Growing Si–Si 1− x Ge x –(Ge 2 ) 1− y (GaAs) y structures in a single technological cycle

Abstract The technology of creating Si–Si 1− x Ge x –(Ge 2 ) 1− y (GaAs) y heterostructures on a single-crystal substrate has been tested. The functional layers are deposited from a limited tin melt solution in a single process cycle, which is optimal from the application’s point...

Critical Markov Branching-Immigration Systems: Complete Classification of the State Space and Exact Rates of Convergence

We study a critical homogeneous continuous-time Markov branching-immigration system whose offspring and immigration generating functions regularly vary at point 1 of orders 1+ν and δ with ν,δ∈(0,1]. The slowly varying factors are controlled through their index functions, which ca...

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...

Evaluating Well Stimulation in Carbonates: Rapid Skin Factor Prediction Using Machine Learning

ABSTRACT Accurate prediction of the poststimulation skin factor ( S ) is vital for optimizing productivity in carbonate reservoirs. Conventional approaches, such as well‐test analysis, are costly and time‐consuming, limiting their use for real‐time decision‐making. This study int...

TERRITORIAL DISPARITIES IN EMPLOYMENT EFFICIENCY IN KHOREZM REGION: ASSESSMENT AND POLICY DIRECTIONS

Employment efficiency across 13 territories of the Khorezm Region is assessed using five criteria. Criteria K1–K4 are calculated based on 39 territory-year observations for 2022–2024, while K5 reflects employment dynamics over 2021–2024. The findings indicate that interterritoria...

Blue carbon ecosystems under pollution stress: Impacts and integrated carbon‐pollution monitoring

Abstract Coastal blue carbon ecosystems, including mangroves, seagrass meadows, and salt marshes, are globally important carbon sinks because they store organic carbon in vegetation biomass and waterlogged sediments over long timescales. However, nutrient enrichment, heavy metals...
