A correlation between some characteristics of the visual evoked potentials and individual personality traits (by the Kettell scale) was revealed in 40 healthy subjects when they recognized facial expressions of anger and fear. As compared to emotionally stable subjects, emotionally unstable subjects had shorter latencies of evoked potentials and suppressed(More)
A reaction time and accuracy of visual recognition of emotions of joy, anger and fear in their relation to personality traits was studied in 68 healthy subjects. According to scores of Kettell Questionnaire all the participants were divided into two groups: emotionally unstable and emotionally stable, which differed in their emotional and communication(More)
Referring to the query complexity of property testing, we prove the existence of a rich hierarchy of corresponding complexity classes. That is, for any relevant function q, we prove the existence of properties that have testing complexity Θ(q). Such results are proven in three standard domains often considered in property testing: generic functions,(More)
others, for interesting and fruitful discussions. Thanks to Prof. Bruno Cour-celle, who first drew our attention to the most general matching polynomial. Thanks to Christian Hoffmann who found a gap in our proof of Difficult Point Property of the matching polynomial. Thanks to the members of my examiners committee, Prof. for their numerous valuable comments(More)
Acknowledgements I would like to thank my advisor, Prof. Hadas Shachnai, for her help and guidance throughout this research, and for pointing out many interesting new research directions. Hadas has patiently helped me make my first steps as a researcher, providing me with inspiration, freedom and encouragement. I would like to thank my co-author Prof. Tami(More)
Chorea is an abnormal hyperkinetic movement disorder. The reasons for chorea are diverse and include hereditary, endocrine, toxic, vascular, infectious, autoimmune, and metabolic etiologies. We present a 64-year-old woman with acute chorea who suffered from diabetes with recurrent hypoglycemia, and chronic renal failure treated by hemodialysis. The full(More)
We consider natural graph property tests, which act entirely independently of the size of the graph being tested (not just having a number of queries independent of the size). We introduce the notion of graph properties being inflatable — closed under taking (balanced) blowups — and show that the query complexity of natural tests for a property are related(More)
