The construction of these methods is based on the variational iteration approach which provides a systematic framework for formulating efficient and flexible algorithms. The proposed schemes generalize and encompass well-known classical methods such as Newton’s and Halley’s methods, along with their modified versions as special cases. This generality enhances their adaptability to a broader class of nonlinear problems involving both known and unknown multiplicities. To assess the effectiveness of the proposed iterative schemes, extensive numerical experiments are conducted, comparing their convergence speed and accuracy with existing methods. The results demonstrate that the newly developed methods exhibit superior performance in terms of stability, precision, and computational efficiency. Furthermore, to visualize and analyse the global convergence behaviour fractal basin plots are presented. These fractals illustrate the basins of attraction in the complex plane, providing deeper insight into the dynamical behaviour, convergence regions and boundary structures associated with each iterative process.<ul><li><span>•</span><span><div>Developing efficient and flexible iterative methods using the variational iteration method.</div></span></li><li><span>•</span><span><div>Generalizing classical methods to tackle nonlinear problems with known and unknown multiplicity.</div></span></li><li><span>•</span><span><div>Validating performance of various methods through detailed numerical experiments and fractal basin plots.</div></span></li></ul></div></div>","PeriodicalId":18446,"journal":{"name":"MethodsX","volume":"16 ","pages":"Article 103778"},"PeriodicalIF":1.9,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145926358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional boundary mapping methods, such as manual digitization and semi-automated extraction from farm machinery, are labor-intensive and challenging to apply at large scales. Advances in high-resolution land cover data and satellite imagery offer scalable solutions for automated field boundary extraction.

Seasonal composites of Red, Green, and Blue bands were generated at different phenological stages to support segmentation. The method was applied across over 32 million hectares (79 million acres) of cultivated land in the Canadian Prairies, achieving an intersection-over-union (IoU) accuracy of 0.86 compared to manual segmentation. The workflow consists of four main steps: (1) setting the python working environment, (2) seasonal image acquisition and preprocessing using Google Earth Engine via Python API; (3) field boundary segmentation using SAM; and (4) post-processing and feature cleaning using ArcGIS Pro.

This study presents a PRISMA-guided systematic review of empirical, numerical, centrifuge, and field investigations on hybrid slope-stabilization systems. The review advances prior work by explicitly incorporating multi-field coupling and soil–structure interaction (SSI) terms into the search strategy, applying transparent screening and data-extraction procedures supported by a reusable metadata codebook, and conducting cross-study triangulation across field evidence, centrifuge modelling, and 2D/3D numerical analyses. The synthesized evidence shows that hybrid systems can significantly enhance slope performance, with reported improvements of up to ∼45 % in factor of safety and >30 % reduction in settlement, depending on reinforcement configuration, soil conditions, and coupled rainfall–seismic effects.

The NRRM addresses this gap by explaining how viewers attend to, interpret, remember, emotionally connect with, and sometimes resist or contest a remake’s narrative and aesthetic cues. The paper demonstrates the method through a scene-level application of two case studies to show how remakes function simultaneously as mnemonic devices and affective tools.
