Generalized product of fuzzy subgroups and t-level subgroups

Ray (Fuzzy Sets and Systems 105(1999)181-183) studied some results of the product of two fuzzy subsets and fuzzy subgroups. In this paper, Ray\u27s results will be generalized. Furthermore, we define a t-level subset and t-level subgroups, and then we study some of their properties

Moral pluralism on the trolley tracks: different normative principles are used for different reasons in justifying moral judgments

Due to copyright restrictions, the access to the full text of this article is only available via subscription.The psychological correlates of utilitarian choices in sacrificial moral dilemmas are contentious. In the literature, some research (Greene, et al., 2001) suggested that utilitarianism requires analytic thinking while other research (Kahane et al., 2015) showed that utilitarianism is correlated with psychopathy. In the present research, we looked at the relation of several normative views with analytic cognitive style (ACS), psychopathy and real-world utilitarianism in three Turkish samples. In Study 1 (n = 269), we used four ethical dilemmas and asked participants to select one normative principle as the grounds for their judgment in the dilemma: fatalism, virtue ethics, utilitarianism, deontology and amoralism. The results showed that the majority selected the deontological principle. Additionally, there was a considerable amount of fatalistic and virtue ethical justifications. Utilitarianism and psychopathy had a significant positive correlation. In Study 2 (n = 246), we replicated Study 1 and showed a significant relation between ACS and moral minimalism (the view that the sacrificial act is permissible but not necessary). In Study 3, the results showed that the utilitarian option in the sacrificial dilemmas was positively correlated with both real-life utilitarianism and psychopathy, but the latter two variables were not correlated with each other. All in all, the results suggest that some people choose the utilitarian option in moral dilemmas from psychopathic tendencies (as Kahane argued), while others due to real-life utilitarian reasons (as Greene argued). The findings also indicate that virtue ethical and fatalistic justifications cannot be ignored in understanding lay people's moral judgments

Neobisium yozgati n. sp., and N. anaisae n. sp. (Neobisiidae, Pseudoscorpiones), from Turkey and Macedonia (FYROM), respectively

Two new species of endemic and relict cave-dwellers of genus Neobisium Chamberlin, have been described from Turkey and Macedonia (FYROM), respectively. From its phenetically close congener, N. granulatum Beier, N. yozgati n. sp. (from Yozgat, Turkey) is distinguished in many important respects. In addition, N. anaisae n. sp. (from a cave in Krapa, FYROM) differs from its closest forms (N. korabense Ćurčić, N. ohridanum Hadži, and N. vladimirpantici Ćurčić) by many morphological characters and form of different body parts. Both species are illustrated, diagnosed, and thoroughly described. They both represent endemic and relict forms

Collective Excitations of (154)Sm nucleus at FEL{gamma}+LHC Collider

The production of collective excitations of the (154)Sm at FEL{gamma}+LHC collider is investigated. We show that this machine will be a powerful tool for investigation of high energy level excitations.Comment: 6 pages, 1 figure, 4 table

Young Double Slit Interference Effects at Quantum Level

The currently accepted model for quantum interference resulting from the emission of electron waves from two scattering centers induced by either light or charged particle impact is analogous to Young\u27s emission of two light waves from two slits. In this work we show that this simple classical wave model is incomplete and that there is a more complicated quantum interference pattern for low energy ionization caused by electron impact

Polynomial Solution of Non-Central Potentials

We show that the exact energy eigenvalues and eigenfunctions of the Schrodinger equation for charged particles moving in certain class of non-central potentials can be easily calculated analytically in a simple and elegant manner by using Nikiforov and Uvarov (NU) method. We discuss the generalized Coulomb and harmonic oscillator systems. We study the Hartmann Coulomb and the ring-shaped and compound Coulomb plus Aharanov-Bohm potentials as special cases. The results are in exact agreement with other methods.Comment: 18 page

Hysteretic response characteristics and dynamic phase transition via site dilution in the kinetic Ising model

The decay of the hysteresis loop area of the system, which is obeying a site diluted kinetic Ising model, is considered by the disorder parameter using the effective field theory analysis. The exhibition focuses on the understanding of external field frequency, amplitude and the site concentration dependency of the hysteresis loop area for several powerful treatments. Important characteristics of the hysteretic response, such as frequency dispersion, effect of domain nucleation phenomenon on the dynamic process etc. has been introduced together with well known other characteristics. An attempt has been made to explain the relations between the competing time scales (intrinsic microscopic relaxation time of the system and the time period of the external oscillatory field) and the shape of the response. As a result of the detailed investigations, existence of essentially three, particularly four types of dispersion curves have been propounded.Comment: 16 pages, 8 figure

Perspective of turkish medicine students on cancer, cancer treatments, palliative care, and oncologists (ares study): A study of the palliative care working committee of the turkish oncology group (TOG)

Cancer is one of the most common causes of death all over the World (Rahib et al. in Cancer Res 74(11):2913–2921, 2014; Silbermann et al. in Ann Oncol 23(Suppl 3):iii15–iii28, 2012). It is crucial to diagnose this disease early by effective screening methods and also it is very important to acknowledge the community on various aspects of this disease such as the treatment methods and palliative care. Not only the oncologists but every medical doctor should be educated well in dealing with cancer patients. Previous studies suggested various opinions on the level of oncology education in medical schools (Pavlidis et al. in Ann Oncol 16(5):840–841, 2005). In this study, the perspectives of medical students on cancer, its treatment, palliative care, and the oncologists were analyzed in relation to their educational status. A multicenter survey analysis was performed on a total of 4224 medical school students that accepted to enter this study in Turkey. After the questions about the demographical characteristics of the students, their perspectives on the definition, diagnosis, screening, and treatment methods of cancer and their way of understanding metastatic disease as well as palliative care were analyzed. The questionnaire includes questions with answers and a scoring system of Likert type 5 (absolutely disagree = 1, completely agree = 5). In the last part of the questionnaire, there were some words to detect what the words “cancer” and “oncologist” meant for the students. The participant students were analyzed in two study groups; “group 1” (n = 1.255) were phases I and II students that had never attended an oncology lesson, and “group 2” (n = 2.969) were phases III to VI students that had attended oncology lessons in the medical school. SPSS v17 was used for the database and statistical analyses. A value of p < 0.05 was noted as statistically significant. Group 1 defined cancer as a contagious disease (p = 0.00025), they believed that early diagnosis was never possible (p = 0.042), all people with a diagnosis of cancer would certainly die (p = 0.044), and chemotherapy was not successful in a metastatic disease (p = 0.003) as compared to group 2. The rate of the students that believed gastric cancer screening was a part of the national screening policy was significantly more in group 1 than in group 2 (p = 0.00014). Group 2 had a higher anxiety level for themselves or their family members to become a cancer patient. Most of the students in both groups defined medical oncologists as warriors (57% in group 1 and 40% in group 2; p = 0.097), and cancer was reminding them of “death” (54% in group 1 and 48% in group 2; p = 0.102). This study suggested that oncology education was useful for the students’ understanding of cancer and related issues; however, the level of oncology education should be improved in medical schools in Turkey. This would be helpful for medical doctors to cope with many aspects of cancer as a major health care problem in this country. © 2018, American Association for Cancer Education

Any l-state improved quasi-exact analytical solutions of the spatially dependent mass Klein-Gordon equation for the scalar and vector Hulthen potentials

We present a new approximation scheme for the centrifugal term to obtain a quasi-exact analytical bound state solutions within the framework of the position-dependent effective mass radial Klein-Gordon equation with the scalar and vector Hulth\'{e}n potentials in any arbitrary $D$ dimension and orbital angular momentum quantum numbers $l.$ The Nikiforov-Uvarov (NU) method is used in the calculations. The relativistic real energy levels and corresponding eigenfunctions for the bound states with different screening parameters have been given in a closed form. It is found that the solutions in the case of constant mass and in the case of s-wave ($l=0$) are identical with the ones obtained in literature.Comment: 25 pages, 1 figur
