2Studies on the regional feature of organic carbon in sediments off the Huanghe River Estuary waters显示文摘Organic carbon (OC) in definitely small area sediments(according to marine dimension)off the Huanghe River Estuary is investigated in order to evaluate the feature of regional difference of physical and chemical properties in marginal sea sediments.The distributions of OC in sediments with natural grain size and the relationship with the pH,Eh ,Es and Fe3+/Fe2+ are discussed.In addition,OC decomposition rates in surfacial/subsurfacial sediments are estimated.OC concentrations range from 0.26% to 1.8%(wt)in the study area. Significant differences in OC content and in horizontal distribution as well as various trends in surfacial /subsurfacial sediments exhibit the feature of regional difference remarkably in marginal sea sediments. The complicated distribution of OC in surface sediments is due to the influence of bacterial activity and abundance, bioturbation of benthos and physical disturbance. The OC decomposition rate constant in surfacial /subsurfacial sediments ranges from 0.009 7 to 0.076 a-1 and the relatively high values may be mainly related to bacteria that are mainly responsible for OC mineralization;meio-and macrofauna affect OC degradation both directly, through feeding on it, and indirectly through bioturbation and at the same time coarse sediments are also disadvantageous to OC preservation.In almost all the middle and bottom sediments the contents of OC decrease with the increase of deposition depth, which indicates that mineralization of OC in the middle and bottom sediments has occurred via processes like SO reduction and Fe-oxide reduction.YUANHuamao LIUZhigang SONGJinming LüXiaoxia LIXuegang LINing ZHANTianrong 2004Acta Oceanologica Sinica2004,23,1:8
3Dissolved inorganic carbon and CO_(2) fluxes across Jiaozhou Bay air-water interface显示文摘On the basis of data collected in the Jiaozhou Bay in June and July 2003, the DIC distribution in seawater is studied,and an average air-sea flux of CO2 is estimated. The results show that the content of DIC inside the bay is markedly higher than outside the bay in June, but the content of DIC outside the bay is markedly higher than inside the bay in July. The trend of DIC distribution inside the bay is similar, viz. the content is the maximum in the northeast, then decreases gradually toward the west, and the content is the minimum in the west. The total trend of vertical distribution is to increase gradually from surface to bottom. This characteristic of DIC distribution is determined by Jiaozhou Bay hydrology and there is a close relation between DIC and particulate N,P. Average CO2flux across the source for atmospheric CO2 in June and July, and the total CO2 flux from seawater into atmosphere is about 740 t in June and 969 t in July.LIXuegang LINing GAOXuelu SONGJinming 2004Acta Oceanologica Sinica2004,23,2:8
4Production of transgenic calves by somatic cell nuclear transfer显示文摘Bovine fetal oviduct epithelial cells were transfected with constructed double marker selective vector(pCE-EGFP-IRES-Neo-dNdB) containing the enhanced green fluorescent protein (EGFP) and neomycin-resistant(Neo^r) genes by electroporation, and a transgenic cell line was obtained. Somatic cell nuclear transfer (SCNT) was cartied out using the transgenic cells as nuclei donor. A total of 424 SCNT embryos were reconstructed and 208 (49.1%) of them developed to blastocyst stage. 17 blastocysts on D 7 after reconstruction were transferred to 17 surrogate calves,and 5 (29.4%) recipients were found to be pregnant. Three of them maintained to term and delivered three cloned calves.PCR and Southern blot analysis confirmed the integration of transgene in all of the three cloned calves. In addition, expression of EGFP was detected in biopsy isolated from the transgenic cloned calves and fibroblasts derived from the biopsy. Our results suggest that transgenic calves could be efficiently produced by SCNT using transgenic cells as nuclei donor. Furthermore, all cloned animals could be ensured to be transgenic by efficiently pre-screening transgenic cells and SCNT embryos using the constructed double marker selective vector.GONGGuochun DAIYunping FANBaoliang ZHUHuabing WANGLili WANGHaiping TANGBo LIUYing LIRong WANGRong HUANGYinghua LINing 2004Chinese Science Bulletin2004,49,2:7
5Characteristics of nitrogen forms in the southern Huanghai Sea surface sediments显示文摘The distributions of different forms of nitrogen in the surface sediments of the southern Huanghai Sea are different and affected by various factors. The contents of IEF-N, SOEF-N and TN gradually decrease eastward, and those of SAEF-N northward, while those of WAEF-N westward. Around the seaport of the old Huanghe (Yellow) River, the contents of both SOEF-N and TN are the highest. Among all the factors, the content of fine sediment is the predominant factor to affect the distributions of different forms of nitrogen. The contents of IEF-N, SOEF-N, and TN have visibly positive correlation with the content of f'me sediments, and the correlative coefficient is 0.68, 0.58 and 0.71 respectively, showing that the contents of the three forms of nitrogen increase with those of f-me sediments. The content of WAEF-N is related to that of fine sediments to a certain extent, with a correlative coefficient of 0.35; while the content of SAEF-N is not related to that of fine sediments, showing that the content of SAEF-N is not controlled by fine grain-size fractions of sediments. In addition, the distributions of different forms of nitrogen are also interacted one another, and the contents of IEF-N and SOEF-N are obviously affected by TN, while those of inorganic nitrogen (WAEF-N, SAEF-N and IEF-N) are not affected by SOEF-N and TN obviously, although they are interacted each other.LüXiaoxia SONGJinming LIXuegang YUANHuamao ZHANTianrong LINing GAOXuelu 2004Acta Oceanologica Sinica2004,23,3:7
6A formal semantics for program debugging显示文摘This work aims to build a semantic framework for automated debugging.A debugging process consists of tracing,locating,and fixing processes consecutively.The first two processes are accomplished by a tracing procedure and a locating procedure,respectively.The tracing procedure reproduces the execution of the failed test case with well-designed data structures and saves necessary information for locating bugs.The locating procedure will use the information obtained from the tracing procedure to locate ill-designed statements and to generate a system of fix-equations,whose solution will be used to fix the bugs.A structural operational semantics is given to define the functions of the tracing and locating procedures.Both of them are proved to terminate.The main task of fixing process is to solve the fix-equations.It turns out that for a given failed test case,there exist four types of fix-equations and three dierent solutions:1)The bug is solvable,i.e.,there exists a solution of the system of fix-equations,and the program can be repaired.2)There exists a structural design error in the program,i.e.,the system of fix-equations generated at each round of the locating procedure is solvable,but a new bug will arise when the old bug is being fixed.3)There exists a logical design error,and the system of fix-equations is not solvable.LI Wei LINing 2012Science China(Information Sciences)2012,55,1:4

8Study on Properties of Magnesia-Hercynite Brick显示文摘Using magnesia and hercynite as materials, we researched the magnesia hercynite brick in order to solve the problem of chrome free brick used in the burning zone of cement rotary kiln. Effect of different firing temperature and different content of hercynite on properties of the brick were studied. The results show that the magnesia hercynite specimen fired at 1600℃ was densified and when the hercynite content is 7%, the cold crushing strength and the adhesive strength of rupture of the specimen have the highest value.LIUHuilin LINing LIQiang 2005China's Refractories2005,14,2:4
9A 6.2–9.5 GHz receiver for Wimedia MB-OFDM and China UWB standard显示文摘An integrated 6.2–9.5 GHz UWB receiver for both WiMedia MB-OFDM and China UWB standard is proposed. The receiver can cover Group#3, Group#4 for WiMedia and Group#2–5 for China UWB standard respectively. The fully differential receiver consists of a wideband LNA and a down conversion mixer with high gain and low gain mode. A low-pass filter with controllable gain and cut-o? frequency along with a programmable gain amplifier are also included. The chip was fabricated in TSMC 0.13-μm RF CMOS process. Measurement results show that the receiver achieves voltage gain from 21 to 69 dB with 2 dB/step and an NF of 3.2–4.6 dB over 6.2–9.5 GHz and 1-dB compression point of ?21 dBm. The intermediate frequency of the receiver can be switched between 264 and 132 MHz, which enables the receiver applicable for both WiMedia and China UWB standard. Power consumption is only 47 mA with 1.2–V supply voltage.GAO Ting ZHOU Feng LI Wei LAN Fei LINing REN JunYan 2011Science China(Information Sciences)2011,54,2:4
10Modification of magnetic properties in SmCo films by controlling crystallization and phase transition显示文摘A series of Cr/SmCo/Cr films with high Sm concentration(37.7at%) were prepared by magnetron sputtering.Effects of SmCo thickness,annealing temperature,and annealing time on magnetic properties and crystal structure were carefully studied.Results show that crystallization degree and phase transition in the films can be controlled by the SmCo thickness and optimized by properly increasing the annealing temperature and extending the annealing time.Finally,a SmCo film with high magnetic properties and low MEI was constructed.FENG Chun LINing LI Shuai HUO QianMing LI MingHua ZHAN Qian LI BaoHe JIANG Yong YU GuangHua 2012Science China(Physics,Mechanics & Astronomy)2012,55,10:3

12Property of the Constant Modulus Algorithm to Capture the Weak Signal显示文摘The Constant Modulus Algorithm (CMA) enjoys widespread popularity as methods for blind beamforming and equalization of communication signals.CMA is straightforward to implement,robust,and computationally of moderate complexity. Furthermore, it is insensitive to array imperfection.In an environment containing multiple constant modulus signals,the signal extracted by CMA depends on the relative power of the incident signals. According previous works,the CMA is prone to capture the strongest Constant Modulus(CM) signal at the output of the array.In this paper,we show that the weak CM signal could be recovered by CMA 1-2 and CMA 2-1 when setting special step-size.Simulation examples confirm our remarks.LINing GUOYan GUOLi 2003The Journal of China Universities of Posts and Telecommunications2003,10,1:3

15A current-mode RF transmitter for 6–9 GHz MB-OFDM UWB application显示文摘This paper presents a current-mode 6–9 GHz RF transmitter for MB-OFDM UWB systems. The proposed current-mode transmitter consists of current-mode IQ LPF, current mirror amplifier, IQ up-conversion mixer (up-mixer), differential power driver amplifier (PA) and high-speed divider with LO buffers for generating IQ LO signals. All circuits are designed to possess high linearity and wide bandwidth. The transmitter is fabricated in TSMC 0.13 μm 1P8M RF CMOS technology with a die area of 1.56 mm2. Measurement results show that a maximum output power of -0.7 dBm with an LO leakage/sideband rejection ratio (LOL/SB RR) around -33/ - 35 dBc is achieved, and that this transmitter excels the traditional voltage-mode counterpart in terms of high linearity (about +1 dBm output 1-dB compression point, +10 dBm output IP3 in average) with comparable power consumption (drawing 48 mA current from 1.2 V supply).CHEN YunFeng FAN JinHan LI Wei LINing REN JunYan 2011Science China(Information Sciences)2011,54,2:2
16Expression of recombinant human lysozyme in the milk of transgenic mice显示文摘Human lysozyme is a 130-aa (amino acid) alka-line polypeptide, and has both anti-bacterial and anti-viral properties which make it an important component of human natural immunity system. As a first step toward the ultimate goal of improving the anti-bacterial properties of bovine and ovine milk, a transgenic mouse that contains the genomicDNA sequence of the human lysozme gene has been gener-ated for the first time. From 83 mice generated by microin-jection, a total of 6 positive transgenic mice were identified by PCR and Southern blot. F1 mice positive for transgene inlines were also detected by PCR. This shows that transgene could be transmitted from founder transgenic mice to their offspring. Recombinant human lysozyme (rHlys) was found in the whey of 3 female positive transgenic mice by Western blot. The highest concentration of rHlys for transgenic mice was 0.2 mg/mL. The antibacterial activity of the whey fortransgenic mice was highly enhanced up to 0.4 times as much as that of human, while that of non-transgenic mouse wasvery low. Although the lysozyme activity of transgenic mice is still lower than that of human, the rHlys exhibits the same specific activity as that of human lysozyme. It provides astrong basis for further studies into the possible application of rHlys express in mammary gland.YUZhengquan FANBaoliang DAIYunping ZHENGMing MINHuiling WANGMeili WANGLili FEIJing LINing 2003Chinese Science Bulletin2003,48,21:2
