Judo in Canada Canada there are six "kyū" grades for seniors (people 16 years of age or older), eleven "kyū" grades for juniors (people under the age of 16), and ten "dan" grades that are restricted to seniors. Both senior and junior students begin as white belts ("rokkyū") and progress with promotion through yellow, orange, green, and blue, to brown belt ("ikkyū"). Half-grades for juniors were introduced in 2010 and are represented by belts that combine the colours of the previous grade and the next grade (a white and yellow belt, for example, represents a half-grade between "rokkyū" and "gokyū", which the grading
Low-degree saturation Low-degree saturation In a scale-free network the degree distribution follows a power law function. In some empirical examples this power-law fits the degree distribution well only in the high degree region, however for small degree nodes the empirical degree-distribution deviates from it. See for example the network of scientific citations. This deviation of the observed degree-distribution from the theoretical prediction at the low-degree region is often referred as low-degree saturation. Typically the empirical degree-distribution deviates downwards from the power-law function fitted on higher order nodes, which means low-degree nodes are less frequent in real data than what is predicted by
