Size-structured populations with growth fluctuations: Feynman--Kac formula and decoupling
Ethan Levien, Yaïr Hein, Farshid Jafarpour
We study a size-structured population model in which individual cells grow at a rate determined by a fluctuating internal variable (e.g., gene expression levels). Many previous mod…

Competition between transient oscillations and early stochasticity in exponentially growing populations
Yaïr Hein, Farshid Jafarpour
It has been recently shown that the exponential growth rate of a population of bacterial cells starting from a single cell shows transient oscillations due to early synchronized bu…
