Express method for determining power of equivalent dose in radiation-contaminated territories of radioactive tailings storage facilities Operation of radiation-hazardous facilities, such as tailings facilities of the former uranium production of the Prydniprovsky Chemical Plant (PСP, Ukraine), with buildings, structures, observation points, communications, technological equipment, etc. located on their territory, is impossible without a system of physical protection and radiation monitoring. Operation of such facilities in peacetime allows for fairly rapid data collection in the operating mode at the radiation-hazardous facility itself using the method of walking gamma imaging on the perimeter of the tailings storage facility. In conditions of martial law and under certain restrictive circumstances, it is not possible to go directly to the industrial site and conduct full-scale measurements. For this, express methods of mathematical forecasting can be used. Based on the conducted research, the dynamics of observations is calculated, and the predictive model allows determining the regulated radiation parameters (RRP), one of which is the equivalent dose rate, without using radiation control devices with specialists who will conduct measurements. For ten years, the actual values of radiation doses to personnel at the tailings storage facilities of the former uranium production of the PCP were determined. The article presents the developed universal mathematical model for determining the equivalent dose rate of gamma radiation for personnel conducting one-time measurements at a radiation-hazardous facility. The developed mathematical model for measuring the equivalent dose rate values is used for 2D modeling in places where dusty particles with radionuclides settled from the leeward side in the summer in places where the tailings mirror surface decreases. This makes it possible to predict the further radiation situation that will occur in the coming years and improve the system for calculating the total effective dose to a person.

ANALYSIS OF THE CRYSTAL LATTICE AND BAND STRUCTURE OF BI₂TE₃ AS A MATERIAL FOR THERMOELECTRIC AND SPINTRONIC DEVICES This study presents a comprehensive theoretical and experimental examination of the atomic bonding nature and electronic structure of bismuth telluride (Bi₂Te₃), a well-known layered thermoelectric semiconductor. Particular attention is given to its trigonal crystal symmetry, the role of spin-orbit interactions in shaping its band topology, and the significance of weak Van der Waals forces between layers. The bonding types between Bi and Te atoms are thoroughly analyzed using the frameworks of Mooser-Pearson, Lagrenaudie, and Drabble-Goodman. It is shown that structural changes, especially at 60° twin boundaries, can significantly modify the local electronic states and, consequently, the material’s transport and optical performance. These insights may inform the design of advanced thermoelectric and spintronic devices based on Bi₂Te₃.

Design and validation of a robust stability-indicating reversed-phase HPLC method for quantification of mesalamine in formulated drug products A reliable and sensitive RP-HPLC method was developed and validated for the accurate quantification of mesalamine in bulk and formulated pharmaceutical products. The analysis was carried out on a C18 column (150 mm × 4.6 mm, 5 μm) using a mobile phase of methanol: water (60:40 v/v), with a flow rate of 0.8 mL/min, and UV detection at 230 nm. Methanol: water (50:50 v/v) was used as the diluent. The method demonstrated excellent linearity across the concentration range of 10-50 µg/mL (y = 173.53x - 2435.64, R² = 0.9992), high accuracy with recoveries between 99.05% and 99.25% (%RSD < 0.32%), and outstanding precision with intra- and inter-day %RSD values below 1%. Robustness was confirmed under slight method variations (%RSD < 2%), and LOD and LOQ were found to be 0.22 µg/mL and 0.68 µg/mL, respectively. Forced degradation studies under acidic, basic, oxidative, thermal, and photolytic stress confirmed the method's specificity and stability-indicating capability. Assay of a commercial mesalamine tablet (Mesacol<sup>®</sup>, 800 mg label claim) showed a recovery of 99.91%, validating the method's applicability for routine quality control and regulatory compliance.

Developing JMP and VBA Add-Ins for Finite Mixture Modeling of Cotton Fiber Length Distribution In this study, software add-ins were developed and presented to allow data processing and statistical analysis of the unique shape of cotton fiber length distribution. The approach uses VBA coding in Excel to process the data, as well as the JMP 14-17 application and add-in builder tools to fit finite mixture models to empirical fiber length distributions. The resulting model derives a parametric expression for the fiber length probability density function. The analysis add-in was applied and validated on a wide range of empirical length distributions and proved to parameterize the complex distribution patterns with an excellent goodness of fit. Both tools were compiled into installable add-ins that extended the capabilities of MS Excel for the processing of AFIS distribution reports and the statistical toolbox of JMP using the Application Builder JSL coding. Installable add-ins, along with a user manual, are available for download by cotton researchers.

Exploring the Role of Magic Angle Graphene Superconductivity in Advancing Quantum Computing Magic-angle twisted bilayer graphene (MATBG) has emerged as a highly tunable platform for studying strongly correlated electronic phenomena, including unconventional superconductivity. This material exhibits flat electronic bands at specific “magic” twist angles, leading to enhanced electron-electron interactions and a rich phase diagram featuring insulating and superconducting states. This review explores the structural and electronic properties of MATBG, superconducting mechanisms, and potential applications in quantum computing. We discuss how its gate-tunable superconductivity and high level of material purity may help mitigate decoherence in superconducting qubits. Comparisons with other superconductors highlight its unique position in the Uemura plot, aligning with unconventional high-temperature superconductors. Despite limitations such as low critical temperatures, MATBG offers promising pathways toward advanced quantum electronic devices.

An in-depth study of the exotic whiteflies in India's coconut ecosystems: A bibliometric analysis and approaches to their management Coconut trees are constantly threatened by various insect pests, with invasive whiteflies proving particularly harmful. Species such as the rugose spiralling Whitefly (Aleurodicus rugioperculatus), Bondar's nesting whitefly (Paraleyrodes bondari), Nesting whitefly (Paraleyrodes minei) and Palm infesting whitefly (Aleurotrachelus atratus) are severely impacting coconut production in tropical and subtropical regions. These whiteflies damage palms by feeding on sap, disrupting nutrient flow and causing yellowing leaves and premature leaf drop. This weakens the palms, making them more vulnerable to diseases. The honeydew they produce encourages the growth of sooty mould, which blocks sunlight and further hampers photosynthesis. These whiteflies are identifiable by their waxy secretions and distinctive spiralling egg-laying patterns. Their ability to affect various hosts, including ornamental plants and crops, complicates control efforts, facilitating their spread. Natural predators, such as parasitoid wasps from the Encarsia and Eretmocerus genera, help control whitefly populations by targeting eggs and nymphs. Sustainable pest management relies on an integrated pest management (IPM) approach, which combines biological control, regular monitoring, cultural practices like pruning and sanitation and the careful use of chemical insecticides. Adopting a robust IPM strategy is key to controlling whitefly infestations, reducing pest resurgence and ensuring coconut palms' long-term health and productivity while maintaining ecosystem balance and sustainability. A bibliometric analysis using the Bibliometrix R package and VOSviewer (version 1.6.20) has been conducted to assess research trends and identify knowledge gaps.

Ethyl Linoleate Ameliorates Synovial Cell Proliferation and Inflammatory Cell Infiltration in Rheumatoid Arthritis Through DKK1/Wnt‐OPG Signal Axis and Autophagy Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease affecting synovial joints. Jinwu Jiangu Capsules (JJC) has been shown to be effective in treating RA. However, the primary active components and the underlying molecular mechanisms of JJC in RA treatment remain unclear. This study investigates how the monomers of JJC regulate the DKK1/Wnt-OPG signaling axis and autophagy in RA, both in vivo and in vitro. Evaluate the antiarthritis effects of JJC using a Type II collagen-induced arthritis (CIA) rat model. Histopathological analysis is conducted using HE staining, while qPCR, Western blot, ELISA, and GFP-LC3 are used to assess the DKK1/Wnt-OPG signaling pathway and autophagy status. Key components of the capsule are identified through network pharmacology. The effects of these components on osteoblasts are evaluated using CCK-8, alizarin red staining, ALP activity assay, EdU staining, MDC detection, and TRAP staining. JJC effectively reduced the expression of DKK1, RANKL, β-catenin, and p-β-catenin, while increasing the levels of autophagy-related proteins such as Beclin-1, LC3, and Atg5, thus positively affecting the progression of RA. Network pharmacology analysis revealed that ethyl linoleate (EL), a key component of JJC, targeted DKK1. RA model rats showed a dose-dependent response to EL. It significantly reduced cell proliferation and inflammatory cell infiltration in knee joint synovium and improved tissue structure. EL lowered DKK1 and RANKL levels in knee joint synovium and bone tissue, and increased OPG and LC3 expression. Additionally, it enhanced ALP activity and survival of osteoblasts, promoted cell proliferation and autophagy, protected osteoblast function, and inhibited the differentiation of PBMCs into osteoclasts, demonstrating its potential therapeutic effects on RA pathology. EL, a key component of JJC, exhibits significant therapeutic potential and positive effects in the treatment of RA by influencing the DKK1/Wnt-OPG signaling axis and autophagic processes.

Electroacoustic Comparison and Optimization of Low-Power Impulse Sound-Source Needle Series Electrodes The high-power drive of an impulse sound source with drilling makes the system’s life short and difficult to integrate. This report firstly establishes the pulse discharge experimental system and finite element model, and compares and verifies the typical parameters. Second, the study examines how the energy storage capacitor’s charging voltage, discharge electrode gap, and liquid environment conductivity influence the electroacoustic performance of needle series electrodes. Subsequently, the optimal electrode configuration is identified under power constraints, yielding electroacoustic parameters and curves suitable for low-power impulsive sound sources. The findings reveal that the needle–plate electrode outperforms others in pre-breakdown duration, peak impulse wave strength, highest sound pressure level, and electroacoustic conversion efficiency. However, its higher power demand can be mitigated by lowering the charging voltage and narrowing the electrode gap. The charging voltage of the power-limited needle–plate electrode is only 3.5 kV, the impulse wave intensity reaches 1.27 MPa, and the peak system power is effectively controlled within 6.66 kW. A stable 288 dB SPL output is maintained up to 1 kHz, and above 250 dB in the wide bandwidth of 1–100 kHz. Needle–plate electrodes provide broadband excitation and high intensity SPL output despite power limitations.
