Öğe Continuous Intuitionistic Fuzzy AHP & CODAS Methodology for Automation Degree Selection(Old City Publishing Inc, 2024) Alkan, Nursah; Otay, Irem; Gul, Alize Yaprak; Demir, Zeynep Burcu Kizilkan; Dogan, OnurThe automotive industry's evolution thrives on technological innovation, prioritizing efficiency, safety, and sustainability. Recent improvements in autonomous driving and IoT integration have revolutionized vehicle design, safety, and maintenance with different automation degrees from partial human control to full automation. Selecting these automation degrees involves complicated Multi-Criteria Decision-Making (MCDM) encompassing technical feasibility, societal impact, and regulatory compliance. Utilizing Analytic Hierarchy Process (AHP) and Combinative Distance-Based Assessment (CODAS) offers a structured framework to navigate these complexities. AHP establishes criteria importance, while CODAS handles uncertainties, enabling informed decisions balancing technology with ethical, societal, and regulatory considerations. Fuzzy extensions further refine these methodologies, empowering the industry to adeptly address subjective perceptions and ambiguous data, enhancing the decision-making framework for automotive technology evolution. This paper navigates the intricate landscape of automation degree selection within the automotive industry evolution, employing a structured approach merging fuzzy AHP and fuzzy CODAS methods by utilizing Continuous Intuitionistic Fuzzy Set (CINFUS). This approach not only brings a new perspective to autonomous vehicles but also highlights the importance of choosing the right automation degree. Moreover, a sensitivity analysis involved adjusting the weights assigned to different criteria within the Continuous Intuitionistic Fuzzy (CINFU) AHP framework. By systematically altering these weights and observing their impact on the final automation degree selection, decision-makers can understand the sensitivity of the chosen automation degree to changes in priority among criteria.Öğe Evaluation of Hand Morphometry in Healthy Young Individuals from Different Countries(Soc Chilena Anatomia, 2024) Sahin, Necati Emre; Bakici, Rukiye Sumeyye; Toy, Seyma; Oner, ZulalThis study aims to examine the hand morphometry of healthy young individuals from different countries and investigate the differences between countries in typing of hand based on the morphometric values obtained. In the study, 16 different parameters, including two surface areas and 14 lengths, were measured from the right hand of 579 volunteers (250 females, 329 males) from 7 different countries (Turkey, Chad, Morocco, Gabon, Kazakhstan, Senegal and Syria). Factor analysis was performed on the parameters, cluster analysis was performed according to the factor score obtained, and the hand types in the study were determined. As a result of the study, four different hand types were defined, and the distribution of these types according to countries was analyzed. All parameters showed significant differences between countries in both genders (p<0.05). According to the results of the study, there was a difference between male and female hand types between countries. In females, the type 1 hand type was found only in Gabon, the type 2 hand type was found only in Senegal, the type 3 hand type was found in Turkey, Morocco and Kazakhstan, while the type 4 hand type was significantly distributed in Senegal and Gabon (X-2 =104.62; df=18, p<0.05). In males, type 1 hand type was found in Turkey, type 2 hand type in Senegal and Gabon, type 3 hand type in Turkey, while type 4 hand type was significantly distributed in Morocco and Kazakhstan (X-2 =76.964; df=18, p<0.05).Öğe Determining the Relationship Between Death Anxiety and Decision on Organ Donation(Asoc Regional Dialisis Trasplantes Renales, 2024) Koze, Burcak Sahin; Alcan, Aliye OkgunIntroduction: Individuals' thoughts and concerns about death can affect the decision-making process for organ donation. Objective: This descriptive study aims to determine the relationship between death anxiety and decision-making for organ donation. Material and Methods: The population of the study consisted of individuals aged 18 and over from Turkish society. The study sample consisted of 232 participants aged 18 and over who could actively use the Internet and voluntarily agreed to participate. The study data were collected using the Thorson-Powell Death Anxiety Scale and the Organ Donation Decision-Making Questionnaire via the Internet between February and April 2021. Results: In this study, 84.5% of the participants were women; the average age was 30.14 +/- 10.0. Participants' Thorson-Powell Death Anxiety Scale total score average was 43.95 +/- 16.93. The Organ Donation Decision Making Questionnaire advantage score average was 24.57 +/- 5.13, disadvantage mean score was 16.31 +/- 5.77, and decision mean score was 1.76 +/- 0.92. It was observed that there was a positive and weak correlation (r = .20, p = .002) between the Thorson-Powell Death Anxiety Scale total scores of the participants and the decision score averages of the Organ Donation Decision Questionnaire. Conclusions: It was observed that the organ donation decisions of the participants with death anxiety were positive. It is recommended to carry out more studies and organize training programs to determine the factors that will affect the organ donation decision of individuals. Conducting qualitative studies examining beliefs about death and cultural factors in deciding on organ donation is recommended.Öğe Sex Prediction of Hyoid Bone from Computed Tomography Images Using the DenseNet121 Deep Learning Model(Soc Chilena Anatomia, 2024) Bakici, Rukiye Sumeyye; Cakmak, Muhammet; Oner, Zulal; Oner, SerkanThe study aims to demonstrate the success of deep learning methods in sex prediction using hyoid bone. The images of people aged 15-94 years who underwent neck Computed Tomography (CT) were retrospectively scanned in the study. The neck CT images of the individuals were cleaned using the RadiAnt DICOM Viewer (version 2023.1) program, leaving only the hyoid bone. A total of 7 images in the anterior, posterior, superior, inferior, right, left, and right-anterior-upward directions were obtained from a patient's cut hyoid bone image. 2170 images were obtained from 310 hyoid bones of males, and 1820 images from 260 hyoid bones of females. 3990 images were completed to 5000 images by data enrichment. The dataset was divided into 80 % for training, 10 % for testing, and another 10 % for validation. It was compared with deep learning models DenseNet121, ResNet152, and VGG19. An accuracy rate of 87 % was achieved in the ResNet152 model and 80.2 % in the VGG19 model. The highest rate among the classified models was 89 % in the DenseNet121 model. This model had a specificity of 0.87, a sensitivity of 0.90, an F1 score of 0.89 in women, a specificity of 0.90, a sensitivity of 0.87, and an F1 score of 0.88 in men. It was observed that sex could be predicted from the hyoid bone using deep learning methods DenseNet121, ResNet152, and VGG19. Thus, a method that had not been tried on this bone before was used. This study also brings us one step closer to strengthening and perfecting the use of technologies, which will reduce the subjectivity of the methods and support the expert in the decision-making process of sex prediction.Öğe Medieval European Witchcraft and the Perception of Women in Select Philippine Short Stories(Int Islamic Univ Malaysia, Dept English Language & Literature, 2024) Magan, Rhodora; Gul, OzlemThis study addresses the persistent narrative of witchcraft-related violence in the contemporary era by delving into its historical root - the medieval practice of witch-hunts. It investigates gendered motifs linked to women accused of witchcraft and sorcery, using Morgan le Fay in Thomas Malory's Morte Darthur as a reference. By examining gender stereotypes, we aim to demonstrate how medieval European concepts of witchcraft and sorcery have become entrenched in modern perceptions of women. This investigation employs Philippine literary texts - The Witch by Edilberto Tiempo and May Day Eve by Nick Joaquin, characterising women exhibiting postcolonial dispositions. Our central hypothesis holds that these contemporary stories adapt the medieval classic. The findings point to the medieval traces in the characters of Minggay and Agueda, leading to their societal categorisation as metaphorical witches. Textual analysis exemplifies strategies such as un/belonging the self to demonstrate herstory, acknowledging one's beliefs to express innate tendencies, and challenging social structures to promote reclamation of oppressive structures. This study contributes to understanding the challenged mythical nature of women's identity in the modern era. Hence, the adaptive platform of medieval European influence lends support to stabilising women's positionality rather than their essentiality.Öğe Cultural Integration of First-Generation Immigrants: Evidence from European Union Countries(Digital Initiatives Univ Waterloo Lib, 2023) Giovanis, Eleftherios; Akdede, Sacit HadiIn this study, we aim to explore and compare the frequency of attendance and the reasons for nonattendance to cultural activities between natives and first-generation immigrants in thirteen European countries. The empirical analysis relies on data from the special module on cultural participation in the European Union-Income and Living Conditions Survey (EU-SILC) in 2015. We apply the Probit and multinomial Probit models. This study contributes to the literature by exploring the determinants of cultural participation and comparing the frequency of participation in cultural activities between natives and first-generation immigrants. Furthermore, the study explores the reasons for non-participation in cultural activities, highlighting potential differences between countries and between the European Union (EU) and non-EU migrants. The results highlight that social interactions depend on several factors related mainly to the country of destination and employment opportunities and individual factors related to the migrant, including demographic and economic characteristics and the length of residence in the host country. The findings show that the length of residence of immigrants in the host countries is positively correlated with a higher frequency of attendance, indicating that cultural participation can be, by its nature, a long-term process or experienced activity. The findings also show that in most cases, migrants do not attend the cultural activities we explore because of financial constraints and not due to lack of interest. Thus, this highlights that the economic integration of migrants could be the primary driver of cultural participation and integration.Öğe tVNS alters inflammatory response in adult VPA-induced mouse model of autism: evidence for sexual dimorphism(Wiley, 2025) Dagidir, Hale Gok; Bukan, Neslihan; Bahcelioglu, Meltem; Calikusu, Aysen; Alim, Ece; Dizakar, Saadet Ozen; Topa, ElifAutism is a neurodevelopmental disorder with limited treatment alternatives and which incidence is increasing. Some research suggests that vagus nerve simulation might lead to the reduction of certain symptom. Therefore, we aimed to examine the effect of bilateral transcutaneous auricular vagus nerve stimulation (tVNS) on the inflammatory response in an adult valproic acid (VPA) induced mouse (C57BL6) model of autism for the first time. The autism model was induced by oral VPA administration (600 mgkg(-1)) to C57BL/6 pregnant mice on E12.5 days. The study included three groups: the VPA Transcutaneous Auricular Stimulation Group (VPA + tVNS), the VPA Control Group (VPA + sham), and the Healthy Control Group (Control + sham). Each group included 16 mice (8 M/8 F). Our results show that serum IL-1 beta and IL-6 levels were significantly higher in male VPA-exposed mice than controls. However, IL-1 beta was significantly lower, and IL-6, TNF- alpha, and IL-22 were not different in female VPA-exposed mice compared to the control group. Brain NLRP3 levels were significantly higher in both sexes in the VPA autism model (P < 0.05). tVNS application increased brain NLRP3 levels in both sexes and reduced serum IL-1 beta levels in male mice. We conclude that cytokine dysregulation is associated with the VPA-induced adult autism model, and the inflammatory response is more pronounced in male mice. tVNS application altered the inflammatory response and increased brain NLPR3 levels in both sexes. Further studies are needed to understand the beneficial or detrimental role of the inflammatory response in autism and its sexual dimorphism.Öğe DIAGNOSTIC COMPARABILITY OF RATIO OF TISSUE DIELECTRIC CONSTANT (TDC) BETWEEN PATIENTS WITH LIPEDEMA AND THOSE WITH LOWER LIMB LYMPHEDEMA (LLL): A PROSPECTIVE OBSERVATIONAL STUDY(Lymphology, 2023) Tugral, A.; Bakar, Y.Lipedema is usually thought of as a dis-ease of women. Potentially diagnostic comparative data is needed between patients with lip-edema and those with lower limb lymphedema (LLL). Since there is no gold standard to diag-nose lipedema, some promising modalities such as Tissue Dielectric Constant (TDC) need to be investigated among patients with lipedema and lymphedema. This study was completed with a total of 26 patients (14 lipedema, 12 LLL). Local tissue water was assessed with Moisture MeterD compact (DelfinTech, Kuopio, Fin-land) according to the TDC method at 300 MHz within a 2.5 mm tissue penetration depth via the following reference points: Thigh, calf (20 cm upper and lower point of knee level, respectively), and malleoli (5 cm upper point of medial malleolus). Patients with LLL showed significantly higher TDC values and interlimb TDC ratios in all affected points and unaffect-ed malleolus points compared to patients with lipedema. No significant difference wasachieved between genders with LLL in all ref-erence points. The area under the curve (AUC) for thigh, calf, and malleolus reference points were found as 0.851 (95%CI .678-1.00), 0.801 (95% CI 0.612-0.989) and 0.786 (95%CI 0.596-0.976), respectively. Patients with LLL showed significantly higher TDC values compared to patients with lipedema, these differences should be carefully interpreted in patients with bilateral LLL and those with lipo-lymphedemaÖğe Letter to Correlation of immediate prevalence of cervical squamous cell precancers and cancers with HPV genotype and age in women with LSIL cytology(Wiley, 2024) Yavuz, Onur; Karaca, Ibrahim[No abstract available]Öğe Expression levels of tam receptors and ligands in the testes of rats exposed to short and middle-term 2100 MHz radiofrequency radiation(Wiley, 2024) Katirci, Ertan; Kirimlioglu, Esma; Oflamaz, Asli O.; Hidisoglu, Enis; Cernomorcenco, Alexandra; Yargicoglu, Piraye; Ozen, SukruWith advances in technology, the emission of radiofrequency radiation (RFR) into the environment, particularly from mobile devices, has become a growing concern. Tyro 3, Axl, and Mer (TAM) receptors and their ligands are essential for spermatogenesis and testosterone production. RFR has been shown to induce testicular cell apoptosis by causing inflammation and disrupting homeostasis. This study aimed to investigate the role of TAM receptors and ligands in the maintenance of homeostasis and elimination of apoptotic cells in the testes (weeks), short-term sham exposure (sham/1 week), and middle-term sham exposure (sham/10 weeks). Testicular morphology was assessed using hematoxylin-eosin staining, while immunohistochemical staining was performed to assess expression levels of TAM receptors and ligands in the testes of all groups. The results showed that testicular morphology was normal in the control, sham/1 week, and sham/10 weeks groups. However, abnormal processes of spermatogenesis and seminiferous tubule morphology were observed in RFR exposure groups. Cleaved Caspase 3 immunoreactivity showed statistically significant difference in 1 and 10 weeks exposure groups compared to control group. Moreover, there was no significant difference in the immunoreactivity of Tyro 3, Axl, Mer, Gas 6, and Pros 1 between groups. Moreover, Tyro 3 expression in Sertoli cells was statistically significantly increased in RFR exposure groups compared to the control. Taken together, the results suggest that RFR exposure negatively affects TAM signalling, preventing the clearance of apoptotic cells, and this process may lead to infection and inflammation. As a result, rat testicular morphology and function may be impaired. Exposure to radiofrequency radiation (RFR) disrupts normal seminiferous tubule morphology. RFR exposure in round spermatids may induce apoptosis independent of Tyro 3, Axl, and Mer (TAM) receptors. TAM receptors and ligands are expressed in rat testis.Öğe Characterization of PbMo0.3W0.7O4 Crystal: A Potential Material for Photocatalysis and Optoelectronic Applications(Wiley-V C H Verlag Gmbh, 2024) Isik, Mehmet; Gasanly, Nizami MamedPbMo0.3W0.7O4 semiconductor crystal, which contains the balanced ratios of Mo and W, is grown for the first time by Czochralski method.

CLV is a critical approach to managing and organizing a company's profitability. With the vast availability of consumer data, business analytics (BA) tools and approaches, alongside CLV models, have been applied to gain deeper insights into customer behaviors and decision-making processes. Despite the recognized importance of CLV, there is a noticeable gap in comprehensive analyses and reviews of BA techniques applied to CLV. This study aims to fill this gap by conducting a thorough survey of the state-of-the-art investigations on CLV models integrated with BA approaches, thereby contributing to a research agenda in this field. The review methodology consists of three main steps: identification of relevant studies, creating a coding plan, and ensuring coding reliability. First, relevant studies were identified using predefined keywords. Next, a coding plan-one of the study's significant contributions-was developed to evaluate these studies comprehensively. Finally, the coding plan's reliability was tested by three experts before being applied to the selected studies. Additionally, specific evaluation criteria in the coding plan were implemented to introduce new insights. This study presents exciting and valuable results from various perspectives, providing a crucial reference for academic researchers and marketing practitioners interested in the intersection of BA and CLV.Öğe Global prevalence and risk factors of obstetric violence: A systematic review and meta-analysis(Wiley, 2025) Hakimi, Sevil; Allahqoli, Leila; Alizadeh, Maryam; Ozdemir, Meryem; Soori, Hamid; Turfan, Esin Ceber; Sogukpinar, NerimanBackgroundObstetric violence (OBV), defined as mistreatment or abuse during childbirth, is a pervasive global issue, albeit with regional differences, affecting women's physical and emotional well-being.ObjectivesThe purpose of this systematic review and meta-analysis is to assess the prevalence of OBV to identify risk factors associated with OBV and to make suggestions for improving maternal healthcare practices and policies.Search StrategyIn a systematic review and meta-analysis, we searched four electronic databases for studies published over 10 years up to 31 January 2024: Medline (PubMed), Scopus, Embase, and Web of Science (WOS). The search was conducted among English language papers using a carefully curated set of keywords.Selection CriteriaWe conducted a comprehensive review, including all observational reporting data on the prevalence of and risk factors associated with OBV, irrespective of geographical location. The studies included in the review were required to be published in peer-reviewed. journals and available in the English language.Data Collection and AnalysisThe data of the studies were summarized in an Excel file (version 19) and analyzed using R (version 4.2.3). A meta-analysis was performed to evaluate the pooled prevalence of and identify risk factors associated with OBV.Main ResultsThe global prevalence of OBV estimated based on 25 studies, calculated with a random-effects model, was 59% (95% confidence interval [CI] 0.48-0.70; I2 = 99.5%). The most prevalent subdomain of OBV was non-consented care (37%; 95% CI 0.23-0.50; I2 = 99.7%). The following factors were found to be significantly associated with OBV: the presence of a midwife as skilled personnel beside the woman during childbirth (odds ratio [OR] [95% CI] = 0.4 [0.2-0.9]), which might reduce the likelihood of OBV; middle and high levels of income (OR [95% CI] = 0.5 [0.2-0.7]), which might also reduce the likelihood of OBV; and vaginal delivery (OR [95% CI] = 2.08 [1.1-3.08]), which is liable to increase the likelihood of OBV.ConclusionThis systematic review and meta-analysis highlights the considerable prevalence and multifaceted nature of OBV, underscoring the urgent need for interventions at multiple levels to address this pervasive issue and ensure respectful, safe, and dignified maternal healthcare for all women.Öğe Third-trimester fetal pancreas imaging in uncomplicated pregnancies and association with pregnancy outcomes(Wiley, 2024) Golbasi, Hakan; Bayraktar, Burak; Golbasi, Ceren; Omeroglu, Ibrahim; Atakul, Bahar Konuralp; Cakir, Zubeyde Emiralioglu; Toka, Ilknur GumusObjective: To examine third-trimester sonographic imaging of the fetal pancreas in uncomplicated pregnancies and its association with pregnancy outcomes. Methods: This was a prospective cohort study including 274 pregnant women. Uncomplicated pregnancies in the third trimester (28-40 weeks) were included in the study. Maternal chronic disease, pregnancy-related disorders such as hypertension, diabetes, cholestasis, smoking, and fetal abnormalities were determined as exclusion criteria. Sonographic fetal pancreatic measurement and echogenicity were evaluated in all participants. For intra-observer reliability, each participant's fetal pancreatic circumference was measured two times. The echogenicity of the pancreas was compared with the liver and ribs and classified as grade 1, 2, and 3. The pregnancy outcomes of all participants were obtained from the hospital digital registration system. Results: The average fetal pancreatic circumference in the third trimester was 70.7 +/- 0.6 mm (median, 70 [44-100.7]), with high intra-observer agreement (ICC 0.996 [0.995; 0.997]). A significant positive correlation was found between pancreatic circumference, body mass index (BMI), gestational age, and birth weight. Pancreatic measurements were significantly higher in composite adverse outcomes cases that included at least one of respiratory distress syndrome, hyperbilirubinemia, neonatal pneumonia, infection, and sepsis (p < 0.001). No relationship was found between pancreatic echogenicity and perinatal outcomes. Conclusion: Fetal pancreas size was positively correlated with gestational age, BMI, and birth weight, and increased fetal pancreas size was associated with composite adverse neonatal outcomes.Öğe AGK2, a SIRT2 inhibitor, ameliorates D-galactose-induced liver fibrosis by inhibiting fibrogenic factors(Wiley, 2024) Bahar, Asli Nur; Keskin-Aktan, Arzu; Akarca-Dizakar, Saadet Ozen; Sonugur, Gizem; Akbulut, Kazime GoncaIn our study, we aimed to investigate the effect of SIRT2 inhibition on function, fibrosis and inflammation in liver fibrosis induced by D-Galactose (D-Gal) administration. A total of 32 3-month-old Sprague Dawley rats were used in the study. Rats were divided into 4 groups as Control, d-Gal, Solvent+d-Gal, d-Gal+AGK2+Solvent. d-Gal (150 mg/kg/day), AGK-2 (10 mu M/bw) as a specific SIRT2 inhibitor, 4%DMSO + PBS as a solvent was applied to the experimental groups and physiological saline was applied to the control group for 10 weeks. All applications were performed subcutaneously. Histological fibrotic changes were studied in the liver tissues by Masson's trichrome staining, hematoxylin and eosin staining and immunohistochemistry and the levels of selected factors were determined by quantitative reverse transcription-polymerase chain reaction, western blot analysis, and immunohistochemical analysis. Biochemical parameters and Paraoxonase levels were determined in the plasma. d-Galactose administration increased AST, AST-ALT Ratio, APRI, SIRT2 protein expression, IL1 beta, TGF beta, beta-catenin, Type I collagen, Type III collagen and alpha-SMA, collagen fiber density and histopathological score. ALT and lipid panels were not changed and paraxonase plasma level was shown to decrease. These effects were largely blocked by the SIRT2 inhibitor AGK2. These findings suggest that SIRT2 inhibition attenuates d-Gal-induced liver injury and that this protection may be due to its antifibrotic and anti-inflammatory activities.Öğe Use of Cervical Fascia to Prevent Pharyngocutaneus Fistula After Total Laryngectomy(Wiley, 2024) Zorlu, Mehmet Ekrem; Kertmen, Canberk; Aysel, Abdulhalim; Yilmaz, Fatih; Dalgic, Abdullah; Muderris, TogayObjective: This study aimed to compare the pharyngocutaneous fistula (PCF) between patients who underwent reconstruction using cervical fascia after total laryngectomy and those who did not and to investigate the factors affecting PCF rates. Methods: We retrospectively compared 22 patients operated between February 2021 and March 2023 who received cervical fascia flap as the study group and 21 patients operated between January 2018 and March 2023 who did not receive fascia flap as the control group. The study included patients who underwent total laryngectomy for Stage 3 and 4 squamous cell laryngeal cancer. Results: We included 43 patients, with 22 (51.2%) and 21 patients (48.8%) in the study and control groups, respectively. The age and sex were not different between the two groups (p=0.471, p=0.176, respectively). The distribution of patients as per sex, smoking, alcohol use, chronic obstructive pulmonary disease, diabetes mellitus, coronary artery disease, and multiple comorbidities was similar in both groups (p>0.05). PCF was observed in one patient (4.5%) and seven patients (33.3%) in the study and control groups, respectively. The PCF rate was significantly lower in the study group (p=0.021). When the relationship between flap use and risk factors was compared by correlation analysis, a moderate negative relationship was found between flap use and PCF (p=0.015, r=-0.370). Conclusion: The use of a cervical fascia flap is effective in reducing fistula rates after total laryngectomy. Its main advantages include being technically simpler than alternative techniques, locally available, cost-effective.Öğe Time Series Clustering of Sea Surface Temperature in the Mediterranean and Black Sea Marine System(Wiley, 2024) Tagil, Sermin; Danacioglu, Sevki; Yurtseven, NamiSea surface temperature (SST) is a significant climatic variable that affects the climate of the Earth. Monitoring a location's SST pattern is useful for several research areas, including weather forecasting and climate change. In this study, the emerging hot spot and cold spot patterns of SST in the Mediterranean and Black Sea Marine System (MBMS) were examined, the spatial distribution characteristics and temporal changes of SST in the sub-basins were analysed, and future predictions were made. A distinctive aspect of the research lies in the introduction of novel techniques, specifically the application of space time cube and evolving hot spot analysis, for visualising and evaluating SST in the MBMS. This approach sets the study apart by pioneering the utilisation of these methods in this particular context. In the examined region, SST demonstrates a decreasing trend from east to west and from south to north. The forecast suggests that this spatial distribution pattern will persist in 2033, further accentuated by the intensification of the warming effect. Nine different time series clusters are defined within this distribution pattern. Although it changes seasonally, the prevailing statistically significant hot spots in the study area are primarily characterised by new hot spots, intensifying hot spots, sporadic hot spots and oscillating hot spots. The trends of hot and cold spot clusters, along with SST values, were assessed for all sub-basins in the MBMS. Conversely, the observed clustering category among statistically significant cold spots is identified as persistent cold spots, diminishing cold spots, sporadic cold spots, oscillating cold spots and historical cold spots. The spatiotemporal analysis in this research has provided notable insights, offering a spatial context to the previously explored temporal trends of SST in the MBMS.Öğe Measurement of the τ lepton polarization in Z boson decays in proton-proton collisions at √s=13 TeV(Springer, 2024) Hayrapetyan, A.; Tumasyan, A.; Adam, W.; Andrejkovic, J. W.; Bergauer, T.; Chatterjee, S.; Damanakis, K.The polarization of tau leptons is measured using leptonic and hadronic tau lepton decays in Z -> tau(+)tau(-) events in proton-proton collisions at root s = 13 TeV recorded by CMS at the CERN LHC with an integrated luminosity of 36.3 fb(-1). The measured tau(-) lepton polarization at the Z boson mass pole is P-tau(Z) = -0.144 +/- 0.006 (stat) +/- 0.014 (syst) = -0.144 +/- 0.015, in good agreement with the measurement of the tau lepton asymmetry parameter of A(tau) = 0.1439 +/- 0.0043 = -P-tau(Z) at LEP. The tau lepton polarization depends on the ratio of the vector to axial-vector couplings of the tau leptons in the neutral current expression, and thus on the effective weak mixing angle sin(2)theta(eff)(W), independently of the Z boson production mechanism. The obtained value sin(2)theta(eff)(W) = 0.2319 +/- 0.0008(stat) +/- 0.0018(syst) = 0.2319 +/- 0.0019 is in good agreement with measurements at e(+)e(-) colliders.Öğe Enhancing Hospital Services: Utilizing Chatbot Technology for Patient Inquiries(Springer International Publishing Ag, 2024) Dogan, Onur; Gurcan, Omer FarukThis paper investigates the implementation and impact of a chatbot system within a hospital environment to address patient inquiries. The study focuses on the development and deployment of a non-medical knowledge-based chatbot designed to respond to a spectrum of queries typically handled by hospital call centers. The chatbot system's primary objective is to provide prompt, accurate, and accessible information to patients, streamlining their interaction process and reducing waiting times. The research explores the technical architecture and functionality of the chatbot, emphasizing its intuitive interface and ability to cater to a diverse range of patient queries. Utilizing a chatbot, data collection includes quantitative analysis of patient inquiries' pre- and post-chatbot implementation, alongside qualitative insights derived from patient feedback. The developed chatbot based on embedding techniques and a pre-trained Large Language Model gives an accuracy of 89%. Preliminary findings emphasized the potential for intelligent virtual assistants to transform patient interactions, enhance information accessibility, and ultimately contribute to the overall improvement of hospital services.Öğe Measurement of the Higgs boson production via vector boson fusion and its decay into bottom quarks in proton-proton collisions at √s=13 TeV(Springer, 2024) Hayrapetyan, A.; Tumasyan, A.; Adam, W.; Andrejkovic, J. W.; Bergauer, T.; Chatterjee, S.; Damanakis, K.A measurement of the Higgs boson (H) production via vector boson fusion (VBF) and its decay into a bottom quark-antiquark pair (b (b) over bar) is presented using proton-proton collision data recorded by the CMS experiment at root s = 13TeV and corresponding to an integrated luminosity of 90.8 fb(-1). Treating the gluon-gluon fusion process as a background and constraining its rate to the value expected in the standard model (SM) within uncertainties, the signal strength of the VBF process, defined as the ratio of the observed signal rate to that predicted by the SM, is measured to be mu(qqH)(Hb (b) over bar) = 1.01(-0.46)(+0.55). The VBF signal is observed with a significance of 2.4 standard deviations relative to the background prediction, while the expected significance is 2.7 standard deviations. Considering inclusive Higgs boson production and decay into bottom quarks, the signal strength is measured to be mu(incl.)(Hb (b) over bar) = 0.99(-0.41)(+0.48), corresponding to an observed (expected) significance of 2.6 (2.9) standard deviations.
