Efficient water management is essential for sustainable agricultural production, particularly in arid and semi-arid regions where water resources are limited. Machine-learning-based irrigation systems can support automated pump-operation decisions using environmental and soil-related sensor data. However, most previous studies have focused on individual machine-learning models, while the application of stacked ensembles to binary irrigation pump-status prediction remains relatively limited. This study proposes a stacking-based framework for predicting irrigation pump operation in an ON/OFF classification setting. The framework uses environmental and soil-related variables, including soil moisture, temperature, humidity, and a numerical time-related feature. Random forest (RF), extreme gradient boosting (XGBoost), and multilayer perceptron models were trained as base learners, and their out-of-fold (OOF) predictions were combined using a logistic-regression meta-learner. The models were evaluated on a held-out test set using accuracy, precision, recall, specificity, and F1-score. The individual models achieved accuracies ranging from 97.34% to 99.95%, with XGBoost providing the best individual performance. The proposed stacking ensemble achieved 99.97% accuracy, 99.94% precision, 100.00% recall, 99.94% specificity, and a 99.97% F1-score. Compared with XGBoost, the ensemble further refined predictive performance, improving accuracy by 0.02 percentage points and F1-score by 0.01 percentage points while achieving complete elimination of false negatives (100.00% recall). These results demonstrate the potential of stacked ensemble learning to improve binary pump-operation prediction and support data-driven irrigation management in water-limited environments.

Ushbu tadqiqotda antropogen transformatsiyaga uchragan Orol dengizi havzasining turli gidrologik va gidrokimyoviy rejimga ega bo‘lgan ichki suv havzalarida chavoq baliq (Rutilus rutilus Linnaeus, 1758)ning zamonaviy tarqalishi, biotopik taqsimoti hamda asosiy biologik ko‘rsatkichlari (chiziqli o‘lchamlari, tana vazni, Fulton semizlik koeffitsiyenti) qiyosiy tahlil qilingan. Tadqiqot materiallari 2021–2025-yillar davomida Aydar-Arnasoy ko‘llar tizimi (Aydarko‘l, Tuzkon) hamda Zarafshon daryosi quyi havzasining qoldiq va kollektor ko‘llaridan (Sho‘rko‘l, Zamonbobo) to‘plangan (). Aniqlanishicha, R. rutilus o‘rganilgan barcha gidrotizimlarda o‘zining yuqori ekologik plastikligini (evrigalinlik va evrifagiya) namoyon etib, ixtiotsenozlarning dominant komponenti bo‘lib qolmoqda. Suvning minerallashuv darajasi 1.4 g/l dan 8.2 g/l gacha bo‘lgan oraliqda populyatsiyalarning o‘sish ko‘rsatkichlari va semizlik parametrlarida statistik jihatdan ishonchli farqlar () aniqlandi. Olingan natijalar ichki suv havzalari bioresurslaridan oqilona foydalanish va aborigen ixtiofauna monitoringini yuritishda ilmiy-amaliy asos bo‘lib xizmat qiladi.

The period from the beginning of the Major Occultation (329 AH) to the establishment of the Safavid state (907 AH) is considered one of the sensitive junctures in the history of Islam and Shi'ism. During this period, the Shi'a faced a crisis of leadership of the Infallible Imam (peace be upon him) and underwent various vicissitudes. However, the numerous obstacles along the way could not prevent Shi'ism from growth and flourishing; rather, it continued its movement with steady steps and was able to extend its influence to various regions. This success after the Major Occultation was the result of several factors, among which the contribution of ethical components is significant. The present study seeks to answer the following question: What were the ethical-political components influencing the growth of Shi'ism from the Major Occultation (329 AH) to the establishment of the Safavid state (907 AH)? A descriptive-analytical examination of the ethics of Shia rulers demonstrates that legalism and the implementation of divine ordinances in society in accordance with the commands of the Shari'a, just behavior, populism, rationalism, and attention to the religious and Shia education of the people by most Shia rulers in the period under discussion were influential in promoting their school of thought and spreading the Shia religion.

This work presents a conceptual framework for an AI-powered multilingual healthcare chatbot designed to improve healthcare accessibility, disease awareness, and public health communication, particularly for rural and underserved communities. The proposed framework integrates Artificial Intelligence (AI), Natural Language Processing (NLP), transformer-based language models, multilingual speech recognition, image-assisted symptom support, and authenticated healthcare information into a unified conversational platform.
The framework supports text, voice, and image-based interactions through familiar communication platforms such as WhatsApp and SMS, enabling users to access reliable healthcare information without requiring dedicated mobile applications. It is designed to reduce language barriers, promote preventive healthcare, and improve access to trusted medical guidance while encouraging timely consultation with healthcare professionals.
This paper discusses the conceptual design, system architecture, methodology, potential applications, advantages, and future scope of the proposed framework. The proposed approach aims to support inclusive digital healthcare by combining multilingual communication, AI-based conversational assistance, and authenticated healthcare information into a scalable and accessible solution.

Background. Conceptual tables and graphic organizers are among the most extensively researched external representations in education, and their effects on pupils are well documented. The preparation of the teachers who design and mediate them has received far less theoretical attention, particularly in primary mother tongue language education.Purpose. The study substantiates the theoretical and methodological foundations for developing pre-service primary school teachers' skills in using conceptual tables and graphic organizers in mother tongue language education.Materials and methods. The study is conceptual and methodological rather than empirical. A purposively assembled corpus of international and national scholarship, prioritising publications from 2020 onwards alongside foundational theoretical works, was examined through theoretical, comparative, document and content analysis, synthesis, generalisation, and pedagogical modelling. Seven theoretical positions were integrated into the analytical framework.Results. The reviewed evidence supports a design-and-mediation rather than a tool-provision reading of visual organisation, and therefore presupposes a teacher-level capability that the literature has not theorised. Visual information organisation is specified as a functional-structural component of primary teachers' methodological competence in mother tongue education, comprising cognitive–knowledge, practical–activity, methodical–pedagogical, and reflective–evaluative blocks ordered by the chain cognitive → practical → methodical → reflective. Its formation is specified through six principles, five stages, and three levels defined by block.Conclusions. The foundations supply an operational design logic that universities can adopt within existing programme structures and that subsequent empirical work can test.
