Testing and selection cosmological models with dark energy

, 2006
It is described dynamics of a large class of accelerating cosmological models in terms of dynamical systems of the Newtonian type. The evolution of the models is reduced to the motion of a particle in a potential well parameterized by the scale factor ...

Comparison of non-linear models to describe the growth in the Andalusian turkey breed

Italian Journal of Animal Science, 2021
Seven non-linear growth models were compared in the Andalusian turkey, an endangered native breed. To this aim, turkeys were weekly weighted until they reached 35 weeks.

Scaling cosmology with variable dark-energy equation of state

, 2012
Interactions between dark matter and dark energy which result in a power-law behavior (with respect to the cosmic scale factor) of the ratio between the energy densities of the dark components (thus generalizing the LCDM model) have been considered as an

The topology of large Open Connectome networks for the human brain [PDF]

, 2016
The structural human connectome (i.e.\ the network of fiber connections in the brain) can be analyzed at ever finer spatial resolution thanks to advances in neuroimaging.

On the Flexibility of the Transmuted Inverse Exponential Distribution [PDF]

, 2017
This research demonstrates that the Transmuted Inverse Exponential distribution is more robust than the Inverse Exponential distribution. The comparison was made using two real life data sets and the performance of the competing models were rated ...

Inferential Statistics from Black Hispanic Breast Cancer Survival Data

The Scientific World Journal, 2014
In this paper we test the statistical probability models for breast cancer survival data for race and ethnicity. Data was collected from breast cancer patients diagnosed in United States during the years 1973–2009.

Model selection criteria and quadratic discrimination in ARMA and SETAR time series models [PDF]

, 2004
We show that analyzing model selection in ARMA time series models as a quadratic discrimination problem provides a unifying approach for deriving model selection criteria.
