An Integrated Climate and Water Stress Index for Index-Based Insurance of Irrigated Agriculture: Development and Validation in the Shu-Talas Water Management Basin, Kazakhstan

In the context of increasing climate variability, the assessment of risks to irrigated agriculture requires a combined consideration of climatic and water management factors. The aim of this study is to develop an Integrated Climate and Water Stress Index (ICWSI) and to assess it...

Adsorption and Photocatalytic Activity of Covalent Organic Frameworks for Environmental Remediation: A Review of Density Functional Theory Studies

The contamination of water resources by heavy metals, radionuclides, and organic pollutants demands efficient materials for water treatment. Covalent organic frameworks (COFs) are promising candidates owing to their tunable porosity and functionalizable frameworks. This review ex...

Changes in the traditional clothing of Kazakhs in the Tarbagatay region between the end of the nineteenth century and the twenty-first century

The Tarbagatay region in eastern Kazakhstan, encompassing the Aksuat, Ayagoz, Makanshy and Urjar districts of the present-day Abay region as well as the Semey area, represents a distinctive cultural space shaped by long-standing interactions among Kazakh, Tatar and Russian popula...

Edge-Based Long-TermAutomated Monitoring of Budgerigar Vocal Activity Using YAMNet

Continuous monitoring of animal behavior may provide quantitative information on responses to environmental changes; however, its application in seismobiological research requires reliable characterization of baseline behavioral variability. This study developed and evaluated an...

Intelligent Hybrid Neuro-Fuzzy Control System for Industrial Bread Baking Ovens

Intelligent control systems can stabilise operational processes and support the development of digital manufacturing in the food industry. This study presents and examines a digital twin of an industrial bread oven with a hybrid neuro-fuzzy controller for temperature and humidity...

Regional Innovation Disparities in Kazakhstan: Input–Output Misalignment in an Official Panel, 2014–2025

How are innovation inputs and measured outputs distributed across the regions of a resource-dependent post-Soviet economy, and how closely do they correspond? We use a balanced official panel of Kazakhstan’s 17 regions for 2014–2025 (204 region–year observations) covering four in...

Testing Carbon-Input Feasibility in RothC Using Paired Soil Resampling over a 20-Year Interval in a Semi-Arid Steppe

Long-term soil organic carbon (SOC) monitoring provides a rare opportunity to test the performance of process-based models against real data. We evaluated RothC using 20 georeferenced soil profiles sampled in 2004 and 2024 in the semi-arid steppe of Central Kazakhstan. We used th...

Genetic and Epigenetic Diversity of Salmonella enterica Isolates from Clinical and Veterinary Sources in Kazakhstan

Salmonella enterica is a major cause of foodborne and invasive infections worldwide. This retrospective study used whole-genome sequencing to compare the genotypes and characterize the genomic diversity of bacterial strains preserved in an archived culture collection, originating...

A Spatial Assessment of the Production and Economic Performance of the Agro-Industrial Complex in the North Kazakhstan Region

Agricultural planning at the district level requires a transparent comparison of investments, production, financial returns, and resource availability. This study evaluates the relative production and economic performance of 13 districts in the North Kazakhstan Region based on se...

Plasma-Assisted and Green Routes to Silicon and Carbon Quantum Dots: A Critical Comparison of Synthesis–Structure–Property Relationships

Silicon quantum dots (SiQDs) and carbon quantum dots (CQDs) are often discussed as related heavy-metal-free luminescent nanomaterials, although the mechanisms governing their formation and emission differ fundamentally. Rather than combining two parallel bodies of literature, thi...

Metal Extraction and Solid-Phase Evolution During Ammoniacal Leaching of Spent LiCoO2 Cathodes

Ammonia leaching constitutes a selective route for the recovery of metals from used lithium-ion batteries, but the relationship between the extraction of metals and the evolution of residues remains insufficiently understood. This study focused on the leaching of used and pretrea...

Data-calibrated cost-aware freight routing in a mixed diesel-electric railway network: a multi-corridor study from Kazakhstan

Rail freight route choice often combines distance, train-formation and operating rules without making the cost effects of heterogeneous traction explicit. This study evaluates a transparent, data-calibrated route-cost framework for strategic planning on Kazakhstan’s mixed diesel-...

The Influence of the Composition of Lead Cakes on the Extraction of Osmium and Rhenium During Their Hydrometallurgical Processing

The processing of lead cakes containing osmium and rhenium is complicated by the significant variability in their elemental and phase compositions. The aim of this study was to determine the effects of lead cake composition on acid consumption and the recovery of Os and Re during...

Identifiability and Conditioning of Flux-Parameter Inversion for the Buckley–Leverett Equation

We analyse inversion of the viscosity ratio M in the Buckley–Leverett equation, distinguishing structural identifiability, observation-operator conditioning, and numerical estimation error. The Riemann solution gives M=4s2−4s from the shock speed s, with relative condition number...

A refined decay condition for a high-contrast sandwich plate subject to antiplane shear

Abstract A three-layered elastic semi-infinite strip subject to antiplane shear is considered. The relative stiffness ratio is assumed to be a small parameter. The so-called decay conditions generalising the Saint-Venant’s principle are studied. A first-order asymptotic correctio...

Effectiveness of early initiation of idursulfase in infants and very young children with mucopolysaccharidosis II: a retrospective chart review in siblings

Introduction Enzyme replacement therapy (ERT) with intravenous idursulfase is the standard of care for patients with mucopolysaccharidosis II (MPS II; Hunter syndrome). Data are limited for children aged ≤12 months. This retrospective study evaluated outcomes with early ERT. Meth...

A geometric data augmentation and mechanism modeling framework for class-imbalanced wind turbine fault diagnosis

With the growing deployment of wind energy, reliable fault diagnosis of wind turbines (WTs) is increasingly important for sustainable operation and maintenance. However, supervisory control and data acquisition (SCADA) system data are often characterized by severe class imbalance...

Waste-Derived Natural Polymer Biosorbents for Toxic Metal Ions: Structure–Sorption Relationships, Modification Strategies, and Prospects for Solid-Phase Sensing

Waste-derived natural polymers offer a route to low-cost sorbents for toxic metal ions, but reported performance is difficult to compare because precursor composition, polymer processing, modification, and experimental conditions vary widely. This critical review examines silk fi...

Fully Complementary Interactions of Human mRNA Genes with miRNAs from NCBI Database

miRNA has been studied for over 30 years, but the interaction of miRNA with mRNA has not been sufficiently studied to date. Problems in this area of research include the lack of adequate methods for predicting the characteristics of miRNA-mRNA interactions, and wet lab experiment...
