Appropriate basis selection based on Bayesian inference for analyzing measured data reflecting photoelectron wave interference
Yasuhiko Igarashi, Fabio Iesari, Hiroyuki Setoyama +4
In this study, we applied Bayesian inference for extended X-ray absorption fine structure (EXAFS) to select an appropriate basis from among Fourier, wavelet and advanced Fourier ba…

Sparse Modeling analysis of Extended X-ray Absorption Fine Structure data using two-body expansion
Fabio Iesari, Hiroyuki Setoyama, Yasuhiko Igarashi +6
Analysis of extended X-ray absorption fine structure (EXAFS) data by the use of sparse modeling is presented. We consider the two-body term in the n-body expansion of the EXAFS sig…

Anisotropic structural dynamics of monolayer crystals revealed by femtosecond surface x-ray scattering
I-Cheng Tung, Aravind Krishnamoorthy, Sridhar Sadasivam +22
X-ray scattering is one of the primary tools to determine crystallographic configuration with atomic accuracy. However, the measurement of ultrafast structural dynamics in monolaye…
