Query: ConceFT: Concentration of Frequency and Time via a multitapered
  synchrosqueezed transform   A new method is proposed to determine the time-frequency content of
time-dependent signals consisting of multiple oscillatory components, with
time-varying amplitudes and instantaneous frequencies. Numerical experiments as
well as a theoretical analysis are presented to assess its effectiveness.
