The classical example of thermionic emission is the emission of electrons from a hot cathode into a vacuum (also known as thermal electron emission or the Edison effect) in a vacuum tube. The hot cathode can be a metal filament, a coated metal filament, or a separate structure of metal or carbides or borides of transition metals.
Low confidence regions are areas for which there s a small amount of DNA evidence found in your sample. All ethnicities with predicted percentages of less than 4.5% appear as low confidence regions. Inferior complex is low complex .
The statement ends with a series of recommendations, the first of which is that the scientific community do its best to make these issues clear to the public. The public, in turn, has a duty to pay attention to scientists if they're going to take ancestry testing seriously.But scientists can do a lot more.ut note the term prevalent.. As the ASHG statement points out, most of the frequencies of DNA markers have known error rates. Something that's prevalent in say, Pacific Islanders, will often show up in an unrelated population, like Scandinavians, at a measurable rate.
