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).
Quasiperiodic function periodic functions and that article should be consulted. The more vague and general notion of quasiperiodicity has even less to do with quasiperiodic functions in the mathematical sense. A useful example is the function: If the ratio "A"/"B" is rational, this will have a true period, but if "A"/"B" is irrational there is no true period, but a succession of increasingly accurate "almost" periods. Quasiperiodic function In mathematics, a quasiperiodic function is a function that has a certain similarity to a periodic function. A function formula_1 is quasiperiodic with quasiperiod formula_2 if formula_3, where formula_4 is a ""simpler"" function than
