Spatial-Dependent Hamiltonian Formulation of Cross-Mode Modulation
IEEE Photonics Journal, 2020 In the absence of random mode mixing (RMM), linearization of the cross-mode modulation (XMM) under pump-probe configuration is in general complicated because the evolution of the pump light depends on the local mode decomposition of itself. In this work,

Effect of Linearization in a WNT Signaling Model [PDF]
Computational and Mathematical Methods in Medicine, 2019 A nonlinear model consisting of a system of coupled ordinary differential equations (ODE), describing a biological process linked with cancer development, is linearized using Taylor series and tested against different magnitudes of input perturbations, in order to investigate the extent to which the linearization is accurate.
