a training set is drawn using bootstrap aggregating (bagging). The decision tree is built by rule-based splitting of the bagging sample into subsets, maximizing the variance between the subsets (Venables and Ripley2002). At each split in the learning process, a random subset of explanatory vari...
In the ocean, just as on land, dispersal regulates population connectivity and is therefore a fundamental driver of biogeographic and genetic patterns in oceanic islands (Cowie and Holland2006). But what constitutes a physical barrier to dispersal in the ocean is largely dependent on the mode of ...
where N is the total number of individuals in the population, B is the number of births, D is the number of deaths, b and d are the per capita rates of birth and death respectively, and r is the per capita rate of population change. This formula can be read out as the rate of ...
Finally, we present the promises and challenges that arise when seeking to incorporate microbiome data in dietary planning and portray the anticipated revolution that the field of nutrition is facing upon adopting these novel concepts. Key points Common multifactorial diseases in both industrialized and ...
Its respect for the syntax of a physical law is not the issue we’re addressing. We want to know something much more plastic — more plastic in the way that meaning is more plastic than a rigid grammar or mathematical formula. That is, we want to know whether the folding is consistent ...
In adults, the microbiome is fully established and is characterized by a great richness and diversity of the bacteria present.29Each individual has their own microbiota profile.4The adult microbiome is important for maintaining health, by supporting immune system2, 16and helping to maintain a ...
And if by "culture" one means not just local ethnic cultures but the aggregate cul- ture of the human species, then this term very nearly represents this vast sphere of technology that I have been talking about. But the term culture falls short in one critical way. It is too small. ...
The state (and diversity) of your gut microbiota is fairly stable in adulthood, but that’s not the case when you take antibiotics. They can wipe out badandgood bacteria. That’s like depleting a garden of all its organic material, richness, and nutrients at once. And that wonderful, fer...
Regardless of where you’re starting — never eaten a green thing ever, or just want some new ways to eat plants — there is a simple formula you can use to make bitterness less intense, more palatable, and much more enjoyable: Challenge. Complement. Cushion. 1. Challenge. Find a bitter...
