Burden of CNS neoplasms in the Middle East and North Africa from 1990 to 2023, with projections to 2050

Central nervous system (CNS) neoplasms are uncommon but highly consequential malignancies that account for substantial neurological disability and premature mortality. The Middle East and North Africa (MENA) region is marked by rapid population growth, aging, and uneven health sy...

Cell-free DNA fragmentomics and epigenomic profiling in hematologic malignancies: current evidence, translational limitations, and future directions

Mutation-based liquid biopsy supports diagnosis and disease monitoring in hematologic malignancies, but interpretation of plasma variants may be complicated by clonal hematopoiesis, treatment-related changes, and nonmalignant blood-cell turnover. This structured narrative review...

Comparative Analysis of Multimodal GANs for Cross‐Modal Information Retrieval

ABSTRACT Cross‐modal information systems have emerged as an important area of research that enables information retrieval in different modalities such as text, image and audio. Existing Cross‐modal retrieval methods focus on semantic consistency between modalities but rarely cons...

Transforming entrepreneurial intentions to action: a serial mediation model of entrepreneurial alertness and entrepreneurial self-efficacy

Purpose The specific mechanisms that transform entrepreneurs’ intentions into realized entrepreneurial behaviors remain a novel subject of ongoing investigation. Therefore, achieving insights into this process will be critical for expanding theory and informing practices. Further...

A Novel Weighted Log-Kumaraswamy Distribution: Mathematical Characterization, Statistical Inference, and Reliability Applications

Primary technique: Construction of a new Weighted Log-Kumaraswamy lifetime distribution using the weighted general family of distributions. In this paper, a new three-parameter lifetime model, called the Weighted Log-Kumaraswamy Distribution (WLKD), is proposed by incorporating t...

Patterns and drivers of beta diversity of Asteraceae across Africa: A taxonomic and phylogenetic approach

Unravelling the spatial and temporal dynamics of biodiversity is a central goal in ecology and evolutionary biology, requiring an integration of taxonomic and phylogenetic beta-diversity. However, a lack of comprehensive studies at continental scales for major ecologically divers...

Developing innovative models to improve ease of access and outcomes of rehabilitation services in rural communities: An integrative narrative review

Background Rehabilitation services in rural areas face persistent barriers such as geographic isolation, limited infrastructure, and resource constraints, which significantly impact patient access and outcomes. Objective This study investigates innovative models designed to impro...

ECO-EDGE: joint DAG offloading and fabric routing in Multi-AP MEC via conic optimization

Mobile Edge Computing (MEC) enables low-latency services by migrating computational resources closer to end-users. However, as mobile workloads increasingly adopt complex Directed Acyclic Graph (DAG) topologies, system performance is strongly affected by interdependent data shuff...

Numerical analysis of melting heat transfer in stratified Casson nanofluid flow over an inclined wedge for energy-efficient thermal systems

Purpose Given the diverse applications of nanoparticles, blood transport and stratified flow in medical and industrial domains, this study was conducted. Design/methodology/approach Nonlinear thermal stratification is used to capture realistic, high-gradient thermal environments...

Arabic Multimodal Dataset for Aspect-Based Sentiment Analysis

Multimodal sentiment analysis (MSA) has attracted growing interest among researchers in recent years, as multimodal user-generated content (e.g., text and images) has become increasingly common on the Internet. In Aspect-Based Sentiment Analysis (ABSA), multimodal data can provid...

Bavachin Attenuates Cognitive Impairment in Scopolamine‐Induced Amnesia: Behavioral, Biochemical and Molecular Insights

ABSTRACT Cholinergic dysfunction is a key feature of cognitive impairment, and currently available acetylcholinesterase (AChE) inhibitors provide limited symptomatic benefit and are often associated with adverse effects. This study evaluated the cognitive‐protective effects of ba...

Population pharmacokinetics modeling of albendazole and its active metabolite, albendazole sulfoxide in mass drug administration against lymphatic filariasis

ABSTRACT Albendazole (ALB), a benzimidazole antiparasitic, is widely used in mass drug administration (MDA) campaigns against lymphatic filariasis (LF). It is rapidly metabolized to its active form, albendazole sulfoxide (ALB-OX), which exhibits considerable interindividual varia...

Does ESG Disclosure Reduce Firm Risk in Saudi Arabia? Dynamic System GMM Evidence from Tadawul-Listed Companies
