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 .
Higher Beta hCG Levels are Correlated with Higher Occurrence of Twins and High-Order Multiples. I looked at the data two ways. First, I analyzed the median beta hCG score for each type of pregnancy (singleton, twins, high-order multiple), day by day. This means that half the pregnancies in the category had higher beta hCG levels and half had lower beta hCG levels. Median hCG Levels for Singleton, Twin and High-Order Multiples Pregnancy As you can see in the graph, the median beta level was always higher the more babies a woman carried.
