Studies on modified limited-memory BFGS method in full waveform inversion
Frontiers in Earth Science, 2023 Full waveform inversion (FWI) is a non-linear optimization problem based on full-wavefield modeling to obtain quantitative information of subsurface structure by minimizing the difference between the observed seismic data and the predicted wavefield. The

A Combined Conjugate Gradient Quasi-Newton Method with Modification BFGS Formula
International Journal of Analysis and Applications, 2023 The conjugate gradient and Quasi-Newton methods have advantages and drawbacks, as although quasi-Newton algorithm has more rapid convergence than conjugate gradient, they require more storage compared to conjugate gradient algorithms.

Chaplygin's method is Newton's method
Journal of Mathematical Analysis and Applications, 1978 This method has been extended to ordinary differential equations in [w” by Lusin [6], to ordinary differential equations in Banach spaces by Mlak [8] and to parabolic equations by Mlak [7] and Szarki [15, Sect. 661. In each case a different type of hypotheses is assumed. A formal generalization considered by Wazewski [18] has been found by Schelkunoff [

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
