Exercise Addiction in Older Adults: Health Preservation or Fear of Death
(John Wiley and Sons Inc, 2026) Sürenkök, O.; Kendal, K.; Aydln, G.; Atici, E.
Objectives: The aim of the study is to explore exercise addiction in older adults and the psychological, social and biological factors underlying the exercise addiction. Subjects and Methods: This study employed a cross-sectional design. 254 participants aged 65 and above were divided into exercise addicted and non-exercise addicted groups in the study. The exercise addiction of participants was assessed using the Exercise Addiction Inventory (EAI). Health-preserving behaviours were evaluated with the Health Protection Behaviour Scale (HPBS). Anxiety related to health was measured using the Health Anxiety Inventory (HAI), while death anxiety was assessed using the Death Anxiety Scale (DAS). Results: In intergroup analyses, the EAI, HPBS and TDAS scores were higher in the Exercise Addicted Group compared to the Non-Exercise Addicted Group (p < 0.001, p < 0.001, p = 0.009, respectively). However, the HAI score was lower in the Exercise Addicted Group (p = 0.021). In addition, a positive correlation was observed between HPBS and EAI scores (r = 0.454, p < 0.001). No correlation was found between EAI scores and age (r = 0.028, p = 0.654) or HAI (r = −0.088, p = 0.162). Conclusions: This study found that individuals with exercise addiction had lower BMI, a lower proportion of women and higher education levels. Additionally, while positive relationships were observed between exercise addiction and both health-protective behaviours and death anxiety, a negative relationship was found with health anxiety. Correlation and regression analyses indicated that BMI and higher education level serve as protective factors against exercise addiction, whereas health-protective behaviours and death anxiety function as risk factors. © 2025 Japanese Psychogeriatric Society.

Search for New Physics in Jet Multiplicity Patterns of Multilepton Events at (Formula Presented)
(American Physical Society, 2025) Hayrapetyan, A.; Tumasyan, A.; Adam, W.; Andrejkovic, J.W.; Bergauer, T.; Chatterjee, S.; Damanakis, K.
A first search for beyond the standard model physics in jet multiplicity patterns of multilepton events is presented, using a data sample corresponding to an integrated luminosity of (Formula presented) of 13 TeV proton-proton collisions recorded by the CMS detector at the LHC. The search uses observed jet multiplicity distributions in one-, two-, and four-lepton events to explore possible enhancements in jet production rate in three-lepton events with and without bottom quarks. The data are found to be consistent with the standard model expectation. The results are interpreted in terms of supersymmetric production of electroweak chargino-neutralino superpartners with cascade decays terminating in prompt hadronic (Formula presented)-parity violating interactions. © 2025 CERN, for the CMS Collaboration.

(Assoc. Medica Brasileira, 2025) Torlak, Mustafa Savas; Atici, Emine; Tufekci, Osman; Karaca, Osman; Dursun, Burcu; Tunc, Elif
OBJECTIVE: The aim of this study was to investigate the effect of passive music listening in addition to conventional physiotherapy on pain, anxiety, and quality of life in patients with chronic neck pain. METHODS: The study included 40 people aged 30-50 years with chronic neck pain, who volunteered to participate in it. The participants were randomized into a control group (n=20) and a music group (n=20). Participants in the control group received a classical physiotherapy programme, 5 days a week for 4 weeks. Participants in the music group listened to music through headphones throughout the treatment. RESULTS: At the end of treatment, there was a statistical difference in the Beck Anxiety Inventory, visual analog scale, Neck Disability Index, and SF-36 physical scores in intragroup comparisons in both groups (p<0.05), When comparing the differences between the groups before and after treatment, it was found that the decrease in visual analog scale score of the participants in the music group was statistically significant compared to the decrease in visual analog scale score of the participants in the control group (p<0.01). CONCLUSION: Passive listening to music has been shown to have a positive effect on chronic neck pain when used in addition to conventional physiotherapy.

(American Physical Society, 2025) Tchekhovski, V.; Hayrapetyan, A.; Makarenko, V.; Tumasyan, A.; Adam, W.; Andrejkovic, J.W.; Benato, L.
A search for the rare decay (Formula presented) is reported using proton-proton collision events at (Formula presented) collected by the CMS detector in 2022-2023, corresponding to an integrated luminosity of (Formula presented). This is the first analysis to use a newly developed inclusive dimuon trigger, expanding the scope of the CMS flavor physics program. The search uses (Formula presented) mesons obtained from (Formula presented) decays. No significant excess is observed. A limit on the branching fraction of (Formula presented) at 95% confidence level is set. This is the most stringent upper limit set on any flavor changing neutral current decay in the charm sector. © 2025 CERN, for the CMS Collaboration.
Search for a Neutral Gauge Boson With Nonuniversal Fermion Couplings in Vector Boson Fusion Processes in Proton-Proton Collisions at (Formula Presented)
(American Physical Society, 2025) Hayrapetyan, A.; Tumasyan, A.; Adam, W.; Andrejkovic, J.W.; Benato, L.; Bergauer, T.; Chatterjee, S.
The first search for a heavy neutral spin-1 gauge boson ((Formula presented)) with nonuniversal fermion couplings produced via vector boson fusion processes and decaying to tau leptons or (Formula presented) bosons is presented. The analysis is performed using LHC data at (Formula presented), collected from 2016 to 2018 with the CMS experiment and corresponding to an integrated luminosity of (Formula presented). The data are consistent with the standard model predictions. Upper limits are set on the product of the cross section for production of the (Formula presented) boson and its branching fraction to (Formula presented) or (Formula presented). The presence of a (Formula presented) boson decaying to (Formula presented) ((Formula presented)) is excluded for masses up to 2.45(1.60) TeV, depending on the (Formula presented) boson coupling to standard model weak bosons, and assuming a (Formula presented) ((Formula presented)) branching fraction of 50%. © 2025 CERN, for the CMS Collaboration.
Abnormal Right Ventricular to Pulmonary Artery Coupling in Patients with End-Stage Kidney Disease and Normalization After Renal Transplantation: A Observational Study
(Karger, 2025) Cetin Guvenc, Rengin; Guvenc, Tolga Sinan; Karakaya, Ezgi Sude; Acik, Hasan; Korkmaz, Aysu; Salem, Abdul Fattah; Gurkan, Alp
Introduction: Pulmonary hypertension and right ventricular (RV) dysfunction are associated with an increase in mortality and worse prognosis in patients with end-stage kidney disease (ESKD), but pathophysiologic mechanisms underlying the progression of RV dysfunction remain incompletely understood. The present study aimed to understand right ventricular to pulmonary artery (RV-PA) coupling, which is an early indicator of transition to RV dysfunction, to better characterize adaptive RV response to increased afterload in ESKD patients and changes in RV-PA coupling following renal transplantation. Methods: One hundred eleven patients with ESKD, including 49 patients scheduled for renal transplantation, underwent a detailed echocardiographic examination and measurement of tricuspid annular plane excursion to pulmonary artery systolic pressure (TAPSE/PASP) ratio, and a repeat examination was performed 6 months after the baseline examination. Results: Patients with ESKD had significantly lower TAPSE/PASP ratio at baseline (1.02 [0.71-1.63] vs. 1.29 [1.09-1.96], p < 0.001). In 40 patients that underwent transplantation, TAPSE/PASP ratio increased significantly from (0.97 [0.72-1.42] to 1.30 [1.01-1.82], p = 0.03), while in 27 patients remained on dialysis, there was a nonsignificant reduction in TAPSE/PASP ratio (1.21 [0.71-1.62] vs. 0.84 [0.61-1.38], p = 0.44). The change in TAPSE/PASP ratio correlated significantly with the change in pulmonary vascular resistance (OR: 0.61, 95% CI: 0.51-0.72, p < 0.001) and left ventricular mass index (OR: 0.97, 95% CI: 0.96-0.99, p = 0.001) after adjustment. Conclusions: Patients with ESKD had abnormal RV-PA coupling, as indicated by a reduced TAPSE/PASP ratio, which normalizes 6 months after renal transplantation.
Precise Forecasting of Shear Stress, Viscosity, and Density for an Aqueous CuO/CaCO3 Ternary Hybrid Nanofluid Utilizing the Artificial Neural Network
(Nature Portfolio, 2025) Jin, Yi; Basem, Ali; Al-Nussairi, Ahmed Kateb Jumaah; Kareem, Muthanna K.; Hasanabad, Alimohammadi; Li, Zhenghui; Salahshour, Soheil
The accurate prediction of thermophysical properties in hybrid nanofluids is crucial for enhancing the efficiency of advanced heat transfer and energy conversion systems. Most published research has largely concentrated on single- or binary-nanoparticle systems, and ternary hybrid systems are still poorly understood in terms of interactions. The present study, however, developed two-layer feedforward artificial neural networks to predict shear stress, viscosity, and density for a water-based nanofluid containing copper oxide, calcium carbonate, and silicon dioxide in volume ratios of 60, 30, and 10%, respectively. Training and validation of the networks were based on experimental data collected at temperatures ranging from 25 to 70 degrees C and nanoparticle volume fractions ranging from 0.5 to 3%. That model achieved outstanding predictive performance, with average root-mean-square errors (evaluated via K-fold cross-validation) of 0.0008 Pa for shear stress, 0.0097 mPa s for viscosity, and 0.0003 g/cm(3) for density. Minimum mean squared errors were 1.63 x 10(-)(6), 3.11 x 10(-)(5), and 4.03 x 10(-)(5), respectively, with correlation coefficients over 0.999 across all data sets. The calculated maximum relative errors were 0.71% for shear stress, 1.34% for viscosity, and 0.06% for density, which endorse the reliability and precision of the produced model. Further sensitivity analysis demonstrated that temperature dominance over shear stress and viscosity, although nanoparticle concentration exerted a significantly stronger impact on density. The proposed framework served as an accurate, data-driven tool for modeling ternary hybrid nanofluids, providing practical insights into their optimized formulations for high-performance thermal management applications.
Intuitive Eating, Maternal Attachment, and Weight Status in Postpartum Women: A Cross-Sectional Study
(BMC, 2025) Ayvaz, Begum Ciler; Akin, Pelin; Ede Ileri, Gozde
Background The postpartum period is characterized by significant changes in eating behaviors, emotional regulation and body weight. Intuitive eating and maternal attachment may play a key role in regulating women's weight status during early postpartum. Methods This cross-sectional study was conducted between February and May 2022 in Turkey, involving 264 healthy postpartum women (1-4 months) aged 18-40 years. Sociodemographic information, dietary habits, and anthropometric measurements were collected. Intuitive Eating Scale-2 (IES-2) and Maternal Attachment Scale (MAS) was administered. We classified BMI levels below 25 as "lower BMI"" and above 25 as "higher BMI". Results Of the participants, 45.8% reported eating intuitively. Body mass index (BMI) was significantly higher in those with low levels of intuitive eating behaviour (p = < 0.001). A positive correlation was found between maternal attachment and intuitive eating (r = 0.129, p = 0.037). Higher intuitive eating was associated with lower BMI (beta = -0.269, p = < 0.001). Skipping meals and night eating were associated with lower intuitive eating (p = 0.023). In logistic regression analysis, low intuitive eating (< 3.4 points) was associated with a high BMI during the early postpartum (OR = 2.63; 95% CI 1.57-4.40, p = < 0.001). Conclusions Intuitive eating behaviour is positively associated with maternal attachment. However, higher intuitive eating is associated with lower BMI levels, night eating, and skipping meals. The results suggest that public health counselling promoting intuitive eating may be beneficial for early postpartum women who are at risk of excessive weight gain.
The Impact of Diet and Oral Hygiene on Dental Caries Among Turkish Children: A Cross-Sectional Study
(Public Library Science, 2025) Yesildemir, Ozge; Ozay Sekendiz, Melisa; Agagunduz, Duygu; Budan, Ferenc
Background Dental caries remains one of the most prevalent chronic conditions affecting children worldwide, yet they are largely preventable through modifiable factors such as diet and oral hygiene. This study aimed to examine the associations between dietary intake, oral hygiene practices, anthropometric measurements, and dental caries in children. Methods This cross-sectional study was conducted in Bursa, T & uuml;rkiye, between 1 October 2023 and 20 February 2024 with 210 children aged 5-12 years. Data was collected through a structured questionnaire on sociodemographic factors, oral hygiene, and a food frequency questionnaire related to dental health. Body weight and height were measured, and dental examinations were performed by a trained dentist using DMFT/dmft indices. Results Mean DMFT and dmft scores were 0.9 +/- 1.3 and 3.9 +/- 2.8, respectively. Children who brushed their teeth had significantly lower caries scores (p < 0.001); brushing twice daily was associated with lower dmft scores (p < 0.001). Caries scores did not differ significantly by body mass index (p > 0.05). Higher DMFT scores were associated with citrus fruits (beta = 0.322, p < 0.001), white bread (beta = 0.423, p < 0.001), and fruit juice (beta = 0.050, p < 0.05) consumption. Higher dmft scores were linked to chocolate (beta = 0.286), biscuits, cookies, and cakes (beta = 0.448), chips (beta = 0.179), and carbonated soft drinks (beta = 0.789) (p < 0.001). Conclusions These results highlight the importance of promoting healthy eating and proper oral hygiene to prevent childhood dental caries and suggest that early oral health status may have broader implications for long-term systemic health, warranting further longitudinal investigation.
Rheb1 Signaling and the Fate of Pancreatic Β Cells: Toward a New Frontier in Diabetes Therapy
(Baishideng Publishing Group Inc, 2025) Karimkhani, Hadi
A 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.
Association of Tonsillolith Characteristics With Periodontal Bone Loss and Dental Pathologies: A Retrospective Study Based on Cone-Beam Computed Tomography
(Nature Portfolio, 2025) Ustaoglu, Gulbahar; Bulut, Duygu Goller; Aydin, Banu
Tonsilloliths are frequently detected as incidental findings, and their microbial similarity to periodontal biofilms suggests potential clinical significance, although robust CBCT-based evidence supporting this association has been limited. This retrospective study evaluated the association between the presence, size, and number of tonsilloliths detected on cone-beam computed tomography (CBCT) images and periodontal bone loss, furcation involvement, and other dental pathologies. CBCT scans of 342 systemically healthy patients obtained between November 2020 and October 2024 were retrospectively evaluated. Participants were divided into two equal groups (n = 171) according to the presence of tonsilloliths, and each scan was assessed for tonsillolith characteristics and dental findings. Periodontal bone loss was determined from cementoenamel junction-alveolar crest distances and categorized into three severity levels. Tonsilloliths were most frequently located on the right side or bilaterally, with a mean size of 3.98 +/- 1.78 mm. The tonsillolith group had a significantly higher mean number of missing teeth (p = 0.040), while no significant differences were noted for decayed, restored teeth, or apical periodontitis. Bone loss between 1/3 and 2/3 of the optimal bone height and bone loss more than 2/3 of the optimal bone height were more prevalent in the tonsillolith group (p < 0.001). Tonsillolith size positively correlated with bone loss severity (rho = 0.274, p < 0.001), and larger tonsilloliths were significantly associated with furcation defects (p < 0.001). Tonsillolith presence and size may be linked to advanced periodontal bone loss and tooth loss, highlighting the potential role of CBCT in interdisciplinary periodontal assessment.
Gemini 1.5 Flash Provides the Most Reliable Content While ChatGPT-4o Offers the Highest Readability for Patient Education on Meniscal Tears
(Wiley, 2025) Cakmur, Basar Burak; Koluman, Ali Can; Ciftci, Mehmet Utku; Ciftci, Ebru Aloglu; Ziroglu, Nezih
Purpose The aim of this study was to comparatively evaluate the responses generated by three advanced artificial intelligence (AI) models, ChatGPT-4o (OpenAI), Gemini 1.5 Flash (Google) and DeepSeek-V3, to frequently asked patient questions about meniscal tears in terms of reliability, usefulness, quality, and readability. Methods Responses from three AI chatbots, ChatGPT-4o (OpenAI), Gemini 1.5 Flash (Google) and DeepSeek-V3 (DeepSeek AI), were evaluated for 20 common patient questions regarding meniscal tears. Three orthopaedic specialists independently scored reliability and usefulness on 7-point Likert scales and overall response quality using the 5-point Global Quality Scale. Readability was analysed with six established indices. Inter-rater agreement was examined with intraclass correlation coefficients (ICCs) and Fleiss' Kappa, while between-model differences were tested using Kruskal-Wallis and ANOVA with Bonferroni adjustment. Results Gemini 1.5 Flash achieved the highest reliability, significantly outperforming both GPT-4o and DeepSeek-V3 (p = 0.001). While usefulness scores were broadly similar, Gemini was superior to DeepSeek-V3 (p = 0.045). Global Quality Scale scores did not differ significantly among models. In contrast, GPT-4o consistently provided the most readable content (p < 0.001). Inter-rater reliability was excellent across all evaluation domains (ICC > 0.9). Conclusion All three AI models generated high-quality educational content regarding meniscal tears. Gemini 1.5 Flash demonstrated the highest reliability and usefulness, while GPT-4o provided significantly more readable responses. These findings highlight the trade-off between reliability and readability in AI-generated patient education materials and emphasise the importance of physician oversight to ensure safe, evidence-based integration of these tools into clinical practice.
Mxenes in Diabetes: Diagnostic and Therapeutic Applications
(Royal Society Chemistry, 2025) Samadzadeh, Meisam; Danesh, Mahshid; Zarepour, Atefeh; Khosravi, Arezoo; Zarrabi, Ali; Iravani, Siavash
This review highlights the promising role of MXenes and their composites in diabetes management, emphasizing their dual utility in diagnostics and therapeutics. MXenes' exceptional electrical conductivity, hydrophilicity, mechanical robustness, and tunable surface chemistry facilitate the design of sensitive and selective biosensors for real-time and non-invasive monitoring of key diabetes biomarkers like glucose and acetone. Therapeutically, MXene-based materials enhance healing of diabetic complications such as foot ulcers by modulating inflammation, scavenging reactive oxygen species, promoting angiogenesis, and supporting tissue regeneration via multifunctional hydrogels, patches, and scaffolds. Despite these advances, challenges remain including environmentally harmful synthesis methods, limited scalability, oxidation-induced instability under physiological conditions, and insufficient biocompatibility data. Future efforts are directed toward developing greener and scalable synthesis routes, improving MXene stability through surface modifications, and integrating MXenes with cutting-edge technologies such as wearable devices, 3D bioprinting, and bioelectronics. Additionally, the review uniquely explores the incorporation of artificial intelligence and machine learning techniques to enable personalized and adaptive diabetes management. By providing a comprehensive synthesis of recent developments, current limitations, and innovative future directions, this review offers novel insights aimed at accelerating the clinical translation of MXene-based platforms to significantly enhance diabetes diagnosis and treatment.
Observation of Λ Hyperon Local Polarization in P-Pb Collisions at √sNN=8.16 TeV
(American Physical Society, 2025) Hayrapetyan, A.; Tumasyan, A.; Adam, W.; Andrejkovic, J. W.; Benato, L.; Bergauer, T.; Druzhkin, D.
The polarization of the Lambda and (Lambda) over bar hyperons along the beam direction has been measured in proton-lead (p-Pb) collisions at a center-of-mass energy per nucleon pair of 8.16 TeV. The data were obtained with the CMS detector at the LHC and correspond to an integrated luminosity of 186.0 +/- 6.5 nb(-1). A significant azimuthal dependence of the hyperon polarization, characterized by the second-order Fourier sine coefficient P-z,P-s2, is observed. The P-z,P-s2 values decrease as a function of charged particle multiplicity, but increase with transverse momentum. A hydrodynamic model that describes the observed P-z,P-s2 values in nucleus-nucleus collisions by introducing vorticity effects does not reproduce either the sign or the magnitude of the p-Pb results. These observations pose a challenge to the current theoretical implementation of spin polarization in heavy ion collisions and offer new insights into the origin of spin polarization in hadronic collisions at LHC energies.
The Effect of Fluoride Varnish on the Color Stability and Surface Microhardness of Bioactive Restorative Materials: An in Vitro Study
(Sage Publications Ltd, 2025) Tarac, Mihriban Gokcek; Cam, Melek
The aim of the study is to evaluate the effect of fluoride varnishes on both the color stability and surface microhardness of different fluoride-releasing restorative materials exposed to beverages commonly consumed by children . This study was conducted as an in vitro experimental study design. Three different restorative materials (Dyract XP, Beautifil II, and Cention N) and a colorless fluoride varnish were used. The solutions in which the samples were immersed were selected as beverages commonly preferred by children: cherry juice, chocolate milk, and cola. Color changes of the samples were measured using a spectrophotometer at 1, 7, 14, and 28 days and calculated according to the CIEDE2000 total color difference formula. Surface microhardness values were measured using a digital microhardness testing device at 1 and 28 days. To assess the effects of variables and their interactions in repeated observation designs, generalized linear models and generalized linear mixed models were fitted. Following model estimation, Tukey's-adjusted estimated marginal means were computed to identify significant pairwise differences. Fluoride-releasing restorative materials exhibited varying degrees of color change and decrease in surface microhardness when immersed in different staining solutions. Among the tested materials, Cention N demonstrated the greatest color stability (Delta E=1.01 for fluoride applied group, Delta E=1.45 for the group without fluoride application) and least reduction in surface microhardness. Fluoride application initially caused a slight discoloration immediately after application. However, following immersion in different solutions, fluoride application appeared to enhance color stability (Delta E=1.59 in the varnish-applied group, Delta E=2.21 in the group without varnish application), but did not have a statistically significant effect on the surface microhardness. A negative correlation was observed between color change and surface microhardness; as the surface microhardness decreased, the extent of color change increased. This study highlights the prominent role of intraoral environmental factors in influencing the durability and aesthetic properties of fluoride-releasing restorative materials. Topical fluoride application has a beneficial effect on the color stability with a more pronounced effect observed with Cention N.
Evidence for Similar Collectivity of High Transverse-Momentum Particles in P-Pb and Pb-Pb Collisions
(American Physical Society, 2025) Chekhovsky, V.; Hayrapetyan, A.; Makarenko, V.; Tumasyan, A.; Adam, W.; Andrejkovic, J. W.; Druzhkin, D.
Charged hadron elliptic anisotropies (v(2)) are presented over a wide transverse momentum (p(T)) range for proton-lead (pPb) and lead-lead (PbPb) collisions at nucleon-nucleon center-of-mass energies of 8.16 and 5.02 TeV, respectively. The data were recorded by the CMS experiment and correspond to integrated luminosities of 186 and 0.607 nb(-1) for the pPb and PbPb systems, respectively. A four-particle cumulant analysis is performed using subevents separated in pseudorapidity to effectively suppress noncollective effects. At high pT (p(T) > 8 GeV), significant positive v(2) values that are similar between pPb and PbPb collisions at comparable charged particle multiplicities are observed. This observation suggests a common origin for the multiparticle collectivity for high-p(T) particles in the two systems.
The Influence of Clinician Experience on the Primary Stability of Tri-Oval Versus Standard Parallel-Walled Implants Placed Using Different Surgical Protocols: An Ex Vivo Study
(Quintessence Publishing Co Inc, 2025) Cakir, Merve; Ulker, Gul Merve Yalcin; Saygili, Sina; Durgun, Mehmet Akif; Dayan, Suleyman Cagatay; Kan, Bahadir; Geckili, Onur
Purpose: To investigate the effect that clinical experience has on implant primary stability using insertion torque (IT) and resonance frequency analysis (RFA) from two different drilling protocols: (1) implant-specific osteotomy protocol and (2) conventional drilling. Materials and Methods: A total of 60 tri-oval and 60 parallel-walled implants were placed in fresh bovine ribs by three clinicians (B.K., M.& Ccedil;., and M.A.D), who were classified according to the total number of implants they had previously placed. Tri-oval implants were placed with an implant-specific osteotomy protocol, and parallel implants were placed with conventional drilling. The ITs of the implants were measured by the same clinician who performed the operation. An independent examiner (O.G.) measured the RFA of all implants after placement via a resonance frequency analyzer. Results: In the IT evaluation, no statistical significance was observed between the clinicians and both tri-oval implants and parallel implants (P = .293 and P = .98, respectively); in all experience levels, the ITs were significantly lower in parallel implants. Additionally, across all experience levels, tri-oval implants demonstrated greater RFA values than parallel implants (P = .001). Within-group comparisons of RFA by experience level for the tri-oval implants did not show a statistically significant difference (P = .950). However, in parallel implants, there was a significant difference between the moderately experienced and inexperienced groups (P = .019). Conclusions: The implant-specific osteotomy procedure with tri-oval implants offers greater primary stability compared to conventional osteotomy with parallel-walled implants, regardless of the clinician's experience.
Measurement of WWZ and ZH Production Cross Sections at √s=13 and 13.6 TeV
(American Physical Society, 2025) Hayrapetyan, A.; Makarenko, V.; Tumasyan, A.; Adam, W.; Andrejkovic, J. W.; Benato, L.; Choi, J.
A measurement is presented of the cross section in proton-proton collisions for the production of two W bosons and one Z boson. It is based on data recorded by the CMS experiment at the CERN LHC at center-of-mass energies root s = 13 and 13.6 TeV, corresponding to an integrated luminosity of 200 fb(-1). Events with four charged leptons (electrons or muons) in the final state are selected. Both nonresonant WWZ production and ZH production, with the Higgs boson decaying into two W bosons, are reported. For the first time, the two processes are measured separately in a simultaneous fit. Combining the two modes, signal strengths relative to the standard model (SM) predictions of 0.75(-0.29)(+0.34) and 1.74(-0.60)(+0.71) are measured for root s = 13 and 13.6 TeV, respectively. The observed (expected) significance for the triboson signal is 3.8 (2.5) standard deviations for root s = 13.6 TeV, thus providing the first evidence for triboson production at this center-of-mass energy. Combining the two modes and the two center-of-mass energies, the inclusive signal strength relative to the SM prediction is measured to be 1.03(-0.28)(+0.31), with an observed (expected) significance of 4.5 (5.0) standard deviations.
Observation of the Charged-Particle Multiplicity Dependence of Σψ(2s)/Σj in P-Pb Collisions at 8.16 TeV
(American Physical Society, 2025) Chekhovsky, V.; Hayrapetyan, A.; Makarenko, V.; Tumasyan, A.; Adam, W.; Andrejkovic, J. W.; Dutta, S.
Bound states of charm and anticharm quarks, known as charmonia, have a rich spectroscopic structure that can be used to probe the dynamics of hadron production in high-energy hadron collisions. Here, the cross section ratio of excited (psi(2S)) and ground state (J/psi) vector mesons is measured as a function of the charged-particle multiplicity in proton-lead (pPb) collisions at a center-of-mass (CM) energy per nucleon pair of 8.16 TeV. The data corresponding to an integrated luminosity of 175 nb(-1) were collected using the CMS detector. The ratio is measured separately for prompt and nonprompt charmonia in the transverse momentum range 6.5 < p(T) < 30 GeV and in four rapidity ranges spanning -2.865 < y(CM) < 1.935. For the first time, a statistically significant multiplicity dependence of the prompt cross section ratio is observed in proton-nucleus collisions. There is no clear rapidity dependence in the ratio. The prompt measurements are compared with a theoretical model which includes interactions with nearby particles during the evolution of the system. These results provide additional constraints on hadronization models of heavy quarks in nuclear collisions.
