ACE is calculated by summing the squares of a cyclones sustained wind speed, every six hours as long as the system is at or above tropical storm intensity and either tropical or subtropical. The calculation of the PDI is similar in nature to ACE, with the major difference being that wind speeds are cubed rather than squared. The Hurricane Surge Index is a metric of the potential damage a storm may inflict via storm surge. It is calculated by squaring the dividend of the storms wind speed and a climatological value (33 metres per second (74 mph)), and then multiplying that quantity by the dividend of the radius of hurricane-force winds and its climatological value (96.6 kilometres (60.0 mi)).
It has also been studied as an adjuvant in two other trials in people with schizophrenia, around fifty people overall, and did not appear to have an effect.There have been some trials to see if cyproheptadine could reduce sexual dysfunction caused by SSRI  and antipsychotic medications.Cyproheptadine has been studied for the treatment of posttraumatic stress disorder. Veterinary use
Cyproheptadine is used in cats as an appetite stimulant: 1371  and as an adjunct in the treatment of asthma. Possible adverse effects include excitement and aggressive behavior. The elimination half-life of cyproheptadine in cats is 12 hours.Cyproheptadine is a second line treatment for pituitary pars intermedia dysfunction in horses. == References ==
