| 1 | Controllable photonic spin Hall effect with phase function construction显示文摘Photonic spin Hall efect(SHE)provides new opportunities for achieving spin-based photonics applications.However,flexibly manipulating the spin-dependent sltting(SDS)of photonic SHE and imposing extra phase modulation on the two spin components are always a challenge.Here,a controllable SHE mechanism based on phase function construction is reported.It is conduded that the phases with specific functional structures performing a coordinate translation are equivalent to integrating a gradient phase to the original phases.Hence,the original phase can be used for independent phase modulation,and the gradient phase originating from the co-ordinate translation is capable of manipulating the SDS.A metasurface with Pancharatnam-Berry phase that can impose conjugate phases to the two spin components of light is fabricated to verify this mechanism.By shifing the light position,the SDS is continuously manipulated in the visible region,which is successfully used for detecting the polarization llipticity.The extra phase modulation is also performed with the original phase and thus enables measuring singular beams.It is anticipated that the controllable SHE manipulation method may open new avenues in the fields of spin photonics,optical sensing,optical communications,etc. | YANLIANG HE ZHIQIANG XIE BO YANG XUEYU CHEN JUNMIN LIU HUAPENG YE XINXING ZHOU YING LI SHUQING CHEN DIANYUAN FAN | 2020 | Photonics Research2020,8,6: | 3 |
| 2 | Restoring the dampened expression of the core clock molecule BMAL1 protects against compression-induced intervertebral disc degeneration显示文摘The circadian clock participates in maintaining homeostasis in peripheral tissues,including intervertebral discs(IVDs).Abnormal mechanical loading is a known risk factor for intervertebral disc degeneration(IDD).Based on the rhythmic daily loading pattern of rest and activity,we hypothesized that abnormal mechanical loading could dampen the IVD clock,contributing to IDD.Here,we investigated the effects of abnormal loading on the IVD clock and aimed to inhibit compression-induced IDD by targeting the core clock molecule brain and muscle Arnt-like protein-1(BMAL1).In this study,we showed that BMAL1 KO mice exhibit radiographic features similar to those of human IDD and that BMAL1 expression was negatively correlated with IDD severity by systematic analysis based on 149 human IVD samples.The intrinsic circadian clock in the IVD was dampened by excessive loading,and BMAL1 overexpression by lentivirus attenuated compression-induced IDD.Inhibition of the RhoA/ROCK pathway by Y-27632 or melatonin attenuated the compression-induced decrease in BMAL1 expression.Finally,the two drugs partially restored BMAL1 expression and alleviated IDD in a diurnal compression model.Our results first show that excessive loading dampens the circadian clock of nucleus pulposus tissues via the RhoA/ROCK pathway,the inhibition of which potentially protects against compression-induced IDD by preserving BMAL1 expression.These findings underline the importance of the circadian clock for IVD homeostasis and provide a potentially effective therapeutic strategy for IDD. | Dong Wang Pandi Peng Michal Dudek Xueyu Hu Xiaolong Xu Qiliang Shang Di Wang Haoruo Jia Han Wang Bo Gao Chao Zheng Jianxin Mao Chu Gao Xin He Pengzhen Cheng Huanbo Wang Jianmin Zheng Judith A.Hoyland Qing-Jun Meng Zhuojing Luo Liu Yang | 2022 | Bone Research2022,10,2: | 2 |

| 6 | Genome resequencing reveals the evolutionary history of garlic reproduction traits显示文摘The propagation of cultivated garlic relies on vegetative cloves,thus flowers become non-essential for reproduction in this species,driving the evolution of reproductive feature-derived traits.To obtain insights into the evolutionary alteration of reproductive traits in the clonally propagated garlic,the evolutionary histories of two main reproduction-related traits,bolting and flower differentiation,were explored by genome analyses using 134 accessions displaying wide diversity in these two traits.Resequencing identified 272.8 million variations in the garlic genome,198.0million of which represent novel variants.Population analysis identified five garlic groups that have evolved into two clades.Gene expression,single-cell transcriptome sequencing,and genome-wide trait association analyses have identified numerous candidates that correlate with reproductive transition and flower development,some of which display distinct selection signatures.Selective forces acting on the B-box zinc finger protein-encoding Asa2G00291.1,the global transcription factor group E protein-encoding Asa5G01527.1,and VERNALIZATION INSENSITIVE 3-like Asa3G03399.1 appear to be representative of the evolution of garlic bolting.Plenty of novel genomic variations and trait-related candidates represent valuable resources for biological studies of garlic.Numerous selective signatures from genes associated with the two chosen reproductive traits provide important insights into the evolutionary history of reproduction in this clonally propagated crop. | Haiping Wang Einat Shemesh-Mayer Jiangjiang Zhang Song Gao Zheng Zeng Zemao Yang Xueyu Zhang Huixia Jia Yanzhou Wang Jiangping Song Xiaohui Zhang Wenlong Yang Qiaoyun He Amir Sherman Lin Li Rina Kamenetsky Touming Liu | 2023 | Horticulture Research2023,10,11: | 0 |
| 7 | An Underwater Target Detection Algorithm Based on Attention Mechanism and Improved YOLOv7显示文摘For underwater robots in the process of performing target detection tasks,the color distortion and the uneven quality of underwater images lead to great difficulties in the feature extraction process of the model,which is prone to issues like error detection,omission detection,and poor accuracy.Therefore,this paper proposed the CER-YOLOv7(CBAM-EIOU-RepVGG-YOLOv7)underwater target detection algorithm.To improve the algorithm’s capability to retain valid features from both spatial and channel perspectives during the feature extraction phase,we have added a Convolutional Block Attention Module(CBAM)to the backbone network.The Reparameterization Visual Geometry Group(RepVGG)module is inserted into the backbone to improve the training and inference capabilities.The Efficient Intersection over Union(EIoU)loss is also used as the localization loss function,which reduces the error detection rate and missed detection rate of the algorithm.The experimental results of the CER-YOLOv7 algorithm on the UPRC(Underwater Robot Prototype Competition)dataset show that the mAP(mean Average Precision)score of the algorithm is 86.1%,which is a 2.2%improvement compared to the YOLOv7.The feasibility and validity of the CER-YOLOv7 are proved through ablation and comparison experiments,and it is more suitable for underwater target detection. | Liqiu Ren Zhanying Li Xueyu He Lingyan Kong Yinghao Zhang | 2024 | Computers, Materials & Continua2024,78,2: | 0 |

| 9 | Size effect enabling additive-free MXene ink with ultrahigh conductivity for screen printing of wireless electronics显示文摘Facile preparation of additive-free inks with both high viscosity and high conductivity is critical for scalable screen printing of wireless electronics,yet very challenging.MXene materials exhibit excellent conductivity and hydrophilicity,showing great potential in the field of additive-free inks for screen printing.Here,we demonstrate the synthesis of additive-free two-dimensional(2D)titanium carbide MXene inks,and realize screen-printed MXene wireless electronics for the first time.The viscosity of MXene ink is solely regulated by tuning the size of MXene nanosheet without any additives,hence rendering the printed MXene film extremely high conductivity of 1.67×10^(5) S/m and fine printing resolution down to 0.05 mm on various flexible substrates.Moreover,radio frequency identification(RFID)tags fabricated using the additive-free MXene ink via screen printing exhibit stable antenna reading performance and superb flexibility.This article,thus offers a new route for the efficient,low-cost and pollution-free manufacture of printable electronics based on additive-free MXene inks. | Shuaishuai Chen Huaqiang Fu Yunfa Si Xueyu Liu Zhe Wang Yixue Duan Zixin Zhang Hao Feng Xin Zhao Daping He | 2023 | Nano Research2023,16,8: | 0 |
| 10 | Engineering G-quadruplex aptamer to modulate its binding specificity显示文摘The use of aptamers in bioanalytical and biomedical applications exploits their ability to recognize cell surface protein receptors.Targeted therapeutics and theranostics come to mind in this regard.However,protein receptors occur on both cancer and normal cells;as such,aptamers are now taxed with identifying high vs.low levels of protein expression.Inspired by the flexible template mechanism and elegant control of natural nucleic acid-based structures,we report an allosteric regulation strategy for constructing a structure-switching aptamer for enhanced target cell recognition by engineering aptamers with DNA intercalated motifs(i-motifs)responsive to the microenvironment,such as p H.Structure-switching sensitivity can be readily tuned by manipulating i-motif sequences.However,structure-switching sensitivity is difficult to estimate,making it equally difficult to effectively screen modified aptamers with the desired sensitivity.To address this problem,we selected a fluorescent probe capable of detecting G-quadruplex in complicated biological media. | Long Li Shujuan Xu Xueyu Peng Yuzhuo Ji He Yan Cheng Cui Xiaowei Li Xiaoshu Pan Lu Yang Liping Qiu Jianhui Jiang Weihong Tan | 2021 | National Science Review2021,8,4: | 0 |
