| 1 | Studying the mechanical properties of the soil-root interface using the pullout test method显示文摘It is important to quantify the effect of the root diameter, the embedment length of the root and load speed on the soil-root interface mechanical properties for studying the root anchorage. The soilroot interface mechanical properties can be obtained through the pullout force and root slippage curve(F-S curve). About 120 Pinus tabulaeformis single roots whose diameters ranged from 1 mm to 10 mm divided into 6 groups based on different root embedment length(50 mm, 100 mm and 150 mm) and different load velocity(10 mm·min^(-1), 50 mm·min^(-1), 100 mm·min^(-1) and 300 mm·min^(-1)) were investigated using the pullout method. This study aims to explore the mechanical properties of the soil-root interface in the real conditions using the pullout test method. The results showed two kinds of pullout test failure modes during the experimental process: breakage failure and pullout failure. The results showed that the roots were easier to be broken when the root diameter was smaller or the loading speed was larger. The relationship between the maximum anchorage force and root diameter was linear and the linearly dependent coefficient(R^2) was larger than 0.85. The anchorage force increased with the root embedment length. An increase of 10%^(-1)5% for the maximumanchorage force was found when load speed increased from 10 to 300 mm.min^(-1). The mean peak slippage of the root was from 13.81 to 35.79 mm when the load velocity varied from 10 to 300 mm.min^(-1). The study will be helpful for the design of slopes reinforced by vegetation and in predicting risk of uprooting of trees, and will have practical benefits for understanding the mechanism of landslide. | JI Xiao-dong CONG Xu DAI Xian-qing ZHANG Ao CHEN Li-hua | 2018 | Journal of Mountain Science2018，15，4： | 13 |
| 2 | New prospecting progress using information and big data of coal and oil exploration holes on sandstone-type uranium deposit in North China显示文摘1.Objective A series of Mesozoic-Cenozoic continental sedimentary basins exist in North China,coexisting with coal,oil/gas,and salt resources.Many previous drilling projects have been conducted within these basins to explore coal,petroleum,and mineral resources,however,these data have not been integrated due to different industries owners.In order to efficiently explore the large-sized,easily extracted,and environmentally friendly,sandstone-type uranium deposits,previous coal and oil exploration drilling-hole data are systematically collected, processed,and analyzed to improve the sandstone-type uranium prospecting exploitation.At the same time,we also discussed the uranium source,ore-forming process and model for the sandstone-type uranium deposits. | Ruo-shi Jin Pei-sen Miao Xian-zhang Sima Reng-An Yu Yin-hang Cheng Chao Tang Tian-fu Zhang Cong Ao Xue-ming Teng | 2018 | China Geology2018，1，1： | 12 |

| 4 | Sterilization and disinfection methods for decellularized matrix materials:Review,consideration and proposal显示文摘Sterilization is the process of killing all microorganisms,while disinfection is the process of killing or removing all kinds of pathogenic microorganisms except bacterial spores.Biomaterials involved in cell experiments,animal experiments,and clinical applications need to be in the aseptic state,but their physical and chemical properties as well as biological activities can be affected by sterilization or disinfection.Decellularized matrix(dECM)is the low immunogenicity material obtained by removing cells from tissues,which retains many inherent components in tissues such as proteins and proteoglycans.But there are few studies concerning the effects of sterilization or disinfection on dECM,and the systematic introduction of sterilization or disinfection for dECM is even less.Therefore,this review systematically introduces and analyzes the mechanism,advantages,disadvantages,and applications of various sterilization and disinfection methods,discusses the factors influencing the selection of sterilization and disinfection methods,summarizes the sterilization and disinfection methods for various common dECM,and finally proposes a graphical route for selecting an appropriate sterilization or disinfection method for dECM and a technical route for validating the selected method,so as to provide the reference and basis for choosing more appropriate sterilization or disinfection methods of various dECM. | Meihan Tao Tianrang Ao Xiaoyan Mao Xinzhu Yan Rabia Javed Weijian Hou Yang Wang Cong Sun Shuang Lin Tianhao Yu Qiang Ao | 2021 | Bioactive Materials2021，6，9： | 2 |

| 7 | Multivariate MOF for optimizing atmospheric water harvesting显示文摘Atmospheric water harvesting offers a powerful and promising solution to address the problem of global freshwater scarcity.In the past decade,significant progress has been achieved in utilizing hydrolytically stable metal-organic frameworks as recyclable water-sorbent materials under low relative humidity,especially in those arid areas.Recently,Yaghi's group has employed a combined crystallographic and theoretical technique to decipher the water filling mechanism in MOF-303,where the polar organic linkers rather than the inorganic units of MOF are demonstrated as the key factor.Hence,the hydrophilic strength of the water-binding pocket in MOFs can be optimized through the approach of multivariate modulations,resulting in enhanced water harvesting properties. | Ao Ma Hengjiang Cong Hexiang Deng | 2022 | Green Energy & Environment2022，7，4： | 0 |
| 8 | Shell characterization and effects on cavity volume of wild Jinjiang oyster Crassostrea ariakensis in different estuaries of China显示文摘Jinjiang oyster Crassostrea ariakensis,a species with economic and ecological value,is distributed along the estuaries and coasts of East Asia.With the decline in natural resources,the conservation and aquaculture of this species is urgent.However,studies characterizing their shell shape remain scarce.We investigated the morphological differences in the shells of wild Jinjiang oysters from six populations(Qinzhou,Shanghai,Nantong,Qingdao,and Binzhou hard or muddy bottom)along the coast of China.The color of the shell and adductor muscle scar showed associations with temperature gradient along its geographical distribution.Oyster shape was defined by shell height to shell length ratio,and the ratio varies among geographic locations of the populations.They were found nearly round(Qinzhou and Nantong populations),oval(Qingdao and Binzhou populations),or water-droplet-shaped(Shanghai population).Binzhou populations living on muddy substrates are more elongated than those on hard substrate.In addition,we developed a method to measure the cavity volume in oysters.Correlation and path analysis showed that shell height significantly influenced cavity volume.The synergistic effect of the two factors(the height,length,and width of the shell in pairs)on the cavity volume resulted in differences between northern and southern groups:samples from the southern group(Qinzhou and Shanghai)showed correlation between shell height and shell width,while those from the northern group(Nantong,Qingdao,and Binzhou)showed correlation between shell height and shell length.All populations showed significant correlation between shell height and cavity height,and shell length and cavity length,while the correlation between shell width and cavity width was minimal,which may have been resulted from uneven shell thickness.The linear equation for shell height and cavity volume under different ratios of shell height to length was obtained.In this study,we determined that shell height has the most influence on cavity volume,and specific cavity volume fitting linear equations are given for different shell types,which may provide a reference for future oyster breeding for shell shaping. | Qi YANG Ao LI Luping WANG Rihao CONG Jianming YANG Guofan ZHANG Wei WANG Li LI | 2023 | Journal of Oceanology and Limnology2023，41，5： | 0 |
| 9 | Re-examination of the impact of some non-pharmaceutical interventions and media coverage on the COVID-19 outbreak in Wuhan显示文摘In this paper,based on the classic Kermack-McKendrick SIR model,we propose an ordinary differential equation model to re-examine the COVID-19 epidemics in Wuhan where this disease initially broke out.The focus is on the impact of all those major nonpharmaceutical interventions(NPIs)implemented by the local public healthy authorities and government during the epidemics.We use the data publicly available and the nonlinear least-squares solver lsqnonlin built in MATLAB to estimate the model parameters.Then we explore the impact of those NPIs,particularly the timings of these interventions,on the epidemics.The results can help people review the responses to the outbreak of the COVID-19 inWuhan,while the proposed model also offers a framework for studying epidemics of COVID-19 and/or other similar diseases in other places,and accordingly helping people better prepare for possible future outbreaks of similar diseases. | Ao Li Yang Wang Pingping Cong Xingfu Zou | 2021 | Infectious Disease Modelling2021，6，1： | 0 |
| 10 | Genotyping Characteristics of Human Fecal Escherichia coli and Their Association with Multidrug Resistance in Miyun District, Beijing显示文摘Objective To explore the genotyping characteristics of human fecal Escherichia coli(E. coli) and the relationships between antibiotic resistance genes(ARGs) and multidrug resistance(MDR) of E. coli in Miyun District, Beijing, an area with high incidence of infectious diarrheal cases but no related data.Methods Over a period of 3 years, 94 E. coli strains were isolated from fecal samples collected from Miyun District Hospital, a surveillance hospital of the National Pathogen Identification Network. The antibiotic susceptibility of the isolates was determined by the broth microdilution method. ARGs,multilocus sequence typing(MLST), and polymorphism trees were analyzed using whole-genome sequencing data(WGS).Results This study revealed that 68.09% of the isolates had MDR, prevalent and distributed in different clades, with a relatively high rate and low pathogenicity. There was no difference in MDR between the diarrheal(49/70) and healthy groups(15/24).Conclusion We developed a random forest(RF) prediction model of TEM.1 + baeR + mphA + mphB +QnrS1 + AAC.3-IId to identify MDR status, highlighting its potential for early resistance identification. The causes of MDR are likely mobile units transmitting the ARGs. In the future, we will continue to strengthen the monitoring of ARGs and MDR, and increase the number of strains to further verify the accuracy of the MDR markers. | ZHANG Wei Wei ZHU Xiao Lin DENG Le Le HAN Ya Jun LI Zhuo Wei WANG Jin Long CHEN Yong Liang WANG Ao Lin TIAN Er Li CHENG Bin XU Lin Hua CHEN Yi Cong TIAN Li Li HE Guang Xue | 2023 | Biomedical and Environmental Sciences2023，36，5： | 0 |
