Extensive mass transport deposits（MTDs）, which form a significant component of the stratigraphic record in ancient and modern deep water systems, mostly distributed in the continental margin of ocean basins worldwide. To date, no large-scale MTDs have been found in Chinese terrestrial basins. Based on integrated analysis of the seismic, drilling, core and logging data, this article report MTDs have been found in Songliao terrestrial basin（SLTB）, Northeast China. During the depositional period of the Upper Cretaceous Qingshankou Formation, slope break of lacustrine basins was an ideal discharge place for gravity depositions. Regional sedimentary study of MTDs reveals that Cretaceous-age MTDs in SLTB were deposited in slope-break environments by slide, slump and debris flow, and MTDs were mixed with little turbidite simultaneously. Besides the massive aspect, key features of MTDs are the common presence of deformational structures or softsedimentary deformation, floating shale clasts, boudins, microfaults, distortion beddings, rotated sand debris. Detailed mapping of two three-dimensional（3-D） seismic surveys acquired in Yingtai（YT） and Haituozi（HTZ） areas reveals that MTDs are characterized by chaotic, mounded, and transparent seismic reflection. Growth fault, slope gully and geomorphology of the slope break greatly influenced the sedimentary process and external geometry of MTDs, and as a consequence, MTDs in SLTB exhibit classic fan-like geometry and some special（non-fan-like） external geometry. Furthermore, fanlike MTDs can be divided into three subcategories, including isolated fan, mother-son fan and stacked fan. Non-fan-like MTDs can be divided into two subcategories, strip-like MTDs and faulted-pit MTDs. A new sedimentary model has been built for MTDs in SLTB. MTDs have become a new exploration and development target in the SLTB.

Neural Regeneration Research 2011年第16期6卷 1243-1247页

作者： shuxin Wang Dengji pan Na Liu Yongming Liu Juan Chen Houjie Ni Zhouping Tang Department of Neurology Tongji Hospital Tongji Medical College Huazhong University of Science and Technology Wuhan 430030 HubeiProvince China

Previous studies have demonstrated that differentiated neural stem cells （NSCs） are more suitable for transplantation than non-differentiated NSCs. In this study, NSCs were expanded in vitro for two passages, induced with retinoic acid to differentiate, and harvested between 1 6 days later. They were subsequently cultured in artificial cerebrospinal fluid for an additional 3 days, dudng which their growth and morphology was monitored. NSCs induced for 4 days exhibited a peak rate of cells differentiating into neurons and robust growth. Our results indicate that the optimal time point for transplanting NSCs is following a 4-day period of induced differentiation.

河流在洪水期携带大量陆源碎屑,当其入湖或入海后,由于洪水密度大于周围水体的密度,洪水发生下沉并沿盆地底部长距离运移,形成陆源下潜流或异重流。异重流形成的相关沉积岩被统称为异重岩。异重岩通常由一个底部的反粒序单元和一个顶部的正粒序单元组成,反粒序单元反映了异重流能量的逐渐增强,正粒序反映了流体能量的逐渐减弱。异重流以3种方式搬运碎屑颗粒,即底载搬运、悬浮搬运和漂浮搬运。根据搬运方式的不同,异重岩分为3类岩相,即底载成因的B类岩相、悬载成因的S类岩相和漂浮物成因的L类岩相。异重流的沉积充填形成了河道、堤岸和朵叶体3类微相,内部岩相变化极为发育。异重岩的沉积特征虽然典型且较易识别,但是常被误认为是砂质碎屑流、滨岸相、三角洲相或河流相沉积。

The H5N8 avian influenza viruses have been widely circulating in wild birds and are responsible for the loss of over 33 million domestic poultry in Europe, Russia, Middle East, and Asia since January 2020. To monitor the invasion and spread of the H5N8 virus in China, we performed active surveillance by analyzing 317 wild bird samples and swab samples collected from 41,172 poultry all over the country. We isolated 22 H5N8 viruses from wild birds and 14 H5N8 viruses from waterfowls. Genetic analysis indicated that the 36 viruses formed two different genotypes: one genotype viruses were widely detected from different wild birds and domestic waterfowls;the other genotype was isolated from a whopper swan. We further revealed the origin and spatiotemporal spread of these two distinct H5N8 virus genotypes in 2020 and 2021. Animal studies indicated that the H5N8 isolates are highly pathogenic to chickens, mildly pathogenic in ducks, but have distinct pathotypes in mice. Moreover, we found that vaccinated poultry in China could be completely protected against H5N8 virus challenge. Given that the H5N8 viruses are likely to continue to spread in wild birds, vaccination of poultry is highly recommended in high-risk countries to prevent H5N8 avian influenza.

企业通常会通过权衡应计盈余管理和真实盈余管理的边际收益和成本来确定盈余管理的方式和水平。金税三期系统以智能化为特征,有效实现了税收信息整合,能够充分发挥强化税收监管的作用,提高企业真实盈余管理的税收成本,但不影响应计盈余管理成本,从而改变企业盈余管理的选择。文章以各地区实施金税三期作为外生事件构造双重差分检验,研究了智能化税收监管对企业盈余管理选择的影响。研究结果表明,金税三期强化了对纳税不遵从企业的监管,增加了企业实施真实盈余管理的税收成本,使得纳税不遵从企业倾向于增加应计盈余管理,而且随着税率的上升,应计盈余管理和真实盈余管理的替代关系增强。文章的研究为理解企业盈余管理行为和制定税收监管政策提供了启示。
