Variational Dimension Lifting for Robust Tracking of Nonlinear Stochastic Dynamics
Yonatan L. Ashenafi
Nonlinear stochastic motion presents significant challenges for Bayesian particle tracking. To address this challenge, we propose a lifting framework that constructs a higher-dimen…

Stochastic Analysis of Taxis and Kinesis Properties of Colonial Protozoa
Yonatan L. Ashenafi, Peter R. Kramer
Protozoan colonies undergo stimulus driven motion for purposes such as nutrient acquisition. Colonial response to a stimulus is mediated through a mechanical aggregation of the res…

Statistical Mobility of Multicellular Colonies of Flagellated Swimming Cells
Yonatan Ashenafi, Peter R. Kramer
We study the stochastic hydrodynamics of colonies of flagellated swimming cells, typified by multicellular choanoflagellates, which can form both rosette and chainlike shapes. The…
