与社会主义和谐社会目标相适应的社会主义和谐文化,应该既具有传统文化根基,也符合现代社会要求。为了培育融传统智慧与现代文明于一体的社会主义和谐文化,我们在汲取传统的“和”观念的智慧的同时,要努力开掘与“和”的价值相联系的其他传统价值,要重视对这些传统价值作现代诠释,寻找在当前情况下支撑这些价值的制度安排和社会载体,尤其要用现代思维方法对“和而不同”的含义和要求作确切的分析。

合适的距离度量函数对于聚类结果有重要的影响。针对大规模高维数据集,使用增量式聚类算法进行距离度量的选择分析。SpFCM算法是将大规模数据集分成小样本进行增量分批聚类,可在有限的计算机内存中获得较好的聚类结果。在传统的SpFCM算法的基础上,使用不同的距离度量函数来衡量样本之间的相似性,以得出不同的距离度量对SpFCM算法的影响。在不同的大规模高维数据集中,使用欧氏距离、余弦距离、相关系数距离和扩展的杰卡德距离来计算距离。实验结果表明,后3个距离度量相对于欧氏距离可以很大程度地提高聚类效果,其中相关系数距离可以得到较好的结果,余弦距离和扩展的杰卡德距离效果比较一般。

This work reported a facile approach to surface oxygen vacancy(O_(v))-enriched urchin-like TiO_(2) microparticles(U-TiO_(2)),which were highly effective and durable in catalyzing selective nitrate reduction to ammonia(NOgRR),Specifically,the U-TiO_(2)delivered a mass activity of 1.15 min^(-1)mg^(-1)calyst.a low yield of toxic NO_(2)^(-)-N intermediate(≤0.4mg/L)and an exceptional high NH_(3)^(-)-N selectivity of 98.1%in treating 22.5 mg/L of NO_(3)^(-)-N under a potential of-0.60V vs.RHE,outperforming most of the reported oxidebased catalysts.When comparing the performance of U-TiO_(2)with that of the solid amorphous TiO_(2) counterpart(A-TiO_(2))that had close particle size but more O_(v) on surfaces,we identified that the O_(v) was the reactive sites,but rather than its content,the NO_(3)RR kinetics were primarily limited by the electron and mass transfer at U-TiO_(2)/water interfaces.Accordingly,the superior performance of U-TiO_(2)to A-TiO_(2)could be ascribed to the hierarchical urchin-like structure in U-TiO_(2).The in-situ DEMS test revealed that the NO_(3)RR on U-TiO_(2)followed a pathway of ^(*)NO_(3)^(-)→^(*)NO_(2)^(-)→^(*)NO→^(*)N→^(*)NH^(-)→^(*)NH_(2)→^(*)NH_(3).We also demonstrated that the U-TiO_(2) could keep its robust performance under a wide NO_(3)^(-)-N concentration range and in the presence of some co-existing ions(such as Ca^(2+),Cl^(-),Mg^(2+)).However,the presence of humic acid and CO_(3)^(2-) in water slowed down the NO_(3)RR on U-TiO_(2).This work provides a more fundamental insight into the O_(v)-driven NO_(3)RR process on TiO_(2),which should benefit for the development of eficient TiO_(2)-based catalvsts.

Glaciers in the eastern Pamir are important for water resources and the social and economic development of the region.In the last 50 years,these glaciers have shrunk and lost ice mass due to climate change.In order to understand recent glacier dynamics in the region,a new inventory was compiled from Landsat TM/ETM+ images acquired in2009,free of clouds and with minimal snow cover on the glacierized mountains.The first glacier inventory of the area was also updated by digitizing glacier outlines from topographical maps that had been modified and verified using aerial photographs.Total glacier area decreased by 10.8%±1.1%,mainly attributed to an increase in air temperature,although precipitation,glacier size and topographic features also combined to affect the general shrinkage of the glaciers.The 19.3–21.4 km^3 estimated glacier mass loss has contributed to an increase in river runoff and water resources.

基于最大散度差判别准则提出了一种模糊最大散度差准则,并根据模糊最大散度差准则提出一种聚类方法(fuzzy maximum scatter difference discriminant criterion based clustering algorithm,简称FMSDC).该方法通过迭代优化方法实现聚类的同时还可以实现特征降维.该方法首先在最大散度差判别准则中引入模糊概念;然后通过具体原则设定模糊最大散度差判别准则中的参数η,从而在一定程度上降低了由参数η引起的敏感性;最后分别根据模糊隶属度μik、最优鉴别矢量ω进行聚类和特征降维.实验结果表明,FMSDC方法不但具有基本的聚类功能,而且具有较好的鲁棒性和较强的特征降维能力.

基于最小类内散度支持向量机(MCSVMs)提出一种新的矩阵模式的最小类内散度支持向量机(MCSVMsmatrix).同时为了更好地解决非线性分类问题,将Mercer核函数引入到MCSVMsmatrix方法中,并提出基于矩阵模式的非线性支持向量机:Ker-MCSVMsmatrix.上述两种方法不但继承了MCSVMs的优点,而且由于将矩阵模式的类内散度矩阵引入到支持向量机中,从而在理论上可以较好地解决了MCSVMs方法在处理小样本高维数据集时类内散度矩阵奇异性问题,同时降低了求解类内散度矩阵及其逆矩阵和权重矢量的时间、空间复杂度.因此,在一定程度上提高了分类精度.实验结果也表明MCSVMsmatrix、Ker-MCSVMsmatrix具有上述优势.

BACKGROUND Embolic superior mesenteric artery(SMA) occlusion is associated with high mortality rates. Delayed treatment often leads to serious consequences, including intestinal necrosis, resection, and even patient death. Endovascular repair is being introduced, which can improve clinical symptoms and prognosis and decrease the incidence of exploratory laparotomy. Many reports have described successful endovascular revascularization of embolic SMA occlusion. However,most of those reports are case reports, and there are few reports on Chinese patients. In this paper, we describe the technical and clinical outcomes of aspiration therapy using a guiding catheter and long sheath technique which facilitates the endovascular repair procedure.AIM To evaluate the complications, feasibility, effectiveness, and safety of endovascular treatment for the acute embolic occlusion of the SMA.METHODS This retrospective study reviewed eight patients(six males and two females)from August 2013 to October 2018 at Xuanwu Hospital, Capital Medical University. The patients presented with acute embolic occlusion of the SMA on admission and were initially diagnosed by computed tomography angiography(CTA). The patients who underwent endovascular treatment with a guiding catheter had no obvious evidence of bowel infarct. No intestinal necrosis was identified by gastrointestinal surgeons through peritoneal puncture or CTA. The complications, feasibility, effectiveness, safety, and mortality were assessed.RESULTS Six(75%) patients were male, and the mean patient age was 70.00 ± 8.43 years(range, 60-84 years). The acute embolic occlusion of the SMA was initially diagnosed by CTA. All patients had undertaken anticoagulation primarily, and percutaneous aspiration using a guiding catheter was then undertaken because the emboli had large amounts of thrombus residue. No death occurred among the patients. Complete patency of the suffering artery trunk was achieved in six patients, and defect filling was accomplished in two patients. The in-hospital
