Theoretical models such as those 5 Pc. Sectional of Gompertz and Weibull are commonly used to study senescence in survival for humans and laboratory or captive animals.For wild populations of vertebrates, senescence in survival has more commonly been assessed by fitting simple linear or quadratic relationships between survival and age.By using appr
At present, the path-planning algorithm based on the grid map is generally adopted in the field of Tail Lights quadruped robot and the obtained environmental information is represented by a standardized grid map.In this paper, the ADFA* algorithm introduces a dilation factor based on the DFA* to solve the path planning problem under the constraint
Migratory birds have evolved elaborate physiological adaptations to travelling, the implications for their susceptibility to avian influenza are however unknown.Three groups of stonechats (Saxicola torquata) Tail Lights from (I) strongly migrating, (II) weakly migrating and (III) non-migrating populations were experimentally infected with HPAIV H5N
OBJECTIVE: To demonstrate the analytical value of a cubic parameterization of the age curve of fertility and to explore its features, especially its usefulness in separating fertility level and fertility timing.METHODS: Using mathematical analysis, the cubic fertility curve is derived and examined in both continuous and discrete forms.RESULTS: The
