Allometric Exponent and Randomness
An allometric height-mass exponent γ gives an approximative power-law relation 〈M〉 ∝ H between the average mass 〈M〉 and the height H , for a sample of individuals. The individuals in the present study are humans but could be any biological organism. The sampling can be for a specific age of the individuals or for an age-interval. The body-mass index (BMI) is often used for practical purposes wh...
متن کاملUncertainty in allometric exponent estimation: a case study in scaling metabolic rate with body mass.
Many factors could influence the allometric scaling exponent beta estimation, but have not been explored systematically. We investigated the influences of three factors on the estimate of beta based on a data set of 626 species of basal metabolic rate and mass in mammals. The influence of sampling error was tested by re-sampling with different sample sizes using a Monte Carlo method. Small rand...
متن کاملω-Change Randomness and Weak Demuth Randomness
We extend our work on difference randomness. Each component of a difference test is a Boolean combination of two r.e. open sets; here we consider tests in which the k component is a Boolean combination of g(k) r.e. open sets for a given recursive function g. We use this method to produce an alternate characterization of weak Demuth randomness in terms of these tests and further show that a real...
متن کاملRandomness and Pseudo-Randomness in Discrete Mathematics
The discovery, demonstrated in the early work of Paley, Zygmund, Erdős, Kac, Turán, Shannon, Szele and others, that deterministic statements can be proved by probabilistic reasoning, led already in the first half of the century to several striking results in Analysis, Number Theory, Combinatorics and Information Theory. It soon became clear that the method, which is now called the probabilistic...
متن کاملAllometric Scaling in Biology
The design of living beings is not only a matter of molecular biology but also of geometry and physics. This was once more demonstrated with a biophysical model by G. B. West et al. (1) that had been fine-tuned to predict the famous scaling law of metabolism (2), namely a 3/4 power relation between body mass and energy consumption. While properties and predictions of the model are remarkable, a...
