Unveiling urban area growth dynamics: insights from a comprehensive study of urban area growth curves

open access: yesInternational Journal of Digital Earth
Amidst rapid global urbanization, comprehending urban area growth (UAG) dynamics is vital for urban planning and sustainability. Despite ample urban development research, the historical developmental patterns of UAG remain underexplored.

Study on the cohesive shear characteristics and intrinsic modelling of the root–tailing soil interface of Amorpha fruticosa

open access: yesScientific Reports, 2022
To study the soil consolidation effect of shrub plant roots on tailings soil and to explore the frictional characteristics of plant roots on tailings soil, three experimental conditions of the root–soil interface were established by using a modified ...

Assessing the Diversity of the Form of Age-Specific Changes in Adult Mortality from Captive Mammalian Populations

open access: yesDiversity, 2020
Actuarial senescence (i.e., the age-specific increase in mortality rate) is pervasive across mammalian species, but our current understanding of the diversity of forms that actuarial senescence displays across species remains limited.

On Hyperbolic Gompertz Growth Model

open access: yes, 2015
We proposed a Hyperbolic Gompertz Growth Model (HGGM), which was developed by introducing a shape parameter (allometric). This was achieved by convoluting hyperbolic sine function on the intrinsic rate of growth in the classical gompertz growth equation.

Precision livestock farming: real-time estimation of daily protein deposition in growing–finishing pigs

open access: yesAnimal, 2020
Precision feeding using real-time models to estimate daily tailored diets can potentially increase nutrient utilization efficiency. However, to improve the estimation of amino acid requirements for growing–finishing pigs, it is necessary to accurately ...

Scaling Function, Universality and Analytical Solutions of Generalized One-Species Population Dynamics Models

open access: yes, 2010
We consider several one-species population dynamics model with finite and infinite carrying capacity, time dependent growth and effort rates and solve them analytically.

New Modified Gompertz Probability Distribution With Flexible Hazard Functions

open access: yesJournal of Probability and Statistics
This paper introduces a new probability model called the modified Gompertz distribution from the base Gompertz distribution by combining its hazard function with first and second degree polynomial (linear and quadratic) functions.

An explanation for negligible senescence in animals

open access: yesEcology and Evolution, 2022
Negligible or negative senescence occurs when mortality risk is stable or decreases with age, and has been observed in some wild animals. Age‐independent mortality in animals may lead to an abnormally long maximum individual lifespans and be incompatible
