Here, nine more TGFs of this scenario are reported with concurrent LF sferics and lightning location data. The gamma ray production in these TGFs preceded the occurrence of NBEs by a minimum of 60 µs up to 13.5 ms, and no other fast leader discharge was found within 20 ms before the TGF. The TGF preceded positive NBEs occurred at altitudes of 8.6-11 km in thunderstorms, likely in the high electric field (E field) region of lightning initiation. The analyses show that the NBE preceding TGFs bear harder energy spectrum with larger proportion of high energy photons than EIP related TGFs produced in association with lightning leader. Our findings support the relativistic feedback mechanism of gamma ray generation in the large scale thunderstorm E field.   Effects of dust-in-snow forcing over the Tibetan Plateau on the East Asian dust cycle during the Last Glacial Maximum 期刊论文  OAI收割 PALAEOGEOGRAPHY PALAEOCLIMATOLOGY PALAEOECOLOGY, 2020, 卷号: 542, 页码: 13 作者:  Shen, Jiaojiao;  Xie, Xiaoning;  Cheng, Xugeng;  Liu, Xiaodong   |  收藏  |  浏览/下载：45/0  |  提交时间：2020/06/03 Dust flux  Sensible heat  Anticyclone  Positive feedback  Westerlies  Climatic warming   Morphological traits of submerged macrophytes reveal specific positive feedbacks to water clarity in freshwater ecosystems 期刊论文  OAI收割 SCIENCE OF THE TOTAL ENVIRONMENT, 2019, 卷号: 684, 期号: 1, 页码: 578-586 作者:  Su, Haojie;  Chen, Jun;  Wu, Yao;  Chen, Jianfeng;  Guo, Xiaochun   |  收藏  |  浏览/下载：249/0  |  提交时间：2019/07/30 Regime shifts  Morphological traits  Positive feedback  Water clarity  Submerged macrophyte  Shallow lake   Weakening of the El Nino amplitude since the late 1990s and its link to decadal change in the North Pacific climate 期刊论文  OAI收割 INTERNATIONAL JOURNAL OF CLIMATOLOGY, 2019, 卷号: 39, 期号: 10, 页码: 4125, 4138 作者:  Xu, Kang;  Wang, Weiqiang;  Liu, Boqi;  Zhu, Congwen   |  收藏  |  浏览/下载：55/0  |  提交时间：2019/09/09 Aleutian Low  Bjerknes positive feedback  El Nino  interdecadal change  North Pacific Oscillation   Substrate concentration effect on gene expression in genetic circuits with additional positive feedback 期刊论文  OAI收割 SCIENCE CHINA-TECHNOLOGICAL SCIENCES, 2018, 卷号: 61, 期号: 8, 页码: 1175-1183 作者:  Wu, LuLu;  Wang, Pei;  Lu, JinHu   |  收藏  |  浏览/下载：26/0  |  提交时间：2018/10/07 substrate concentration  additional positive feedback loop  stochastic switch behavior  gene expression  gene differentiation   Impulsive personality dimensions are associated with altered behavioral performance and neural responses in the monetary incentive delay task 期刊论文  OAI收割 NEUROPSYCHOLOGIA, 2017, 卷号: 103, 期号: 0, 页码: 59-68 作者:  Gu, Ruolei;  Jiang, Yang;  Kiser, Seth;  Black, Chelsea L.;  Broster, Lucas S.   |  收藏  |  浏览/下载：50/0  |  提交时间：2017/11/22 Impulsivity  Monetary incentive delay (MID) task  Event-related potential (ERP)  Feedback-related negativity (FRN)  P3 component  Late positive component (LPC)   Global analysis of seagrass restoration: the importance of large-scale planting 期刊论文  OAI收割 JOURNAL OF APPLIED ECOLOGY, 2016, 卷号: 53, 期号: 2, 页码: 567-578 作者:  van Katwijk, MM;  Thorhaug, A;  Marba, N;  Orth, RJ;  Duarte, CM 收藏  |  浏览/下载：37/0  |  提交时间：2016/05/24 allee effect  coastal ecosystems  ecosystem recovery  global restoration trajectories  positive feedback  seagrass mitigation  seagrass rehabilitation
