Magnetic sensorless sensing experiments of the plasma horizontal positionhave been carried out in the superconducting tokamak HT-7. The horizontal position is calculatedfrom the vertical field coil current and voltage without using signals of magnetic probes placednearby a plasma. The calculations are focused on the ripple frequency component of the power *** is no drift problem with the time integration of magnetic probe signals. The error of thederived plasma position is lower than 2% of the plasma minor radius.

长期以来,我国在黄土高原重点产沙区,小、中、大流域的水文特征进行了动态监测,取得了大量的宝贵资料,这些信息对于有关部门和广大科研人员研究土壤侵蚀规律,以及为水土保持治理决策与措施配置提供科学依据起到重要作用。但由于已往研究手段的限制,以地貌特征(包括以土地利用方式)变化的动态检测缺乏系统研究。以地貌形态特征、土地利用方式的变化的动态检测,对于有关部门更加全面的认识地表剥蚀过程、人类活动的影响,提供了水沙检测替代不了的作用,是相关研究的重要内容之一。随着航天遥感、计算机软件技术的不断提高,将三维动态的地貌、土地利用方式与土壤侵蚀的过程相结合是交叉学科的重要研究方向。根据5期晋西王家沟小流域(从1959～1999)大比尺航片,在高程数字化模型(DEM)、正射影像图(DOM)制作的基础上,开展了40年来,以地貌特征并结合小流域水沙变化为目标的动态检测,为地貌演化、地表剥蚀过程研究提供了基础信息。

Objectives: The goal was to assess the risk factors for emergency cesarean section versus prophylactic caesarean section. Materials and Methods: This was a descriptive analytical cross-sectional study of the Type cas/Witnesses at the Reference Health Centre of Commune V of the District of Bamako in Mali. The sample consisted of 100 cases for 200 controls (1 case for 2 controls) with retrospective collection of data for the period from January 1 to July 11, 2011 (6 months and 11 days). Results: During the study period, out of a total of 3559 deliveries, we recorded 2,794 vaginal deliveries, 78.50% and 765 caesarean sections or 21.50%. Of the 765ceras, we performed 353 emergency caesarean sections or 46.15% and 412 prophylactic caesarean sections 53.85%. We have selected 100 prophylactic caesarean section files and 200 emergency caesarean section files. The average age of the patients was 27.41 years-5.84 with extreme ages of 14 to 40 years. 100% of our patients (cas) had performed at least one antenatal consultation compared to 83.5% of the parturients evacuated (Witnesses). The most frequently cited reasons for evacuation were: acute fetal suffering, non-cephalic presentation and excessive uterine height with 30%, 17.5% and 12% respectively. The bulk of the caesarean section indications were dominated by dystocies with 90% in cases compared to 65% in Witnesses, followed by acute fetal suffering with 30% in Witnesses. We recorded 30% perinatal deaths among Witnesses compared to 1% in cases. We recorded 16 uterine ruptures in the Witnesses among which 2 hysterectomies and 14 hystererraphia. Conclusion: Prophylactic caesarean section improves maternal and perinatal prognosis more than emergency caesarean section.

基于气候生产力模型,利用1960～2000年127个气象站气温、降水资料以及植被信息,对云南省自然植被净初级生产力的时空分布特征进行了分析。结果表明:41a云南自然植被年均NPP为4.23×108tDM/a,约占全国自然植被年均NPP总量的11.4%;单位面积的平均NPP为10.64tDM/(hm2·a),是全国平均水平的2.8倍。云南自然植被NPP随着纬度、经度和海拔高度的增加均呈现下降趋势,变化总趋势为北部<中部<南部,东部<中部<西部。云南自然植被NPP在干季(11～4月)和雨季(5～10月)差异显著,6～8月最大;41a来云南大部分地区自然植被NPP呈现上升趋势,20世纪70、80年代比60年代有所下降,90年代有所上升。气温增加,降水增加或不变的情况下,滇西北和滇东北NPP增加幅度大于其他地区,说明这些地区气温是制约自然植被NPP的主要因素;气温增加,降水减少的情况下,几个少雨区和多雨区NPP降低幅度大于其他地区,表明在上述地区限制NPP的主要因素是水分。

针对使用分布式线性弥散码的放大转发协同中继网络,提出一种基于MAC层请求发送/允许发送协议的分布式功率分配方案。此方案不需要处理中心集中处理后反馈信息,信源和各中继节点可以计算自己的优化发射功率,简单易实现。还从降低系统中断概率的角度给出了基于中继信道强度的瓶颈效应和调和平均值的两种发射功率分配算法。仿真结果表明,相比较传统的等功率分配,提出的方案充分体现了分布式线性弥散码的分集增益,不仅降低系统的中断概率,还大大改善了接收端的误码率性能,有很强的实用性。

Studies of e^+e~→D_s^+■^((*)0)K^-and the P-wave charmed-strange mesons are performed based on an e^+e^-collision data sample corresponding to an integrated luminosity of 567 pb^(-1) collected with the BESIII detector at s^(1/2)=4.600 GeV. The processes of e^+e^-→D_s^+■^(*0)K^- and D_s^+■~0K^- are observed for the first time and are found to be dominated by the modes D_s^+D_(s1)(2536)^-and D_s^+D_(s2)~*(2573)^-, respectively. The Born cross sections are measured to be σ~B(e^+e^-→D_s^+■^(*0)K^-) =(10.1±2.3±0.8) pb and σ~B(e^+e^-→D_s^+■~0K^-) =(19.4±2.3± 1.6) pb, and the products of Born cross section and the decay branching fraction are measured to be σ~B(e^+e^-→D_s^+D_(s1)(2536)^-+c.c.)·B(D_(s1)(2536)^-→■^(*0)K^-)=(7.5±1.8±0.7) pb and σ~B(e^+e^-→D_s^+D_(s2)~*(2573)^-+ c.c.)·B(D_(s2)~*(2573)^-→■~0 K^-)=(19.7 ± 2.9 ±2.0) pb. For the D_(s1)(2536)^-and D_(s2)~*(2573)^-mesons, the masses and widths are measured to be M(D_(s1)(2536)^-)=(2537.7±0.5 ±3.1) MeV/c2, Γ(D_(s1)(2536)^-) =(1.7 ±1.2 ±0.6)MeV, and M(D_(s2)~*(2573)^-)=(2570.7±2.0 ±1.7) MeV/c^2, Γ(D_(s2)~*(2573)^-)=(17.2 ±3.6 ±1.1) MeV. The spin-parity of the D_(s2)~*(2573)^-meson is determined to be J^p= 2^+. In addition, the processes e^+e^-→D_s^+■^((*)0)K^-are searched for using the data samples taken at four(two) center-of-mass energies between 4.416(4.527) and 4.575 GeV, and upper limits at the 90% confidence level on the cross sections are determined.
