为了提升泛在物联网中电力能源工程数据的处理效率,文中对该场景下的数据采集和处理流程进行了研究。该研究基于矩阵的低秩理论,将缺失数据的补全抽象为矩阵秩最小化的目标函数问题,并对原有基于交替方向乘子法(ADMM)的迭代方法进行了改进,从而得到了IADMM方法。同时,通过引入支持向量机(SVM)来处理电力工程造价数据,并采用粒子群算法(PSO)对SVM的参数加以优化,从而提升了参数的收敛速度。基于某实际变电工程的采集数据对所提方法进行的仿真验证结果表明,当数据缺失率为50%时,IADMM算法的数据恢复误差为1.29%,收敛速度较ADMM算法提升了63.95%。且在电力工程造价预测时,PSO-SVM算法比BP网络、FCM-SVM算法的预测误差分别降低了3.24%和2.95%。

为改善以往生物浸铀效率不高的缺陷,通过添加外源Fe^(2+)及改变矿物粒径来提高生物对铀的浸出率。研究结果表明:外源Fe^(2+)浓度分别为0、0.5、1.0和2.0 g/L时,铀浸出率分别为87.34%、88.27%、91.23%、89.13%,当浸出体系中Fe^(2+)浓度为1.0 g/L时,铀矿石会产生部分溶解且表面粗糙孔隙明显,有利于铀的浸出,溶浸液中存在适量的Fe^(2+)对生物浸铀的能力具有提升效果。另外,外源Fe^(2+)对铀矿生物浸出符合固体产物层控制模型,浸出过程主要受扩散控制。当粒径<-2 mm和-5 mm时铀浸出率分别为91.23%和83.70%,矿物粒径适当减小可增大颗粒比表面积,同样利于铀的浸出。

目的探讨三伏灸治疗变应性鼻炎(AR)的效果及其对血清总IgE的影响,以期为此病的临床效果评价提供客观依据。方法选取50例AR患者作治疗组,行三伏灸治疗,观察6个月后的近期效果,于治疗前后检测血清总IgE水平;并选取25例健康体检者作对照组,检测血清总IgE水平。结果治疗组的总有效率为86.0%(43/50)。治疗前,治疗组患者血清总IgE阳性有39例(占78.0%),且血清总IgE水平明显高于对照组(P<0.01);经过三伏灸治疗后,治疗组血清总IgE水平明显降低,但仍明显高于对照组(P<0.01)。结论AR患者经三伏灸治疗后,血清总IgE水平明显降低,可为AR的疗效评价提供客观依据。三伏灸可通过降低IgE水平达到治疗AR的效果。

OBJECTIVE： To explore the nature of ＂Yin internal heat caused by Yin-deficiency＂ in terms of the theo- ry of Traditional Chinese Medicine, by studying en- ergy metabolism in rats with Yin-deficiency-heat syndrome and analyzing the gene expression pro- file of their livers. METHODS： A Yin-deficiency-heat syndrome model was induced in rats using three Chinese medicinal herbs. Glycogen and triglycerides in blood plasma, and the enzyme activity of ATP in livers were mea- sured colorimetrically. Triiodothyronine （T3）, thyrox- ine （T4）, and thyroid stimulating hormone levels in blood plasma were also measured with enzyme linked immunosorbent assay. The gene expression profile of livers was detected with gene chip analy- sis. Differentially expressed genes were screened out and classified according to Gene Ontology. The accuracy of results were examined with reversetranscription-polymerase chain reaction RESULTS： Compared with the control group, body weight （P〈0.05） and hepatic glycogen （P〈0.05） were significantly lower in the Yin-deficiency-heat syndrome group. Moreover, toe temperature （P〈 0.01） and triglyceride （P〈0.05）, Na ＋-K＋-ATPase （P〈 0.01）, Mg2＋-ATPase （P〈0.01）, T3 （P〈0.05）, and 1-4 （P〈 0.01） levels were significantly higher. There were 99 differentially expressed genes in livers from the Y/n-deficiency-heat syndrome group. Genes were mainly related to sterol synthesis （Pc=0.0392）, de- fense response （Pc=0.0448）, and sterol metabolism （Pc=0.0533）. CONCLUSION： Abnormal expression genes in rats with Yin-deficiency-heat syndrome prompted the synthesis and metabolism of cholesterol, increased energy consumption, and reduced defense re- sponse. This gene expression might be the molecu- lar mechanism underlying ＂internal heat caused by Yin-deficiency＂ in the rats with Yin-deficiency-heat syndrome.
