— We study the role of pricing policies in multiple service class networks. We first argue that some form of service-class sensitive pricing is required for any multiclass service discipline' to attain the desired level of performance. Borrowing heavily from the Nash implementation paradigm in economics, we then present an abstract formulation of service… (More)

We argue that some form of graduated prices are required in order for a ng multiclass service discipline to have the desired effect. Moreover, we demonstrate through simulation that it is possible to set the prices so that every user is more satisfied with the combined cost and… (More)

Five observations in adult subjects (4 female, 1 male) in which the administration of chlordesmethyldiazepam (2-4 mg/day) alone, or in association with other psychodrugs has demonstrated a specific anti-erotic action, with a short therapeutic latency period, reversible, and not found in other benzodiazepines (chlordiazepoxide, diazepam, lorazepam,… (More)
A detailed presentation of 15 case-histories of subjects of both sexes, drawn from all decennies of life from the first to the eight, suggesting a syndrome originated from a possible GABA deficiency, is carefully made. Such syndrome is believed to be characterized by basic depressive state, loss of the habit of stretching oneself, sleep disorders, mostly… (More)
The case is reported of a 23 year old patient, who at the age of nine underwent neurosurgery for an angiomatous meningioma of the right temporal lobe, and immediately afterwards realized he was able to speak backwards nearly as well as normally. Presently, the patient still retains this ability which is associated with analogous mirror reading and writing.… (More)
A case of eye-lid nystagmus, synchronous to a vertical nystagmus, in a 35 year old female patient is extensively presented. Vestibular examinations and BAEPs were suggestive of an impairment of pontomesencephalic structures. Following an aspecific drug therapy the s. had a noticeable improvement with reduction of the symptomatology.
