    Anomalous Magnetic Dipole Moment (g2)μ(g-2)\mu in 3-3-1 Model with Inverse Seesaw Neutrinos

    We will show that the recent experimental value of the anomalous magnetic moment (AMM) of the charged lepton m , denoted as amu(g2)μ/2a_mu (g-2)\mu/2, can be explained successfully in a 3-3-1 model with right handed neutrino adding new heavy SU(3)LSU (3)_L neutrinos singlets. Allowed regions satisfying the recent AMM data are illustrated numerically

    From Negative Aspects and Black Aspects of Vietnam Education to Lessons for Social Sciences Students

    Get PDF
    In our research, we level strong criticism at the State Professor Council in Vietnam, using the case of Tran Van Tho and other members as a representative illustration of their efforts to impede or restrict the growth of the nation's scientific community. We also do not place enough importance on the publication of bogus news online by various Vietnam publications (Thanhnien.vn and Tuoitre.vn), despite the fact that it may lead to confusion, as well as problems and concern in the community. In addition, we oppose the excessive tuition fees and other expenses that have been imposed by Banking University HCM city Vietnam and other institutions in HCM city in recent years, which have caused difficulties for families, parents, students, and society as a whole. In addition, we use these problematic aspects of the education system in Vietnam as a case study to instruct students majoring in social sciences. After that, the authors apply a strategy based on the laws of Malaysia in order to solve the problem of fake news published in the newspapers tuoi tre and thanh nien in Vietnam throughout the period 2015-2022. After the case discussion that was offered earlier, the authors assess the opinions of President Ho Chi Minh on publishing activities for the purpose of better teaching pupils. This is not the least of the authors' contributions

    Edge Effects of Truncated Dirac Solitons in Binary Waveguide Arrays

    Get PDF
    We investigate the edge effects of the optical analogue of the quantum relativistic Dirac solitons in binary waveguide arrays with Kerr nonlinearity when one tail of the Dirac soliton is truncated. We show that if the outermost waveguide of the binary waveguide array hosts the intense component of the truncated Dirac soliton, then Dirac soliton will be repeatedly bent towards the binary waveguide array edge. In the contrast, if the outermost waveguide of the binary waveguide array hosts the weak component of the truncated Dirac soliton, then Dirac soliton will be pushed away from the binary waveguide array edge. To the best of our knowledge, these unique features have not been found in any other systems

    Delay factors in the construction of irrigation and hydropower projects in Vietnam

    Get PDF
    Irrigation and hydropower are among the most important sectors in the construction industry that propel the economic needs of a developing country like Vietnam. The construction of these projects often suffers from severe delays, leading to financial losses and other negative impacts on the economy. This paper aims to determine delay factors in the construction of these projects. Among many, 39 most important candidates of delay causes were identified from the literature review. Further surveys on project participants were conducted for the severity of these causes. An exploratory factor analysis was utilized to identify latent factors that cause delays in construction projects. The analysis result categorized a few groups of factors such as abnormal factors on the construction site (e.g., labor accidents, hydrology, water flow, extreme weather) and technical factors related to the construction contractor (e.g., unsuitable schedule, outdated construction technology, unprofessional workers) that have the greatest impact on the delay in construction of irrigation and hydropower projects in Vietnam. These findings contribute to the body of knowledge of project management and risk management, hence an improvement in the efficiency of the project sectors’ performance

    Teaching English vocabulary to young learners through total physical response method

    Get PDF
    This study attempts to investigate the effect of the Total Physical Response (TPR) Method on vocabulary retention and explore the young learners’ attitudes toward it. It involved sixty two English young learners (YLs) aging from 10 to 11. All of them were attending English classes at Viet Uc English Language Center (henceforth called VUC) in Bien Hoa City where the current study was conducted. Both quantitative and qualitative data was obtained through the three instruments, namely pre- and post-test and interview. Descriptive statistics was employed for data analysis. The results revealed that TPR had effect on the YLs’ vocabulary knowledge through an increase in their vocabulary retention after they underwent the treatment. Similarly, the findings of the study also revealed that the YLs had positive attitudes toward the use TPR in vocabulary teaching and learning. This study is expected to shed light to the implementation of teaching vocabulary methods in the VUC context and other similar contexts

    Lepton Flavor Violation in Economical 3-3-1 Model with Neutrino Singlets

    Get PDF
    Lepton flavor violating (LFV) decays of charged leptons μeγ\mu\rightarrow e\gamma  and SM-like Higgs boson hμτh\rightarrow \mu\tau are discussed in the framework of the  economical 3-3-1 model  adding three additional singlets neutrinos (E331XRX_R). We will show that the appearance of new neutrinos and charged Higgs bosons in this model can result in interesting regions of the parameter space, which satisfy  the recent experimental bound of Br(μeγ)Br(\mu\rightarrow e\gamma)  as well as give large Br(hμτ)O(107)Br(h\rightarrow \mu\tau)\geq \mathcal{O}(10^{-7}) . In these regions,  the charged Higgs boson mass lies within the range of 232-3 TeV. Our results show that the LFV decays are important channels to distinguish the E331XRX_R  and the original economical (E331) models, which predicts suppressed LFV decay rates
