As pesticide residues in bayberry has raised serious concern from the public in China, a monitoring survey was carried out during 2013–2014 and 157 samples were analyzed in total. Twenty-three pesticides were detected among the 44 pesticides analyzed and at least one pesticide was detected in 63% of 99 samples. Whereas 45.6% of samples were found with two or more pesticide residues, and 23.6% of samples with four or more pesticide residues. Probabilistic risk assessments indicated that estimated daily intake（EDI） of cyhalothrin at the P97.5th percentile level is 1.11 times larger than the acceptable daily intake（ADI） for children, the estimated short-term intake（ESTI） at the P97.5th percentile level is 1.9 and 1.78 times larger than the acute reference dose（ARf D） for adult and children, respectively, indicating the potential risk concern from pyrethroids. EDI of the pesticides with anti-androgenic effects ranged from 0.15–2.46 of ADI, the probability of exposure exceeding the ADI was 7.1 and 31.1% for adults and children, respectively, the probability of exposure of pyrethroids exceeding the ADI was 3.8% for children. Exposures for other pesticides and groups were below 1.0. Because the co-occurrence of frequency of cyhalothrin and cypermethrin was 9.55%, the combinations of pesticides detected with anti-androgenic effects has not been found in the present monitoring, the results indicate that the pesticide residues in bayberry will not constitute serious public health risk, however, they are significant for the management of pesticide use on bayberry and dietary health risk in China.

This work reveals the significant effects of cobalt(Co)on the microstructure and impact toughness of as-quenched highstrength steels by experimental characterizations and thermo-kinetic *** results show that the Co-bearing steel exhibits finer blocks and a lower ductile-brittle transition temperature than the steel without ***,the Co-bearing steel reveals higher transformation rates at the intermediate stage with bainite volume fraction ranging from around 0.1 to *** improved impact toughness of the Co-bearing steel results from the higher dense block boundaries dominated by the V1/V2 variant ***,the addition of Co induces a larger transformation driving force and a lower bainite start temperature(BS),thereby contributing to the refinement of blocks and the increase of the V1/V2 variant *** findings would be instructive for the composition,microstructure design,and property optimization of high-strength steels.

Monoclonal antibodies(mAbs) are widely used in virus research and disease diagnosis. The nucleoprotein(NP) of influenza A virus(IAV) plays important roles in multiple stages of the virus life cycle. Therefore, generating conserved mAbs against NP and characterizing their properties will provide useful tools for IAV research. In this study, two mAbs against the NP protein, 10 E9 and 3 F3, were generated with recombinant truncated NP proteins(NP-1 and NP-2) as immunogens. The heavy-chain subclass of both 10 E9 and 3 F3 was determined to be IgG2α, and the light-chain type was κ. Truncation and site-specific mutation analyses showed that the epitopes of mAbs 10 E9 and 3 F3 were located in the N terminal 84–89 amino acids and the C terminal 320–324 amino acids of the NP protein, respectively. We found that mAbs 10 E9 and 3 F3 reacted well with the NP protein of H1–H15 subtypes of IAV. Both 10 E9 and 3 F3 can be used in immunoprecipitation assay, and 10 E9 was also successfully applied in confocal microscopy. Furthermore, we found that the 10 E9-recognized _(84) SAGKDP_(89) epitope and 3 F3-recognized 320 ENPAH324 epitope were highly conserved in NP among all avian and human IAVs. Thus, the two mAbs we developed could be used as powerful tools in the development of diagnostic methods of IAV, and also surely promote the basic research in understanding the replication mechanisms of IAV.

A scientific and rational evaluation on road-region ecosystem stability is the premise to properly deal with the relationship between highway constructing and ecological environment protecting to a sustainable development. Based on the connotative meaning and the procedure of evaluation on road-region ecosystem stability, this paper studied the principles and the method on determining the evaluation index system on road-region ecosystem stability. It put forward an index system for assessing road-region ecosystem stability as a reference. On the basis of detailed analyze of the multidimensional space of road-region ecosystem, a new multi-objective comprehensive evaluation method for road-region ecosystem stability is presented and a calculation tormula for multi-objective comprehensive level of road-region ecosystem stability. This method was used to evaluate road-region ecosystem stability of Lin-Chang highway. This method possessed definite theoretical value and reliability in practice.

凭借高效、无损和环保的优点,近红外光谱在多个领域广泛用作物质快速分析方法的同时,仍面临着光谱标定模型生命周期短,构建仪器标定迁移方法的标准样品难以获得和保存等问题。在化学计量学文献中,迁移方法通常能够矫正主从仪器之间的光谱差异,但绝大多数方法都需要在两台仪器相同条件下测量一组迁移标准样品。虽然样品数目不必过多,但总体上表明,必须对其进行很好的选择才能保证成功迁移。对于在主从仪器中选择代表性的样本子集,现有Kennard-Stone算法作为样本选择的主要算法。在标准样本的确定问题中,假设主仪器已找到标准样本,选择的样本集需要在从仪器中进行测量,仅当迁移样本足够稳定时才有可能,但现有近红外光谱技术无法保证这一点。如果假设使用从仪器的样本作为标准样本,考虑到新工业应用中光谱光源的变更,主仪器被从仪器代替,因此不再可用。基于目前存在的这些问题,提出了一种平均分布差异最小化的NIR标定迁移方法(MCT),此方法可以在不考虑从仪器标准样本(即标准样本自由)的情况下,针对近红外光谱数据的多重共线性,首先假设存在一个主从仪器光谱的共同偏最小二乘子空间,并将主从仪器光谱数据分别投影到该公共子空间;然后,引入平均分布差异最小化算法,即分别给出主从光谱数据在子空间的平均分布中心表示函数,在最小化两个光谱平均分布(中心点)的差异的同时,最大化投影后主仪器光谱的协方差,推导求解出最佳子空间;最后,将主光谱样本和从光谱预测样本分别投影到该偏最小二乘子空间中,利用主光谱数据得到回归模型,该模型可用于预测从光谱浓度。通过对玉米数据集和小麦数据集的测试研究,证明的预测效果与SBC,PDS,CCACT,TCR和MSC相比有所改善,该方法可以实现更低的预测误差。
