| 1 | The shortest period of coal spontaneous combustion on the basis of oxidative heat release intensity显示文摘It’s necessary to forecast the shortest spontaneous combustion period for preventing and controlling the coal spontaneous combustion.During the experimental process,a calculating model of the SSCP is established on the basis of the oxidative heat release intensity and thermal capacity at different temperatures.According to the basic parameters of spontaneous combustion,heat of water evaporation and gas desorption,the SSCPs of different coals are further predicted.Finally,this study analyzed the relationships of the SSCP and the judging indexes of the self-ignite tendency.The result shows that the SSCP non-linearly increases with the decrease of dynamic oxygen adsorption and increase of activation energy.Compared with the practical fire situation of mine,this reliable method can meet the actual requirement of mine production. | Yang Yongliang Li Zenghua Hou Shisong Gu Fanjun Gao Siyuan Tang Yibo | 2014 | International Journal of Mining Science and Technology2014，24，1： | 5 |
| 2 | Effect of Zhu-yuan decoction in patients with chronic rhinosinusitis after functional endoscopic sinus surgery显示文摘OBJECTIVE: To investigate the effectiveness and safety of Zhu-yuan decoction(ZYD) in patients after functional endoscopic sinus surgery(FESS).METHODS: A total of 85 patients were randomized into two groups: 44 were treated with intranasal corticosteroids(INC), and 41 were given Chinese herbal medicine(CHM). Patients with chronic rhinosinusitis(CRS) who underwent FESS were prospectively enrolled in the study. Before surgery, they were evaluated by visual analog scale(VAS), nasal endoscopy, computed tomography(CT), and routine blood test. After surgery, they were randomized to take ZYD or INC for 12 weeks and revaluated by VAS; nasal endoscopy at 4, 8, and 12 weeks;and CT at 12 weeks after surgery.RESULTS: In the both groups, VAS and endoscopyscores decreased significantly at 4, 8, and 12 weeks,and CT scores after treatment declined at 12 weeks compared with baseline scores. No significant differences were observed with regard to postoperative VAS, endoscopy, or CT scores between groups.ZYD, combined with surgery, can reduce VAS, nasal endoscopy, and CT scores and has the same efficacy and safety profile as INC in post-FESS management.No fatalities or major adverse events occurred in either group.CONCLUSION: Our findings suggest that ZYD has similar effects and safety profiles in patients after FESS compared with INC. | Li Jing Zheng Chunquan Lin Hai Yang Chen Gu Siyuan Wang Yi Duan Honggang | 2018 | Journal of Traditional Chinese Medicine2018，38，1： | 3 |
| 3 | Towards carbon neutrality:A study on China's long-term low-carbon transition pathways and strategies显示文摘As the world's biggest carbon dioxide(CO_(2))emitter and the largest developing country,China faces daunting challenges to peak its emissions before 2030 and achieve carbon neutrality within 40 years.This study fully considered the carbon-neutrality goal and the temperature rise constraints required by the Paris Agreement,by developing six long-term development scenarios,and conducting a quantitative evaluation on the carbon emissions pathways,energy transformation,technology,policy and investment demand for each scenario.This study combined both bottom-up and top-down methodologies,including simulations and analyses of energy consumption of end-use and power sectors(bottom-up),as well as scenario analysis,investment demand and technology evaluation at the macro level(top-down).This study demonstrates that achieving carbon neutrality before 2060 translates to significant efforts and overwhelming challenges for China.To comply with the target,a high rate of an average annual reduction of CO_(2) emissions by 9.3%from 2030 to 2050 is a necessity,which requires a huge investment demand.For example,in the 1.5℃ scenario,an investment in energy infrastructure alone equivalent to 2.6%of that year's GDP will be necessary.The technological pathway towards carbon neutrality will rely highly on both conventional emission reduction technologies and breakthrough technologies.China needs to balance a long-term development strategy of lower greenhouse gas emissions that meets both the Paris Agreement and the long-term goals for domestic economic and social development,with a phased implementation for both its five-year and long-term plans. | Jiankun He Zheng Li Xiliang Zhang Hailin Wang Wenjuan Dong Ershun Du Shiyan Chang Xunmin Ou Siyue Guo Zhiyu Tian Alun Gu Fei Teng Bin Hu Xiu Yang Siyuan Chen Mingtao Yao Zhiyi Yuan Li Zhou Xiaofan Zhao Ying Li Danwei Zhang | 2022 | Environmental Science and Ecotechnology2022，，1： | 2 |
| 4 | Adaptive two-filter smoothing based on second-order divided difference filter for distributed position and orientation system显示文摘The distributed position and orientation system(POS) uses transfer alignment to accurately measure multi-node time-spatial reference information, which is necessary for compensating the motion error of imaging sensors used in aerial surveys. Lever-arm deformation in transfer alignment will result in time-varying covariance of measurement noise, which decreases the estimation accuracy. To address this problem, a second-order adaptive divided difference two-filter smoother(ADDTFS) is proposed for transfer alignment. The second-order adaptive divided difference filter(ADDF2) severs as the forward filter to address nonlinearity in the system. The ADDF2 can estimate the measurement noise covariance in real time based on adaptive estimation using innovation information. The weighted statistical linear regression formulation is used in the backward filter to independently estimate the states and error covariance matrices.Then the forward and backward results are combined, to obtain high-precision estimation results in postprocessing. Finally, the vehicle experiment results show that the proposed method can improve the attitude precision of transfer alignment in a distributed POS by 27.84%, which has been successfully applied to motion compensation of airborne interferometric synthetic aperture radar(InS AR). | Jianli LI Siyuan ZOU Bin GU Jiancheng FANG | 2019 | Science China(Information Sciences)2019，62，9： | 1 |
| 5 | Localized-domains staging structure and evolution in lithiated graphite显示文摘Intercalation provides to the host materials a means for controlled variation of many physical/chemical properties and dominates the reactions in metal‐ion batteries.Of particular interest is the graphite intercalation compounds with intriguing staging structures,which however are still unclear,especially in their nanostructure and dynamic transition mechanism.Herein,the nature of the staging structure and evolution of the lithium(Li)‐intercalated graphite was revealed by cryogenic‐transmission electron microscopy and other methods at the nanoscale.The intercalated Li‐ions distribute unevenly,generating local stress and dislocations in the graphitic structure.Each staging compound is found macroscopically ordered but microscopically inhomogeneous,exhibiting a localized‐domains structural model.Our findings uncover the correlation between the long‐range ordered structure and short‐range domains,refresh the insights on the staging structure and transition of Li‐intercalated/deintercalated graphite,and provide effective ways to enhance the reaction kinetic in rechargeable batteries by defect engineering. | Suting Weng Siyuan Wu Zepeng Liu Gaojing Yang Xiaozhi Liu Xiao Zhang Chu Zhang Qiuyan Liu Yao Huang Yejing Li Mehmet NAteş Dong Su Lin Gu Hong Li Liquan Chen Ruijuan Xiao Zhaoxiang Wang Xuefeng Wang | 2023 | Carbon Energy2023，5，1： | 1 |
| 6 | Comprehensive report on China's Long-Term Low-Carbon Development Strategies and Pathways显示文摘1.Introduction 2020 is an unusual year in which the COVID-19 pandemic has raged through the globe,infecting tens of millions of people and killing hundreds of thousands.The pandemic has not only wreaked havoc on public health systems,economic activities,and people's lives,but also has greatly affected and will continue to reshape the world's political,economic,and trade patterns. | Jiankun He Zheng Li Xiliang Zhang Hailin Wang Wenjuan Dong Shiyan Chang Xunmin Ou Siyue Guo Zhiyu Tian Alun Gu Fei Teng Xiu Yang Siyuan Chen Mingtao Yao Zhiyi Yuan Li Zhou Xiaofan Zhao | 2020 | Chinese Journal of Population,Resources and Environment2020，18，4： | 1 |
| 7 | Efficient replacement of long DNA fragments via non-homologous end joining at norrcoding regions显示文摘Targeted double-strand breaks(DSBs)in genomes can be introduced efficiently by endonucleases(Umov et al.,2010;Jinek et al.,2012;Joung and Sander,2013),including zinc-finger nucleases,tran scription activator-like effector nu cleases,and clustered regularly in terspaced palindromic repeats(CRISPR)/Cas9.After DSBs,DNA repair is mainly via homology-directed repair(HDR)and/or non-homologous end joining(NHEJ)(Hustedt and Durocher,2016).It was reported that genomic DNA replacement can be achieved via HDR at the site of DSBs in multiple organisms(Dickinson et al.,2013;Yang et al.,2013;Zu et al.,2013),but the efficiency is still not enough for general application,in particular for replacing long DNA fragment that is more than hundreds of base pairs(bps).As NHEJ is 10-fold more active than HDR at DSB sites(Mao et al.,2008),we speculated that NHEJ can be utilized to implement long genomic DNA replacement with high efficiency. | Shanye Gu Jia Li Siyuan Li Jianbin Cao Jiwen Bu Yonggang Ren Wenjie Du Zhecong Chen Chufan Xu Mingcang Wang Lai Jiang Cheng Huang Jiulin Du | 2021 | Journal of Molecular Cell Biology2021，13，1： | 0 |
| 8 | Facile Synthesis of ZnO-Au Nanopetals and Their Application for Biomolecule Determinations显示文摘Using dextran as both reductant and stabilizing agent, nanopetals(ZnO-Au NPs) were easily synthesized and possessed a petal-like morphology. The feature structure and size of such ZnO-Au NPs were adjustable by regulating the amount of chloroauric acid(HAuCl4). Moreover, the electrochemical property of the obtained NPs was evaluated by being immobilized on the glassy carbon electrode(GCE), which performed both high sensitivity and stability in dopamine(DA) determinations. Furthermore, the as-prepared ZnO-Au NPs could also detect DA and uric acid(UA) simultaneously in the mixture without interference, indicating good selectivity and showing promising potential in biosensing. | XIANG Siyuan MENG Qingnan ZHANG Kai GU Yue LIU Wendong YANG Bai | 2019 | Chemical Research in Chinese Universities2019，35，5： | 0 |
| 9 | Magneto-mechanical effect of magnetic microhydrogel for improvement of magnetic neuro-stimulation显示文摘Superparamagnetic iron oxide(SPIO)nanoparticles play an important role in mediating precise and effective magnetic neurostimulation and can help overcome limitations related to penetration depth and spatial resolution.However,nanoparticles readily diffuse in vivo,decreasing the spatial resolution and activation efficiency.In this study,we employed a microfluidic means to fabricate injectable microhydrogels encapsulated with SPIO nanoparticles,which significantly improved the stability of nanoparticles,increased the magnetic properties,reinforced the stimulation effectivity.The fabricated magnetic microhydrogels were highly uniform in size and sphericity,enabling minimally invasive injection into brain tissue.The long-term residency in the cortex up to 22 weeks and the safety of brain tissue were shown using a mouse model.In addition,we quantitatively determined the magneto-mechanical force yielded by only one magnetic microhydrogel using a video-based method.The force was found to be within 7–8 pN under 10 Hz magnetic stimulation by both theoretical simulation and experimental measurement.Lastly,electrophysiological measurement of brain slices showed that the magnetic microhydrogels offer significant advantages in terms of neural activation relative to dissociative SPIO nanoparticles.A universal strategy is thus offered for performing magnetic neuro-stimulation with an improved prospect for biomedical translation. | Le Xue Qing Ye Linyuan Wu Dong Li Siyuan Bao Qingbo Lu Sha Liu Dongke Sun Zonghai Sheng Zhijun Zhang Ning Gu Jianfei Sun | 2023 | Nano Research2023，16，5： | 0 |
