration along the sperm flagellum regulate sperm motility and hyperactivation, characterized by an increased flagellar bend amplitude and beat asymmetry, e…
Accelerating the Uzawa Algorithm
Nguyenho Ho, Sarah D. Olson, Homer F. Walker
The Uzawa algorithm is an iterative method for the solution of saddle-point problems, which arise in many applications, including fluid dynamics. Viewing the Uzawa algorithm as a f…
Swimming Speeds of Waving Cylindrical Tails in Viscous Fluids with Resistance
Nguyenho Ho, Karin Leiderman, Sarah D. Olson
Many microorganisms swim in a highly heterogeneous environment with obstacles such as fibers or polymers. To better understand how this environment affects microorganism swimming,…
Radial Basis Function (RBF)-based Parametric Models for Closed and Open Curves within the Method of Regularized Stokeslets
Varun Shankar, Sarah D. Olson
The method of regularized Stokeslets (MRS) is a numerical approach using regularized fundamental solutions to compute the flow due to an object in a viscous fluid where inertial ef…
