| 1 | Growth response and toxic effects of three antibiotics on Selenastrum capricornutum evaluated by photosynthetic rate and chlorophyll biosynthesis显示文摘The effects of three types of antibiotics (erythromycin,ciprofloxacin and sulfamethoxazole) on the photosynthesis of freshwater algae,Selenastrum capricornutum Printz,were investigated by determining the growth rate,chloroplast pigments content,seven main precursors (including δ-aminolevulinic acid,porphobilinogen,uroporphyrinogen III,coproporphyrinogen III,protoporphyrin IX,Mg-proporphyrin IX and protochlorophyllide),and photosynthetic rate during chlorophyll biosynthesis.The antibiotics significantly decreased the growth rate,chlorophyll content,and photosynthetic rate.Erythromycin induced a decreasing effect at a concentration of 0.06 mg/L,while ciprofloxacin and sulfamethoxazole achieved the same results at concentrations higher than 1.5 mg/L.Only erythromycin significantly inhibited chlorophyll biosynthesis,which indicated that it was considerably more toxic to S.capricornutum than ciprofloxacin and sulfamethoxazole,and may pose a high potential risk to aquatic ecosystems. | Binyang Liu Weiqiu Liu Xiangping Nie Chao Guan Yufeng Yang Zhaohui Wang Wei Liao | 2011 | Journal of Environmental Sciences2011，23，9： | 11 |
| 2 | Protective effects of recombinant human growth hormone on cirrhotic rats显示文摘AIM: To investigate the effects and molecular mechanismsof recombinant human growth hormone (rhGH) onprotecting liver function and alleviating portal hypertensionof liver cirrhotic rats.METHODS: Liver cirrhosis of male Sprague-Dawley ratswas induced by administration of thioacetamide. The ratswith or without liver cirrhosis were randomly divided intofour groups. Group A consisted of the normal rats wastreated with normal saline (NS), group B consisted of thenormal rats was treated with rhGH, group C consisted ofcirrhotic rats was treated with NS, and group D consistedof cirrhotic rats was treated with rhGH. The rats of differentgroups were subcutaneously injected with 0.5 mL of NS or333 ng/kg of rhGH daily for 7 d. After treatments, thefollowing parameters were examined, including GH-bindingcapacity (RO by 12SI-hGH binding, growth hormone receptormRNA(GHR mRNA) expression by RT-PCR, relative contentof collagen (RCC) by histomorphomertry, and level ofmalon-dialdehyde (MDA) and superoxide dismutase (SOD)in liver tissue by thiobarbituric acid reaction and pyrogallicacid self-oxidation, respectively. Serum albumin (ALB),alanine transaminase (ALT) and portal vein pressure (PVP)were also examined.RESULTS: rhGH up-regulated both the GH-binding capacity(R0 and the expression of GHR mRNA in vivo. RT in groupA (72+12 fmol/mg protein) was significantly higher thanthat in group C (31+4 fmol/mg protein) (P<0.05). RT ingroup B (80+9 fmol/mg protein) increased markedlycompared to group A (P<0.05). RT in group D (40+7 fmol/mgprotein) raised remarkably compared with group C (P<0.05),but less than that in group A, and there was no significantGH binding affinity contrast (Kd) change. The GHR mRNAlevel (iOD, pixel) in group A (29+3) was significantly higherthan that in group C (23+3) (P<0.05). GHR mRNA levelswere significantly raised in group B (56+4) and group D(42+8) compared with groups A and C (29+3 and 23+3,respectively) (P<0.05). Compared with the normal liver,MDA level was higher and SOD level was lower in cirrhoticlivers. After rhGH treatment, MDA level was significantlydeclined to 12.0+2.2 nmol/mg protein and SOD was raisedto 1029+76 U/rag protein in group D (P<0.05). ALB levelsin groups B and D (42+7 g/L and 37+7 g/L, respectively)were significantly raised compared with those in groups Aand C (35+5 g/L and 29+4 g/L, respectively) (P<0.05).ALT level was markedly lower in group D (69+7 U/L)compared to group C (89+15 U/L) (P<0.05), and close togroup A (61+10 U/L). RCC in group C (22.30+3.86%) wassignificantly higher than that in group A (1.14+0.21%) andgroup D (14.70+2.07%) (P<0.05). In addition, rhGHmarkedly alleviated portal hypertension in liver cirrhoticrats (group D vsC, 9.3+1.5 cmH20 vs 14.4+2.0 cmH20)(P<0.05).CONCLUSION: Pharmacological doses of rhGH canincrease RT and GHR mRNA expression, ameliorate liverfunctions, repress fibrosis and decline portal hypertension,suggesting it has potentially clinical usage as a hepatotropicfactor. | ShuangChen Hong-TaoWang BinYang Yu-RuFu Qing-JiaOu | 2004 | World Journal of Gastroenterology2004，10，19： | 7 |
| 3 | Experimental study on the effects of HP and LP EGR on thermal efficiency and emissions of a two-stage turbocharged diesel engine显示文摘An experimental study was performed to compare the effects of high-and low-pressure exhaust gas recirculation loops(HP and LP EGR loops)on thermal efficiency and emissions of a diesel engine.Tests were conducted on a 12-L six-cylinder turbocharged diesel engine under various operating conditions.We found that at a low speed of 1100 r/min,1 MPa BMEP,the LP EGR loop could achieve higher brake thermal efficiency and lower emissions than the HP EGR.This is because the lower enthalpy available at the turbine inlet of the HP EGR loop increased the fuel/oxygen equivalence ratio.For the HP EGR,the gross indicated thermal efficiency was reduced by 1%,but pumping losses were only reduced by 0.5%,compared to the LP EGR loop.At a higher speed of 1600 r/min,1 MPa BMEP,the HP EGR loop attained a higher brake thermal efficiency and lower emissions because of the relatively sufficient flow through the turbocharger.For the HP EGR loop,the gross indicated thermal efficiency was only reduced by 0.5%and pumping losses were reduced by 1.5%,compared to the LP EGR loop.Lower fuel consumption and a longer ignition delay made the distribution of fuel/oxygen equivalence ratio more homogeneous,leading to lower emissions.Our data also showed that at the high speed of 1600 r/min,0.55 MPa BMEP,the brake thermal efficiency of the HP EGR loop first increased,then decreased as the EGR rate increased.Therefore,under all conditions,a reasonable match of both EGR loops could achieve a good balance between fuel consumption and emissions of NOx and soot. | WU BinYang PU YouZhe YU XiaoYang SU WanHua | 2014 | Science China(Technological Sciences)2014，57，2： | 6 |
| 4 | Isothermal grain growth of reactive spray formed 7075 alloys in semi-solid state显示文摘The grain growth behavior in reactive spray formed 7075+2.91vol%TiC Al alloy was studied and compared with that of spray formed 7075 Al alloy at semi-solid state. The effects of in-situ TiC particles on the microstructure of spray formed 7075 Al alloy were also investigated. The specimens were heat-treated isothermally at various temperatures between the solidus and liquidus of 7075 Al alloy for times in the range of 10-60 min, then quenched in water. The microstructure of reheated specimens was characterized using scanning electron microscopy and optical microscopy. The grain size was measured using a mean linear intercept method.Results show that the in-situ TiC particles can effectively retard grain growth and refine the grain at a limited size. The grain growth exponent in Arrhenius equation increases from 2 to 3, which indicates that the in-situ TiC particles have the significant pinning effect on grain coarsening in the semi-solid state. | HuiminLiu HuaCuit BinYang JishanZhang | 2004 | Journal of University of Science and Technology Beijing2004，11，5： | 5 |
| 5 | An Attention-Based Neural Framework for Uncertainty Identification on Social Media Texts显示文摘Uncertainty identification is an important semantic processing task. It is crucial to the quality of information in terms of factuality in many applications, such as topic detection and question answering. Factuality has become a premier concern especially in social media, in which texts are written informally. However, existing approaches that rely on lexical cues suffer greatly from the casual or word-of-mouth peculiarity of social media, in which the cue phrases are often expressed in substandard form or even omitted from sentences. To tackle these problems, this paper proposes an Attention-based Neural Framework for Uncertainty identification on social media texts, named ANFU. ANFU incorporates attention-based Long Short-Term Memory(LSTM) networks to represent the semantics of words and Convolutional Neural Networks(CNNs) to capture the most important semantics. Experiments were conducted on four datasets, including 2 English benchmark datasets used in the CoNLL-2010 task of uncertainty identification and 2 Chinese datasets of Weibo and Chinese news texts. Experimental results showed that our proposed ANFU approach outperformed the-state-of-the-art on all the datasets in terms of F1 measure. More importantly, 41.37% and 13.10% improvements were achieved over the baselines on English and Chinese social media datasets, respectively, showing the particular effectiveness of ANFU on social media texts. | Xu Han Binyang Li Zhuoran Wang | 2020 | Tsinghua Science and Technology2020，25，1： | 5 |

| 8 | Experimental study on the deformation and failure mechanism of overburden rock during coal mining using a comprehensive intelligent sensing method显示文摘Understanding the spatiotemporal evolution of overburden deformation during coal mining is still a challenge in engineering practice due to the limitation of monitoring techniques. Taking the Yangliu Coal Mine as an example, a similarity model test was designed and conducted to investigate the deformation and failure mechanism of overlying rocks in this study. Distributed fiber optic sensing(DFOS), highdensity electrical resistivity tomography(HD-ERT) and close-range photogrammetry(CRP) technologies were used in the test for comprehensive analyses. The combined use of the three methods facilitates the investigation of the spatiotemporal evolution characteristics of overburden deformation, showing that the mining-induced deformation of overburden strata was a dynamic evolution process. This process was accompanied by the formation, propagation, closure and redevelopment of separation cracks.Moreover, the key rock stratum with high strength and high-quality lithology played a crucial role in the whole process of overburden deformation. There were generally three failure modes of overburden rock layers, including bending and tension, overall shearing, and shearing and sliding. Shear failure often leads to overburden falling off in blocks, which poses a serious threat to mining safety. Therefore, realtime and accurate monitoring of overburden deformation is of great significance for the safe mining of underground coal seams. | Gang Cheng Wentao Xu Bin Shi Jinghong Wu Binyang Sun Honghu Zhu | 2022 | Journal of Rock Mechanics and Geotechnical Engineering2022，14，5： | 2 |

| 14 | A Filter-Based Uniform Algorithm for Optimizing Top-k Query in Distributed Networks显示文摘In this paper we propose a Filter-based Uniform Algorithm (FbUA) for optimizing top-k query in distributed networks, which has been a topic of much recent interest. The basic idea of FbUA is to set a filter at each node to prevent it from sending out the data with little chance to contribute to the top-k result. FbUA can gain exact answers to top-k query through two phrases of round-trip communications between query station and participant nodes. The experiment results show that FbUA reduces network bandwidth consumption dramatically. | ZHAO Zhibin YAO Lan YANG Xiaochun LI Binyang YU Ge | 2006 | Wuhan University Journal of Natural Sciences2006，11，5： | 1 |
