Given a target concept with an arbitrary number of classes together with a sample of unlabeled examples from the target space (the working set), our purpose is to identify representative instances covering all classes while posing as few queries as possible, where a query consists of requesting a label to a specific instance.
Analysis under anoxic conditions must be carefully planned as well, since even a few minutes of exposure to the atmosphere on the way to an instrument can significantly oxidize a sample (of, for example, reduced iron minerals), including oxygen diffusion into supposedly sealed sample containers when shipping, or even oxidation that occurs during analysis.
Users can break off a sample of, for example, ecstasy and the lab can detect if they've bought a fake pill or not.
For example, a sampling of the research topics that are appropriate includes: Bioenergetics.
Besides providing information on the disease regulation networks in rice, they also represent a solid sample of examples for the evaluation of transgenic strategies.
But once one examines a broader sample of examples, and reviews situations in which the rival and narrow egalitarianism yield opposed recommendations as to what should be done, one should conclude that the rival, and not any version of narrow egalitarianism, should be affirmed as non-instrumentally valuable and incorporated into the set of fundamental moral principles.
For example, within a sampling of the largest sentence classification category, 'Experiment was Performed', curators marked nearly half of the sentences as containing no GO term.
For example, among a sampling of 11 patients with the disease, six patients showed tissue-specific silencing of the maternally inherited functional RYR1 allele, which apparently resulted from cytosine hypermethylation of that allele [ 56].
If a sample of a tree (for example) contains 64 grams (g) of radioactive carbon after 5,730 years it will contain 32 g, after another 5,730 years that will have halved again to 16 g.
A subset of these studies find evidence of provider responses to a reduction in liability within samples of patients with certain diagnoses, or among a sample of the population (for example, Medicare patients).
This degree of accuracy is enough to distinguish, for example, a sample of water from a sample of pure hydrogen peroxide: the ratio of oxygen to hydrogen is reconstructed to within 8±0.5% of the true value.
