A Novel Optimized Local Linearization Hybrid Block Method for Chaotic Systems: Applications to Stretch‐Twist‐Fold Flow and Bond Orbital Chaotic Attractors

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The numerical approximation of nonlinear chaotic differential systems, such as the modified stretch‐twist‐fold (STF) flow and multi‐bond chaotic attractors, presents a significant challenge due to their sensitive dependence on initial conditions and complex dynamics where analytical solutions are unattainable.

q-identities from Lagrange and Newton interpolation

open access: yesAdvances in Applied Mathematics, 2003
Combining Newton and Lagrange interpolation, we give $q$-identities which generalize results of Van Hamme, Uchimura, Dilcher and Prodinger.

Colonization and spatiotemporal distribution of bruchid pests in lentil and faba bean fields

open access: yesPest Management Science, EarlyView.
This study of 104 fields identifies Bruchus signaticornis in lentils and B. rufimanus in faba beans as the sole grain‐damaging species. Their uniform distribution within fields and the strong effect of regulatory factors on larvae and egg survival emphasize the need for species‐specific, phenology‐based and spatially informed integrated pest management

Fractional multiwavelet methods for solving spatiotemporal fractional diffusion equations with non-smooth solutions

open access: yesMathematical Modelling and Analysis
This introduces a new method that effectively solves spatiotemporal fractional diffusion equation(FDE) using fractional Lagrange interpolation and fractional multiwavelets. The method effectively addresses situations with non-smooth solutions.

A pilot variational coupled reanalysis based on the CESAM climate model

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

Computing Skinning Weights via Convex Duality

open access: yesComputer Graphics Forum, EarlyView.
We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.
