为有效减少隧道突涌水灾害带来的后果损失,提出一种基于序关系分析法(order relation analysis method,G1)-指标相关性权重确定方法(criteria importance through intercriteria correlation,CRITIC)和灰关联矢量投影原理的隧道突涌水灾害的风险评价方法。在调研相关文献和工程实例的基础上,考虑了地层岩性、水文地质、不良地质和施工设计4个方面,构建出一个可量化的隧道突涌水风险评估指标体系;其次,为更好地避免人为因素带来的偏差,采用G1-CRITIC进行主客观赋权,通过引入博弈论得到主客观赋权的组合权重,实现对各评价指标权重的科学合理分配;最后,结合灰关联矢量投影法对隧道涌水风险等级进行定量评价。将该风险评价方法应用于文笔山1#隧道3个洞段样本,对其进行隧道突涌水风险评估,实例结果表明,隧道样本3突涌水风险等级为Ⅳ级,另两个隧道洞段样本为Ⅱ级涌水风险,得出的风险评价等级与实际开挖情况吻合,此模型可对多因素影响下的工程地质灾害进行准确评价,与其他模型结果对比更加验证了该评价模型的可行性与准确性。

Acta Oceanologica Sinica 2015年第5期34卷 12-21页

As the spatio-temporal variability of the Kuroshio is highly influenced by mesoscale eddies, representing its seasonal variability characteristics requires sufficiently long term observations to reduce the uncertainties. Geostrophic velocity data estimated from hydrographic observation from 1987 to 2010 and the shipboard ADCP velocity data from 1993 to 2008 at the PN Section in the central East China Sea are collected to view the seasonal variability objectively. From both types of observation, it is found that the seasonal climatology mean of the Kuroshio Current exhibits significant difference in three areas, which are located at the Kuroshio Current core and its two flanks in a shallow layer less than 300 m, with the weakest northeast current at the core in autumn, the strongest counter current on the right flank in spring, and the strongest northeast current on the left flank in autumn, respectively. The seasonal variance of the Kuroshio Current also exhibits significant difference on the off- shore side of the Kuroshio, with larger variance in spring and summer while smaller variance in autumn and winter. For the current parallel to the PN Section, the ratio of the seasonal variability component to the intraseasonal variability component is relatively smaller than that for the current perpendicular to the PN Section. Further analyses indicate that the seasonal variability at the PN Section is tightly linked to the upstream and downstream current variability.

路径规划旨在为无人机(UAV)提供安全可靠的行进路径,而实际环境的动态性极大地增加了路径规划的难度。本文针对物联网(IoT)节点处的数据收集问题,构建了一个复杂的3D动态环境,在多评论家深度确定性梯度算法(MCDDPG)的基础上提出一种基于无人机电量约束、路径长度最小化(MCDDPG-EPM)算法。算法考虑无人机自身电量约束及其在物联网节点间的调度问题,确保无人机在电量供应安全的前提下以较短的路径长度完成数据采集工作。特别地,为了应对动态环境下突发障碍物移动问题,提出信息增强的概念,以降低移动障碍物带来的路径不确定性。仿真结果表明,当物联网节点数为20时,所提算法相较于双延迟深度确定性策略梯度算法(TD3)、传统A^(*)算法和蚁群算法(ACO)分别节省了11.8%、13.2%和15.1%的电量消耗。

Intracellular ATP is an emerging biomarker for cancer early diagnosis because it is a key messenger for regulating the proliferation and migration of cancer ***,the conventional ATP biosensing strat-egy is often limited by the undesired on-target off-tumor ***,we reported a novel strategy to design enzymatically controlled DNA tetrahedron nanoprobes(En-DT)for biosensing and imaging ATP in tumor *** En-DT was designed via rational engineering of structure-switching aptamers with the incorporation of an enzyme-activatable site and further conjugation on the DNA *** En-DT could be catalytically activated by apurinic/apyrimidinic endonuclease 1(APE1)in cancer cells,but they did not respond to ATP in normal cells,thereby enabling cancer-specific ATP biosensing and imaging in vitro and in vivo with improved tumor *** strategy would facilitate the precise detection of a broad range of biomarker in tumors and may promote the development of smart probes for cancer diagnosis.
