Sleep data were obtained on 11 patients who had survived traumatic events and who complained of sleep disturbances. Each was awakened from REM and non-REM sleep for dream recall. The patients had lower sleep efficiency indices (because of prolonged sleep latency and larger amounts of "awake" plus "movement" time within sleep periods), shorter REM time, and… (More)
Eleven patients who had combat neuroses resulting from the 1973 Yom Kippur War and complained of sleep disturbances were studied in a sleep laboratory. Sleep-onset insomniacs, dream-interruption insomniacs, and pseudoinsomniacs were differentiated on the basis of electrophysiologic recordings. Compared with normal controls who actively participated in the… (More)
This paper presents an effective method for computing Standard bases for the local ring of an algebroid branch and for its module of Kähler differentials. This allows us to determine the semigroup of values of the ring and the values of its Kähler differentials, which in the case of complex analytic branches are, respectively, important topological and… (More)
In March and April 1983, an epidemic of "mysterious gas poisoning" occurred in the Jordan West Bank region, affecting more than 900 persons, predominantly schoolgirls. That both Arabs and Israelis believed there was an etiologic poisonous substance reflected their longstanding conflict. Israeli newspaper reports, opinions by Arab and Israeli physicians, and… (More)
We perform the analytic classification of plane branches of multiplicity less or equal than four. This is achieved by computing a Standard basis for the modules of Kähler differentials of such branches by means of the algorithm we developed in  and then applying the classification method for plane branches presented in .
1. Introduction. In this paper we study some properties of the special family of Artin–Schreier curves related to the theory of polar curves we developed in . Our goal is to show how this theory can be carried out in concrete situations and also show how it can be used to determine new upper bounds for the number of rational points of projective plane… (More)
Two depressed patients with long QT syndrome who experienced torsade de pointes ventricular tachycardia when treated with psychotropic drugs are discussed. These cases emphasize the significance of electrocardiographic evaluation of depressed patients, particularly in patients who show evidence of a long QT interval.
