Article Citation - WoS: 11Citation - Scopus: 11A Standard Benchmarking Suite for Structural Optimization Algorithms: Iscso 2016-2022(Elsevier Science inc, 2023) Azad, Saeid Kazemzadeh; Azad, Saeıd Kazemzadeh; Azad, Sina Kazemzadeh; Azad, Saeıd Kazemzadeh; Department of Civil Engineering; Department of Civil EngineeringBenchmarking is an essential part of developing efficient structural optimization techniques. Despite the advent of numerous metaheuristic techniques for solving truss optimization problems, benchmarking new algorithms is often carried out using a selection of classic test examples which are indeed unchallenging for contemporary sophisticated optimization algorithms. Furthermore, the limited optimization results available in the literature on new test examples are usually not accurately comparable. This is typically due to the lack of infromation about the performance of the investigated algorithms and the inconsistencies between the studies in terms of adopted test examples for benchmarking, optimization problem formulation, maximum number of objective function evaluations and other similar issues. Accordingly, there exists a need for developing new standard test suites composed of easily reproducible challenging test examples with rigorous and comparable performance evaluation results of algorithms on these test suites. To this end, the present work aims to propose a new baseline for benchmarking structural optimization algorithms, using a set of challenging sizing and shape optimization problems of truss structures selected from the international student competition in structural optimization (ISCSO) instances. The most recent six structural optimization examples from the ISCSO are tackled using a representative metaheuristic structural optimization algorithm. The statistical results of all the optimization runs using the proposed benchmarking suite are provided to pave the way for more rigorous benchmarking of structural optimization algorithms.Article Citation - WoS: 16Citation - Scopus: 16q-bernstein Polynomials of the Cauchy Kernel(Elsevier Science inc, 2008) Ostrovska, SofiyaDue to the fact that in the case q > 1, q-Bernstein polynomials are not positive linear operators on C[0, 1], the study of their approximation properties is essentially more difficult than that for 0 < q < 1. Despite the intensive research conducted in the area lately, the problem of describing the class of functions in C[0, 1] uniformly approximated by their q-Bernstein polynomials (q > 1) is still open. In this paper, the q-Bernstein polynomials B-n,B-q(f(a); z) of the Cauchy kernel f(a) = 1/(z - a), a is an element of C \ [0, 1] are found explicitly and their properties are investigated. In particular, it is proved that if q > 1, then polynomials B-n,B-q(f(a); z) converge to f(a) uniformly on any compact set K subset of {z : vertical bar z vertical bar < vertical bar a vertical bar}. This result is sharp in the following sense: on any set with an accumulation point in {z : vertical bar z vertical bar > vertical bar a vertical bar}, the sequence {B-n,B-q(f(a); z) is not even uniformly bounded.

One thousand twenty-four adult patients diagnosed with crush syndrome were analyzed. and outcomes were collected. A total of 9.8% of patients died during their hospital stay. Nonsurvivors were generally older, more likely to have preexisting chronic kidney disease, and faced more severe injuries and complications, including hypotension-shock, arrhythmias, elevated markers of renal dysfunction, and higher rates of acute kidney injury (AKI) and compartment syndrome. In addition, intensive care unit needs were higher. Multivariate analysis confirmed that age, injury severity, shock, high potassium, uric acid, and lactate levels on admission, development of AKI, compartment syndrome, and intensive care unit admission were significant predictors of mortality. Better disaster preparedness and improved health care infrastructure could be potential explanations for improved in-hospital mortality in the current era, as compared to previous earthquakes.Article Citation - WoS: 15Citation - Scopus: 17Improved Global Robust Stability of Interval Delayed Neural Networks Via Split Interval: Generalizations(Elsevier Science inc, 2008) Singh, VimaldThe problem of global robust stability of Hop field-type delayed neural networks with the intervalized network parameters is revisited. Recently, a computationally tractable, i.e., linear matrix inequality (LMI) based global robust stability criterion derived from an earlier criterion based on dividing the given interval into more that two intervals has been presented. In the present paper, generalizations, i.e., division of the given interval into m intervals (where m is an integer greater than or equal to 2) is considered and some new LMI-based global robust stability criteria are derived. It is shown that, in some cases, m = 2 may not suffice, i.e., m > 2 may be needed to realize the improvement. An example showing the effectiveness of the proposed generalization is given. The paper also provides a complete and systematic explanation of the "split interval" idea. (c) 2008 Elsevier Inc.

Evidence from a broad panel of advanced and emerging countries shows that an increase in credit growth is associated with a significant deterioration in the current account balance. When we examine the roles of the components of credit, we find that an increase in household credit causes a significant decline in the current account balance, whereas an increase in business loans has no significant effect. Therefore, our findings indicate that the significant negative impact of credit growth on the current account balance is driven by household credit. Furthermore, we show that total and household credit growth rates have a stronger negative effect on the current account balance for lower levels of financial depth. Our results suggest that targeted policy measures that curb household credit growth might be more effective to reduce external imbalances particularly at the early stages of financial deepening.Article Citation - WoS: 18Citation - Scopus: 21Musculoskeletal Pain, Related Factors, and Posture Profiles Among Adolescents: a Cross-Sectional Study From Turkey(Elsevier Science inc, 2021) Ozdemir, Serpil; Gencbas, Dercan; Tosun, Betul; Bebis, Hatice; Sinan, OzlemPurpose: The aim of the study was to evaluate musculoskeletal pain due to mechanical reasons and related risk factors in adolescents and to define posture profiles of adolescents. Design: A cross-sectional study. Methods: The study was conducted with 2221 adolescents between February 2015 and May 2015. The questionnaire used to collect data consisted of three parts: (1) descriptive characteristics of the participants, (2) pain assessment of 14 parts of the body, and (3) Back Pain and Body Posture Evaluation Instrument (BackPEI). Results: The prevalence of low back pain among the participants was 73.3% (n = 1,343), while the prevalence of back pain was 68.4% (n = 1,254). The participants attributed their pain to their poor sitting postures at school (38.1%, n = 847) and carrying school backpacks (84.1%, n = 1,713). There was a statistically significant difference in the physical activities of adolescents and the BackPEI score (z = 4.40; p = .001). Posture factors of the BackPEI score increased while school desk comfort score increased (Spearman's rho = 0.148; p = .001), but it decreased while the school grades of the adolescents increased (Spearman's rho [rho] = -0.161; p = .001). Conclusions: According to this study, body posture was related to musculoskeletal pain and was correlated with physical activities, school desk comfort, and school grades of the adolescents. It is suggested that correct posture and ergonomic positions should be taught to adolescents when using computers, carrying school backpacks, and sitting in school chairs to prevent musculoskeletal pain.

Methods: Eighty participants were randomly assigned to one of four groups: reflexology, progressive muscle relaxation (PMR) exercises, both (reflexology + PMR), or a control group. Data were collected with a general data collection form, Brief Pain and Fatigue inventories, and Multidimensional Quality-of-Life Scale-Cancer. Results: In reflexology and reflexology + PMR groups, a significant decrease in pain severity and fatigue and an increase in QoL were found (p < .05). In the PMR alone group, pain severity and fatigue decreased significantly (p < .05), but there was no significant change identified in QOL (p > .05). Conclusions: Reflexology and PMR exercises given to gynecologic cancer patients during chemotherapy were found to decrease pain and fatigue and increase QoL.

Design and methods: This descriptive, cross-sectional study was conducted with a sample of 347 parents of children with cleft lip/palate. Data were collected through face-to-face interviews with the parents between March 18 and September 4, 2023. The data collection tools included a sociodemographic data form, the Zarit Burden Interview, the Warwick-Edinburgh Mental Well-Being Scale, and the Satisfaction with Life Scale. Results: It was found that parents with a higher caregiving burden had lower levels of life satisfaction. Additionally, parents with higher life satisfaction reported better mental well-being. The findings indicated that as the caregiving burden increased, the mental well-being of the parents decreased. The results suggest that life satisfaction mitigates the negative impact of caregiving burden on mental well-being. Conclusion: These findings suggest that life satisfaction plays a significant mediating role in maintaining and supporting parents' mental health. Parents with higher life satisfaction appear to cope better with the challenges posed by caregiving burden, which in turn helps them maintain better mental well-being. Practice implications: The findings show that as the caregiving burden increases, both life satisfaction and mental well-being decrease. Therefore, it is crucial to develop practical interventions to support these parents. (c) 2024 Elsevier Inc.

The random deterioration in resistance of a component is defined through a stochastic process. We obtain lifetime distribution of a parallel system via classical probabilistic techniques. The lifetime distribution of a consecutive-k-out-of-n:F system is derived using the lifetime distribution of parallel systems and the concept of maximal signature. We also study the optimal replacement time for a parallel system. We present illustrative computational results using MATHCAD. (C) 2013 Elsevier Inc.
