提出了一种多标签符号型属性值划分的聚类方法(clustering method for multi-label symbolic value partition, CMSVP)。首先,利用标签排序和K-means算法,对原始标签信息进行聚类。然后,为每一个属性构建一个无向加权图。图中的每一个节点代表一个属性值,边的权重则表示节点之间的相似度。最后,对所有的无向加权图进行随机游走,得到属性值的聚类方案。实验在6个多标签数据集上进行。结果表明,CMSVP算法在对数据有效地进行压缩的同时,也能在一定程度上提高数据的分类性能。

Background The effects of anxiety and depression on the recurrence of persistent atrial fibrillation （AF） after circumferential pulmonary vein ablation （CPVA） are not clear. Whether CPVA can alleviate the anxiety and depression symptoms of persistent AF patients is unknown. Methods One hundred and sixty-four patients with persistent AF, of which 43 treated with CPVA （CPVA group） and 103 treated with anti-arrhythmics drugs （medicine group）, were enrolled. The Zung Self-Rating Anxiety Scale （SAS）, and Zung Self-Rating Depression Scale （SDS） were assessed before and 12 months after treatment in all patients. Results The scores of SAS （40.33±7.90 vs. 49.76±9.52, P 〈0.01） and SDS （42.33±8.73 vs. 48.17±8.77, P 〈0.01） decreased 12 months after CPVA. Over 12 months follow-up, AF relapsed in 17 patients in CPVA group. Compared with the data in the recurrent group （17 patients）, the scores of SAS and SDS were significantly lower in the non-recurrent group （26 patients） at baseline. The results of multivariate Logistic regression analysis showed normal scores of SAS and SDS were the independent risk factors of AF recurrence after CPVA. Conclusions Anxiety and depression increase the recurrence risk of persistent AF after CPVA. CPVA can ameliorate the anxiety and depression symptoms in patients with persistent AF.

Functional magnetic resonance imaging(MRI) provided critical functional information in addition to the anatomicprofiles offered by conventional MRI, and has been enormously used in the initial diagnosis and followed evaluation of various diseases. Diffusion tensor imaging(DTI) is a newly developed and advanced technique that measures the diffusion properties including both diffusion motion and its direction in situ, and has been extensively applied in central nerve system with acknowledged success. Technical advances have enabled DTI in abdominal and pelvic organs. Its application is increasing, yet remains less understood. A systematic overview of clinical application of DTI in abdominal and pelvic organs such as liver, pancreas, kidneys, prostate, uterus, etc., is therefore presented. Exploration of techniques with less artifacts and more normative postprocessing enabled generally satisfactory image quality and repeatability of measurement. DTI appears to be more valuable in the evaluation of diffused diseases of organs with highly directionally arranged structures, such as the assessment of function impairment of native and transplanted kidneys. However, the utility of DTI to diagnose focal lesions, such as liver mass, pancreatic and prostate tumor, remains limited. Besides, diffusion of different layers of the uterus and the fiber structure disruption can be depicted by DTI. Finally, a discussion of future directions of research is given. The underlying heterogeneous pathologic conditions of certain diseases need to be further differentiated, and it is suggested that DTI parameters might potentially depict certain pathologic characterization such as cell density. Nevertheless, DTI should be better integrated into the current multi-modality evaluation in clinical practice.

Laboratory-based pathogen isolation, identification, and toxicity determination were performed on samples from a suspected case of infant botulism. Mice injected with cultures generated from the enema sample and ingested Powered infant formula （PIF） presented typical signs of botulism. Antitoxins to polyvalent botulinum neurotoxins （BoNTs） and monovalent BoNT type B antitoxin had protective effects. Clostridium botulinum isolated from the enema and residual PIF samples were positive for type B toxin. Pulsed-field gel electrophoresis （PFGE） revealed that the two strains of C. botulinum isolated from the two samples produced indistinguishable pulsotypes. These findings confirmed this case of type B infant botulism associated with the ingestion of PIF contaminated bv type B C. botulinum spores.

燃料润滑性是用作压燃式发动机的燃料的重要特性之一。煤基燃料二甲醚、甲醇和F-T柴油都是压燃式发动机的良好清洁代用燃料,但是这些煤基代用燃料的物理化学特性与传统的柴油燃料不同,当前的燃料润滑性评定方法可能不是非常适用于这些煤基燃料,因此研究这些煤基燃料润滑性的评定方法是当务之急。分析了国际上通用的燃料润滑性评定方法HFRR、BOCLE和SLBOCLE方法的优缺点,并指出油泵试验法可能是一种较适合煤基车用替代燃料润滑性评定的方法。

为探讨样地扰动对生态学野外控制试验的影响,在介绍一个较大型森林降水格局野外控制试验的基础上,分析了试验平台建设的设施对土壤化学性质和净氮(N)转化速率所产生的影响。结果表明,整个约0.7 hm2样地在2012年5–9月间的土壤有机C(SOC)、全N(TN)、硝态N、铵态N、微生物生物量C(MBC)、净N矿化速率和硝化速率均表现出一定的时空变异,但设施对SOC、TN、硝态N、铵态N和净矿化速率的影响统计学检验不显著;而设施建设和样方周边挖隔离沟对净N硝化速率在刚完成平台建设时有显著影响(P<0.05),但恢复3个月后虽仍有差异,但统计学检验已不显著。这些提示了在分析和解释降水处理对净N硝化速率的影响效应时,应注意设施效应和坡位差异的潜在影响。

Feature models have been widely adopted to reuse the requirements of a set of similar products in a domain. In feature models＇ construction, one basic task is to ensure the consistency of feature models, which often involves detecting and fixing of inconsistencies in feature models. While many approaches have been proposed, most of them focus on detecting inconsistencies rather than fixing inconsistencies. In this paper, we propose a novel dynamic-priority based approach to interactively fixing inconsistencies in feature models, and report an implementation of a system that not only automatically recommends a solution to fixing inconsistencies but also supports domain analysts to gradually reach the desirable solution by dynamically adjusting priorities of constraints. The key technical contribution is, as far as we are aware, the first application of the constraint hierarchy theory to feature modeling, where the degree of domain analysts＇ confidence on constraints is expressed by using priority and inconsistencies are resolved by deleting one or more lower-priority constraints. Two case studies demonstrate the usability and scalability （efficiency） of our new approach.
