Query: Excitation of low-n TAE instabilities by energetic particles in global
  gyrokinetic tokamak plasmas   The first linear global electromagnetic gyrokinetic particle simulation on
the excitation of toroidicity induced Alfven eigenmode (TAE) by energetic
particles is reported. With an increase in the energetic particle pressure, the
TAE frequency moves down into the lower continuum.
