Article Citation - WoS: 5Component Importance in Coherent Systems With Exchangeable Components(Cambridge Univ Press, 2015) Eryilmaz, SerkanThis paper is concerned with the Birnbaum importance measure of a component in a binary coherent system. A representation for the Birnbaum importance of a component is obtained when the system consists of exchangeable dependent components. The results are closely related to the concept of the signature of a coherent system. Some examples are presented to illustrate the results.Article Citation - WoS: 10Citation - Scopus: 9Cohomology of Sheaves of Frechet Algebras and Spectral Theory(Pleiades Publishing inc, 2005) Dosiev, AAWe propose a holomorpbic functional calculus for a noncommutative operator family generating a supernilpotent Lie subalgebra. This calculus extends Taylor's holomorphic functional calculus.Article Citation - WoS: 2Citation - Scopus: 2Low Carbon Architectural Design(Gazi Univ, 2018) Balku, Saziye; Bal Kocyigit, Filiz; Architecture; Energy Systems EngineeringTendency towards sustainable energy resources is increasing and leading engineers and architects make joint efforts. Renewable energy potential present in nature can be used more efficiently so that while energy consumption is reducing, rate of energy gain, on the other hand, increases by architectural design methods. A sailing club in Golbasi, Ankara is designed as a low carbon building for optimum usage of solar and wind energy. It can be concluded using an energy efficient architectural design for a building before its construction makes it possible to meet the electrical and heat energy requirements at minimum cost and environmental friendly.Article Citation - WoS: 11Citation - Scopus: 15A Study on the Performance Evaluation of Wavelet Decomposition in Transient-Based Radio Frequency Fingerprinting of Bluetooth Devices(Wiley, 2022) Almashaqbeh, Hemam; Dalveren, Yaser; Kara, AliRadio frequency fingerprinting (RFF) is used as a physical-layer security method to provide security in wireless networks. Basically, it exploits the distinctive features (fingerprints) extracted from the physical waveforms emitted from radio devices in the network. One of the major challenges in RFF is to create robust features forming the fingerprints of radio devices. Here, dual-tree complex wavelet transform (DT-CWT) provides an accurate way of extracting those robust features. However, its performance on the RFF of Bluetooth transients which fall into narrowband signaling has not been reported yet. Therefore, this study examines the performance of DT-CWT features on the use of transient-based RFF of Bluetooth devices. Initially, experimentally collected Bluetooth transients from different smartphones are decomposed by DT-CWT. Then, the characteristics and statistics of the wavelet domain signal are exploited to create robust features. Next, the support vector machine (SVM) is used to classify the smartphones. The classification accuracy is demonstrated by varying channel signal-to-noise ratio (SNR) and the size of transient duration. Results show that reasonable accuracy can be achieved (lower bound of 88%) even with short transient duration (1024 samples) at low SNRs (0-5 dB).Article Citation - WoS: 4Citation - Scopus: 4Integrating Family-Centered Care To Child Health and Diseases Nursing Course Via Distance Education(Taylor & Francis inc, 2023) Ozbay, Sevil Cinar; Ozbay, Ozkan; Boztepe, HandanThe aim of this study was to determine the impact of an online Child Health and Diseases Nursing course emphasizing family-centered care upon the perceptions of nursing students toward family-centered care. A one-group pretest-posttest model was used in this study. The research participants consisted of 88 students studying at X University, Faculty of Health Sciences, Department of Nursing. While 67.1% of the students stated that there were obstacles in implementing family-centered care, 73.9% stated that there were no facilitating elements in implementing of family-centered care. A statistically significant difference was found between the mean scores of the students' posttest family-centered care attitude and parents' attitude at the end of the training. This study provides insights into family-centered care, which could be used in crafting policies and interventions in nursing education in Turkey. Such insights could foster positive perceptions of family-centered care among student nurses.Article Knee Hyperextension in Chronic Stroke: Associated Biomechanical and Neuromuscular Factors(Elsevier Sci Ltd, 2025) Korkusuz, Sueleyman; Korkusuz, Busra Seckinogullari; Ozgoren, Nihat; Aritan, Serdar; Ceren, Ali Naim; Topcuoglu, Mehmet Akif; Balkan, Ayla FilBackground: This study aimed to determine the gait phase in which knee hyperextension occurs in stroke patients and to investigate the factors associated with knee hyperextension. Methods: This study included 30 stroke patients aged between 40 and 70 years with maximum knee hyperextension during the stance phase of gait. Muscle strength was evaluated with manual muscle test, and muscle tone was assessed with the Modified Ashworth Scale. Kinematic evaluation of the patients was made using the motion analysis system. Additionally, categorisation was made according to the stance phase of gait, where knee hyperextension was at its highest. Findings: A weak relationship was found between maximum knee hyperextension angle and gastrocnemius spasticity, a moderate relationship between knee flexor muscle strength, and a moderate relationship between ankle dorsiflexor muscle strength. In addition, a weak relationship was found between the maximum knee hyperextension and pelvic retraction angles. According to this clustering, it was observed that 66.67 % of the participants (20 people) showed maximum knee hyperextension in the single support phase. It was observed that the participants who had maximum knee hyperextension, especially after the mid-stance phase, had higher mean gastrocnemius spasticity. It was also observed that participants in Cluster 4, with a greater amount of maximum knee hyperextension, had the worst clinical parameters. Interpretation: Our study observed that the degree of maximum knee hyperextension was related to knee flexor and ankle dorsiflexor muscle strengths, gastrocnemius spasticity and pelvic retraction. As clinical parameters worsened, maximum knee hyperextension was thought to occur late in the stance phase.

As universities are facing the challenge of promoting internationalization and mobility in students and teachers, they have to decide how to help their students in developing these skills as well as increase their awareness on the cultural differences in multinational settings. After a long trajectory of participation in multinational educational experiences, the authors launched a survey to check if their previous findings on the preferred soft skills by educational experts and managers still remain valid after 5 years. Another goal of the study was the analysis of the link between preference for specific soft skills and cultural background in each country as characterized by Hofstede's indicators. The data collected from 123 experts from 45 different countries have confirmed the existence of a stable core set of preferred soft skills at global level and also for European countries. Results have also shown links between specific cultural indicators and preference for some soft skills.Article Citation - Scopus: 1Maintaining Software Through Bit-Parallelism and Hashing the Parameterized q-grams(Univ Osijek, Tech Fac, 2012) Prasad, Rajesh; Agarwal, Suneeta; Misra, Sanjay; Sharma, Anuj Kumar; Singh, Alok; Computer EngineeringIn the software maintenance, it is often required to find duplicity present in the codes. Two code fragments are equivalent, if one can be transformed into the other via consistent renaming of identifiers, literals and variables. This equivalency can be detected by parameterized string matching. In this matching, a given pattern is said to match with a substring of the text, if there exists a one-to-one correspondence between symbols of and symbols of. In this paper, we propose an efficient algorithm for this problem by using both the overlapping and non-overlapping q-gram. We show the effect of running time of the algorithm on increasing the duplicity present in the code.Article Discussions on Perturbed Quasi-Metric Spaces(Yokohama Publishing, 2025) Karapinar, ErdalThe main goal of this manuscript is to introduce the notion of perturbed quasi-metric spaces.

Transcatheter aortic valve implantation (TAVI) has been developed as a therapy choice for inoperable, high-, or intermediate-risk surgical patients with severe aortic stenosis (AS). Objective: To evaluate the impact of DM and hemoglobin A1c (HbA1c) on outcomes and survival after TAVI. Methods: Five hundred and fifty-two symptomatic severe AS patients who underwent TAVI, of whom 164 (29.7%) had DM, were included in this retrospective study. Follow-up was performed after 30 days, six months, and annually. Results: The device success and risks of procedural-related complications were similar between patients with and without DM, except for acute kidney injury, which was more frequent in the DM group (2.4% vs. 0%, P=0.021). In-hospital and first-year mortality were similar between the groups (4.9% vs. 3.6%, P=0.490 and 15.0% vs. 11.2%, P=0.282, respectively). There was a statistical difference between HbA1c >= 6.5 and HbA1c <= 6.49 groups in total mortality (34.4% vs. 15.8%, P<0.001, respectively). The only independent predictors were Society of Thoracic Surgeons score (hazard ratio [HR] 1.28, 95% confidence interval [CI] 1.09-1.51; P=0.003) and HbA1c level >= 6.5 (HR 10.78, 95% CI 2.58-21.50; P=0.003) in multivariable logistic regression analysis. Conclusion: In this study, we conclude that DM was not correlated with an increased mortality risk or complication rates after TAVI. Also, it was shown that mortality was higher in patients with HbA1c >= 6.5, and it was an independent predictor for long-term mortality.
