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).
Dirichlet eta function the formula_19 function is then analytic for formula_15, a region which includes the line formula_8. Now we can define correctly, where the denominators are not zero, or Since formula_24 is irrational, the denominators in the two definitions are not zero at the same time except for formula_25, and the formula_26 function is thus well defined and analytic for formula_15 except at formula_25. We finally get indirectly that formula_29 when formula_13: An elementary direct and formula_32-independent proof of the vanishing of the eta function at formula_13 was published by J. Sondow in 2003. It expresses the value of the eta function
