title: SPA-IAHP-CRITIC

description: To enhance Expressway's response to sudden accidents and improve maintenance resilience, this paper introduces safety resilience theory into high-speed section maintenance safety management. Considering highway features and based on resilience theory's five characteristics, key factors for high-speed maintenance safety resilience are identified using Word Frequency Analysis (WFA). The nonlinear mapping between system classification and highway characteristics is pivotal. Subjective and objective weights of maintenance safety resilience indices are weighted using the Interval Analytic Hierarchy Process Critical (IAHP-CRITICAL) method and Minimum Information Identification Principle, addressing traditional IAHP's fuzziness. The Improved Dung Beetle Algorithm Extreme Learning Machine (DBO-ELM) is employed for comprehensive evaluation. The WFA-CRITICAL-IAHP-DBO-ELM model is applied to a Chang-Zhang Expressway section.

title: Robustness Optimization for Compact Free-electron Laser Driven by Laser Wakefield Accelerators
title: Robustness Optimization for Compact Free-electron Laser Driven by Laser Wakefield Accelerators

description: We present a conceptual design for LWFA-driven FELs with enhanced robustness and reliability. By employing Bayesian optimization techniques, the beamline was optimized to achieve sufficient tolerance against these fluctuations under actual experimental conditions. Start-to-end simulations revealed that this systematic optimization significantly reduces the system's sensitivity to parametric variations. With the optimized configurations, the radiation energy can be maintained above 1 μJ at a wavelength of approximately 25 nm, even when accounting for twice the root-mean-square (RMS) ranges of these inherent jitters.

title: Prolonged Water-Body Types Dataset of Urban Agglomeration in Central China(1990-2021)

description: Data and knowledge of spatial-temporal dynamics of multiple types of water body are significant for water resources management but remain very limited. Using the Landsat satellite data and weakly supervised deep learning techniques for long term mapping, we report annual maps of multiple types of inland water bodies on urban agglomeration scale in the middle reaches of the Yangtze River(MRYR) during 1990–2021 at 30m spatial resolution. Accuracy assessment from 14000 validation points in seven years indicates an overall accuracy of 94.50%. Quantitative and qualitative comparison with other water related mapping products further demonstrates the superiority on long time span, refined classification system, and the high precision. The Water-MRYR could support the government and the public in the challenging water resources management and wetland conservation.

title: A high-resolution satellite-based solar-induced chlorophyll fluorescence dataset for China from 2000 to 2022

description: Solar-induced chlorophyll fluorescence (SIF) serves as a valuable proxy for photosynthesis. The TROPOspheric Monitoring Instrument (TROPOMI) aboard the Copernicus Sentinel-5P mission offers nearly global coverage with a fine spectral resolution for reliable SIF retrieval. However, the present satellite-derived SIF datasets are accessible only at coarse spatial resolutions, constraining its applications at fine scales. Here, we utilized a weighted stacking algorithm to generate a high spatial resolution SIF dataset (500 m, 8-day) in China (HCSIF) from 2000 to 2022 from the TROPOMI with a spatial resolution at a nadir of 3.5 km by 5.6–7 km. Our algorithm demonstrated high accuracy on validation datasets (R2 = 0.87, RMSE = 0.057 mW/m2/nm/sr). The HCSIF dataset was evaluated against OCO-2 SIF, tower-based measurements of SIF, and gross primary productivity (GPP) from flux towers. Our dataset can potentially advance the understanding of fine-scale terrestrial ecological processes, allowing for monitoring of ecosystem biodiversity and precise assessment of crop health, productivity, and stress levels in the long term. The Scale factor is 0.0001.

title: The Preparation of Ni-Cr Composite Coatings on Tungsten by Molten Salt Thermal Diffusion Method
title: 熔盐热扩散法在钨上制备镍铬复合涂层

description: Tungsten is a commonly used shielding material in Sr-90 Radioisotope thermoelectric generators; however, its resistance to high-temperature oxidation is relatively poor. This study aims to enhance the oxidation resistance of tungsten in high-temperature conditions. This study prepared a nickel-chromium composite coating on tungsten using the molten salt thermal diffusion method. The coatings produced at different molten salt temperatures were characterized using scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffraction. Additionally, cyclic oxidation tests and isothermal oxidation tests were conducted to evaluate the oxidation resistance and spallation resistance of the coatings. The adhesion strength between the coatings and the substrate was also assessed using the indentation method.The results indicate that the primary phase composition of the coatings is γ-(Ni,Cr). When the molten salt temperature is 950 ℃, the coating surface is blocky. The impurity P element in it gradually disappears, and the prepared nickel-chromium coating is more pure, with good oxidation resistance and anti-spallation properties. The study reveals that a dense layer of Cr2O3 formed on the surface of the oxidized sample. Furthermore, this sample demonstrated the highest adhesion, and the coating exhibited a fine crystalline structure. Therefore, a temperature of 950 ℃ is optimal for preparing nickel-chromium coatings using the molten salt diffusion technique.
