| 1 | 利用多尺度CT成像表征致密砂岩微观孔喉结构显示文摘为全面表征致密储集层微观孔喉分布及结构特征,对鄂尔多斯盆地上三叠统延长组致密砂岩储集层样品进行纳米—微米多尺度CT三维成像研究。首先利用低分辨率微米尺度X-CT扫描获取直径为2.54 cm岩心柱内部微米级别孔喉结构特征,然后根据微孔分布特征,制备多个直径为65μm的样品进行高分辨率纳米尺度扫描,重构纳米级微孔三维结构模型,最终计算出样品的孔隙度和渗透率。在微米尺度下,孔喉大小不一,直径为5.4~26.0μm,呈孤立状,局部呈条带状;在纳米尺度下,微孔直径主要为0.4~1.5μm,纳米级微孔数量增多,孔喉为管状、球状,分布于矿物颗粒(晶体)内部或表面。纳米级球状微孔连通性较差,三维空间呈孤立状,多仅作为储集空间,而纳米级短管状微孔具有一定的连通性,与微米级管状微孔和邻近孤立球状纳米微孔具有一定连通性,兼具喉道与孔隙的双重功能。数值计算样品渗透率为0.843×10 3μm2,孔隙度为10%。 | 白斌 朱如凯 吴松涛 杨文静 Jeff Gelb Allen Gu 张响响 苏玲 | 2013 | 石油勘探与开发2013，40，3： | 165 |
| 2 | Optical observations of LIGO source GW 170817 by the Antarctic Survey Telescopes at Dome A,Antarctica显示文摘The LIGO detection of gravitational waves(GW) from merging black holes in 2015 marked the beginning of a new era in observational astronomy. The detection of an electromagnetic signal from a GW source is the critical next step to explore in detail the physics involved. The Antarctic Survey Telescopes(AST3),located at Dome A, Antarctica, is uniquely situated for rapid response time-domain astronomy with its continuous night-time coverage during the austral winter. We report optical observations of the GW source(GW 170817) in the nearby galaxy NGC 4993 using AST3. The data show a rapidly fading transient at around 1 day after the GW trigger, with the i-band magnitude declining from 17:23 ± 0:13 magnitude to 17:72 ± 0:09 magnitude in ~1:8 h. The brightness and time evolution of the optical transient associated with GW 170817 are broadly consistent with the predictions of models involving merging binary neutron stars. We infer from our data that the merging process ejected about ~10^(-2) solar mass of radioactive material at a speed of up to 30% the speed of light. | lei hu xuefeng wu igor andreoni michael c.b.ashley jeff cooke xiangqun cui fujia du zigao dai bozhong gu yi hu haiping lu xiaoyan li zhengyang li ensi liang liangduan liu bin ma zhaohui shang tianrui sun n.b.suntzeff charling tao syed a.uddin lifan wang xiaofeng wang haikun wen di xiao jin xu ji yang shihai yang xiangyan yuan hongyan zhou hui zhang jilin zhou zonghong zhu | 2017 | Science Bulletin2017，62，21： | 6 |
| 3 | 干旱胁迫的水稻根高效酵母双杂交体系建立显示文摘采用SMART技术在酵母菌株AH109中构建了干旱胁迫下水稻根部全长cDNA文库,采用改进的滤膜杂交方法建立了高效酵母杂交体系,以抗旱相关水稻转录调控因子OsWRKY71基因作为诱饵对该方法进行检验。实验获得的酵母杂交文库容量为4.9×106,平均插入片段为800bp,达到了基因分离和克隆等后续研究的标准。同时采用滤膜杂交法将文库的杂交效率提高到了6.9%,是液体杂交法的6倍以上。该方法不需要特殊的设备,且具有低消耗和高效率的特点,可用于高通量酵母双杂交分析。 | 付坚 Linkun GU 郭怡卿 Liyuan ZHANG 王玲仙 李定琴 王波 Jeff Qingxi SHEN 程在全 | 2013 | 中国水稻科学2013，27，2： | 2 |
| 4 | 西加拿大沉积盆地中的水力压裂和地震活动显示文摘绝大多数非常规油气资源的开发有赖于向地下注入大量的液体,这可能使附近断层活动从而诱发地震。在过去5年里,加速的油田注水已经导致北美部分地区的地震频率急剧增加。在美国中部,大多数诱发地震起因于与油气开采相伴生的废水的排放。形成对比的是,在加拿大西部,大多数最近的诱发地震在时间和空间上与水力压裂高度相关,在水力压裂过程中,为诱发局部岩石破裂,在钻井结束的过程中,高压液体被注入。并且,与水力压裂相关的观测到的最大地震震级似乎超越了预测的、经常引用的注入液体体积与最大期望震级之间的关系。这些发现对评估诱发地震危害具有深远的意义。 | Gail M.Atkinso David W.Eaton Hadi Ghofrani Dan Walker Burns Cheadle Ryan Schultz Robert Shcherbakov Kristy Tiampo Jeff Gu Rebecca M.Harrington Yajing Liu Mirko van der Baan Honn Kao 张汨 | 2018 | 国际地震动态2018，0，10： | 1 |
| 5 | Genetic Evidence for XPC-KRAS Interactions During Lung Cancer Development显示文摘Lung cancer causes more deaths than breast, colorectal and prostate cancers combined. Despite major advances in targeted therapy in a subset of lung adenocarcinomas, the overall 5-year survival rate for lung cancer worldwide has not significantly changed for the last few decades. DNA repair deficiency is known to contribute to lung cancer development. In fact, human polymorphisms in DNA repair genes such as xeroderma pigmentosum group C(XPC) are highly associated with lung cancer incidence. However, the direct genetic evidence for the role of XPC for lung cancer development is still lacking. Mutations of the Kirsten rat sarcoma viral oncogene homolog(Kras) or its downstream effector genes occur in almost all lung cancer cells, and there are a number of mouse models for lung cancer with these mutations. Using activated Kras, Kras LA1, as a driver for lung cancer development in mice, we showed for the first time that mice with Kras LA1 and Xpc knockout had worst outcomes in lung cancer development, and this phenotype was associated with accumulated DNA damage. Using cultured cells, we demonstrated that induced expression of oncogenic KRAS G12 V led to increased levels of reactive oxygen species(ROS) as well as DNA damage, and both can be suppressed by anti-oxidants. Our results suggest that XPC may help repair DNA damage caused by KRAS-mediated production of ROS. | Xiaoli Zhang Nonggao He Dongsheng Gu Jeff Wickliffe James Salazar Istavan Boldogh Jingwu Xie | 2015 | Journal of Genetics and Genomics2015，42，10： | 1 |
| 6 | Mandatory IFRS adoption and management forecasts: The impact of enforcement changes显示文摘We examine how concurrent enforcement changes affect the positive relationship between mandatory IFRS adoption and firms’ voluntary disclosure. We show that the increase in the issuance of management forecasts after IFRS adoption is smaller for firms from IFRS-mandating countries with concurrent enforcement changes than for those from countries without such changes. We find no difference in the increase of forecast informativeness between firms from IFRS-mandating countries without concurrent enforcement changes and firms from non-IFRS-mandating countries; however, firms domiciled in IFRS-mandating countries with concurrent enforcement changes exhibit a significantly smaller increase in forecast informativeness. Our findings suggest that better IFRS enforcement distinctly weakens (strengthens) the positive effect of IFRS adoption on voluntary (mandatory) disclosure. | Zhaoyang Gu Jeff Ng Albert Tsang | 2019 | China Journal of Accounting Research2019，，1： | 0 |
