Approximately 20,000 ha of densely built-up areas still remain in Japan. However, the advance of improvements in these areas has been very slow. Thus, making draft improvement plans through citizen-administration partnerships is indispensable to promote improvements. The planning support tool proposed in this study supports a consensus-building process during the creation of draft improvement plans. We develop a disaster mitigation performance evaluation method （DMPEM） for built-up areas at the district level and incorporate this method into a disaster mitigation support Web-GIS. However, DMPEM requires lengthy calculation time because it uses the probabilistic Monte Carlo computation method. Using this tool in realime planning is therefore difficult. In this study, we first develop a system that reduces the calculation time required by DMPEM. Second, the support tool is used to make draft plans through citizen-administration partnerships in districts where residents are conducting various disaster mitigation activities. Finally, we investigate the usefulness of the tool for consensus building through the promotion of lively discussions among residents and clarify the issues associated with practical use of the tool.

Cenozoic basalts from the Linqu County, Shandong Province, China entrain some clinopy- roxene crystals, of which many contain abundant glass melt inclusions. These melt inclusions are ex- tremely irregular in shape with most grain sizes in a range of 10-50 μm and coexist with low-Mg# olivines, labradorites and Ca-rich potassium feldspars. In-situ major and trace element analyses show that the glass melt inclusions are high in alkalis (Na2O+K2O > 10 wt%), SiO2 (>54 wt%), CaO and FeO (>4 wt%), but low in MgO (Mg# 2), thus having phonoli- tic compositions. The compositional features of cli- nopyroxene crystals, glass melt inclusions and their coexistent minerals suggest that these melt inclu- sions were exotic melts in clinopyroxenes trapped prior to their entrainment in the host basalt. The dis- covery of these melt inclusions provides a new ap- proach to further investigating the evolution of Meso- zoic lithospheric mantle beneath the southeastern North China Craton.

Plume-type is a new branch of ophiolite classification introduced by Dilek and Fumes （2011; GSAB, 123,387-）. Its most typical example is the komatiite-basalt-gabbro- wehrlite assemblage that is exposed on the Gorgona Island off Colombia, South America and is interpreted as a part of the Caribbean large igneous province （LIP）. Analogous rock assemblage occur in the accretionary complexes in the circum-Pacific orogenic belts such as in Japan （Ishiwatari and Ichiyama, 2004; Int.

车辆行驶过程中由于受到交通道路以及周围车辆状态等因素影响,常常会被迫换道。例如,在高速公路上行驶的车辆,由于匝道的限制或者交通拥塞等情况,不得不进行换道。车辆换道由于具有随机性或突发性,会影响道路中其他车辆行驶的流畅性。特别是当车辆在高速行驶过程中,换道行为甚至可能引发交通事故。因此,研究车辆的协同换道策略可以降低交通路网中车辆行驶事故发生几率,具有重要的研究意义。针对上述问题,本文利用Stackelberg博弈模型,结合车联网技术,提出了车辆换道策略并设计了相关算法。具体研究内容如下。本论文首先研究了Stackelberg模型,并结合车辆行驶状态设计了收益函数。为了进一步分析收益情况,本文将驾驶员驾驶行为用车辆行驶速度进行描述,并对现有的收益公式进行改进。其中驾驶行为根据车辆行驶速度分为激进型和舒适型。车辆在执行换道前必须计算收益,并根据收益值进行决策。具体操作过程是,每当车辆向前移动时,所有车辆收益值都将根据运动趋势提前进行计算。为了预测周围车辆未来的运动趋势,本文使用了模型预测控制器。此外,本文还将方法分为两个不同的跟车模型,即经典的2秒跟车模型和SUMO交通仿真软件里默认的Krauss跟车模型。针对上述两种跟车模型在换道过程中具体性能和安全性,本文也给出了一定的分析。最后,本文结合Stackelberg模型和模型预测控制器,设计了强制换道策略和对应算法,进而为换道车辆提供合理的换道时间。为了对所提算法进行有效性分析,本文结合SUMO交通仿真软件,进行了相关实验。首先,本文按照参与换道的车辆的数量,设计了三种不同交通流密度的交通仿真场景。针对上述交通场景,本文进行了实验与分析。最后,为了分析具体的效率和性能,本文利用仿真数据,将本文所提算法与其他现有算法进行对比分析,验证了本文算法在仿真场景中具有较好性能。

Three species ofnymphalid butterflies, Vanessa cardui, V. indica and Nymphalis xanthomelasjaponica, do not exhibit seasonal polyphenism in wing coloration. To deter-mine whether seasonal non-polyphenic butterflies possess a cerebral factor affecting wing coloration, we used a Polygonia c-aureurn female short-day pupal assay for detection of summer-morph-producing hormone （SMPH） activity in P. c-aureum. When 2% NaCl extracts of 25 brain-equivalents prepared from the pupal brains of V. cardui, V. indica or N. xanthomelasjaponica were injected into Polygonia female short-day pupae, all recipients developed into summer-morph adults with dark-yellow wings, and the average grade score （AGS） of summer morphs showing SMPH activity was 3.8, 3.7 and 4.0, respectively. In contrast, when acetone or 80% ethanol extracts prepared from pupal brains were injected into Polygonia pupae, all recipients developed into autumn-morph adults with a dark-brown coloration and each exhibited an AGS of less than 0.5. Our results indicate that a cerebral factor showing SMPH activity is present in the pupal brain of seasonal non-polyphenic nymphalid butterflies, suggesting that a SMPH and cerebral factor showing SMPH activity occur widely among butterfly species. This finding will improve our understanding of the presence of cerebral factors showing interspecific actions of SHPH.

To suppress the cavitation in the impellers and to make the turbo-pump lives longer, the inducer was separated from the main impeller and both impellers were driven independently. The performance of the pump and the flow conditions around the impellers were investigated experimentally and the following results were obtained. （1）The main impeller contributes to the flow interaction between the inducer and the main impeller. （2）The rotational speeds of both impellers can be controlled independently in order to suppress simultaneously the cavitation not only in the main impeller, but also in the inducer.

Urban green spaces have been arisen growing concern responded to the social and environmental costs of urban sprawl. A wide range of planning and policies has been and/or will be designed to protect urban green spaces and optimize their spatial pattern. A better design or planning of urban green space can make a major contribution to quality of environment and urban life, and furthermore can decide whether we can have a sustainable development in the urban area. Information about the status quo of urban green spaces can help planners design more effectively. However, how to quantify and capture such information will be the essential question we face. In this paper, to quantify the urban green space, a new method comprising gradient analysis, landscape metrics and GIS was developed through a case of Jinan City. The results demonstrate: 1) the gradient analysis is a valid and reliable instrument to quantify the urban green space spatial pattern precisely; 2) using moving window, explicit landscape metrics were spatially realized. Compared with quantifying metrics in the entire landscape, it would be better to link pattern with process and establish an important basis for analyzing the ecological and socioeconomic functions of green spaces.

Dear Editor,Sperm in patients with obstructive azoospermia （OA） have been retrieved from the reproductive tract and/or from the testis for intracytoplasmic sperm injection （ICSI） in several ways, including microsurgical epididymal sperm aspiration （MESA）, percutaneous epididymal sperm aspiration （PESA）, testicular sperm extraction （TESE）, and other techniques） Each of these has advantages and drawbacks in terms of microsurgical expertise or equipment, number of sperm obtained, invasiveness, and cost. Therefore, we developed a safe, simple, feasible, and low-cost modified MESA technique to collect epididymal sperm under direct vision, which we have labeled macrosurgical epididymal sperm imprint collection （MESIC）. Herein, we present the details of the MESIC technique and our initial experience in patients with suspected OA.
