The universality of the weak interactions can be tested in semileptonic b→c transitions,and in particular in the ratios R（D＊） ≡ Γ（B → D（＊）τν）/Γ（B → D＊lν）（where 1 = μ or e）.Due to the recent differences between the experimental measurements of these observables by Ba Bar,Belle and LHcb on the one hand and the standard Model predicted values on the other hand,we study the predicted ratios R（D＊）=Γ（B→D＊τ＋＂missing＂）/Γ（B→D（＊）lν）in scenarios with an additional sterile heavy neutrino of mass ～1 Ge ***,we evaluate the newly defined ratio R（0）≡Γ（B→τ＋＂missing＂）/Γ（B→μν） in such scenarios,in view of the future possibilities of measuring the quantity at Belle-Ⅱ.

We present a search strategy for both Dirac and Majorana sterile neutrinos from the purely leptonic decays of W^±→e^±e^±μ ν and μ^±^±e ν at the 14 TeV LHc. The discovery and exclusion limits for sterile neutrinos are shown using both the cut-and-count（cc） and Multi-Variate Analysis（MVA） methods. We also discriminate between Dirac and Majorana sterile neutrinos by exploiting a set of kinematic observables which differ between the Dirac and Majorana cases. We find that the MVA method, compared to the more common cc method, can greatly enhance the discovery and discrimination limits. Two benchmark points with sterile neutrino mass m N =20 GeV and 50 GeV are tested. For an integrated luminosity of 3000 fb^-1, sterile neutrinos can be found with 5σ significance if heavy-to-light neutrino mixings ｜U_（Ne）｜^2~｜U_（Nμ）｜^2~10^-6, while Majorana vs. Dirac discrimination can be reached if at least one of the mixings is of order 10^-5.

The mission of Korea superconducting Tokamak Advanced Research (KsTAR)project is to develop an advanced steady-state superconducting tokamak for establishing a scientificand technological basis for an attractive fusion reactor. Because one of the KsTAR mission is toachieve a steady-state operation, the use of superconducting coils is an obvious choice for themagnet system. The KsTAR superconducting magnet system consists of 16 Toroidal Field (TF) coils and14 Poloidal Field (PF) coils. Internally-cooled cable-In-conduit conductors (cIcc) are put into usein both the TF and PF coil systems. The TF coil system provides a field of 3.5 T at the plasmacenter and the PF coil system is able to provide a flux swing of 17 V-sec. The major achievement inKsTAR magnet-system development includes the development of cIcc, the development of a full-size TFmodel coil, the development of a coil system for background magnetic-field generation , theconstruction of a large-scale superconducting magnet and cIcc test facility. TF and PF coils are inthe stage of fabrication to pave the way for the scheduled completion of KsTAR by the end of 2006.

Amyotrophic lateral sclerosis(ALs)is a progressive neurodegenerative disorder characterized by the degeneration of motor neurons in the brain and spinal cord,leading to muscle weakness,paralysis,and ultimately death(cleveland and Rothstein,2001).Frontotemporal lobar degeneration(FTLD)is a neurodegenerative disease affecting the frontal and temporal lobes of the brain,leading to changes in behavior,personality,and language(Van Langenhove et al.,2012).Both ALs and FTLD are classified as proteinopathies in which abnormal protein aggregation and accumulation in neurons contribute to the disease *** in sarcoma(FUs)is a DNA/RNA-binding protein involved in various cellular processes,including transcriptional regulation,RNA splicing,and DNA *** in the FUs gene have been linked to familial ALs,highlighting the importance of FUs in the disease pathogenesis(Vance et al.,2009).In ALs and FTLD,aberrant post-translational modifications(PTMs)of FUs,such as phosphorylation,acetylation,and methylation,have been implicated in the promotion of FUs aggregation and neurotoxicity(choi et al.,2023).Therefore,understanding the regulatory mechanisms of FUs PTMs is crucial for developing targeted therapies against these diseases.
