1Cluster analysis for syndromes of real-world coronary heartdisease with angina pectoris显示文摘Syndromes of coronary heart disease with angina pectoris were analyzed to provide guidance forclinical practice and to improve accuracy of traditional Chinese medicine (TCM) diagnoses and efficacy of TCMtreatment. A total of 860 cases with coronary heart disease with angina pectoris were selected from TCM ClinicalResearch Information Sharing System for TCM clinics and research. Syndromes were automatically extractedwith the cluster method and were analyzed to provide objective evidence for clinical studies. Final syndromeclassifications were recognized and confirmed by clinical experts. Popular syndromes included Qi and blooddeficiency, blood stasis and obstruction collaterals, liver depression and spleen deficiency, and Qi stagnation andblood stasis. Syndromes Qi and blood deficiency and blood stasis and obstruction collaterals accounted for 28.61%of total syndromes, whereas liver depression and spleen deficiency and Qi stagnation and blood stasis accountedfor 26.44%. The main syndrome elements comprised Qi deficiency, blood deficiency, blood stasis, and Qistagnation.Yufeng Zhao Xueyun Yu Xinyu Cao Lin Luo Liyun He Shusong Mao Li Ma Peijing Rong Yuxue Zhao Guozheng Li Baoyan Liu 2018Frontiers of Medicine2018,12,5:28
2Discussion on the relationship between the Yanshanian Movement and cratonic destruction in North China显示文摘The relationship between the Yanshanian Movement, destruction of the North China Craton(NCC), and subduction of the western Pacific plate is crucial to reconstructing the middle-late Mesozoic tectonic evolution of the eastern Asian continent and margin. The Yanshanian Movement was a globally important change in crustal tectonics during the Middle-Late Jurassic.Previous research has systematically studied the formation and evolution of the Yanshanian Movement, focusing on the timing and location of tectonic movements, and the sedimentary and volcanic strata. However, the question of whether the tectonic activity occurred globally, and the characteristics of the Yanshanian Movement remain debated. The main argument is that if a tectonic movement can only be characterized by a regional or local disconformity, and if the tectonic movement occurred in an intracontinental setting, with extensive deformation but with no disconformity despite volcanic eruptions and magmatic intrusions, accompanied by changes in crustal structure and composition, should it be defined as a tectonic event or process? This question requires further analysis. The main aim of this study is to distinguish whether the Yanshanian Movement is a local feature of the eastern Asian continent, or a global tectonic event related to subduction of the Pacific Plate. In this paper, based on previous research, we discuss the spatial and temporal evolution of the Yanshanian Movement, the controlling tectonic mechanisms, and its relationship to the reactivation and destruction of the NCC and the subduction of the western Paleo-Pacific slab.We emphasize that the Yanshanian Movement in the Middle-Late Jurassic is distinct from the lithospheric thinning responsible for Early Cretaceous extension and magmatism related to the destruction of the NCC. The various tectonic stages were constrained by different dynamics and tectonic settings, or by different tectonic events and processes. Therefore, it is possible that the deformation and reactivation of the NCC contributed to its destruction, in addition to lithospheric thinning. Finally, we discuss whether the Yanshanian Movement was associated with the destruction of the NCC.Yu WANG Lixin SUN Liyun ZHOU Yueting XIE 2018Science China Earth Sciences2018,61,5:13

5Early Cretaceous Magma Mingling in Xiaocuo,Southeastern China Continental Margin:Implications for Subduction of Paleo-Pacific Plate显示文摘Magma mingling has been identified within the continental margin of southeastern China.This study focuses on the relationship between mafic and felsic igneous rocks in composite dikes and plutons in this area,and uses this relationship to examine the tectonic and geodynamic implications of the mingling of mafic and felsic magmas.Mafic magmatic enclaves(MMEs) show complex relationships with the hosting Xiaocuo granite in Fujian area,including lenticular to rounded porphyritic microgranular enclaves containing abundant felsic/mafic phenocrysts,elongate mafic enclaves,and back-veining of the felsic host granite into mafic enclaves.LA-ICP-MS zircon U-Pb analyses show crystallization of the granite and dioritic mafic magmatic enclave during ca.132 and 116 Ma.The host granite and MMEs both show zircon growth during repeated thermal events at-210 Ma and 160-180 Ma.Samples from the magma mingling zone generally contain felsic-derived zircons with well-developed growth zoning and aspect ratios of 2-3,and maficderived zircons with no obvious oscillatory zoning and with higher aspect ratios of 5-10.However,these two groups of zircons show no obvious trace element or age differences.The Hf-isotope compositions show that the host granite and MMEs have similar ε_(Hf)(t) values from negative to positive which suggest a mixed source from partial melting of the Meso-Neoproterozoic with involvement of enriched mantlederived magmas or juvenile components.The lithologies,mineral associations,and geochemical characteristics of the mafic and felsic rocks in this study area indicate that both were intruded together,suggesting Early Cretaceous mantle—crustal interactions along the southeastern China continental margin.The Early Cretaceous magma mingling is correlated to subduction of Paleo-Pacific plate.ZHOU Liyun WANG Yu HEI Huixin ZHOU Xiaohui 2016Acta Geologica Sinica(English Edition)2016,90,5:3

10BEM+Born series modeling schemes for wave propagation and their convergence analysis显示文摘This paper formulates two different boundary-element+Born series schemes for wave propagation simulation in multilayered media by incorporating a Born series and boundary integral equations.The first scheme directly decomposes the resulting boundary integral equation matrix into the self-interaction operators associated with each boundary itself and the extrapolation operators expressing cross-interactions between different boundaries in a subregion.For the second scheme,the matrix dimension is firstly reduced to a half by the elimination of the traction field in the equations.The resulting new matrix can also be split into the self-interaction matrices associated each subregion itself and the extrapolation matrices interpreting cross-interactions between different subregions in a whole model.Both the numerical schemes avoid the inversion of the relatively much larger boundary integral equation matrix of a full-waveform BE method and hence save computing time and memory greatly.The two schemes are validated by calculating synthetic seismograms for a homogeneous layered model,compared with the full-waveform BE numerical solution.Numerical experiments indicate that both the BEM+Born series modeling schemes are valid and effective.The tests also confirm that the second modeling scheme has a faster convergence in comparison with the first one.Gengxin Yu Liyun Fu Xizhu Guan 2010Earthquake Science2010,23,2:2

13Incorporation of liquid fillers into silicone foams to enhance the electro-mechanical properties显示文摘Silicone foams with and without liquid fillers(silicone oils of various types and glycerol,respectively)are synthesized and analyzed to be used as dielectric layers in capacitive sensors.A simple fabrication technique involving only four components i.e.Sylgard 184,glycerol,sodium hydroxide and ethanol is used to make these silicone foams after which they are filled with silicone oil or glycerol by soaking the foam in respective liquid.Mechanical and dielectric properties of the foams are examined.The oil reinforces the foam’s dielectric properties,softens the foam and improves its capacitive response,making it a very good dielectric material for fabricating capacitive pressure sensors.Compared to dry silicone foams,foams filled with-and swollen by-chloropropyl-functional silicone oil,show a low Young’smodulus(31 kPa),a high and stable relative dielectric permittivity of around 5,and a high capacitive response of 132%for an appliedpressureof 12 kPa.Thepresence of oil stabilizes the soft foam and ensures that it does not buckle under high pressure.Min Liu Liyun Yu Sindhu Vudayagiri Anne Ladegaard Skov 2020International Journal of Smart and Nano Materials2020,11,1:1
