The minimal intrinsic stochasticity of constitutively expressed eukaryotic genes is sub-Poissonian
Gene expression inherently gives rise to stochastic variation (“noise”) in the production of
gene products. Minimizing noise is crucial for ensuring reliable cellular functions. However …

Joint distribution of protein concentration and cell volume coupled by feedback in dilution
We consider a protein that negatively regulates the rate with which a cell grows. Since less
growth means less protein dilution, this mechanism forms a positive feedback loop on the …
