利用柔性多层带材,提出了一种Electromagnetic Interference(EMI)滤波器的集成结构。该结构单独设计了差模绕组,并将滤波器中所有无源元件都集成在同一磁心中。文章通过建立集成滤波器的分布模型,从差、共模电流分布和磁路的角度,分别阐述了差、共模电感的集成原理,并给出了计算公式和集成结构的设计要点。实验部分比较了在不同差模电感下,差模插入损耗特性和EMI测试结果。实验表明,集成滤波器比分立滤波器体积更小,高频特性改善显著。

Blockade of immune checkpoints has recently emerged as a novel therapeutic strategy in various tumors. In particular,monoclonal antibodies targeting programmed cell death 1(PD-1) or its ligand(PD-L1) have been most studied in lung cancer,and PD-1 inhibitors are now established agents in the management of non-small cell lung cancer(NSCLC). The reports on highprofile clinical trials have shown the association of PD-L1 expression by immunohistochemistry(IHC) with higher overall response rates to the PD-1/PD-L1 axis blockade suggesting that PD-L1 expression may serve as a predictive marker. Unfortunately,however, each PD-1 or PD-L1 inhibitor is coupled with a specific PD-L1 antibody, IHC protocol and scoring system for the biomarker assessment, making the head-to-head comparison of the studies difficult. Similarly, multiple clinical series that correlated PD-L1 expression with clinicopathologic and/or molecular variables and/or survival have reported conflicting *** discrepancy could be explained by the differences in ethnicity and/or histologic types included in the studies, but it appears to be attributed in part to the differences in PD-L1 IHC methods. Thus, orchestrated efforts to standardize the PD-L1 IHC are warranted to establish the IHC as a predictive and/or prognostic biomarker in NSCLC.

Two full-scale systems operated in parallel, a conventional A2/O system consisting of anaerobic, anoxic and oxic compartments in succession and an inverted system consisting of anoxic, anaerobic and oxic compartments without internal recycle, were compared in terms of their phosphorus removal performance, with an emphasis on phosphate （P） release behaviors, using both operational data and simulation results. The inverted system exhibited better long-term phosphorus removal performance （0.2 ± 0.3 vs. 0.7 ±0.7 mg/L）, which should be attributed to the higher P release rate （0.79 vs. 0.60 kg P/（kg ***）） in the non-aerated compartments. The P release occurred in both the anoxic and anaerobic compartments of the inverted system, resulting in more efficient P release. Although the abundances of the ＇Candidatus Accumulibacter phosphatis＇ population in the two systems were quite similar （（19.1 ＋ 3.27）% and （18.4 ＋ 4.15）% of the total microbe （DAPI stained particles） population in the inverted and conventional systems, respectively, by fluorescence in situ hybridization （FISH））, the high-concentration DAPI staining results show that the abundances of the whole polyphosphate accumulating organisms （PAOs） in the aerobic ends were quite different （the average ratios of the poly-P granules to total microbes （DAPI stained particles） were （45 ±4.18）% and （35 ± 5.39）%, respectively）. Both the operational data and simulation results showed that the inverted system retained more abundant PAO populations due to its special configuration, which permitted efficient P release in the non-aerated compartment and better P removal,

In this study, the performance of nitrogen and phosphorus removal in a full-scale closed-loop bioreactor （oxidation ditch） system was simulated using the ASM2d model. Routine data describing the process for two years were compiled for calibration and validation. To overcome the identifiability problem, the classic Bayesian inference approach was utilized for parameter estimation. The calibrated model could describe the long-term trend of nutrient removal and short-term variations of the process performance, showing that the Bayesian method was a reliable and useful tool for the parameter estimation of the activated sludge models. The anoxic phosphate uptake by polyphosphate accumulating organisms （PAO） contributed 71.2% of the total Poly-P storage, which reveals the dominance of denitrifying phosphorus removal process under the oxygen limiting conditions. It was found that 58.7% of the anoxic Poly-P storage and denitrification by PAO in the reactor was achieved in the aerated compartment, implying that the PAO＇s anoxic activity was significantly stimulated by the low dissolved oxygen （DO） level in this compartment due to the oxygen gradient caused by brush aerator.

对目标微生物的准确定量是研究微生物群落的组成与功能的重要前提。荧光定量PCR技术作为目前流行的核酸定量分析技术,具有操作时间短,敏感性高,特异性强等特点,但也存在由客观因素导致实验结果出现显著误差的缺点。针对目前环境微生物定量方法中容易忽略的污泥样品DNA保存步骤与上机时间等环节,详细探讨了保存条件、上机批次对聚磷菌(PAOs)荧光定量PCR结果的影响。结果显示保存温度、保存时间均对标准质粒和污泥DNA样品中PAOs定量结果产生影响:模板DNA的浓度及保存时间会影响标准曲线Ct值的重复性;同一样品在相同保存温度(4℃)、不同保存时间、不同批次条件下的定量结果存在显著性差异(P0.05)。因此,在对活性污泥样品进行定量分析时,DNA样品应平行保存于-20℃条件,尽量避免反复冻融,并确保对比的生物样品保存及上机条件完全一致,从而减少定量结果误差。

Bituminous sub-ballast is an alternative solution to the unbound granular sub-ballast used in the railway track due to several benefits that it can provide. Indeed, it contributes to maintain the moisture content in the subgrade unchanged during all year. This decreases the subgrade deterioration process. Moreover, the presence of bituminous sub-ballast can also reduce vertical stiffness variations on the track; it can have a positive effect in the maintenance needs at transition sections （bridge-embankment） and in the attenuation of the vibrations induced by the rail traffic. Despite the importance of the presence of the bituminous sub-ballast to conceive the construction and/or rehabilitation of sustainable infrastructure, in literature, there are only fragmentary information regarding the definition of benchmark criteria for their mix design. The superpave mix design approach used in road domain is applied systematically in the railway domain, without being adjusted for different load configuration of the rail track system. This research work aims at defining the benchmark criteria for the bituminous sub-ballast mix design to reduce the approximations involved in the recipe optimization due to the limitation of applying the superpave system in the railway domain. The methodology proposed aims at selecting the RESAL （rail equivalent single axle load） and therefore, transforming the entire traffic spectrum on the track lines in number of ESALs. Afterwards, the Ndesign has been calculated as function of the rail traffic level. Finally, a case study of bituminous sub-ballast mix design has been investigated for a first verification of the methodology proposed.
