K (892)± Resonance Production in Pb-Pb Collisions at √sNN=5.02 TeV
No full textThe first measurement of the e(+) e(-) pair production at midrapidity and low invariant mass in central Pb-Pb collisions at root sNN = 5.02 TeV at the Large Hadron Collider is presented. The yield of e(+)e(-) pairs is compared with a cocktail of expected hadronic decay contributions in the invariant mass (m(ee)) and pair transverse momentum (p(T,ee)) ranges m(ee) < 3.5 GeV/c(2) and p(T, ee) < 8 GeV/c. For 0.18 < m(ee) < 0.5 GeV/c(2) the ratio of data to the cocktail of hadronic contributions amounts to 1.40 +/- 0.11 (stat.) +/- 0.23 (syst.) +/- 0.16 (cocktail) and 1.42 +/- 0.11 (stat.) +/- 0.23 (syst.)(+0.24) (-0.29) (cocktail), including or not including medium effects in the estimation of the heavy-flavor background, respectively. It is consistent with predictions from two different models for an additional contribution of thermal e(+)e(-) pairs from the hadronic and partonic phases. In the intermediate-mass range (1.2 < mee < 2.6 GeV/c(2)), the pair transverse impact parameter of the e(+)e(-) pairs (DCA(ee), where DCA denotes distance of closest approach) is used for the first time in Pb-Pb collisions to separate displaced dielectrons from heavy-flavor hadron decays from a possible (thermal) contribution produced at the interaction point. The data are consistent with a suppression of e(+)e(-) pairs from cc and an additional prompt component. Finally, the first direct-photon measurement in the 10% most central Pb-Pb collisions at root sNN = 5.02 TeV is reported via the study of virtual direct photons in the transverse momentum range 1 < pT < 5 GeV/c. A model including prompt photons, as well as photons from the preequilibrium and fluid-dynamic phases, can reproduce the result, while being at the upper edge of the data uncertainties
Study of Flavor Dependence of the Baryon-to-Meson Ratio in Proton-Proton Collisions at √s=13 TeV
No full textAim: This study aimed to examine the relationship between ethical sensitivity and perceived clinical decision-making competence among nursing students. Background: Demonstrating ethical sensitivity in the perceived clinical decision-making competence is important for nursing students. During the pre-graduation period, students are expected to develop competence in making decisions based on ethical principles in clinical practice. Design: This study employed a descriptive and correlational design. Methods: Data were collected using self-reported online questionnaire. The study included 256 nursing students. Data were collected using the Sociodemographic Questionnaire, the Ethical Sensitivity Scale Adapted for Nursing Students, and the Clinical Decision-Making in Nursing Scale. Results: The mean total score for ethical sensitivity was 147.30 +/- 15.34 (scale range: 30-210) and the mean total score for perceived clinical decision-making competence was 134.06 +/- 29.44 (scale range: 40-200). A moderate positive correlation was found between ethical sensitivity and perceived clinical decision-making competence among nursing students (r = 0.399, p < .001). Furthermore, simple linear regression analysis revealed that students' level of ethical sensitivity significantly predicted their perceived clinical decision-making competence (F = 15.860, p < .001). Conclusions: Nursing students' ethical sensitivity and perceived clinical decision-making competence scores were above the midpoints of their respective scales, suggesting a relatively high level of ethical sensitivity and moderate-to-high perceived clinical decision-making competence. These findings indicate that higher ethical sensitivity positively influences nursing students' perceived clinical decision-making competence
Dielectron Production in Central Pb-Pb Collisions at √sNN=5.02 TeV
No full textThe first measurement of the e+e− pair production at midrapidity and low invariant mass in central Pb-Pb collisions at √sNN = 5.02 TeV at the Large Hadron Collider is presented. The yield of e+e− pairs is compared with a cocktail of expected hadronic decay contributions in the invariant mass (mee) and pair transverse momentum (pT,ee) ranges mee T,ee ee −0.29 (cocktail), including or not including medium effects in the estimation of the heavy-flavor background, respectively. It is consistent with predictions from two different models for an additional contribution of thermal e+e− pairs from the hadronic and partonic phases. In the intermediate-mass range (1.2 ee ee, where “DCA” denotes “distance of closest approach”) is used for the first time in Pb-Pb collisions to separate displaced dielectrons from heavy-flavor hadron decays from a possible (thermal) contribution produced at the interaction point. The data are consistent with a suppression of e+e− pairs from cc and an additional prompt component. Finally, the first direct-photon measurement in the 10% most central Pb-Pb collisions at √sNN = 5.02 TeV is reported via the study of virtual direct photons in the transverse momentum range 1 T < 5 GeV/c.

Measurement of f1(1285) Production in pp Collisions at s=13 TeV
No full textThis study presents the first measurement of the f1(1285) resonance using the ALICE detector in inelastic proton–proton collisions at a center-of-mass energy of 13 TeV. The resonance is reconstructed at midrapidity (|y|1(1285)→KS0K±π∓. Key measurements include the determination of its mass, transverse-momentum integrated yield, and average transverse momentum. Additionally, the ratio of the transverse-momentum integrated yield of f1(1285) to pion is compared with calculations from the canonical statistical hadronization model. The model calculation, assuming a zero total strangeness content for f1(1285), reproduces the data within 1σ deviation, shedding light on the quark composition of f1(1285). © 2025 CERN for the benefit of the ALICE Collaboratio

Association Between PTEN Status and Ovarian Cancer Prognosis: A Systematic Review and Meta-Analysis
No full textBackground: Phosphatase and TENsin homolog (PTEN), a tumor suppressor, is a critical factor in regulating the phosphoinositide 3-kinase (PI3K) pathway to prevent excessive cell growth. Absence or alteration of PTEN expression is associated with poor prognosis of ovarian carcinomas. This systematic review and meta-analysis aim to investigate the relationship between PTEN status and ovarian cancer prognosis. Method: A systematic literature search was conducted up to October 8, 2023, to find relevant articles from PubMed, Scopus, Web of Science, and Cochrane Library. Eligible studies were included. The meta-analysis was performed after data extraction and quality assessment. Result: Seventeen studies with a total of 2395 women with ovarian cancer were included. The hazard ratio (HR) was defined as a measure of the predictive value of the risk of death for patients with PTEN-positive tumors. Analysis was performed based on overall survival (OS) and progression-free survival (PFS). A positive correlation was observed in both cases (OS: HR = 0.75, 95% CI = [0.54, 1.05]; PFS: HR = 0.87, 95% CI = [0.59, 1.28]); however, it was not significant. After adjusting the variables, this positive relationship remained insignificant (OS: HR = 0.89, 95% CI = [0.57, 1.41]; PFS: HR = 0.91, 95% CI = [0.41, 2.00]). Egger’s test, Begg’s test, and funnel plot showed no publication bias. Conclusion: This systematic review and meta-analysis suggests a potential association between PTEN status and ovarian cancer prognosis; however, the findings were not statistically significant and should be interpreted with caution. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2025
Multi-Capacitated Waste Collection Routing Problem With Container Fill Levels
No full textEfficient and sustainable waste collection is a critical challenge in modern urban management. This study proposes a new Mixed Integer Linear Programming (MILP) model to address the Waste Collection Routing Problem by incorporating both the weight and volume capacities of vehicles along with container fill levels. The model optimizes vehicle routes by dynamically excluding containers that do not meet a predefined occupancy threshold, thereby reducing unnecessary trips and operational costs. The proposed model is implemented using the GUROBI solver in Python and tested on multiple hypothetical scenarios with varying customer and vehicle configurations. Results show that the total collection cost (measured as travel distance) increased from 285 units for 10 containers with 2 vehicles to 511 units for 30 containers with 4 vehicles, revealing a clear relationship between container quantity and route complexity. These findings demonstrate the model's effectiveness in minimizing total distance while adapting to real-time container conditions, contributing to smart and responsive waste management strategies. © 2025 IEEE
Rapid Detection of Pathogens and Resistance Genes Grown in Blood Cultures With Two Multiplex Tandem Real-Time PCR Kits
No full textObjective: In this study, two multiplex tandem real-time PCR kits were used to rapidly diagnose common Gram-positive cocci and Gram-negative bacilli, detect their commonly seen antibiotic resistance genes, and evaluate the two kits’ performance. Materials and Methods: Gram-positive 12 (GP-12) kit (AusDiagnostics, Australia) and Gram-negative 12 (GN-12) kit (AusDiagnostics, Australia) were used in the study. Seventy-eight Gram-negative bacilli and 54 Gram-positive cocci grown in blood culture vials were applied to GN-12 and GP-12 panels. At the same time, the passages of the samples were made and incubated. After that, identification and antibiograms were made in the Phoenix™ automated system (Becton, Dickinson and Company, USA) and VITEK 2 Compact automated system (bioMérieux, France). Results: Twenty-one Staphylococcus aureus, twelve coagulase-negative staphylococci (CoNS), two Streptococcus pneumoniae, two Enterococcus faecium, and three Enterococcus faecalis were found to match the results from the automated GP-12 Kit. Pathogens present in the panel were successfully identified using the GN-12 kit. Both panels were found to be more effective in diagnosing polymicrobial infections. Conclusion: These evaluated kits were rapid (approximately three hours) and valuable in identifying common sepsis pathogens and resistance genes. Thus, these tests can easily be used in the diagnosis of sepsis. © 2025, DOC Design and Informatics Co. Ltd.. All rights reserved

Pupillometri Kullanılarak Bilinçli ve Bilinçdışı Tüketici Tepkilerinin Pazarlama Açısından Değerlendirilmesi: Sistematik Bir Derleme
No full textNöropazarlama araştırmaları, geleneksel öz-bildirim ve davranışsal ölçümlerin sınırlılıklarını aşmak amacıyla giderek daha fazla bilinçdışı tüketici süreçlerini yakalayabilen fizyolojik teknikleri içermeye yönelmiştir. Bu teknikler arasında, göz bebeği büyüklüğü (pupil dilation), duygusal uyarılma, bilişsel çaba ve motivasyonel katılımı değerlendirmek için değerli ancak yeterince kullanılmayan bir ölçüt olarak öne çıkmaktadır. Kuramsal vaatlerine rağmen, göz bebeği büyüklüğü, ana akım tüketici davranışı araştırmalarında halen odaklanma temelli göz takibi metriklerinin gölgesinde kalmaktadır. Belirtilen önceliklerle bu çalışma, pazarlama ve tüketici davranışı bağlamlarında göz bebeği büyüklüğü kullanan 30 ampirik çalışmayı sistematik olarak incelemektedir. TCCM çerçevesi kullanılarak, göz bebeği temelli metriklerin nasıl kuramsallaştırıldığı, uygulandığı ve yorumlandığı çeşitli pazarlama perspektiflerinden analiz edilmektedir. Bulgular, göz bebeği büyüklüğünün ağırlıklı olarak görsel dikkat, duygusal uyarılma, bilişsel yük ve tercih oluşumuyla ilişkili olduğunu ortaya koymakta; tüketicilerin bilinçdışı tepkilerine dair sözel olmayan, gerçek zamanlı bir pencere sunduğunu göstermektedir. Ancak literatürde, ışık hassasiyeti, duygusal değer belirsizliği ve standartlaşma eksikliği gibi metodolojik sınırlılıklar devam etmektedir. Özetle, bu derleme, göz bebeği büyümesinin tüketici sinirbiliminde tanılayıcı bir araç olarak henüz tam olarak değerlendirilmemiş potansiyeline dikkat çekmekte ve gelecekteki araştırmalar için daha fazla çok modlu entegrasyon, ekolojik geçerlik ve kültürler arası incelemenin önemini ortaya koymaktadır. Odaklanma temelli metriklerin ötesine geçilmesinin, araştırmacılar ve uygulayıcılar için tüketici davranışının gizli bilişsel ve duygusal etkenlerini daha yakından inceleyebilmesine olanak tanıyacağı düşünülmektedir.Neuromarketing research has increasingly sought to transcend the limitations of traditional self-report and behavioral measures by incorporating physiological techniques that capture nonconscious consumer processes. Among these, pupil dilation has emerged as a valuable yet underutilized metric for assessing emotional arousal, cognitive effort, and motivational engagement. Despite its theoretical promise, pupil dilation remains secondary to fixation-based eye-tracking metrics in mainstream consumer behavior research. This study systematically reviews 30 empirical studies employing pupil dilation within marketing and consumer behavior contexts. Using the TCCM framework, we analyze how pupil-based metrics have been theorized, applied, and interpreted across diverse marketing settings. A bibliometric analysis complements the review, mapping the intellectual structure and thematic evolution of pupillometric consumer research. Findings reveal that pupil dilation is predominantly associated with visual attention, emotional arousal, cognitive load, and preference formation, offering a nonverbal, real-time window into consumers’ subconscious responses. However, methodological limitations such as luminance sensitivity, emotional valence ambiguity, and lack of standardization persist across the literature. This review highlights the untapped potential of pupil dilation as a diagnostic tool in consumer neuroscience and calls for greater multimodal integration, ecological validity, cross-cultural exploration, and methodological rigor in future research. By moving beyond fixation-based metrics, scholars and practitioners can better capture the hidden cognitive and affective drivers of consumer behavior
