Trust, Information Appraisal, and Health Communication Behaviours Among People Living with Multiple Sclerosis

Background: People living with multiple sclerosis (MS) are increasingly turning to the Internet for information about their condition and its treatment. However, online health information varies widely in quality, and patients often lack the eHealth literacy needed to distinguish...

OSI Stack Redesign for Quantum Networks: Requirements, Technologies, Challenges, and Future Directions

Quantum communication is emerging as a foundation for next-generation networks, offering unprecedented capabilities in security, entanglement-based connectivity, and distributed computation. However, the classical Open Systems Interconnection (OSI) model, designed for determinist...

Therapeutic Management of Schistosomiasis in Pregnancy: A Comprehensive Review of Praziquantel Safety and Clinical Outcomes

Background/Objectives: Schistosomiasis affects about 250 million people globally, including an estimated 40 million women of reproductive age and over 10 million pregnant women each year. Praziquantel is a key component of schistosomiasis control and is recommended by the World H...

Bacterial adaptation to essential oils and their main compounds in food systems: mechanisms related to antibacterial resistance

Essential oils (EOs) are complex mixtures of volatile metabolites with strong biological properties. Their multi-target mechanisms confer rapid bactericidal activity, lowering the likelihood of resistance development compared to antibiotics. This review examines bacterial respons...

Evaluating parameter-efficient fine-tuning of large language models for sentiment analysis with bayesian optimization

The increasing volume of user-generated reviews and feedback available in digital format provides valuable insights across various domains. Sentiment analysis plays a crucial role in extracting opinions from textual data. Large Language Models (LLMs) have demonstrated exceptional...

Mathematical Physics Models of RLC Electrical Circuit with Generalized $\mathcal{M}$ Derivative

In this article, we develop a mathematical model of an RLC electrical circuit using the generalized truncated $\mathcal{M}$-derivative, which extends the concept of the classical $\mathcal{M}$-series. The resulting generalized $\mathcal{M}$-derivative RLC model is analyzed via th...

Optimal Control and Cost-Effectiveness Analysis of a Mathematical Model for Mastitis Dynamics in Dairy Cows

Mastitis remains one of the most important infectious diseases affecting dairy cows, with substantial consequences for animal health, milk production, and farm profitability. In this study, we extend a nonlinear SIRS–P compartmental model for mastitis transmission in dairy cows b...

Nurses’ Perceptions and Behaviors Regarding Climate Change and Health: A Correlational Study Aligned With Saudi Vision 2030

ABSTRACT Climate change is an escalating threat to population health, placing increasing pressure on healthcare systems. Nurses play a pivotal role in delivering climate‐resilient healthcare; however, evidence regarding their perceptions and climate‐related health behaviors in Sa...

Positive Solutions of a Fifth-Order Boundary Value Problem for Couple-Stress Porous-Channel Flow

In this paper, we study the existence of positive solutions for a nonlinear fifth-order boundary value problem arising from fully developed couple-stress fluid flow through a porous channel. Under a natural restriction relating the couple-stress and permeability parameters, the a...

Phyto-Mediated Versus Conventional Nanomaterials for Environmental Remediation: Surface Chemistry, Removal Mechanisms, Performance, and Sustainability

Nanomaterials have emerged as key platforms for environmental remediation owing to their tunable surface chemistry, high specific surface area, and multifunctional physicochemical properties. This review provides a critical comparison between conventional nanomaterials (CNMs) and...

Identification of a nanosecond isomer of $$^{164}$$Tb

Abstract This letter reports on the identification of a new isomeric state of $$^{164}$$ 164 Tb ( $$Z=65$$ Z = 65 , $$N=99$$ N = 99 ), which was measured with the DESPEC setup at the GSI Helmholtzzentrum für Schwerionenforschung GmbH following the first relativistic fragmentation...

Artificial Intelligence-Assisted Community Eye Screening in Primary Healthcare: A Prospective Multicentre Diagnostic Accuracy and Implementation Study

Background Artificial intelligence (AI)-assisted retinal screening may extend access to eye care in primary healthcare, but prospective evidence on diagnostic performance and implementation under routine community conditions remains limited. Methods We conducted a prospective mul...

Proportional Autoregressive Quasi-Lindley Half-Logistic Unit Process with Application in Modeling Crime Dynamics

The manuscript proposes a novel bounded proportional autoregressive (PAR) process based on the quasi-Lindley half-logistic unit (QHU) distribution, termed the QHU-PAR(1) process. Fundamental probabilistic properties of the process are established, including its Markov structure,...

Smoking Cessation Knowledge among Community Pharmacists in Saudi Arabia

Introduction Tobacco use remains one of the most pressing global public health challenges, contributing substantially to the incidence of preventable diseases and premature mortality. In Saudi Arabia, tobacco consumption continues to rise, with an estimated 21.4% of adults identi...

Bioactive goldenseal (Hydrastis canadensis) fraction suppresses multidrug-resistant Pseudomonas aeruginosa in a rat burn wound model: oral and topical administration

Abstract Multidrug-resistant (MDR) Pseudomonas aeruginosa is a prominent pathogen implicated in burn wound infections, creating substantial therapeutic obstacles due to its antibiotic resistance and enhanced virulence mediated by quorum sensing (QS). This study explored the anti-...

Development of efficient finite population mean estimators using transformed auxiliary variables and hierarchical clustering-based stratification
