Measurements of Observables Sensitive To Colour Reconnection in Tt¯ Events With the Atlas Detector at √s= 13 Tev
No full textA measurement of observables sensitive to effects of colour reconnection in top-quark pair-production events is presented using 139 fb - 1 of 13 TeV proton–proton collision data collected by the ATLAS detector at the LHC. Events are selected by requiring exactly one isolated electron and one isolated muon with opposite charge and two or three jets, where exactly two jets are required to be b-tagged. For the selected events, measurements are presented for the charged-particle multiplicity, the scalar sum of the transverse momenta of the charged particles, and the same scalar sum in bins of charged-particle multiplicity. These observables are unfolded to the stable-particle level, thereby correcting for migration effects due to finite detector resolution, acceptance and efficiency effects. The particle-level measurements are compared with different colour reconnection models in Monte Carlo generators. These measurements disfavour some of the colour reconnection models and provide inputs to future optimisation of the parameters in Monte Carlo generators. © 2023, The Author(s).IN2P3-CNRS; 2014-2021; SCI/013; U.S. Department of Energy, USDOE; Alexander von Humboldt-Stiftung, AvH; CRC Health Group, CRC: 21/SCI/017; Canarie; H2020 Marie Skłodowska-Curie Actions, MSCA; Multiple Sclerosis Scientific Research Foundation, MSSRF; CERN; Compute Canada; Göran Gustafssons Stiftelser; Natural Sciences and Engineering Research Council of Canada, NSERC; National Research Council Canada, NRC; Canada Foundation for Innovation, CFI; Science and Technology Facilities Council, STFC; Leverhulme Trust; European Research Council, ERC; European Cooperation in Science and Technology, COST; Australian Research Council, ARC; National Stroke Foundation, NSF; Neurosurgical Research Foundation, NRF; Helmholtz-Gemeinschaft, HGF; Minerva Foundation; Deutsche Forschungsgemeinschaft, DFG; Agence Nationale de la Recherche, ANR; Japan Society for the Promotion of Science, KAKEN; Ministry of Education, Culture, Sports, Science and Technology, MEXT; Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung, SNF; Danmarks Grundforskningsfond, DNRF; Fundação de Amparo à Pesquisa do Estado de São Paulo, FAPESP; National Natural Science Foundation of China, NSFC; Ministerstvo Školství, Mládeže a Tělovýchovy, MŠMT; Fundação para a Ciência e a Tecnologia, FCT; Bundesministerium für Bildung und Forschung, BMBF; Chinese Academy of Sciences, CAS; Austrian Science Fund, FWF; Generalitat de Catalunya; Ministry of Science and Technology of the People's Republic of China, MOST; Agencia Nacional de Promoción Científica y Tecnológica, ANPCyT; Nederlandse Organisatie voor Wetenschappelijk Onderzoek, NWO; Bundesministerium für Wissenschaft, Forschung und Wirtschaft, BMWFW; Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq; Nella and Leon Benoziyo Center for Neurological Diseases, Weizmann Institute of Science; Israel Science Foundation, ISF; Instituto Nazionale di Fisica Nucleare, INFN; Narodowe Centrum Nauki, NCN; Javna Agencija za Raziskovalno Dejavnost RS, ARRS; Ministarstvo Prosvete, Nauke i Tehnološkog Razvoja, MPNTR; Ministerio de Ciencia e Innovación, MICINN; Centre National pour la Recherche Scientifique et Technique, CNRST; Staatssekretariat für Bildung, Forschung und Innovation, SBFI; Horizon 2020; British Columbia Knowledge Development Fund, BCKDF; European Regional Development Fund, ERDF; Defence Science Institute, DSI; Narodowa Agencja Wymiany Akademickiej, NAWA; Institutul de Fizică Atomică, IFA; Agencia Nacional de Investigación y Desarrollo, ANID; Royal Society of South Australia, RSSA; Irish Rugby Football Union, IRFUWe thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently.

Peripapillary and Macular Choroidal Vascularity Index in Migraine Patients During Acute Attacks
No full textPurpose: To evaluate the choroidal vascularity alterations of macula and peripapillary area in migraine patients during acute migraine attacks and compare with control group participants. Methods: A total of 28 patients diagnosed with migraine (24 female and 4 male) and 28 age matched-healthy controls (21 female and 7 male) were included in this cross-sectional study. Enhanced depth imaging optical coherence tomography scans of the macula and peripapillary regions were analyzed. Images were binarized using ImageJ software (National Institutes of Health, Bethesda, MD, USA) (Figure 1). The choroidal thickness (CT), total choroidal area (TCA), luminal area (LA), stromal area (SA), and the choroidal vascularity index (CVI) were compared between the groups. Results: The subfoveal and 750 microns nasal (N750) and temporal (T750) to the fovea CT were increased in migraine patients (P=0.004, P0.001 and P0.001, respectively). The mean subfoveal CVI value was 65.7 ± 6.8 in migraine patients and 63.6 ± 4.8 in healthy controls (P=0.159). The mean peripapillary CT at the temporal, nasal, and inferior regions were increased in migraine group (P=0.010, P0.001 and P0.001, respectively). The mean CVI values of temporal and nasal quadrant in the peripapillary region were significantly increased in the migraine group as compared with the control group (P=0.005 and P0.001, respectively). The increase TCA and LA in both fovea and peripapillary regions were statistically significant in migraine group compared to healthy controls (P0.05 for all). Both groups had similar measured values for other parameters (P >0.05 for all). Conclusion: According to our findings, increased CT, TCA, LA and CVI values may indicate a rebound vasodilatation in the ocular blood flow, as in the vasogenic theory contributing to pain

Talon Cannulated Compression Device as an Alternative in the Fixation of Acetabulum Posterior Column Fractures: a Biomechanical Study
No full textTo compare the amount of displacement and rigidity at the fracture line under static ; dynamic axial loading and torsional stress of conventional cannulated screw (CS), plate screw fixation including inter-fragmentary screw (PL), and talon cannulated compression device or talon screw in other words (TS) in posterior column fracture models. Synthetic hemipelvis bone models presenting a posterior column fracture were used in this study. Group PL, CS, and TS were created with ten bone models prepared for each group for dynamic and static loading tests and another ten for torsional tests. Rigidity and displacement amounts before and after loading were measured at the reference points AL, BL, and CL, located at the acetabulum's top, middle, and bottom, respectively. Torsional tests for each group were used to calculate torsional rigidity and maximum torque values. In dynamic axial loading tests, Group CS showed more displacement than PL at the BL point (p = 0,032) and Group TS at AL (p = 0,032) and CL (p = 0,004) points. In static axial loading tests, Group CS significantly displaced more than TS at AL and CL points (p = 0,05 and p = 0,014, respectively). Group PL and Group TS exhibited similar behavior in dynamic, static axial loading tests and torsional rigidity. The maximum torque that Group PL could withstand was statistically significantly higher than the other two groups (p 0,001). Talon cannulated screws had promising results in posterior column fractures of the acetabulum, which may decline the need for open surgery for stable fixation

Spoofing Detection and Anti-Spoofing Kalman Filter Design for an Accelerometer-Integrated Gnss Receiver
No full text31st IEEE Conference on Signal Processing and Communications Applications (SIU) -- JUL 05-08, 2023 -- Istanbul Tech Univ, Ayazaga Campus, Istanbul, TURKEYGlobal Navigation Satellite Systems (GNSS) measurements are frequently used, especially in autonomous vehicle navigation, as they can provide successful positioning solutions. Therefore, the importance of positioning accuracy of the GNSS receiver in these vehicles has increased. On the other hand, with spoofing attacks, receivers can produce a positioning solution in a way that they think they are in a different place than their actual location. For this reason, it is important to use spoofing detection and countermeasure algorithms in GNSS receivers. In this paper, a Kalman filter design is proposed to be used in the navigation block, just before producing the final positioning solution, of the accelerometer-integrated GNSS receivers for spoofing detection and countermeasure. The proposed approach detects spoofing by comparing the residual values of the solutions of accelerometers and GNSSs with each other. The performance of the filter was examined with Monte Carlo simulations for different spoofing trajectories and interpreted by plotting Receiver Operating Characteristic curves.IEEE,TUBITAK BILGEM,Turkcel

Design and Synthesis of Some Arylhydrazone Derivatives as Potential Faah Inhibitors
No full textObjective: The aim was to design, synthesis and investigation of possible interactions in the enzyme active site of a series of arylhydrazone derivatives for the inhibition of the FAAH enzyme.” Material and Method: Arylhydrazone derivatives were obtained through the reaction of nicotinic hydrazide or benzohydrazide with appropriate aldehyde derivatives, and the obtained crude product was recrystallized from ethanol. After elucidating chemical structures of the compounds via spectroscopic methods, the inhibitory activities against hFAAH were screened. The results were further supported with molecular modeling studies. Result and Discussion: In this study, a new series of seven arylhydrazone derivatives were screened against hFAAH. 4-phenoxyphenyl bearing derivative 5 was found to inhibit hFAAH 40 % at 10 µM which indicates that newly developed inhibitor could serve as a starting point for improving inhibitory effect of the new series. © 2023 University of Ankara.

The Role of Honor Concerns in Disclosing (vs. Hiding) Covid-19 Diagnosis: Insights From Turkiye
No full textMembers of honor cultures value engaging in moral behaviors and managing their social image to maintain their honor. These two goals reflect reputation and integrity concerns, which also have bearing on gender roles. In the current study, we examined a) evaluations of women and men described as diagnosed with COVID-19 and as either hiding or disclosing their diagnosis, b) the moderating role of honor concerns (reputation and integrity) and the gender of the infected person in these evaluations, and c) the relationship between honor concerns and individuals' own disclosure preferences among participants living in Turkiye, a country that exemplifies an honor culture. Findings revealed that participants with stronger reputation concerns evaluated a woman's hiding behavior more favorably than that of a man's. Moreover, higher integrity concerns were associated with lower levels of participants' own preference to hide a diagnosis for both men and women, whereas reputation concerns were positively associated with a preference for hiding a diagnosis among men only. Furthermore, a content analysis of participants' open-ended explanations of their views on women's and men's motivation to hide a diagnosis revealed further evidence for the gendered nature of reputation concerns. Our findings point to the importance of prioritizing integrity concerns (and downplaying reputation concerns) in public health campaigns in honor cultures
