In recent years,the topic sentiment model as an important research in the field of unsupervised learning,has been used in text topic mining and sentiment analysis.However,Weibo has brought some challenges to the topic sentiment model because of its short text and in complete structure.Therefore,the related research and improvement work of this paper will be carried out around the topic sentiment model of Weibo.We introduce the word vector technology to the popular model-TSMMF(topic sentiment model based on multi-feature fusion),use multivariate Gaussian distribution to sample neighboring words fast from the word embedding space,and replace the words generated by the Dirichlet multinomial distribution.Thus,the words with lowcooccurrence frequency and less information will be transformed into words with prominent topic and clear information.At the same time,the nearest neighbor search algorithm is used to further improve the running speed of the model when processing large-scale Weibo corpus,and then the GWE-TSMMF model is proposed.The experimental results show that the average F1 value of GWE-TSMMF model is about 0.718.The sentiment polarity analysis is better than the original model and the existing mainstream word embedding topic sentiment models (WS-TSWE and HST-SCW).

Objective: To investigate the genetic polymorphisms of 15 STRs loci in Chinese E Wen-ke population., Methods: DNA samples from 99 unrelated individuals in Chinese E Wen-ke population were screened by Power Plex 16 System and ABI3100 Genetic Analyzer., Results: The genotype frequencies of these 15 STR loci meet the Hardy-Weinberg expectation. The Matching probability of 15 STRs loci were between 0.0205-0.1733, discriminating power (DP) at 0.8267-0.9795, heterozygosity (Ho) at 0.6061-0.9091, power of exclusion (PE) at 0.4038-0.7690, polymorphism information content (PIC) at 0.5985-0.8734. The total DP of 15 STRs loci is 0.9999999999998., Conclusion: Our results showed that the 15 STRs loci of Power Plex 16 System are valuable STR loci genetic marker system having high DP and are useful in forensic case work in Chinese E Wen-ke population.

Objective: To investigate the genetic polymorphisms of 15 STRs loci in Chinese East Mongolian population., Methods: DNA samples from 105 unrelated individuals in Chinese East Mongolian population were screened by Power Plex 16 System and ABI3100 Genetic Analyzer., Results: The genotype frequencies of these 15 STR loci meet the Hardy-Weinberg expectation. The Matching probability of 15 STRs loci were between 0.0084-0.2169, discriminating power (DP) at 0.7831-0.9916, heterozygosity (H) at 0.5619-0.9231, power of exclusion (PE) at 0.4490-0.8444, polymorphism information content (PIC) at 0.5438-0.9178. The total DP of 15 STRs loci is 0.9999999999998., Conclusion: Our results showed that the 15 STRs loci of Power Plex 16 System are valuable STR loci genetic marker system having high DP and are useful in forensic case work in Chinese East Mongolian population.

The absorption spectra of photoinitiator cyclopentadiene-Fe-naphthalene tetrafluoroborate salt ([Cp-Fe-Naph]BF4) and ferocinium tetrafluoroborate salt([Cp-Fe-Cp]BF4), in two solvents have been studied. The influence of irradiation on the solution of photoinitiator has been observed. The kinetics of photolysis has been determined by real-time UV absorption spectrum. The results show that the photolysis reactions of two initiators are the first order reaction, the rate constant of photolysis reaction are 0.72 and 0.65 min-1, respectively. The photoinitiated mechanism of [Cp-Fe-Cp]BF4 was obtained.
