The g-factor of the CHARGED LEPTONs has always been considered by many physicists, both experimentaly as well as theoretically. In fact the electron and muon g-factor play the main role in testing the QED as well as the standard model. Meanwhile, there is a discrepancy between the standard model prediction of the muon anomalies MAGNETIC MOMENT and its experimental determination as large as (25.5±8.0) ×10-10.Therefore the g-factor can be used as the best place to study the new physics beyond the standard model. In this article, we consider the g-factor of the LEPTON in the noncommutative space time as a new physics model. In the ordinary theory, Schwinger evaluated the first correction to the g-factor of free electron, which arises from the electron interaction with photon at one loop level in the QED. In noncommutative space time, we show that at one loop, there is an NC-contribution to the g-factor of LEPTONs which leads to a new bound on the noncommutative parameter (NC parameter). The obtained bounds are comparable with the current bounds on the NC-parameters of the order TeV.

Progressive collapse studies generally assess the performance of the structure under gravity and blast loads, while earthquakes may also lead to the progressive collapse of a damaged structure. In this study, the progressive collapse response of concentrically braced dual systems with steel MOMENT-resisting frames was assessed under seismic loads through pushover analysis using triangular and uniform lateral load patterns. Two different bracing types (X and inverted V braces) were considered, and their performances were compared under different lateral load patterns using the nonlinear static alternate path method recommended in the Unified Facilities Criteria (UFC) guideline. Eventually, the seismic progressive collapse resistance of models was compared to their progressive collapse response under gravity loads. These studies showed that models under the seismic progressive collapse loads satisfied UFC acceptance criteria and limited rehabilitation objective. The structures had better performance under seismic progressive collapse than models under gravity loads because of more resistance, ductility, suitable load redistribution, and more structural elements that participated in load redistribution. Furthermore, despite studies on progressive collapse under gravity loads, the dual system with X braces showed better progressive collapse performance (more resistance, residual reserve strength ratio and ductility) under seismic loads than the model with inverted V braces.

This paper presents an improved MAGNETIC CHARGED system search (IMCSS) and open application programming interface (OAPI) for optimization of double layer barrel vaults. In IMCSS algorithm, MAGNETIC CHARGED system search (MCSS) and an improved scheme of harmony search (IHS) are utilized and some of the most important parameters in the convergence rate of HS scheme are improved to achieve a good convergence and good solutions especially in final iterations. The OAPI is also utilized for the process of structural analysis, to link the analysis software with the IMCSS algorithm through the programming language. The results demonstrate the efficiency of OAPI as a powerful interface tool for analysis of large-scale structures such as double layer barrel vaults and also the robustness of the IMCSS as an optimization algorithm in fast convergence and achieving the optimal results.

Tumor detection and isolation in MAGNETIC resonance imaging (MRI) is a significant consideration, but when done manually by people, it is very time consuming and may not be accurate. Also, the appearance of the tumor tissue varies from patient to patient, and there are similarities between the tumor and the natural tissue of the brain. In this paper, we have tried to provide an automated method for diagnosing and displaying brain tumors in MRI images. Images of patients with glioblastoma were used after applying pre-processing and removing areas that have no useful information (such as eyes, scalp, etc.). We used a bounding box algorithm, to create a projection for to determining the initial range of the tumor in the next step, an artificial bee colony algorithm, to determine an initial point of the tumor area and then the Grow cut algorithm for, the exact boundary of the tumor area. Our method is automatic and extensively independent of the operator. comparison between results of 12 patients in our method with other similar methods indicate a high accuracy of the proposed method (about 98%) in comparison s.

The results confirm the efficiency of OAPI as a powerful interface tool in the analysis process of barrel vault structures and also the ability of IMCSS algorithm in fast convergence and achieving optimal results.

Finite element and Monte Carlo are two basic and useful methods in numerous modeling and simulation codes. CHARGED particles transport in electric and MAGNETIC fields based on these methods is the feasible manipulation of some software. There are, however few codes that have the ability of explaining the secondary radiation transport resulting from the movement of the CHARGED particles in a MAGNETIC field. FLUKA, for example, is known to be one of them. In this paper, a modeling and the simulation process using the FLUKA code for the survey of the synchrotron radiation of the electron are presented. The results found to be in agreement with those predicted by the known theoretical approach. The analysis of the synchrotron radiation of the output photon beam and the beam energy reduction are the basic results of the present work. For this investigation a specific field card MAGFLD and a USRBIN card have been applied.

The Future Circular Collider (FCC-ee), with its clean experimental environment, high energy, and luminosity, offers a unique opportunity for the precise study of the properties and interactions of top quarks. In this study, we have investigated the potential sensitivity of the FCC-ee to flavor-changing neutral current (FCNC) processes involving top quarks using an effective Lagrangian approach. To this end, the production of top quarks in electron-positron collisions at center-of-mass energies of 240 GeV and 365 GeV has been simulated, considering the full hadronic decay of the W boson resulting from the top quark decay. The results of the analyses show that by combining these center-of-mass energies and considering integrated luminosities of 5 ab⁻¹ and 1.5 ab⁻¹, an FCNC sensitivity on the order of 10⁻⁵ can be achieved. These findings highlight the significant potential of the FCC-ee for discovering and precisely studying FCNC processes, which could contribute to a better understanding of physics beyond the Standard Model.

Facilities built in areas affected by earthquake activity, such as tunnels, which have always been an integral part of human life, must withstand both dynamic and static loading. It has led to the need for practical studies on the effects of earthquakes on underground structures and the factors affecting their destruction. For this purpose, in this research, at first different patterns of tunnel’s excavation were investigated and by using Plaxis 2D software and based on Tabas earthquake in Iran, sensitivity analysis on geotechnical parameters of the soil surrounding tunnel such as cohesion, friction angle, unit weight and modulus of elasticity was carried out, and the parameters whose changes have the greatest and least effects on the bending MOMENT changes on the tunnel lining are introduced. The results show that tunnel excavation patterns significantly affect the bending MOMENT, axial forces, displacements, and surface settlement of the tunnel. Often, by dividing tunnel excavation area to small parts, the values of bending MOMENT, axial forces, displacements, and surface settlement of the tunnel decreases in static analysis. Also, outputs of sensitivity analysis on geotechnical parameters of the soil surrounding tunnel showed that modulus of elasticity of the soil surrounding tunnel has the most effect and cohesion changes have the least effect on bending MOMENT induced on tunnel lining..
