| 1 | Mechanical model of water inrush from coal seam floor based on triaxial seepage experiments显示文摘In order to study the mechanism of confined water inrush from coal seam floor,the main influences on permeability in the process of triaxial seepage experiments were analyzed with methods such as laboratory experiments,theoretical analysis and mechanical model calculation.The crack extension rule and the ultimate destruction form of the rock specimens were obtained.The mechanism of water inrush was explained reasonably from mechanical point of view.The practical criterion of water inrush was put forward.The results show that the rock permeability 'mutation' phenomenon reflects the differences of stress state and cracks extension rate when the rock internal crack begins to extend in large-scale.The rock ultimate destruction form is related to the rock lithology and the angle between crack and principal stress.The necessary condition of floor water inrush is that the mining pressure leads to the extension and transfixion of the crack.The sufficient condition of floor water inrush is that the confined water’s expansionary stress in normal direction and shear stress in tangential direction must be larger than the internal stress in the crack.With the two conditions satisfied at the same time,the floor water inrush accident will occur. | Yihui Pang Guofa Wang Ziwei Ding | 2014 | International Journal of Coal Science & Technology2014，1，4： | 35 |

| 3 | Neutrophil extracellular traps mediate the crosstalk between glioma progression and the tumor microenvironment via the HMGB1/RAGE/IL-8 axis显示文摘Objective:Neutrophil extracellular traps(NETs)produced by tumor-infiltrating neutrophils(TINs)are associated with poor prognosis in patients with several types of cancer.However,the mechanisms underlying the involvement of NETs in glioma progression remain largely unknown.This study aimed to elucidate the roles of NETs in biological processes that drive the crosstalk between glioma progression and the tumor microenvironment.Methods:Neutrophil infiltration and NETs formation were investigated in glioma tissue through immunohistochemistry,and their relationships with clinicopathological features and outcomes were statistically evaluated.The effects of NETs on glioma cell progression were studied in a co-culture system.In vivo and in vitro experiments validated the reactive oxygen species activity and cytokine production of TINs,as well as the ERK signaling pathway activation and the metastasis of gliomas.Results:Neutrophil infiltration and NETs formation were induced in high-grade glioma compared with low-grade glioma.NETs induced by TINs were determined to be an oncogenic marker of high-grade gliomas and to be involved in cell proliferation and invasion.NETs overproduction promoted glioma cell proliferation,migration,and invasion.Furthermore,HMGB1 was found to bind to RAGE and activate the NF-κB signaling pathway in vitro.In addition,NETs stimulated the NF-κB signaling pathway,thus promoting IL-8 secretion in glioblastoma.Subsequently,IL-8 recruited neutrophils which in turn mediated NETs formation via the PI3 K/AKT/ROS axis in TINs.Conclusions:Our results suggest that NETs produced by TINs mediate the crosstalk between glioma progression and the tumor microenvironment by regulating the HMGB1/RAGE/IL-8 axis.Targeting NETs formation or IL-8 secretion may be an effective approach to inhibit glioma progression. | Caijun Zha Xiangqi Meng Lulu Li Shan Mi Da Qian Ziwei Li Pengfei Wu Shaoshan Hu Shihong Zhao Jinquan Cai Yanhong Liu | 2020 | Cancer Biology & Medicine2020，17，1： | 19 |
| 4 | A data-driven health indicator extraction method for aircraft air conditioning system health monitoring显示文摘Prognostics and Health Management(PHM) has become a very important tool in modern commercial aircraft. Considering limited built-in sensing devices on the legacy aircraft model,one of the challenges for airborne system health monitoring is to find an appropriate health indicator that is highly related to the actual degradation state of the system. This paper proposed a novel health indicator extraction method based on the available sensor parameters for the health monitoring of Air Conditioning System(ACS) of a legacy commercial aircraft model. Firstly, a specific Airplane Condition Monitoring System(ACMS) report for ACS health monitoring is defined. Then a non-parametric modeling technique is adopted to calculate the health indicator based on the raw ACMS report data. The proposed method is validated on a single-aisle commercial aircraft widely used for short and medium-haul routes, using more than 6000 ACMS reports collected from a fleet of aircraft during one year. The case study result shows that the proposed health indicator can effectively characterize the degradation state of the ACS, which can provide valuable information for proactive maintenance plan in advance. | Jianzhong SUN Chaoyi LI Cui LIU Ziwei GONG Ronghui WANG | 2019 | Chinese Journal of Aeronautics2019，32，2： | 14 |
| 5 | Antimony smelting process generating solid wastes and dust:Characterization and leaching behaviors显示文摘A large amount of solid waste has been produced by the antimony smelting process in the'World Capital of Antimony', Xikuangshan area in China. This study comprehensively investigated the physical and chemical characteristics of the various solid wastes, as well as the leaching behavior of the solid wastes, which included water-quenched slag,arsenic-alkali residue, desulfurized slag and blast furnace dust. These four types of waste were enriched in a variety of heavy metals and metalloids and more specifically with As and Sb levels up to 8.6 × 104 and 3.16 × 105mg/kg, respectively, in arsenic-alkali residue. For desulfurized slag and water-quenched slag, the leaching concentration of Sb significantly exceeded the acceptable limits during the leaching tests using the toxicity characteristic leaching procedure and the synthetic precipitation leaching procedure. In addition, As leaching in arsenic-alkali residue was extraordinarily hazardous, being three orders of magnitude higher than the regulatory level of As. According to the results of the extraction tests, all the tested wastes were classified as hazardous waste. | Xuejun Guo Kunpeng Wang Mengchang He Ziwei Liu Hailin Yang Sisi Li | 2014 | Journal of Environmental Sciences2014，26，7： | 13 |

| 8 | Laser joining of CFRTP to titanium alloy via laser surface texturing显示文摘Grid pattern was textured on Ti-6 Al-4 V alloy(TC4)substrate surface by nanosecond laser system.Laser joining of carbon fiber reinforced thermoplastic composite(CFRTP)to TC4 joints were performed,and the effect of texture grid depth was investigated.The contact angle of molten CFRTP on textured TC4 surface was measured and the tensile-shear force was tested.The fracture surface and interface morphology were observed.The results indicated that the wettability of molten CFRTP on TC4 surface improved remarkably after laser textured TC4.Shear force of CFRTP/TC4 joints was increased by 156%after laser textured TC4 surface.When the depth of grid was deeper than 100μm,contact angle increased and incomplete filling of molten CFRTP in grid occurred,the shear force thus decreased gradually.Resin-carbon fibers mixture was adhered on the fracture surface of TC4,and the variation tendency of adhesion ratio was consistent with that of shear force.TC4 matrix was exfoliated from substrate and adhered at the fracture surface of CFRTP,indicating stronger mechanical interlocking occurred at the joining interface after laser textured TC4 surface.Beside mechanical interlocking,compound layer consisted of CTi_(0.42)V_(1.58)carburization phase was also confirmed at interface,suggesting that chemical bonding also occurred at the joining interface. | Caiwang TAN Jianhui SU Ziwei FENG Yifan LIU Bo CHEN Xiaoguo SONG | 2021 | Chinese Journal of Aeronautics2021，34，5： | 11 |
| 9 | Internet of Things to network smart devices for ecosystem monitoring显示文摘Smart, real-time, low-cost, and distributed ecosystem monitoring is essential for understanding and managing rapidly changing ecosystems. However, new techniques in the big data era have rarely been introduced into operational ecosystem monitoring, particularly for fragile ecosystems in remote areas.We introduce the Internet of Things(IoT) techniques to establish a prototype ecosystem monitoring system by developing innovative smart devices and using IoT technologies for ecosystem monitoring in isolated environments. The developed smart devices include four categories: large-scale and nonintrusive instruments to measure evapotranspiration and soil moisture, in situ observing systems for CO2 and d13 C associated with soil respiration, portable and distributed devices for monitoring vegetation variables, and Bi-CMOS cameras and pressure trigger sensors for terrestrial vertebrate monitoring. These new devices outperform conventional devices and are connected to each other via wireless communication networks. The breakthroughs in the ecosystem monitoring IoT include new data loggers and longdistance wireless sensor network technology that supports the rapid transmission of data from devices to wireless networks. The applicability of this ecosystem monitoring IoT is verified in three fragile ecosystems, including a karst rocky desertification area, the National Park for Amur Tigers, and the oasis-desert ecotone in China. By integrating these devices and technologies with an ecosystem monitoring information system, a seamless data acquisition, transmission, processing, and application IoT is created. The establishment of this ecosystem monitoring IoT will serve as a new paradigm for ecosystem monitoring and therefore provide a platform for ecosystem management and decision making in the era of big data. | Xin Li Ning Zhao Rui Jin Shaomin Liu Xiaomin Sun Xuefa Wen Dongxiu Wu Yan Zhou Jianwen Guo Shiping Chen Ziwei Xu Mingguo Ma Tianming Wang Yonghua Qu Xinwei Wang Fangming Wu Yuke Zhou | 2019 | Science Bulletin2019，64，17： | 10 |
| 10 | A dual-pass data assimilation scheme for estimating surface fluxes with FY3A-VIRR land surface temperature显示文摘In this work, a dual-pass data assimilation scheme is developed to improve predictions of surface flux. Pass 1 of the dual-pass data assimilation scheme optimizes the model vegetation parameters at the weekly temporal scale, and Pass 2 optimizes the soil moisture at the daily temporal scale. Based on ensemble Kalman filter(EnKF), the land surface temperature(LST) data derived from the new generation of Chinese meteorology satellite(FY3A-VIRR) are assimilated into common land model(CoLM) for the first time. Six sites, Daman, Guantao, Arou, BJ, Miyun and Jiyuan, are selected for the data assimilation experiments and include different climatological conditions. The results are compared with those from a dataset generated by a multi-scale surface flux observation system that includes an automatic weather station(AWS), eddy covariance(EC) and large aperture scintillometer(LAS). The results indicate that the dual-pass data assimilation scheme is able to reduce model uncertainties and improve predictions of surface flux with the assimilation of FY3A-VIRR LST data. | XU TongRen LIU ShaoMin XU ZiWei LIANG ShunLin XU Lu | 2015 | Science China Earth Sciences2015，58，2： | 9 |
| 11 | Large-Scale Membrane Bioreactors for Industrial Wastewater Treatment in China:Technical and Economic Features,Driving Forces,and Perspectives显示文摘Membrane bioreactors(MBRs)have been and will continue playing an important role in industrial wastewater treatment and reuse in China.The sustainable development of MBR technology in its mature-application stage requires reciprocal interactions between engineering and research participants.Thus,in this study,a total of 182 large-scale MBR projects treating industrial wastewater(with individual treatment capacities5000 m3d1)commissioned and under construction from 2003 to 2019 were analyzed comprehensively.Fast growth of the cumulative treatment capacity was observed,with extension to diverse industries,and the super large-scale was enhanced recently.The treatment processes,pollutant removal efficiencies,and actual operational parameters were summarized regarding the particularity of industrial wastewater compared to municipal wastewater.Economic features including the total investment costs of the projects,their total footprint,and their operational energy consumption were analyzed as well.A vigorous MBR market has formed in China with the fast development of membrane elements and engineering suppliers,continuously increasing official oriented projects,and responsive and innovative business modes.MBR technology has been mostly applied in specific economic zones and water-deficient areas,but its widespread use all over China is foreseeable considering the vast future market for industrial wastewater treatment and recycling.The policy–economy and market–technology driving forces revealed that MBR is consistent with the national development demand.According to the survey and analysis,prospective development in both engineering and research aspects of MBR is proposed to maintain its competitive edge. | Jiao Zhang Kang Xiao Ziwei Liu Tingwei Gao Shuai Liang Xia Huang | 2021 | Engineering2021，7，6： | 9 |

| 13 | A lariat-derived circular RNA is required for plant development in Arabidopsis显示文摘Lariat RNA is produced during pre-mRNA splicing, and it is traditionally thought as by-products, due to the quick turnover by debranching followed by degradation. However, recent findings identified many lariat RNAs accumulate with a circular form in higher eukaryotes. Although the remarkable accumulation, biological consequence of lariat-derived circular RNAs(here we name laciRNAs) remains largely unknown. Here, we report that a specific laciRNA from At5 g37720 plays an essential role in plant development by regulating gene expression globally. We focus on 17 laciRNAs with accumulation in wild type plants by circular RNA sequencing in Arabidopsis. To determine biological functions of these laciRNAs, we constructed one pair of transgenic plants for each laciRNA, in which the local gene with or without introns was over-expressed in wild type plants,respectively. By comparing morphological phenotypes and transcriptomic profiles between two classes of transgenic plants, we show that over-expression of the laciRNA derived from the 1 st intron of At5 g37720 causes pleiotropic phenotypes, including curly and clustered leaf, late flowering, reduced fertility, and accompanied with altered expression of approximately 800 genes.Our results provide another example that a specific plant circular RNA regulates gene expression in a similar manner to that of other non-coding RNAs under physiological conditions. | Jinping Cheng Yong Zhang Ziwei Li Taiyun Wang Xiaotuo Zhang Binglian Zheng | 2018 | Science China(Life Sciences)2018，61，2： | 8 |
| 14 | Distribution and characteristic of PAHs in snow of Fildes Peninsula显示文摘Polycyclic aromatic hydrocarbons (PAHs) investigation in different matrices has been reported largely,whereas reports on snow samples were limited.Snow,as the main matrix in the polar region,has an important study meaning.PAHs in snow samples were analyzed to investigate the distribution and contamination status of them in the Antarctic,as well as to provide some references for global migration of PAHs.Snow samples collected in Fildes Peninsula were enriched and separated by solid-phase membrane disks and eluted by methylene dichloride,then quantified by gas chromatography/mass spectrometry.All types of PAHs were detected except for Benzo(a)pyrene.Principal component analysis method was applied to characterize them.Three factors (Naphthalene,Fluorene and Phenanthrene) accounted for 60.57%,21.61% and 9.80%,respectively.The results showed that the major PAHs sources maybe the atmospheric transportation,and the combustion of fuel in Fildes Peninsula.The comparison of concentration and types of PAHs between accumulated snow and fresh snow showed that the main compound concentrations in accumulated snow samples were higher than those in fresh ones.The risk assessment indicated that the amount of PAHs in the snow samples would not lead to ecological risk. | Guangshui Na Chunyang Liu Zhen Wang Linke Ge Xindong Ma Ziwei Yao | 2011 | Journal of Environmental Sciences2011，23，9： | 8 |
| 15 | Wearable skin-like optoelectronic systems with suppression of motion artifacts for cuff-less continuous blood pressure monitor显示文摘According to the statistics of the World Health Organization,an estimated 17.9 million people die from cardiovascular diseases each year,representing 31%of all global deaths.Continuous non-invasive arterial pressure(CNAP)is essential for the management of cardiovascular diseases.However,it is difficult to achieve long-term CNAP monitoring with the daily use of current devices due to irritation of the skin as well as the lack of motion artifacts suppression.Here,we report a high-performance skin-like optoelectronic system integrated with ultra-thin flexible circuits to monitor CNAP.We introduce a theoretical model via the virtual work principle for predicting the precise blood pressure and suppressing motion artifacts,and propose optical difference in the frequency domain for stable optical measurements in terms of skin-like devices.We compare the results with the blood pressure acquired by invasive(intra-arterial)blood pressure monitoring for>1500 min in total on 44 subjects in an intensive care unit.The maximum absolute errors of diastolic and systolic blood pressure were±7/±10 mm Hg,respectively,in immobilized,and±10/±14 mm Hg,respectively,in walking scenarios.These strategies provide advanced blood pressure monitoring techniques,which would directly address an unmet clinical need or daily use for a highly vulnerable population. | Haicheng Li Yinji Ma Ziwei Liang Zhouheng Wang Yu Cao Yuan Xu Hua Zhou Bingwei Lu Ying Chen Zhiyuan Han Shisheng Cai Xue Feng | 2020 | National Science Review2020，7，5： | 7 |

| 19 | Large-scale blow spinning of heat-resistant nanofibrous air filters显示文摘Particulate matter(PM)pollution has become a serious problem worldwide and various kinds of nanofibrous filters aiming to solve the problem have been developed.It is urgent to remove PM from high-temperature pollution sources,such as industrial emissions,coal furnaces,and automobile exhaust gases.However,filtration at pollution sources remains challenging because most existing air filters are not resistant to high temperature.Herein,heat-resistant polyimide(PI)nanofibrous air filters are fabricated via a simple and scalable solution blow-spinning method.These air filters show excellent thermal stability at high temperature up to 420℃.They exhibit a filtration efficiency as high as 99.73%at ambient temperature and over 97%at 300℃.In addition,a field test shows that the filters remove>97%of PM from the car exhaust fumes.Hence,the blow-spun PI nanofibrous membranes combined with the facile preparation strategy have great potential in high temperature air filtration fields and other similar applications such as water purification and protein separation. | Ziwei Li Jianan Song Yuanzheng Long Chao Jia Zhenglian Liu Lei Li Cheng Yang Junchen Liu Sen Lin Haiyang Wang Yibo Liu Minghao Fang Hui Wu | 2020 | Nano Research2020，13，3： | 6 |
| 20 | Enhancement of precursor amino acid supplies for improving bacitracin production by activation of branched chain amino acid transporter BrnQ and deletion of its regulator gene lrp in Bacillus licheniformis显示文摘Bacitracin,a new type of cyclic peptide antibiotic,is widely used as the feed additive in feed industry.Branched chain amino acids(BCAAs)are the key precursors for bacitracin synthesis.In this research,soybean meal was served as the raw material to supply precursor amino acids for bacitracin synthesis,and enhanced production of bacitracin was attempted by engineering BCAA transporter BrnQ and its regulator Lrp in the bacitracin industrial production strain Bacillus licheniformis DW2.Firstly,our results confirmed that Lrp negatively affected bacitracin synthesis in DW2,and deletion of lrp improved intracellular BCAA accumulations,as well as the expression level of BCAA transporter BrnQ,which further led to a 14.71%increase of bacitracin yield,compared with that of DW2.On the contrary,overexpression of Lrp decreased bacitracin yield by 12.28%.Secondly,it was suggested that BrnQ acted as a BCAA importer in DW2,and overexpression of BrnQ enhanced the intracellular BCAA accumulations and 10.43%of bacitracin yield.While,the bacitracin yield decreased by 18.27%in the brnQ deletion strain DW2△brnQ.Finally,BrnQ was further overexpressed in lrp deletion strain DW2△lrp,and bacitracin yield produced by the final strain DW2△lrp::BrnQ was 965.34 U/mL,increased by 22.42%compared with that of DW2(788.48 U/mL).Collectively,this research confirmed that Lrp affected bacitracin synthesis via regulating the expression of BCAA transporter BrnQ and BCAA distributions,and provided a promising strain for industrial production of bacitracin. | Jiang Zhu Dongbo Cai Haixia Xu Ziwei Liu Bowen Zhang Fei Wu Junhui Li Shouwen Chen | 2018 | Synthetic and Systems Biotechnology2018，3，4： | 6 |
