| 1 | Frozen subduction in the Yangtze block:insights from the deep seismic profiling and gravity anomaly in east Sichuan fold belt显示文摘The Sichuan basin is the main part of the middle-upper Yangtze block, which has been experienced a long-term tectonic evolution since Archean. The Yangtze block was regarded as a stable block until the collision with the Cathaysia block in late Neoproterozoic. A new deep seismic reflection profile conducted in the eastern Sichuan fold belt(ESFB) discovered a serials of south-dipping reflectors shown from lower crust to the mantle imply a frozen subduction zone within the Yangtze block. In order to prove the speculation, we also obtain the middle-lower crustal gravity anomalies by removing the gravity anomalies induced by the sedimentary rocks and the mantle beneath the Moho, which shows the mid-lower crustal structure of the Sichuan basin can be divided into eastern and western parts. Combined with the geochronology and Aeromagnetic anomalies, we speculated the Yangtze block was amalgamated by the West Sichuan and East Sichuan blocks separated by the Huayin-Chongqing line. The frozen subduction zone subsequently shifted to a shear zone accommodated the lower crustal shortening when the decollement at the base of the Nanhua system functioned in the upper plate. | Xiaosong Xiong Rui Gao Haiyan Wang Jisheng Zhang Lianghui Guo | 2016 | Earthquake Science2016，29，2： | 7 |
| 2 | The Deep Structure Feature of the Sichuan Basin and Adjacent Orogens显示文摘The basin-mountain system in the Sichuan Basin(SCB) reflects the main tectonic activity and the orogenic denudation in this region. The seismic probing work reveals the deep structure of the basin-mountain system. The seismic work was re-sampled to the Moho depth and the sedimentary thickness as well as the P-wave velocity-depth function to analyze the deep structure of the SCB and adjacent orogens. The results show two deposit centers in the SCB: the Deyang area in the west and the Nanchuan area in the east and depression uplift exists in the southwestern part of the SCB; the Moho shallowers gradually from the west to east(ca. 62-36 km deep),the South-North seismic belt(SNSB) is very distinctive: the Moho depth is much shallower(< 50 km)to the east of the SNSB, whereas it is much deeper(>50 km)to the west of the SNSB, suggesting that the SNSB rather than the Longmen Shan tectonic belt is a main Moho transition belt; the topography and the top interface of the basement have the same undulation trend when the sedimentary thickness and the Moho depth have a mirror relationship; the low velocity zone developed in the Kangdian thrust and fold belt and Songpan-Garzê belt implied a soft, weak and thick crust there showing tectonic activity in these areas. | XIONG Xiaosong GAO Rui GUO Lianghui WANG Haiyan JIANG Zhuwei | 2015 | Acta Geologica Sinica(English Edition)2015，89，4： | 3 |

| 4 | Poly-dopamine, poly-levodopa, and poly-norepinephrine coatings: Comparison of physico-chemical and biological properties with focus on the application for blood-contacting devices显示文摘Thanks to its simplicity,versatility,and secondary reactivity,dopamine self-polymerized coatings(pDA)have been widely used in surface modification of biomaterials,but the limitation in secondary molecular grafting and the high roughness restrain their application in some special scenarios.Therefore,some other catecholamine coatings analog to pDA have attracted more and more attention,including the smoother poly-norepinephrine coating(pNE),and the poly-levodopa coating(pLD)containing additional carboxyl groups.However,the lack of a systematic comparison of the properties,especially the biological properties of the above three catecholamine coatings,makes it difficult to give a guiding opinion on the application scenarios of different coatings.Herein,we systematically studied the physical,chemical,and biological properties of the three catecholamine coatings,and explored the feasibility of their application for the modification of biomaterials,especially cardiovascular materials.Among them,the pDA coating was the roughest,with the largest amount of amino and phenolic hydroxyl groups for molecule grafting,and induced the strongest platelet adhesion and activation.The pLD coating was the thinnest and most hydrophilic but triggered the strongest inflammatory response.The pNE coating was the smoothest,with the best hemocompatibility and histocompatibility,and with the strongest cell selectivity of promoting the proliferation of endothelial cells while inhibiting the proliferation of smooth muscle cells.To sum up,the pNE coating may be a better choice for the surface modification of cardiovascular materials,especially those for vascular stents and grafts,but it is still not widely recognized. | Xing Tan Peng Gao Yalong Li Pengkai Qi Jingxia Liu Ru Shen Lianghui Wang Nan Huang Kaiqin Xiong Wenjie Tian Qiufen Tu | 2021 | Bioactive Materials2021，6，1： | 0 |
| 5 | How the Antimicrobial Peptides Kill Bacteria:Computational Physics Insights显示文摘In the present article,coarse grained Dissipative Particle Dynamics simulation with implementation of electrostatic interactions is developed in constant pressure and surface tension ensemble to elucidate how the antimicrobial peptidemolecules affect bilayer cellmembrane structure and kill bacteria.We find that peptideswith different chemical-physical properties exhibit differentmembrane obstructing mechanisms.Peptide molecules can destroy vital functions of the affected bacteria by translocating across their membranes via worm-holes,or by associating with membrane lipids to form hydrophilic cores trapped inside the hydrophobic domain of the membranes.In the latter model,the affected membranes are strongly buckled,in accord with very recent experimental observations[G.E.Fantner et al.,Nat.Nanotech.,5(2010),pp.280-285]. | Licui Chen Lianghui Gao Weihai Fang Leonardo Golubovic | 2012 | Communications in Computational Physics2012，11，3： | 0 |
