| 1 | 基于优化Transformer网络的绿色目标果实高效检测模型显示文摘果园环境中,检测目标果实易受复杂背景、果实姿态和颜色等因素影响,为提高绿色目标果实检测的精度与效率,满足果园智能测产和自动化采摘要求,本研究针对不同光照环境和果实姿态,提出一种适于样本数量不足的绿色目标果实高效检测模型。该模型采用优化Transformer结构,首先借助卷积神经网络(Convolutional Neural Network,CNN)网络提取图像特征;然后输入编码-解码器生成一组目标果实预测框,最后通过前馈神经网络(Feed-forward Network,FFN)结构预测检测结果。在训练过程中,引入重采样法扩充样本数量,解决样本数量不足问题;引入迁移学习,加速网络收敛。分别制作苹果、柿子数据集用于模型训练。试验结果表明,经迁移学习后该模型训练效率大幅提高;与流行的目标检测模型相比,优化后的模型在检测绿色柿子与绿色苹果时,精度分别为93.27%和91.35%。该方法可为其他果蔬绿色目标检测提供理论借鉴。 | 贾伟宽 孟虎 马晓慧 赵艳娜 Ji Ze 郑元杰 | 2021 | 农业工程学报2021，37，14： | 13 |

| 5 | Dynamic Airy imaging through high_efficiency broadband phase microelements by femtosecond laser direct writing显示文摘Manipulating Airy beams to symmetric Airy beams(SABs)with abruptly autofocusing and self accelerating properties has attracted much attention.With such a particular propagation dynamic,SABs may provide great potential in dynamic signal imaging.On the other hand,the generation of SABs by spatial light modulators suffers from the limitations of phase gradient accuracy,low optical efficiency(<40%),and a bulky footprint.Therefore,exploring imaging applications and optimal generation methods of these Airy-type beams deserves further research.Here,based on the coordinate transformation of SAB,an asymmetric Airy beam(AAB)is realized.Symmetric/asymmetric cubic phase microplates(SCPPs/ACPPs)are designed and fabricated for generating SAB/AAB.The SCPP/ACPP demonstrates superior performance:compact construction(60μm × 60μm × 1.1μm),continuous variation of phase,high efficiency(~81%at 532 nm),and broadband operation from 405 to 780 nm.Dynamic imaging under monochromatic and polychromatic lights is realized by the SAB/AAB,indicating various results at different propagation distances with a certain initial signal.Further investigation reveals that the SCPP on a soft substrate maintains its physical dimensions and optical properties unchanged during stretching.Our work enables wide potential applications in integrated optics,beam manipulation,and imaging. | ZE CAI XINBO QI DENG PAN SHENGYUN JI JINCHENG NI ZHAOXIN LAO CHEN XIN JIAWEN LI YANLEI HU DONG Wu JIARU CHI | 2020 | Photonics Research2020，8，6： | 3 |
| 6 | Optimal Waist Circumference Cut-off values for Identifying Metabolic Risk Factors in Middle-aged and Elderly Subjects in Shandong Province of China显示文摘Objective To study the optimal waist circumference(WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China. Methods A total of 2 873 men and 5 559 women were included in this cross-sectional study. Metabolic syndrome(MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004. The relation between WC and MetS was analyzed by multivariate logistic regression analysis. The optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared. Results The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off value was 83.8 cm and 91.1 cm for identifying MetS in women and men, respectively. Compared with 80 cm and 85 cm for women and men, 85 cm and 90 cm had a higher Youden index for identifying all metabolic risk factors and MetS in women and men. Conclusion The appropriate WC cut-off value is 85 cm and 90 cm for identifying central obesity and MetS in women and men in Shandong Province of China. | HOU Xin Guo WANG Chuan MA Ze Qiang YANG Wei Fang WANG Ji Xiang LI Cheng Qiao WANG Yu Lian LIU Shu Min Hu Xiu Ping ZHANG Xiu Ping JIANG Mei WANG Wei Qing NING Guang ZHENG Hui Zhen MA Ai Xia SUN Yu SONG Jun LIN Peng LIANG Kai LIU Fu Qiang LI Wen Juan XIAO Juan GONG Lei WANG Mei Jian LIU Ji Dong YAN Fei YANG Jun Peng WANG Ling Shu TIAN Meng ZHAO Ru Xing JIANG Ling CHEN Li | 2014 | Biomedical and Environmental Sciences2014，27，5： | 3 |

| 8 | Occurrence and characteristics of sporadic K layer observed by lidar over Beijing, China显示文摘A double-laser-beam lidar was successfully developed in 2010 to measure the K layer over Yanqing County, Beijing(40.5°N, 116.2°E). Comprehensive statistical analyses of sporadic K(Ks) layer parameters were conducted using two years of lidar data, and the parameters of the Ks layers and their distribution obtained by the analyses are described. The seasonal distribution of Ks occurrence was obtained, with two maxima observed in January and July, respectively. The seasonal distributions of sporadic E(Es) occurrence over Beijing differ from those of Ks occurrence. However, good correlations between Es and Ks in case by case study were found. We also found that four Ks events with peak altitudes lower than 90 km were associated with large and sharp temperature increases in five comparative examples. | JIAO Jing YANG Guo Tao WANG Ji Hong WANG Ze Long YANG Yong | 2016 | Science China Earth Sciences2016，59，3： | 2 |

| 14 | Boosting the polysulfide confinement in B/N–codoped hierarchically porous carbon nanosheets via Lewis acid–base interaction for stable Li–S batteries显示文摘Carbon materials have shown remarkable usefulness in facilitating the performance of insulating sulfur cathode for lithium–sulfur batteries owing to their excellent conductivity and porous structure. However,the anxiety is the poor affinity toward polar polysulfides due to the intrinsic nonpolar surface of carbon.Herein, we report a direct pyrolysis of the mixture urea and boric acid to synthesize B/N–codoped hierarchically porous carbon nanosheets(B–N–CSs) as efficient sulfur host for lithium–sulfur battery. The graphene–like B–N–CSs provides high specific surface area and porous structure with abundant micropores(1.1 nm) and low–range mesopores(2.3 nm), thereby constraining the sulfur active materials within the pores. More importantly, the codoped B/N elements can further enhance the polysulfide confinement through strong Li–N and B–S interaction based on the Lewis acid–base theory. These structural superiorities significantly suppress the shuttle effect by both physical confinement and chemical interaction, and promote the redox kinetics of polysulfide conversion. When evaluated as the cathode host, the S/B–N–CSs composite displays the excellent performance with a high reversible capacity up to 772 m A h g–1 at 0.5 C and a low fading rate of ^0.09% per cycle averaged upon 500 cycles. In particular, remarkable stability with a high capacity retention of 87.1% can be realized when augmenting the sulfur loading in the cathode up to 4.6 mg cm^(-2). | Dong-Gen Xiong Ze Zhang Xiao-Yun Huang Yan Huang Ji Yu Jian-Xin Cai Zhen-Yu Yang | 2020 | Journal of Energy Chemistry2020，29，12： | 1 |

| 17 | Isotoosendanin exerts inhibition on triple-negative breast cancer through abrogating TGF-β-induced epithelial—mesenchymal transition via directly targeting TGFβR1显示文摘As the most aggressive breast cancer,triple-negative breast cancer(TNBC) is still incurable and very prone to metastasis.The transform growth factor β(TGF-β)-induced epithelial—mesenchymal transition(EMT) is crucially involved in the growth and metastasis of TNBC.This study reported that a natural compound isotoosendanin(ITSN) reduced TNBC metastasis by inhibiting TGF-β-induced EMT and the formation of invadopodia.ITSN can directly interact with TGF-β receptor type-1(TGFβR1) and abrogated the kinase activity of TGFβR1,thereby blocking the TGF-β-initiated downstream signaling pathway.Moreover,the ITSN-provided inhibition on metastasis obviously disappeared in TGFβR1-overexpressed TNBC cells in vitro as well as in mice bearing TNBC cells overexpressed TGFβR1.Furthermore,Lys232 and Asp351 residues in the kinase domain of TGFβR1 were found to be crucial for the interaction of ITSN with TGFβR1.Additionally,ITSN also improved the inhibitory efficacy of programmed cell death 1 ligand 1(PD-L1) antibody for TNBC in vivo via inhibiting the TGF-β-mediated EMT in the tumor microenvironment.Our findings not only highlight the key role of TGFβR1 in TNBC metastasis,but also provide a leading compound targeting TGFβR1 for the treatment of TNBC metastasis.Moreover,this study also points out a potential strategy for TNBC treatment by using the combined application of anti-PD-L1 with a TGFβR1 inhibitor. | Jingnan Zhang Ze Zhang Zhenlin Huang Manlin Li Fan Yang Zeqi Wu Qian Guo Xiyu Mei Bin Lu Changhong Wang Zhengtao Wang Lili Ji | 2023 | Acta Pharmaceutica Sinica B2023，13，7： | 1 |
| 18 | Characteristics of Gaseous Pollutants at a Regional Background Station in Southern China显示文摘Measurements of gaseous pollutants(O3, NOx, SO2, and CO) were conducted at Dinghushan background station in southern China from January to December 2013.The levels and variations of O3, NOx, SO2, and CO were analyzed and their possible causes discussed. The annual average concentrations of O3, NOx, SO2, and CO were 24.6 ± 23.9, 12.8 ± 10.2, 4.0 ± 4.8, and 348 ± 185 ppbv, respectively. The observed levels of the gaseous pollutants are comparable to those at other background sites in China. The most obvious diurnal variation of O3 was observed in autumn, with minima in the early morning and maxima in the afternoon. The diurnal variations of SO2 showed high values during the day. The diurnal cycles of NOx showed higher values in the morning and lower values during the night. Higher CO concentrations were observed in spring followed by winter, autumn, and summer. Biomass burning, in combination with the transport of regional pollution, is an important source of CO, SO2, and NOx in spring and winter. Backward trajectories were calculated and analyzed together with corresponding pollutant concentrations. The results indicate that air masses passing over polluted areas are responsible for the high concentrations of gaseous pollutants at the Dinghushan background station. | CHAO Na JI Dong-Sheng CHEN Jia-Shan XIN Jin-Yuan HU Bo WANG Yue-Si WANG Hui MENG Ze | 2014 | Atmospheric and Oceanic Science Letters2014，7，4： | 1 |
