| 1 | Neuronal apoptosis in cerebral ischemia/reperfusion area following electrical stimulation of fastigial nucleus显示文摘Previous studies have indicated that electrical stimulation of the cerebellar fastigial nucleus in rats may reduce brain infarct size, increase the expression of Ku70 in cerebral ischemia/ reperfusion area, and decrease the number of apoptotic neurons. However, the anti-apoptotic mechanism of Ku70 remains unclear. In this study, fastigial nucleus stimulation was given to rats 24, 48, and 72 hours before cerebral ischemia/reperfusion injury. Results from the electrical stimulation group revealed that rats exhibited a reduction in brain infarct size, a significant increase in the expression of Ku70 in cerebral ischemia/reperfusion regions, and a decreased number of terminal deoxynucleotidyl transferase dUTP nick end labeling(TUNEL)-positive cells. Double immunofluorescence staining revealed no co-localization of Ku70 with TUNEL-positive cells. However, Ku70 partly co-localized with Bax protein in the cytoplasm of rats with cerebral ischemia/reperfusion injury. These findings suggest an involvement of Ku70 with Bax in the cytoplasm of rats exposed to electrical stimulation of the cerebellar fastigial nucleus, and may thus provide an understanding into the anti-apoptotic activity of Ku70 in cerebral ischemia/reperfusion injury. | Jingli Liu Jinpin Li Yi Yang Xiaoling Wang Zhaoxia Zhang Lei Zhang | 2014 | Neural Regeneration Research2014，9，7： | 26 |

| 4 | Influence of surfactants used in surfactant-polymer flooding on the stability of Gudong crude oil emulsion显示文摘The influences of an anionic-nonionic composite surfactant and petroleum sulfonate, used in surfactant-polymer flooding in Shengli Gudong oilfield, East China, on the interfacial properties of Gudong crude model oil and synthetic formation water was studied by measuring interfacial tension, interfacial viscoelasticity and Zeta potential. The in? uence of the surfactants on the stability of Gudong water-in-oil (W/O) and oil-in-water (O/W) emulsions was evaluated by separating water from the W/O emulsion and residual oil in the aqueous phase of the O/W emulsion respectively. The results showed that the two kinds of surfactants, namely anionic-nonionic composite surfactant and petroleum sulfonate, are both able to decrease the interfacial tension between the oil phase and the aqueous phase and increase the surface potential of the oil droplets dispersed in the O/W emulsion, which can enhance the stability of the W/O and O/W crude oil emulsions. Compared with petroleum sulfonate, the anionic-nonionic composite surfactant is more interfacially active and able to enhance the strength of the interfacial film between oil and water, hence enhance the stability of the W/O and O/W emulsions more effectively. | Dong Zhaoxia Lin Meiqin Wang Hao Li Mingyuan | 2010 | Petroleum Science2010，7，2： | 10 |

| 6 | Actual evapotranspiration of subalpine meadows in the Qilian Mountains, Northwest China显示文摘As a main component in water balance,evapotranspiration(ET)is of great importance for water saving,especially in arid and semi-arid areas.In this study,the FAO(Food and Agriculture Organization)Penman-Monteith model was used to estimate the magnitude and temporal dynamics of reference evapotranspiration(ET0)in 2014 in subalpine meadows of the Qilian Mountains,Northwest China.Meanwhile,actual ET(ETc)was also investigated by the eddy covariance(EC)system.Results indicated that ETc estimated by the EC System was 583 mm,lower than ET0(923 mm)estimated by the FAO Penman-Monteith model in 2014.Moreover,ET0 began to increase in March and reached the peak value in August and then declined in September,however,ETc began to increase from April and reached the peak value in July,and then declined in August.Total ETc and ET0 values during the growing season(from May to September)were 441 and 666 mm,respectively,which accounted for 75.73%of annual cumulative ETc and 72.34%of annual cumulative ET0,respectively.A crop coefficient(kc)was also estimated for calculating the ETc,and average value of kc during the growing season was 0.81(ranging from 0.45 to 1.16).Air temperature(Ta),wind speed(u),net radiation(Rn)and soil temperature(Ts)at the depth of 5 cm and aboveground biomass were critical factors for affecting kc,furthermore,a daily empirical kc equation including these main driving factors was developed.Our result demonstrated that the ETc value estimated by the data of kc and ET0 was validated and consistent with the growing season data in 2015 and 2016. | GAO Yunfei ZHAO Chuanyan Muhammad W ASHIQ WANG Qingtao RONG Zhanlei LIU Junjie MAO Yahua GUO Zhaoxia WANG Wenbin | 2019 | Journal of Arid Land2019，11，3： | 8 |
| 7 | Modeling CADASIL vascular pathologies with patient-derived induced pluripotent stem cells显示文摘Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy(CADASIL)is a rare hereditary cerebrovascular disease caused by a NOTCH3 mutation.However,the underlying cellular and molecular mechanisms remain unidentified.Here,we generated non-integrative induced pluripotent stem cells(iPSCs)from fibroblasts of a CADASIL patient harboring a heterozygous NOTCH3 mutation(c.3226C>T,p.R1076C).Vascular smooth muscle cells(VSMCs)differentiated from CADASIL-specific iPSCs showed gene expression changes associated with disease phenotypes,including activation of the NOTCH and NF-kB signaling pathway,cytoskeleton disorganization,and excessive cell proliferation.In comparison,these abnormalities were not observed in vascular endothelial cells(VECs)derived from the patients iPSCs.Importantly,the abnormal upregulation of NF-kB target genes in CADASIL VSMCs was diminished by a NOTCH pathway inhibitor,providing a potential therapeutic strategy for CADASIL.Overall,using this iPSCbased disease model,our study identified clues for studying the pathogenic mechanisms of CADASIL and developing treatment strategies for this disease. | Chen Ling Zunpeng Liu Moshi Song Weiqi Zhang Si Wang Xiaoqian Liu Shuai Ma Shuhui Sun Lina Fu Qun Chu Juan Carlos Izpisua Belmonte Zhaoxia Wang Jing Qu Yun Yuan Guang-Hui Liu | 2019 | Protein & Cell2019，10，4： | 7 |
| 8 | Decentralized Event-Triggered Average Consensus for Multi-Agent Systems in CPSs with Communication Constraints显示文摘The paper investigates decentralized event-triggered average consensus problem for multi-agent systems in cyberphysical systems(CPSs) with communication constraints.To reduce communication burden and improve the communication efficiency of multi-agent systems in CPSs,event-trigger is distributed at subsystem/agent level.A multi-agent system is then modeled as a reduced dimension hybrid system by taking into account decentralized event-triggered mechanism,communication delays and data dropouts within one framework.Some sufflcient conditions for average consensus of each agent and an upper bound of communication delay and maximal allowable number of successive data dropouts(MANSD) are obtained,which can conveniently provide the relationship between the triggering parameters,communication constraints and the system stability.Specially,the quantitative relationship between the triggering parameters,MANSD and the system stability is derived.Finally,simulation results are given to illustrate the effectiveness of the proposed method. | Zhaoxia Wang Minrui Fei Dajun Du Min Zheng | 2015 | IEEE/CAA Journal of Automatica Sinica2015，2，3： | 6 |

| 11 | Temperature influence on macro-mechanics parameter of intact coal sample containing original gas from Baijiao Coal Mine in China显示文摘Investigation of temperature effect on mechanical parameters of coal is very important for understanding the mechanical response of coal bed at high temperature.It is especially benefcial for mitigating the thermal-induced disasters occurred in those coal mines suffering from heat hazard.In this work,coal samples,obtained from the No.2442 working face of Baijiao Coal Mine,were subjected to uniaxial compression ranging from 20 to 40℃ with an interval of 5℃.The apparatus used was designed to obtain deformation of a stressed sample,as well as the emission of gases desorbing from coal matrix.The adsorbed gas desorption caused by heating is measured during the entire testing.It is evident that the concentrations of releasing gas(containing methane,carbon dioxide and ethane)slightly rise with increasing temperature.Gas movement observed is closely related to the deformation of coal sample.Both uniaxial compressive strength and elastic modulus of coal samples tend to reduce with temperature.It reveals that increasing temperature can not only result in thermal expansion of coal,but also lead to desorption of preexisting gas in coal which can in turns harden coal due to shrinks of the coal matrix.Even though desorption of adsorbed gas can contribute to the hardening effect for the heated coal,by comparison to the results,it could be inferred that the softening of coal resulted from thermal expansion still predominates changes in mechanical characters of coal sample with temperature at the range from20 to 40℃. | Wang Chunguang He Manchao Zhang Xiaohu Liu Zhaoxia Zhao Tongbin | 2013 | International Journal of Mining Science and Technology2013，23，4： | 4 |
| 12 | Effects of transport distance and flow discharge of overland flow on destruction of Ultisol aggregates显示文摘The destruction of soil aggregates upon transport by overland flow may produce a significant effect on sediment transport capacity and general intensity of erosion. The particle size distribution of destructed soil aggregates has a close relation to the surface runoff and permeability of soils. The objective of this study is to quantify the effects of transport distance and flow discharge of overland flow on the destruction of aggregates of Ultisols in a 3.8 m long flume with a fixed bed. A series of experiments were carried out at a slope of 17.6%, including six transport distances (9-108 m) and eight discharges (0.4-1.2 L/s). The results indicate that (1) the extent of the destruction of aggregates became weaker with the decrease in size over the same transport distances or at the same discharges; (2) the aggregates derived from Shale were rapidly abraded and had more serious destruction as compared to the aggregates from Quaternary red clay during the transport process, which was relevant to the stability difference of the two parent materials; (3) two stages of aggregate breakdown could be identified in terms of the coefficient during transport, that is, the aggregates were rapidly abraded and became round and were predominantly broken down into smaller fragments at the first stage, while the smaller fragments and the round aggregates were weakly abraded with reduction in weight and their shape became regular; and (4) the extent of the destruction decreased with increasing discharge, which was due to the changes in the hydraulic properties (flow depth and friction factor) and in movement modes during the transport process. The analysis of the characteristics on aggregate destruction by overland flow can contribute to the development of soil erosion models. | Junguang Wang Zhaoxia Li Chongfa Cai Wei Yang | 2012 | Particuology2012，10，5： | 4 |
| 13 | Numerical Simulations of an Advection Fog Event over Shanghai Pudong International Airport with the WRF Model显示文摘A series of numerical simulations is conducted to understand the formation, evolution, and dissipation of an advection fog event over Shanghai Pudong International Airport(ZSPD) with the Weather Research and Forecasting(WRF) model. Using the current operational settings at the Meteorological Center of East China Air Traffic Management Bureau, the WRF model successfully predicts the fog event at ZSPD. Additional numerical experiments are performed to examine the physical processes associated with the fog event. The results indicate that prediction of this particular fog event is sensitive to microphysical schemes for the time of fog dissipation but not for the time of fog onset. The simulated timing of the arrival and dissipation of the fog, as well as the cloud distribution, is substantially sensitive to the planetary boundary layer and radiation(both longwave and shortwave) processes. Moreover, varying forecast lead times also produces different simulation results for the fog event regarding its onset and duration, suggesting a trade-off between more accurate initial conditions and a proper forecast lead time that allows model physical processes to spin up adequately during the fog simulation. The overall outcomes from this study imply that the complexity of physical processes and their interactions within the WRF model during fog evolution and dissipation is a key area of future research. | Caiyan LIN Zhongfeng ZHANG Zhaoxia PU Fengyun WANG | 2017 | Journal of Meteorological Research2017，31，5： | 4 |
| 14 | Diagnosis and treatment of infantile malignant solid tumors in Beijing,China:A multicenter 10-year retrospective study显示文摘Importance:Cancer is the main cause of death by disease in children.Children experience the highest incidence of cancer in the first year of life.However,there is no comprehensive registration system for children with tumors in China.Objective:To summarize the diagnosis and treatment of infant cancer and analyze the status of standardized diagnosis and management among several treatment centers in Beijing,China,thereby providing evidence to guide further clinical research.Methods:From January 1,2010 to December 31,2019,patients with newly diagnosed infantile malignant solid tumors were admitted to six large tertiary pediatric solid tumor diagnosis and treatment centers in Beijing.The epidemiology,clinical features,and therapeutic effects of tumors in these patients were analyzed retrospectively.All patients were followed up until March 31,2020.Results:In total,938 patients were enrolled in this study.There were 530 boys(56.5%)and 408 girls(43.5%);the median age was 6.0 months(range,0-12.0 months).The three most common tumors were retinoblastoma in 366 patients(39.0%),neuroblastoma in 266 patients(28.4%),hepatoblastoma in 133 patients(14.2%),and central nervous system tumors in 52 patients(5.5%).The estimated 5-year overall survival rate was 81.3%±1.8%,and the 5-year event-free survival rate was 71.8%±2.9%.The 5-year overall survival rates of non-rhabdomyosarcoma soft tissue sarcoma,neuroblastoma,and retinoblastoma were 100%,88%±2.2%,and 86.9%±2.1%,respectively.The 5-year event-free survival rates were 81.1%±2.7%for neuroblastoma,81.6%±9.8%for non-rhabdomyosarcoma soft tissue sarcoma,and 72.7%±14.1%for extracranial malignant germ cell tumors.Interpretation:The three most common infantile malignant solid tumors were retinoblastoma,neuroblastoma,and hepatoblastoma.Multidisciplinary combined diagnosis and treatment is needed for infantile tumors. | Mei Jin Zhi Tian Yao Xie Zhaoxia Zhang Miao Li YaxiongYu Weiling Zhang Junyang Zhao Huanmin Wang Qi Zeng Long Li Ming Ge Ning Sun Xiaolun Zhang Jian Gong Wanshui Wu Rong Liu Weihong Zhao Dongsheng Huang Xiaoli Ma | 2020 | Pediatric Investigation2020，4，3： | 3 |

| 17 | Rough communication of crisp concept in fuzzy approximation spaces显示文摘To study the problem of knowledge translation in fuzzy approximation spaces, the concept of rough communication of crisp set in fuzzy approximation spaces is proposed. In a rough communication of crisp set in fuzzy approximation spaces, the problem of uncertainty exists, for each agent has a different language and cannot provide precise communication to each other. By means of some concepts, such as CF rough communication cut, which is a bridge between fuzzy concept and crisp concept, cut analysis of CF rough communication is made, and the relation theorem between CF rough communication and rough communication of crisp concept is obtained. Finally, in order to give an intuitive analysis of the relation between CF rough communication and rough communication of crisp concept, an example is given. | Wang Hongkai Guan Yanyong Yu Zhaoxia | 2009 | Journal of Systems Engineering and Electronics2009，20，2： | 3 |
| 18 | Leaf gas exchange and photosynthesis curves of Elymus nutans and Potentilla anserina under fencing and grazing conditions in the Qilian Mountains, Northwest China显示文摘Potentilla anserina L.and Elymus nutans Griseb.are dominant species in the subalpine meadows of China.Grazing is one of the most important factors that influence community structure and productivity of subalpine meadows.Understanding how grazing changes photosynthetic capability is essential for preservation and restoration of grasslands.However,information about the effects of grazing on photosynthetic capability remains inadequate.Experiments were conducted in fencing and grazing areas in the Qilian Mountains,Northwest China.The leaf gas exchange and photosynthetic curves of P.anserina and E.nutans were measured at different growth stages.Results showed that grazing decreased the values of leaf gas exchange parameters,such as net photosynthetic rate,stomatal conductance,transpiration rate,and intercellular CO2 concentration of P.anserina and E.nutans.In addition,grazing decreased the values of net photosynthetic rate-photosynthetically active radiation(PN-PAR)curve parameters,such as light-saturated net photosynthetic rate,apparent quantum efficiency,light compensation point,light saturation point,and dark respiration rate.Our results demonstrated that grazing was the primary limiting factor for photosynthesis of dominant grassland species in the study area. | LIU Junjie WANG Xiaoping GAO Yunfei RONG Zhanlei ZHANG Guangde WANG Wenbin GE Lijuan MAO Yahua GUO Zhaoxia ZHAO Chuanyan | 2019 | Journal of Arid Land2019，11，3： | 3 |
| 19 | Electrical conductivities of carbon nanotube-filled polycarbonate/polyester blends显示文摘Carbon nanotube (CNT)-filled polycarbonate (PC)/poly(butylene terephthalate) (PBT) and polycarbonate (PC)/poly(ethylene terephthalate) (PET) blends containing 1 wt% CNTs over a wide range of blend compositions were prepared by melt mixing in a torque rheometer to investigate the structure-electrical conductivity relationship. Field emission scanning electron microscopy was used to observe the blend morphology and the distribution of CNTs. The latter was compared with the thermodynamic predictions through the calculation of wetting coefficients. It was found that CNTs are selectively localized in the polyester phase and conductive blends can be obtained over the whole composition range (20 wt%, 50 wt% and 80 wt% PBT) for CNT-filled PC/PBT blends, while conductive CNT-filled PC/PET blends can only be obtained when PET is the continuous phase (50 wt%, 80 wt% PET). The dramatic difference in the electrical conductivity between the two types of CNT-filled PC/polyester blends at a low polyester content (20 wt%) was explained by the size difference of the dispersed phases on the basis of the transmission electron microscope micrographs. | XIONG ZhuoYue SUN Yao WANG Li GUO ZhaoXia YU Jian | 2012 | Science China Chemistry2012，55，5： | 3 |
| 20 | Influence factors of two dimensional position map on photomultiplier detector block designed by quadrant sharing technique显示文摘The position decoding accuracy and the spatial resolution of positron emission tomography detectors are greatly influenced by the performance of the two-dimensional position map,including the gain uniformity of photomultiplier tube (PMT),the baseline offset of the PMT signals and the accuracy of analogue to digital converter (ADC).In this work,a PMT-quadrant sharing detector was designed.Two data acquisition platforms are employed to conduct the influence factors on the two-dimensional position map performances,one was that the waveforms of the PMT signals were scanned by the sequence acquisition mode based on the oscilloscope of LeCroy waveRunner 204MXi-A,and another was a self-developed high speed ADC data acquisition module.Results show that the event decoding positions were concentrated on the PMT with higher gain,the position map was distorted at the baseline offset of signal,and the cross-line artifacts were caused by the insufficient ADC sampling bit for a larger size position map.All the parameters need be adjusted properly to stabilize a real system,and the flexible oscilloscope platform can be used to design the detector block and the other platform with high ADC accuracy.Likely,the electrical circuit with a proper ADC accuracy adjusts the PMT gains and baseline offsets. | WEI Qingyang WANG Shi Ma Tianyu MA Fei DAI Tiantian XU Tianpeng WU Zhaoxia JIN Yongjie LIU Yaqiang | 2011 | Nuclear Science and Techniques2011，22，4： | 3 |
