汽车背门一般通过铰链、锁销、缓冲块等约束系统安装和固定在车身上,其刚体模态振动与车内声腔声压耦合,是导致低频轰鸣声的主要原因.本文建立了背门振动-乘员舱声压的一维板-腔耦合声学解析模型,分析研究了边界约束刚度对板件振动速度响应及腔内耦合声压的影响规律,并进行了实车实验验证;通过调节锁销相对位移和缓冲块相对高度,解决了某车型低频敲鼓声问题.分析结果表明:在板件刚体模态振动下,腔内耦合声压幅值沿远离板件方向逐渐增大,且在声腔底部位置最大;板件振动速度相应及腔内耦合声压峰值幅值随边界约束系统刚度减小而降低;在低频轰鸣发生的20~30 Hz频率范围内,乘员舱前排位置声压峰值幅值比中排及后排位置大约8 dB(A),验证了理论分析结果的正确性;乘员舱内耦合声压峰值幅值随着锁销相对位置的增大和缓冲块相对高度的减小而降低,锁销相对车身向车尾方向增大2 mm或者缓冲块相对高度减小2 mm,可以使背门振动速度减小约0.002~0.003 m/s,前排声压峰值幅值降低3.5~14.8 dB(A).

具有非对称电磁响应特性的单向类电磁诱导透明效应(EIT-like)是超材料领域重要的研究课题之一,然而目前缺少可动态切换的单向EIT-like实现手段。基于此,提出一种利用二端口的微带谐振腔与两个开口谐振环之间的耦合作用构造单向EIT-like的方法,只有特定端口能够激发出EIT-like效应,其非对称反射系数对比度达到98.7%。在此基础上,结合可调的复合左右手传输线,对微带谐振腔与开口谐振环间的耦合情况进行动态调控,从而改变单向EIT-like的激发端口,实现了激发端口可电切换的单向EIT-like,推动EIT-like在光学存储、光调制、传感等方面的应用。

Exclusive responsiveness to ultraviolet light (~3.2 eV) and high photogenerated charge recombination rate are the two primary drawbacks of pure TiO_(2). We combined N-doped graphene quantum dots (N-GQDs), morphology regulation, and heterojunction construction strategies to synthesize N-GQD/N-doped TiO_(2)/P-doped porous hollow g-C_(3)N_(4) nanotube (PCN) composite photocatalysts (denoted as G-TPCN). The optimal sample (G-TPCN doped with 0.1wt% N-GQD, denoted as 0.1% G-TPCN) exhibits significantly enhanced photoabsorption, which is attributed to the change in bandgap caused by elemental doping (P and N), the improved light-harvesting resulting from the tube structure, and the upconversion effect of N-GQDs. In addition, the internal charge separation and transfer capability of0.1% G-TPCN are dramatically boosted, and its carrier concentration is 3.7, 2.3, and 1.9 times that of N-TiO_(2), PCN, and N-TiO_(2)/PCN(TPCN-1), respectively. This phenomenon is attributed to the formation of Z-scheme heterojunction between N-TiO_(2) and PCNs, the excellent electron conduction ability of N-GQDs, and the short transfer distance caused by the porous nanotube structure. Compared with those of N-TiO_(2), PCNs, and TPCN-1, the H2 production activity of 0.1%G-TPCN under visible light is enhanced by 12.4, 2.3, and 1.4times, respectively, and its ciprofloxacin (CIP) degradation rate is increased by 7.9, 5.7, and 2.9 times, respectively. The optimized performance benefits from excellent photoresponsiveness and improved carrier separation and migration efficiencies. Finally, the photocatalytic mechanism of 0.1% G-TPCN and five possible degradation pathways of CIP are proposed. This study clarifies the mechanism of multiple modification strategies to synergistically improve the photocatalytic performance of 0.1% G-TPCN and provides a potential strategy for rationally designing novel photocatalysts for environmental remediation and solar energy conversion.

Deep Guided Attention Network for Joint Denoising and Demosaicing in Real Image

4-hydroxynonenal(HNE) modified proteins are closely associated with cellular dysfunctions and biological metabolic process. The amount of such modified proteins is critical for ascertaining cell signalling pathways. The HNE-modified proteins are devoid of quantitative information, albeit comprehensive identification acquired from mass spectrometry(MS) analysis. Previous work commonly utilized the interplay between HNEprotein derived biotin-hydrazide and avidin-based matrices for enrichment, which pave the way to pinpoint the number of HNE adducts. Recently, innovative work has offered an indirectly chemoproteomic strategy to quantify lipid-derived electrophiles(LDEs);the globally quantitative, site-specific information of LDEs modified cysteine was first disclosed by competitive activity–based protein profiling(ABPP) strategy.1 But the ABPP strategy limits the detection of HNE adducts of histidine, lysine, and arginine. To supersede the cysteine-specific probe, latter work treated intact cells with the alkynyl analog of HNE(a HNE) but failed to point out the endogenous HNE modifications.3 In our earlier work, the aminoxy probe was first cited to enrich HNE-modified proteins and successfully applied in MCF-7 cells, emphasizing the highest efficiency with "click" time.3 Furthermore, we validated the quantitative HNE modifications through(multiple reaction monitoring) MRM-MS and five modification sites were successfully verified. To achieve the quantitation information, we invited a chemical labeling reagent and collectively quantified over 2000 HNE-modified peptides corresponding to more than 1000 proteins. Finally, we applied it into native cell proteomes and over 30 endogenous HNE-modified proteins were identified.

Denoising(DN) and demosaicing(DM) are the first crucial stages in the image signal processing pipeline. Recently, researches pay more attention to solve DN and DM in a joint manner, which is an extremely undetermined inverse problem. Existing deep learning methods learn the desired prior on synthetic dataset, which limits the generalization of learned network to the real world data. Moreover, existing methods mainly focus on the raw data property of high green information sampling rate for DM, but occasionally exploit the high intensity and signalto-noise(SNR) of green channel. In this work, a deep guided attention network(DGAN) is presented for real image joint DN and DM(JDD), which considers both high SNR and high sampling rate of green information for DN and DM, respectively. To ease the training and fully exploit the data property of green channel, we first train DN and DM sub-networks sequentially and then learn them jointly, which can alleviate the error accumulation. Besides, in order to support the real image JDD, we collect paired raw clean RGB and noisy mosaic images to conduct a realistic dataset. The experimental results on real JDD dataset show the presented approach performs better than the state-of-the-art methods, in terms of both quantitative metrics and qualitative visualization.
