| 1 | Cloud computing for integrated stochastic groundwater uncertainty analysis显示文摘One of the major scientific challenges and societal concerns is to make informed decisions to ensure sustainable groundwater availability when facing deep uncertainties.A major computational requirement associated with this is on-demand computing for risk analysis to support timely decision.This paper presents a scientific modeling service called‘ModflowOnAzure’which enables large-scale ensemble runs of groundwater flow models to be easily executed in parallel in the Windows Azure cloud.Several technical issues were addressed,including the conjunctive use of desktop tools in MATLAB to avoid license issues in the cloud,integration of Dropbox with Azure for improved usability and‘Drop-and-Compute,’and automated file exchanges between desktop and the cloud.Two scientific use cases are presented in this paper using this service with significant computational speedup.One case is from Arizona,where six plausible alternative conceptual models and a streamflow stochastic model are used to evaluate the impacts of different groundwater pumping scenarios.Another case is from Texas,where a global sensitivity analysis is performed on a regional groundwater availability model.Results of both cases show informed uncertainty analysis results that can be used to assist the groundwater planning and sustainability study. | Yong Liu Alexander Y.Sun Keith Nelson Wesley E.Hipke | 2013 | International Journal of Digital Earth2013，6，4： | 3 |

| 9 | 美国农作物育种与农村发展显示文摘农作物育种家为美国农业和经济发展做出了巨大贡献。他们通过提高农业生产效益,改善了农民的经济条件,推动了农村社区的结构调整和发展。自第二次世界大战以来,通过鼓励农业产业化生产模式和补贴政策有力地促进了农业发展和农村生活水平的提高。育种家为农业开发新技术,提供适宜的品种,其主要贡献在于培育适应环境变化和机械化收割、运输的高产作物新品种。随着社会、技术和经济的不断变化,农业生产经营模式不断演化,农村人口不断向外转移。与此同时,多种社会、经济因素促使本土膳食主义、社区农业等新型食品系统模式产生。可持续发展指数反映了大型零售商希望消费者与食品生产之间关系更透明的愿望。这些因素,连同美国对农村生活质量的关注,为育种家解决新的客户需要、开发符合其价值观的技术以及以新的方式服务传统客户提供了机遇。 | 何艳琴 Keith E Woeste Sterling B Blanche Karen A Moldenhaver C Dana Nelson | 2012 | 中国种业2012，，8： | 0 |
