Transpolar arcs observed simultaneously in both hemispheres
Two coexisting transpolar arcs are observed on 31 August 2005. We track the formation and motion of the arcs in both the Northern and Southern Hemispheres, using data from two independent satellites (Imager for Magnetopause to Aurora Global Exploration and a Defence Meteorological Satellite Program satellite). The observations are supported by supplementary ground-based ionospheric convection d...
متن کاملPhonological and Orthographic Processing : One or Both Hemispheres ?
Laterality refers to the contention that the left and right hemisphere of the brain process information differently. Currently under debate is whether there is laterality of phonological and orthographic processing. Two experiments used a lexical decision task and a priming procedure along with a distractor to the left or right visual field to test laterality. Experiment I manipulated sound sim...
متن کاملt-Pancyclic Arcs in Tournaments
Let $T$ be a non-trivial tournament. An arc is emph{$t$-pancyclic} in $T$, if it is contained in a cycle of length $ell$ for every $tleq ell leq |V(T)|$. Let $p^t(T)$ denote the number of $t$-pancyclic arcs in $T$ and $h^t(T)$ the maximum number of $t$-pancyclic arcs contained in the same Hamiltonian cycle of $T$. Moon ({em J. Combin. Inform. System Sci.}, {bf 19} (1994), 207-214) showed that $...
متن کاملMulti-instrument observation of simultaneous polar cap auroras on open and closed magnetic field lines
This paper presents observations of polar cap auroral features on 19 January 2008, evaluated using multiple instruments with near-simultaneous observations in both hemispheres. Analysis of the features indicates that there are at least two formation mechanisms/types of polar cap aurora occurring simultaneously on different magnetic field topologies (one on open and the other on closed magnetosp...
متن کاملSeasonal variation in hemoglobin A1c: is it the same in both hemispheres?
INTRODUCTION There are several reports from locations in the northern hemisphere of seasonal variation in hemoglobin A1c (HbA1c) levels with higher values noted in the cooler months. The variation has been attributed to holiday seasons, temperature differences, and changes in diet. This article describes the seasonal variation in both hemispheres and in a country on the equator with minimal tem...
