Wave Equation‐Based Local Traveltime Inversion
Earth and Space Science, 2020 Full waveform inversion (FWI) is a strongly nonlinear optimization problem, which suffers from cycle skipping when the initial velocity model is not good enough or the seismic data lack low frequencies.

Finite-Frequency SKS Splitting: Measurement and Sensitivity Kernels [PDF]
, 2008 Splitting of SKS waves caused by anisotropy may be analyzed by measuring the splitting intensity, i.e., the amplitude of the transverse signal relative to the radial signal in the SKS time window. This quantity is simply related to structural parameters.

Indonesian inquiry: A narrative of biocultural teaching on Sulawesi Utara
British Educational Research Journal, EarlyView.Abstract Using phenomenology, narrative inquiry and autoethnographic approaches, this study analyses a program of faculty development conducted alongside the delivery of an international field school. Through this study, we explore the value and benefits of inter‐cultural field programming and how these might serve to complement or to redress ...
