Extending the hyper‐logistic model to the random setting: New theoretical results with real‐world applications

Mathematical Methods in the Applied Sciences, EarlyView.
We develop a full randomization of the classical hyper‐logistic growth model by obtaining closed‐form expressions for relevant quantities of interest, such as the first probability density function of its solution, the time until a given fixed population is reached, and the population at the inflection point.

Proposal of a non-linear model to adjust in vitro gas production at different incubation times

Bioscience Journal, 2023
This work aims to propose a new model named Gompertz-Von Bertalanffy bicompartmental (GVB), a combination of the models Gompertz and Von Bertalanffy. The GVB models is applied to fit the kinetic curve of cumulative gas production (CGP) of four foods (SS –

Bayesian approach for evaluating ammonia volatilization nitrogen losses in fertilizers applied to coffee plants [PDF]

Ciência e Agrotecnologia
Ammonia loss through volatilization is an important reason for the lower effectiveness of nitrogen fertilizers in coffee plants. The Bayesian approach uses informative prior distributions, which help improve the precision and accuracy of inferences ...
