| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |

| 4 | Synergistic effect between Sn and K promoters on supported platinum catalyst for isobutane dehydrogenation显示文摘Catalytic dehydrogenation of isobutane has recently received considerable attention because of the increasing demand for isobutene.In this study,the synergistic effect between Sn and K on PtSnK/γ-Al2O3 catalysts has been investigated by changing the content of Sn.It was found that with the presence of potassium,suitable addition of Sn could not only increase the metal dispersion,but also reduce the catalyst acidity.In these cases,the synergistic effect could also strengthen the interactions between the metal and support,which resulted in an increase in both catalytic activity and stability.In our experiments,Pt-0.6SnK/Al catalyst exhibited the lowest deactivation rate (12.4%) and showed a selectivity to isobutene higher than 94% at the isobutane conversion of about 45.3% after running the reaction for 6 h.However,with the excessive loading of Sn,surface property of active sites and the interactions between metal and support were changed.As a result,the initial optimal ratio between the metallic function and acid function would be destroyed,which was disadvantageous to the reaction. | Yiwei Zhang Yuming Zhou Lihui Wan Mengwei Xue Yongzheng Duan Xuan Liu | 2011 | Journal of Natural Gas Chemistry2011，20，6： | 12 |
| 5 | Effect of Strontium Addition to Platinum Catalyst for Propane Dehydrogenation显示文摘PtSnSr/HZSM-5 catalysts with different amounts of strontium were prepared by sequential impregnation method,and characterized by BET analysis,TEM,NH3-TPD,H2-TPR,TPO and TG techniques.The results showed that the addition of strontium could modify the characteristics and properties of both acid function and metal function of Pt-Sn-based catalysts.In this case,PtSnSr/HZSM-5 catalyst with an appropriate amount of Sr(1.2%) showed higher catalytic activity and lower amount of coke deposits than PtSn/HZSM-5 catalyst.However,excessive loading of Sr could facilitate the reduction of Sn,which was unfavorable to the reaction.Afterwards,1.0 m% of Na was added into the PtSnSr(1.2%)/HZSM-5 catalyst to improve the catalytic performance in propane dehydrogenation,and this catalyst displayed the best catalytic performance during our experiments.After having been subjected to reaction for 5h,the PtSnNa(1.0%)Sr(1.2%)/HZSM-5 catalyst had achieved a higher than 95% selectivity towards propene along with a corresponding propane conversion rate of 32.2%. | Huang Li Zhou Shijian Zhou Yuming Zhang Yiwei Zhang Shaobo Xu Jun | 2012 | China Petroleum Processing & Petrochemical Technology2012，14，3： | 11 |
| 6 | Deep Spectrum Prediction in High Frequency Communication Based on Temporal-Spectral Residual Network显示文摘High frequency(HF) communication is widely spread due to some merits like easy deployment and wide communication coverage. Spectrum prediction is a promising technique to facilitate the working frequency selection and enhance the function of automatic link establishment. Most of the existing spectrum prediction algorithms focus on predicting spectrum values in a slot-by-slot manner and therefore are lack of timeliness. Deep learning based spectrum prediction is developed in this paper by simultaneously predicting multi-slot ahead states of multiple spectrum points within a period of time. Specifically, we first employ supervised learning and construct samples depending on longterm and short-term HF spectrum data. Then, advanced residual units are introduced to build multiple residual network modules to respectively capture characteristics in these data with diverse time scales. Further, convolution neural network fuses the outputs of residual network modules above for temporal-spectral prediction, which is combined with residual network modules to construct the deep temporal-spectral residual network. Experiments have demonstrated that the approach proposed in this paper has a significant advantage over the benchmark schemes. | Ling Yu Jin Chen Yuming Zhang Huaji Zhou Jiachen Sun | 2018 | China Communications2018，15，9： | 9 |

| 8 | Evaluation of Typhoon Waves Simulated by Wave Watch-Ⅲ Model in Shallow Waters Around Zhoushan Islands显示文摘In this study, we simulated typhoon waves in the shallow waters around the Zhoushan Islands using the WaveWatch-Ⅲ(WW3) model version 5.16, the latest version released by the National Oceanic and Atmospheric Administration. Specifically, we used in-situ measurements to evaluate the performance of seven packages of input/dissipation source terms in the WW3 model. We forced the WW3 model by wind fields derived from a combination of the parametric Holland model and high-resolution European Center for Medium-Range Weather Forecasts(ECMWF) wind data in a 0.125? grid, herein called H-E winds. We trained the H-E winds by fitting a shape parameter B to buoy-measured observations, which resulted in a smallest root mean square error(RMSE) of 3 m s^(-1) for B, when treated as a constant 0.4. Then, we applied the seven input/dissipation terms of WW3, labelled ST1, ST2, ST2+STAB2, ST3, ST3+STAB3, ST4, and ST6, to simulate the significant wave height(SWH) up to 5 m during typhoons Fungwong and Chan-hom around the Zhoushan Islands. We then compared the SWHs of the simulated waves with those measured by the in-situ buoys. The results indicate that the simulation using ST2 performs best with an RMSE of 0.79 m for typhoon Fung-wong and an RMSE of 1.12 m for typhoon Chan-hom. Interestingly, we found the simulated SWH results to be relatively higher than those of the observations in the area between Hangzhou Bay and the Zhoushan Islands. This behavior is worthy of further investigation in the future. | SHENG Yexin SHAO Weizeng LI Shuiqing ZHANG Yuming YANG Hongwei ZUO Juncheng | 2019 | Journal of Ocean University of China2019，18，2： | 9 |
| 9 | The effect of Stokes drift on Ekman transport in the open sea显示文摘By introducing the wave-induced Coriolis-Stokes forcing into ageostrophic motion equation,the Eulerian transport is modified by the wave-induced Stokes drift.The long-term mean contributions of the Stokes transport with remotely generated swells being included to the ageostrophic transport are analyzed using the ECMWF(European Centre for Medium-Range Weather Forecasts) reanalysis data.The ratio of Stokes transport to Ekman transport in north-south(N-S) direction can reach a maximum of over 50% in the subtropical region.The preliminary influence of the Stokes transport on the North Pacific gyre is all year persistent,while the effect on the North Atlantic gyre is only obvious in boreal winter and early spring. | BI Fan WU Kejian ZHANG Yuming | 2012 | Acta Oceanologica Sinica2012，31，6： | 8 |
| 10 | Friction Characteristics of Impregnated and Non-Impregnated Graphite against Cemented Carbide under Water Lubrication显示文摘The friction behavior of resin-impregnated and non-impregnated graphite sliding against a cemented carbide in dry, oil, and water environments using a ring–ring configuration was investigated. Friction coefficients were recorded at various speeds. The results showed that the impregnated graphite exhibited much better friction properties under water or oil lubrication than non-impregnated graphite, and the impregnated graphite could remain in the stable friction regime under high pressure × velocity(pv).Based on scanning electron microscopy and Raman spectroscopy analyses, the different characteristics between impregnated and non-impregnated graphite were able to be attributed to the structure of the graphite and wettability of the lubricants. | Gaolong Zhang Ying Liu Fei Guo Xiangfeng Liu Yuming Wang | 2017 | Journal of Materials Science & Technology2017，33，10： | 8 |
| 11 | Comparative kinetics of coal and oil shale pyrolysis in a micro fluidized bed reaction analyzer显示文摘The characteristics and kinetics of coal and oil shale pyrolysis were comparatively studied by using a micro fluidized bed reaction analyzer(MFBRA).The isothermal differential model was first applied to calculate the kinetic parameters of activation energy and frequency factor according to the major gas components during pyrolysis.The results showed that the major gas components released from coal and oil shale under the isothermal condition had different initiating and ending time points,and the difference was more significant under the programmed heating conditions.The shrinking core model allowed better fitting relevance for the coal pyrolysis,while the three-dimension model was more suitable for oil shale pyrolysis,indicating that the gases from the pyrolysis process of coal and oil shale might go through different reaction paths.The activation energy of oil shale pyrolysis was 36.96 kJ·mol^(−1),larger than the value of pyrolysis of the two coals,which was 21.16 and 32.17 kJ·mol^(−1),respectively.The above results justified that the oil shale pyrolysis with high ash contents was somehow more difficult to take place in terms of higher activation energy and the MFBRA could be a useful tool to give some insight into the intrinsic kinetics and reaction mechanisms of coal and oil shale pyrolysis. | Yuming Zhang Mengxuan Zhao Rongxuan Linghu Chengxiu Wang Shu Zhang | 2019 | Carbon Resources Conversion2019，2，3： | 7 |
| 12 | Effect of Ga Addition on Catalytic Performance of PtSnNa/ZSM-5 Catalyst for Propane Dehydrogenation显示文摘PtSnNaGa/ZSM-5 catalysts with different contents of Ga were prepared and characterized by X-ray diffraction (XRD), nitrogen adsorption, hydrogen chemisorption, ammonia temperature-programmed desorption (NH3-TPD), hydrogen temperature-programmed reduction (H2-TPR), and temperature-programmed oxidation (TPO) techniques. The performances of these catalysts for propane dehydrogenation were investigated. The test results indicated that the addition of Ga not only could improve the catalytic stability and propene selectivity, but also could effectively prevent the catalysts from coking. It was found that the PtSnNaGa(0.5 m%)/ZSM-5 catalyst exhibited the best performance in terms of propene selectivity and propane conversion. The high catalytic performance was most probably attributed to the presence of Ga that could strength- en the interaction between metals and the support to stabilize the catalytic active sites. | Liu Xuan Zhou Yuming Zhang Yiwei Duan Yongzheng Xue Mengwei Wan Lihui (School of Chemistry and Chemical Engineering, Southeast University, Nanjing 211189) | 2011 | China Petroleum Processing & Petrochemical Technology2011，13，4： | 7 |
| 13 | The application and efficacy of stent place for Budd-Chiari syndrome显示文摘Objective To evaluate the application value and efficacy on stent place for Budd-Chiari syndrome(BCS). Methods From January 1990 to May 2017, 2228 patients with BCS were admitted to our institution. The mean age was 43.3 years. Stents were placed in inferior vena cava(IVC), hepatic vein(HV), or both after balloon dilation. During follow-up period, the patency of stent was evaluated by ultrasound regularly and the clinic sign was surveyed by letter, telephone or clinic visit. The restenosis of stent were treated with balloon dilatation and thrombolysis to restore the its function. Results IVC type was diagnosed in 1492 cases, HV type in 510 cases, and mixed type in 226 cases. Eighteen patients aborted treatment because of economic reasons, advanced liver cancer, severe scoliosis, or both bilateral iliac veins and total IVC occlusion. Among the other 2210 cases who underwent endovascular therapy, stents were implanted into IVC in 339 cases, HV in 97 cases, mixed type in 64 cases. The rate of restenosis in IVC stent was 11.50%(39/339). After repeat angioplasty, the long-term patency rate reached to 98.12%. The incidence of HV occlusion caused by IVC stent was 12.09%(n = 41). Restenosis occurred in 47 cases(48.45%) after HV stent placement. However, the 5-year patency rate was 91.75%(89/97) after repeat dilatation and stent re-implantation. The incidence of IVC obstruction caused by HV was 3.33%(3 cases). Conclusion IVC stent placement appears to be an effective treatment for the cases of IVC segmental occlusion, and at the same time, the stent has the dual role of compression and fixation of thrombus and support of lumen. The HV and accessory hepatic vein obstruction could happen when the IVC stent crossed these veins ostium. The incidence of the stent restenosis in the HV was higher than that in the IVC. | Maoheng Zu Hao Xu Yuming Gu Qingqiao Zhang Ning Wei Wei Xu Yanfeng Cui | 2018 | Journal of Interventional Medicine2018，1，3： | 7 |
| 14 | Effect of cerium addition on catalytic performance of PtSnNa/ZSM-5 catalyst for propane dehydrogenation显示文摘The effect of cerium addition on the catalytic performance of propane dehydrogenation over PtSnNa/ZSM-5 catalyst has been investigated by reaction tests and some physicochemical characterization such as XRD,BET,TEM,XPS,NH 3-TPD,H 2 chemisorption,TPR and TPO techniques.It has been found that with suitable amount of cerium addition,the platinum dispersion increased,while the carbon deposition tended to be eliminated easily.In these cases,the presence of cerium could not only realize the better distribution of metallic particles on the support,but also strengthen the interactions between Sn species and the support.Additionally,XPS spectra confirmed that more amounts of tin could exist in oxidized form,which was advantageous to the reaction.In our experiments,PtSnNaCe(1.1 wt%)/ZSM-5 catalyst exhibited the best catalytic performance.After running the reaction for 750 h,propane conversion was maintained higher than 30% with the corresponding selectivity to propylene of about 97%. | Mengwei Xue Yuming Zhou Yiwei Zhang Xuan Liu Yongzheng Duan Xiaoli Sheng | 2012 | Journal of Natural Gas Chemistry2012，21，3： | 6 |
| 15 | Effect of aluminum modification on catalytic properties of PtSn-based catalysts supported on SBA-15 for propane dehydrogenation显示文摘The catalytic properties of PtSn-based catalysts supported on siliceous SBA-15 and Al-modified SBA-15, such as Al-incorporated SBA-15 (AlSBA-15) and alumina-modified SBA-15 (Al2O3/SBA-15), for propane dehydrogenation were investigated. Al2O3/SBA-15 was prepared either by an impregnation method using aluminum nitrate aqueous solution, or by the treatment of SBA-15 with a Al(OC3H7)3 solution in anhydrous toluene. N2-physisorption, FT-IR spectroscopy, solid-state 27Al MAS NMR spectroscopy, hydrogen chemisorption, XRF, NH3 temperature-programmed desorption, X-ray photoelectron spectroscopy and TPO were used to characterize these samples. Among these catalysts, the PtSn-based catalyst supported on Al2O3/SBA-15, which was grafted with Al(OC3H7)3, exhibited the best catalytic performance in terms of activity and stability The possible reason was due to the high Pt metal dispersion and/or the strong interactions among Pt, Sn, and the support. | Yongzheng Duan Yuming Zhou Yiwei Zhang Xiaoli Sheng Shijian Zhou Zewu Zhang | 2012 | Journal of Natural Gas Chemistry2012，21，2： | 6 |
| 16 | Investigation on the fabrication of lightweight aggregate with acid-leaching tailings of vanadium-bearing stone coal minerals and red mud显示文摘Proper treatment of acidleaching tailings(ALTs)of vanadiumbearing stone coal minerals is of great urgency.One approach is adding it into the raw materials during the preparation of lightweight aggregate(LWA).But clay is always needed.In this paper,another solid waste,red mud,was mixed with ALTs as a source of flux components instead of clay.Evaluation of the physical characteristics,morphological structures,as well as crystal phases during the sintering process were investigated.When their mixtures with a proper ratio were sintered at 1080℃,a glassy phase with certain viscosity was formed,and the gases generated simultaneously were encapsulated by the melt.Finally,LWA with a onehour water absorption as low as 1.46%,a bulk density as low as 728.76 kgm 3 and a compressive strength as high as 10.77 MPa was fabricated. | Chunguang Song Hongling Zhang Yuming Dong Lili Pei Honghui Liu Junsheng Jiang Hongbin Xu | 2021 | Chinese Journal of Chemical Engineering2021，34，4： | 6 |

| 18 | Characteristics of vascular lesions in patients with posterior circulation infarction according to age and region of infarct显示文摘Patients with posterior circulation infarction underwent CT angiography and magnetic resonance angiography. Intracranial and extracranial vasculopathy was evaluated according to age group and location of stroke. Patients aged > 60 years and < 60 years had similar rates of vertebral artery dominance and vertebrobasilar artery developmental or origin anomalies. Vertebrobasilar artery stenosis or occlusion and tortuosity occurred more frequently in patients aged > 60 years than < 60 years. The rates of vertebrobasilar artery anomalies and tortuosity were high in patients with posterior circulation infarction. Vertebrobasilar artery tortuosity occurred more frequently in patients aged > 60 years, whereas vertebrobasilar artery developmental anomalies occurred with similar frequency in patients aged < 60 years and > 60 years. Patients with infarction of the brainstem or cerebellum were more likely to have vertebral artery stenosis or occlusion, basilar artery stenosis or occlusion, vertebral artery dominance or tortuosity, and basilar artery tortuosity, and patients with infarction of the thalamus, medial temporal, or occipital lobes were more likely to have stenosis or occlusion of the vertebral or basilar arteries. Vertebrobasilar artery tortuosity, vertebral artery dominance (hypoplasia), and congenital variations of the vertebrobasilar system may lead to posterior circulation infarction at different locations in different age groups. | Daopei Zhang Shuling Zhang Hongtao Zhang Yuming Xu | 2012 | Neural Regeneration Research2012，7，32： | 5 |
| 19 | Strongly Coupled 2D Transition Metal Chalcogenide-MXene-Carbonaceous Nanoribbon Heterostructures with Ultrafast Ion Transport for Boosting Sodium/Potassium Ions Storage显示文摘Combining with the advantages of two-dimensional(2D)nanomaterials,MXenes have shown great potential in next generation rechargeable batteries.Similar with other 2D materials,MXenes generally suffer severe self-agglomeration,low capacity,and unsatisfied durability,particularly for larger sodium/potassium ions,compromising their practical values.In this work,a novel ternary heterostructure self-assembled from transition metal selenides(MSe,M=Cu,Ni,and Co),MXene nanosheets and N-rich carbonaceous nanoribbons(CNRibs)with ultrafast ion transport properties is designed for sluggish sodium-ion(SIB)and potassium-ion(PIB)batteries.Benefiting from the diverse chemical characteristics,the positively charged MSe anchored onto the electronegative hydroxy(-OH)functionalized MXene surfaces through electrostatic adsorption,while the fungal-derived CNRibs bonded with the other side of MXene through amino bridging and hydrogen bonds.This unique MXene-based heterostructure prevents the restacking of 2D materials,increases the intrinsic conductivity,and most importantly,provides ultrafast interfacial ion transport pathways and extra surficial and interfacial storage sites,and thus,boosts the high-rate storage performances in SIB and PIB applications.Both the quantitatively kinetic analysis and the density functional theory(DFT)calculations revealed that the interfacial ion transport is several orders higher than that of the pristine MXenes,which delivered much enhanced Na+(536.3 mAh g^(−1)@0.1 A g^(−1))and K^(+)(305.6 mAh g^(−1)@1.0 A g^(−1))storage capabilities and excel-lent long-term cycling stability.Therefore,this work provides new insights into 2D materials engineering and low-cost,but kinetically sluggish post-Li batteries. | Junming Cao Junzhi Li Dongdong Li Zeyu Yuan Yuming Zhang Valerii Shulga Ziqi Sun Wei Han | 2021 | Nano-Micro Letters2021，13，7： | 5 |
| 20 | Wear behavior of WC-Ni sliding against graphite under water lubrication显示文摘Wear of hard materials in contact with softer materials is a neglected area of research. However, we observed considerable wear phenomenon at a hard WC-Ni surface sliding over soft graphite under water lubrication. The influences of applied load and the application history on the wear of surface were addressed in our experimental design. Wear of both graphite and WC-Ni surfaces increased with a greater applied load and repeated sliding. The topographies of the worn surfaces showed clear micro-scratches on the hard WC-Ni surface. Scanning electron microscopy and X-ray photoelectron spectroscopy analyses revealed that the abrasive wear of the WC-Ni surface could be attributed to hard WC particles embedded in the graphite surface. These hard particles were formed by shearing of sharp WC-Ni asperities under certain conditions and intrinsic defects of the WC-Ni surface could accelerate this wear process. | Gaolong Zhang Ying Liu Yuechang Wang Fei Guo Xiangfeng Liu Yuming Wang | 2017 | Journal of Materials Science & Technology2017，33，11： | 5 |
