From flood hazard to governable climate risk: An integrated framework for adaptive flood governance and the Flood Resilience and Sustainability Index (FRSI)

Climate change, urban expansion and ecosystem degradation are intensifying flood-risk management challenges worldwide. However, mitigation and recovery approaches remain fragmented across engineering, community adaptation, technology, governance and finance, limiting integrated a...

Surface and Interfacial Performance of Meldrum's Acid Derivatives for Aluminium Corrosion Inhibition in Alkaline Aluminium–Air Systems: Experimental Evaluation and Data–Driven Optimisation

ABSTRACT Aluminium–air batteries are low cost and have a high theoretical capacity, but the discharge efficiency and metal utilisation are restricted by the self‐corrosion of aluminium‐anode in alkaline electrolyte. In this study, two Meldrum's acid derivatives, thiophenecarboxal...

Unravelling the potential of date palm seeds for sustainable biodiesel production

The demand for sustainable energy is increasing due to interest in non-edible and waste-derived biodiesel. The date palm is a well-known plant and produces delicious fruit, with its seed often considered a byproduct. It’s a powerful source for natural oil production and has uniqu...

Thermo-mechanical performance of a TiAlN-coated micro-drill: effect of cutting speed and point angle on tool wear, cutting forces, and surface integrity

Abstract Cobalt Chromium Molybdenum (CoCrMo) alloys are essential for biomedical applications. However, their high hardness and low thermal conductivity severely hinder machinability. In micro-drilling, a geometric trade-off typically exists, where smaller point angles improve pe...

Diabetes-QMS Benchmark: A Multi-Level Industrial Dataset for Temporal Quality Monitoring and Calibration in Glucose and HbA1c Diagnostic-Device Manufacturing

Quality monitoring in diagnostic-device manufacturing requires datasets that preserve temporal, hierarchical, and calibration-related structure while avoiding information leakage in predictive evaluation. This study presents the Diabetes-QMS Benchmark, a de-identified multi-level...

Establishment of A New Bornean Genus of Gecarcinucidae (Crustacea: Brachyura), with Descriptions of Five New Species

Exploring adolescent bullying behaviour through the lens of family dynamics: an explorative study in Sarawak, Malaysia

Purpose Bullying among adolescents has become a persistent social issue in Malaysia, often linked to the quality of parenting and home environment. Recognising this concern, this study aims to explore the influence of parenting styles and family dynamics on adolescents’ bullying...

A multi-operator deep-learning approach to preserve visual integrity in content-aware image retargeting task

Abstract Preserving key visual elements during content-aware image retargeting is a challenging task as the integrity of prominent visual features are often destroyed while resizing images. Seam carving (SC) also known as content-aware image retargeting is a technique that adds o...

Gaussian process surrogate modelling and multi-objective optimization for energy-efficient CO2 capture using functionalized oil palm ash

Agricultural waste-derived adsorbents offer a sustainable approach for carbon capture while supporting biomass valorization. However, identifying operating conditions that simultaneously maximize CO 2 adsorption and minimize energy consumption remains challenging because adsorpti...

Quantifying the Impact of Adaptive Space and Inclusive Design on User Experience in Exhibition Halls: A Mixed-Methods Study in Wuhan, China

As exhibition halls become highly adaptable and technology-driven, they risk excluding aging demographics due to cognitive barriers. Addressing the empirical gap regarding this tension, this study validates a quantitative evaluation model based on the User-Space Interaction Frame...

Emotional intelligence and employee sustainable performance: the moderating role of digital organizational culture among women leaders

Purpose Grounded in the conservation of resources (COR) theory, this study aims to investigate the direct, moderating and mediating relationships between emotional intelligence, digital organizational culture and employee sustainable performance among women leaders in the Malaysi...

A simulation of hierarchical self organizing maps to predict the compressive strength of fly ash-based geopolymers

The complex, non-linear relationships between design parameters and compressive strength in fly ash-based geopolymer concretes (GPC) presents some challenges for classical empirical and statistical models. This study investigates the application of Hierarchical Self-Organizing Ma...

Mpox preventive practices and associated factors among adults in a travel-connected setting in Southern Sarawak, Malaysia: a community-based cross-sectional study

Mpox remains a relevant public health concern in non-endemic, travel-connected settings, where imported cases may occur despite the absence of sustained local transmission. Southern Sarawak, Malaysia, is a socio-demographically diverse region that includes Kuching District, a maj...

Macroeconomic Determinants of Housing Prices in Malaysia: Evidence from Time-Series Econometric Analysis

This study examines the effects of population, unemployment rate, construction costs, income per capita, and interest rates on housing prices using annual data from 1990 to 2024. Adopting time series econometric analyses, including stationarity, the ARDL model, VAR, Granger causa...

Evaluating soil CO₂ fluxes during the transition from peat swamp forest to an oil palm plantation

Conversion of peat swamp forests to oil palm plantations has significant implications for soil CO 2 emissions, but the magnitude of this impact remains highly uncertain. To evaluate the effects of this conversion on soil CO₂ fluxes, monthly measurements of soil CO₂ flux, environm...

An inference stage taxonomy-guided prompt framework for culturally aware generation of indigenous motifs
