Space to Place, Housing to Home: A Systematic Review of Sense of Place in Housing Studies
No full textThis study conducts a systematic qualitative review of empirical research on sense of place within housing contexts, employing the tripartite model of place identity, place attachment, and place dependence. The study employs an expanded model that captures the internal complexity of each indicator by integrating its cognitive, affective, and conative components, which represent the dimensions of human-place interaction. This model conceptualizes sense of place as a multidimensional construct, facilitating thematic synthesis and cross-study comparisons. A structured search of Scopus and Web of Science identified 10 studies that met predefined inclusion criteria. Additionally, eight studies with divergent conceptualizations of sense of place were narratively analyzed to explore the diversity of interpretations across disciplinary perspectives in housing research. The review yields three key findings: (1) The expanded tripartite model provides a framework for understanding the relationships between residents and housing. (2) Sense of place is both a criterion and a catalyst for housing sustainability. (3) The development of a sense of place is influenced by the interaction of physical, spatial, environmental, social, cultural, economic, and institutional housing factors. Sense of place provides insight into how housing becomes home, informing context-dependent strategies that enhance place-based connections and contribute to housing sustainability.Science Citation Index Expanded - Social Science Citation Inde

Classification of Morphological Variations of Mandibular Condyle in Panoramic Radiographs with a Deep Learning Approach
No full textAim This study aims to employ the YOLO algorithm for the automatic classification of mandibular condylar morphology in panoramic radiographs. Materials and Methods A total of 1,056 panoramic radiographs, containing 2,112 healthy mandibular condyles, were used in the study. The dataset was split into training (similar to 80%), validation (similar to 10%), and test (similar to 10%) sets. Two experienced dentomaxillofacial radiologists annotated the training images and classified the condyles into four morphological categories: Round, Angled, Diamond, and Crooked Finger-shaped. The YOLOv8 deep learning model was trained using transfer learning, hyperparameter tuning, and fine-tuning techniques. Performance was assessed using metrics including precision, recall (sensitivity), F1-score, mean Average Precision (mAP), and training time. True positives, false positives, and false negatives were evaluated based on bounding box localization and class assignments. Results The model demonstrated balanced performance across classes in the training dataset. On the test dataset, the model achieved an overall F1-score of 0.769 and [email protected] of 0.786. The highest performance was observed for the Crooked Finger class (0.795 precision, 0.870 recall, 0.831 F1-score, 0.837 [email protected]) and the Angled class (0.723 precision, 0.860 recall, 0.786 F1-score, 0.808 [email protected]). The Round class showed moderate results with 0.677 precision, 0.870 recall, 0.761 F1-score, and 0.798 [email protected]. The Diamond class had the lowest performance, with 0.528 precision, 0.696 recall, 0.600 F1-score, and 0.661 [email protected]. Conclusion The model effectively distinguishes the Angled and Crooked Finger classes but faces challenges with the Diamond and Round classes. Despite varied performance, the model demonstrates balanced performance overall, providing a foundation for further refinement and optimization.Science Citation Index Expande

No full textAydin, Gamze/0000-0002-4952-2825;AimNomophobia, a new concept born out of digital addictions, refers to the anxiety and fear that individuals experience when they are away from their cell phones. The aim of this study is to examine the effects of nomophobia and screen addiction on musculoskeletal problems and cardiovascular risk in university students and to reveal the relationship between these parameters.Subjects and methodsThe study adopted a cross-sectional design and included 293 participants (mean age: 21.29 +/- 2.20 years, 76.1% female). The presence of nomophobia was assessed using the Nomophobia Questionnaire (NMP-Q); screen addiction was assessed using the Smartphone Addiction Scale-Short Form (SAS-SF) and the Multiple Screen Addiction Scale (MSAS); musculoskeletal risk level was assessed using the Cornell Musculoskeletal Disorders Questionnaire (CMDQ); cardiovascular risk level was assessed using the Framingham Risk Score (FRS).ResultsParticipants had been using smartphones for 8.19 +/- 2.74 years, with a daily usage time of 6.64 +/- 3.38 h. The mean scores for NMP-Q, SAS, MSAS, and FRS were 74.51 +/- 31.74, 29.40 +/- 12.18, 39.37 +/- 13.14, and -1.16 +/- 5.00 respectively. The highest prevalence of musculoskeletal problems by body region was reported in the neck (71.7%), back (72.4%), and low back (68.6%). Significant differences were observed in the neck (p = 0.049) and back (p = 0.004), with severity increasing as nomophobia levels progressed. A significant positive correlation was found between NMP-Q scores and both SAS-SF (r = 0.560, p < 0.001) and MSAS (r = 0.468, p < 0.001). Regarding musculoskeletal pain, NMP-Q scores showed a significant positive correlation only with back pain (r = 0.166, p < 0.001).ConclusionThis study highlights the significant asSociation between nomophobia and musculoskeletal problems, particularly neck and back pain, among university students.Emerging Sources Citation Inde

Search for Heavy Long-Lived Charged Particles with Large Ionization Energy Loss in Proton-Proton Collisions at s = 13 TeV
No full textA search for heavy, long-lived, charged particles with large ionization energy loss within the silicon tracker of the CMS experiment is presented. A data set of proton-proton collisions at a center of mass energy at s = 13 TeV, collected in 2017 and 2018 at the CERN LHC, corresponding to an integrated luminosity of 101 fb−1, is used in this analysis. Two different approaches for the search are taken. A new method exploits the independence of the silicon pixel and strips measurements, while the second method improves on previous techniques using ionization to determine a mass selection. No significant excess of events above the background expectation is observed. The results are interpreted in the context of the pair production of supersymmetric particles, namely gluinos, top squarks, and tau sleptons, and of the Drell-Yan pair production of fourth generation (τ′) leptons with an electric charge equal to or twice the absolute value of the electron charge (e). An interpretation of a Z’ boson decaying to two τ′ leptons with an electric charge equal to 2e is presented for the first time. The 95% confidence upper limits on the production cross section are extracted for each of these hypothetical particles. © 2025 Elsevier B.V., All rights reserved.Science Citation Index Expande
Cross-Cultural Adaptation and Psychometric Validation of the Turkish Version of the American Orthopaedic Foot and Ankle Society Lesser Metatarsophalangeal-Interphalangeal Joint Scale
No full textObjective: Lesser toe disorders can cause significant functional impairment and pain, requiring reliable tools for outcome assessment. The American Orthopaedic Foot and Ankle Society (AOFAS) lesser metatarsophalangeal-interphalangeal (MTP-IP) joint scale is a clinician-based instrument frequently used in foot and ankle evaluations, yet no validated Turkish version exists. The aim of this study was to translate, culturally adapt, and evaluate the psychometric properties of the Turkish version of the AOFAS lesser MTP-IP scale. Methods: The scale was translated following international cross-cultural adaptation guidelines. A total of 43 patients with various lesser-toe pathologies were assessed using the AOFAS lesser MTP-IP, foot and ankle ability measure (FAAM), visual analogue scale, and short form-12 (SF-12). Test-retest reliability was assessed by calculating intraclass correlation coefficients [ICC (2,1)] using a two-way mixed-effects model with absolute agreement; by assessing internal consistency via Cronbach's alpha; and by evaluating agreement using Bland-Altman analysis. Construct validity was tested by correlating AOFAS scores with FAAM and SF-12 subscales. Floor and ceiling effects were also analyzed. Results: The Turkish version demonstrated excellent test-retest reliability [ICC (2,1)=0.96] and acceptable internal consistency (alpha=0.76). Bland-Altman plots revealed no systematic bias. Strong correlations were observed with FAAM-activities of daily living (r=0.93) and FAAM-sports (r=0.75), whereas correlations with SF-12 physical component summary (r=0.34) and MCS (r=0.45) were weak but significant, which is consistent with the hypothesized convergent and divergent validity. A notable ceiling effect was identified in the AOFAS function and alignment domains, consistent with the high functional status and low pain levels reported by participants. Conclusion: The Turkish adaptation ofthe AOFAS lesser MTP-IP scale is a reliable and valid instrumentfor evaluating pain, function, and alignment in patients with lesser toe disorders. Its strong psychometric performance supports its use in both clinical and research settings, although the observed ceiling effect should be interpreted in the context of patient characteristics.Emerging Sources Citation Inde
Study of Same-Sign W Boson Scattering and Anomalous Couplings in Events With One Tau Lepton from PP Collisions at TeV
No full textA first study is presented of the cross section for the scattering of same-sign W boson pairs via the detection of a τ lepton. The data from proton-proton collisions at the center-of-mass energy of 13 TeV were collected by the CMS detector at the LHC, and correspond to an integrated luminosity of 138 fb−1. Events were selected that contain two jets with large pseudorapidity and large invariant mass, one τ lepton, one light lepton (e or μ), and significant missing transverse momentum. The measured cross section for electroweak same-sign WW scattering is times the standard model prediction. In addition, a search is presented for the indirect effects of processes beyond the standard model via the effective field theory framework, in terms of dimension-6 and dimension-8 operators. © The Author(s) 2025

Rheb1 Signaling and the Fate of Pancreatic Β Cells: Toward a New Frontier in Diabetes Therapy
No full textA recent study in the World Journal of Diabetes by Yang et al explored how Rheb1 signaling influenced pancreatic beta cell fate and its potential as a therapeutic target. This invited commentary by a senior diabetes researcher discussed the findings of Yang et al in the context of current knowledge on beta cell biology, providing critical insight into the role of Rheb1 in beta cell survival and function and the prospects for diabetes treatment. Key outcomes of the study were interpreted alongside established literature on Rheb1- mechanistic target of rapamycin signaling in islet cells. Rheb1 emerges as a pivotal regulator of beta cell growth and insulin secretory function, aligning with evidence that beta cell-specific Rheb1 deletion impairs beta cell mass and glucose-stimulated insulin secretion. The commentary highlighted how modulating this pathway could preserve or restore the beta cell population in diabetes while cautioning about potential off-target effects (e.g. in alpha cells). Targeting Rheb1 signaling represents a promising new frontier in diabetes therapy to enhance beta cell resilience; however, a balanced approach addressing both its benefits and risks is essential. This letter discussed the scientific implications and future research directions needed to translate Rheb1 modulation into clinical application for diabetes.Science Citation Index Expande
