| 2 | Dynamics of the SARS-CoV-2 antibody response up to 10 months after infection显示文摘COVID-19 caused by SARS-CoV-2 infection has caused substantial morbidity and mortality worldwide and paralyzed the international economy.Understanding the magnitude and duration of the antibody response to SARS-CoV-2 is important to achieve a balance between curbing the pandemic and minimizing adverse effects on society.1 Although the antibody response to SARS-CoV-2 within 9 months has been extensively studied,2,3,4,5,6 little is known about the magnitude and kinetics of antibody responses for over 9 months.Moreover,with limited observations over 9 months(n<100),2,7,8 several studies have produced inconsistent conclusions about antibody dynamics,suggesting different rates of antiviral antibody positivity at the last follow-up.2,7,8 These studies have been limited by a lack of measurement of neutralizing antibodies(NAbs),7 of inclusion of mild or asymptomatic cases,2,8 and of further exploration of potential predisposing factors for antibody dynamics.2,7 Considering the individual heterogeneity(such as disease severity)8 and time-dependent nature1 of the immune response,in-depth characterization of SARS-CoV-2 antibody kinetics across disease severity groups over a long period is urgently needed.Therefore,we repeatedly tested IgM,IgG,viral spike protein receptor-binding dom(anti-RBD)IgG,and NAb titers in COVID-19 patients during a follow-up period of up to 10 months and explored potential predisposing factors of antibody titers during follow-up. | Hao Wang Yu Yuan Mingzhong Xiao Li Chen Youyun Zhao Haiwei Zhang Pinpin Long Yana Zhou Xi Xu Yanshou Lei Bihao Wu Tingyue Diao Hao Cai Li Liu Zuoyu Shao Jingzhi Wang Yansen Bai Kai Wang Miao Peng Linlin Liu Shi Han Fanghua Mei Kun Cai Yake Lei An Pan Chaolong Wang Rui Gong Xiaodong Li Tangchun Wu | 2021 | Cellular & Molecular Immunology2021，18，7： | 1 |
| 3 | An Overview of Organs-on-Chips Based on Deep Learning显示文摘Microfluidic-based organs-on-chips(OoCs)are a rapidly developing technology in biomedical and chemical research and have emerged as one of the most advanced and promising in vitro models.The miniaturization,stimulated tissue mechanical forces.and microenvironment of OoCs offer unique properties for biomedical applications.However,the large amount of data generated by the high parallelization of OoC systems has grown far beyond the scope of manual analysis by researchers with biomedical backgrounds.Deep learning,an emerging area of research in the field of machine learning,can automatically mine the inherent characteristics and laws of'big data'and has achieved remarkable applications in computer vision,speech recognition,and natural language processing.The integration of deep learning in OoCs is an emerging field that holds enormous potential for drug development,disease modeling,and personalized medicine.This review bricfly describes the basic concepts and mechanisms of microfluidics and deep learning and summarizes their successful integration.We then analyze thecombination of OoCs and deep learning for image digitization,data analysis,and automation.Finally,the problems faced in current applications are discussed,and future perspectives and suggestions are provided to further strengthen this integration. | Jintao Li Jie Chen Hua Bai Haiwei Wang Shiping Hao Yang Ding Bo Peng Jing Zhang Lin Li Wei Huang | 2022 | Research2022，，2： | 1 |
| 4 | Spatiotemporal Distribution of Asian Horseshoe Crab Eggs Are Highly Intermingled with Anthropogenic Structures in Northern Beibu Gulf,China显示文摘Identification,protection and restoration of spawning habitats are vital for protecting the depleted species.Asian horseshoe crabs are ecologically important macroinvertebrates in coastal and estuarine ecosystems.However,their spawning habitat studies were limited to several reports in tropical regions,possibly due to the lack of modified survey methods,particularly in habitats with a lower density of spawning adults,and/or intermingled with anthropogenic structures.In this study,the year-round egg distribution and spawning habitat baselines of Carcinoscorpius rotundicauda and Tachypleus tridentatus were determined in the northern Beibu Gulf,China.Our findings demonstrated that the peak spawning occurred in June–July and ceased in November–January when the average water temperature dropped below 20℃.Egg aggregations were found<10 cm beneath the sediment surface with regular tidal inundation,regardless of seasonal changes,in the vicinity of natural and artificial structures with elevated,mildly sloping substratum within the high tide zones.The nests were characterized by medium-sized sediment grains(0.5–0.9 mm),high temperatures(31–34℃),low water contents(0.8%–0.9%),and total organic carbon contents(0.5%–0.7%),which might maximize the hatching success.The identified nesting beaches were close to nursery habitats for juveniles,and tidal creeks were present as the possible corridor connecting these two important habitats through the dominant mangrove forests.The findings provide valuable insights in the scope of spawning behavior and nest-site selection of Asian horseshoe crabs under a mixture of natural and artificial structures,which could benefit future management efforts for the exploited spawning populations. | KWAN Kit Yue FU Yijian ZHONG Mufeng KUANG Yang BAI Haiwei ZHANG Ce ZHEN Wenquan XU Peng WANG Chun-Chieh ZHU Junhua | 2022 | Journal of Ocean University of China2022，21，3： | 1 |
| 5 | Study on high-order frequency selective surface with interdigital capacitance loading显示文摘The application of frequency selection surfaces(FSSs)is limited by large area,narrow bandwidth,low stopband inhibition and large ripple in the passband.A method for designing high-order wide band miniaturized-element frequency selective surface(MEFSS)with capacitance loading is introduced.The proposed structure is composed of multiply sub-wavelength interdigital capacitance layer,sub-wavelength inductive wire grids separated by dielectric substrates.A simple equivalent circuit model,composed of short transmission lines coupled together with shunt inductors and capacitors,is presented for this structure.Using the equivalent circuit model and electromagnetic(EM)model,an analytical synthesis procedure is developed that can be used to synthesize the MEFSS from its desired system-level performance indicators such as the center frequency of operation,bandwidth and stopband inhibition.Using this synthesis procedure,a prototype of the proposed MEFSS with a third-order bandpass response,center frequency of 2.75 GHz,fractional bandwidth of 8%is designed,fabricated,and measured.The measurement results confirm the theoretical predictions and the design procedure of the structure and demonstrate that the proposed MEFSS has a stable frequency response with respect to the angle of incidence of the EM wave in the±30°range incidence,and the in-band return loss is greater than 18 dB,and the rejection in the stopband is greater than 25 dB at the frequency of 3.2 GHz. | Zheng Guangming Zhou Tianle Lu Haiwei Long Yifei Bai Jing | 2024 | The Journal of China Universities of Posts and Telecommunications2024，31，1： | 0 |
