The Water Cherenkov Detector Array (WCDA) is one of the components of Large High Altitude Air Shower Observatory (LHAASO) and can monitor any sources over two-thirds of the sky for up to 7 h per day with >98 per cent duty cycle. In this work, we report the detection of two outbursts of the Fanaroff–Riley I radio galaxy NGC 1275 that were detected by LHAASO-WCDA between 2022 November and 2023 January with statistical significance of 5.2σand 8.3σ⁠. The observed spectral energy distribution in the range from 500 GeV to 3 TeV is fitted by a power law with the best-fitting spectral index ofα=−3.37±0.52and−3.35±0.29⁠, respectively. The outburst flux above 0.5 TeV was (⁠4.55±4.21)×10−11cm−2s−1and (⁠3.45±1.78)×10−11cm−2s−1⁠, corresponding to 60 per cent and 45 per cent of Crab Nebula flux, respectively. Variation analysis reveals the variability time-scale of days at the TeV energy band. A simple test by one-zone synchrotron self-Compton model reproduces the data in the gamma-ray band well.

Remaining useful life (RUL) prediction for electric vehicle battery (EV battery) is of great significance for the early replacement and regular maintenance of batteries with potential safety hazards in driving conditions. This paper proposes a novel method based on light gradient boosting machine (LightGBM) to predict the RUL of the battery under driving conditions. LightGBM uses the histogram optimization strategy to reduce the number of traversal of the data sample set and improve the robustness of the method;the depth-first splitting (leaf-wise) strategy reduces the risk of overfitting;the gradient-based one-sided sampling strategy (GOSS), reduce the data dimension;use the exclusive feature bundling strategy (EFB) to reduce the feature dimension. However, the LightGBM method has the difficulty of parameter setting. Therefore, this paper uses Hyperopt based on distributed asynchronous algorithm configuration/hyperparameter optimization to optimize its complicated hyperparameters. Subsequently, the method was applied to the prediction of battery RUL under simulated driving conditions. Based on the comparative cases, the results show that this method can guarantee the rapidity, accuracy and robustness of RUL prediction under the condition of low memory usage. © 2020 IEEE.

With the development of marine transport and expansion of the port scale, the port has become the energy intensive area and may evoke the pollution of surrounding environment. This paper studies the large port energy systems including integrated renewable energy, energy storage devices, plugged-in electric vehicles and shore to ship power supply. Based on the knowledge of multi-agent systems and distributed optimization, an innovation energy management solution for large ports is proposed, which considers energy entities with different energy forms. This method can not only ensure the balance of supply and demand(including power, heat and gas), but also optimize the energy allocation of ports and improve the energy utilization efficiency. Finally, simulation results illustrate the effectiveness of the proposed large port energy management solution based on distributed optimization with multi-agent systems.

We uncover the solution space of a five dimensional geometry which we deem it as the direct counterpart of the Bianchi Type V cosmological model. We kinematically reduce the scale factor matrix and then, with an appropriate scaling and choice of time, we cast the spatial equations into a simple "Kasner" like form;thus revealing linear integrals of motion. Their number is enough so that, along with the quadratic constraint, it suffices to scan the entire space of solutions. The latter is revealed to be quite rich, containing cosmological solutions, some of which admit dimensional reduction asymptotically to four dimensions, Kundt spacetimes with vanishing type I (polynomial) curvature scalars and solutions describing periodic universes which behave like cosmological time crystals. © 2024, The Authors.

Atomic-scale investigation of dissolution, accumulation, and diffusion behaviors of Xe in U 3 Si 2 using first-principles calculations

引用

Journal of Alloys and Compounds 2025年 1036卷

作者： Xianyun Feng Liuhai Gong Xianli Ren Rongjian Pan Wen He Jiaxuan Si Tianyuan Xin Mingpan Wan Yilong Liang Guigui Peng College of Materials Science and Metallurgical Engineering Guizhou University Guiyang 550025 China Guizhou Key Laboratory for Mechanical Behavior and Microstructure of Materials Guiyang 550025 China National & Local Joint Engineering Laboratory for High-performance Metal Structure Material and Advanced Manufacturing Technology Guiyang 550025 China The First Sub-Institute Nuclear Power Institute of China Chengdu 610005 China State Key Laboratory of Nuclear Reactor Technology Nuclear Power Institute of China Chengdu 610041 China

U 3 Si 2 is a promising accident-tolerant fuel (ATF) candidate due to its high thermal conductivity, high uranium density, and resistance to fission gas swelling. However, the behavior of xenon (Xe), a dominant fission gas product in U 3 Si 2 fuel, remains not fully understood. Using first-principles calculations, this study systematically investigates the dissolution, accumulation, and diffusion of Xe in U 3 Si 2 . Our results show that Xe has very low solubility in interstitial sites due to steric constraints and preferentially occupies vacancy defects, which provide larger space. While monovacancies have limited capacity to retain Xe, larger vacancy clusters facilitate Xe accumulation through favorable binding interactions. Diffusion analysis reveals marked anisotropy in Xe behavior, with interstitial migration barriers much higher than those for pathways mediated by vacancies. This indicates severely restricted Xe mobility in defect-free lattices. These findings explain the experimentally observed suppression of gaseous swelling: Xe bubble formation and growth in U 3 Si 2 depend on pre-existing defects rather than spontaneous nucleation. This study provides critical atomic-scale insights into Xe behaviors, supporting the potential of U 3 Si 2 as an advanced nuclear fuel material.

X_1(2900) as a D_1 K molecule

arXiv

arXiv 2021年

作者： Chen, Hao Qi, Hong-Rong Zheng, Han-Qing Department of Physics State Key Laboratory of Nuclear Physics and Technology Peking University Beijing100871 China Department of Engineering Physics Tsinghua University Beijing100084 China College of Physics Sichuan University Sichuan Chengdu610065 China

The analyses of the LHCb data on X(2900) in the D−K+ spectrum are performed. Both dynamically generated and explicitly introduced X1(2900) are considered. The results show that both these two approaches support the interpretation of X1(2900) as a D¯1K molecular state, with JP = 1− and an iso-singlet interpretation is much more favorable. The effect of triangle singularity on the production of X1(2900) is also discussed, and it is found that it cannot be interpreted as a pure triangle cusp. © 2021, CC BY.
