Statistical Mobility of Multicellular Colonies of Flagellated Swimming Cells

no code implementations20 Jul 2023 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.

Model Reduction of Linear Dynamical Systems via Balancing for Bayesian Inference

1 code implementation25 Nov 2021 Elizabeth Qian, Jemima M. Tabeart, Christopher Beattie, Serkan Gugercin, Jiahua Jiang, Peter R. Kramer, Akil Narayan

We introduce Gramian definitions relevant to the inference setting and propose a balanced truncation approach based on these inference Gramians that yield a reduced dynamical system that can be used to cheaply approximate the posterior mean and covariance.

no code implementations18 Nov 2019 Maria-Veronica Ciocanel, John Fricks, Peter R. Kramer, Scott A. McKinley

In many biological systems, the movement of individual agents is commonly characterized as having multiple qualitatively distinct behaviors that arise from various biophysical states.
