QUICKSELECT Revisited
We give an overview of the running time analysis of the random divide-and-conquer algorithm FIND or QUICKSELECT. The results concern moments, distribution of FIND’s running time, the limiting distribution, a stochastic bound and the key: a stochastic fixed point equation.
متن کاملThe iodine-plutonium-xenon age of the Moon-Earth system revisited.
Iodine-plutonium-xenon isotope systematics have been used to re-evaluate time constraints on the early evolution of the Earth-atmosphere system and, by inference, on the Moon-forming event. Two extinct radionuclides ((129)I, T1/2=15.6 Ma and (244)Pu, T1/2=80 Ma) have produced radiogenic (129)Xe and fissiogenic (131-136)Xe, respectively, within the Earth, the related isotope fingerprints of whic...
متن کاملPENDRED\'S SYNDROME REVISITED
Pendred's syndrome is defined as a triad of congenital perceptive hearing loss, goiter, and abnormal perchlorate test. Three brothers with Pendred's syndrome [P.S.] are reported. The oldest brother has hearing loss (he has been deaf and mute since childhood) and has a large goiter. A thyroid scan revealed euthyroid multinodular goiter and a perchlorate test was performed, and reported abno...
متن کاملUSHER\'S SYNDROME REVISITED
Usher's syndrome is a genetically inherited autosomal recessive disorder resulting in the double handicap of deafness and progressive blindness, known as retinitis pigmentosa. The disease is also associated with psychoses, mental retardation, and other major neurophysiological changes. It appears to be more common among Jewish individuals and consanguinous marriages. While it is rare in th...
متن کاملPreparation of Neutron-activated Xenon for Liquid Xenon Detector Calibration
We report the preparation of neutron-activated xenon for the calibration of liquid xenon (LXe) detectors. Gamma rays from the decay of xenon metastable states, produced by fast neutron activation, were detected and their activities measured in a LXe scintillation detector. Following a five-day activation of natural xenon gas with a Cf (4× 10 n/s) source, the activities of two gamma ray lines at...
