The correlation between mid-latitude trough and the plasmapause
[1] We use simultaneous global observations of the mid-latitude trough and the plasmapause to experimentally prove a long-standing conjecture of magnetosphereionosphere couplingnamely the mid-latitude trough and plasmapause are on the same field line. Global Ionospheric Maps (GIM), generated using ground based GPS receivers, are used to detect the globally extended mid-latitude trough; while gl...
متن کاملMonitoring the plasmapause using geomagnetic field line resonances
[1] This paper discusses the use of ground magnetometer data to derive plasma mass density profiles of the dayside plasmapause region with spatial and temporal resolution in the range 0.15–0.4 RE and 20–60 min. This is achieved using cross-phase techniques to identify field line resonance signatures that are not apparent in power spectra. Under quiet conditions, mass density profiles do not sho...
متن کاملQUICKSELECT 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 کاملPlasmapause Morphology Determined from an Empirical Ionospheric Convection Model
The steady state electric potentials derived from empirical ionospheric onvection models were mapped to the magnetospheric equatorial plane and added to the Earth's rotational field to examine the local time dependence of the plasmapause radius. The last closed equipotential line was assumed to be the plasmapause. The sensitivity of plasmapause shape and size derived in this way was studied by ...
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...
