| 1 | Impact angle control over composite guidance law based on feedback linearization and finite time control显示文摘The impact angle control over guidance(IACG) law against stationary targets is proposed by using feedback linearization control(FLC) and finite time control(FTC). First, this paper transforms the kinematics equation of guidance systems into the feedbackable linearization model, in which the guidance law is obtained without considering the impact angle via FLC. For the purpose of the line of sight(LOS) angle and its rate converging to the desired values, the second-order LOS angle is considered as a double-integral system. Then, this paper utilizes FTC to design a controller which can guarantee the states of the double-integral system converging to the desired values. Numerical simulation illustrates the performance of the IACG, in contrast to the existing guidance law. | ZHANG Xiaojian LIU Mingyong LI Yang ZHANG Feihu | 2018 | Journal of Systems Engineering and Electronics2018，29，5： | 5 |
| 2 | New bolting structure of fractured roof based on the Bossinesq equations显示文摘Present support theories contain a number of shortcomings in the designation of fractured roof bolt parameters of rectangular or trapezoidal coal roadways.Roof fall accidents occur easily in this kind of roadway.Based on the Bossinesq equations and the Mohr strength theory,we propose a theory of an anchored cluster structure for fractured roofs and have investigated the formation of such an anchored cluster structure,its self stability mechanism and mechanical properties.The results show that an anchor and the surrounding fractured rock can form a string-like supporting structure,referred to as the structure of an anchored cluster for rational bolt parameters.Not only can the structure maintain its own stability,but as well undertake the load of the overlying strata.The designated support parameters,based on anchored cluster theory can overcome the shortcomings of other support theories applied to a fractured roof of rectangular roadways or could not be calculated.Our anchored cluster theory can provide a theoretical basis for the design of support for rectangular fractured roofs.Furthermore,the theory will help to reduce the probability of roof fall accidents caused by local fractured rock blocks,which can destroy a supporting structure. | LIU, Hongtao MA, Nianjie ZHAO, Feihu LIU, Fengming | 2010 | Mining Science and Technology2010，20，2： | 4 |

| 4 | Determination of paraquat in water samples using a sensitive fluorescent probe titration method显示文摘Paraquat(PQ),a nonselective herbicide,is non-fluorescent in aqueous solutions.Thus,its determination through direct fluorescent methods is not feasible.The supramolecular inclusion interaction of PQ with cucurbit[7]uril was studied by a fluorescent probe titration method.Significant quenching of the fluorescence intensity of the cucurbit[7]uril-coptisine fluorescent probe was observed with the addition of PQ.A new fluorescent probe titration method with high selectivity and sensitivity at the ng/mL level was developed to determine PQ in aqueous solutions with good precision and accuracy based on the significant quenching of the supramolecular complex fluorescence intensity.The proposed method was successfully used in the determination of PQ in lake water,tap water,well water,and ditch water in an agricultural area,with recoveries of 96.73% to 105.77%.The fluorescence quenching values(F) showed a good linear relationship with PQ concentrations from 1.0 × 108 to 1.2× 105 mol/L with a detection limit of 3.35 × 109 mol/L.In addition,the interaction models of the supramolecular complexes formed between the host and the guest were established using theoretical calculations.The interaction mechanism between the cucurbit[7]uril and PQ was confirmed by 1 H NMR spectroscopy. | Feihu Yao Hailong Liu Guangquan Wang Liming Du Xiaofen Yin Yunlong Fu | 2013 | Journal of Environmental Sciences2013，25，6： | 2 |

| 9 | Genome-wide profiling of circular RNAs,alternative splicing,and R-loops in stem-differentiating xylem of Populus trichocarpa显示文摘Circular RNAs(circRNAs)are a recently dis-covered type of non‐coding RNA derived from pre‐mRNAs.R‐loops consist of a DNA:RNA hybrid andthe associated single‐stranded DNA.InArabi-dopsis thaliana,circRNA:DNA R‐loops regulatealternative splicing(AS)ofSEPALLATA3(SEP3).However,the occurrence and functions ofcircRNAs and R‐loops inPopulus trichocarpaarelargely unexplored.Here,we performed circRNA‐enriched sequencing in the stem‐differentiatingxylem(SDX)ofP.trichocarpaand identified 2,742distinct circRNAs,including circ‐CESA4,circ‐IRX7,and circ‐GUX1,which are generated from genesinvolved in cellulose,and hemicellulose biosyn-thesis,respectively.To investigate the roles ofcircRNAs in modulating alternative splicing(AS),we detected 7,836 AS events using PacBio Iso‐Seq and identified 634 circRNAs that overlappedwith 699 AS events.Furthermore,using DNA:RNAhybrid immunoprecipitation followed by se-quencing(DRIP‐seq),we identified 8,932 R‐looppeaks that overlapped with 181 circRNAs and 672AS events.Notably,several SDX‐related circRNAsoverlapped with R‐loop peaks,pointing to theirpossible roles in modulating AS in SDX.Indeed,overexpressing circ‐IRX7increased the levels ofR‐loop structures and decreased the frequency ofintron retention in linearIRX7transcripts.Thisstudy provides a valuable R‐loop atlas resourceand uncovers the interplay between circRNAs andAS in SDX ofP.trichocarpa. | Xuqing Liu Yubang Gao Jiakai Liao Miao Miao Kai Chen Feihu Xi Wentao Wei Huihui Wang Yongsheng Wang XiXu Anireddy S.N.Reddy Lianfeng Gu | 2021 | Journal of Integrative Plant Biology2021，63，7： | 1 |

| 19 | An inactivated recombinant rabies virus chimerically expressed RBD induces humoral and cellular immunity against SARS-CoV-2 and RABV显示文摘Many studies suggest that severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)can infect various animals and transmit among animals,and even to humans,posing a threat to humans and animals.There is an urgent need to develop inexpensive and efficient animal vaccines to prevent and control coronavirus disease 2019(COVID-19)in animals.Rabies virus(RABV)is another important zoonotic pathogen that infects almost all warmblooded animals and poses a great public health threat.The present study constructed two recombinant chimeric viruses expressing the S1 and RBD proteins of the SARS-CoV-2 Wuhan01 strain based on a reverse genetic system of the RABV SRV9 strain and evaluated their immunogenicity in mice,cats and dogs.The results showed that both inactivated recombinant viruses induced durable neutralizing antibodies against SARS-CoV-2 and RABV and a strong cellular immune response in mice.Notably,inactivated SRV-nCoV-RBD induced earlier antibody production than SRV-nCoV-S1,which was maintained at high levels for longer periods.Inactivated SRV-nCoV-RBD induced neutralizing antibodies against both SARS-CoV-2 and RABV in cats and dogs,with a relatively broadspectrum cross-neutralization capability against the SARS-CoV-2 pseudoviruses including Alpha,Beta,Gamma,Delta,and Omicron,showing potential to be used as a safe bivalent vaccine candidate against COVID-19 and rabies in animals. | Haili Zhang Hongli Jin Feihu Yan Yumeng Song Jiaxin Dai Cuicui Jiao Yujie Bai Jingxuan Sun Di Liu Shen Wang Mengyao Zhang Jilong Lu Jingbo Huang Pei Huang Yuanyuan Li Xianzhu Xia Hualei Wang | 2023 | Virologica Sinica2023，38，2： | 0 |
| 20 | Influence of positive end-expiratory pressure upregulation on the right ventricle in critical patients with acute respiratory distress syndrome:an observational cohort study显示文摘Background This study aimed to investigate the influence of positive end-expiratory pressure(PEEP)on the right ventricle(RV)of mechanical ventilation-assisted patients through echocardiography.Methods Seventy-six patients assisted with mechanical ventilation were enrolled in this study.Positive end-expiratory pressure was upregulated by 4 cm H_(2)O to treat acute respiratory distress syndrome,wherein echocardiography was performed before and after this process.Hemodynamic data were also recorded.All variables were compared before and after PEEP upregulation.The effect of PEEP was also evaluated in patients with and without decreased static lung compliance(SLC).Results Positive end-expiratory pressure upregulation significantly affected the RV function.Remarkable differences were observed in the following:Tei index(P=0.027),pulmonary artery pressure(P=0.039),tricuspid annular plane systolic excursion(P=0.014),early wave/atrial wave(P=0.002),diaphragm excursion(P<0.001),inferior vena cava collapsing index(P<0.001),and SLC(P<0.001).There were no significant changes in heart rate,respiratory rate,central venous pressure,mean arterial pressure,and base excess(P>0.05).Furthermore,the cardiac output of the RV was not significantly affected.In patients with decreased SLC(n=41),there were more significant changes in diaphragm excursion(P<0.001),inferior vena cava collapse index(P=0.025),pulmonary artery pressure(P<0.001),and tricuspid annular plane systolic excursion(P=0.007)than in those without decreased SLC(n=35).Conclusion Positive end-expiratory pressure upregulation significantly affected the RV function of critically ill patients with acute respiratory distress syndrome,especially in those with decreased SLC. | Hui Liu Mengjie Song Li Wang Jianguo Xiao Feihu Zhou | 2023 | Emergency and Critical Care Medicine2023，3，3： | 0 |
