摘要：As a joint-optimization problem which simultaneously fulfills two different but correlated embedding tasks （i.e., entity embedding and relation embedding）, knowledge embedding problem is solved in a joint embedding scheme. In this embedding scheme, we design a joint compatibility scoring function to quantitatively evaluate the relational facts with respect to entities and relations, and further incorporate the scoring function into the maxmargin structure learning process that explicitly learns the embedding vectors of entities and relations using the context information of the knowledge base. By optimizing the joint problem, our design is capable of effectively capturing the intrinsic topological structures in the learned embedding spaces. Experimental results demonstrate the effectiveness of our embedding scheme in characterizing the semantic correlations among different relation units, and in relation prediction for knowledge inference.

摘要：粉尘是港口散货港区煤炭堆场主要大气污染物,防风网抑尘效率通常在50%~70%。研究采用数值模拟方法,建立南港东港区煤堆场几何模型、风速场等数值模型,选定典型环境情景,借助Fluent 6.3.26软件,对防风网抑尘工况参数进行模拟优化。结果表明,堆网间距为1倍堆高、孔隙率为0.4、网高为1.2倍堆高时,防风网抑尘效率可达90%。若将抑尘效率从50%提高至90%,东港区年粉尘排放量将减少0.62万吨,其贡献十分可观。

摘要：目的:设计抗铜绿假单胞菌的新型双功能(杀菌和中和内毒素)的杂合抗菌肽,并探究其杀菌特性。方法:拟以四肽GGGS-Linker偶联中和内毒素多肽和抗铜绿假单胞菌活性抗菌肽,构建新型双功能杂合抗菌肽,并对结构特征进行分析;测定其抗铜绿假单胞菌的活性和杀菌特点;进一步评价目标杂合肽对内毒素的中和作用和对兔红细胞的溶血性。结果:设计并获得具有高抗铜绿假单胞菌和中和内毒素双重功效的杂合抗菌肽LLM,其携带+8正电荷;LLM对铜绿假单胞菌*** CMCC10104和*** ATCC 9027的MIC分别为2、4μmol/L,MBC/MIC=1,其抗菌活性均优于母体肽;LLM能够快速杀菌,1 h处理能够杀灭99%以上的铜绿假单胞菌。LLM对内毒素呈现较强的中和作用,能够显著降低培养液中内毒素产生水平;LLM在高达115μmol/L(400μg/mL)时对兔红细胞没有表现出显著的溶血性。结论:LLM抗铜绿假单胞菌的MIC为2~4μmol/L,能够中和内毒素,可以快速杀菌,且浓度低于115μmol/L时未表现出显著溶血性。

摘要：To ameliorate the disadvantages of imaging system coupled with imaging fiber bundle, a method by adding square aperture microlens arrays at both entrance and exit ends of the imaging fiber bundle is proposed to increase the system's coupling efficiency. The expressions for solving the parameters of both ends' microlens units are deducted particularly. The microlens arrays used for an infrared imaging fiber bundle with the single fiber diameter of 100 μm and core diameter of 70 μm are designed by this method. The simulation results show that compared with the system without microlens arrays, the fill factor of the imaging fiber bundle coupled microlens arrays system is increased from 44.4% to more than 90%, and the coupling efficiency is doubled too. So the design method is correct, and the introduction of microlens arrays into imaging fiber bundle coupled system is feasible and superior.

摘要：在拟利用场地局部较浅风化岩层作基础持力层时,通过对比预应力管桩、钻孔灌注桩、复合地基等传统形式的优缺点,最终确定了静压管桩与静压植桩相结合的方案。静压植桩技术先利用旋挖桩机引孔至岩面或入岩一定深度,然后浇筑强度为C30水下细石混凝土,最后用静压桩机将管桩穿过自制垂直度控制装置,并压至设计压力值。通过在实际工程中的应用,验证了该技术的可行性、可靠性,其桩身垂直度、完整性、单桩竖向承载力均得到了良好控制;该技术与传统静压工艺的结合,降低了工程造价,缩短了施工工期,还减少了锤击植桩产生的噪声。
