To process the uncertainty of decision-making environment and the real-time during the tactical decision of UAV medium-range air combat, a hybrid tactical decision-making method based on rule sets and Fuzzy Bayesian network（FBN） was proposed. By studying the process of UAV air combat, the main factors that affect the tactical decision were analyzed. A corresponding FBN and expert system were built up. The hybrid system retained the advantage of expert system by the first call to it. In the mean time, the system could also process the uncertainty of decision-making environment by means of the FBN. Finally, through the air combat simulation, the correctness, realtime and effectiveness in an uncertain environment of the hybrid tactical decision-making method were verified.

目的从青少年人格及同伴环境相互作用的角度,探讨同伴关系与环境敏感性的交互作用对青春期女性心理健康发展的影响,以及其相互作用的理论模型。方法2022年9月至11月,在陕西省西安市4个城区6所中学(7~12年级)的120个班开展青少年心理健康的问卷调查,随机选取5640名年龄在14~17岁的中学生为研究对象,其中女性有3135名(占55.6%),在完成心理健康问题(抑郁焦虑情绪、外化行为、自杀倾向、睡眠质量和主观幸福感)的测试后,进行同伴关系与环境敏感性的评估,并对结果进行统计学分析。结果①青春期女性的环境敏感性、同伴关系、抑郁情绪、焦虑情绪、睡眠质量、自杀倾向和主观幸福感得分均明显高于青春期男性(t值分别为-7.504、-7.203、5.554、6.128、5.248、12.194、-2.864,P0.05)。③心理问题史在预测青春期女性主观幸福感、抑郁情绪和睡眠质量时,主效应均显著(b值分别为0.221、-0.361、-0.394,P<0.01);同伴关系及环境敏感性在预测青春期女性的主观幸福感、抑郁情绪、自杀倾向和睡眠质量时,主效应均显著(同伴关系:b值分别为0.283、-0.086、-0.431、-0.179,P<0.01,环境敏感性:b值分别为0.041、0.172、0.082、0.167,P<0.01);同伴关系与环境敏感性的交互作用均显著(b值分别为0.072、-0.074、-0.102、-0.093,P<0.05)。④同伴关系与环境敏感性对青春期女性主观幸福感、自杀倾向的交互作用符合差别易感性模型[主观幸福感:交互作用比例指标(PoI)=0.680,受影响比例指标(PA)=0.720;自杀倾向:PoI=0.250,PA=0.210],而同伴关系与环境敏感性对青春期女性抑郁情绪、睡眠质量的交互作用符合素质-压力模型(抑郁情绪:PoI=0.010,PA=0.008;睡眠质量:PoI=0.050,PA=0.030)。结论同伴关系与环境敏感性的交互作用对青春期女性主观幸福感及自杀倾向的影响支持差别易感性模型,而对抑郁情绪、睡眠质量的影响符合素质-压力模型,提示高环境敏感性女性更容易受到消极同伴关系的影响而表现出更多的心理问题,同时也更多获益于积极同伴环境的作用而促进健康发展。

Acta Metallurgica Sinica(English Letters) 2017年第10期30卷 957-964页

作者： Yan-Li Song Cheng Yu Xia Miao Xing-Hui Han dong-Sheng qian Xu Chen Hubei Key Laboratory of Advanced Technology of Automotive Parts Wuhan University of Technology Hubei Collaborative Innovation Center for Automotive Components Technology Wuhan University of Technology School of Materials Science and Engineering Wuhan University of Technology

This paper discusses the tribological performance of the bearing steel GCr15 treated by an alternating magnetic field. The wear test results showed that the average of wear mass losses decreased by nearly 80% after the magnetic treatment, compared to those before the magnetic treatment. The micro-hardness and microstructures（i.e., grain size,carbide morphology and dislocation distribution） before and after the magnetic treatment were experimentally investigated,and the mechanism of the tribological performance improvement of the bearing steel GCr15 due to the magnetic treatment was then revealed based on the above results.

Precisely designed protein-based nanodrugs, as a kind of colloidal drug system, have attracted significant attention in tumor therapy because of their refined drug loading ratio, controlled delivery efficacy and natural biocompatibility. However, most drugs are conjugated to the protein carriers randomly without specific binding sites. Moreover, such sites could easily be replaced by lipophilic molecules in the physiological environment and result in low delivery efficiency. With strong and specific binding locations especially comparatively narrow spatial binding sites and nonflexible structure, hemin (FePPIX)-free hemoglobin or apohemoglobin (apoHb), as a natural metalloporphyrin protein carrier, represents great potential in bioapplication. Therefore, we herein introduce a folate acid (FA) modified, zinc-substituted hemoglobin (ZnPHb-FA) as a naturally occurring protein matrix-based photosensitizer for cancer photodynamic therapy (PDT). Noncovalent inserted ZnPPIX molecules in apoHb possess an extremely stable property and significant recovered photoproperties with superior biocompatibility and phototoxicity, both in vitro and in vivo. This stability was verified by molecular docking analysis and calculation of binding constant, representing a total of five drug binding sites of apoHb for ZnPPIX molecules, four of which are energetically favorable (△G value of -11.9 kcal/mol), and one which is energetically acceptable (△G value of -9 kcal/mol). Folate acid modification has been shown to efficiently enhance the internalization and retention time of ZnPHb nanodrug. ZnPHb-FA is also an efficient depressor of hemin oxygenase-1 (HO-1), which could, in turn, lower the antioxidant ability of cancer cells by decreasing the production of biiirublin. Results in vitro and in vivo both indicated that the firmly combination of apoHb and ZnPPIX described here represents a novel and efficient protein nanodrug systems for cancer therapy.

A systematic framework of constructing surrogate model for slider track peeling strength prediction

引用

Science China Technological Sciences 2024年第10期67卷 3261-3274页

Peeling strength can comprehensively reflect slider track safety and is crucial in car seat safety assessments. Current methods for determining slider peeling strength are primarily physical testing and numerical simulation. However, these methods encounter the potential challenges of high costs and overlong time consumption which have not been adequately addressed. Therefore, the efficient and low-cost surrogate model emerges as a promising solution. Nevertheless, currently used surrogate models suffer from inefficiencies and complexity in data sampling, lack of robustness in local model predictions, and isolation between data sampling and model prediction. To overcome these challenges, this paper aims to set up a systematic framework for slider track peeling strength prediction, including sensitivity analysis, dataset sampling, and model prediction. Specifically, the interpretable linear regression is performed to identify the sensitivity of various geometric variables to peeling strength. Based on the variable sensitivity, a distance metric is constructed to measure the disparity of different variable groups. Then, the sparsity-targeted sampling(STS) is proposed to formulate a representative dataset. Finally, the sequentially selected local weighted linear regression(SLWLR) is designed to achieve accurate track peeling strength prediction. Additionally, a quantitative cost assessment of the supplementary dataset is proposed by utilizing the minimum adjacent sample distance as a mediator. Experimental results validate the efficacy of sequential selection and the weighting mechanism in enhancing localization ***, the proposed SLWLR method surpasses similar approaches and other common surrogate methods in terms of prediction performance and data quantity requirements, achieving an average absolute error of 3.3 kN in the simulated test dataset.

Sulphide melt evolution in upper mantle to upper crust magmas,Tongling, China

Geoscience Frontiers 2014年第2期5卷 237-248页

作者： Yilun Du Xinlong Qin Calvin G.Barnes Yi Cao qian dong Yangsong Du School of Earth Sciences and Resources China University of Geosciences (Beijing) Nonferrous Metals Geological Exploration Bureau of East China in Jiangsu Province Department of Geosciences Texas Technology University

Sulphide inclusions, which represent melts trapped in the minerals of magmatic rocks and xenoliths, provide important clues to the behaviour of immiscible sulphide liquids during the evolution of magmas and the formation of NieCueFe deposits. We describe sulphide inclusions from unique ultramafic clots within mafic xenoliths, from the mafic xenoliths themselves, and from the three silica-rich host plutons in Tongling, China. For the first time, we are able to propose a general framework model for the evolution of sulphide melts during the evolution of mafic to felsic magmas from the upper mantle to the upper crust. The model improves our understanding of the sulphide melt evolution in upper mantle to upper crust magmas, and provides insight into the formation of stratabound skarn-type FeeCu polymetallic deposits associated with felsic magmatism, thus promising to play an important role during prospecting for such deposits.

Facile fabrication of porous pure and Ag nanoparticle-doped poly(4-vinylpyridine) films at the liquid-liquid interfaces

引用

Chinese Chemical Letters 2011年第7期22卷 867-870页

作者： Zhi Bin Ren Jiang Liu Yu Ping Chen Meng Chen dong Jin qian Department of Chemistry Fudan University Shanghai 200433 China

We reported an interfacial self-assembly of regularly layered porous poly（4-vinylpyridine）（P4VP） films at the interfaces of water-chloroform or -dichloroethane. The porous diameters were in the range from hundred nanometers to several micrometers. It was revealed that formation of such kind of porous materials was solvent dependent. Moreover, cyclic Ag nanoparticles could be grown in the porous P4VP films to form Ag-P4VP nanohybrids under radiation.
