The Ag/Ag+ system: An impedance model for nucleation and growth

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1979
Abstract An analytical expression for the electrochemical impedance spectra is calculated, based on the assumption of successive monolayers generated at a mean nucleation rate and governed by the same ageing law. From simulated complex plane impedance plots, it is shown that this model can be applied to highly reversible metal-ion systems such as Ag +

A Numerical Method for Estimating the Variance of Age at Maximum Growth Rate in Growth Models [PDF]

Communications in Statistics - Theory and Methods, 2013
Studies on maturation and body composition mention age at peak height velocity (PHV) as an important measure that could predict adulthood outcome. The age at PHV is often derived from growth models such as the triple logistic fitted to the stature (height) data.

An age-structured model of epidermis growth

Journal of Mathematical Biology, 2010
We propose a model with age and space structure for the evolution of the supra-basal epidermis. The model includes different types of cells: proliferating cells, differentiated cells, corneous cells, and apoptotic cells. We assume that all cells move with the same velocity and that the local volume fraction, occupied by the cells is constant in space ...

Growth in age-structured stock assessment models

Fisheries Research, 2016
Abstract Growth – the way that fish get bigger as they get older – is one component of the population models used in fisheries stock assessments. I review current practice related to this component in age-structured models, discussing how growth is specified, its functions in the stock assessment model, and how growth-related data are used.

Age-dependent models of population growth

Theoretical Population Biology, 1984
P. H. Leslie (1945, Biometrika 33, 183-212) (and others) introduced vector-matrix growth difference equations to model populations in which birth and death rates are age-dependent. We develop differential versions of these equations in both the unrestricted growth and logistic cases.

On a multicompartment age-distribution model of cell growth

IMA Journal of Applied Mathematics, 2010
We study a linear multicompartment age-distribution model of cell growth, where the age variable represents the time spent in the current phase of cell growth. Our results are relevant for the modelling of cancer cells in vitro, where factors such as overcrowding and scarcity of nutrients (for which the model would have to be non-linear) can be ...

Age classification and growth model of Phrynocephalus przewalskii

Ecological Modelling, 1993
Abstract From April to September 1987, mark-recapture studies on Phrynocephalus przewalskii were conducted in a desert habitat of northwestern China. Captive lizards were coded using the toe-clipping method. Capture and recaptured lizards were measured according to body weight and snout-vent lenght. Growth pattern was obtained.
