Editorial Citation - WoS: 5Citation - Scopus: 6Transcatheter Treatment Tricuspid Regurgitation by Valve-In Implantation With a Novel Balloon-Expandable Myval® Thv(Polish Cardiac Soc-polskie Towarzystwo Kardiologiczne, 2022) Ayhan, Huseyin; Karaduman, Bilge Duran; Keles, Telat; Bozkurt, Engin[No Abstract Available]Article Citation - WoS: 1Citation - Scopus: 4Fixed Point Theorems for Mappings With a Contractive Iterate at a Point in Modular Metric Spaces(House Book Science-casa Cartii Stiinta, 2022) Karapinar, Erdal; Aksoy, Umit; Fulga, Andreea; Erhan, Inci M.In this manuscript, we introduce two new types of contraction, namely, w-contraction and strong Sehgal w-contraction, in the framework of modular metric spaces. We indicate that under certain assumptions, such mappings possess a unique fixed point. For the sake of completeness, we consider examples and an application to matrix equations.Article Citation - WoS: 8Citation - Scopus: 8Thermoluminescence Properties of Zno Nanoparticles in the Temperature Range 10-300 K(Springer, 2016) Isik, M.; Yildirim, T.; Gasanly, N. M.Low-temperature thermoluminescence (TL) properties of ZnO nanoparticles grown by sol-gel method were investigated in the 10-300 K temperature range. TL glow curve obtained at 0.2 K/s constant heating rate exhibited one broad peak around 83 K. The observed peak was analyzed using curve fitting method to determine the activation energies of trapping center(s) responsible for glow curve. Analyses resulted in the presence of three peaks at 55, 85 and 118 K temperatures with activation energies of 12, 30 and 45 meV, respectively. Thermal cleaning process was applied to separate overlapped peaks and get an opportunity to increase the reliability of results obtained from curve fitting method. Heating rate dependence of glow curve was also studied for rates between 0.2 and 0.7 K/s. The shift of the peak maximum temperatures to higher values and decrease in peak height with heating rate were observed. Moreover, X-ray diffraction and scanning electron microscopy were used for structural characterization.Article Citation - WoS: 13Citation - Scopus: 14Coincidence Point Theorems on Quasi-Metric Spaces Via Simulation Functions and Applications To g-metric Spaces(Springer Basel Ag, 2018) Lopez de Hierro, A. F. Roldan; Karapinar, E.; O'Regan, D.In this paper, we present some coincidence point results in the framework of quasi-metric spaces using contractive conditions involving simulation functions. As consequences, we are able to particularize these results to a variety of situations including G-metric spaces. The results presented in this paper generalize and extend several comparable results in the existing literature. In addition, some examples are given.Editorial The Sixth International Workshop on Nonlinear Analysis and Its Applications Preface by the Guest Editors(Univ Belgrade, Fac Electrical Engineering, 2025) Karapinar, Erdal; Cvetkovic, Marija; Cirovic, Natasa A.Article Citation - WoS: 4Citation - Scopus: 5Physical Fitness and Maternal Psychosocial Status in Children With Autism Attending a Regular Physical Activity Program(Sage Publications inc, 2022) Sahan, Ayse Kubra; Ozturk, Nazan; Calik-Kutukcu, Ebru; Aksu, Hatice; Tunagur, Mustafa Tolga; Arikan, HulyaThe aim of this study was to compare physical fitness-related parameters in children with mild to moderate autism and their typically developing (TD) peers to determine maternal anxiety level and quality of life. Children with autism had significantly worse scores for all Munich Fitness Test (MFT) parameters except step test heart rate and had lower physical activity levels compared to the TD children (p < .05). There was no difference between groups in terms of postural deviations or maternal anxiety scores (p > .05). The MFT total score was associated with higher maternal quality of life scores (r = .605, p = .006). This study showed that despite participating in a regular physical activity program, children with mild to moderate autism have lower physical fitness and activity levels compared to their TD peers, whereas better physical fitness in children with autism has a positive effect on their mothers' quality of life.Article Citation - WoS: 19Citation - Scopus: 19Best Proximity Point Theorems for kt-types Cyclic Orbital Contraction Mappings(House Book Science-casa Cartii Stiinta, 2012) Karapinar, Erdal; Petrusel, Gabriela; Tas, Kenan; MathematicsIn this manuscript, three new KT-types cyclic orbital contractions are defined and some related best proximity point theorems are given. Also, the notion of KT-type cyclic orbital Meir-Keeler contraction is defined and some fixed point theorems for this class of mappings are proved. The results of this manuscript generalize some theorems, on the same subject, of several authors, such as Kirk-Srinavasan-Veeramani, Eldered-Veeramani and Karpagam-Agrawal.Article Citation - WoS: 16Citation - Scopus: 16Using Eye-Movement Events To Determine the Mental Workload of Surgical Residents(int Group Eye Movement Research, 2018) Dalveren, Gonca Gokce Menekse; Cagiltay, Nergiz ErcilThese days, eye-tracking is one of the promising technologies used in different fields such as aviation, arts, sports, psychology and driving for several purposes. Even though it is being used for health purposes, studies involving eye-tracking are rare in the field of endo-neurosurgery. This study aims to use this technology to promote our understanding of the effect related to computer-based instructional materials on mental workload of endo-neurosurgery residents. Four computer-based simulation scenarios are developed based on skill development requirements of endo-neurosurgery residents. Two of them were designed as general models and the other two as simulated surgical models. During these surgery procedures, in real settings, surgical residents need to use their both hands simultaneously to control the endoscope and the operational tool in a coordinated fashion. Therefore, to shed light on the participants' behaviors, these scenarios are performed with dominant-hand, non-dominant hand and, finally with both-hands using haptic interfaces. Twenty-three residents volunteered in this study. Their eye-movements were recorded while performing the scenarios. According to the results of this study, when performing the simulated surgical models, an increase in the participants' mental workload was recorded when compared to the other scenarios. Accordingly, it can be concluded that the eye-movements of surgical residents can provide insights about the anticipated level of difficulty about the skill-based tasks. This information might be very critical to properly design and organize instructional materials for endo-neurosurgery, and also to better guide and evaluate the progress of trainees in computer simulation-based skill training environments.Article Citation - WoS: 69Citation - Scopus: 71An Approach To Best Proximity Points Results Via Simulation Functions(Springer Basel Ag, 2017) Karapinar, Erdal; Khojasteh, FarshidIn this paper, we investigate of the existence of the best proximity points of certain mapping defined via simulation functions in the frame of complete metric spaces. We consider the uniqueness criteria for such mappings. The obtained results unify a number of the existing results on the topic in the literature.Article Citation - WoS: 11Citation - Scopus: 15The q-versions of the Bernstein Operator: From Mere Analogies To Further Developments(Springer Basel Ag, 2016) Ostrovska, SofiyaThe article exhibits a review of results on two popular q-versions of the Bernstein polynomials, namely, the LupaAY q-analogue and the q-Bernstein polynomials. Their similarities and distinctions are discussed.
