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 larger the amount of an ethnicity that appears in a test, the more confidence weâre able to attribute to our estimate of that ethnicity. Because low confidence regions are regions for which smaller amounts of evidence appears, our confidence in the percentage of DNA that comes from a low confidence region is necessarily low.
