| 1 | Geochemical and Pb-Sr-Nd isotopic compositions of Indosinian granitoids from the Bikou block,northwest of the Yangtze plate:Constraints on petrogenesis,nature of deep crust and geodynamics显示文摘This paper reports geochemical and Pb-Sr-Nd isotopic compositions of the Indosinian Yangba (215 Ma),Nanyili (225 Ma) and Mopi granitoids from the Bikou block of the northwestern margin of the Yangtze plate. These granitoids are enriched in Al (Al2O3:14.56%―16.48%) and Sr (352 μg/g―1047 μg/g),and depleted in Y (<16 μg/g) and HREE (e.g. Yb<1.61 μg/g),resulting in high Sr/Y (36.3―150) and (La/Yb)N (7.8―36.3) ratios and strongly fractionationed REE patterns. The Indosinian granotoids show initial Sr isotopic ratios (ISr) from 0.70419 to 70752,εNd(t) values from-3.1 to -8.5,and initial Pb isotopic ratios 206Pb/204Pb=17.891-18.250,207Pb/204Pb=15.494-15.575,and 208Pb/204Pb=37.788-38.335. Their geochemi-cal signatures indicate that the granitoids are adakitic. However,they are distinct from some adakites,generated by partial melting of subducted oceanic slab and/or underplated basaltic lower crust,be-cause they have high K (K2O: 1.49%―3.84%) and evolved Nd isotopic compositions,with older Nd iso-topic model ages (TDM=1.06―1.83 Ga). Geochemical and Sr-Nd isotopic compositions suggest that the magmas of the Insoninian adakitic rocks in the Bikou block were derived from partial melting of thick-ened basaltic lower crust. Combined with regional analyses,a lithospheric delamination model after collision between the North China and South China plates can account for the Indosinian adakitic magma generation. On the other hand,based on the Pb-Sr-Nd isotopic probing to the magma sources of the adakitic rocks,it is suggested that there is an unexposed continent-type basement under the exposed Bikou Group volcanic rocks. This can constrain on the Bikou Group volcanic rocks not to be MORB-or OIB-type. | ZHANG HongFei XIAO Long ZHANG Li YUAN HongLin JIN LanLan | 2007 | Science China Earth Sciences2007，50，7： | 38 |
| 2 | Performance Evaluation of Two-Vector-Based Model Predictive Current Control of PMSM Drives显示文摘Conventional model predictive current control(MPCC)applies only one vector during one control period,which produces large torque and flux ripples and high current harmonics in permanent magnet synchronous motor(PMSM)drives.Recently MPCC with duty cycle control has been proposed to improve the steady state performance by applying one non-zero vector and one null vector during one control period.However,the prior method requires lots of calculations and predictions to find the optimal voltage vectors and calculate their respective duration.Different from prior enumeration-based MPCC,this paper proposes an efficient two-vector MPCC by applying two arbitrary voltage vectors during one control period.The reference voltage vector is firstly calculated based on the principle of deadbeat current control.Two optimal vectors and their duration are then obtained in a very efficient way,which does not require the calculation of current slopes in prior MPCC methods.The proposed method is compared to the state-of-the-art predictive control methods,including conventional MPCC,MPCC with duty cycle control,deadbeat control with space vector modulation(SVM)and modulated model predictive control(M2PC).Both simulation and experimental results prove that the proposed method achieves better steady state performance than conventional MPCC with or without duty cycle and the dynamic response is not degraded.Under the condition of insufficient dc bus voltage,the proposed method outperforms deadbeat control and M2PC by presenting even higher speed range and less torque ripples. | Yongchang Zhang Lanlan Huang Donglin Xu Jiali Liu Jialin Jin | 2018 | Chinese Journal of Electrical Engineering2018，4，2： | 9 |
| 3 | Three-dimensional printing for heart diseases: clinical application review显示文摘Heart diseases remain the top threat to human health,and the treatment of heart diseases changes with each passing day.Convincing evidence shows that three-dimensional(3D)printing allows for a more precise understanding of the complex anatomy associated with various heart diseases.In addition,3D-printed models of cardiac diseases may serve as effective educational tools and for hands-on simulation of surgical interventions.We introduce examples of the clinical applications of different types of 3D printing based on specific cases and clinical application scenarios of 3D printing in treating heart diseases.We also discuss the limitations and clinically unmet needs of 3D printing in this context. | Yanyan Ma Peng Ding Lanlan Li Yang Liu Ping Jin Jiayou Tang Jian Yang | 2021 | Bio-Design and Manufacturing2021，4，3： | 3 |
| 4 | Altered heartbeat perception sensitivity associated with brain structural alterations in generalised anxiety disorder显示文摘Background Palpitation is a common complaint in generalised anxiety disorder(GAD).Brain imaging studies have Investigated the neural mechanism of heartbeat perception in healthy volunteers.This study explored the neuroanatomical differences of altered heartbeat perception in patients with GAD using structural MRI.Aims Based on the strong somatic-interoceptive symptoms in GAD,we explored the regional structural brain abnormalities involved in heartbeat perception in patients with GAD.Methods This study was applied to the a priori regions using neuroanatomical theories of heartbeat perception,including the insula,anterior cingulate cortex,supplementary motor area and prefrontal cortex.A total of 19 patients with GAD and 19 healthy control subjects were enrolled.We used the FMRIB Software Library voxel-based morphometry software for estimating the grey matter volume of these regions of interest and analysed the correlation between heartbeat perception sensitivity and the volume of abnormal grey matter.Results Patients with GAD showed a significantly decreased volume of grey matter in their left medial prefrontal cortex,right orbital frontal cortex and anterior cingulate cortex.The grey matter volume of the left medial prefrontal cortex negatively correlated with heartbeat perception sensitivity in patients with GAD.Conclusions It should be the first study that shows heartbeat perception is associated with brain structure in GAD.Our findings suggest that the frontal region may play an important role in aberrant heartbeat perception processing in patients with GAD,and this may be an underlying mechanism resulting in the abnormal cardiovascular complaints in GAD.This is hypothesised as a'top-down'deficiency,especially in the medial prefrontal cortex.This will provide the foundation for a more targeted region for neuromodulation intervention in the future. | Hui Li Bin Zhang Qiang Hu Lanlan Zhang Yi Jin Jijun Wang Huiru Cui Jiaoyan Pang Chunbo Li | 2020 | General Psychiatry2020，33，1： | 2 |
| 5 | Bioinspired membranes for multi-phase liquid and molecule separation显示文摘Water pollution is a serious problem around the world. It causes the lack of clean drinking water and brings risks to human health.Membrane technology has become a competitive candidate to treat the contaminated wastewater due to its high separation efficiency and low energy consumption. In this review, we introduce the recent development of several kinds of bioinspired separation membranes, involving the membrane design and applications. We emphasize the multi-phase liquid separation membranes inspired from nature with special wettability applied for oil/water separation, organic liquids mixture separation, and emulsion separation. After separating multi-phase liquids using these membranes, small molecule pollutants still exist in singlephase liquid. Therefore, we also expand the scope to small molecule-scale separation membranes, such as the nacre-like graphene oxide separation membrane and other nanofiltration membranes. Summary and outlook concerning the future development of separation membranes are also introduced briefly. | Jingchong Liu Zhimin Cui Lanlan Hou Dianming Li Yuan Gao Li Shuai Jing Liu Jian Jin Nü Wang Yong Zhao | 2019 | Science China Chemistry2019，62，1： | 2 |
| 6 | A non‐equal gap distance dielectric barrier discharge:Between cone‐shape and cylinder‐shape electrodes显示文摘A non‐equal gap distance dielectric barrier discharge(DBD)between cone‐shape and a cylinder‐shaped electrodes is reported.The DBD is driven by a nanosecond voltage pulse.When the pulse frequency is 500 Hz or lower,ladder‐shape plasma with multiple plasma layers is generated within the gap,with a distance increasing from 1 to 7 mm.According to high‐speed photographs of the plasma captured by an intensified charge‐coupled camera detector camera,the ladder‐shaped plasma is formed owing to propa-gation of ring‐shaped plasma from the region of the short‐gap distance to the region of long‐gap distance with regular variations in its propagation speed.The propagation speed drops to zero and lasts for about 20-30 ns at the region of each plasma layer,which results in bright plasma layers.The electric field of the plasma layer at the region of the different gap distance is evaluated according to the optical emission intensity ratio R_(391)/_(394)of N_(2)^(+)at 391 nm and N_(2) at 394 nm.The obtained electric field drops from 8.1 to 6.4 kV/mm when the plasma is propagated from regions of gap distance of 2-5 mm.When the pulse frequency is increased to 1 kHz or higher,the discharge changes into a filamentary mode and the multiple‐layer plasma disappears. | Shaohui Jin Zhiyu Li Yubin Xian Lanlan Nie Xinpei Lu | 2022 | High Voltage2022，7，1： | 2 |
