Research ArticleOpen accessIn the abstractExplainable MedAttn-ResNet50 for Automated Kidney Tumor Classification from CT Images With Grad-CAM VisualizationD. Vetrithangam, Pramod Kumar, Shilpasree S. et al.Kidney tumor classification from CT imaging remains challenging due to CT-specific intensity variations, tumor heterogeneity, and limited clinically meaningful interpretability in existing deep learning models. To address these limitations, we propose an Explainable MedAttn-ResNet50 framework that integrates radiology-driven preprocessing, multi-scale feature extraction, and medical attention mechanisms within a unified architecture. The preprocessing pipeline applies radiology-inspired intensity normalization, contrast enhancement, and … …Journal of Computer Science, Vol. 22, Issue 8 · 13 Aug 2026 · 1,120 accessesView PDFCite
Research ArticleOpen accessIn the abstractMonitoring of Vegetation Degradation in various Landscapes of the Moyinkum Desert, KazakhstanOmirzhan Taukebayev, Bektemir Osmonali, Salavat Duisenbayev et al.This study is devoted to assessing the degree of vegetation degradation in various landscapes of the Moyinkum Desert, taking into account the taxonomic diversity of flora, the structure of phytocenoses, and the agrochemical condition of soils. The aim of the work was to identify areas with signs of disturbance and to analyse the factors determining degradation processes.
