Cradle-to-gate life cycle assessment of pasteurized milk production in Uzbekistan identifies environmental hotspots and improvement opportunities

Dairy production is an important component of Uzbekistan's food system but is associated with environmental burdens. This study presents a cradle-to-gate life cycle assessment (LCA) of pasteurized milk production in Uzbekistan to quantify environmental impacts, identify hotspots,...

Well-posedness of difference schemes for elliptic NBVPs in holder spaces with weights

Nonlocal boundary value problems for elliptic equations arise in various mathematical models and applications, where classical local boundary conditions are insufficient to describe the underlying phenomena. Developing accurate and stable numerical methods for such problems is th...

DNA barcoding reveals genetic divergence and phylogenetic relationships of Scymnus species (Coleoptera: Coccinellidae) from Uzbekistan

Ladybird beetles of the genus Scymnus (Coleoptera: Coccinellidae) are key predators in agroecosystems, but species-level identification remains challenging due to high morphological similarity among closely related taxa. Molecular data for Central Asian populations are scarce, li...

Microbes in the dust: The ecology of arid soil microbiomes

Drylands now cover approximately 45% of Earth's terrestrial surface and are expanding under climate change, yet the microbial communities inhabiting these vast regions remain poorly integrated into ecosystem models. This review synthesizes current knowledge on arid soil microbiom...

Structure–property relationships in a cobalt(II) sulfonamide complex: crystallographic, Hirshfeld surface, spectroscopic, docking and antibacterial investigations

Sulfonamide-based metal complexes remain of interest because metal coordination can modify their electronic structure and biological properties. A cobalt(II) complex, bis[4-aminobenzenesulfonamide]bis(dimethylformamide)diaqua-cobalt(II) nitrate (Co-ABS-DMF), was synthesized and i...

PUBLIC TRUST AND EXECUTIVE ACCOUNTABILITY: PRIORITIES FOR PARTICIPATORY BUDGETING AT A NEW STAGE OF DEVELOPMENT

This article examines the significance and practical outcomes of the participatory budgeting mechanism, using Tashkent Region as a case study. Particular attention is paid to the implementation of selected projects, including opportunities to improve implementation timelines and...

Extreme-Tail Radial Differentiation in HST Chromosome Maps of Galactic Globular Clusters: A Link to Central Structural State

Chromosome maps (ChMs) reveal multiple stellar populations in globular clusters (GCs), but radial trends can depend on how overlapping structures are partitioned. We analyse 56 Galactic GCs with Hubble Space Telescope UV Globular Cluster Survey (HUGS) photometry, separating the s...

THE ERROR FUNCTIONAL OF A LOCAL CUBIC-SPLINE QUADRATURE FORMULA FOR FOURIER-TYPE INTEGRALS: PEANO REPRESENTATION, OPTIMAL CONSTANTS AND CONVERGENCE CLASSES

The error of the local interpolating cubic-spline quadrature formula for Fourier-type integrals is studied as a bounded linear functional. Its Peano kernel of order three is obtained in closed form. This yields a pointwise estimate that is sharp on functions with bounded third de...

Phenotypic and Molecular Characterization of Winter Wheat Genotypes for Grain Yield, Quality Traits, and HMW Glutenin Subunits

High grain yield (GY) and improved quality, including the presence of high-molecular-weight glutenin subunits (HMW-GS), determine the commercial success of a wheat (Triticum aestivum L.) variety. A field study was conducted in 2021 and 2022 in Kibray, Uzbekistan, using 100 winter...

First Report of Apple Anthracnose Caused by Colletotrichum fructicola in Uzbekistan

Apple (Malus domestica Borkh.) is an important fruit crop in Uzbekistan. Colletotrichum species are important apple pathogens worldwide, and C. gloeosporioides was recently reported to cause bitter rot of apple in Uzbekistan (Sherimbetov et al. 2026). In September 2025, symptomat...

AN AUTOMATIC SPEECH ASSESSMENT ALGORITHM ADAPTING TO THE PRONUNCIATION CHARACTERISTICS OF CONVICTED PERSONS

A safety-constrained speaker-adaptive algorithm is proposed to separate stable acoustic speaker properties from actual foreign-language pronunciation competence. Two to six unlabeled enrollment utterances estimate baseline F0, timbre, habitual rate, and channel. A small residual...

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...

Positive Solutions of a Nonlinear System Characterizing Gibbs Measures in Hard-Core SOS Models on Cayley Trees

We study the $$m$$ -state $$p$$ -Solid-on-Solid model with $$p = \infty$$ on Cayley trees of order $$k \geq 2$$ . We derive a system of functional equations whose solutions correspond to (splitting) Gibbs measures for the model. For cases $$m=2,3$$ we identify conditions under wh...

Hawking Radiation from Non-minimal Einstein--Yang--Mills Black Holes

Abstract We study Hawking emission from the regular magnetic black hole of non-minimal Einstein--Yang--Mills theory. The geometry is supported by a Wu--Yang charge whose Yang--Mills field couples directly to curvature through the non-minimal susceptibility tensor. This coupling r...

Agile project management capability enhances sustainable performance through the sequential mediation of agile leadership and strategic agility

Abstract Organizations face increasing pressure to achieve sustainable performance while remaining competitive in volatile environments. Although agility is widely recognized as being associated with organizational responsiveness, limited research explains how agile project manag...
