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...

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...

Inverse Kernel Identification in a Time‐Fractional Integro‐Differential Equation

ABSTRACT This article investigates a fractional diffusion‐wave model incorporating memory effects. We first analyze the direct problem and establish the existence, uniqueness, and regularity of its solution under suitable conditions. The primary focus is on an inverse problem, in...

A Cu(II) complex-driven supramolecular array: synthesis, crystal structure, Hirshfeld surface analysis and application in dyes adsorption

Using benzilic acid (BA) and 1-Methylimidazole (1-Me-Imi) ligands, a new Cu(II) complex is prepared, formulated as, [Cu(BA)2(1-Me-Imi)2(H2O)] (1). In the structure, the Cu(II) metal ion adopted a distorted square-pyramidal geometry, completed by two BA ligands, two 1-Me-Imi ligan...

Bony labyrinth taxonomic identification and long-term evolution of livestock in the Southwest and Central Asia

Abstract Southwest and Central Asia were pivotal regions for the domestication and dispersal of domestic herbivores. Here we investigate long-term variation in bony labyrinth morphology of domestic bovids (sheep, goats and cattle) across the last 10 000 years. We focused on the o...

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...

Interpretable surrogate-assisted scheduling of solar thermochemical hydrogen production in hydrogen refueling-integrated energy systems

Solar thermochemical hydrogen production converts intermittent solar energy into storable clean fuel, but dynamic control of the process remains a challenge. This study proposes an interpretable surrogate-assisted scheduling framework for meeting users’ diverse energy needs in a...

A SEMI-MARKOV–HAWKES FRAMEWORK FOR MODELING SELF-ORGANIZING TRADING ACTIVITY

This study develops a combined Semi-Markov–Hawkes framework for describing the temporal organization of trading activity in a market. The proposed framework treats market behavior as a sequence of discrete events while distinguishing between two mechanisms that are often modeled...

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...

Biobased Polymer Microcapsules with Controlled PCM Retention and Cu2O Surface Functionalization for Thermal and Environmental Applications

Abstract Biobased polymer microcapsules combining thermal energy storage and surface reactivity are of interest for advanced coating applications. In this work, microcapsules encapsulating capric acid (CA) were prepared via suspension polymerization using cinnamyl methacrylate (C...

Status and ontogenetic structure of Codonopsis bactriana (Campanulaceae) in southwestern Uzbekistan

Codonopsis bactriana F.O. Khass., U. Kodyrov & A. Myrz. is a rare endemic medicinal species distributed in the mountainous regions of southwestern Uzbekistan. The present study aimed to assess the current status and ontogenetic structure of natural populations of C. bactriana und...

Investigation of Stress Redistribution Within the Host Rock Mass During Underground Mining Operations

The article presents the results of a systematic investigation of stress redistribution and the formation of stress concentration and relaxation zones in the rock mass surrounding underground mine workings under the influence of mining operations. The study was conducted consider...

Immunogenetic determinants of influenza B virus susceptibility and vaccine response: current evidence, gaps, and future directions

Influenza B virus (IBV) remains an important but comparatively underexamined contributor to seasonal influenza burden, particularly in children, adolescents, and older adults. Although IBV lacks the broad animal reservoir and pandemic potential of influenza A virus, its epidemiol...

Solvothermal synthesis and multifunctional characterization of a two-dimensional Mn(II) coordination polymer with dibromoterephthalate linkers: Dielectric, BET, and hirshfeld surface studies

A new two-dimensional Mn(II)-based coordination polymer, poly[(μ 2 -2,5-dibromobenzene-1,4-dicarboxylato-κ 2 O:O′)bis(μ 2 -formato-κ 2 O:O′)bis(N,N-dimethylformamide-κO)dimanganese(II)] ([Mn 2 (Br 2 BDC)(Fo) 2 (DMF) 2 ] n ), was synthesized solvothermally at 150 °C for 24 h and o...
