Dempster-Shafer Inconsistency Values

For several ontology constructing reasons of migration, extending or merging, the size of ontolo- gies grows and applications become more complex, it is inevitable for us to receive an inconsistent ontology. Mea- suring ontology inconsistency is the basis inconsistency- dealing, which can help us decide how to act on an incon- sistency. Measuring ontology inconsistency with weighted formulae in numerous applications is a significant but diffi- cult task for most efforts which only deal with the fiat on- tology. This paper improves inconsistency measure based on evidence theory and proposes a novel Dempster-Shafer ontology inconsistency measure method. The logical prop- erties of these measures are studied. The properties show how to look inside the formulae and how to indicate the contribution of each formula to the overall inconsistency in the ontology set. This approach would provide us with a stronger base of inconsistency handling.

YAG激光对兔唇内侧粘膜急性损伤阈值的探讨

各种激光作用于皮肤的急性损伤阈值及组织学检查，国内外同行已多有研究。目前YAG激光广泛用于治疗口腔内各种病变，由于YAG激光穿透深度比其它激光要深，容易对正常组织产生急性损伤。本文采用国内研究人员普遍运用的研究手段，讨论了YAG激光照射兔唇内侧粘膜后产生的红斑反应，求出最小反应几率达50％的辐照量ED50，并与皮肤的急性损伤阈值比较，为YAG激光的口腔及粘膜等防护提供一理论上的参考数据。     

基于DCE-MRI影像的深度多任务学习联合预测乳腺癌病理信息研究

乳腺癌病理信息中的Ki-67表达水平、分子分型及组织学分级等信息可为患者提供预后信息,本文提出一种基于深度多任务学习对乳腺癌多种病理信息联合预测的方法.回顾性分析202例术前,化疗前的浸润性导管癌患者乳腺DCE-MRI影像,将数据集随机分为训练集122例,测试集80例.分割影像的含肿瘤的腺体区域,并获得6个减影序列,利用深度学习结合多任务学习方法对Ki-67表达、分子分型及组织学分级中任意显著相关的两个任务进行联合预测,并计算AUC评估模型的分类性能.多任务学习影像模型预测Ki-67表达、Luminal A和组织学分级的最佳AUC为0.804,0.757,0.724.实验结果表明,深度多任务学习可以很好的预测乳腺癌病理信息的性能,对乳腺癌的诊断和个性化治疗方案的选择具有重要意义.     

Microstructure of AISI 304 stainless steel strips produced by a twin-roll caster

By optical inspection of macro-etched metallography and electron back-scattered diffraction (EBSD) mapping,this paper analyzed the microstructure of anstenitic stainless steel strips produced with an equal-diameter twin-roll strip caster.The results indicate that the microstructure of the strips includes two columnar zones with highly compact dendrites and one equiaxed zone.The characteristics,such as grain size and growing direction of columnar grains and equiaxed grains,were investigated.An additional transitional area with many freer grains between the columnar zone and the equiaxed zone was found.As shown in EBSD analysis,small angle boundaries exist both in the columnar zone and the equiaxed zone,although they are especially more in the transitional area.Additionally,some <111> twin boundaries were found in the mierostructure of the strips.

仿刺参体壁的组织学和组织化学

用组织学和组织化学方法对仿刺参Apostichopus japonicus体壁的结构和成分进行了研究。组织学研究结果表明:仿刺参体壁自外向内由上皮层、结缔组织层、肌肉层和体腔上皮层组成。上皮层主要包括一层薄的角质层和2³层上皮细胞,结缔组织层内含丰富的胶原纤维,肌肉层主要是平滑肌,体腔上皮层由单层扁平上皮组成。组织化学研究结果表明:仿刺参体壁各层(除体腔上皮层外)均富含糖类和蛋白质,不含脂类;碱性磷酸酶和酸性磷酸酶在体壁中存在酶活性的部位相同,主要在结缔组织层的空洞状结构处以及结缔组织层与肌肉层交联处。
