作者：郭焘伍叶锐国网江苏省电力有限公司信息通信分公司江苏电力信息技术有限公司

基于遗传算法的告警方法,因没有对网络节点与告警特征进行关联,导致告警信息传输中在信息匹配环节的对接不准确,产生错误的告警信息,致使告警正确率不足。因此,提出SDH传输网络节点非法入侵告警方法。对网络中入侵节点与已建立的入侵行... 详细信息

基于遗传算法的告警方法,因没有对网络节点与告警特征进行关联,导致告警信息传输中在信息匹配环节的对接不准确,产生错误的告警信息,致使告警正确率不足。因此,提出SDH传输网络节点非法入侵告警方法。对网络中入侵节点与已建立的入侵行为特征数据进行对比完成信息识别,然后由模糊层次分析法获得入侵节点处理后的综合评价,并输送至推理队列,将推理队列中的节点信息与历史数据中的告警数据相关联,计算两者的整体相似度以生成告警,对告警信息进行过滤提高准确性,完成SDH传输网络的入侵告警。试验中,试验组在模拟环境中对电网的告警正确率是98.79%,而对照组的告警正确率是92.66%,可以证明所设计告警方法的告警正确率相对来说较高。

This study aimed to develop original laboratory culture and sediment toxicity testing protocols for the freshwater gastropod Bellamya aeruginosa （Reeve）, a new potential species for sediment toxicity testing. B. aeruginosa was successfully cultured with an effective culture system under proposed laboratory conditions. Optimal ad libitum feeding levels for larvae, juveniles, and adults were 2.0, 6.0, and 16.0 mg fish food/（***）, respectively. Mean survival rates of juveniles were higher than 90%, The snails could be sexed at 9 weeks of age, and their generation time is approximately 4 months. Reproduction continued all year around; the mean fecundity was 0.55 newborn/（***）. The utility of this species for bioassays was evaluated in both 10-day and 28-day case studies with artificial sediments. The 10-day LC50 of Cu for larvae was 480 μg/g dry weight （dw）, and the lowest observed effects concentration of Cu for survival and growth of larvae was 195 μg/g dw. Survival and growth are reliable indicators of acute toxicity. Larvae accumulated more Cu than adults. B. aeruginosa exhibited a higher sensitivity to Cu exposure than standard test species （Hyalella azteca and Chironomus tentans）. The 28-day test of sediment toxicity with adults showed that fecundity was a robust endpoint indicator of reproductive toxicity, and the biochemical endpoints of superoxide dismutase, catalase, and glutathione could be used as sensitive biomarkers for Cu-induced oxidative damage. B. aeruginosa can be therefore recommended as a candidate for the standardization of the freshwater sediment toxicity test protocol.

The paper specifically introduces the composition, principle and realization ofa distributed mutlimedia intelligent meta-synthesis system oriented to remote diagnoses and education--Lower Mandibular Third Molar Intelligent Meta-synthesis System. With the OOL--Delphi3.0/4.0, the expert intelligent subsystem implements the function of resistance analysis and the computer aided decision-making to the disign of drawing teeth of lower mandibular third molar. For the sake of remote diagnoses, the system adopts FrontPage98 to design home pages which can be interfaced in IE and NETSCAPE easily.

AIM: To investigate the therapeutic effects of emodin in combination with baicalein on severe acute pancreatitis (SAP) rats and to explore the mechanism of SAP. METHODS: A total of 112 SAP rats induced by retrograde injection of 5% sodium taurocholate into the biliarypancreatic duct, randomly assigned to a untreated group and three treated groups emodin group, combined emodin and baicalein group, and sandostatin group. Meanwhile, another 28 other rats were selected as sham operation (SO) group. There were 28 rats in each group, 8 rats were in 3 and 6 h groups respectively, and 12 rats in 12 h group. At each time-points, survival rates, ascites volumes, pathological lesion scores of pancreas tissues, serum amylase, tumor necrosis factor-α and IL-6 levels were determined as the indexes of therapeutic effects. RESULTS: The survival rate at 12 h was significantly higher in three treated groups than in untreated group. The ascites volume at 12 h was remarkably less in combined and sandostatin groups than in emodin group, but there was no difference between combined group and sandostatin group (P＞0.05). Serum amylase levels at all time-points were significantly lower in three treated groups than in untreated group. However, they had no difference among treated groups (P＞0.05). Serum TNF-α were lower in three treated groups than in untreated group at all time points. Among the three treated groups, at 6 h, the TNF-α levels of combination and sandostatin groups were lower than those of emodin group. These was no difference between combined and sandostantin. Serum IL-6 concentration at 3 h were lower in combined and sandostatin groups than in untreated group, but at 6 and 12 h they were lower in all treated groups than in untreated group and the combined and sandostatin groups and in emodin group, no difference was found between combined and sandostatin groups at all time-points (P＞0.05). The pathological scores of pancreas at all time points were significantly lower in thre

劳动收入份额是影响区域收入差距和经济可持续发展的重要因素,对实现发展成果共享意义重大,缩小地区间劳动收入份额差异将有助于区域协调发展。本文根据266个地级市制造业微观企业数据,运用系统GMM方法,实证分析资源错配程度对地区间劳动收入份额差异的影响。结果表明:资源错配对地区劳动收入份额有显著负向影响,使用不同的资源错配测算方法、剔除直辖市及分区域讨论也均支持这一结论。因此,通过深入推进供给侧改革,进一步减少非市场因素对资源配置的影响,既是新形势下经济高质量发展的动力,也是新时代缩小地区劳动收入份额差异的重要方略。
