    Effects of Geometries and Substructures of ICMEs on Geomagnetic Storms

    To better understand geomagnetic storm generations by ICMEs, we consider the effect of substructures (magnetic cloud, MC, and sheath) and geometries (impact location of flux-rope at the Earth) of the ICMEs. We...

    Heights of Coronal Mass Ejections and Shocks Inferred from Metric and DH Type II Radio Bursts

    A set of 27 continuous events that showed extension of metric Type-II radio bursts (m-Type IIs) into the deca–hectometric (DH) domain is considered. The coronal mass ejections (CMEs) associated with this type ...

    Overproduction of AcrR increases organic solvent tolerance mediated by modulation of SoxS regulon in Escherichia coli

    Acriflavine resistance regulator (AcrR), a local transcription factor, regulates the expression of the acrRAB genes associated with the AcrAB-TolC multidrug efflux pump. Screening of organic solvent tolerance (OS...

    Dependence of Geomagnetic Storms on Their Associated Halo CME Parameters

    We compare the geoeffective parameters of halo coronal mass ejections (CMEs). We consider 50 front-side full-halo CMEs (FFH CMEs), which are from the list of Michalek, Gopalswamy, and Yashiro (Solar Phys. ...
