Emetophobia Frank M. Datillio's clinical case study, a situation where anorexia results from emetophobia is mentioned. Datillio says, "...in one particular case report, atypical anorexia in several adolescent females occurred as a result of a fear of vomiting that followed a viral illness as opposed to the specific desire to lose weight or because of an anxiety reaction." In cases such as this, many emetophobes may also have avoidant/restrictive food intake disorder (ARFID), which is characterized by a general disinterest in food, sensory issues with food (taste, texture, look, smell) or a fear of adverse consequences from eating (vomiting or choking).
Particular values of the Riemann zeta function for formula_24, For the first few odd natural numbers one has It is known that "ζ"(3) is irrational (Apéry's theorem) and that infinitely many of the numbers "ζ"(2"n" + 1) ("n" ∈ N) are irrational. There are also results on the irrationality of values of the Riemann zeta function at the elements of certain subsets of the positive odd integers; for example, at least one of "ζ"(5), "ζ"(7), "ζ"(9), or "ζ"(11) is irrational. The positive odd integers of the zeta function appear in physics, specifically correlation functions of antiferromagnetic XXX spin chain. Most of the identities following below are provided
