| 1 | Bottom water temperature measurements in the South China Sea,eastern Indian Ocean and western Pacific Ocean显示文摘文章报道了一批新的海底底水温度(BWT)数据,其中南海(SCS)158个站位、东印度洋(EIO)30个站位及西太平洋(WPO)37个站位。基于这批新的BWT数据,获得南海和西太平洋海域底水温度与水深经验关系,可为地球物理和物理海洋提供准确、可靠的海底温度边界。这将有助于海底油气资源调查与评估。同时,这批实测数据表明:1)水深超过3500m的海域,其底水温度在南海约为2.47℃,比东印度洋(~1.34℃)和西太平洋(~1.60℃)稍微偏高。这与大洋传送带模式所预测的情况比较吻合。该模式认为:低温高盐的海水,从北大西洋格陵兰岛和冰岛附近海域下沉到深层,然后向南流动,再与南极洲周围海域的低温高盐海水一同向北进入印度洋和太平洋。而南海是一个相对比较封闭的热带边缘海,其内部海水与印度洋和菲律宾海交换有限,导致海水温度整体高于印度洋和太平洋。2)台西南盆地水深在2700~3000m的部分站位,其底水温高达约3.00℃,明显高于其周边同水深海域底水温度(平均值约为2.33℃)。这可能是台西南盆地海底水热活动导致的结果。3)在东印度洋和西太平洋水深超过4800m海域,底水温度随着水压增大稍有升高,其升高率分别为10.6mK·MPa^(-1)和12.0mK·MPa^(-1)。这与理论估算的深层底水绝热压力温度梯度范围较为吻合。这也意味着东印度洋和西太平洋深层底水,主要由绝热自压作用导致其温度随着深度的增大而升高。 | YANG Xiaoqiu SHI Xiaobin ZHAO Junfeng YU Chuanhai GAO Hongfang CHEN Aihua LU Yuanzheng CEN Xianrong LIN Weiren ZENG Xin XU Hehua REN Ziqiang ZHOU Shengqi XU Ziying SUN Jinlong KAMIYA Nana LIN Jian | 2018 | 热带海洋学报2018,37,5: | 8 |
| 2 | Factors Affecting Cr(Ⅲ) Oxidation by Manganese Oxides显示文摘The high oxidation ability of manganese oxides or soils was used to study effects of pH and coatingon Cr(Ⅲ) oxidation. The results indicated that Cr(Ⅲ) oxidation peaked in pH 4.0-6.5. The amount andrate of Cr(Ⅲ) being oxidized by uncoated δ-MnO2 were larger than those by Fe oxide- or CaCO3-coatedone. Inorganic Cr(Ⅲ) was more easi1y oxidized by MnO2 than organic complex Cr(Ⅲ) due to differentsurface affinities. Precipitated Cr(Ⅲ) and adsorbed Cr(Ⅲ) might be transferred onto MnO2 surface andthen oxidized to Cr(VI). | CHEN YINGXU CHEN YIYI LIN QI HU ZIQIANG HU HONG and WU JIANYANG(Dept. of Environ.

| 3 | Research progress in electrospinning engineering for all-solid-state electrolytes of lithium metal batteries显示文摘Owing to safety issue and low energy density of liquid lithium-ion batteries(LIBs),all-solid-state lithium metal batteries(ASLMBs)with unique all-solid-state electrolytes(SEs)have attracted wide attentions.This arises mainly from the advantages of the SEs in the suppression of lithium dendrite growth,long cycle life,and broad working temperature range,showing huge potential applications in electronic devices,electric vehicles,smart grids,and biomedical devices.However,SEs suffer from low lithiumion conductivity and low mechanical integrity,slowing down the development of practical ASLMBs.Nanostructure engineering is of great efficiency in tuning the structure and composition of the SEs with improved lithium-ion conductivity and mechanical integrity.Among various available technologies for nanostructure engineering,electrospinning is a promising technique because of its simple operation,cost-effectiveness,and efficient integration with different components.In this review,we will first give a simple description of the electrospinning process.Then,the use of electrospinning technique in the synthesis of various SEs is summarized,for example,organic nanofibrous matrix,organic/inorganic nanofibrous matrix,and inorganic nanofibrous matrix combined with other components.The current development of the advanced architectures of SEs through electrospinning technology is also presented to provide references and ideas for designing high-performance ASLMBs.Finally,an outlook and further challenges in the preparation of advanced SEs for ASLMBs through electrospinning engineering are given. | Manxi Wang Yaling Wu Min Qiu Xuan Li Chuanping Li Ruiling Li Jiabo He Ganggang Lin Qingrong Qian Zhenhai Wen Xiaoyan Li Ziqiang Wang Qi Chen Qinghua Chen Jinhyuk Lee Yiu-Wing Mai Yuming Chen | 2021 | Journal of Energy Chemistry2021,30,10: | 4 |

| 5 | Ten-year Follow-up of Familial Nanophthalmos in Three Siblings显示文摘Purpose: Nanophthalmos is a rare congenital disorder associated with a high incidence of angle-closure glaucoma..We followed the clinical manifestations of three siblings to evaluate their responses to various treatments.Methods:.Three sisters with nanophthalmos were followed from 2000 to 2013..Glaucoma and cataract treatments were performed whenever indicated.Results: The oldest sister had chronic elevation of intraocular pressure(IOP) and underwent laser peripheral iridotomy(LPI)on both eyes,.followed by uneventful phacoemulsification with intraocular lens(IOL) implantation on the left eye and phacotrabeculectomy with IOL implantation on the right eye.The middle sister had acute elevation of IOP and initially underwent phacoemulsification combined with implantation of two IOLs on her left eye and LPI on her right eye. Severe uveal effusion occurred when phacoemulsification was performed on her right eye 6 years later, but ultimately was completely resolved. In both sisters, stable IOP and visual results were achieved after lensectomy. The youngest sister, who had suspected angle-closure, achieved a stable IOP and visual results with prophylactic LPI alone.Conclusion: In nanophthalmic eyes, the severity of the disease may foreshadow the severity of surgical complications and responses to therapy. | Jingjing Huang Yunlan Ling Mingkai Lin Ziqiang Wu Bing Cheng Jian Ge | 2013 | Eye Science2013,28,3: | 1 |
| 6 | Enhanced N_(2)-to-NH_(3)conversion efficiency on Cu3P nanoribbon electrocatalyst显示文摘Ambient electroreduction of nitrogen(N_(2))is considered as a green and feasible approach for ammonia(NH_(3))synthesis,which urgently demands for efficient electrocatalyst.Morphology has close relationship with catalytic activity of heterogeneous catalysts.Nanoribbon is attractive nanostructure,which possesses the flexibility of one-dimensional nanomaterials,the large surface area of two-dimensional nanomaterials,and lateral size confinement effects.In this work,Cu_(3)P nanoribbon is proposed as a highly efficient electrocatalyst for N_(2)-to-NH_(3)conversion under benign conditions.When measured in N_(2)-saturated 0.1 M HCl,such Cu_(3)P nanoribbon achieves high performance with an excellent Faradaic efficiency as high as 37.8%and a large yield of 18.9μg·h^(−1)·mgcat.−1 at−0.2 V.It also demonstrates outstanding stability in long-term electrolysis test at least for 45 h. | Qian Liu Yiting Lin Shuang Gu Ziqiang Cheng Lisi Xie Shengjun Sun Longcheng Zhang Yongsong Luo Abdulmohsen Ali Alshehri Mohamed SHamdy Qingquan Kong Jiahong Wang Xuping Sun | 2022 | Nano Research2022,15,8: | 1 |
| 7 | Refined model analysis of basement rock degradation mechanism of heavy-haul railway tunnel显示文摘This study investigated the degradation mechanism of the surrounding rock of a heavy-haul railway under a water-rich condition,based on the construction of the Taihangshan tunnel for the Wari Railway,a heavy-haul railway that used standard construction practices for axle loads of 30 t.Remote monitoring demonstrated that the coupling effect between the dynamic load of a heavy-haul train and the groundwater leads to the deterioration and hollowing of the surrounding rock.This study clarified the void evolution process and deterioration mechanism of the basement rock under the comprehensive influence of the groundwater–train dynamic load using a refined discrete element numerical simulation.The results revealed that the groundwater was the primary influencing factor in the deterioration of the lower part of the heavy-haul railway tunnel.Rock particles were gradually lost under the effects of long-term erosion due to groundwater and heavy-haul trains,which inevitably damaged the basement rock after the construction was completed.Based on this observation,the critical conditions for the deterioration and attenuation law of the physical parameters of the basement rock were obtained.The results of this study can provide ideas and serve as a reference for the forecasting and disaster treatment of basement rock damage in heavy-haul railway tunnels. | Zheng Li Ziqiang Li Ruyi Cai Yang Hua Lin Wang Dongming Gu | 2021 | Underground Space2021,6,3: | 1 |
| 8 | Facing small and biased data dilemma in drug discovery with enhanced federated learning approaches显示文摘Artificial intelligence(AI)models usually require large amounts of high-quality training data,which is in striking contrast to the situation of small and biased data faced by current drug discovery pipelines.The concept of federated learning has been proposed to utilize distributed data from different sources without leaking sensitive information of the data.This emerging decentralized machine learning paradigm is expected to dramatically improve the success rate of AI-powered drug discovery.Here,we simulated the federated learning process with different property and activity datasets from different sources,among which overlapping molecules with high or low biases exist in the recorded values.Beyond the benefit of gaining more data,we also demonstrated that federated training has a regularization effect superior to centralized training on the pooled datasets with high biases.Moreover,different network architectures for clients and aggregation algorithms for coordinators have been compared on the performance of federated learning,where personalized federated learning shows promising results.Our work demonstrates the applicability of federated learning in predicting drug-related properties and highlights its promising role in addressing the small and biased data dilemma in drug discovery. | Zhaoping Xiong Ziqiang Cheng Xinyuan Lin Chi Xu Xiaohong Liu Dingyan Wang Xiaomin Luo Yong Zhang Hualiang Jiang Nan Qiao Mingyue Zheng | 2022 | Science China(Life Sciences)2022,65,3: | 1 |

| 10 | PIF4 and HOOKLESS1 Impinge on Common Transcriptome and Isoform Regulation in Thermomorphogenesis显示文摘High temperature activates the transcription factor PHYTOCHROME-INTERACTING FACTOR4(PIF4)to stimulate auxin signaling,which causes hypocotyl elongation and leaf hyponasty(thermomorphogenesis).HOOKLESS1(HLS1)is a recently reported positive regulator of thermomorphogenesis,but the molecular mechanisms by which HLS1 regulates thermomorphogenesis remain unknown.In this study,we initially compared PIF4-and/or HLS1-dependent differential gene expression(DEG)upon high-temperature treatment.We found that a large number of genes are coregulated by PIF4 and HLS1,especially genes involved in plant growth or defense responses.Moreover,we found that HLS1 interacts with PIF4 to form a regulatory module and that,among the HLS1-PIF4-coregulated genes,27.7%are direct targets of PIF4.We also identified 870 differentially alternatively spliced genes(DASGs)in wild-type plants under high temperature.Interestingly,more than half of these DASG events(52.4%)are dependent on both HLS1 and PIF4,and the spliceosome-defective mutant plantsexhibit a hyposensitive response to high temperature,indicating that DASGs are required for thermomorphogenesis.Further comparative analyses showed that the HLS1/PIF4-coregulated DEGs and DASGs exhibit almost no overlap,suggesting that high temperature triggers two distinct strategies to control plant responses and thermomorphogenesis.Taken together,these results demonstrate that the HLS1-PIF4 module precisely controls both transcriptional and posttranscriptional regulation during plant thermomorphogenesis. | Huanhuan Jin Jingya Lin Ziqiang Zhu | 2020 | Plant Communications2020,1,2: | 1 |

| 12 | The As-surface of an iron-based superconductor CaKFe_(4)As_(4)显示文摘As a new type of iron-based superconductor, CaKFe_(4)As_(4) has recently been demonstrated to be a promising platform for observing Majorana zero modes (MZMs). The surface of CaKFe_(4)As_(4) plays an important role in realizing the MZM since it hosts superconducting topological surface states. However, due to the complicated crystal structure, the terminal surface of CaKFe_(4)As_(4) has not been determined yet. Here, by using scanning tunneling microscopy/spectroscopy (STM/S), we find that there are two types of surface structure in CaKFe_(4)As_(4). Bias-dependent atomic resolution images show an evolvement from 2–√×2–√ superstructure with respect to the As lattice into 1 × 1 when the tip is brought close to the surface, revealing the sublattice of missing As atoms. Together with the first-principles calculations, we show that the surface As layer has a buckled structure. Our findings provide insight to future surface study of CaKFe_(4)As_(4) as well as other iron-pnictide superconductors. | Lu Cao Yang Song Ya-Bin Liu Qi Zheng Guangyuan Han Wenyao Liu Meng Li Hui Chen Yuqing Xing Guang-Han Cao Hong Ding Xiao Lin Shixuan Du Yu-Yang Zhang Geng Li Ziqiang Wang Hong-Jun Gao | 2021 | Nano Research2021,14,11: | 1 |
| 13 | Effectiveness of COVID-19 Vaccination Against SARS-CoV-2 Omicron Variant Infection and Symptoms—China,December 2022–February 2023显示文摘Summary What is already known about this topic?A considerable percentage of the population has received both primary and booster vaccinations,which could potentially provide protection against severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)Omicron infections and related symptoms.What is added by this report?The self-reported infection rate,as determined from an online survey,reached its peak(15.5%)between December 19 and 21,2022,with an estimated 82.4%of individuals in China being infected as of February 7,2023.During the epidemic,the effectiveness of booster vaccinations against SARS-CoV-2 Omicron infection was found to be 49.0%within three months of vaccination and 37.9%between 3 and 6 months following vaccination.Furthermore,the vaccine effectiveness of the booster vaccination in relation to symptom prevention varied from 48.7%to 83.2%within three months and from 25.9%to 69.0%between 3 and 6 months post-booster vaccination. | Di Fu Guanhao He Huanlong Li Haomin Tan Xiaohui Ji Ziqiang Lin Jianxiong Hu Tao Liu Jianpeng Xiao Xiaofeng Liang Wenjun Ma | 2023 | China CDC weekly2023,5,17: | 0 |
| 14 | Interlayer and doping engineering in partially graphitic hollow carbon nanospheres for fast sodium and potassium storage显示文摘Constructing anodes with fast ions/electrons transfer paths is an effective strategy to achieve high-performance sodium ion batteries(SIBs)/potassium ion batteries(PIBs). Amorphous carbon is a promising candidate anode for SIBs/PIBs owing to its disordered carbon layers, abundant defects/pores, and lowcost resources. However, the larger radius of Na^(+)/K^(+) leading to depressed kinetics and poor cycling performance, impeding their further applications. Herein, we propose an efficient strategy to construct of nitrogen, sulfur co-doped hollow carbon nanospheres(NS-HCS) involving an in situ growth of polydopamine on nano-Ni(OH)2template with subsequent sulfur doping process. During the formation process, the produced Ni nanospheres play as the hard template and catalyst for the formation of hollow carbon nanosphere with partially graphite microcrystalline structure, while the sulfur doping process can enlarge the interlayer space and create more defects on the surface of carbon nanospheres, thus synchronous improve the Na^(+)/K^(+) insertion and adsorption ability in NS-HCS. With the synergistic control of the enlarged interlayer spacing, high content of pyridinic N/pyrrolic N and graphitization, a hybrid storage mechanism facilitates the transport kinetics and endows the NS-HCS electrode with high capacities and good cycling stability in SIBs and PIB. Benefit from the multiple effects, NS-HCS exhibits the improved capacity of 274.8 m Ah/g at 0.1 A/g and excellent cycling stability of 149.5 m Ah/g after 5000 cycles at2.5A/g in SIBs, as well as good potassium ion storage behavior with a high capacity retention of 76.5%after 700 cycles at 1.0 A/g, demonstrating the potential applications of NS-HCS for high-performance SIBs and PIBs. | Dongfei Sun Sen Lin Dandan Yu Zijuan Wang Fangfang Deng Xiaozhong Zhou Guofu Ma Ziqiang Lei | 2023 | Chinese Chemical Letters2023,34,2: | 0 |
| 15 | Rice sl-MH-1 mutant induces cell death and confers blast resistance via the synergistic roles of signaling systems显示文摘Serotonin is ubiquitous across all forms of life and functions in responses to biotic and abiotic stresses.In rice,the conversion of tryptamine to serotonin is catalyzed by Sekiguchi lesion(SL).Previous studies have identified an sl mutation(a null mutation of SL)in several rice varieties and confirmed its increase of resistance and cell death.However,a systematic understanding of the reprogrammed cellular processes causing cell death and resistance is lacking.We performed a multi-omics analysis to clarify the fundamental mechanisms at the protein,gene transcript,and metabolite levels.We found that cell death and Magnaporthe oryzae(M.oryzae)infection of the sl-MH-1 mutant activated plant hormone signal transduction involving salicylic acid(SA),jasmonic acid(JA),and abscisic acid(ABA)in multiple regulatory layers.We characterized the dynamic changes of several key hormone levels during disease progression and under the cell death conditions and showed that SA and JA positively regulated rice cell death and disease resistance.SL-overexpressing lines confirmed that the sl-MH-1 mutant positively regulated rice resistance to M.oryzae.Our studies shed light on cell death and facilitate further mechanistic dissection of programmed cell death in rice. | Dagang Tian Yan Lin Shengping Li Yiyang Cao Gang Li Xinrui Guo Ziqiang Chen Zaijie Chen Feng Wang Zonghua Wang | 2022 | The Crop Journal2022,10,6: | 0 |

| 17 | When and How to Adjust Non-Pharmacological Interventions Concurrent with Booster Vaccinations Against COVID-19—Guangdong,China,2022显示文摘Introduction:With the large-scale roll-out of the coronavirus disease 2019(COVID-19)booster vaccination effort(a vaccine dose given 6 months after completing primary vaccination)in China,we explore when and how China could lift non-pharmacological interventions(NPIs)against COVID-19 in 2022.Methods:Using a modified susceptible-infectiousrecovered(SIR)mathematical model,we projected the COVID-19 epidemic situation and required medical resources in Guangdong Province,China.Results:If the number of people entering from overseas recovers to 20%of the number in 2019,the epidemic in 2022 could be controlled at a low level by a containment(215 local cases)or suppression strategy(1,397 local cases).A mitigation strategy would lead to 21,722 local cases.A coexistence strategy would lead to a large epidemic with 6,850,083 local cases that would overwhelm Guangdong’s medical system.With 50%or 100%recovery of the 2019 level of travelers from overseas,the epidemic could also be controlled with containment or suppression,but enormous resources,including more hotel rooms for border quarantine,will be required.However,coexistence would lead to an uncontrollable epidemic with 12,922,032 local cases.Discussion:With booster vaccinations,the number of travelers from overseas could increase slightly in 2022,but a suppression strategy would need to be maintained to ensure a controllable epidemic. | Guanhao He Fangfang Zeng Jianpeng Xiao Jianguo Zhao Tao Liu Jianxiong Hu Sicong Zhang Ziqiang Lin Huaiping Zhu Dan Liu Min Kang Haojie Zhong Yan Li Limei Sun Yuwei Yang Zhixing Li Zuhua Rong Weilin Zeng Xing Li Zhihua Zhu Xiaofeng Liang Wenjun Ma | 2022 | China CDC weekly2022,4,10: | 0 |
| 18 | Design and comparative analysis of self-propelling drill bit applied to deep-sea stratum drilling robot显示文摘Robotic subsea stratum drilling robot is a method for new subsea stratigraphic geological investigation and resource exploration.Resistance at the front end is the main source of resistance to the robot’s motion in the strata.Since there is no continuous and strong downward drilling force as in conventional drilling rigs,robot movement relies heavily on the drill bit to reduce the drilling resistance.In this study we propose a self-propelling drill bit that can discharge soil debris to provide propulsive force and reduce the resistance.The key parameter of the drill bit design,the spiral blade lead angle,was determined by theoretical analysis of the drill bit’s soil discharging effect.To verify the structural advantages of the self-propelling drill bit in reducing resistance,a comparative analysis with a conventional conical drill bit was conducted.The drilling process of both bits was simulated using finite element simulation at various rotation speeds,the penetration force and torque data of both drill bits were obtained,and tests prepared accordingly in subsea soil were conducted.The simulations and tests verified that the penetration force of the self-propelling drill bit was lower than that of the conventional conical drill bit.The self-propelling drill bit can reduce the resistance effectively,and may play an important role in the stratum movement of drilling robots. | Peihao ZHANG Xingshuang LIN Hao WANG Jiawang CHEN Zhenwei TIAN Zixin WENG Ziqiang REN Peng ZHOU | 2023 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2023,24,10: | 0 |
| 19 | Identifying and managing risks of AI-driven operations:A case study of automatic speech recognition for improving air traffic safety显示文摘In this work,the primary focus is to identify potential technical risks of Artificial Intel-ligence(AI)-driven operations for the safety monitoring of the air traffic from the perspective of speech communication by studying the representative case and evaluating user experience.The case study is performed to evaluate the AI-driven techniques and applications using objective metrics,in which several risks and technical facts are obtained to direct future research.Considering the safety–critical specificities of the air traffic control system,a comprehensive subjective evaluation is conducted to collect user experience by a well-designed anonymous questionnaire and a face-to-face interview.In this procedure,the potential risks obtained from the case study are confirmed,and the impacts on human working are considered.Both the case study and the evaluation of user experience provide compatible results and conclusions:(A)the proposed solution is promising to improve the traffic safety and reduce the workload by detecting potential risks in advance;(B)the AI-driven techniques and whole diagram are suggested to be enhanced to eliminate the possible distraction to the attention of air traffic controllers.Finally,a variety of strategies and approaches are discussed to explore their capability to advance the proposed solution to industrial practices. | Yi LIN Min RUAN Kunjie CAI Dan LI Ziqiang ZENG Fan LI Bo YANG | 2023 | Chinese Journal of Aeronautics2023,36,4: | 0 |
| 20 | AgAuSe quantum dots with absolute photoluminescence quantum yield of 87.2%:The effect of capping ligand chain length显示文摘Surface ligands of colloidal quantum dots(QDs)have a profound influence on their surface states,which has been verified in the studies of the effect of ligand head groups on the photoluminescence(PL)properties of QDs.However,the investigation of the ligand chain length is limited.Here,we systematically explored the effect of chain length on the Ag_(2)Se QDs by selecting three ligands,1-octanethiol(OTT),1-dodecanethiol(DDT),and 1-hexadecanethiol(HDT),with diverse chain lengths.We found that the PL intensity of Ag_(2)Se QDs increased with the decrease of the ligand chain length due to the enhanced passivation of surface defects emerging from the robust QD-ligand interface binding affinity and the weaker hydrophobic chain–chain interaction.Subsequently,AgAuSe QDs terminated with OTT were obtained by alloying parent OTT-Ag_(2)Se QDs with Au precursor with a record absolute PL quantum yield(PLQY)of 87.2%at 970 nm,facilitating ultrasensitive in vivo angiography imaging in a nude mouse model.We expect that our finding of the important role of the ligand chain length on the optical properties of QDs will be suggestive to the design and synthesis of high-quality QDs,and also look forward to the clinical applications of the ultra-bright AgAuSe QDs. | Ziqiang Sun Cheng Liu Hongchao Yang Xiaohu Yang Yejun Zhang Hongzhen Lin Youyong Li Qiangbin Wang | 2022 | Nano Research2022,15,9: | 0 |
