Seasonal dynamics of proximate composition, fatty acid profile, and mineral content in muscle tissue of Diplodus annularis and Zosterisessor ophiocephalus fishes

Seasonal variability significantly affects nutritional quality and the dietary and commercial value of marine fish. This study includes an in-depth seasonal analysis of proximate composition, energetic content, fatty acid profile, and mineral content of Diplodus annularis and Zos...

CBT-ICU transformer: a clinician-behaviour-aware multimodal deep learning framework for early detection of critical care adverse events in MIMIC-IV

Early identification of clinical deterioration in intensive care units (ICUs) remains a major challenge despite the availability of large-scale electronic health records. Most existing models focus primarily on physiological measurements such as vital signs and laboratory results...

Why food stays contaminated: a COM-B framework analysis of child feeding practices in Dhaka’s informal settlements

Abstract Background Foodborne diseases are the major public health concerns in low- and middle-income countries, particularly during the complementary feeding period. Children become increasingly exposed to environmental pathogens at this age. Food hygiene during this period is c...

On the Stability of Fractional Non-Autonomous Evolution Equations with Impulsive Effects

This work addresses the Ulam–Hyers stability of mild solutions of fractional noninstantaneous evolution nonlinear equations subject to noninstantaneous impulses in the Banach space through an approach based on the measure of noncompactness. Mild solutions are formulated via opera...

Prevalence of Early Childhood Caries among 3–5-year-old Children in Qassim, Saudi Arabia: A Cross-sectional Study

Abstract Background: Early childhood caries (ECC) is one of the most common chronic conditions affecting young children and continues to represent an important public health challenge in Saudi Arabia. Population-based data on ECC in Qassim are limited. Objectives: To assess the p...

Heat transfer and entropy analysis of shaped nanoparticles in stratified binary nanofluid flow over an exponentially curved Riga surface

The problem of controlling heat transmission and flow efficiency in advanced engineering systems, such as aerospace thermal management and next-generation cooling devices, is critically hampered by energy losses due to friction and thermal irreversibility. This study addresses th...

Green Capital Transitions in the GCC: A Framework for Sustainable Financial Integration and Climate-Aligned Investment Growth

Green finance has emerged as a critical mechanism for aligning capital markets with climate and sustainability objectives, particularly as economies face mounting pressure to transition away from carbon-intensive growth models. In hydrocarbon-dependent regions such as the Gulf Co...

Public Awareness of Genetic Diseases, Preventive Screening, and Genetic Healthcare Services in the Qassim Region, Saudi Arabia: A Cross-Sectional Study

Background: Genetic diseases pose a significant public health issue in Saudi Arabia, driven by relatively high prevalence and factors such as consanguineous marriage. Increasing public awareness and understanding are crucial to improving prevention, early detection, and the use o...

Genetic Determinants of Milk Production Phenotypes in Dairy Goats: A Review

Dairy goats sustain milk production across marginal environments worldwide, yet genetic improvement of milk yield and composition remains slower than in cattle, constrained by smaller reference populations and limited functional validation. This review consolidates current eviden...

Theoretical Analysis of Androstenone Adsorption on Chimpanzee and Gorilla Olfactory Receptors (G‐Protein): Statistical Physics Modeling, Molecular Docking Simulation, and Thermodynamic Investigation

ABSTRACT An advanced theory based on statistical physics was applied to microscopically investigate androstenone adsorption and its relationship with olfactory perception in chimpanzees and gorillas. For this purpose, dose–response curves of androstenone on olfactory receptors of...

Physiological and transcriptional regulation of cadmium stress tolerance in ornamental pepper by silicon nanoparticles and melatonin

Nanotechnology has been established as a promising approach to improve heavy metal stress tolerance in horticultural crops. Melatonin (MT) is an emerging biostimulant for inducing stress resistance in plants. In this study, we evaluated the individual and combined effects of sili...

An Integrated explainable machine learning framework for pavement condition assessment and maintenance prioritization: A Saudi Arabian case study

Abstract Effective pavement condition assessment is critical for maintaining durable, safe, and well-performing road networks, particularly in arid regions such as Saudi Arabia, where heavy traffic loading, high temperatures, and surface distress accelerate pavement deterioration...

Detoxification of aflatoxin M1 by eight lactic acid bacteria strains, alone or in combination, as viable and heat-killed cells in PBS, MRS broth, and Karish cheese

Abstract Aflatoxin M1 (AFM1) in milk is a major public health concern. It is a hydroxylated metabolite of aflatoxin B1 (AFB1), formed in the liver of animals after ingestion of contaminated feed and subsequently excreted into milk. Biological techniques could be used to combat th...

Smoking-related knowledge, attitudes, and beliefs regarding cardiovascular and respiratory harms among health sciences students who currently smoke in Saudi universities

Tobacco smoking is a major preventable cause of cardiovascular and respiratory morbidity worldwide. Although conventional cigarettes are strongly linked to serious chronic diseases, e-cigarettes generally result in lower toxicant exposure than conventional cigarettes but are not...

Lipid accumulation product (LAP): a key indicator for metabolic dysregulation and inflammatory status in obesity

The Lipid Accumulation Product (LAP) is recognized as an indicator of lipid-induced cellular stress. While its predictive value for conditions like diabetes, liver disease, and metabolic syndrome is established, its specific correlations with individual metabolic and hematologica...

FedCogniBand: cognition-aware predictive bandwidth allocation for communication-limited federated learning

Federated Learning (FL) facilitates collaborative model training among dispersed clients while safeguarding data privacy; yet, its practical implementation is significantly hindered by substantial uplink bandwidth restrictions and notable data heterogeneity. Even though there hav...
