Abstract: Background/Objectives: Prolonged smartphone use is associated with musculoskeletal and neurological hand symptoms; however, specialized tools for bilateral assessment remain limited. This study aimed to develop and evaluate the psychometric properties of the Smartphone-Related Hand Symptoms (S-HAND) scale. Methods: A total of 456 participants (mean age: 21.8 ± 6.65 years) were included. The sample was randomly divided into two independent subsamples for Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). Internal consistency was assessed using Cronbach’s alpha and McDonald’s omega coefficients. Test–retest reliability was evaluated in 75 participants using Intraclass Correlation Coefficients (ICC). Measurement precision was determined using the standard error of measurement (SEM) and minimal detectable change (MDC95). Concurrent validity was examined using correlations with general hand pain intensity scores. Results: EFA and CFA supported a three-factor structure consisting of Pain Symptoms, Numbness Symptoms, and Functional Impact. The final CFA model demonstrated excellent fit (CFI = 0.991, TLI = 0.986, RMSEA = 0.049, SRMR = 0.033). Standardized factor loadings ranged from 0.685 to 0.932. Internal consistency was high (Cronbach’s α = 0.857–0.940; McDonald’s ω = 0.863–0.942), and test–retest reliability was excellent (ICC = 0.800–0.907). SEM and MDC95 for the total score were 4.67 and 12.95, respectively. Significant positive correlations with pain intensity scores supported concurrent validity (r = 0.61–0.73, p < 0.001). Conclusions: The S-HAND scale is a reliable and valid instrument for assessing smartphone-related hand symptoms in clinical and research settings.

Abstract: Inflammatory rheumatic diseases exhibit dynamic and heterogeneous inflammatory activity, yet clinical monitoring remains episodic and temporally sparse, limiting early intervention and delaying treatment adjustment. Advances in biosensing technologies, wearable monitoring, and computational modeling offer opportunities to transition toward continuous, data-driven disease assessment. In this review, we synthesize evidence across rheumatology, immunology, biosensing, and digital health to examine how multimodal measurement approaches can support clinically actionable decision-making. We introduce a structured framework—the “Measurement Stack”—that links three components: biological signal domains (systemic, synovial, imaging-derived, and physiological), sensing platforms with distinct temporal and specificity trade-offs, and computational inference layers including feature extraction, multimodal data integration, and predictive modeling. We emphasize that the clinical value of biomarkers depends not on association alone but on actionability, defined by temporal sensitivity, repeatability, robustness to heterogeneity and signal noise, and alignment with clinical decisions. Key methodological considerations include feature engineering for sparse and continuous data, handling missingness and signal drift, calibration-aware validation, temporal and external validation, and decision-curve analysis for clinical utility. A decision-centric mapping aligns measurement and modeling strategies with clinical tasks such as early flare detection, differentiation of flare from infection, therapy switching or tapering, and monitoring of treatment response. By integrating biosensing advances with clinically grounded evaluation standards, this review outlines pathways toward interpretable, deployment-ready monitoring systems enabling proactive and personalized management of inflammatory rheumatic disease.

Abstract: Aerodynamic drag is one of the two principal external sources of energy loss in on-road vehicles – the other being rolling resistance – and it critically affects the range of battery-electric and fuel cell-electric vehicles. To ensure accurate early-stage analysis such as vehicle range prediction and sizing of energy storage and powertrain components, it is essential to incorporate realistic representations of air resistance. Despite its importance, due to limited data availability air resistance is often simplified using zero crosswind and "nominal air conditions", which tend to underestimate the actual energy required to overcome aerodynamic drag. This approach also fails to capture the variability introduced by changing environmental conditions, leading to significant discrepancies in energy consumption and, consequently, vehicle range. As a result, evaluating system robustness and conducting meaningful trade-off analyses between different vehicles or vehicles configurations becomes challenging. This study demonstrates how publicly available meteorological data can be utilized to quantify long-term variations in aerodynamic drag. By analyzing multiple years of weather observations, we derive realistic distributions of aerodynamic energy losses – capturing not only mean values but also the full range of variability. These distributions enable probabilistic modeling of vehicle performance, thereby supporting robust system design and informed trade-off decisions across various levels of vehicle architecture. To demonstrate this, we compare two different tractor/semitrailer configurations.

Abstract: Public trust is essential for the effectiveness and long-term sustainability of open government data (OGD) initiatives, particularly in small island developing states (SIDS), where digital governance systems often operate under infrastructural and institutional constraints. Despite growing global research on OGD trust, limited research has examined how the quality dimensions of information systems' success models shape citizens’ trust in OGD platforms within Caribbean SIDS. This study investigates the effects of service quality, system quality, information quality, and data quality on public trust in OGD using an extended information systems success model (ISSM). Data were collected through an online survey of 904 respondents across Caribbean SIDS and analysed using partial least squares structural equation modelling (PLS-SEM). The findings indicate that all proposed relationships were statistically significant. Data quality emerged as the strongest predictor of public trust, followed by system quality. Service quality also significantly influenced system quality, information quality, and data quality. In addition, system quality, information quality, and data quality mediated the relationship between service quality and public trust in OGD. This study extends the ISSM framework by conceptualising data quality as a distinct construct within OGD environments. The findings provide practical insights for governments seeking to strengthen transparency, citizen engagement, and sustainable digital governance through higher-quality OGD systems and datasets. The results further highlight the role of open government platforms in improving public service delivery by providing citizens with complete, accurate, and accessible data, interactive feedback mechanisms, and effective data visualisation tools that support informed decision-making and public participation.

Abstract: The rapid advancement of generative large language models (LLMs) has sparked significant interest in their poten- tial to transform higher education, particularly in fostering student engagement. While these models offer novelopportunities for personalized learning and interactive experiences, their integration into academic settings remains underexplored, with varying implications for pedagogy, ethics, and institutional policy. This systematic literaturereview examines the role of generative LLMs in enhancing student engagement across multiple dimensions, includ- ing their impact on learning outcomes, academic writing, subject-specific applications, and ethical considerations.We synthesize existing research to identify key trends, challenges, and gaps in the current understanding of how these technologies are reshaping educational practices. A rigorous methodological approach was employed to select and analyze relevant studies, ensuring a comprehensive evaluation of the field. The findings reveal that generative LLMs can significantly influence student engagement by facilitating adaptive learning environments and supporting creative problem-solving; however, concerns about academic integrity, equitable access, and pedagogical alignment persist. The review also highlights emerging tools and systems designed to integrate LLMs into education, alongside institutional and student perspectives on adoption. Based on the synthesized evidence, we discuss future directions for research and policy, emphasizing the need for balanced frameworks that harness the benefits of generative AI while addressing its risks A. Chowdhury et al., 2025. This study contributes a structured overview of the current landscape, offering insights for educators, researchers, and policymakers navigating the evolving intersection of AI and higher education.

Abstract: Context: Accurate citrus crop mapping is essential for agricultural monitoring, production planning, and supply-chain management, particularly in Brazil, one of the world’s leading orange producers and the leading orange-juice exporter. Satellite image time series from Sentinel-2 provide rich spectral and temporal information for crop identification. However, citrus mapping remains challenging due to fragmented agricultural landscapes, cloud contamination, class imbalance, and spectral overlap with other vegetation classes. Problem: Conventional machine learning models often depend on handcrafted vegetation indices, while attention-based deep learning models may require larger datasets and can become unstable under geographically constrained conditions. Therefore, there is a need for a compact and robust deep learning architecture capable of extracting citrus phenological signatures directly from multispectral time-series data. Methods: This study evaluates a Spatio-Temporal Pixel-Set Encoder Convolutional Neural Network (PSE-CNN) for citrus crop classification in the immediate geographic regions of São João da Boa Vista and Mogi Guaçu, São Paulo, Brazil. MapBiomas Collection 10.1 data from 2019 to 2024 were used to derive reference polygons, and Sentinel-2 imagery was processed into cloud-masked, 15-day temporal composites using ten spectral bands. The proposed PSE-CNN was benchmarked against PSE-TAE, PSE-Transformer, Random Forest, and XGBoost using spatially grouped data partitioning and temporal test years. Results: The proposed PSE-CNN achieved the highest Unified F1-Score of 0.703 and the lowest coefficient of variation of 2.28%, indicating stronger inter-annual stability across test years and random seeds among the evaluated models. It also outperformed classical models that relied on handcrafted vegetation indices and demonstrated greater overall stability than attention-based deep learning alternatives. Conclusions: The results indicate that combining pixel-set encoding with temporal convolution provides a resource-aware and stable framework for retrospective citrus crop mapping from Sentinel-2 satellite image time series. These findings suggest that PSE-CNN can support scalable agricultural monitoring, contributing to sustainable crop inventory systems in regions where labeled data and computational infrastructure are limited.

Abstract: The sustainability-focused issues of the built environment require a change in architectural education not to form-based design methods but to adaptive, systems-based, and performance-oriented thinking. The paper explores a unified pedagogical model that incorporates biomimicry, parametric thinking, and modular design in improving sustainable design learning in architectural studios. The study adopts a qualitative case study method to investigate Architectural Design Studio 4 at the American University of Ras Al Khaimah (AURAK), where third-year architecture students undertake a discovery-based design process that takes three sequential stages. The students explored biological systems to first identify transferable principles, then implemented the principles in parametric modules with computational software like Dynamo and Revit and then reused these systems to create high-rise architecture. The results suggest that biomimicry combined with parametric workflows helps to achieve optimization but not maximization, which allows students to come up with flexible, efficient, and reusable design systems. The modular design approaches were essential in dealing with the architectural complexity, especially in the high-rise application and parametric tools enabled exploration of many variations and informed decisions based on the performance. The undisclosed final design goal promoted critical thinking, conceptualization, and problem-solving. The research provides the literature of architectural education with empirical evidence as it illustrates how an integrated process-based approach can improve the knowledge of sustainability, system logic, and adaptability in students. The study finds that integrating biomimicry and parametric design in modular and discovery-oriented studios is a sound pedagogical approach to equip future architects to deal with modern environmental and technological demands.

Abstract: Background: Reliable intraoperative tools for donor liver assessment are needed, particularly in the context of steatotic and extended-criteria grafts. While histology remains the reference standard, it is limited by sampling variability and logistical constraints. Preservation fluid may provide a complementary, whole-organ source of biochemical information. Methods: In this single-center prospective exploratory pilot study, liver tissue and preservation fluid were collected from 30 donation-after-brain-death grafts during the back-table procedure. Biochemical parameters, including arginase activity, β-hydroxybutyrate (βHB), acetoacetate, and total protein, were measured using standard assays. Associations with histological steatosis on wedge biopsy were assessed using nonparametric correlation analyses, and paired preservation-fluid samples were compared. Results: Most grafts demonstrated absent or mild steatosis; only two exhibited moderate steatosis, and none were severely steatotic. No preservation-fluid biomarker showed a statistically significant association with histological steatosis. Weak, non-significant positive correlations were observed for βHB and arginase activity (Spearman r ≈ 0.33–0.35). Protein concentration and arginase activity decreased between start and end samples, whereas ketone body levels remained relatively stable. Conclusions: Preservation-fluid biomarker measurement during routine graft preparation is feasible. Although no significant associations with histological steatosis were identified, the observed weak correlations suggest possible associations requiring validation in larger studies. Larger, adequately powered studies including a broader spectrum of steatosis and clinically relevant outcomes are required to determine potential clinical applicability.

Abstract: Background: Pregnancy-related transient osteoporosis of the hip (PR-TOH) is a rare and often underdiagnosed condition presenting with acute hip pain in late pregnancy or postpartum. Due to its nonspecific clinical presentation, it is frequently misinterpreted as common musculoskeletal or pelvic girdle pain, leading to delayed diagnosis and suboptimal management. Case Presentation: We report a rare case of bilateral PR-TOH in a 35-year-old primigravida diagnosed at 31+6 weeks of gestation. The patient presented with progressively worsening hip pain leading to severe mobility impairment. Initial investigations, including ultrasound and laboratory testing, were inconclusive. Definitive diagnosis was established by magnetic resonance imaging (MRI), demonstrating characteristic bone marrow oedema in both femoral heads. The patient was managed conservatively with analgesia, restricted weight bearing, and multidisciplinary care involving obstetrics, endocrinology, and orthopaedics. Pregnancy was successfully prolonged until 37+4 weeks, when caesarean section was performed due to clinical deterioration. Postpartum management included calcium and vitamin D supplementation and rehabilitation. Follow-up demonstrated significant improvement in bone mineral density on DEXA and complete clinical recovery at 12 months. Conclusions: PR-TOH should be considered in pregnant or postpartum women presenting with persistent hip pain and progressive functional limitation. Early use of MRI is essential for accurate diagnosis and differentiation from more common pregnancy-related conditions. Prompt recognition and multidisciplinary management are crucial to prevent complications and optimize maternal and obstetric outcomes.

Abstract: This study characterized standard biochars produced at 300, 400, and 500 °C alongside a locally made biochar (LBC, drum kiln method with newly devised method of Bababe) to assess fertilizer value and toxicity against IBI thresholds. Pyrolysis temperature strongly influenced properties: electrical conductivity and salt content increased with tempera-ture (BC300 and BC500 highest; LBC lowest). All standard biochars were highly alkaline (pH 10.26–10.57), while LBC was near-neutral (7.84). Maximum carbon content occurred at 300–400 °C (56.8–56.9 %). At 10 kg ha⁻¹, standard biochars supplied 308–331 kg ha⁻¹ K, with BC400 providing the highest Ca and Mg. LBC had the highest volatile micronu-trients (B, Cu, Fe, Mn), which decreased with rising temperature. It can be particularly well suited to fertilizer coating or blending systems, especially for salt-sensitive soils where application rates are kept low (< 10 t ha⁻¹), thereby limiting agronomic risks such as Mo contaminant loading. Nevertheless, molybdenum levels in all biochars were 5–8 times above IBI safe limits (5–75 mg kg⁻¹), posing toxicity risk at 10 t ha⁻¹ application. Cd was undetectable, reduced Pb by 90 % at 400–500 °C, and kept Ni and Pd within limits. SEM revealed BC400 had optimal honeycomb porosity and homogeneous mineral dis-tribution. BC400 is most suitable for agricultural fertilizer value, BC500 for carbon se-questration, BC300 for potassium supply, and LBC as a low-cost, low-salinity material. However, excessive molybdenum across all biochars relates feedstock composition as the paramount safety factor. The weakness and limitation of this studies lies in the resource constraints from use of one feedstock, absence of direct measurement of surface area and phosphorus, and absence of measurement of biochar stability.

Abstract: The number of human genetic variants cataloged in dbSNP has plateaued since 2021, with over ~1.1 billion variants housed. Since the human pangenome reference has enabled the precise identification of even structurally complex variants, capturing the entire spectrum of human genetic variants is almost achievable. However, the clinical impacts of most genetic variants still remain elusive. This is due to limitations in genome-wide association study (GWAS), the standard framework for variant interpretation, which relies solely on statistical assumptions. GWAS cannot interpret low‐frequency alleles and capture molecular interactions between variants, hindering its ability to explain complex traits and diseases. Recently, large language models (LLMs) enabled accurate inference of human genetic variants’ pathogenicity even without requiring a large sample size or prior annotations by modeling the biological principles encoded within the genome. For instance, Evolutionary Scale Modeling (ESM1b) successfully predicted missense variants in ClinVar, achieving an auROC of up to 0.905. In addition, Evo 2 classified non-coding pathogenic variants in ClinVar with an auROC of 0.987 for single nucleotide variants (SNVs) and 0.971 for non-SNVs. These results suggest that although yet limited to pathogenicity prediction, integrating multiomic and clinical data through LLM will enable the complete clinical interpretation of human genetic variants.

Abstract: Ammonia-oxidizing bacteria (AOB) are vital for the nitrogen cycle and wastewater treatment, yet their recalcitrance to isolation and cultivation hampers industrial application. To isolate an efficient strain and optimize its culture conditions for high-ammonia wastewater treatment, we collected water samples from a polluted river in Zhongshan City. After enrichment, a strain was isolated via gradient dilution and silica gel plating, identified by scanning electron microscopy and 16S rDNA sequencing as Nitrosomonas europaea W4 (99.93% similarity to the type strain). Single-factor medium optimization examined CaCO₃ and Fe²⁺/Fe³⁺, while temperature and initial ammonia nitrogen effects were tested, and landfill leachate was used for verification. CaCO₃ shortened the lag phase without affecting maximum specific growth rate; replacing Fe³⁺ with Fe²⁺ further reduced lag and enhanced the ammonia oxidation rate. Optimal growth occurred at 25–30 °C and an initial ammonia nitrogen concentration of ~2000 mg/L. In landfill leachate, the strain increased the ammonia degradation rate 6.3-fold. Overall, N. europaea W4 exhibits high ammonia oxidation efficiency, and the optimized medium and conditions improve its proliferation and metabolic stability, providing a basis for cultivation and application in treating high-strength ammonia nitrogen wastewater.

Abstract: Large language models (LLMs) increasingly require robust evaluation under realistic instruction-following conditions, particularly for fine-tuned task-specific adapters operating in multilingual environments. This study proposes a scenario-adaptive evaluation framework for assessing the reliability of fine-tuned text models across two application regimes: misinformation detection (disinfo) and knowledge-grounded factual biography generation (heroes). The framework integrates automated generation of balanced risk-oriented scenarios, bilingual evaluation in English and Ukrainian, the LLM-as-a-Judge paradigm, and multidimensional robustness analysis through the Alignment Robustness Index (ARI). Six LoRA-adapted models based on Qwen2.5-3B-Instruct, SmolLM2-1.7B-Instruct, and TinyLlama-1.1B-Chat-v1.0 were evaluated. The implemented pipeline generated 2052 scenarios and 6156 model responses, producing a final bilingual analytical subset of 4104 judged records. Experimental results show that task-specific adaptation produces task-dependent robustness profiles. In the disinfo case, Qwen2.5-3B achieved the strongest overall performance, combining the highest safety and classification accuracy. In contrast, the heroes case revealed a more compressed and multidimensional vulnerability space without a single dominant model. The results further demonstrate the importance of multilingual evaluation, as weaker adapters exhibited substantially larger cross-lingual safety gaps. Overall, the proposed framework provides a reproducible and practically applicable methodology for auditing fine-tuned language models under imperfect instructions.

Abstract: International communication scholarship has undergone a paradigmatic reorientation since 2000, yet the field's conceptual repertoire has expanded more rapidly than it has been theoretically integrated. This systematic literature review interrogates that fragmentation by mapping the trajectory of the field across the period 2000–2026 and assessing the extent to which its proliferating frameworks—cultural imperialism, hybridization, network society, platform imperialism, data colonialism, computational propaganda, sharp power, and algorithmic governance—constitute cumulative theoretical advancement or analytically incommensurable parallel vocabularies. Following PRISMA 2020 procedures (Page et al., 2021) and a thematic synthesis design (Thomas & Harden, 2008), the review consolidates peer-reviewed scholarship across seven major communication databases into seven thematic clusters: cultural globalization and media flows; comparative journalism and cross-national media systems; de-Westernization and decolonial currents; phantomization, digital sovereignty, and media infrastructures; disinformation, computational propaganda, and information disorder; soft power, public diplomacy, and affective strategic communication; and the integration of generative artificial intelligence into transnational communication. Three theoretical findings emerge. First, the apparent succession of paradigms from broadcast-era to platform-era frameworks is better understood as conceptual layering, in which power-asymmetric models persist in modified form rather than being displaced by network-based alternatives. Second, the field's longstanding tension between structural and agentic accounts has been reconfigured—but not resolved—by the platform turn, with infrastructural analysis emerging as a potential synthesizing register (Parks & Starosielski, 2015; Plantin & Punathambekar, 2019). Third, the persistent disjuncture between the field's de-Westernization commitments and its bibliometric realities (Demeter, 2020) is theoretically consequential, indicating that epistemic asymmetries function not as residual artifacts but as constitutive features of contemporary international communication knowledge production. A seventh identified gap—the under-theorization of affective dimensions of international communication—extends the review's analytic horizon to include emergent comparative work on emotion, civilizational rhetoric, and cross-border public engagement (Çelik, 2025; Hameleers & Garnier Ortiz, 2024; Wahl-Jorgensen, 2019). The review proposes a future research agenda centered on epistemic pluralism, methodological diversification, infrastructural and material analysis, and sustained engagement with planetary-scale technological change.

Abstract: This research examines how climate change intensifies urban heat stress, particularly in public spaces where mechanical cooling is impractical. A climate-driven, systems-level numerical model is developed to evaluate the pre-installation feasibility of portable, solar-powered misting canopies. Hourly Typical Meteorological Year data (TMYx, 2009–2023) are analyzed for each city to estimate photovoltaic (PV) energy yield, electrical load, potential misting duration, water demand, and PV-to-load autonomy under summer daytime conditions. Misting operation is governed by an adaptive, rule-based control strategy based on air temperature, relative humidity, and solar radiation. To enable systematic comparison, K-means clustering is applied to classify the cities into six archetypal summer climate zones. Results indicate that evaporative cooling feasibility is driven more by ambient humidity than by air temperature. Hot-dry interior cities achieve the longest average misting duration (502.65 hours) and highest water consumption (30,486 L per module), but exhibit the lowest PV-to-load autonomy ratio (1.53) due to high energy demand for pumping. In contrast, humid Black Sea cities show minimal misting duration (13.11 hours) and water use (478 L) yet achieve the highest autonomy (40.91) because of limited system operation. It is important to note that the autonomy ratio reflects a seasonal energy balance rather than continuous off-grid capability. Overall, the adaptive control approach effectively aligns water and energy use with climatic suitability across all clusters. The proposed framework offers a scalable and quantitative screening tool to inform the design and deployment of PV-powered outdoor cooling systems across diverse urban environments.

Abstract: The ambitious roadmap for a sustainable transport system adopted by the European Commission (EC) by 2050 includes the deployment of an extensive Electric Vehicle Charging Stations (EVCSs) infrastructure, which introduces significant challenges for distribution power grids. High power demand, particularly from fast-charging systems, may lead to network overloading and voltage unbalance. In addition, recent measurement campaigns highlight substantial changes in grid impedance and the emergence of resonance phenomena, together with the injection and propagation of high-frequency conducted disturbances. These effects extend over a wide frequency range, up to several hundreds of kHz, causing degradation, aging and malfunction of network assets, in particular Power Line Communications. This paper provides a comprehensive and updated review of the impact of EVCSs on electrical grids, covering power flow, power quality, stability, and impedance-related interactions. Particular attention is given to the role of power-electronic converters, high-frequency emissions, and the associated challenges in measurement and standardization. The analysis highlights that EVCS integration fundamentally alters the nature of electrical loads, requiring new approaches for grid planning, monitoring, and regulation. The study identifies key research gaps and outlines future directions to ensure the reliable and sustainable integration of electromobility into modern power systems.

Abstract: We propose a generalized definition of rest energy in which mc^2 is interpreted not as an immutable intrinsic quantity, but as a latent kinetic form. Within this framework, any kinetic contribution—Fermi, Coulomb, or relativistic gravitational—that assumes a rest-like structure becomes energetically dormant unless a non-arbitrary infinitesimal deficit is introduced. We show that such a deficit leads naturally to an alternative relativistic solution characterized by extreme excitation and particle-number amplification, while preserving total energy conservation. This mechanism gives rise to a bound, atom-like gravitational configuration at macroscopic scales, referred to here as a giant atom, governed by a precise orbital condition linking de Broglie coherence to gravitational binding. A scalar field condensate is introduced not as a new source of energy, but as a geometrical and dynamical mediator: it traps the configuration, screens the enormous Coulomb self-energy, and enables migration through its gradient structure and intrinsic frequency. Importantly, the model does not rely on a phase transition or energy injection. Instead, the dynamics become effective only when cosmological damping falls below the intrinsic frequencies of the trapped system. We argue that the initial closed configuration can be established at very early times (∼〖10〗^(-5) s before BB) and remain dynamically frozen, protected by the scalar field, until plasma dilution around T∼0.1MeV allows the latent kinetic structure to express a minute energetic imbalance. This marks the onset of gravitational potential deposition and the emergence of large-scale ordered motion. The framework offers a pathway toward the formation of atom-like gravitational systems, with potential implications for early-universe dynamics and the origin of planetary system.

Abstract: A serious problem facing power systems today is the deterioration of power quality (PQ), driven mainly by the widespread use of non-linear loads, such as power electronic converters and adjustable-speed drives. These loads inject harmonic currents into the network, resulting in voltage distortion, increased losses, overheating, and reduced system efficiency. Therefore, harmonic mitigation and reactive power compensation are necessary to ensure stable and reliable operation. This paper presents the development of a Shunt Active Power Filter (SAPF) to become an intelligent Shunt Active Power Filter Conditioner (SAPFC) that operates under different loading conditions (linear, non-linear, or mixed). As a result, a conventional PI controller is upgraded with a Fuzzy Gain Scheduling (FGS) technique optimized by the Whale Optimization Algorithm (WOA) in order to keep the DC-link capacitor voltage stable. In addition, an adaptive instantaneous dq theory is used to produce accurate reference currents. The proposed intelligent SAPFC is implemented and validated in MATLAB-Simulink, where simulation results show maximizing the SAPFC's effectiveness in minimizing harmonic distortion to less than 0.7% and achieving a near-unity power factor under different operating conditions. The integrated SAPFC, with its intelligent control, offers a robust and adaptive solution for improving power quality in modern electrical systems, thereby increasing efficiency and reducing power losses.

Abstract: Dietary fibre (DF) and bioactive compounds (BC) are essential components of a healthy diet and are abundant in plant‑rich dietary patterns. Increasing evidence demonstrates that their combined and synergistic actions significantly influence human health, largely through their effects on the gut microbiota. This review highlights the need for more precise terminology regarding DF and BC, as inconsistent use of these terms can create confusion among both consumers and researchers. The DF complex encompasses all non-digestible food components that have a positive effect on human health, together with the BC associated with them, recognising that DF often serves as a carrier for these compounds throughout the digestive tract. Although recommended intakes for BC have not been established, intake levels observed in populations adhering to healthy dietary patterns may serve as useful reference points. Updated data on the intake and estimated bioavailability of polyphenolic compounds in the contemporary Spanish diet are presented.
