Abstract Accurate plant species classification is essential for many applications, such as biodiversity conservation, ecological research, and sustainable agricultural practices. Traditional morphological classification methods are inherently slow, labour-intensive, and prone to inaccuracies, especially when distinguishing between species exhibiting visual similarities or high intra-species variability. To address these limitations and to overcome the constraints of image-only approaches, we introduce a novel Artificial Intelligence-driven framework. This approach integrates robust Vision Transformer (ViT) models for advanced visual analysis with a multi-modal data fusion strategy, incorporating contextual metadata such as precise environmental conditions, geographic location, and phenological traits. This combination… More >

Abstract Under the background of the current energy crisis and environmental pollution, the development of green and sustainable materials has become particularly urgent. As one of the most abundant natural polymers on earth, cellulose has attracted wide attention due to its green recycling, sustainable development, degradability, and low cost. Therefore, cellulose and its derivatives were used as the starting point for comprehensive analysis. First, the basic structural properties of cellulose were discussed, and then the extraction and utilization methods of cellulose were reviewed, including Sodium Hydroxide based solvent system, N, N-Dimethylacetamide/Lithium Chloride System, N-Methylmorpholine-N-Oxide (NMMO) system, More > Graphic Abstract

Abstract In this work, we re-investigate a classical mathematical model of untreated HIV infection suggested by Kirschner and introduce a novel non-standard finite-difference method for its numerical solution. As our first contribution, we establish non-negativity, boundedness of some solution components, existence globally in time, and uniqueness on a time interval for an arbitrary for the time-continuous problem which extends known results of Kirschner’s model in the literature. As our second analytical result, we establish different equilibrium states and examine their stability properties in the time-continuous setting or discuss some numerical tools to evaluate this question.

Abstract A new extended distribution called the Odd Exponential Generalized Exponential-Exponential distribution is proposed based on generalization of the odd generalized exponential family (OEGE-E). The statistical properties of the proposed distribution are derived. The study evaluates the accuracy of six estimation methods under complete samples. Estimation techniques include maximum likelihood, ordinary least squares, weighted least squares, maximum product of spacing, Cramer von Mises, and Anderson-Darling methods. Two methods of estimation for the involved parameters are considered based on progressively type II censored data (PTIIC). These methods are maximum likelihood and maximum product of spacing. The proposed More >

Abstract Peanut (Arachis hypogaea) is of international importance as a source of oil and protein. Soil salinity is one of the most significant abiotic stress factors affecting the yield and quality of peanuts. This study evaluated the potential of a seaweed-based biostimulant to enhance emergence and seedling growth of four peanut cultivars (‘Ayse Hanım’, ‘Halis Bey’, ‘NC-7’, and ‘Albenek’) under increasing salinity levels. The experiment was conducted under greenhouse conditions using a randomized complete block design with four replicates. Seeds were sown in trays and treated with two doses of seaweed extract (0 and 5 g L⁻¹) applied… More >

Abstract Objectives: Ovarian cancer, a leading cause of gynecological malignancy-related mortality, is characterized by limited therapeutic options and a poor prognosis. Although pyrimethamine has emerged as a promising candidate demonstrating efficacy in treating various tumors, the precise mechanisms of its antitumor effects remain obscure. This study was specifically designed to investigate the mode of action underlying the antitumor effects of pyrimethamine in preclinical settings. Methods: The effects of pyrimethamine on cellular proliferation were meticulously assessed using both the cell counting kit 8 (CCK-8) assay and the colony formation assay, with the effects further confirmed in a… More >

Abstract Ti-Hf-Zr-Nb-Ta refractory high-entropy alloys (RHEAs) exhibiting a dual-phase structure resulting from martensitic transformation offer significant ductility enhancement, but their design requires precise control of the phase stability between body-centred cubic (BCC) and hexagonal close-packed (HCP) phases. This study establishes a comprehensive thermodynamic database for the Ti-Hf-Zr-Nb-Ta system using the 3rd-generation Calculation of Phase Diagrams (CALPHAD) model. The reliability of the database is validated by the strong agreement between the calculated thermodynamic properties and phase equilibria and the experimental data for pure element, as well as for binary and ternary systems. Utilizing this database, the phase… More >

Abstract Hydraulic-electric systems are widely utilized in various applications. However, over time, these systems may encounter random faults such as loose cables, ambient environmental noise, or sensor aging, leading to inaccurate sensor readings. These faults may result in system instability or compromise safety. In this paper, we propose a fault compensation control system to mitigate the effects of sensor faults and ensure system safety. Specifically, we utilize the pressure sensor within the system to implement the control process and evaluate performance based on the piston position. First, we develop a mathematical model to identify optimal parameters… More >

Abstract With the rapid integration of renewable energy sources, modern power systems are increasingly challenged by heightened volatility and uncertainty. Doubly-fed variable-speed pumped storage units (DFVS-PSUs) have emerged as promising technologies for mitigating grid oscillations and enhancing system flexibility. However, the excitation converters in DFVS-PSUs are prone to significant issues such as elevated common-mode voltage (CMV) and neutral-point voltage (NPV) fluctuations, which can lead to electromagnetic interference and degrade transient performance. To address these challenges, an optimized virtual space vector pulse width modulation (OVSVPWM) strategy is proposed, aiming to suppress CMV and NPV simultaneously through coordinated… More >
