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 .
Another really cool â and free! â way to get a âsecond opinionâ about your ethnicity estimates, and especially your low confidence regions is to download your DNA from Ancestry (or whichever company you used to test) and upload it to Gedmatch.
