Abstract In recent years, tuned liquid dampers (TLDs) have emerged as a focal point of research due to their remarkable potential for structural vibration mitigation. Yet, progress in this field remains constrained by an incomplete understanding of the fundamental mechanisms governing sloshing-induced loads in liquid-filled containers. Aqueducts present a distinctive case, as the capacity of their contained water to function effectively as a TLD remains uncertain. To address this gap, the present study investigates the generation mechanisms of sloshing loads under non-resonant cases through a two-dimensional (2D) computational fluid dynamics (CFD) model developed in ANSYS Fluent.… More >

Abstract Quality of Service (QoS) assurance in programmable IoT and 5G networks is increasingly threatened by cyberattacks such as Distributed Denial of Service (DDoS), spoofing, and botnet intrusions. This paper presents AutoSHARC, a feedback-driven, explainable intrusion detection framework that integrates Boruta and LightGBM–SHAP feature selection with a lightweight CNN–Attention–GRU classifier. AutoSHARC employs a two-stage feature selection pipeline to identify the most informative features from high-dimensional IoT traffic and reduces 46 features to 30 highly informative ones, followed by post-hoc SHAP-guided retraining to refine feature importance, forming a feedback loop where only the most impactful attributes are More >

Abstract The remediation of acid mine drainage (AMD), characterized by its high concentrations of toxic metal ions and low pH, presents a significant environmental challenge. In this study, exfoliated two-dimensional MoS_₂ nanosheets were prepared using a liquid-phase ultrasonication method and evaluated for their efficiency in removing Cd^²⁺, Cu^²⁺, and Pb^²⁺ from aqueous solutions. Detailed structural and morphological analyses confirmed that the exfoliation process significantly enhanced surface area, pore volume, and exposure of reactive sulfur sites. Through isotherm and kinetic modeling analyses, the adsorption behavior was found to align with the Langmuir model and pseudo-second-order kinetic equation, which implies More >

Abstract Heavy metal pollution has become a pervasive environmental issue affecting numerous regions worldwide. Recently, there has been significant attention given to the application of nano-enabled technologies with the purpose of enhancing plant development and alleviating heavy metal stress. This study aimed to illustrate the potential of zinc oxide nanoparticles (ZnO-NPs) to enhance the morphological traits of D. huoshenense exposed to cadmium (Cd) stress. The chemical structure and elemental composition of the ZnO-NPs were characterised by a series of analytical methods, including X-ray diffraction, UV-Vis spectrometry, XPS, and TEM. Plant samples used were collected at 0, 5,… More > Graphic Abstract

Abstract In recent years, tuned liquid dampers (TLDs) have attracted significant research interest; however, overall progress has been limited due to insufficient understanding of the mechanisms governing sloshing-induced loads. In particular, it remains unclear whether the water in aqueducts—common water-diversion structures in many countries—can serve as an effective TLD. This study investigates the generation mechanisms of sloshing loads during the first-order transverse resonance of water in a U-shaped aqueduct using a two-dimensional (2D) numerical model. The results reveal that, at the equilibrium position, the free surface difference between the left and right walls, the horizontal force… More >

Abstract The growing demand for ocean space has generated significant interest in multi-body floating systems, where gap resonance in confined regions plays a critical role in ensuring the safety of offshore operations. This study develops a numerical tank model using the Smoothed Particle Hydrodynamics (SPH) method, implemented through the open-source code DualSPHysics, to investigate hydrodynamic resonance in a twin-floater system and to examine the influence of internal tank sloshing on its hydrodynamic characteristics. The hydrodynamic behavior of the gap flow between a fixed twin-floater system in the numerical tank is validated through systematic comparison with experimental… More >

Abstract In the context of global change, understanding changes in water resources requires close monitoring of groundwater levels. A mismatch between water supply and demand could lead to severe consequences such as land subsidence. To ensure a sustainable water supply and to minimize the environmental effects of land subsidence, groundwater must be effectively monitored and managed. Despite significant global progress in groundwater management, the swift advancements in technology and artificial intelligence (AI) have spurred extensive studies aimed at enhancing the accuracy of groundwater predictions. This study proposes an AI-based method that combines deep learning with a… More >

Abstract It is evident that complex optimization problems are becoming increasingly prominent, metaheuristic algorithms have demonstrated unique advantages in solving high-dimensional, nonlinear problems. However, the traditional Sparrow Search Algorithm (SSA) suffers from limited global search capability, insufficient population diversity, and slow convergence, which often leads to premature stagnation in local optima. Despite the proposal of various enhanced versions, the effective balancing of exploration and exploitation remains an unsolved challenge. To address the previously mentioned problems, this study proposes a multi-strategy collaborative improved SSA, which systematically integrates four complementary strategies: (1) the Northern Goshawk Optimization (NGO) mechanism… More >

Abstract To unveiled the function of exchanging Sm₂O₃ for B₂O₃ on the physical and mechanostructural traits of multi-component glass, five distinct type (A, B, C, D and E) of glasses originated from (50-x)B₂O₃-10P₂O₅-30TeO₂-10ZnO-xSm₂O₃ (0.1≤x≤1.5, mol%) compositions were fabricated by using ordinary approach of melt-quenching. The noncrystallinity status of the synthesized samples was established by X-ray diffraction (XRD) profile. However, with sequential replacement of B₂O₃ by Sm₂O₃, the deduced values of physical entities such as density (d₃), Sm3+ ions concentration (N_i), field strength (F) and glass hardness (H_v) of our produced glasses were significantly amplified, while the molar volume (V_m) alongside polaron More >

Abstract Using liquid hydrogen as fuel is helpful to the aviation industry to achieve the goal of carbon peak and carbon neutrality. However, the liquid hydrogen storage tank will inevitably slosh during the use inhydrogen-powered aircraft, thus it is necessary to study the thermodynamic characteristics of liquid hydrogen storage tank during the sloshing process. In this paper, the thermodynamic behavior of liquid hydrogen storage tank under external excitation is studied by using Volume of Fluid(VOF) model and Lee model through numerical simulation methods. The changes of pressure and temperature in the process of tank sloshing under… More >
