Evaluation of a Structured Port Catheter Care Training Program for Nurses in Turkey: A Quasi-Experimental Study

Background: Port catheters are widely used in oncology care to provide safe long-term venous access; however, improper management may lead to complications such as infection, thrombosis, and extravasation. Nurses play a key role in preventing these complications through evidence-...

Hyperspectral Image Super-Resolution Using a Hybrid Method Combining Deep Learning and Sparse Representation

Background/Aim: Hyperspectral images provide rich spectral information but often suffer from low spatial resolution due to hardware limitations and long imaging distances. This study aims to enhance the spatial resolution of low-resolution hyperspectral images while preserving th...

Associations of the will to live with loneliness and psychological resilience in young and middle-aged Turkish adults

The will to live is a key motivational resource related to meaning, adaptation, and well-being. Most previous research has focused on older adults in Western countries, with limited evidence in younger populations and non-Western contexts. This study examined the relationships be...

Effects of virtual reality-based aerobic exercise versus traditional aerobic exercise training on physical fitness, functional capacity, and quality of life in individuals with Down syndrome: DOWNFIT (Down Syndrome Fitness Intervention Trial) randomized controlled trial

Purpose To compare the effects of virtual reality-based aerobic exercise (VR-AE) and traditional aerobic exercise (TAE) on on physical fitness, functional capacity, and quality of life (QoL) in adolescents with Down syndrome (DS).Methods Forty adolescents with DS (mean age 14.45...

Empathy and Violence Tendency: The Mediating Roles of Emotional Intelligence and Masculine Behaviour

Violence represents a significant psychosocial problem affecting both individuals and societies. This cross-sectional study examined the relationship between empathy and violence tendency and investigated the mediating roles of emotional intelligence, emotional regulation, and ma...

Evaluation of the accuracy and reproducibility of large language models (ChatGPT, DeepSeek, Gemini) in responding to patient-centered lipedema questions

Background Lipedema is a frequently misdiagnosed chronic condition that significantly impacts patients’ quality of life. As artificial intelligence (AI)-based large language models (LLMs) become increasingly integrated into healthcare communication, their accuracy and consistency...

Dynamic Behavior Modeling of Solenoid Valves Used for Proportional Fuel Control: PWM-Based Flow Rate Prediction

This study presents a predictive modeling framework for estimating transient flow rates in PWM-driven solenoid valves. Building on a previously validated dynamic model, the proposed framework enables flow prediction under varying process conditions and valve configurations. Flow...

The Role of Resilience in Relation to Depression, Anxiety, Stress, and Post-Traumatic Stress Symptoms Among Syrian Refugee Adolescents in Türkiye

Objectives: Mental health problems and post-traumatic stress symptoms are prevalent among adolescent refugees, yet little is known about the role of resilience in relation to these difficulties among Syrian adolescents. This study examined the unique contribution of resilience to...

On weighted inequalities for B -maximal operators

Let 1 < p < ∞ and w, v be two non-negative weight functions. In this paper, we provide a sufficient condition on w, v for the new maximal operator associated with the generalized translate operator Ty for each to be bounded from Lp,γ (v) to Lp,γ (w). Our condition is stronger, bu...

Comparative experimental and numerical investigation of engine-lubricant performance in hydrogen- and gasoline-fueled PFI SI engines

Hydrogen-fueled spark-ignition (SI) engines offer wide flammability limits, fast flame propagation, and carbon-free exhaust products, making them a promising route toward low-carbon transportation. However, their fast heat-release rates and elevated in-cylinder temperatures pose...

Chronotype, temporal eating patterns, and sleep behaviors among physically active university students: A cross-sectional study

Chronotype and meal timing are associated with sleep, yet their joint relationships remain understudied in physically active university students. This study investigated associations among chronotype, caloric intake timing, and sleep characteristics and hypothesized that later fi...

The Impact of Artificial Intelligence Development on Green Bond Issuance: Evidence From G20 Countries

The rapid advancements in artificial intelligence (AI) technologies are transforming the functioning of financial markets and significantly impacting the development of sustainable financing instruments. Green bonds, in particular, have become one of the fastest-growing capital m...
