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 .
Although I am not privy to the âbehind-the-scenesâ at Ancestry.com, I donât believe that there are serious issues with AncestryDNAâs Genetic Ethnicity Prediction. Ancestry.comâs DNA arm has a solid scientific team and a large and valuable reference database. Indeed, Ancestry.com is well aware of the limitations and challenges that their Genetic Ethnicity Prediction brings: We use cutting-edge science as a base for our predictions, but that comes with its own inherent challenges.
