摘要： The magnitude of El Niño determines the level of its global impact. Yet, how well our state-of-the-art models simulate this key aspect of El Niño is not well documented. Previous studies tend to ignore ENSO asymmetry and equate the variance of ENSO to the magnitude of El Niño. Moreover, previous evaluations are more focused on the surface manifestation of El Niño. Here, we quantify the magnitudes of El Niño and La Niña separately, both at the surface and subsurface levels. At the surface, we find that while the magnitude of La Niña events in most models is generally stronger than observed, the magnitude of El Niño is more diverse to observations. In fact, in many models, El Niño is weaker than observed. This bias in the magnitude of El Niño is more pronounced in the subsurface. We attribute this weakness in the subsurface to the generally weaker coupling strength and the apparent stronger ENSO at the surface to a lack of sufficiently strong negative feedback from the surface heat flux in the models. When normalized by the variance of ENSO, the lack of exceptionally strong El Niño events in the models is more common and pronounced. The consequences of a generally weaker El Niño in the models are discussed.

摘要： 贫困问题是一个世界性难题，如何鼓励公众参与贫困救助对减少收入差距和实现共同富裕具有重要意义。本研究主要聚焦于通过贫困地理信息的呈现，即贫困是区域性的("地方穷")还是非区域性的("人穷")，以考察这一区域性贫困信息的操纵是否以及如何影响人们的贫困救助意愿和行为。通过4个实验，结果发现：相对于非区域性贫困信息组，区域性贫困信息组被试有更多的贫困救助意愿和行为(实验1~4)，且这主要是由于区域性贫困信息增加了被试的贫困外归因倾向(实验2~4)。本研究创新性地操控了贫困的地理信息，并通过实证揭示了它对公众贫困归因和救助行为的因果影响路径，具有重要的理论与实践价值。

摘要： We propose a distribution-free method for testing symmetry of distribution with copula entropy based two-sample test. The test statistic is defined as the statistic of two-sample test on symmetric transformation of distribution and its nonparametric estimation method is proposed. Three simulation experiments with beta distribution, asymmetric Laplace distribution, and bimodal normal distribution are conducted to verify the effectiveness of the proposed method and to compare it with the existing methods in the field. Experimental results show that the proposed method can measure the symmetry of the simulated distributions effectively and performs best among others.

摘要： 随着我国60岁及以上人口突破2.9亿，智慧养老作为银发经济的重要组成部分，面临”政策热、市场冷、技术空转”的现实困境。为探究多主体协同机制对智慧养老系统演化的影响，本文构建了政府、企业、平台与老年人四方演化博弈模型，融合系统动力学方法，探讨多主体策略博弈对银发经济系统演化的影响。模型以收益-成本函数与复制动态方程为基础，设定政府补贴强度、企业定价策略、平台数据开放度与老年人接纳意愿等关键变量，量化行为演化机制，并利用Jacobian矩阵分析策略稳定性，识别策略临界点与系统稳定性条件。基于Vensim平台，本文设计六类典型情景，模拟不同补贴、定价与开放策略组合下的系统演化过程。仿真结果表明，平台开放与老年人接纳构成系统协同演化的关键反馈路径；企业行为受平台激励和用户反馈联动影响，政府补贴效果则依赖于与市场响应之间的策略匹配度。在老年人不接纳情景下，系统演化出现策略漂移与非均衡态，反映出老年群体博弈决策在系统稳定性中的核心作用。基于上述发现，本文提出“三链协同机制”与“策略响应指标体系”，为智慧养老多元主体策略优化与银发经济高质量发展提供定量依据与政策参考。

摘要： This study focuses on the Pellet-Cladding Mechanical Interaction (PCI) behavior of silicon carbide fiber-reinforced silicon carbide composite (SiCf/SiC) cladding as an Accident-Tolerant Fuel (ATF) material. A specialized mandrel expansion test apparatus was developed to systematically investigate its failure characteristics under ambient and elevated temperatures (up to 920°C) and varied loading rates (0.5–1 mm/min). The experimental setup integrated Digital Image Correlation (DIC) and strain gauge systems to quantify stress-strain responses and critical failure parameters. Results demonstrated that elevated temperatures significantly degraded the load-bearing capacity of SiCf/SiC cladding, with average failure loads decreasing by 36.7% and failure strains reducing by 9.8%. Increased loading rates exacerbated non-uniform plastic deformation, leading to approximately 30% lower failure loads under room-temperature conditions. Furthermore, the failure process of SiCf/SiC cladding exhibited five distinct stages, with Stage IV (plunger-induced radial compression triggering cladding rupture) identified as the critical failure phase. This research provides essential experimental data for evaluating PCI performance of SiCf/SiC composite cladding, elucidates its high-temperature mechanical degradation mechanisms, and offers theoretical insights for optimizing nuclear fuel element design.

摘要： Accelerator-driven System (ADS) is widely regarded as the most effective transmutation solution of nuclear waste. The Monte Carlo transport simulation of full-energy-range particles, which are involved in both the spallation target and the sub-critical blanket, forms the foundation of ADS simulation studies. Based on the Monte Carlo simulation programs OpenMC and GMT, a program named MATS has been developed, which integrates reactor physics analysis and high-energy particle simulation capabilities for studying the ADS target-reactor system. The physical calculation functions of the program rely on an electromagnetic interaction module, a hadronic interaction module, a high-energy cross-section module, traditional reactor-oriented calculation functions and the nuclear data library. This equips MATS with the capability to simulate the transport processes of particles in a wide-energy range, which is essential for R&D of ADS because that there will be an underestimation of neutron fluence and heat density at the level of more than 10% when the neutrons above 20 MeV can not be transported. The benchmark calculations show that MATS can be used to perform ADS physical studies with reasonable deviations which are dominated by the spallation models. The development background of the program, the transport framework and functional modules, the details of the benchmark calculations and the further development plans are introduced.

摘要： Proton radiotherapy (RT) exhibits superior dosimetry benefits compared to conventional photon RT, primarily due to its capability to concentrate the therapeutic dose within a defined depth of the tumor volume. The production of secondary charged particles during proton irradiation results in a limited distribution close to the target volume. However, secondary neutrons exhibit a notable penetration capacity and higher relative biological effectiveness, accompanied by an increased risk of secondary tumors, particularly in pediatric patients. Monte Carlo toolkit, such as TOPAS, was widely used for dose evaluation. However, the lack of nuclear data for neutrons with kinematic energies exceeding 20 MeV, secondary particles resulting from the interaction of high-energy protons with tissues, necessitates improvements in simulation accuracy. Present study investigated the secondary neutron distribution during proton RT through a combination of TOPAS simulations and experimental measurements. The experiment was performed based on the IBA proton Proteus PLUS system with a gantry. A liquid scintillation detector (EJ301) with a diameter of 12.70 cm was utilized to measure secondary fast neutrons. Additionally, a wide-energy range neutron dosimeter was employed to measure the ambient dose equivalent of secondary neutrons, validating the simulation accuracy with favorable agreement. The Maximum Likelihood Expectation-Maximization (MLEM) inversion algorithm was used within TOPAS, the secondary neutron energy spectra were obtained with a distance of 50 cm from the isocenter and scattering angles of 0$^\circ$ and 135$^\circ$. Present study indicated that the simulated fast neutron spectra agree with the measurement-derived distribution. It's shown that the neutron ambient dose equivalent with a distance of 50 cm from the isocenter ranges from 0.19 to 18.6 mSv/Gy.

摘要： Accurate UAV positioning is vital for swarm cooperation. However, this remains challenging in situations where GNSS and other external infrastructures are unavailable. To address the challenge, we propose to only use the onboard MIMU, monocular camera and UWB device to construct a distributed and anchor-free cooperative localization system by tightly fusing the measurements. As the onboard UWB measurements in dynamic motion conditions is noisy and discontinuous, we propose an adaptive adjustment method based on chi-square detection to effectively filter out inconsistent and false ranging information. Moreover, we introduce the pose-only theory to model the visual measurement, which improves the efficiency and accuracy for visual-inertial processing. Then a sliding window extend Kalman filter was constructed to fuse all the measurements in a tightly way, which is capable to work under UWB or visual deprived conditions. To overcome the state consistency challenge inherent in the distributed cooperative structure, we propose to not only model the UWB noisy uncertainty but also the neighbor agent’s position uncertainty into the measurement model. To validate the effectiveness of proposed our methods, we have established both simulation and hardware test platforms. The proposed method is compared with state-of-the-art (SOTA) UAV localization approaches designed for GNSS-challenged environments. Extensive experiments demonstrate that our algorithm achieves superior positioning accuracy and higher computational efficiency. Moreover, even when vision loss causes other methods to fail, our proposed method continues to operate effectively.

摘要： The advancement and deployment of lead-cooled fast reactors (LFRs) are significantly hindered by the corrosive nature of lead-bismuth eutectic (LBE) coolant, which adversely affects internal components, including the main coolant pump(MCP). This corrosion can lead to structural failures, posing serious risks to reactor operational safety. In this study, a computational fluid dynamics (CFD) based mathematical model of an axial flow pump in a lead-bismuth reactor was developed and validated using experimental data. Numerical simulations of the MCP were conducted under various operational conditions using the SST k-ω turbulence model. The results revealed that the blade surface skin friction coefficient (Cf) reaches its maximum at the blade inlet edge. Under standard operating conditions, the peak Cf at the blade leading edge is minimized; however, When under the operating conditions of 0.8Q0 and 1.2Q0, the peak value of Cf increased by approximately 36.3% and 72.7% respectively compared to the rated operating conditions. This will result in the MCP being unable to operate stably under eccentric working conditions.deviations from these conditions cause a rapid increase in Cf at this location. Additionally, Cf at the blade leading edge exhibited a positive correlation with the velocity gradient of the LBE. This study provides valuable insights for optimizing the hydraulic design of MCP in LFRs and for further investigation into the structural aspects of reactor flow channels.

摘要： The energy response of an imaging detector based on a monolithic crystal is highly dependent on the position of the gamma ray interaction, which leads to a spectral drift of the imaging detector, known as the spectral drift related to incident position. It deteriorates the energy resolution of the detector and affects the selection of the energy window for imaging, resulting in artefacts in the reconstructed image. Thus, a energy response correction method is proposed to improve the positional consistency of the detector energy response. In both simulation and physical experiments, the method improved the full-energy peak consistency of the monolithic crystal detector, which results in improved energy resolution of the detector, more accurate selection of the energy window, and imaging quality. Especially, in physical experiments, the method converges the peak sites of 365keV energy at each location, which reduced the half-height width of characteristic peak (@365 keV) from 53 to 38 channels, improved the energy resolution by 28.3%, transformed the incomplete mask projection into a complete mask projection, and the signal-to-noise ratio increased from 2.38 to 5.37.

摘要： This study experimentally investigated the heat transfer performance of a novel shell-and-tube fluoride Salt to Salt Heat Exchanger (SSHX) featuring baffles with integrated drainage ports, designed to mitigate salt freeze blockage risks during shutdown in Molten Salt Reactors (MSRs). Experiments were conducted in a Scaled Simulation Fluoride Salt-cooled Reactor (SF0) test facility. A new empirical correlation for tube-side heat transfer was proposed as Nu=0.0246Re0.8Pr0.267 (valid for Re=9000~15000 and Pr=8~12), demonstrating excellent agreement with experimental data within a maximum deviation of 5%. Comparative analysis revealed the modified Dittus-Boelter equation is still a suitable choice for predicting fluoride salt convective heat transfer behavior in tubular geometries, outperforming the Gnielinski and Sieder-Tate models, which overpredicted data by 17-25%. For shell-side heat transfer, applying a 31% enhancement factor (ε=1.31) to the Kern correlation aligns predictions with experimental results within an error range of -6.0% to 7.0%. These findings address a critical engineering challenge in SSHXs while preserving thermal efficiency, offering essential experimental data and valuable insights for the design of fluoride SSHXs in MSRs.

摘要： In this study, the transient response and dispersion characteristics in a traveling-wave accelerator are analyzed via an equivalent circuit method. A SLAC-like constant-gradient traveling-wave Linac is used as an example to construct a cascaded equivalent circuit model. Different transient response solution methods, including dynamic circuit simulation, iterative solving of circuit differential equations, and quasi-steady-state solutions of differential equations, are compared, and consistent results are obtained. The influence of dispersion on the transient response is analyzed from the perspectives of envelope oscillations and the transient process. A compensation scheme for dispersion is proposed using the multi-objective genetic algorithm NSGA-II. The beam load is also compensated by adding a ramp to the initial input pulse. The results show that the equivalent circuit model can effectively analyze the transient response in the Linac, and the proposed compensation scheme can mitigate the dispersion effects. This research can provide guidance for the design and tuning of the RF feedforward system.

摘要： The stability of Diaphragm Walls (DWs) in deep foundation pits is a critical concern in urban construction, where complex excavation activities can induce significant structural deformations. This study aims to evaluate the impact of different excavation sequences on the displacement behavior of DWs to improve excavation safety and structural performance. A series of numerical simulations were conducted using four distinct excavation scenarios to analyze the lateral deformation patterns of DW1, DW2 and DW3. Based on the observed results, Case 3 demonstrated the most favorable performance, with wall displacements remaining within allowable limits, indicating improved structural stability. To further assess localized structural responses, the displacement behavior of DW4, DW5, DW6 and DW7 was also analyzed under Case 3. The results showed that all walls experienced inward displacement within allowable limits. The findings highlight that displacement magnitudes are influenced by factors such as wall position, excavation-induced stress redistribution, and soil-structure interaction. DW2, serving as a shared wall between adjacent pits, exhibited higher sensitivity to excavation activities. This study underscores the importance of optimized excavation sequencing and structural interaction analysis in mitigating wall displacements and enhancing the stability of deep foundation pits in complex urban environments.
