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 .
About low confidence regions To calculate your ethnicity, we run 40 separate tests on randomly selected portions of your DNA. The bottom number in a range is the smallest amount of an ethnicity that appeared during the 40 analyses, and the top number in a range is the largest amount of an ethnicity that appeared.
