Comparative genomic and gene expression study of Dirigent genes in genus Dendrobium: a bioinformatics analysis

Dirigent (DIR) proteins guide lignan and lignin formation and play important roles in plant defense and stress responses. Although genome assemblies have been completed for several Dendrobium species, the functional characterization and expression patterns of DIR genes in this ge...

The effect of Roy adaptation model-based education on self-care and coping in patients with plaster casts: a single-blind randomized controlled trial

Patients with orthopedic conditions undergoing plaster treatment experience both physical limitations and psychosocial stressors. These challenges may hinder self-care practices and adaptive coping strategies. The Roy adaptation model, by focusing on promoting holistic adaptation...

Ibn Khaldun as an Exegete: Critical Method and Epistemic Integration in the Muqaddimah

قلّما يُذكر عبد الرحمن بن خلدون (ت 808هـ) إلا مقروناً بريادته في علم العمران، مع أن جانباً آخر من فكره لا يقلّ عمقاً عن ذلك، وهو اشتغاله بالتفسير وعلوم القرآن. يتتبع هذا البحث ما أورده ابن خلدون في «مقدمته» من فصول عن تاريخ التفسير وأصنافه ومناهج أهله، ويحاول أن يبيّن أن هذا الاش...

The Impact of Mindfulness on Reducing Math Anxiety and Enhancing Mathematical Performance

هدفت هذه الدراسة إلى الكشف عن أثر اليقظة الذهنية في خفض قلق الرياضيات وتحسين الأداء الرياضي لدى طلبة المرحلة الثانوية في المدرسة التكنولوجية بمدينة رهط في منطقة النقب. وانطلقت الدراسة من أهمية العوامل النفسية والانفعالية في تعلم الرياضيات، وبخاصة أن قلق الرياضيات يعد من أبرز العو...

Registry Descriptions Go Stale Unevenly: An 89-Day Measurement of Model Context Protocol Drift, and Why Drift-Ranked Re-Auditing Under-Covers It

A longitudinal measurement of description staleness in the official Model Context Protocol (MCP) registry. Security studies of the MCP ecosystem each audit a registry at a single point in time; none reports how long the descriptions they judged stay current, which is a necessary...

Development of optimization-based algorithms for radiation source localization in nuclear emergencies

Accurate radiation source localization is a fundamental requirement for nuclear emergency response, environmental radiation monitoring, radioactive waste management, and homeland security. However, reliable localization remains challenging because of measurement uncertainty, back...

Wavelet-derived periodic variability and regional differences of surface ozone in southeastern Nigeria from 2002 to 2023

This study investigates the spatiotemporal variability of surface ozone across Southeastern Nigeria (2002–2023) using Continuous Wavelet Transform (CWT), a time–frequency method that detects localized oscillations and long-term cycles. Ten representative stations were selected to...

High-accuracy lung region segmentation and injury classification using deep networks

This study developed and evaluated a hybrid deep learning framework for automated lung segmentation and multi-class severity classification in chest CT scans, addressing key methodological gaps including heterogeneous dataset labeling, pseudo-label bias in segmentation, limited i...

Sustainable intensification of pigeon pea-turmeric intercropping to optimize turmeric population density for enhancing productivity, and economic profitability

Achieving sustainable intensification of cropping system to meet rising food and nutritional demands remains a significant challenge in many developing countries, particularly where smallholder farmers cultivate highly constrained landholding. In such contexts, intercropping offe...

Evaluation of the corrosion of metal-based containers in contact with molten salts at high temperature under inert atmosphere

The reliable deployment of high-temperature thermal energy storage (TES) systems in concentrated solar power (CSP) plants requires an accurate assessment of material compatibility under realistic operating conditions. However, conventional corrosion testing in air atmosphere does...

Gendered embodiment of sedentary behaviour and its impact on mental wellbeing in physiotherapy higher education: a sequential mixed methods study

Prolonged sedentary behaviour (SB) among university students is a growing concern, yet its impact on mental wellbeing (MWB) cannot be fully understood without considering its embodied nature: how it is experienced through the body in relation to social expectations. This study em...

RNAi-based therapeutics targeting the F gene in human metapneumovirus: An in-silico approach

Background: Human metapneumovirus (HMPV) is a major cause of acute respiratory tract infections, particularly in young children, older adults, and immunocompromised individuals. Despite its significant clinical burden, no approved antiviral therapies or vaccines are currently ava...

They Did Not Find a Flaw in The Text

This paper develops a framework for diagnosing a specific and underexamined failure in the interpretation of ancient texts: the silent transfer of interpretive authority from an upstream text to a downstream conceptual framework. The core claim is that later interpretive apparatu...

Quantifying vaccination thresholds and roll-out delays in an influenza transmission model with waning and immune boosting

This study develops and analyzes an SVIRLQS epidemiological model to investigate the combined effects of vaccination, waning immunity, immune boosting, and secondary infections on disease transmission dynamics. Understanding these mechanisms is important because immunity acquired...

Assessment of natural and anthropogenic radionuclides in marine sediments around the state of Qatar

Marine sediments in the Arabian Gulf serve as long-term sinks for both natural and anthropogenic radionuclides; however, comprehensive baseline data for Qatar’s coastline remain limited. This study focuses on determining the natural radioactivity levels in sediment around the Qat...

Multi-Backbone U-Net segmentation and interpretable hybrid deep learning classification for lung cancer detection in chest CT images

Lung cancer remains the leading cause of cancer-related mortality worldwide, and its early and accurate diagnosis from chest CT imaging is complicated by overlapping radiological features between benign and malignant lesions, as well as by the limited cross-institution validation...

The Who as a Modal Category

A standing statement of the first categorial determination of Ethical Ontology: that the who is a modal category of being. The question is what distinguishes someone from something. Two candidate answers are eliminated before any positive claim is made. Numerical identity individ...

The TLR9-CXCL2 complex orchestrates mitochondrial DNA-driven regulatory B cell dysfunction in acute lung injury

Acute lung injury (ALI)/Acute respiratory distress syndrome (ARDS) is a lethal condition driven by unresolved inflammation. Circulating mitochondrial DNA (mtDNA) acts as a potent damage-associated molecular pattern, yet its direct role in disrupting adaptive immune checkpoints re...

Integrated serum and synovial biomarker profiling reveals inflammatory and cartilage remodeling signatures in age-restricted knee osteoarthritis

Knee osteoarthritis (OA) is a complex disease characterized by inflammation, cartilage degeneration, and tissue remodeling. Although many biomarkers have been investigated, the combined biological significance of systemic and local biomarkers is not fully understood. This study a...

Serum homocysteine as a novel biomarker for predicting intestinal necrosis in patients with bowel obstruction: a prospective observational study

We evaluated the diagnostic accuracy of serum homocysteine (HCY) for predicting intestinal necrosis in patients with bowel obstruction and compared its performance with conventional inflammatory biomarkers. This prospective observational study enrolled consecutive patients presen...
