Development of an LCA-Based Environmental Scorecard Framework for Sustainable Palm Oil Mill Waste Management

The sustainable management of palm oil mill biomass is essential for reducing greenhouse gas (GHG) emissions and promoting resource recovery. This study evaluated five palm oil mill waste management practices at a single palm oil mill (n = 1). It developed an LCA-based environmen...

Analysis of disturbance dynamo and plasma bubble phenomena over Malaysia during the May 2024 geomagnetic storm

This study presents the first observational report of ionospheric disturbance dynamo (Ddyn) signatures derived from Malaysian magnetometer stations and examines their relationship with equatorial plasma bubble (EPB)-related ionospheric irregularities during the extreme geomagneti...

Structural Performance of Corroded Precast Concrete Connections

Abstract Precast concrete offers significant advantages in modern construction, but its long-term performance is critically governed by the durability of its connections. These connections act as preferential sites for reinforcement corrosion, making them the most vulnerable comp...

Effect of N -Methyl-2-pyrrolidone/Dichloromethane Solvent Ratio towards the Retention of Magnesium Sulfate and Ibuprofen by Polylactic Acid Membranes

Abstract Polylactic acid (PLA) membranes are sustainable alternatives to petroleum-based polymers, yet inherent fragility often necessitates leachable additives for mechanical robustness that may contaminate the permeate. Cost-effective PLA 4032D pellets were used in this work to...

Quantum-Resistant Security Technologies for Resource-Constrained Edge Devices: Challenges and Lightweight Countermeasures

With the rapid advancement of quantum computing technology, IoT edge devices widely deployed in industrial settings are facing severe threats to their quantum-resistant security. This work focuses on the challenges of adapting Quantum Key Distribution (QKD) and Post-Quantum Crypt...

Polyphenol-Enriched Black Soldier Fly Larvae (Hermetia illucens) Meal Improves Lipid Quality and Delays Oxidative Deterioration of Refrigerated Broiler Breast Meat

This study investigated whether black soldier fly larvae meal (BSFL; Hermetia illucens L.) produced on polyphenol-rich agro-industrial by-products could enhance broiler meat lipid quality and oxidative stability during refrigerated storage. A total of 200 one-day-old Arbor Acres...

Development of a home-based pulmonary rehabilitation program for long COVID in Jordan using an expert consensus survey informed by qualitative item generation

Long COVID is associated with persistent fatigue, dyspnea, and reduced functional capacity, yet access to centre-based pulmonary rehabilitation remains limited, particularly in low- and middle-income settings. This study aimed to develop a consensus-based, evidence-informed home-...

Stakeholder perspectives on service factors influencing patient loyalty in Malaysia’s dental tourism sector: a qualitative survey

Abstract Aim To explore stakeholder perspectives on the service-related, organisational, and policy factors perceived to influence patient loyalty in Malaysia’s dental tourism sector. Materials and methods This qualitative study recruited 17 stakeholders directly involved in dent...

Informal teacher leadership and teacher occupational well-being in Chinese higher education: The role of sense of power

This study examined the relationships among informal teacher leadership, sense of power, and teacher occupational well-being among university teachers in eastern coastal China. Survey data from 404 full-time university teachers across ten universities were analysed using structur...

K-core sparsification for intracommunity edges (KSI) for efficient and scalable community detection in complex networks

Community detection in complex networks often suffers from high computational cost and degraded community quality when graph reduction techniques excessively remove structurally important connections. To address this issue, this study proposes K-Core Sparsification for Intracommu...

BiGCNG: Bi-Path Graph Convolutional Neural Network with Gate Fusion for Person–Job Fit

Person–Job Fit (PJF) serves as a core task of intelligent recruitment recommendation. However, existing graph-based PJF models rely on a fixed, single-path aggregation scheme, thereby failing to simultaneously capture global interaction statistics and local competency-matching si...

Breaking the barrier: exercise preferences and motivational factors in stressed Chinese secondary school students

This study explores the motivations, barriers, and exercise preferences among Chinese secondary school students experiencing psychological stress. Semi-structured interviews were conducted with 29 adolescent students, and a deductive analysis was employed to identify key themes r...

Self-reported sports participation is associated with Y-Balance performance and centre-of-pressure measures in young adults

Abstract This exploratory cross-sectional study examined associations between a study-specific self-reported sports-participation category and balance measures in 65 healthy young adults, including 32 participants in the sports-participation group and 33 in the non-sports-partici...

Stethoscope disinfection practices among doctors: knowledge, attitudes, barriers, and acceptance of UVC technology

Abstract Background Stethoscopes are widely used across multiple patients and can serve as reservoirs of healthcare-associated infections if not disinfected. This study assessed doctors’ knowledge, attitudes and practices regarding stethoscope disinfection, perceived barriers, aw...

Acceptability and Willingness to Use the “CaknaStrok” Mobile Health Application and Associated Factors Among Informal Caregivers of Post-Stroke Patients in Malaysia: Protocol for an Explanatory Sequential Mixed-Methods Study

Background: Stroke is the third leading cause of death and a major cause of long-term disability in Malaysia, where the continuity of post-stroke care depends heavily on unpaid, untrained informal family caregivers. These caregivers face a well-documented “discharge cliff,” assum...

Navigating Psychological Vulnerabilities: A Qualitative Exploration of Gifted and Talented Students’ and School Counsellors’ Perspectives in Malaysia

This qualitative study explored the psychological vulnerabilities of gifted and talented students in Malaysia. Within a constructivist paradigm, semi-structured interviews were conducted with ten gifted and talented students (IQ >130) and five school counsellors. Reflexive themat...

Cellular Senescence and Immune Dysregulation in Acute-on-Chronic Liver Failure: A Case Report Integrating Single-Cell and Spatial Transcriptomic Profiling
