Abstract The need for intelligent learning frameworks that can function under stringent limitations relating to privacy, energy, scalability, and trust has increased due to the Internet of Things’ (IoT) and the Internet of Artificial Things’ (IoAT) explosive expansion. Federated Learning (FL), which allows collaborative model training without sharing raw data, has become a potential approach. Non-IID data delivery, inconsistent client engagement, vulnerability to poisoning assaults, and low resource knowledge are among of the significant obstacles that FL alone must overcome. Blockchain integration adds extra overhead in terms of latency, energy consumption, and scalability, but it has… More >

Abstract Phishing has become the most common cybersecurity threat and increasingly exploits human factors rather than technical vulnerabilities. This study examined the relationships between cybersecurity awareness, training frequency, user cyber-hygiene behaviour, organisational culture, risk perception, and self-reported phishing vulnerability and the theoretical basis of this research is the Technology Threat Avoidance Theory (TTAT). A quantitative correlational design was used for data collection and analysis with Pearson correlation in structured questionnaires. The results indicated that the five independent variables have a significant positive relationship with phishing vulnerability. The increased awareness and regular training correlate with greater recognition… More >

Abstract Backgrounds: The mental health consequences of social media use remain debated. Drawing on the “rich-get-richer” perspective, this study examines whether social media access interacts with perceived social resources to shape depression risk among Chinese students. Methods: We analyze nationally representative data from the 2020 and 2022 waves of the China Family Panel Studies (CFPS), constructing a two-period unbalanced student panel. High-dimensional fixed effects linear probability models are estimated with province and year fixed effects and province-specific linear trends. Mediation analyses follow the Baron and Kenny framework and are supplemented by Sobel-Goodman and bootstrap tests. Heterogeneity is… More >

Abstract Background: In adolescence, anxiety symptoms are a common mental health problem. The purpose of this study was to evaluate the possible chain-mediating functions of fundamental psychological needs satisfaction and self-compassion in the link between adolescent anxiety and parental psychological control. Methods: Convenience sampling was used to pick 8342 middle school pupils from the Chinese regions of Sichuan and Hebei for this cross-sectional study. Participants filled out validated measures of anxiety symptoms, self-compassion, fundamental psychological needs satisfaction, and parental psychological control. To test the suggested chain mediation model, data were examined using descriptive statistics, correlation analysis, and… More >

Abstract Background: The pervasive use of short-form video platforms such as TikTok has introduced unprecedented challenges to student attention, cognitive self-regulation, and academic performance. Recent interest has grown around “nudging” strategies, or non-coercive behavioral interventions, to help students regain control over their digital habits in educational settings. This review aims to (1) synthesize recent empirical evidence on the attentional and academic impact of problematic social media use (particularly TikTok) among students, (2) identify and classify nudging strategies that mitigate these effects, and (3) evaluate their relative effectiveness and practical application in educational contexts. Methods: A scoping review… More >

Abstract The modification of melamine–urea–formaldehyde (MUF) adhesives with lignosulfonates (LS) represents a promising strategy for developing more sustainable wood-based panels. However, the influence of the counterion type remains poorly understood. In this study, the effect of lignosulfonate counterions on adhesives performance and properties of MUF-bonded particleboards was investigated, with a focus on sodium (NaLS) and magnesium (MgLS) lignosulfonates incorporated at 2.5%, 5.0%, and 7.5%. Adhesives performance was characterized by measuring dry solids content, dynamic viscosity, gelation time, and pH. The produced particleboards were evaluated in terms of density, bending strength, modulus of elasticity, internal bond strength… More > Graphic Abstract

Abstract The development of seaweed-derived products, particularly carrageenan, is increasingly prioritized in Indonesia to support sustainability and strengthen the local economy. Despite extensive studies on carrageenan extraction, systematic comparisons between locally extracted carrageenan and specific local commercial products remain limited. This study addresses this gap by directly comparing carrageenan extracted from Eucheuma cottonii harvested in Lombok, Indonesia, with a locally produced commercial carrageenan as a quality benchmark. Carrageenan extraction was performed using alkaline KOH treatment followed by ethanol precipitation. The extracted carrageenan exhibited a relatively high viscosity (61.16 cP) and a low sulfate content (11.58%). FTIR analysis More >

Abstract Grape by-product of the wine industry, rich in polyphenols, tannins, lignin, and natural waxes, the chemical constituents grape skins 45%–55%, seeds 25%–35%, and stems or stalks 25%–35% weight of grape provide intrinsic cross-linking, mechanical reinforcement, antioxidant activity, and water resistance, closely replicating the effects of conventional vegetable tanning without using toxic chemicals. This review comprehensively examines current eco-friendly extraction methods to isolate bioactive compounds, as well as fiber modification techniques to improve polymer compatibility. Composite fabrication involves blending processed grape waste fibers with bio-based polymers and renewable plasticizers to produce materials exhibiting competitive tensile strength,… More >

Abstract Plant-based starch has emerged as a promising natural binder in biocomposites owing to its biodegradability, renewability, and functional adaptability. This study critically reviews the extraction, modification, and performance of starches derived from sources such as corn, potato, and cassava, with particular attention to their calorific behaviour as measured through bomb calorimetry. Calorimetric analysis provides insight into the energy density and combustion efficiency of starch binders, parameters that influence both processing and End-of-life valorisation of biocomposites. Through physical, chemical, enzymatic, and genetic modifications, the inherent limitations of native starch such as moisture sensitivity and low mechanical More > Graphic Abstract

Abstract Balancing heat transfer performance with material cost and refrigerant charge remains a key challenge in split air conditioning systems. To address this issue, the present study proposes a finned-tube heat exchanger with a variable-diameter configuration, combining 5.2 mm and 7.3 mm tubes for use with R290 refrigerant. Three hybrid arrangements are examined against a conventional baseline with uniform 7.3 mm tubes, differing in the number and spacing of the 5.2 mm tubes integrated within the heat exchanger layout, thereby enabling targeted structural and thermal optimization of the indoor unit. An integrated methodology, based on a… More >
