| 6 | Effects of disinhibition on spatiotemporal pattern of neuronal first recruitment in neuronal networks显示文摘The propagation of neuronal activities is a key feature to understanding information processing in networks. The analysis based on first-spikes of bursts in turn plays an important role in the research of neuronal activity propagation. Our focus here is to investigate how spatiotemporal patterns of neuronal first-spikes are affected by disinhibition. Multi-electrode arrays were used to record stimulation-evoked bursts of multiple neurons in randomly cultured neuronal networks. Both the precise timing of and the rank relationships between first-spikes were analyzed. Compared with evoked bursts in the network's native state, the precise first-spike latencies in its dis-inhibited state are more consistent and the propagation of its bursting activities is much faster. Additional points of interest are that disinhibited neuronal networks can be evoked to generate stable and distinguishable neuronal first recruitment spatiotemporal patterns specific to the stimulation site, and that the disinhibition may cause the original spatiotemporal patterns to change in a heterogeneous manner with regards to different propagation pathways. | Liangbin Pana,b,c,1, Xindong Songa,b,c,1, Guangxin Xiang a,b,c, Jing Zhua,b,c, Jing Cheng a,b,c,d,a Medical Systems Biology Research Center, Tsinghua University School of Medicine, Beijing 100084, China b Department of Biological Sciences and Biotechnology, Tsinghua University, Beijing 100084, China c National Engineering Research Center for Beijing Biochip Technology, 18 Life Science Parkway, Beijing 102206, China d State Key Laboratory of Biomembrane and Membrane Biotechnology, Tsinghua University, Beijing 100084, China | 2009 | Progress in Natural Science:Materials International2009，19，5： | 6 |
| 7 | Enhancing disease resistances of Super Hybrid Rice with four antifungal genes显示文摘A plant expression vector harboring four antifungal genes was delivered into the embryogenic calli of ‘9311’, an indica restorer line of Super Hybrid Rice, via modified biolistic particle bombardment. Southern blot analysis indicated that in the regenerated hygromycin-resistant plants, all the four anti-fungal genes, including RCH10, RAC22, β-Glu and B-RIP, were integrated into the genome of ‘9311’, co-transmitted altogether with the marker gene hpt in a Mendelian pattern. Some transgenic R1 and R2 progenies, with all transgenes displaying a normal expression level in the Northern blot analysis, showed high resistance to Magnaporthe grisea when tested in the typical blast nurseries located in Yanxi and Sanya respectively. Furthermore, transgenic F1 plants, resulting from a cross of R2 homo-zygous lines with high resistance to rice blast with the non-transgenic male sterile line Peiai 64S, showed not only high resistance to M. grisea but also enhanced resistance to rice false smut (a disease caused by Ustilaginoidea virens) and rice kernel smut (another disease caused by Tilletia barclayana). | ZHU HuaChen1, XU XinPing1, XIAO GuoYing2,3, YUAN LongPing2 & LI BaoJian1 1 Biotechnology Research Center, Key Laboratory of Gene Engineering of Ministry of Education, Sun Yat-sen University, Guangzhou 510275, China 2 China National Hybrid Rice R&D Center, Hunan Hybrid Rice Research Center, Changsha 410125, China 3 Institute of Subtropical Agriculture, the Chinese Academy of Sciences, Changsha 410125, China | 2007 | Science China(Life Sciences)2007，50，1： | 6 |
| 8 | Preliminary discussion of low-salinity hydrothermal fluid mineralization显示文摘REVIEWING the history of the geology of mineral deposits, we may find that in the first fifty years of thetwentieth century the magmatic-hydrothermal theory of ore deposition was the most prevalent, whichgave impetus to the development of the geology of mineral deposits. In the 1960s, the drilling of theSalton Sea geothermal field, California, the United States, and discovery and study of the Red Sea seafloor hot brines and large amounts of metal sulfides removed therefrom led to the rise of the brine theory ofmineral deposition, thus elucidating the origin of massive metal sulfides and promoted the discoveryand exploration of metal deposits. After the 1970s and the 1980s, through a study of the hydrothermal ore fluids of modern hotsprings. geologists came to realize that there exist low-salinity hydrothermal ore fluids other than | ZHENG Mianping R & D Center of Saline Lake and Epithermal Deposits, Chinese Academy of Geological Sciences, Beijing 100037, China | 1999 | Chinese Science Bulletin1999，44，S2： | 5 |

| 11 | The influence of impurity on the critical thickness of the CeO_2 buffer layer for coated conductors显示文摘The lattice parameters, band structure, density of state and elastic constant of RE-doped CeO2 (RE=Sm, Gd, Dy), the buffer material for coated HTS conductors, are calculated using the plane-wave method with pseudopotentials based on the density functional theory (DFT) of first-principle. The rule and mechanism of the effect of rare earth impurity on the critical thickness of the CeO2 buffer layer are investigated. It is found that, in the range of the calculation, the changes of the lattice volume V and elastic constant E of CeO2 with the impurity are mainly determined by the increased electrons ne of the system. The relationship of the elastic constant E and increased electrons ne is established. It is indicated that the critical thickness of the CeO2 single buffer layer doped with Sm, Gd, and Dy may be enhanced by 22%, 43% and 33%, respectively. | PAN Min1, HUANG Zheng2, MA HuanFeng2, QIANG WeiRong2, WEI LianFu1, WANG Long2 & ZHAO Yong1,3 1 Key Laboratory of Magnetic Levitation Technologies and Maglev Trains (Ministry of Education of China), Superconductivity R&D Center (SRDC), Southwest Jiaotong University, Chengdu 610031, China 2 School of Physical Science and Technology, Southwest Jiaotong University, Chengdu 610031, China 3 Superconductivity Research Group, School of Materials Science and Engineering, University of New South Wale, Sydney, 2052 NSW, Australia | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，7： | 3 |
| 12 | The effects of K^+ growth conditions on the accumulation of cesium by the bacterium Thermus sp. TibetanG6显示文摘The accumulation of cesium by the bacterium Thermus sp. TibetanG6 was examined under different K+ growth conditions. The effects of external pH and Na+ on the accumulation of ce-sium were also studied, and the mechanism involved was discussed. K+ regimes played an important role in the accumulation of cesium by the strain TibetanG6. The quantity of cesium accumulated (24 h) was much higher in K+-deficient regime than that in K+-sufficient regime. The pH and Na+ had different effects on the accumulation of cesium in the two K+ regimes. IR spectra analyses indicated that the biosorption is a process of homeostasis with cesium initially accumulated on the cell wall. | WANG Hailei1,2,3, KONG Fanjing1,2,3 & ZHENG Mianping1,2,3 1.

| 13 | Development of Temperature-Humidity Independent Control Air-Conditioning Unit for Residential Buildings显示文摘Cooling panels are increasingly used in domestic residential buildings.To provide medium temperature cold water for the cooling panel,and dehumidify the indoor air simultaneously,a new kind of temperature-humidity independent control air-conditioning unit was developed for single residential house by utilizing multi-variable technology.First,the supply air temperature was studied to determine the proper supply air flow rate for the humidity control.Then,the energy consumption of different temperature-humidity independent control systems was studied.The analysis indicates that unity evaporating temperature can be used to handle the moisture load and sensible heat load in two evaporators.So the unit scheme was put forward.Two evaporators were used to produce medium temperature water and dry air separately,and electric expansion valves were used to control the refrigerant distribution between the two evaporators.Then,experimental work was carried out to investigate the influence of compressor frequency,refrigerant distribution on the dehumidification capacity,energy efficiency and refrigeration capacity.In the end,the paper concludes that both compressor frequency and refrigerant distribution can control the dehumidification capacity,but the former influences the EER more than the latter,while the latter influences the refrigeration capacity more than the former.We can find a proper running point at certain sensible and latent cooling load by adjusting both compressor frequency and electric expansion valve.The energy consumption of this kind of unit was estimated and compared with present room air conditioners,which shows that it can save about 41% cooling energy consumption. | HAN Xing1,ZHANG Xu1,LIU Jin-tao2,GAO Si-yun2,KANG Yue2(1.Institute of HVAC & Gas,College of Mechanical Engineering,Tongji University,Shanghai 200092,China 2.Hisense R&D Center,Qingdao,266000,China) | 2009 | 湖南大学学报(自然科学版)2009，36，S1： | 3 |
| 14 | Synthesis, Crystal Structure and Calculated β Value of a Tetrahedral Zinc (II) Complex——Zn(2-NH_2py)_2Br_2显示文摘A new zinc(II) complex, Zn(2-NH2py)2Br2 (py=pyridine), has been synthesized, and its molecular structure has been confirmed by IR, elemental analysis and -ray crystal structure analysis. Its space group is P21/n with Mr=413.43 (C10H12Br2N4Zn), a=7.435(2), b=12.865(3), c=14.186(4)? b=94.08(2)? V=1353.5(5) 3, Z=4, Dc=2.029 g/cm3, F(000)=328, ?2.378mm-1, R=0.0283, wR=0.0501. The total observed reflections with I≥2?I) were 5314, of which the independent reflections were 3106. The complex structure contains a distorted tetrahedron formed by four atoms coordinated to zinc atom, namely two bromide atoms and two nitrogen atoms. The two ZnBr bond lengths within one molecule, 2.3763(6) and 2.4002(5)? respectively, are not equal; and so are the two ZnN bond lengths, which are 2.031(2) and 2.044(2)?respectively. The calculation results using PM3 method through MOPAC software package in Chem 3D show that its first molecular hyperpolarizability b value is 5.210-30esu, which is comparable with that of p-nitroaniline.

| 15 | BATE curve in assessment of clinical utility of predictive biomarkers显示文摘In this paper,for time-to-event data,we propose a new statistical framework for casual inference in evaluating clinical utility of predictive biomarkers and in selecting an optimal treatment for a particular patient.This new casual framework is based on a new concept,called Biomarker Adjusted Treatment Effect (BATE) curve.The BATE curve can be used for assessing clinical utility of a predictive biomarker,for designing a subsequent confirmation trial,and for guiding clinical practice.We then propose semi-parametric methods for estimating the BATE curves of biomarkers and establish asymptotic results of the proposed estimators for the BATE curves.We also conduct extensive simulation studies to evaluate finite-sample properties of the proposed estimation methods.Finally,we illustrate the application of the proposed method in a real-world data set. | ZHOU XiaoHua 1,2,3,& MA YunBei 4,5 1 Northwest HSR&D Center of Excellence,VA Puget Sound Health Care System,Seattle,WA 98198,USA 2 Department of Biostatistics,University of Washington,Seattle,WA 98198,USA 3 Beijing International Center for Mathematical Research,Peking University,Beijing 100871,China 4 Department of Operations Research and Financial Engineering,Princeton University,Princeton,NJ 08540,USA 5 School of Statisitcs,Southwest University of Finance and Economics,Chengdu 611130,China | 2012 | Science China Mathematics2012，55，8： | 2 |
| 16 | Quantitative analysis of Boehm' s GC显示文摘The term garbage collection describes the automated process of finding previously allocated memorythatis no longer in use in order to make the memory available to satisfy subsequent allocation requests. Wehave reviewed existing papers and implementations of GC, and especially analyzed Boehm' s C codes, which isa real-time mark-sweep GC running under Linux and ANSI C standard. In this paper, we will quantitatively an-alyze the performance of different configurations of Boehm' s collector subjected to different workloads. Reportedmeasurements demonstrate that a refined garbage collector is a viable alternative to traditional explicit memorymanagement techniques, even for low-level languages. It is more a trade-off for certain system than an all-or-nothing proposition. | GUAN Xue-tao~*, ZHANG Yuan-rui, GOU Xiao-gang, CHENG Xu (MicroProcessor R & D Center, Peking University, Beijing 100871, China, | 2003 | Journal of Harbin Institute of Technology(New Series)2003，10，3： | 2 |
| 17 | Impact of virus genotype on interferon treatment of patients with chronic hepatitis C: a multicenter controlled study显示文摘BACKGROUND: Some factors have been reported to besassociated with a greater likelihood of sustained viral re-sponse ( SVR) in the interferon (IFN) treatment of chronichepatitis C. The factors include HCV genotype, HCVRNA level in serum, state of liver disease, baseline bodyweight, age, sex, and race. The aim of this trial was to in-vestigate the influence of HCV genotype on the IFN treat-ment of patients with chronic hepatitis C.METHODS: The genotypes of HCV virus were determinedin the patients with chronic hepatitis C from several hospi-tals of China enrolled into the randomized, opened andcontrolled trial of Peg-IFN alpha-2a (pegasys) treatment,controlled with IFN-α-2a (roferon-A). The serum ALTlevels and HCV RNA concentrations of the patients weredetected before and at the end of treatment and during thefollow-up. The influence of HCV genotype on the IFNtreatment of patients with chronic hepatitis C was analyzedin intention-to-treat (ITT) population.RESULTS: The HCV genotypes of 202 patients were deter-mined. Of these patients, 158(78.22%) were infected withgenotype 1 HCV and 44(21.78%) with genotype non-1.The viral response at the end of treatment (ETVR) andsustained viral response (SVR) rates were 53.80% and25.32% respectively in patients with genotype 1 HCV, butthey were 61.36% and 43.18% in patients with genotypenon-1. The difference of SVR between patients with geno-type 1 HCV and those with genotype non-1 was significant(P =0.021). After being grouped by the used drugs, theETVR rates of patients infected with genotype 1 and non-1HCV were 76.83% and 80.95% in the patients treated withpegasys (P =0.686); but their SVR rates were 35.37% and66.67% (P =0. 01). The viral relapse rate of genotype 1HCV (55.56%) was significantly higher than that of geno-type non-1 HCV (23.53%) (P=0.02). In roferon-A group,the ETVR and SVR rates of patients with genotype 1 HCVwere 28.95% and 14.47% respectively, which were lowerbut not more significant than those of patients with geno-type non-1 HCV (43.48% and 21.74%). Moreover, the vi-ral relapse rate of genotype 1 HCV (72.73%) was higherbut not more significant than that of genotype non-1 HCV(50.00%) (P=0.21).CONCLUSION: HCV genotype could affect the efficacies,mainly sustained responses, of IFN treatment in patientswith chronic hepatitis C, and the effects of IFN are relatedto drugs and therapeutic course. | Yao Xie, Dao-Zhen Xu, Zhi-Meng Lu, Kang-Xian Luo, Ji-Dong Jia, Yu-Ming Wang,Gui-Zhen Zhao, Shu-Lin Zhang and Da-Zhi Zhang Department of Infeetious Diseases , Beijing Ditan Hos-pital, Beijing 100011 , China Department of Infec-tious Diseases, Ruijin Hospital, Shanghai 200025, China De-partment of Infectious Diseases, Naifang Hospital, First Military Medical U-niversity, Guangzhou 510515, China (Luo KX) Center of Liver Disease,Beijing Friendship Hospital, Beijing 100050, China (Jia J D ) Institute ofInfectious Disease, Southwest Hospital, Third Military Medical University,Chongqing 410032, China Department of Infectious Disea-ses, Second Hospital, China Medical University, Shenyang 110004, China Department of Infectious Diseases, First Hospital, Xi’ an Jiao-tong University, Xi’ an 710061 , China ) Liver Disease Centerof Chongqing, Second Hospital, Chongqing Medical University,Chongqing 410010, China | 2004 | Hepatobiliary & Pancreatic Diseases International2004，3，3： | 2 |

| 19 | Cesium accumulation by bacterium Thermus sp. TibetanG7:hints for biomineralization of cesium-bearing geyserite in hot springs in Tibet,China显示文摘The bacterium Thermus sp. TibetanG7, isolated from hot springs in Tibet, China, was examined for the ability to accumulate cesium from solutions. Environmental conditions were simulated and the effects of pH, K+, Na+ and K+-regimes were then studied to determine the possible role of the bacterium in the formation of cesium-bearing geyserite around these hot springs. In despite of the inhibition of K+ and Na+, the bacterium Thermus sp. TibetanG7 revealed noticeable accumulation of cesium from solutions, with maximum accumulations of 53.49 and 40.41 μmol Cesium/g cell dry weight in Na+ and K+ inhibition experiments, respectively. The accumulation of cesium by this microorganism is rapid, with 40%―50% accumulated within the first 5 min. K+-deficient cells showed a much higher capacity of cesium accu- mulation compared with K+-sufficient cells. It is evident that the bacteria within the genus thermus play a significant role in the cesium assembly. The formation of cesium-bearing geyserite is also considered. | WANG HaiLei1,2,3, ZHENG MianPing1,2,3 & HUANG XiaoXing4 1 Institute of Mineral Resources, Chinese Academy of Geological Sciences (CAGS), Beijing 100037, China 2 R&D Center for Saline Lake and Epithermal Deposits, CAGS, Beijing 100037, China 3 Open Laboratory of Saline Lake Resourses and Environment, CAGS, Beijing 100037, China 4 Laboratory of Microbial Resources, Institute of Microbiology, Chinese Academy of Sciences, Beijing 100081, China | 2007 | Chinese Science Bulletin2007，52，19： | 2 |
