Diagnostic performance of Baermann technique, urine-ELISA, stool-PCR and Strongyloides IgG4 rapid test for diagnosis of strongyloidiasis: a study protocol

Strongyloidiasis is caused by a parasitic worm, primarily Strongyloides stercoralis . In rural settings of Côte d’Ivoire, parasitological surveys have revealed that the prevalence of S. stercoralis infection can reach up to 50%. The World Health Organization has included S. sterc...

Empirical analysis of algorithmic components for improved performance in a baseline genetic algorithm selection hyper-heuristic

Selection hyper-heuristics represent high-level search algorithms that dynamically select and apply lower-level heuristics to solve various optimization problems. They encompass numerous algorithmic components such as heuristic selection, move acceptance, feedback, and parameter...

Triple band Yagi antenna design and performance prediction for next generation (6G) wireless applications using supervised regression models

This study presents a high-performance Yagi antenna designed for sub-terahertz (sub-THz) and terahertz (THz) wireless communication applications, addressing the growing demands of emerging technologies such as high-resolution imaging, short-range secure communication, sensing, sp...

Familiness as a dynamic relational capability: a mechanism-based framework of succession in family firms

Purpose This study aims to develop an integrative, mechanism-based framework explaining how familiness is enacted as a dynamic relational capability during family firm succession. It addresses the fragmented nature of existing literature by shifting the conceptual focus from stat...

Gut microbiome composition and plasma cytokines in acute leukaemia in relation to chemotherapy

Abstract Background: The gut microbiome and cytokines are involved in maintaining immune homeostasis and may influence the prognosis and complications experienced by acute leukaemia (AL) patients receiving chemotherapy. Methodology: This longitudinal study analysed blood and stoo...

Chemical Profiling and Persistence of Gasoline Residues on Natural and Synthetic Porous Substrates under Tropical Weathering Conditions

Understanding the persistence of gasoline residues on porous substrates is fundamental to arson investigations, which may provide critical evidence of malicious intent through the identification of ignitable liquid residues (ILRs). In forensic practice, delays between fire suppre...

Sustainable mineral processing risk analysis based initial settling rates prediction using enhanced machine learning models

Abstract The primary contamination concern of mineral processing tailings (MPT) is the leaching of hazardous substances into the environment. The literature indicates that MPT requires effective flocculation and polymer-assisted dewatering to ensure its disposal does not cause en...

Morphological Engineering of Electrospun Recycled Polyethylene Terephthalate (r-PET) Nanofibrous Membranes for Sustainable Air Filtration: A Critical Review

The growing demand for high-performance air filtration materials, coupled with increasing concerns over plastic waste accumulation, has accelerated interest in sustainable filtration technologies. Recycled polyethylene terephthalate (r-PET) has emerged as a promising feedstock fo...

A qualitative study on feeding experiences among caregivers of children with cerebral palsy requiring food texture modification

Background and purpose Children with cerebral palsy often experience feeding difficulties that require food texture modification and are highly dependent on their caregivers, which commonly lead to malnutrition. This study aimed to explore caregiver's current practices, perceptio...

Effects of Tabata training on physical fitness and mental health-related outcomes in children and adolescents: a systematic review and multilevel meta-analysis

Tabata training is a time-efficient form of high-intensity interval training, typically characterized by repeated 20-s bouts of high-intensity exercise interspersed with 10-s recovery periods. Although HIIT has been studied in children and adolescents, the specific effects of Tab...

Knowledge, attitude, and practice of sustainable management of single-use plastic waste among laboratory users

Single-use plastics (SUPs) are essential in laboratory settings for sterility and efficiency, yet their life cycle poses significant environmental and health risks. In Malaysia, sustainable practices for laboratory SUPs remain inadequately implemented. This study examines the kno...

The impact of geopolitical risk on energy and precious metal commodity markets using the DCC-GARCH MIDAS model

Purpose This study aims to investigate the impact of geopolitical risk on selected energy and precious metal commodities, namely WTI crude oil, Brent crude oil, natural gas, gold and silver. Design/methodology/approach The study uses a Dynamic Conditional Correlation Generalized...

The Potential Role of Amyloid Precursor Protein Fragments as a Screening Tool for Mild Cognitive Impairment

ABSTRACT Background Mild cognitive impairment (MCI) is a transitional stage between normal aging and dementia, in which early detection is essential. Urinary amyloid precursor protein (APP) fragments have been proposed as a non‐invasive biomarker, but their diagnostic value in el...

Cross-sectional associations of generative AI acceptance with self-efficacy and well-being among students recruited from seven Chinese universities

Generative artificial intelligence (AI) is increasingly used in higher education, but its associations with students’ broader psychological outcomes remain uncertain. This cross-sectional study examined generative AI acceptance, general self-efficacy, and well-being among 495 stu...

Translation and Validation of the Job Factor Questionnaire (JFQ) and Quick Exposure Check (QEC) into Malay Language for Small and Medium Food Manufacturing Industries (SME)

Reliable assessment of ergonomic and job-related risk factors requires tools that are linguistically, culturally, and contextually appropriate. This study translated, culturally adapted, and preliminarily evaluated Malay versions of the Job Factor Questionnaire (JFQ) and Quick Ex...

Human health risk assessment of PM 2.5 -bound heavy metals during a haze season in a semi‑urban agricultural area of Northern Thailand

This study assessed PM2.5-bound heavy metals (Cd, Pb, Cr, Cu, and Fe) and associated human health risks at a semi-urban-agricultural site in Phitsanulok, lower northern Thailand, during the 2024–2025 haze season. Enrichment factors (EF), geoaccumulation index (Igeo), and US EPA h...

Social network analysis and exponential random graph modelling of dengue spatiotemporal linkage networks in an urban Malaysian district

Dengue burden is increasingly concentrated in rapidly urbanising Asian cities, yet routine surveillance rarely captures fine-scale residential spatiotemporal co-occurrence. We characterised a case-level linkage network and identified sociodemographic and residential correlates of...

How perceived virtual-idol advertising appeals shape impulsive hotel booking intention: identity-activated persuasion in Saudi hospitality

Virtual idols – digitally created influencers with programmable personas and symbolic identities – are increasingly used in hospitality marketing, yet the processes through which their perceived advertising appeals shape booking-related responses remain insufficiently understood....

A spatial prototype-based framework for supporting peri-urban rural housing renewal and design
