Thousands of lakes on the Tibetan Plateau(TP) play a critical role in the regional water cycle, weather, and climate. In recent years, the areas of TP lakes underwent drastic changes and have become a research hotspot. However, the characteristics of the lake-atmosphere interaction over the high-altitude lakes are still unclear, which inhibits model development and the accurate simulation of lake climate effects. The source region of the Yellow River(SRYR) has the largest outflow lake and freshwater lake on the TP and is one of the most densely distributed lakes on the TP. Since 2011,three observation sites have been set up in the Ngoring Lake basin in the SRYR to monitor the lake-atmosphere interaction and the differences among water-heat exchanges over the land and lake surfaces. This study presents an eight-year(2012–19), half-hourly, observation-based dataset related to lake–atmosphere interactions composed of three sites. The three sites represent the lake surface, the lakeside, and the land. The observations contain the basic meteorological elements,surface radiation, eddy covariance system, soil temperature, and moisture(for land). Information related to the sites and instruments, the continuity and completeness of data, and the differences among the observational results at different sites are described in this study. These data have been used in the previous study to reveal a few energy and water exchange characteristics of TP lakes and to validate and improve the lake and land surface model. The dataset is available at National Cryosphere Desert Data Center and Science Data Bank.

目的了解和分析上海市嘉定区胃癌患者在选择就医至确诊为胃癌的影响因素。方法收集2013年1月至2018年4月上海交通大学附属瑞金医院北院接受外科胃癌根治术患者共589例的临床资料。调查患者的主诉、学历、有无医保、常住地址、发病年龄、就医后选择是否为胃镜检查方式对患者确诊为胃癌的影响。并采用χ2检验、多因素Logistic回归模型等方法进行统计学分析。结果 589例患者及时就诊的影响因素包括患者是否存在报警症状(即主诉)及常住地址(与就诊医院的距离)(P <0. 05)。患者来院就诊后选择下一步接受胃镜检查,或是坚持服药缓解症状,则与患者主诉、是否有医保、常住地址、发现症状及时就医与否有关(P <0. 05)。患者首次就医至确诊时间的长短,与患者的主诉、常住地址、就医后是否选择胃镜检查方式相关(P <0. 05)。Logistic回归分析显示,主诉(OR=1. 550,95%CI:1. 346～1. 784)、有无医保(OR=1. 942,95%CI:1. 023～3. 686)是胃癌确诊及时性的危险因素。而发病年龄(OR=0. 970,95%CI:0. 947～0. 994)、常住地址(OR=1. 699,95%CI:1. 519～1. 943)、就医后选择方式(OR=1. 010,95%CI:1. 052～1. 128)是胃癌确诊及时性的保护因素。结论患者出现症状、就诊、确诊为胃癌的及时性,与患者有无医保、不适主诉、常住地址等密切相关。

Field studies were conducted to examine the effects of cerium on the growth and physiological characteristics of Cyclocarya paliurus seedlings by spraying the foliage with different concentrations of cerium nitrate. Optimal concentrations of cerium nitrate improved the relative growth yield of seedling height and stems and the soluble protein and sugar content of the leaves. Cerium nitrate also increased the concentration of secondary metabolites including triterpenoids, quercetin and kaempferol, mineral elements K, P, Mg, Mn, Fe and Cu, and the activities of superoxide dismutase （SOD）, peroxidase （POX）, and phenylalanine ammonia-lyase （PAL） in the leaves. The effects of cerium nitrate on these indices were dose dependent. A concentration of 0.20 mmol/L was optimal to promote the relative growth yield of seedling height, contents of soluble sugar, kaempferol, K, P, Cu, and activities of PAL, SOD, and POX, significantly increased by 54.61%, 14.71%, 55.19%, 105.2%, 74.5%, 133.3%, 80.48%, 25.35% and 22.54%, respectively, as compared with the control. However, the maximal increase in relative growth yield of stems, contents of triterpenoid, quercetin, Mg, Mn, and Fe was attained at 1.00 mmol/L treatment, which significantly increased by 87.00%, 80.56%, 452.44%, 93.2%, 29.4%, and 133.9%, respectively, compared with control check （CK）. Correlation analysis revealed positive relationships between activities of PAL, SOD and contents of triterpenoid, quercetin and kaempferol within a certain concentration range of cerium nitrate. These resuits suggested that an appropriate concentration of cerium not only was effective in the improvement of physiological function of C. paliurus, but also increased seedling resistance. Moreover, it stimulated the synthesis of medicinal components in leaves.

证据权重法评价模型作为一个客观的系统,它可以对不同因素的权重值进行计算,且分配权重过程客观,可以区分不同因素对于崩塌敏感性的影响。为了了解不同因素对崩塌的敏感性,本文利用已经发生的崩塌灾害的信息,以湖北省巴东县沿渡河镇为例,选取了106个崩塌点,采用证据权重法,通过ArcGIS软件对坡度、坡向、到断层的距离、到水系的距离、到公路的距离以及地层岩性等6个基本因素进行了敏感性分析,其中随机选取78个崩塌点作为训练集用来建模,另外28个崩塌点作为测试集对评价结果进行检测。分析结果表明:在影响崩塌的6个因子中,崩塌点到公路的距离的敏感性最大;崩塌敏感性高的区域呈线性分布在道路及河流附近,极高敏感区和高敏感性区占整个研究区的15.27%,测试集中有22个崩塌点分布在该区域内,即78.58%的崩塌点被正确评价,与现场调查结果相吻合,所得到的崩塌敏感性图对于防灾减灾工作具有指导作用。

A wide range of morphological and physiological traits have changed between cultivated rice Oryza sativa and wild rice Oryza rufipogon under domestication. Here, we report cloning of the An-2 gene, encoding the Lonely Guy Like protein 6 （OsLOGL6）, which catalyzes the final step of cytokinin synthesis in O. rufipogon. The near-isogenic line harboring a wild allele of An-2 in the genetic background of the awnless indica Guangluai 4 shows that An-2 promotes awn elongation by enhancing cell division, but decreases grain production by reducing grains per panicle and tillers per plant. We reveal that a genetic variation in the An-2 locus has a large impact on reducing awn length and increasing tiller and grain numbers in domesticated rice. Analysis of gene expression patterns suggests that An-1 reg- ulates the formation of awn primordial, and An-2 promotes awn elongation. Nucleotide diversity of the An-2 locus in cultivated rice was found to be significantly reduced compared with that of wild rice, suggesting that the An-2 locus was subjected to artificial selection. We therefore propose that the selection of genetic variation in An-2 was due to reduced awn length and increased grain yield in cultivated rice.
