| 1 | Characterising the nature, evolution and origin of detachment fault in central depression belt, Qiongdongnan Basin of South China Sea: evidence from seismic reflection data显示文摘Using regional geological, newly acquired 2D and 3D seismic, drilling and well log data, especially 2D long cable seismic profiles, the structure and stratigraphy in the deep-water area of Qiongdongnan Basin are interpreted. The geometry of No.2 fault system is also re-defined, which is an important fault in the central depression belt of the deep-water area in the Qiongdongnan Basin by employing the quantitative analysis techniques of fault activity and backstripping. Furthermore, the dynamical evolution of the No.2 fault system and its controls on the central depression belt are analyzed. This study indicates that the Qiongdongnan Basin was strongly influenced by the NW-trending tensile stress field during the Late Eocene. At this time, No.2 fault system initiated and was characterized by several discontinuous fault segments, which controlled a series small NE-trending fault basins. During the Oligocene, the regional extensional stress field changed from NW-SE to SN with the oceanic spreading of South China Sea, the early small faults started to grow along their strikes, eventually connected and merged as the listric shape of the No.2 fault system as observed today. No.2 fault detaches along the crustal Moho surface in the deep domain of the seismic profiles as a large-scale detachment fault. A large-scale rollover anticline formed in hanging wall of the detachment fault. There are a series of small fault basins in both limbs of the rollover anticline, showing that the early small basins were involved into fold deformation of the rollover anticline. Structurally, from west to east, the central depression belt is characterized by alternatively arranged graben and half-graben. The central depression belt of the Qiongdongnan Basin lies at the extension zone of the tip of the V-shaped northwestern ocean sub-basin of the South China Sea, its activity period is the same as the development period of the northwestern ocean sub-basin, furthermore the emplacement and eruption of magma that originated from the mantle below the Moho surface occurred at the region between Songnan-Baodao and Changchang sags, from east to west with the early-stage spreading of the South China Sea. Therefore, this study not only helps in depicting the structural features and evolution of the deep-water basin in the Qiongdongnan Basin, but also provides the geological and structural evidence for establishing a unified model of continental margin extension and oceanic spreading. | REN Jianye ZHANG Daojun TONG Dianjun HUANG Anmin WANG Yahui LEI Chao ZUO Qianmei ZHAO Yanghui HE Weijun YANG Linlong | 2014 | Acta Oceanologica Sinica2014，33，12： | 8 |
| 2 | Seismic Reflection Characteristics and Evolution of Intrusions in the Qiongdongnan Basin: Implications for the Rifting of the South China Sea显示文摘The Qiongdongnan Basin(QDNB) is situated in the extensional zone at the vertex of the V-shaped northwest sub-basin, non-volcanic northern margin of the South China Sea(SCS). From north to south, the thickness of the continental lithosphere decreases from 22 km on the northern continental shelf to 17 km at the deepest area of the central depression. A sharp change on the crustal structure is of importance to hydrocarbon exploration yet the dynamic causes remain unknown. A comprehensive study including (1) interpretation of seismic profiles,(2) P-wave velocity data modeling, and (3) magnetic anomalies analysis reveals that there are some high-density intrusions along the lithospheric thinning belt. Chaotic reflections can be found in the southwest of the QDNB, with a low velocity(<3.4 km/s), while in the center and the east, the intensively deformed strata passing towards the diapir flanks and their high velocities(>6 km/s) suggest the existence of igneous diapirs. Diapirism differentiation are primarily achieved through analysis of the contact relationship and the thickness variations in the surrounding strata. The first phase of diapirism along the Songnan low uplift occurred in the Late Mesozoic, and the second phase of diapirism in a form of subsequent gas movement remained active until the Late Quaternary. The distribution and the evolution of the diapirs would have major implications for post-rift emplacement. | Yanghui Zhao Dianjun Tong Ying Song Linlong Yang Chao Huang | 2016 | Journal of Earth Science2016，27，4： | 8 |
| 3 | Quantitative Analysis of Faults in Huizhou Sub-basin, Pearl River Mouth Basin显示文摘This study used 2 D seismic profiles to investigate the Cenozoic evolution of faults in the Huizhou Sub-basin. It aims to define the basin structure style through describing the geometric features of the faults and quantitatively analyzing their activities. The results indicate that the boundary faults in the Huizhou Sub-basin display en echelon arrangement in plan view, which indicates that, it was caused by a kind of oblique extension. Calculating the fault slips shows long-term activities of faults occurred in the basin, and some boundary faults kept active after 5.5 Ma. The evolution history of the fault system is reconstructed. Initially, during the Eocene–Early Oligocene, mainly NNE-NE and NW trending faults and NE striking grabens and half-grabens formed in the basin and a series of faults system controlled the deposition. During the Late Oligocene–Early Miocene, the structural activities were relatively weak, the fault activity and the fault growth rate decreased sharply. Finally, in the late stage from Late Miocene to the present, the structure movement was re-activated, and some faults were also reactivated. Our study will help better understand the structural features and evolution of the petroleum-bearing basins in the northern margin of the South China Sea. | Boubacar Hamidou Leyla Junxia Zhang Linlong Yang | 2018 | Journal of Earth Science2018，29，1： | 2 |
| 4 | Enhancing cartilage repair with optimized supramolecular hydrogel-based scaffold and pulsed electromagnetic field显示文摘Functional tissue engineering strategies provide innovative approach for the repair and regeneration of damaged cartilage.Hydrogel is widely used because it could provide rapid defect filling and proper structure support,and is biocompatible for cell aggregation and matrix deposition.Efforts have been made to seek suitable scaffolds for cartilage tissue engineering.Here Alg-DA/Ac-β-CD/gelatin hydrogel was designed with the features of physical and chemical multiple crosslinking and self-healing properties.Gelation time,swelling ratio,biodegradability and biocompatibility of the hydrogels were systematically characterized,and the injectable self-healing adhesive hydrogel were demonstrated to exhibit ideal properties for cartilage repair.Furthermore,the new hydrogel design introduces a pre-gel state before photo-crosslinking,where increased viscosity and decreased fluidity allow the gel to remain in a semi-solid condition.This granted multiple administration routes to the hydrogels,which brings hydrogels the ability to adapt to complex clinical situations.Pulsed electromagnetic fields(PEMF)have been recognized as a promising solution to various health problems owing to their noninvasive properties and therapeutic potentials.PEMF treatment offers a better clinical outcome with fewer,if any,side effects,and wildly used in musculoskeletal tissue repair.Thereby we propose PEMF as an effective biophysical stimulation to be 4th key element in cartilage tissue engineering.In this study,the as-prepared Alg-DA/Ac-β-CD/gelatin hydrogels were utilized in the rat osteochondral defect model,and the potential application of PEMF in cartilage tissue engineering were investigated.PEMF treatment were proven to enhance the quality of engineered chondrogenic constructs in vitro,and facilitate chondrogenesis and cartilage repair in vivo.All of the results suggested that with the injectable self-healing adhesive hydrogel and PEMF treatment,this newly proposed tissue engineering strategy revealed superior clinical potential for cartilage defect treatment. | Yucong Li Linlong Li Ye Li Lu Feng Bin Wang Ming Wang Haixing Wang Meiling Zhu Yongkang Yang Erik IWaldorff Nianli Zhang Ingmar Viohl Sien Lin Liming Bian Wayne Yuk-Wai Lee Gang Li | 2023 | Bioactive Materials2023，，4： | 1 |
| 5 | 一种用于淮河上游日径流预测的增强型LSTM模型显示文摘径流预报对防洪具有重要意义。然而,由于径流过程的复杂性和随机性,对日径流量进行准确预测是困难的,尤其是对峰值径流量的预测。为了解决这一问题,本研究提出了一种用于径流预测的增强型长短期记忆(LSTM)模型,其中引入了新的损失函数并集成了特征提取器。设计了峰值误差tanh(peak error tanh,PET)和峰值误差swish(peak error swish,PES)两个损失函数,增强了峰值径流预测的重要性,弱化了正常径流预测的权重。为每个气象站建立由3个LSTM网络组成的特征提取器,目的是提取每个气象站输入数据的时间特征。以中国淮河上游为例,利用增强型LSTM模型对1960—2016年的日径流量进行了预测。结果表明,改进后的LSTM模型表现良好,在验证期内(2005年11月至2016年12月),Nash-Sutcliffe效率(NSE)系数在0.917-0.924之间,优于广泛使用的集总水文模型(Australian Water Balance model(AWBM)、Sacramento、Sim Hyd和Tank模型)和数据驱动模型(人工神经网络(ANN)、支持向量回归(SVR)和门控循环单元(GRU))。以PES为损失函数的增强型LSTM对洪水极端径流的预测效果最好,平均NSE为0.873。此外,海拔较高的气象站降水对径流预测的贡献比最近的气象站更大。该研究为流域日径流预测提供了有效工具,有利于流域防洪和水安全管理。 | Yuanyuan Man Qinli Yang Junming Shao Guoqing Wang Linlong Bai Yunhong Xue | 2023 | Engineering2023，，5： | 0 |
| 6 | O-alg-THAM/gel hydrogels functionalized with engineered microspheres based on mesenchymal stem cell secretion recruit endogenous stem cells for cartilage repair显示文摘Lacking self-repair abilities,injuries to articular cartilage can lead to cartilage degeneration and ultimately result in osteoarthritis.Tissue engineering based on functional bioactive scaffolds are emerging as promising approaches for articular cartilage regeneration and repair.Although the use of cell-laden scaffolds prior to implantation can regenerate and repair cartilage lesions to some extent,these approaches are still restricted by limited cell sources,excessive costs,risks of disease transmission and complex manufacturing practices.Acellular approaches through the recruitment of endogenous cells offer great promise for in situ articular cartilage regeneration.In this study,we propose an endogenous stem cell recruitment strategy for cartilage repair.Based on an injectable,adhesive and self-healable o-alg-THAM/gel hydrogel system as scaffolds and a biophysio-enhanced bioactive microspheres engineered based on hBMSCs secretion during chondrogenic differentiation as bioactive supplement,the as proposed functional material effectively and specifically recruit endogenous stem cells for cartilage repair,providing new insights into in situ articular cartilage regeneration. | Yucong Li Linlong Li Ming Wang Boguang Yang Baozhen Huang Shanshan Bai Xiaoting Zhang Nan Hou Haixing Wang Zhengmeng Yang Chong Tang Ye Li Wayne Yuk-Wai Lee Lu Feng Micky D.Tortorella Gang Li | 2023 | Bioactive Materials2023，，10： | 0 |
| 7 | Structural Variability and Rifting Process of the Segmented Cenozoic Pearl River Mouth Basin,Northern Continental Margin of the South China Sea显示文摘The Pearl River Mouth Basin(PRMB)is an important area for studying the evolution of continental marginal basins in the northern South China Sea(SCS),but the structural variability and spatiotemporal rifting process remains poorly understood.This study investigates the differential structural features of the eastern,middle and western PRMB,as well as the extensional deformation laws in operation during the rifting stage,according to an integrated analysis of geometric characteristics and kinematic parameters,i.e.,horizontal displacement and stretching factors of basin and crust.The PRMB underwent at least three phases of intense extension,which varied in time and space.(1)During the middle Eocene,most sags in the PRMB were intensely stretched and high-angle planar to listric boundary faults controlled the wedge-shaped stratigraphic geometry.(2)During the late Eocene-to-early Oligocene,the stratigraphic geometry of the sags was slightly wedge-shaped and continuously controlled by boundary faults,however,the extensional strength decreased relatively in the Northern depression zone,but increased in the Southern depression zone.(3)During the late Oligocene,the extension was extremely weak in the northeast PRMB,but relatively strong in the southwest PRMB,leading to tabular stratigraphic geometry in the northeast PRMB,but localized slightly wedge-shaped stratigraphic geometry in the southwest.The southwest PRMB still underwent relatively strong extension during the early Miocene.The southwest PRMB that was induced by a small-scale localized mantle convection system constantly rifted during the late Oligocene,controlled by the weak lithosphere,westward(southwestward)diachronous opening and southward jump of the ocean ridge.The applied quantitative parameters and spatiotemporal rifting process may be used as a reference with which to study the segmented continental margin rifts. | MA Bingshan QI Jiafu WU Guanghui REN Jianye YANG Linlong SUN Tong CHEN Shi CHEN Weichang GE Jiawang | 2022 | Acta Geologica Sinica(English Edition)2022，96，6： | 0 |
