泗河水体氮磷空间分布及富营养化评价

分析了泗河水体中TN和TP的空间变化规律,利用对数型幂函数普适指数公式对其水体营养状态进行了评价.结果表明,泗河水体中TN的平均质量浓度为6.22mg·L-1(NO-3-N占34.20%),TP为0.33mg·L-1.泗河水体中氮、磷空间分布特征明显,TN和NO-3-N的空间分布比较一致,均由上游开始先升高后降低的趋势,而NH+4-N稍有不同,无明显的变化趋势;TP和SRP含量由上游开始先降低后升高,分别至泗河大桥断面(1-8#)和金口坝断面(1-9#)达到最高值,然后又逐渐降低.总体来看,泗河处于"富"营养状态(EI=48.757).其中,3个断面(15.80%)处于"中"营养状态,13个断面(68.42%)处于"富"营养状态,3个断面(15.80%)处于"重富"营养状态.综合分析表明,工业废水和生活污水的点源污染是泗河污染的主要来源,畜禽养殖和农业面源污染应引起高度重视.     

High-precision orbit prediction and error control techniques for COMPASS navigation satellite

A new satellite orbit prediction method based on artificial neural network （ANN） model is proposed to improve the precision of orbit prediction. In order to avoid the difficulty of amending the dynamical model, it is attempted to use ANN model to learn the variation of orbit prediction error, and then the prediction result of ANN model is used to compensate the predicted orbit based on dynamic model to form a final predicted orbit. The experiment results showed that the orbit prediction error based on ANN model was less than that based on dynamical model, and the ent satellites and different improvement effects for differtime were different. The maximum rates of improvement of predicting 8, 15, 30 d were respectively 80 %, 77.77 %, 85 %. The orbit prediction error control technique based on the method of back overlap arc compare was brought forward to avoid the risk that the precision of predicted orbit is even worse after it is compensated by ANN model. The phenomena of failure were basically eliminated based on this technique, and the rate of failure was reduced from 30 % to 5 %. This technique could ensure that the engineering application of ANN model could come true.     

Single-trial decoding of imagined grip force parameters involving the right or left hand based on movement-related cortical potentials

Time–domain feature representation for imagined grip force movement-related cortical potentials(MRCP)of the right or left hand and the decoding of imagined grip force parameters based on electroencephalogram(EEG)activity recorded during a single trial were here investigated.EEG signals were acquired from eleven healthy subjects during four different imagined tasks performed with the right or left hand.Subjects were instructed to execute imagined grip movement at two different levels of force.Each task was executed 60 times in random order.The imagined grip force MRCP of the right or left hand was analyzed by superposition and averaging technology,a single-trial extraction method,analysis of variance(ANOVA),and multiple comparisons.Significantly different features were observed among different imagined grip force tasks.These differences were used to decode imagined grip force parameters using Fisher linear discrimination analysis based on kernel function(k-FLDA)and support vector machine(SVM).Under the proposed experimental paradigm,the study showed that MRCP may characterize the dynamic processing that takes place in the brain during the planning,execution,and precision of a given imagined grip force task.This means that features related to MRCP can be used to decode imagined grip force parameters based on EEG.ANOVA and multiple comparisons of time–domain features for MRCP showed that movement-monitoring potentials(MMP)and specific interval(0–150 ms)average potentials to be significantly different among 4 different imagined grip force tasks.The minimum peak negativity differed significantly between high and low amplitude grip force.Identification of the 4different imagined grip force tasks based on MMP was performed using k-FLDA and SVM,and the average misclassification rates of 27%±5%and 24%±4%across 11 subjects were achieved respectively.The minimum misclassification rate was 15%,and the average minimum misclassification rate across 11 subjects was24%±4.5%.This investigation indicates that imagined grip force MRCP may encode imagined grip force parameters.Single-trial decoding of imagined grip force parameters based on MRCP may be feasible.The study may provide some additional and fine control instructions for brain–computer interfaces.     

Biological correlates of psychological states among young children: a cross-sectional examination of roles of aspartate transaminase/alanine aminotransferase,insulin, and cytokines

Compared to data on adolescents and adults, limited research has been conducted on biological corre- lates among young children with possible psychological difficulties, especially in Asian countries. By focusing on various peripheral biochemical indicators, we investigated potential biological correlates of psychological states in a community sample of Taiwanese school children aged 6-10 years. In total, 307 students （159 obese children and 148 normal-weight children） were selected from first- and fourth-grade school children in eight elementary schools in the Taipei metropolitan area in 2009. These children underwent a comprehensive health examination, including a physical examination, blood sample analysis, and questionnaire administration in a hospital. Differences in anthropometric and serum biochemical readings were compared between children with average and worse levels on each of the five psychological domains. We found that interleukin （IL）-1β [β = 1.29, 95 % confidence interval （CI） 0.50-2.09], IL-10 （β = 1.61, 95 % CI 〈0.01-3.24）, fasting blood glucose （β = 0.08, 95 % CI 0.01-0.15）, homocysteine （β = 0.63, 95 % CI 0.09-1.18）, and aspar- tate transaminase （AST） （β = 0.15, 95 % CI 〈0.01-0.31） were significantly positively associated with anxiety. In addition, IL-113, insulin, AST, and alanine aminotransam- inase （ALT） were significantly positively associated with depression. Anger and disruptive behaviors were also related to specific biological correlates. Specific biological correlates, including AST/ALT, cardiovascular disease- related variables, and specific cytokines, were linked to particular psychological states among young children in this Asian population. These might provide a route for better understanding the biological aspects of children＇s mental health and might contribute to research on diag- nostic or predictive biomarkers for psychiatric diseases in young children.

Cellular prion protein imaging analysis with aptamer-labeled Ru（bpy）32＋-doped silica nanoparticles

A new type of highly selective aptamer-labeled fluorescent silica nanoparticles [Apt-tris（2,2＇-bipyri- dyl）ruthenium（II）@SiO2 NPs] were prepared through the reverse microemulsion method by using prolonged fluorescence lifetime ruthenium complexes of tris（2,2＇-bipyri- dyl）ruthenium（II） （Ru（bpy）2＋） as the source of the fluorescence for cellular prion protein imaging. Investigations showed that the newly prepared Ru（bpy）32＋@Si02 NPs possessed superior advantages of strong fluorescence, low toxicity, and easy surface modification for bioconjugation. Cell imaging experiments indicated that Apt- Ru（bpy）32＋@SiO2 NPs had great tendency to human bone marrow neuroblastoma cells （SK-N-SH cells）, since they can express large amount of prion protein on the surface of the cell, while in HeLa cells this phenomenon disappeared for the reason that HeLa cells cannot express prion proteins.
