1Design and experiment on intelligent fuzzy monitoring system for corn planters显示文摘When sowing summer corn without tillage,it is necessary to ensure that the furrow opener is free from straw congestion and that the spacing of the sowing can be adjusted according to the breeds of corn and the preset seeding rate per acre.On the basis of the structural features of newly developed no-tillage corn fertilizers,an intelligent fuzzy monitoring system for corn planters was developed in this study.The system facilitates automatic control of the spacing adjustment and the status monitor for the fertilizer tank,seed tank,and seeding orifice.According to the preset number of rows,line spacing,number of plants per acre,and seed germination rate,the control rate can be calculated through designing in surveillance software.The control rate is output to the fuzzy controller through the digital output module of the CAN bus.Fuzzy control is applied to the DC motor for stepless adjustment of the spacing.A system for video surveillance of the working status of a planter is developed for displaying a real-time video image of the planter operation and achieving an anti-congestion status monitoring of a no-tillage planting operation in a dusty environment.Through field trials,the detection accuracy was 91.4%.The seed-clogging fault-alarm accuracy was 96.0%.The entire system remained stable and reliable.Du Ruicheng Gong Bingcai Liu Ningning Wang Chenchen Yang Zidong Ma Mingjian 2013International Journal of Agricultural and Biological Engineering2013,6,3:16
2Features and origin time of Mesozoic strike-slip structures in the Yilan-Yitong Fault Zone显示文摘The NE-striking Yilan-Yitong Fault Zone(YYFZ) with a length of ca. 900 km is an important major fault zone in northeastern China. Its origin has been a controversial issue for a long time. Detailed field investigation and comprehensive analyses show that strike-slip faults or ductile shear belts exist as the origination structures on the both shoulders of the Cretaceous-Paleogene grabens. These strike-slip structures are dominated by brittle transcurrent faults, and appear as ductile shear belts only in the Weiyuanpu-Yehe and Shulan parts in the south and middle of the fault zone, respectively. The shear belts strike NE-SW and show steep mylonitic foliation and gentle mineral elongation lineation. Outcrop structures, microstructures and quartz c-axis fabrics demonstrate a sinistral shear sense with minor reverse component for the ductile shear belts. The microstructures suggest deformation temperatures of 400–450°C for the Weiyuanpu-Yehe shear belts and 350–400°C for the Shulan shear belt. A series of zircon U-Pb dating results for deformed and undeformed plutons or dikes in the shear belts constrain the strike-slip motion to the time between 160 and 126 Ma. It is further inferred from ages of main geological events in this region that the fault zone originated in the earliest Early Cretaceous. It is suggested therefore that the southern and middle parts of the Tan-Lu Fault Zone, which originated in Middle Triassic, propagated into northeastern China along the sinistral YYFZ under the earliest Early Cretaceous regional compression that is referred to as the Yanshan B event. The earliest Early Cretaceous initiation of the YYFZ results from both the high-speed oblique subduction of the Izanagi Plate and the final closure of the Mongol-Okhotsk Ocean, but the Izanagi Plate subduction played a major dynamic role in the fault zone origin.GU ChengChuan ZHU Guang ZHAI MingJian LIN ShaoZe SONG LiHong LIU Bei 2016Science China(Information Sciences)2016,59,12:10
3Co-Seismic Surface Rupture and Recurrence Interval of Large Earthquakes along Damaoyaba-Litang Segment of the Litang Fault on the Eastern Margin of the Tibetan Plateau in China显示文摘The Litang fault is a left-lateral secondary shear zone in the Sichuan-Yunnan active block that accommodates the tectonic deformation associated with the eastward extrusion of the upper crust of the Tibetan Plateau. Based on 1 : 50 000 geological mapping of active faults, the Litang fault consists of three geometric segments, the Cuopuhu, Damaoyaba, and Litang segments, in the west of Litang, which are divided by the of Haizi Mountain uplift and the wide-angle bending and branching of the fault near Jinchanggou. This study also identifies the surface rupture of the A.D. 1890 earthquake, which is distributed intermittently along the ~28 km long Damaoyaba segments and ~25 km long Litang segments. The maximum horizontal displacement is 4.1 m along Damaoyaba segments, and 4 m along Litang segments. The rupture involves typical left-lateral shear movement. The two ruptures are divided by discontinuous segments or gaps that are ~18 km long;thus, the total surface rupture is approximately 71 km long. The estimated moment magnitude was M_(w)7.3±0.1. A comprehensive analysis of data obtained from 5 trenches excavated along the Damaoyaba and Litang segments and the trench data by Xu et al.(2005) identifies age constraints of the 4 most recent paleoseimic events occurred B.C. 1468±54–1340±25, B.C. 52±25–A.D. 76±47, A.D. 1115±90, and A.D. 1890, respectively. The recurrence intervals are 1 415±80, 1 104±104, and 775±90 a, which are consistent with quasi-periodic earthquake recurrence behavior. The average recurrence interval is 1 098±112 a.Shiyuan Wang Rongjun Zhou Mingjian Liang Shao Liu Nina Liu Jianyu Long 2021Journal of Earth Science2021,32,5:5
4Optimal capacity planning of combined renewable energy source-pumped storage and seawater desalination systems显示文摘As water scarcity is becoming a growing threat to human development, finding effective solutions has become an urgent need. To make better use of water resources, seawater desalination and storage systems using renewable energy sources(RES) are designed and implemented around the world. In this paper, an optimal capacity planning method for RES-pumped storage-seawater desalination(RES-PS-D) system is introduced. The configuration of the RES-PS-D system is clarified first, after which a cost-benefit analysis is performed using all cost and benefit components. A function for determining maximum economic benefits of the RES-PS-D system is then established, and the constraints are proposed based on various limitations. The mixed-integer linear programming algorithm is applied to solve the optimal function. A case study is introduced to validate the feasibility and effectiveness of the method. The conclusion shows that the strategy is suitable for solving the configuration optimization problem, and finally both merits and defects of the method are discussed.Boyu Liu Bowen Zhou Dongsheng Yang Zhile Yang Mingjian Cui 2019Global Energy Interconnection2019,2,4:4

6Light-triggered nitric oxide release and structure transformation of peptide for enhanced intratumoral retention and sensitized photodynamic therapy显示文摘Tumor-targeted delivery of nanomedicine is of great importance to improve therapeutic efficacy of cancer and minimize systemic side effects.Unfortunately,nowadays the targeting efficiency of nanomedicine toward tumor is still quite limited and far from clinical requirements.In this work,we develop an innovative peptide-based nanoparticle to realize light-triggered nitric oxide(NO)release and structural transformation for enhanced intratumoral retention and simultaneously sensitizing photodynamic therapy(PDT).The designed nanoparticle is self-assembled from a chimeric peptide monomer,TPP-RRRKLVFFK-Ce6,which contains a photosensitive moiety(chlorin e6,Ce6),aβ-sheet-forming peptide domain(Lys-Leu-Val-Phe-Phe,KLVFF),an oligoarginine domain(RRR)as NO donor and a triphenylphosphonium(TPP)moiety for targeting mitochondria.When irradiated by light,the constructed nanoparticles undergo rapid structural transformation from nanosphere to nanorod,enabling to achieve a significantly higher intratumoral accumulation by 3.26 times compared to that without light irradiation.More importantly,the conversion of generated NO and reactive oxygen species(ROS)in a light-responsive way to peroxynitrite anions(ONOO)with higher cytotoxicity enables NO to sensitize PDT in cancer treatment.Both in vitro and in vivo studies demonstrate that NO sensitized PDT based on the well-designed transformable nanoparticles enables to eradicate tumors efficiently.The light-triggered transformable nanoplatform developed in this work provides a new strategy for enhanced intratumoral retention and improved therapeutic outcome.Lingdong Jiang Danyang Chen Zhaokui Jin Chao Xia Qingqing Xu Mingjian Fan Yunlu Dai Jia Liu Yuanpei Li Qianjun He 2022Bioactive Materials2022,7,6:3
7Light emission properties of sapphire under shock loading in the stress range of 40-120 GPa显示文摘The measurement of emissions from the window material of sapphire was performed through multi-wavelength pyrometer and spontaneous spectroscopic techniques in the pressure range of 40-120 GPa.The results showed that the spectral distribution with wavelength clearly fit well with the grey-body spectrum.We have analyzed the emissions and discovered they mostly came from the shear banding,which is a typical thermal radiation.The radiance intensity changing linearly with time revealed it was a volume effect.All of the data from pyrometer can be explained by the model of Boslough's study,especially for pressures over megabar.The color temperature of shocked sapphire changing with increased stress disagrees with the computed melt curve which is likely explained by the different phase structures of sapphire.ZHANG NingChao LIU FuSheng PENG XiaoJuan ZHANG MingJian CHEN JunXiang 2013Science China Chemistry2013,56,3:2
8An infrared thermographic analysis of the sensitization acupoints of women with primary dysmenorrhea显示文摘OBJECTIVE:To explore the sensitization acupoints of women with primary dysmenorrhea(PD)by comparing infrared radiation temperatures between acupoints and non-acupoints.METHODS:We tested 10 acupoints of every woman with PD and healthy subjects on premenstrual,menstrual,and postmenstrual days using an infrared imaging device.The primary outcome was the absolute value of body surface temperature difference(AVTD)between the left and right sides of the same testing point.RESULTS:A total of 58 PD patients and 57 healthy volunteers completed the test from May 2016 to May 2017.Compared with the healthy group,we observed a significant reduction and increase in the AVTD in Taichong(LR3)and Sanyinjiao(SP6),respectively,during menstrual days in the PD group(P=0.01;P=0.04);while during postmenstrual days,all AVTDs of Shuiquan(KI5),Diji(SP8),and Xuehai(SP10)were diminished in the PD group(P=0.01;P=0.03;P=0.01,respectively).No significant differences in AVTD were detected at any other points or testing times.CONCLUSIONS:Compared with the healthy group,the AVTDs of Taichong(LR3),Sanyinjiao(SP6),Shuiquan(KI5),Diji(SP8),and Xuehai(SP10)at menstruationrelevant points of PD patients were sensitized,providing a reference for the selection of acupoints in the treatment of PD.FAN Xisheng DU Xiaoyi PAN Lijia SONG Xiaodan LIU Jun ZHANG Juncha CHEN Hao GAO Yayu ZHANG Mingjian SHI Xuliang SHE Yanfen 2022Journal of Traditional Chinese Medicine2022,42,5:2
9Chemical sensors based on π-conjugated organic molecules and gold nanoparticles显示文摘Scientists have developed techniques for synthesizing and characterizing many new materials including conjugated small molecules, polymers and gold particles protected by conjugated organic chromophores for testing specific sensing properties in the past decade. Still, the design and synthesis or supermolecular systems fabrication of novel materials with controlled sensing properties is a significant and ongoing challenge within nanoscience and nanotechnology. Recently, our group has successfully constructed a series of chemosensors using small organic molecules, conjugated polymers and gold nanoparticles for real-time detection of specific analytes. The chemosensors show high selectivity and sensitivity in the detection of cations and biologic analytes and thus are potentially promising for applications in sensing assay system. In this review, recent sutdies on the design, synthesis and photo-physical properties of novel materials and construct of chemosensors are summarized with an emphasis on the development in our groups in recent years.YUAN MingJian LI YongJun LIU HuiBiao LI YuLiang 2009Science China Chemistry2009,52,6:2

18CoS_(2)nanowires supported graphdiyne for highly efficient hydrogen evolution reaction显示文摘Transition metal sulfides are an important category for hydrogen evolution reaction(HER).However,only few edge unsaturated sulfurs functionalize as catalytic sites,which has dramatically limited the catalytic activity and stability.In this work,planar unsaturated sulfurs in(211)plane of the CoS_(2)nanowires have been successfully activated through constructing Graphdiyne-CoS_(2)heterojunction nanocomposites.The corresponding electrons transfer energy barriers for these planar unsaturated sulfurs have been significantly diminished,which are induced by the synergetic effects of the sp~1 hybridized carbons and unsaturated planar sulfurs.In addition,DFT simulations reveal the synergetic effects of the sp~1 hybridized carbons and unsaturated planar sulfurs can promote electron transfer kinetics of the key step,VolmerHeyrovsky step,of the reaction.As expected,the Graphdiyne-CoS_(2)heterojunction nanocomposites exhibit superior HER catalytic performance with low overpotential of 97 mV at 10 mA cm^(-2),and the Tafel slope of 56 mV dec^(-1).Furthermore,the heterojunction shows outstanding stability as well due to the pr tection of the Graphdiyne(GDY).The approach thus paves the way for the further efficient transition metal disulfides catalyst manufactures.Wangjing Xie Kang Liu Guodong Shi Xinliang Fu Xiaojie Chen Zixiong Fan Min Liu Mingjian Yuan Mei Wang 2021Journal of Energy Chemistry2021,30,9:1

20Deep Convective Clouds over the Northern Pacific and Their Relationship with Oceanic Cyclones显示文摘Based on combined Cloud Sat/CALIPSO detections, the seasonal occurrence of deep convective clouds(DCCs) over the midlatitude North Pacific(NP) and cyclonic activity in winter were compared. In winter, DCCs are more frequent over the central NP, from approximately 30°N to 45°N, than over other regions. The high frequencies are roughly equal to those occurring in this region in summer. Most of these DCCs have cloud tops above a 12 km altitude, and the highest top is approximately 15 km. These wintertime marine DCCs commonly occur during surface circulation conditions of low pressure, high temperature, strong meridional wind, and high relative humidity. Further, the maximum probability of DCCs,according to the high correlation coefficient, was found in the region 10°–20° east and 5°–10° south of the center of the cyclones. The potential relationship between DCCs and cyclones regarding their relative locations and circulation conditions was also identified by a case study. Deep clouds were generated in the warm conveyor belt by strong updrafts from baroclinic flows. The updrafts intensified when latent heat was released during the adjustment of the cyclone circulation current. This indicates that the dynamics of cyclones are the primary energy source for DCCs over the NP in winter.YI Mingjian FU Yunfei LIU Peng ZHENG Zhixia 2015Advances in Atmospheric Sciences2015,32,6:1
