| 1 | UNSTEADY FLOW ANALYSIS AND EXPERIMENTAL INVESTIGATION OF AXIAL-FLOW PUMP显示文摘The three-dimensional unsteady turbulent flow in axial-flow pumps was simulated based on Navier-Stoke solver embedded with k-ε RNG turbulence model and SIMPLEC algorithm.Numerical results show that the unsteady prediction results are more accurate than the steady results,and the maximal error of unsteady prediction is only 4.54%.The time-domain spectrums show that the static pressure fluctuation curves at the inlet and outlet of the rotor and the outlet of the stator are periodic,and all have four peaks and four valleys.The pressure fluctuation amplitude increases from the hub to the tip at the inlet and outlet of the rotor,but decreases at the outlet of the stator.The pressure fluctuation amplitude is the greatest at the inlet of the rotor,and the average amplitude decreases sharply from the inlet to the outlet.The frequency spectrums obtained by Fast Fourier Transform(FFT) show that the dominant frequency is approximately equal to the blade passing frequency.The static pressure on the pressure side of hydrofoil on different stream surfaces remains almost consistent,and increases gradually from the blade inlet to the exit on the suction side at different time steps.The axial velocity distribution is periodic and is affected by the stator blade number at the rotor exit.The experimental results show that the flow is almost axial and the pre-rotation is very small at the rotor inlet under the conditions of 0.8 QN -1.2 QN.Due to the clearance leakage,the pressure,circulation and meridional velocity at the rotor outlet all decrease near the hub leakage and tip clearance regions. | ZHANG De-sheng SHI Wei-dong CHEN Bin GUAN Xing-fan | 2010 | Journal of Hydrodynamics2010,22,1: | 111 |

| 3 | Safety and efficacy of ciprofol vs.propofol for sedation in intensive care unit patients with mechanical ventilation:a multi-center,open label,randomized,phase 2 trial显示文摘Background:Ciprofol(HSK3486;Haisco Pharmaceutical Group Co.,Ltd.,Chengdu,China),developed as a novel 2,6-disubstituted phenol derivative showed similar tolerability and efficacy characteristics as propofol when applicated as continuous intravenous infusion for 12 h maintenance sedation in a previous phase 1 trial.The phase 2 trial was designed to investigate the safety,efficacy,and pharmacokinetic characteristics of ciprofol for sedation of patients undergoing mechanical ventilation.Methods:In this multicenter,open label,randomized,propofol positive-controlled,phase 2 trial,39 Chinese intensive care unit patients receiving mechanical ventilation were enrolled and randomly assigned to a ciprofol or propofol group in a 2:1 ratio.The ciprofol infusion was started with a loading infusion of 0.1-0.2 mg/kg for 0.5-5.0 min,followed by an initial maintenance infusion rate of 0.30 mg·kg^(-1)·h^(-1),which could be adjusted to an infusion rate of 0.06 to 0.80 mg·kg^(-1)·h^(-1),whereas for propofol the loading infusion dose was 0.5-1.0 mg/kg for 0.5-5.0 min,followed by an initial maintenance infusion rate of 1.50 mg·kg^(-1)·h^(-1),which could be adjusted to 0.30-4.00 mg·kg^(-1)·h^(-1)to achieve-2 to+1 Richmond Agitation-Sedation Scale sedation within 6-24 h of drug administration.Results:Of the 39 enrolled patients,36 completed the trial.The median(min,max)of the average time to sedation compliance values for ciprofol and propofol were 60.0(52.6,60.0)min and 60.0(55.2,60.0)min,with median difference of 0.00(95%confidence interval:0.00,0.00).In total,29(74.4%)patients comprising 18(69.2%)in the ciprofol and 11(84.6%)in the propofol group experienced 86 treatment emergent adverse events(TEAEs),the majority being of severity grade 1 or 2.Drug-and sedation-related TEAEs were hypotension(7.7%vs.23.1%,P=0.310)and sinus bradycardia(3.8%vs.7.7%,P=1.000)in the ciprofol and propofol groups,respectively.The plasma concentration-time curves for ciprofol and propofol were similar.Conclusions:ciprofol is comparable to propofol with good tolerance and efficacy for sedation of Chinese intensive care unit patients undergoing mechanical ventilation in the present study setting.Trial registration:ClinicalTrials.gov,NCT04147416. | Yongjun Liu Xiangyou Yu Duming Zhu Jun Zeng Qinhan Lin Bin Zang Chuanxi Chen Ning Liu Xiao Liu Wei Gao Xiangdong Guan | 2022 | Chinese Medical Journal2022,,9: | 19 |
| 4 | From concept to reality-A review to the primary test stand and its preliminary application in high energy density physics显示文摘Pulsed power technology,whereas the electrical energy stored in a relative long period is released in much shorter timescale,is an efficient method to create high energy density physics(HEDP)conditions in laboratory.Around the beginning of this century,China Academy of Engineering Physics(CAEP)began to build some experimental facilities for HEDP investigations,among which the Primary Test Stand(PTS),a multi-module pulsed power facility with a nominal current of 10 MA and a current rising time~90 ns,is an important achievement on the roadmap of the electro-magnetically driven inertial confinement fusion(ICF)researches.PTS is the first pulsed power facility beyond 10 TW in China.Therefore,all the technologies have to be demonstrated,and all the engineering issues have to be overcome.In this article,the research outline,key technologies and the preliminary HEDP experiments are reviewed.Prospects on HEDP research on PTS and pulsed power development for the next step are also discussed. | Jianjun Deng Weiping Xie Shuping Feng Meng Wang Hongtao Li Shengyi Song Minghe Xia Ji Ce An He Qing Tian Yuanchao Gu Yongchao Guan Bin Wei Xianbin Huang Xiaodong Ren Jiakun Dan Jing Li Shaotong Zhou Hongchun Cai Siqun Zhang Kunlun Wang Qiang Xu Yujuan Wang Zhaohui Zhang Guilin Wang Shuai Guo Yi He Yiwei Zhou Zhanji Zhang Libing Yang Wenkang Zou | 2016 | Matter and Radiation at Extremes2016,1,1: | 19 |
| 5 | Simultaneous changes in seed size, oil content and protein content driven by selection of SM/EEIhomologues during soybean domestication显示文摘Soybean accounts for more than half of the global production of oilseed and more than a quarter of the protein used globally for human food and animal feed.Soybean domestication involved parallel increases in seed size and oil content,and a concomitant decrease in protein content.However,science has not yet discovered whether these effects were due to selective pressure on a single gene or multiple genes.Here,re-sequencing data from>800 genotypes revealed a strong selection during soybean domestication on GmSWEETlOa.The selection of GmSWEETlOa conferred simultaneous increases in soybean-seed size and oil content as well as a reduction in the protein content.The result was validated using both near-isogenic lines carrying substitution of haplotype chromosomal segments and transgenic soybeans.Moreover,GmSWEETlOb was found to be functionally redundant with its homologue GmSWEETlOa and to be undergoing selection in current breeding,leading the the elite allele GrnSWEETlOb,a potential target for present-day soybean breeding.Both GmSWEETlOa and GmSWEETlOb were shown to transport sucrose and hexose,contributing to sugar allocation from seed coat to embryo,which consequently determines oil and protein contents and seed size in soybean.We conclude that past selection of optimal GmSWEETlOa alleles drove the initial domestication of multiple soybean-seed traits and that targeted selection of the elite allele GmSWEETlOb may further improve the yield and seed quality of modern soybean cultivars. | Shoudong Wang Shulin Liu Jie Wang Kengo Yokosho Bin Zhou Ya-Chi Yu Zhi Liu Wolf BFrommer Jian Feng Ma Li-Qing Chen Yuefeng Guan Huixia Shou Zhixi Tian | 2020 | National Science Review2020,7,11: | 17 |
| 6 | Genetic variation of yellow pigment and its components in foxtail millet(Setaria italica(L.) P.Beauv.) from different eco-regions in China显示文摘Kernel color is an important trait for assessing the commercial and nutritional quality of foxtail millet.Yellow pigment content(YPC)and carotenoid components(lutein and zeaxanthin)of 270 foxtail millet accessions,including 50 landraces and 220improved cultivars,from four different eco-regions in China were surveyed using spectrophotometry and high performance liquid chromatography methods.Results indicated that YPC had rich variance,ranging from 1.91 to 28.54 mg kg^(–1),with an average value of 17.80 mg kg^(–1).The average YPC of improved cultivars(18.31 mg kg^(–1))was significantly higher than that of landraces(15.51 mg kg^(–1)).The YPC in cultivars from the Loess Plateau spring sowing region(LPSSR)was the highest(20.59 mg kg^(–1)),followed by the North China summer sowing region(NCSSR,18.25 mg kg^(–1)),the northeast spring sowing region(NSSR,17.25 mg kg^(–1)),and the Inner Mongolia Plateau spring sowing region(IMPSSR,13.92 mg kg^(–1)).The variation coefficients of YPC in cultivars from NSSR,LPSSR,and IMPSSR were higher than that from NCSSR.A similar carotenoid profile was also obtained for 270 foxtail millet cultivars.Lutein and zeaxanthin accounted for approximately 55–65%of YPC in accessions.The lutein content was higher than zeaxanthin content in all cultivars.The ratio of lutein to zeaxanthin ranged from 1.51 to 6.06 with an average of 3.34.YPC was positively correlated with lutein(r=0.935,P<0.01),zeaxanthin(r=0.808,P<0.01),and growth duration(r=0.488,P<0.01),whereas it was negatively correlated with grain protein(r=-0.332,P<0.01)and 1 000-kernel weight(r=-0.153,P<0.05).Our study is useful for screening and selecting cultivars with high levels of yellow pigment and for enhancing phytochemical concentrations in breeding programs. | YANG Yan-bing JIA Guan-qing DENG Li-gang QIN Ling CHEN Er-ying CONG Xin-jun ZOU Ren-feng WANG Hai-lian ZHANG Hua-wen LIU Bin GUAN Yan-an DIAO Xian-min YIN Yan-ping | 2017 | Journal of Integrative Agriculture2017,16,11: | 15 |

| 9 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018,61,3: | 12 |
| 10 | Efficacy analysis of flexible neuroendoscopy combined with dry-field techniques in the treatment of chronic subdural hematoma显示文摘Chronic subdural hematoma (CSDH) is a common and frequently occurring disease in neurosurgery, whose incidence accounts for around 10% of all intracranial hematomas. There have been many theories about the mechanism of CSDH, including acute subdural hematoma, slow hemorrhage after bridge vein injury, and traumatic subdural effusion evolution With improvements in medical imaging technology and related basic research, the perception of CSDH as an inflammatory vascular proliferative disease has gradually reached consensus In addition to head trauma, brain atrophy leading to expanded subdural space is the premise and primary reason for the occurrence of CSDH in the older adult population. | Feng Guan Wei-Cheng Peng Hui Huang Bin Dai Guang-Tong Zhu Zhi-Yong Xiao Bei-Bei Mao Zhen-Yang Lin Quan Zhou Ya-Ping Wei Zhi-Qiang Hu | 2019 | Chinese Medical Journal2019,,11: | 12 |

| 13 | Prognostic values of the integrated model incorporating the volume of metastatic regional cervical lymph node and pretreatment serum Epstein-Barr virus DNA copy number in predicting distant metastasis in patients with N1 nasopharyngeal carcinoma显示文摘Background: According to the 7 th edition of the American Joint Committee on Cancer(AJCC) staging system, over50% of patients with nasopharyngeal carcinoma(NPC) have N1 disease at initial diagnosis. However, patients with N1 NPC are relatively under-researched, and the metastasis risk of this group is not well-stratified. This study aimed to evaluate the prognostic values of gross tumor volume of metastatic regional lymph node(GTVnd) and pretreatment serum copy number of Epstein-Barr virus(EBV) DNA in predicting distant metastasis of patients with N1 NPC, and to develop an integrated prognostic model that incorporates GTVnd and EBV DNA copy number for this group of patients.Methods: The medical records of 787 newly diagnosed patients with nonmetastatic, histologically proven N1 NPC who were treated at Sun Yat-sen University Cancer Center between November 2009 and February 2012 were analyzed. Computed tomography-derived GTVnd was measured using the summation-of-area technique. Blood samples were collected before treatment to quantify plasma EBV DNA. The receiver operating characteristic(ROC) curve analysis was used to evaluate the cut-off point for GTVnd, and the area under the ROC curve was used to assess the predicted validity of GTVnd. The survival rates were assessed by Kaplan-Meier analysis, and the survival curves were compared using a log-rank test. Multivariate analysis was conducted using the Cox proportional hazard regression model.Results: The 5-year distant metastasis-free survival(DMFS) rates for patients with GTVnd > 18.9 vs.≤ 18.9 mL were82.2% vs. 93.2%(P < 0.001), and for patients with EBV DNA copy number > 4000 vs. < 4000 copies/mL were 83.5% vs.93.9%(P < 0.001). After adjusting for GTVnd, EBV DNA copy number, and T category in the Cox regression model, both GTVnd > 18.9 mL and EBV DNA copy number > 4000 copies/mL were significantly associated with poor prognosis(both P < 0.05). According to combination of GTVnd and EBV DNA copy number, all patients were divided into low-,moderate-, and high-risk groups, with the 5-year DMFS rates of 96.1,87.4, and 73.8%, respectively(P < 0.001). Multivariate analysis confirmed the prognostic value of this model for distant metastatic risk stratification(hazard ratio [HR],4.17; 95% confidence interval [CI] 2.34-7.59; P < 0.001).Conclusions: GTVnd and serum EBV DNA copy number are independent prognostic factors for predicting distant metastasis in NPC patients with N1 disease. The prognostic model incorporating GTVnd and EBV DNA copy number may improve metastatic risk stratification for this group of patients. | Ji‑Jin Yao Guan‑Qun Zhou Ya‑Qin Wang Si‑Yang Wang Wang‑Jian Zhang Ya‑Nan Jin Fan Zhang Li Li Li‑Zhi Liu Zhi‑Bin Cheng Jun Ma Zhen‑Yu Qi | 2017 | Chinese Journal of Cancer2017,36,12: | 9 |

| 15 | Downward continuation of airborne geomagnetic data based on two iterative regularization methods in the frequency domain显示文摘Downward continuation is a key step in processing airborne geomagnetic data. However,downward continuation is a typically ill-posed problem because its computation is unstable; thus, regularization methods are needed to realize effective continuation. According to the Poisson integral plane approximate relationship between observation and continuation data, the computation formulae combined with the fast Fourier transform(FFT)algorithm are transformed to a frequency domain for accelerating the computational speed. The iterative Tikhonov regularization method and the iterative Landweber regularization method are used in this paper to overcome instability and improve the precision of the results. The availability of these two iterative regularization methods in the frequency domain is validated by simulated geomagnetic data, and the continuation results show good precision. | Liu Xiaogang Li Yingchun Xiao Yun Guan Bin | 2015 | Geodesy and Geodynamics2015,6,1: | 8 |

| 18 | Graphene-enabled electrically controlled terahertz meta-lens显示文摘Metasurfaces have become a new photonic structure for providing potential applications to develop integrated devices with small thickness, because they can introduce an abrupt phase change by arrays of scatterers. To be applied more widely, active metasurface devices are highly desired. Here, a tunable terahertz meta-lens whose focal length is able to be electrically tuned by ~4.45λ is demonstrated experimentally. The lens consists of a metallic metasurface and a monolayer graphene. Due to the dependence of the abrupt phase change of the metasurface on the graphene chemical potential, which can be modulated using an applied gate voltage, the focal length is changed from 10.46 to 12.24 mm when the gate voltage increases from 0 to 2.0 V. Experimental results are in good agreement with the theoretical hypothesis. This type of electrically controlled meta-lens could widen the application of terahertz technology. | WEIGUANG LIU BIN HU ZONGDUO HUANG HONGYU GUAN HETING LI XINKE WANG YAN ZHANG HONGXING YIN XIAOLU XIONG JUAN LIU YONGTIAN WANG | 2018 | Photonics Research2018,6,7: | 8 |
| 19 | Tolerance analysis of multiple-element linear retrodirective cross-eye jamming显示文摘Tolerance sensitivity limits the practical application of the cross-eye jammer.Previous literature has demonstrated that retrodirective cross-eye jamming with multiple antenna elements possesses the advantage of loose tolerance requirements compared to traditional cross-eye jamming.However,the previous analysis was limited,because there are still some factors affecting the parameter tolerance of the multiple-element retrodirective cross-eye jamming(MRCJ)system and they have not been investigated completely,such as the loop difference,the baseline ratio and the jammer-to-signal ratio.This paper performs a comprehensive tolerance analysis of the MRCJ system with a nonuniformspacing linear array.Simulation results demonstrate the tolerance effects of the above influence factors and give reasonable advice for easing tolerance sensitivity. | LIU Tianpeng WEI Xizhang PENG Bo LIU Zhen SUN Bin GUAN Zhiqiang | 2020 | Journal of Systems Engineering and Electronics2020,31,3: | 7 |
