Emetophobia in public or having to witness someone else vomit, as the start of the emetophobia. They may also be afraid of hearing that someone is feeling like vomiting or that someone has vomited, usually in conjunction with the fears of seeing someone vomit or seeing vomit. There is a strong agreement in the scientific community that there is no specific cause of emetophobia. Some emetophobics report a traumatic experience with vomiting, always in childhood. Some suggest that sufferers are victims of childhood abuse – sexual or physical. While this is occasionally true, it seems to be no more prevalent than
Complexity function applicable, which may be taken to be uniformly recurrent or even uniquely ergodic. For "x" a real number and "b" an integer ≥ 2 then the complexity function of "x" in base "b" is the complexity function "p"("x","b","n") of the sequence of digits of "x" written in base "b". If "x" is an irrational number then "p"("x","b","n") ≥ "n"+1; if "x" is rational then "p"("x","b","n") ≤ "C" for some constant "C" depending on "x" and "b". It is conjectured that for algebraic irrational "x" the complexity is "b" (which would follow if all such numbers were normal) but all that
