Evaluating airline service quality using a Pythagorean fuzzy multi-criteria group decision-making framework

Growing competition in the airline industry has made service quality evaluation an increasingly important yet complex Multi-Criteria Group Decision-Making (MCGDM) problem. Service quality depends on several interrelated attributes, and passenger or expert assessments are often su...

Profiles of self-reported emotional intelligence and cognitive emotion regulation strategies among university students: a latent profile analysis

Self-reported emotional intelligence (EI) is associated with psychological adjustment, but most studies of its links with emotion regulation (ER) are variable-centred. Students could differ in the configuration of EI dimensions (e.g., high emotion appraisal with low perceived reg...

Comparative evaluation of mass attenuation coefficients and energy absorption parameters in human tissues across a broad photon energy range

Reliable photon attenuation data are fundamental to medical physics for characterizing radiation transport, dose deposition, and shielding requirements within biological media. This study provides a comprehensive evaluation of the mass attenuation coefficient (MAC) across twelve...

Multilayer perceptron-assisted multi-objective optimization of an integrated cryogenic biogas upgrading system for simultaneous liquid CO2, hydrogen, power, heating, and cooling production

Using biogas in an integrated multi-generation system is one of the possible solutions for optimizing the utilization of renewable energy, minimizing environmental effects, and enhancing resource efficiency. In the current project, a new multi-product energy setup using biogas is...

The Impact of Preexisting Cardiac Implantable Electronic Devices on the Safety of Transcatheter Tricuspid Valve Interventions: A Systematic Review and Meta-Analysis

Background: Tricuspid regurgitation (TR) increases mortality but remains undertreated due to high surgical risks. Transcatheter tricuspid valve interventions (TTVI) offer safer alternatives, improving functional status and quality of life. However, many candidates for TTVI have t...

Intelligent neural network–based framework for Maxwell nanofluid flow with Soret–Dufour coupling and nonlinear thermal radiation

This study examined the optimization of the Levenberg–Marquardt backpropagation approach, which uses artificial neural networks, to calculate the interacting features of Soret and Dufour effects on convective Maxwell nanofluid flow through a porous surface with nonlinear thermal...

Unlocking Innovation in Hierarchical Contexts: Extending Componential Theory Through Employee Perspective

ABSTRACT Innovation is routinely named as a determinant of HR and organizational competitiveness, yet how the employees expected to produce it read the conditions surrounding them in the workplace has attracted little scrutiny—least of all in steeply hierarchical, non‐Western wor...

A study on the synthesis and characterization of maleate-functionalized Artemisia vulgaris hydrogel for Ni(II) adsorption from groundwater: mechanism, kinetics, and reusability

Life on Earth is at risk due to widespread pollution from industrialization and human activities. The presence of harmful heavy metal ions in drinking water sources is amongst the key pollutants that require immediate remediation. The seeds of the Artemisia vulgaris plant were us...

Synthetic Biology and Soft Robotics in Biohybrid Kidney Replacement: A Conceptual Framework and Translational Roadmap

ABSTRACT Background Chronic kidney disease necessitates safer, more continuous kidney replacement therapies (KRT), yet current dialysis and transplantation are constrained by intermittent treatment, organ scarcity, and immunosuppression‐related complications. Methods This concept...

AI-driven systems for advancing smart building infrastructure: An integrated review for energy management, occupant comfort, and cybernetics

The development of smart building infrastructure requires integrated approaches that balance energy efficiency, occupant well-being, and resilient control mechanisms. This study reviews the advanced computational systems, supporting three interconnected fields: cybernetic coordin...

Evidence-based evaluation of berberine in neurodegenerative diseases: targeting multiple signaling pathways and modulating neuroinflammation, oxidative stress, and apoptosis

Neurodegenerative diseases (NDs), such as Alzheimer’s disease (AD) and Parkinson’s disease (PD), are characterized by progressive neuronal loss, oxidative stress, mitochondrial dysfunction, and neuroinflammation. Novel neuroprotective drugs are urgently required since existing tr...

Buckling of carbon nanotubes using molecular dynamics simulation: Investigating the effect of boron doping by considering the interaction energy

This study investigates the atomic-scale stability and buckling behavior of boron-doped carbon nanotubes (CNTs) using molecular dynamics simulations. After equilibration in the NVT ensemble, we applied compressive deformation to evaluate the mechanical response and structural evo...
