| 1 | Progress and Applications of Visual SLAM显示文摘Visual simultaneous localization and mapping (SLAM) provides mapping and self-localization results for a robot in an unknown environment based on visual sensors, that have the advantages of small volume, low power consumption, and richness of information acquisition. Visual SLAM is essential and plays a significant role in supporting automated and intelligent applications of robots. This paper presents the key techniques of visual SLAM, summarizes the current research status, and analyses the new trends of visual SLAM research and development. Finally, specific applications of visual SLAM in restricted environments, including deep space and indoor scenarios, are discussed. | Kaichang DI Wenhui WAN Hongying ZHAO Zhaoqin LIU Runzhi WANG Feizhou ZHANG | 2019 | Journal of Geodesy and Geoinformation Science2019，2，2： | 11 |
| 2 | Landing site topographic mapping and rover localization for Chang’e-4 mission显示文摘This paper presents the techniques and results of landing-site topographic mapping and rover localization using orbital,descent and rover images in the Chang’e-4 mission.High-resolution maps of the landing site are generated from orbital and descent images.Local digital elevation models and digital orthophoto maps with 0.02 m resolution are generated at each waypoint.The location of the lander is determined as(177.588?E,45.457?S)using festure-matching techniques.The cross-site visual localization method is routinely used to localize the rover at each waypoint to reduce error accumulation from wheel slippage and IMU drift in dead reckoning.After the first five lunar days,the rover travels 186.66 m from the lander,according to the cross-site visual localization.The developed methods and results have been directly utilized to support the mission’s operations.The maps and localization information are also valuable for supporting multiple scientific explorations of the landing site. | Zhaoqin LIU Kaichang DI Jian LI Jianfeng XIE Xiaofeng CUI Luhua XI Wenhui WAN Man PENG Bin LIU Yexin WANG Sheng GOU Zongyu YUE Tianyi YU Lichun LI Jia WANG Chuankai LIU Xin XIN Mengna JIA Zheng BO Jia LIU Runzhi WANG Shengli NIU Kuan ZHANG Yi YOU Bing LIU Jiangang LIU | 2020 | Science China(Information Sciences)2020，63，4： | 3 |
| 3 | Microfluidic-enabled ambient-temperature synthesis of ultrasmall bimetallic nanoparticles显示文摘The production of bimetallic nanoparticles with ultrasmall sizes is the constant pursuit in chemistry and materials science because of their promising applications in catalysis,electronics and sensing.Here we report ambient-temperature preparation of bimetallic NPs with tunable size and composition using microfluidic-controlled co-reduction of two metal precursors on silicon surface.Instead of free diffusion of metal ions in bulk system,microfluidic flow could well control the local ions concentration,thus leading to homogenous and controllable reduction rate among different nucleation sites.By controlling precursor concentration,flow rate and reaction time,we rationally design a series of bimetallic NPs including Ag-Cu,Ag-Pd,Cu-Pt,Cu-Pd and Pt-Pd NPs with ultrasmall sizes(~3.0 nm),tight size distributions(relative standard deviation(RSD)<21%),clean surface,and homogenous elemental compositions among particles(standard deviation(SD)of weight ratios<3.5%).This approach provides a facile,green and scalable method toward the synthesis of diverse bimetallic NPs with excellent activity. | Huayi Shi Bin Song Runzhi Chen Qiang Zhang Guyue Hu Jing Li Jinhua Wang Xinyu Meng Houyu Wang Yao He | 2022 | Nano Research2022，15，1： | 2 |
| 4 | Study on the Influencing Factors of Land Transfer Price in the Context of Rural Land Reform显示文摘Agricultural land is the key to large-scale agricultural management,and the transfer price is the key to the success or failure of land transfer. At present,there are many problems in the pricing of rural land transfer in China,such as low price,random pricing,and large price difference,which seriously hinder the development of rural land transfer. Drawing lessons from the research results of domestic and foreign scholars,combined with the actual situation of rural land transfer in China,this paper analyzes the influencing factors of land transfer price in the context of rural land reform. Finally,according to the influence of different factors on the behavior of agricultural land transfer,this paper proposes establishing and perfecting the evaluation system of contracted land,perfecting the evaluation institution of transferred land assets and establishing a unified dynamic monitoring system of land transfer price in the whole country,and then driving the broad masses of farmers to get rich together,which is of great significance to achieving the revitalization of China’s rural areas. | Runzhi WANG | 2019 | Asian Agricultural Research2019，11，8： | 2 |
| 5 | Positioning taxonomic research for the future显示文摘Why do taxonomists matter? The work of taxonomists is often understated if not completely misunderstood. Without taxonomists, organisms cannot be accurately identified, neither can these organisms be given universally accepted names, and reliably positioned in the phylogenetic tree of life. Thanks to the work of taxonomists over the last 269 years since Carl Linnaeus established the binomial system, we can now measure the health and wealth of our biodiversity in a refined, science-based inventory prescribed by stringent nomenclatural rules. | Deyuan Hong Wenying Zhuang Min Zhu Keping Ma Xiaoquan Wang Dawei Huang Yalin Zhang Guodong Ren Wenjun Bu Wanzhi Cai Dong Ren Ding Yang Aiping Liang Fengyan Bai Runzhi Zhang Fumin Lei Shuqiang Li Hongzhi Kong Lei Cai Yucheng Dai Chaodong Zhu Qisen Yang Jun Chen Zhongli Sha Jianping Jiang Jing Che Donghui Wu Jiatang Li Qiang Wang Xinli Wei Ming Bai Xingyue Liu Xuexin Chen Gexia Qiao | 2022 | Zoological Systematics2022，47，3： | 2 |

| 13 | Construction of 3,9-diazatetraasteranes and 3,9-diazatetracyclododecanes by photocycloaddition reaction of 1,4-dihydropyridines:Experimental and theoretical investigation显示文摘A photocycloaddition reaction of ethyl 1,4-diaryl-1,4-dihydropyridine-3-carboxylate for the construction of 3,9-diazatetraasteranes(Pr)and 3,9-diazatetracyclododecanes(P2)is reported for the first time.The types of reaction product clearly differ with solvent,regardless of the irradiation wavelength.The difference in Pi and P2 lies in the second step of the intramolecular[2+2]photocyclization.In order to further investigate this phenomenon and gain a deeper understanding of the photochemical behavior of 1,4-dihydropyridines,DFT and TDDFT theoretical calculations are performed.The results provide a good explanation for the formation of 3,9-diazatetraasteranes and 3,9-diazatetracyclododecanes. | Runzhi Sun Xiuqing Song Shijie Wang Xiaokun Zhang Hong Yan Yeming Wang | 2023 | Chinese Chemical Letters2023，34，12： | 0 |

| 15 | Bearing Capacity of Livestock and Poultry Breeding in Nanjing City Based on Planting-breeding Pattern显示文摘To assess the status of environmental bearing capacity of livestock and poultry manure in Nanjing City,the environmental pollution warning value and environmental bearing potential of livestock and poultry manure in various districts of Nanjing were calculated according to livestock and poultry manure discharge coefficient and manure content. The results showed that based on planting-breeding pattern,the livestock and poultry manure load in Nanjing City was14. 08 t/hm^2 pig manure equivalent; the warning values of environmental bearing capacity of livestock and poultry breeding calculated by nitrogen and phosphorus were 0. 23 and 0. 26,respectively,which were within the scope of environmental bearing capacity,with no threat to the environment. Under the premise of reasonable planing of livestock and poultry breeding and comprehensive utilization of manure,the environmental bearing potential of livestock and poultry breeding in Nanjing City were 5. 667 3 million( nitrogen) and 11. 109 1 million( phosphorus) pigs equivalent,and there were nearly one third of bearing space more than the existing total breeding quantity. | Du Juan Zhang Yongqing Zhang Zhenlan Wang Runzhi | 2017 | Animal Husbandry and Feed Science2017，9，1： | 0 |
| 16 | Efficacy and safety of external tissue expansion technique in the treatment of soft tissue defects:a systematic review and meta-analysis of outcomes and complication rates显示文摘Background:Currently,various external tissue expansion devices are becoming widely used.Considering the scarcity of relevant application standards,this systematic review was performed to explore the effectiveness and safety of external tissue expansion techniques for the reconstruction of soft tissue defects.Method:A systematic review and meta-analysis on the efficacy and safety of external tissue expansion technique was conducted.A comprehensive search was performed in the following electronic databases:PubMed/Medline,Embase,Cochrane Library(Wiley Online Library),andWeb of Science.Studies reporting patients with soft tissue defects under the treatment of external tissue expansion technique were included.Results:A total of 66 studies with 22 different types of external tissue expansion devices met the inclusion criteria.We performed a descriptive analysis of different kinds of devices.A single-arm meta-analysis was performed to evaluate the efficacy and safety of the external tissue expansion technique for different aetiologies.The pooled mean wound healing time among patients with defects after fasciotomy was 10.548 days[95%confidence interval(CI)=5.796-15.299].The pooled median wound healing times of patients with defects after excisional surgery,trauma,chronic ulcers and abdominal defects were 11.218 days(95%CI=6.183-16.253),11.561 days(95%CI=7.062-16.060),15.956 days(95%CI=11.916-19.996)and 12.853 days(95%CI=9.444-16.227),respectively.The pooled wound healing rates of patients with defects after fasciotomy,excisional surgery,trauma,chronic ulcers and abdominal defects were 93.8%(95%CI=87.1-98.2%),97.2%(95%CI=92.2-99.7%),97.0%(95%CI=91.2-99.8%),99.5%(95%CI=97.6-100%),and 96.8%(95%CI=79.2-100%),respectively.We performed a subgroup analysis in patients with diabetic ulcers and open abdominal wounds.The pooled median wound healing time of patients with diabetic ulcers was 11.730 days(95%CI=10.334-13.125).The pooled median wound healing time of patients with open abdomen defects was 48.810 days(95%CI=35.557-62.063)and the pooled successful healing rate was 68.8%(95%CI=45.9-88.1%).A total of 1686 patients were included,265(15.7%)of whom experienced complications.The most common complication was dehiscence(n=53,3.14%).Conclusions:Our systematic review is the first to demonstrate the efficacy and safety of external tissue expansion in the management of soft tissue defects.However,we must interpret the meta-analysis results with caution considering the limitations of this review.Large-scale randomized controlled trials and long-term follow-up studies are still needed to confirm the effectiveness and evaluate the quality of healing. | Xirui Tong Jianyu Lu Wei Zhang Siqiao Wang Runzhi Huang Xianliang Zhang Jie Huang Yushu Zhu Shichu Xiao Shizhao Ji Zhaofan Xia | 2022 | Burns & Trauma2022，10，1： | 0 |
| 17 | A novel molecular classification method for osteosarcoma based on tumor cell differentiation trajectories显示文摘Subclassification of tumors based on molecular features may facilitate therapeutic choice and increase the response rate of cancer patients.However,the highly complex cell origin involved in osteosarcoma(OS)limits the utility of traditional bulk RNA sequencing for OS subclassification.Single-cell RNA sequencing(sc RNA-seq)holds great promise for identifying cell heterogeneity.However,this technique has rarely been used in the study of tumor subclassification.By analyzing sc RNA-seq data for six conventional OS and nine cancellous bone(CB)samples,we identified 29 clusters in OS and CB samples and discovered three differentiation trajectories from the cancer stem cell(CSC)-like subset,which allowed us to classify OS samples into three groups.The classification model was further examined using the TARGET dataset.Each subgroup of OS had different prognoses and possible drug sensitivities,and OS cells in the three differentiation branches showed distinct interactions with other clusters in the OS microenvironment.In addition,we verified the classification model through IHC staining in 138 OS samples,revealing a worse prognosis for Group B patients.Furthermore,we describe the novel transcriptional program of CSCs and highlight the activation of EZH2 in CSCs of OS.These findings provide a novel subclassification method based on sc RNA-seq and shed new light on the molecular features of CSCs in OS and may serve as valuable references for precision treatment for and therapeutic development in OS. | Hao Zhang Ting Wang Haiyi Gong Runyi Jiang Wang Zhou Haitao Sun Runzhi Huang Yao Wang Zhipeng Wu Wei Xu Zhenxi Li Quan Huang Xiaopan Cai Zaijun Lin Jinbo Hu Qi Jia Chen Ye Haifeng Wei Jianru Xiao | 2023 | Bone Research2023，11，1： | 0 |
| 18 | EVs-mediated delivery of CB2 receptor agonist for Alzheimer’s disease therapy显示文摘Alzheimer’s disease(AD)is a typical neurodegenerative disease that leads to irreversible neuronal degeneration,and effective treatment remains elusive due to the unclear mechanism.We utilized biocompatible mesenchymal stem cell-derived extracellular vesicles as carriers loaded with the CB2 target medicine AM1241(EVs-AM1241)to protect against neurodegenerative progression and neuronal function in AD model mice.According to the results,EVs-AM1241 were successfully constructed and exhibited better bioavailability and therapeutic effects than bare AM1241.The Morris water maze(MWM)and fear conditioning tests revealed that the learning and memory of EVs-AM1241-treated model mice were significantly improved.In vivo electrophysiological recording of CA1 neurons indicated enhanced response to an auditory conditioned stimulus following fear learning.Immunostaining and Western blot analysis showed that amyloid plaque deposition and amyloidβ(Aβ)-induced neuronal apoptosis were significantly suppressed by EVs-AM1241.Moreover,EVs-AM1241 increased the number of neurons and restored the neuronal cytoskeleton,indicating that they enhanced neuronal regeneration.RNA sequencing revealed that EVs-AM1241 facilitated Aβphagocytosis,promoted neurogenesis and ultimately improved learning and memory through the calcium-Erk signaling pathway.Our study showed that EVs-AM1241 efficiently reversed neurodegenerative pathology and enhanced neurogenesis in modelmice,indicating that they are very promising particles for treating AD. | Yanjing Zhu Ruiqi Huang Deheng Wang Liqun Yu Yuchen Liu Runzhi Huang Shuai Yin Xiaolie He Bairu Chen Zhibo Liu Liming Cheng Rongrong Zhu | 2023 | Asian Journal of Pharmaceutical Sciences2023，18，4： | 0 |
| 19 | Latent extinction risk of soil fauna in Beijing:a 4-year study from 2013 to 2016显示文摘Soil ecosystems are far more functionally valuable than previously thought,but soil animals are less visible and often overlooked.Here,we surveyed population sizes of different animal orders in both urban and rural Beijing from 2013 to 2016,to study the impact of increasing urbanization on the ecology of soil fauna.We found 10 orders had less than 1%of soil-animal population in both urban and rural areas.Populations of 6 orders in urban areas were far smaller than those in rural areas.Between 2013 and 2016,both urban and rural areas had experienced a substantial long-term population decrease,and soil animals in Beijing suffered a 52.8%loss of population.Our study indicates 45.5%of orders may be in danger of local extinction,and 27.3%of orders seem highly susceptible to urbanization.Over just four years the soil-animal population in Beijing is shrinking fast thanks largely to increasing urbanization.This raises the worrying prospect of a future soil fauna that may be at risk of local extinction in cities.It is therefore necessary to provide a pragmatic approach to soil-animal diversity conservation.Moreover,the deeper understanding of soil extinction ecology opens up an exciting frontier of opportunities for future research. | Wei Wang Qilin Ren Runzhi Zhang Pengxiang Wu | 2021 | Ecosystem Health and Sustainability2021，7，1： | 0 |
