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 results typically give you a 95% confidence interval, which is a measure of the statistical strength of the test. The only way to achieve 100% accuracy in an ancestry test would be to go back in time and test each and every one of your ancestors.Since this is impossible, we rely on statistics to make a prediction of your most likely ancestry mix.he only way to achieve 100% accuracy in an ancestry test would be to go back in time and test each and every one of your ancestors.
