Seismic microzonation for Almaty city for the first time use probabilistic approach and hazard is expressed in terms of not only macroseismic intensity,but also Peak Ground Acceleration(PGA).To account for the effects of local soil conditions,the continual approach proposed by A.S.Aleshin[1,2]was used,in which soil coefficients are a function of the continuously changing seismic rigidity.Soil coefficients were calculated using the new data of geological and geophysical surveys and findings of previous geotechnical studies.The used approach made it possible to avoid using soil categories and a jump change in characteristics of soil conditions and seismic impact.The developed seismic microzonation maps are prepared for further introduction into the normative documents of the Republic of Kazakhstan. 展开更多

Myocardial infarction(MI)is one of the leading causes of death globally among cardiovascular diseases,necessitating modern and accurate diagnostics for cardiac patient conditions.Among the available functional diagnostic methods,electrocardiography(ECG)is particularly well-known for its ability to detect MI.However,confirming its accuracy—particularly in identifying the localization of myocardial damage—often presents challenges in practice.This study,therefore,proposes a new approach based on machine learning models for the analysis of 12-lead ECG data to accurately identify the localization of MI.In particular,the learning vector quantization(LVQ)algorithm was applied,considering the contribution of each ECG lead in the 12-channel system,which obtained an accuracy of 87%in localizing damaged myocardium.The developed model was tested on verified data from the PTB database,including 445 ECG recordings from both healthy individuals and MI-diagnosed patients.The results demonstrated that the 12-lead ECG system allows for a comprehensive understanding of cardiac activities in myocardial infarction patients,serving as an essential tool for the diagnosis of myocardial conditions and localizing their damage.A comprehensive comparison was performed,including CNN,SVM,and Logistic Regression,to evaluate the proposed LVQ model.The results demonstrate that the LVQ model achieves competitive performance in diagnostic tasks while maintaining computational efficiency,making it suitable for resource-constrained environments.This study also applies a carefully designed data pre-processing flow,including class balancing and noise removal,which improves the reliability and reproducibility of the results.These aspects highlight the potential application of the LVQ model in cardiac diagnostics,opening up prospects for its use along with more complex neural network architectures. 展开更多

Deep learning now underpins many state-of-the-art systems for biomedical image and signal processing,enabling automated lesion detection,physiological monitoring,and therapy planning with accuracy that rivals expert performance.This survey reviews the principal model families as convolutional,recurrent,generative,reinforcement,autoencoder,and transfer-learning approaches as emphasising how their architectural choices map to tasks such as segmentation,classification,reconstruction,and anomaly detection.A dedicated treatment of multimodal fusion networks shows how imaging features can be integrated with genomic profiles and clinical records to yield more robust,context-aware predictions.To support clinical adoption,we outline post-hoc explainability techniques(Grad-CAM,SHAP,LIME)and describe emerging intrinsically interpretable designs that expose decision logic to end users.Regulatory guidance from the U.S.FDA,the European Medicines Agency,and the EU AI Act is summarised,linking transparency and lifecycle-monitoring requirements to concrete development practices.Remaining challenges as data imbalance,computational cost,privacy constraints,and cross-domain generalization are discussed alongside promising solutions such as federated learning,uncertainty quantification,and lightweight 3-D architectures.The article therefore offers researchers,clinicians,and policymakers a concise,practice-oriented roadmap for deploying trustworthy deep-learning systems in healthcare. 展开更多

This study explores the cultural and value foundations of the educational goals of higher education in Kazakhstan and China.Based on the historical development and cultural traditions of the two countries,this study compares the similarities and differences of the educational goals of the two countries through qualitative literature content analysis.Both countries have taken“modernization and internationalization”as one of the core development directions of higher education development,but China’s educational philosophy is rooted in Confucianism and socialist core values,emphasizing country and collectivism;while Kazakhstan,based on neoliberal orientation,draws on the European education framework,gradually integrates multicultural concepts,emphasizes national identity and attaches importance to students’individual development.This study uses Hofstede’s cultural dimensions and postcolonial education theory to explore how different nation-building narratives affect the educational goals of higher education.By comparing value systems,institutional logics,and student training models,it helps to understand how the educational systems of the“Global South”countries seek a balance between international standards and local cultural identity.It provides inspiration for the development of education based on culture and mutual reference under the global education trend,and provides a comparative education perspective for reform localization. 展开更多

BACKGROUND For over half a century,the administration of maternal corticosteroids before anticipated preterm birth has been regarded as a cornerstone intervention for enhancing neonatal outcomes,particularly in preventing respiratory distress syndrome.Ongoing research on antenatal corticosteroids(ACS)is continuously refining the evidence regarding their efficacy and potential side effects,which may alter the application of this treatment.Recent findings indicate that in resource-limited settings,the effectiveness of ACS is contingent upon meeting specific conditions,including providing adequate medical support for preterm newborns.Future studies are expected to concentrate on developing evidence-based strategies to safely enhance ACS utilization in low-and middle-income countries.AIM To analyze the clinical effectiveness of antenatal corticosteroids in improving outcomes for preterm newborns in a tertiary care hospital setting in Kazakhstan,following current World Health Organization guidelines.METHODS This study employs a comparative retrospective cohort design to analyze single-center clinical data collected from January 2022 to February 2024.A total of 152 medical records of preterm newborns with gestational ages between 24 and 34 weeks were reviewed,focusing on the completeness of the ACS received.Quantitative variables are presented as means with standard deviations,while frequency analysis of qualitative indicators was performed using Pearson'sχ^(2) test(χ^(2))and Fisher's exact test.If statistical significance was identified,pairwise comparisons between the three observation groups were conducted using the Bonferroni correction.RESULTS The obtained data indicate that the complete implementation of antenatal steroid prophylaxis(ASP)improves neonatal outcomes,particularly by reducing the frequency of birth asphyxia(P=0.002),the need for primary resuscitation(P=0.002),the use of nasal continuous positive airway pressure(P=0.022),and the need for surfactant replacement therapy(P=0.038)compared to groups with incomplete or no ASP.Furthermore,complete ASP contributed to a decrease in morbidity among preterm newborns(e.g.,respiratory distress syndrome,intrauterine pneumonia,cerebral ischemia,bronchopulmonary dysplasia,etc.),improved Apgar scores,and reduced the need for re-intubation and the frequency of mechanical ventilation.However,it was associated with an increased incidence of uterine atony in postpartum women(P=0.0095).CONCLUSION In a tertiary hospital setting,the implementation of ACS therapy for pregnancies between 24 and 34 weeks of gestation at high risk for preterm birth significantly reduces the incidence of neonatal complications and related interventions.This,in turn,contributes to better outcomes for this cohort of children.However,the impact of ACS on maternal outcomes requires further thorough investigation. 展开更多

Chronic suppurative otitis media(CSOM)is a prevalent condition in otolaryngology with significant medical and social implications,including hearing loss and severe intracranial complications.This article discusses the challenges in diagnosing cholesteatoma,a common complication of CSOM,particularly when using computed tomography(CT)and magnetic resonance imaging(MRI).We present three clinical cases where MRI,particularly in the non-EPI diffusion-weighted imaging(DWI)and apparent diffusion coefficient(ADC)modes,effectively identified the presence and extent of cholesteatoma that CT could not reliably distinguish due to overlapping features with other soft tissue formations.The high sensitivity of MRI,highlight its value in both primary diagnosis and assessment of recurrence.Our findings advocate for the incorporation of MRI into the diagnostic protocols for CSOM in the Republic of Kazakhstan,emphasizing the need for reliable epidemiological data to inform future research and prevent potential intracranial complications. 展开更多

This paper examines the application of the Verkle tree—an efficient data structure that leverages commitments and a novel proof technique in cryptographic solutions.Unlike traditional Merkle trees,the Verkle tree significantly reduces signature size by utilizing polynomial and vector commitments.Compact proofs also accelerate the verification process,reducing computational overhead,which makes Verkle trees particularly useful.The study proposes a new approach based on a non-positional polynomial notation(NPN)employing the Chinese Remainder Theorem(CRT).CRT enables efficient data representation and verification by decomposing data into smaller,indepen-dent components,simplifying computations,reducing overhead,and enhancing scalability.This technique facilitates parallel data processing,which is especially advantageous in cryptographic applications such as commitment and proof construction in Verkle trees,as well as in systems with constrained computational resources.Theoretical foundations of the approach,its advantages,and practical implementation aspects are explored,including resistance to potential attacks,application domains,and a comparative analysis with existing methods based on well-known parameters and characteristics.An analysis of potential attacks and vulnerabilities,including greatest common divisor(GCD)attacks,approximate multiple attacks(LLL lattice-based),brute-force search for irreducible polynomials,and the estimation of their total number,indicates that no vulnerabilities have been identified in the proposed method thus far.Furthermore,the study demonstrates that integrating CRT with Verkle trees ensures high scalability,making this approach promising for blockchain systems and other distributed systems requiring compact and efficient proofs. 展开更多

While automatic image captioning systems have made notable progress in the past few years,generating captions that fully convey sentiment remains a considerable challenge.Although existing models achieve strong performance in visual recognition and factual description,they often fail to account for the emotional context that is naturally present in human-generated captions.To address this gap,we propose the Sentiment-Driven Caption Generator(SDCG),which combines transformer-based visual and textual processing withmulti-level fusion.RoBERTa is used for extracting sentiment from textual input,while visual features are handled by the Vision Transformer(ViT).These features are fused using several fusion approaches,including Concatenation,Attention,Visual-Sentiment Co-Attention(VSCA),and Cross-Attention.Our experiments demonstrate that SDCG significantly outperforms baseline models such as the Generalized Image Transformer(GIT),which achieves 82.01%,and Bootstrapping Language-Image Pre-training(BLIP),which achieves 83.07%,in sentiment accuracy.While SDCG achieves 94.52%sentiment accuracy and improves scores in BLEU and ROUGE-L,the model demonstrates clear advantages.More importantly,the captions aremore natural,as they incorporate emotional cues and contextual awareness,making them resemble those written by a human. 展开更多

The increasing atmospheric CO_(2)concentration linked to human activity results in global warming by the greenhouse effect.This anthropogenic CO_(2)may be sequestrated into geological formations,e.g.,porous basalts,saline aquifers,depleted oil or gas reservoirs,and unmineable coal seams.Furthermore,carbon capture,utilization,and storage(CCUS)methods are an acceptable and sustainable technology to meet the goals of the Paris Agreement,in which Kazakhstan is expected to reduce greenhouse gas emissions by 25%compared with the 1990 level.Unmineable coal seams are an attractive option among all geostorage solutions,as CO_(2)sequestration in coal comes with an income stream via enhanced coalbed methane(ECBM)recovery.This paper identifies four carboniferous coal formations,namely Karagandy,Teniz-Korzhinkol,Ekibustuz,and Chu coal basins of Kazakhstan,as CO_(2)geostorage solutions for their unmineable coal seams.The ideal depth of CO_(2)storage is identified as 800 m to ensure the supercritical state of CO_(2).However,the Ekibustuz coal basin fails to meet the required depth of 800 m in its unmineable coal seams.The conventional formula for calculating CO_(2)storage in coal basins has been modified,and a new formula has been proposed for assessing the CO_(2)storage potential in a coal seam.The CO_(2)storage capacities of unmineable coal seam of these coal basins are 24.60 Bt,0.61 Bt,14.02 Bt,and 5.42 Bt,respectively.The Langmuir volume of the coal fields was calculated using the proximate analysis of coalfields and found to vary between 36.42 and 98.90 m3/ton.This paper is the first to outline CO_(2)storage potential in Kazakhstani coal basins,albeit with limited data,along with a detailed geological and paleographic review of the carboniferous coalfields of Kazakhstan.A short overview of the CO_(2)-ECBM process was also included in the paper.Instead of any experimental work for CO_(2)storage,this paper attempts to present the CO_(2)storage capacity of carboniferous coal formation using the modified version of previously determined formulas for CO_(2)storage. 展开更多

Understanding migration patterns and spatial connectivity is crucial for conserving long-distance migratory birds. While satellite telemetry has advanced the study of large gulls, Pallas's Gull (Ichthyaetus ichthyaetus) remains relatively understudied, with limited data on its migration routes and habitat use, particularly in Central Asia. This study integrates 684 ring recoveries (1968–2024) and GPS tracking data to analyze the migration ecology of individuals breeding at Alakol Lake, Kazakhstan. Ring recoveries confirm migratory connectivity across Kazakhstan, Russia, Uzbekistan, Turkmenistan, Iran, and Pakistan, with wintering records as far as India, Kuwait, Bangladesh, and Ethiopia. GPS tracking of a single individual (June 2020–August 2021) revealed a migration route from Alakol Lake to the Arabian Sea, with key stopovers at Zaisan Lake, Balkhash Lake, the Aral Sea, Aydar Lake, and the Amu Darya River. Notably, a post-breeding northward dispersal to Zaisan Lake and southern Russia was identified before the southward migration commenced. These findings highlight the significance of Kazakhstan's lakes as breeding and migratory hubs and the need to protect critical stopover sites in Central Asia. Given increasing anthropogenic pressures on wetland habitats, this research provides essential baseline data for conservation planning and enhances the broader understanding of gull migration ecology. 展开更多

Local cattle breeds play a critical role in breeding programs due to their genetic adaptations to diverse environmental conditions.However,the genomic architecture of local cattle breeds in Kazakhstan remains largely unexplored.This study utilized whole-genome sequencing data from Kazakh cattle to elucidate their genetic composition,uncovering three primary ancestral components:European,Eurasian,and East Asian taurine.The East Asian taurine lineage likely represents the earliest genetic contribution to Kazakh cattle but was largely replaced by subsequent waves of cattle migrations across Eurasia,leaving only a minor genetic signature in the current cattle population.In contrast,Eurasian taurine ancestry predominated in the Alatau and Kazakh local breeds,while the European taurine component was most prevalent in Kazakh white-headed cattle,consistent with their documented breeding history.Kazakh cattle exhibited higher genetic diversity and lower inbreeding coefficients compared to European commercial breeds,reflecting reduced exposure to intense artificial selection.A strong selection signal was identified on chromosome 6 at a locus encompassing PDGFRA,KIT,and KDR,which may be associated with the white-headed pigmentation characteristic of Kazakh white-headed cattle.Additional genes under selection were linked to lipid metabolism(IRS1,PRKG1,and ADCY8),meat production traits(KCNMA1,PDGFRA,HIF1A,and ANTXR1),and dairy production(ATP2B1,DHX15,FUK,NEGR1,CCDC91,COG4,and PTK2B).This study represents the first comprehensive analysis of nuclear genome data from local Kazakh cattle.It highlights the impact of historical cattle migrations across Eurasia on their genetic landscape and identifies key genomic regions under selection.These findings advance our understanding of the evolutionary history of cattle and offer valuable genetic resources for future breeding strategies. 展开更多

The article presents the results of in-kind measurements and numerical modeling of the formation of water characteristics in the Kama River,which is used for technical water supply in the production of potash fertilizers.In the warm season,risks arise that threaten the sustainability of the water supply.It was found that in the summer,when the studied section of the Kama River is backed up by the KamaHydroelectric Power Station,there is a significant decrease in flow rates,which leads to vertical stratification of water properties.This,in turn,significantly limits the possibilities of using water fromthe bottom zone.Under conditions of significant water discharge from the reservoir,this section has river conditions with significantly higher flow rates.Under such conditions,intense vertical mixing of water masses occurs,which improves the consumer properties of water necessary for sustainable water supply.The results of numerical modeling carried out within the framework of the three-dimensional approach confirmed this conclusion.It is shown that with an increase in the flow rate in the channel near thewater intake,the concentration of salts decreases,which is an important factor in ensuring high-quality water supply. 展开更多

Wireless Sensor Networks(WSN)have gained significant attention over recent years due to their extensive applications in various domains such as environmentalmonitoring,healthcare systems,industrial automation,and smart cities.However,such networks are inherently vulnerable to different types of attacks because they operate in open environments with limited resources and constrained communication capabilities.Thepaper addresses challenges related to modeling and analysis of wireless sensor networks and their susceptibility to attacks.Its objective is to create versatile modeling tools capable of detecting attacks against network devices and identifying anomalies caused either by legitimate user errors or malicious activities.A proposed integrated approach for data collection,preprocessing,and analysis in WSN outlines a series of steps applicable throughout both the design phase and operation stage.This ensures effective detection of attacks and anomalies within WSNs.An introduced attackmodel specifies potential types of unauthorized network layer attacks targeting network nodes,transmitted data,and services offered by the WSN.Furthermore,a graph-based analytical framework was designed to detect attacks by evaluating real-time events from network nodes and determining if an attack is underway.Additionally,a simulation model based on sequences of imperative rules defining behaviors of both regular and compromised nodes is presented.Overall,this technique was experimentally verified using a segment of a WSN embedded in a smart city infrastructure,simulating a wormhole attack.Results demonstrate the viability and practical significance of the technique for enhancing future information security measures.Validation tests confirmed high levels of accuracy and efficiency when applied specifically to detecting wormhole attacks targeting routing protocols in WSNs.Precision and recall rates averaged above the benchmark value of 0.95,thus validating the broad applicability of the proposed models across varied scenarios. 展开更多
