Excitation of nightside magnetosonic waves observedby Van Allen Probes [PDF]
, 2014 During the recovery phase of the geomagnetic storm on 30-31 March 2013, Van Allen Probe A detected enhanced magnetosonic (MS) waves in a broad range of L = 1.8-4.7 and magnetic local time (MLT) = 17-22 h, with a frequency range ∼10-100 Hz.

BACE1 Inhibitor, Neuroprotective, and Neuritogenic Activities of Melatonin Derivatives
Scientia Pharmaceutica, 2020 Alzheimer’s disease (AD) is a common chronic neurodegenerative disorders. Melatonin (MLT) has been reported to be neuroprotective agent, and its modified structures exhibit potent antioxidant and anti-inflammation activities.

Revised time-of-flight calculations for high-latitude geomagnetic pulsations using a realistic magnetospheric magnetic field model [PDF]
, 2005 We present a simple time-of-flight analysis of Alfvén pulsations standing on closed terrestrial magnetic field lines. The technique employed in this study in order to calculate the characteristic period of such oscillations builds upon earlier time-of ...

The spatial distribution of region 2 field-aligned currents relative to subauroral polarization stream [PDF]
Annales Geophysicae, 2014 To test the current-generation model of subauroral polarization stream (SAPS), we have investigated the relative positions of field-aligned currents (FACs) with respect to SAPS in a statistical way by using CHAMP (CHAllenging Minisatellite Payload ...

Observations of convection in A-type stars [PDF]
, 2004 Convection and turbulence in stellar atmospheres have a significant effect on the emergent flux from A-type stars. The recent theoretical advancements in convection modelling have proved a challenge to the observers to obtain measurements with sufficient

A study of omega bands and Ps6 pulsations on the ground, at low altitude and at geostationary orbit [PDF]
, 1999 We investigate the electrodynamic coupling between auroral omega bands and the inner magnetosphere. The goal of this study is to determine the features to which omega bands map in the magnetosphere.

Multiple, discrete arcs on sunward convecting field lines in the 14‐15 MLT region [PDF]
Journal of Geophysical Research: Space Physics, 1994 Ionospheric plasma flow measurements and simultaneous observations of thin (∼0.2° invariant latitude (ILAT)), multiple, longitudinally extended auroral arcs of transient nature within 74°‐76° ILAT and 1030‐1130 UT (∼14‐15 MLT) on January 12, 1989, are reported.
