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).
Hurwitz zeta function function of the complex argument "s" ("vide supra"), leading in each case to the difficult study of the zeros of Riemann's zeta function. In particular, there will be no zeros with real part greater than or equal to 1. However, if 0<"q"<1 and "q"≠1/2, then there are zeros of Hurwitz's zeta function in the strip 1<Re("s")<1+ε for any positive real number ε. This was proved by Davenport and Heilbronn for rational or transcendental irrational "q", and by Cassels for algebraic irrational "q". The Hurwitz zeta function occurs in a number of striking identities at rational values. In particular, values in
