BIFURCATIONS AND EXACT TRAVELING WAVE SOLUTIONS FOR A GENERALIZED KLEIN- GORDON EQUATION WITH BETA FRACTIONAL DERIVATIVES

In this paper, we consider the exact traveling wave solutions of the generalized Klein-Gordon equation with beta fractional derivatives. By using the bifurcation theory of dynamical systems, we derive the bifurcation behavior of its phase portraits under various parameter setting...

Prevalence and clinical outcomes of malnutrition in hospitalized patients: a real-world study using a stepwise screening-assessment pathway

Hospital malnutrition is associated with adverse clinical outcomes, yet real-world evidence distinguishing nutritional risk screening from diagnostic assessment remains limited. This study evaluated a stepwise NRS2002-based screening and assessment pathway and examined associatio...

Evaluation of Mass Housing Quality in Ilorin Metropolis, Kwara State, Nigeria

The study evaluates the housing quality of selected mass housing estates in Ilorin Metropolis, Kwara State, Nigeria, with emphasis on housing and neighbourhood characteristics and residents' perceptions of housing quality. The aim is to assess the quality of mass housing developm...

CTC-AttnNet: development and validation of an attention-based neural network for staging gastrointestinal malignancies

To develop and validate a noninvasive model for classifying T stage in gastrointestinal malignancies using circulating tumor cells (CTCs) and serum tumor markers and to compare the predictive value of CTCs with that of conventional tumor markers. This retrospective study included...

Optimizing the radiolytic degradation of aspirin and acetaminophen in aqueous solutions using a Rhodotron electron-beam accelerator and central composite design

The escalating pollution of limited freshwater resources by ECs represents a critical byproduct of modern industrialization. Pharmaceutical compounds, specifically NSAIDs like ACM and ASP, are frequently detected in aquatic environments because conventional wastewater treatment p...

Brain rare metastatic tumors: a clinicopathological analysis of 14 cases

As one of the most common types of malignant brain tumors, brain metastases are associated with poor clinical outcomes. Lung cancer, breast cancer, colorectal cancer, and renal cell carcinoma are the most frequent primary tumors causing brain metastases. This study explores the c...

Pilot validation of a piezo‑resistive gnathodynamometer for maximum voluntary bite force measurement in adults: a cross sectional comparative study

Maximum voluntary bite force (MVBF) is a key indicator of masticatory system function, influenced by cranio-mandibular biomechanics, neuromuscular coordination, and dental status. Conventional bite force devices, though widely used, are limited by their bulk and potential discomf...

Situation-dependent emotion regulation in Japanese university students: Crying alone or in the presence of others?

This study aimed to investigate everyday crying among Japanese university students using a questionnaire survey and to examine how the choice to cry in the presence of others or alone was influenced by the context of the crying episode. Analyses were conducted on data from 169 pa...

Kakeya and the Rain-Field Analogy: From Needle Rotation to Directional Residuals

Abstract We see rain, not needles. A storm presents many short trajectories at once:gravity pulls them, wind inclines them, turbulence disperses them, and terraindecides where their water can go. The classical Kakeya image presents somethingelse: a unit segment in every direction...

Circulating inflammatory biomarkers and antifungal susceptibility in Candida albicans vulvovaginal candidiasis: a retrospective observational cohort study

Vulvovaginal candidiasis (VVC) affects millions of women worldwide. The rates of antifungal resistance are increasing, which can complicate therapy. Whether circulating inflammatory biomarkers reflect antifungal susceptibility patterns in localized VVC remains unclear. In this st...

Intra-amniotic transplantation of APOM-modified BMSCs facilitates neural repair in spina bifida by improving vascular endothelial integrity

Spina bifida aperta (SBA) is the most common type of neural tube defects. Although advances in fetoscopy have enabled fetal surgery to offer significant advantages over postnatal repair, the therapeutic efficacy for motor function impairment remains limited. Previously, we observ...

Pulse number determines synaptic plasticity threshold during intermittent theta-burst magnetic stimulation

Repetitive transcranial magnetic stimulation (rTMS) is widely used to modulate cortical excitability in clinical and experimental settings. Previous work has established that 10 Hz repetitive magnetic stimulation (rMS) reliably induces excitatory synaptic plasticity in mouse ento...

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...

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...
