略论吸收新党员的主要标准——学习江泽民同志“七一”重要讲话体会

现代政党理论指出 :判断一个政党的性质不是根据党员的成份 ,而是根据党纲和指导思想。中国共产党历史上曾吸收农民和剥削阶级出身的知识分子入党。由于坚持思想上入党 ,保证了党的无产阶级性质。在新的历史时期 ,对民营科技企业的创业人员等七种人也可发展入党 ,其原因在于“能否自觉地为实现党的路线纲领而奋斗 ,是否符合党员条件 ,是吸收新党员的主要标准”。

基于类重叠度区分的大规模云平台任务终止状态预测

大规模云平台任务终止状态的预测是云资源调度策略优化的关键步骤。本文以Google云平台的计算调度系统Borg为对象进行研究,针对任务的各种终止状态极度不均衡和类重叠的问题,提出了一种类重叠度区分的自定义步长‐梯度提升决策树(SP‐GBDT)任务终止状态预测方法,对任务终止状态进行细粒度的多分类预测,提高少数类任务状态的预测准确率。首先将终止状态的多个类别拆分成若干个二类组合,通过支持向量数据描述模型(SVDD)筛选出类重叠度较低的最优二类组合。然后,分别对最优的二类组合进行扩展采样比例的自定义步长欠采样。最后构建梯度提升决策树模型,将欠采样之后的数据进行多分类。在Google云平台的运行监控日志数据集上进行验证,通过对比预测结果和预测过程的可解释性分析,SP‐GBDT模型能够很好地降低数据集的不均衡比例以及类重叠的程度。与决策树和随机森林等常用多分类预测方法相比,所提算法的F1‐score分别提高了30.39%和18.26%。

“Six-and-twelve” score for outcome prediction of hepatocellular carcinoma following transarterial chemoembolization. In-depth analysis from a multicenter French cohort

The“six-and-twelve”(6&12)score is a new hepatocellular carcinoma(HCC)prognostic index designed for recommended transarterial chemoembolization(TACE)candidates.Quick and easy to use by the sum of tumor size(cm)and number,this model identifies three groups with different survival time(the sum is≤6;or>6 but≤12;or>12);a survival benefit with TACE can be expected for HCC patients with a score not exceeding twelve.Recently,Wang ZW et al showed that the“6&12”model was the best system correlated with radiological response after the first TACE.Thus,we wanted to assess its survival prediction ability as well as its prognostic value and compared it to other systems(Barcelona Clinic Liver Cancer,Hong Kong Liver Cancer(HKLC)staging,Albumin-Bilirubin grade,tumor nodularity,infiltrative nature of the tumor,alpha-fetoprotein,Child-Pugh class,and Performance Status score,Cancer of the Liver Italian Program,Model to Estimate Survival for HCC scores,up-to-seven criteria)different from Wang ZW et al study in a multicenter French cohort of HCC including only recommended TACE candidates retrospectively enrolled.As previously demonstrated,we show that the"6&12”score can classify survival within this French cohort,with a prognostic value comparable to that of other systems,except HKLC staging.More importantly,the“6&12”score simplicity and ability in patients’stratification outperform other systems for a routine clinical practice.

Severity of dentofacial deformity, the motivations and the outcome of surgery in skeletal Class Ⅲ patients

Objective To study the relationship between severity of skeletal Class Ⅲ malocclusion and the patient's emotional status, as well as motivation for seeking surgical correction and satisfaction with the outcome of the surgery Methods One hundred and forty consecutive Chinese patients with skeletal Class Ⅲ malocclusion who had been treated with a combined orthodontic and surgical approach were studied Sixty seven percent (40 males and 54 females) responded to a questionnaire Fifty four percent had two jaw deformities, 32% mandibular hyperplasia and 14% maxillary hypoplasia Surgical procedures: 77% received two jaw surgeries, 15% maxillary advancement and 8% mandibular setback This was a retrospective study based on questionnaires with numerical scale ranked answers (0: not at all; 1: a little; 2: moderately; 3: quite a bit; and 4: extremely) Results ANB angle was significantly negatively correlated with feelings about the nickname related to their facial problems (embarrassment: r =-0 30, P <0 01; worn out r =-0 32, P <0 01; angry r = -0 24, P <0 05) ANB angle also had a significant negative correlation with the reasons for having the surgery (pressure from their friends: r =-0 21, P <0 05, and referred by physician: r =-0 24, P <0 05) Changes in life style as a result of surgery were significantly negatively correlated with the ANB angle before treatment, positive influence on relationships with the opposite sex ( r =-0 25, P <0 05), positive influence in social activiies ( r =-0 22, P <0 05) Conclusion The psychological status before surgery and the outcome following orthognathic surgery in patients with skeletal Class Ⅲ malocclusion were closely related to severity of the malocclusion
