Regional cosmic ray induced ionization and geomagnetic field changes
Cosmic ray induced ionization (CRII) is an important factor of outer space influences on atmospheric properties. Variations of CRII are caused by two different processes – solar activity variations, which modulate the cosmic ray flux in interplanetary space, and changes of the geomagnetic field, which affects the cosmic ray access to Earth. Migration of the geomagnetic dipole axis may greatly a...
متن کاملArcheomagnetic Intensity Spikes: Global or Regional Geomagnetic Field Features?
Variations of the geomagnetic field prior to direct observations are inferred from archeoand paleomagnetic experiments. Seemingly unusual variations not seen in the present-day and historical field are of particular interest to constrain the full range of core dynamics. Recently, archeomagnetic intensity spikes, characterized by very high field values that appear to be associated with rapid sec...
متن کاملLimitations in correlation of regional relative geomagnetic paleointensity
Time domain correlations of common features among relative paleointensity records from sedimentary cores are invaluable to paleomagnetism and paleoclimatology. Sediments with high accumulation rates might now provide millennial scale correlations of temporal variations in the geomagnetic dipole moment. Errors in the ages of paleomagnetic data samples however can make such correlations difficult...
متن کاملThe growing controversy about growth charts: WHO or regional?
Introduction Since production of WHO Multicenter Growth Reference Study (MGRS) growth standards in 2006, many countries have adopted the WHO charts for under five children [1]. In UK, WHO growth charts are used until 4 years [2] and in US only up to 2 years of age. Over-diagnosis of stunting and underweight in Asian children is likely with the use of these standards as Asian children are still ...
متن کاملOn multivariate control charts
Industrial production requires multivariate control charts to enable monitoring of several components. Recently there has been an increased interest also in other areas such as detection of bioterrorism, spatial surveillance and transaction strategies in finance. In the literature, several types of multivariate counterparts to the univariate Shewhart, EWMA and CUSUM methods have been proposed. ...
