The impact of maturation time distributions on the structure and growth of cellular populations

open access: yesMathematical Biosciences and Engineering, 2020
Here we study how the structure and growth of a cellular population vary with the distribution of maturation times from each stage. We consider two cell cycle stages. The first represents early G1. The second includes late G1, S, G2, and mitosis. Passage

Characteristic of Bennett’s acceptance ratio method

open access: yesPhysical Review E, 2009
A powerful and well-established tool for free-energy estimation is Bennett's acceptance ratio method. Central properties of this estimator, which employs samples of work values of a forward and its time reversed process, are known: for given sets of measured work values, it results in the best estimate of the free-energy difference in the large sample ...

Manufacturing an Exact Solution for 2D Thermochemical Mantle Convection Models

open access: yesGeochemistry, Geophysics, Geosystems, 2023
In this study, we manufacture an exact solution for a set of 2D thermochemical mantle convection problems. The derivation begins with the specification of a stream function corresponding to a non‐stationary velocity field.
