Application of the Recognition Algorithm of News Sentiment Dissemination Tendency Based on Multi-Mode Information Fusion.

Since the popularity of the Internet, it is now customary for people to browse the news on the Internet. In the process of browsing news, there are often comments to express and spread personal emotions. This has become a very popular way of spreading news sentiment. This research is based on information fusion technology to realize the research on the identification algorithm of news sentiment communication tendency. Based on the research results of many scholars, this article first elaborates the definition, method, and framework of information fusion technology. In this paper, the corresponding technology is selected, and then in the research of the tendency recognition algorithm, an emotion tendency recognition algorithm based on the integrated probabilistic reasoning model is proposed. The algorithm proved its effectiveness and robustness through experiments. Finally, the experimental results show that in all the parameter combination conditions, the algorithm can not only reduce the feature dimension but also ensure the accuracy of recognition under the probability of 89%.

Change in the actin cytoskeleton during seismonastic movement of Mimosa pudica.

The seismonastic movement of Mimosa pudica is triggered by a sudden loss of turgor pressure. In the present study, we compared the cell cytoskeleton by immunofluorescence analysis before and after movement, and the effects of actin- and microtubule-targeted drugs were examined by injecting them into the cut pulvinus. We found that fragmentation of actin filaments and microtubules occurs during bending, although the actin cytoskeleton, but not the microtubules, was involved in regulation of the movement. Transmission electron microscopy revealed that actin cables became loose after the bending. We injected phosphatase inhibitors into the severed pulvinus to examine the effects of such inhibitors on the actin cytoskeleton. We found that changes in actin isoforms, fragmentation of actin filaments and the bending movement were all inhibited after injection of a tyrosine phosphatase inhibitor. We thus propose that the phosphorylation status of actin at tyrosine residues affects the dynamic reorganization of actin filaments and causes seismonastic movement.

Measles infection in pregnancy.

OBJECTIVES: Measles during pregnancy has deleterious effects on both the perinatal outcome and the mother. However, in-depth knowledge about gestational measles is lacking. The objectives of this study were to describe the clinical course of eight cases of gestational measles and to study the effect of measles and pregnancy on each other. METHODS: From late 2000 to early 2001, we experienced a measles outbreak with eight infected pregnant women. The clinical course of each case is described in detail. RESULT: Three of the four cases before 24 weeks of gestation ended in spontaneous abortion or stillbirth. The clinical course of the three abortions and stillbirth were singular because of the sudden onset of the abortion and the spontaneous pregnancy termination. In contrast, the four pregnancies after 25 weeks of gestation ended in live-term delivery and two out of the four neonates were diagnosed with congenital measles. There was no maternal death, instead two pneumonia cases and one hemorrhagic shock case. CONCLUSIONS: Gestational measles may potentially damage the fetus and is one of the serious complications that can occur during pregnancy.
