This could reflect some biological instances, or alternatively could be related to noise deriving from technological issues, as the yeast dataset is a none year old two color array.
Thus, the expected search space of possibilities following the constraint on connectivity and knowledge of L distinct transitions is ((n k ) ) n 2 n 2 k (1 − 2 − k ) L. The number is still huge, for instance for our biological example presented later n = 6, k = 3 and L = 5, ((n k ) ) n 2 n 2 k (1 − 2 − k ) L ≈ 1.65 × 10 10.
Conversely, 'transport' is in the dictionary, and while it was present in over 140 of the labeled biological process instances, it also appeared over 71 times unlabeled, where non-T4SS transport was described or where it specified a cellular component instead.
The small number of instances constituting each biological dataset (three instances per dataset) prevents a clear statistical characterization of the performances of CRM2 in terms of accuracy.
But while some of his positions are unfashionable that language is a purely cultural acquisition and not a biological system, for instance—others are quite mainstream.
And yet it is not hard to imagine less heartwarming consequences of this new revolution — biological weapons, for instance, or deadly viruses or mutant strains of common chemicals, not to mention the possibility of deadly errors.
Outside backers tend to direct their support toward disciplines that offer practical, salable results — the biological sciences, for instance, and the quantitative social sciences — and universities themselves have an incentive to channel money into work that will generate patents for them.
One opens the book with hopes for insight into the historical roots of today's controversies about classifying human beings — whether IQ tests really measure a biological trait, for instance, or whether it makes sense to use race or ethnicity in medicine.
What's changed in recent years is that the idea of innate biological differences – for instance in cognitive abilities or communication skills – has gained academic credibility and powerful champions in widely admired researchers such as Simon Baron Cohen (author of The Essential Difference) and Steven Pinker.
