1Renewed profile of the Mesozoic magmatism in Korean Peninsula: Regional correlation and broader implication for cratonic destruction in the North China Craton显示文摘Widespread Mesozoic magmatism occurs in the Korean Peninsula(KP). The status quo is poles apart between the northern and southern parts in characterizing its distribution and nature, with the nearly absence of any related information in North Korea. We have the opportunity to have conducted geological investigations in North Korea and South Korea during the past ten years through international cooperation programs. This led to the revelation of a number of granitoids and related volcanic rocks and thus facilitates the comparison with those in East China and Japan. Mesozoic granitoids in the KP can be divisible into three age groups: the Triassic group with a peak age of ~220 Ma, the Jurassic one of ~190–170 Ma and the late Early Cretaceous one of ~110 Ma. The Triassic intrusions include syenite, calc-alkaline to alkaline granite and minor kimberlite in the Pyeongnam Basin of North Korea. They have been considered to form in post-orogenic settings related to the Central Asian Orogenic Belt(CAOB) or the Dabie-Sulu Orogenic Belt(DSOB). The Jurassic granitoids constitute extensive occurrence in the KP and are termed as the Daebo-period magmatism. They correlate well with coeval counterparts in NE China encompassing the northeastern part of the North China Craton(NCC) and the eastern segment of the CAOB. They commonly consist of biotite or two-mica granites and granodiorites, with some containing small dark diorite enclaves. On one hand, Early Jurassic to early Middle Jurassic magmatic rocks are rare in most areas of the NCC, whilst Middle-Late Jurassic ones are not developed in the KP. On the other hand, both NCC and KP host abundant Cretaceous granites. However, the present data revealed contrasting age peaks, with ~130–125 Ma in the NCC and ~110–105 Ma in the KP. Cretaceous granites in the KP comprise the dominant biotite granites and a few amphibole granites. The former exhibit mildly fractionated REE patterns and zircon εHf(t) values from ?15 to ?25, whereas the latter feature strongly fractionated REE patterns and zircon εHf(t) values from ?10 to ?1. Both granites contain inherited zircons of ~1.8–1.9 or ~2.5 Ga. These geochemical characters testify to their derivation from re-melting distinct protoliths in ancient basement. Another Cretaceous magmatic sub-event has been entitled as the Gyeongsang volcanism, which is composed of bimodal calc-alkaline volcanic rocks of 94–55 Ma and granitic-hypabyssal granitic bodies of 72–70 Ma. Synthesizing the Mesozoic magmatic rocks across the KP, NCC and Japan can lead to the following highlights:(1) All Triassic granites in the NCC, KP and Japan have similar characteristics in petrology, chronology and geochemistry. Therefore, the NCC, KP and Japan tend to share the same tectonic setting during the Triassic, seemingly within the context of Indosinian orogensis.(2) Jurassic to earliest Cretaceous magmatic rocks in the NCC seem to define two episodes: episode A from 175 to 157 Ma and episode B from 157 to 135 Ma. Jurassic magmatic rocks in the KP span in age mainly from 190 to 170 Ma, whereas 160–135 Ma ones are rare. With the exception of ~197 Ma Funatsu granite, Jurassic magmatic rocks are absent in Japan.(3) Cretaceous granites in the KP have a peak age of ~110, ~20 Ma younger than those in the NCC, while Japan is exempt from ~130–100 Ma granites.(4) The spatial-temporal distribution and migratory characteristics of theJurassic-Cretaceous magmatic rocks in Japan, KP, and NE China-North China indicate that the subduction of the Paleo-Pacific plate might not be operative before Late Cretaceous(~130–120 Ma).(5) Late Cretaceous magmatic rocks(~90–60 Ma) occur in the southwestern corner of the KP and also in Japan, coinciding with the metamorphic age of ~90–70 Ma in the Sanbagawa metamorphic belt of Japan. The magmatic-metamorphic rock associations and their spatial distribution demonstrate the affinities of sequentially subduction zone, island arc and back-arc basin from Japan to Korea, arguing for the Pacific plate subduction during Late Cretaceous.(6) This study raises another possibility that the Mesozoic cratonic destruction in the NCC, which mainly occurred during ~150–120 Ma, might not only be due to the subduction of the Paleo-Pacific Plate, but also owe much to the intraplate geodynamic forces triggered by other adjacent continental plates like the Eurasian and Indian plates.ZHAI MingGuo ZHANG YanBin ZHANG XiaoHui WU Fu Yuan PENG Peng LI Qiu Li HOU QuanLin LI TieSheng ZHAO Lei 2016Science China(Information Sciences)2016,59,12:16
2Classification of Tibetan lakes based on variations in seasonal lake water temperature显示文摘Widespread lakes on the Tibetan Plateau(TP)are valuable archives for investigating climate and environment changes, which could provide essential information on the mechanisms of past climate changes on the TP and their interaction with the global climate systems.However, there is a lack of in-depth investigation of modern limnological processes in the Tibetan lakes, which hampers the understanding of paleolimnological records and lake ecosystem succession. In this study, we performed continuous temperature monitoring at two lakes, Bangong Co, a freshwater lake in the western TP, and Dagze Co, a brackish lake in the central TP, in order to characterize the patterns of seasonal temperature variability, stratification,and mixing. Temperature data for an entire hydrological year demonstrate that Bangong Co is a dimictic lake and that Dagze Co is a meromictic lake. The higher salinity in the deep water at Dagze Co prevents the lake from overturning completely, and this finding is supported by simulations using a physical limnological model Lake Analyzer. Continuous lake water temperature monitoring provides fundamental data for classifying Tibetan lakes, as well as the hydrological basis for understanding their paleolimnological records and ecosystem succession.Mingda Wang Juzhi Hou Yanbin Lei 2014Chinese Science Bulletin2014,59,34:10
3Climate variability recorded by n-alkanes of paleolake sediment in Qaidam Basin on the northeast Tibetan Plateau in late MIS3显示文摘Here we combine n-alkanes preserved in a shell bar section from Qarhan paleolake, Qaidam Basin with the other sedimentary proxies to elucidate the lake evolution process during the period 39.7 to 17.5 14C ka BP (calibrated age ranges from 43.5 to 22.4 cal. ka BP). In different stages, the n-alkane homologues exhibited different distribution modes indicative of variations in the surrounding vegetation and the hydrologic condition of the lake. The n-alkanes proxies (CPIh, ACLh, Paq) have the same trends as the summer solar insolation variation, implying that the summer insolation is the most important climatic factor driving the environmental changes and also indirectly controls lake evolution on the Tibetan Plateau. CPIh and ACLh as well as the total pollen concentration appear to show a trend comparable with methane concentration record from the GRIP ice core that reflected the Dansgaard-Oeschger events. This demonstrates that the paleoclimate variations in Qarhan area generally agree with global climate change and show rapid oscillations in late MIS3. These findings provide the latest molecular fossil evidence from paleolake sediments to confirm that lake evolution on Tibetan Plateau in late MIS3 was closely associated with enhanced summer insolation.PU Yang ZHANG HuCai LEI GuoLiang CHANG FengQin YANG MingSheng ZHANG WenXiang LEI YanBin YANG LunQing PANG YouZhi 2010Science China Earth Sciences2010,53,6:8
4Microphysical Characteristics of Precipitation during Pre-monsoon,Monsoon, and Post-monsoon Periods over the South China Sea显示文摘Raindrop size distribution (RSD) characteristics over the South China Sea (SCS) are examined with onboard Parsivel disdrometer measurements collected during marine surveys from 2012 to 2016. The observed rainfall is divided into premonsoon, monsoon, and post-monsoon periods based on the different large-scale circumstances. In addition to disdrometer data, sounding observation, FY-2E satellite, SPRINTARS (Spectral Radiation-Transport Model for Aerosol Species), and NCEP reanalysis datasets are used to illustrate the dynamical and microphysical characteristics associated with the rainfall in different periods. Significant variations have been observed in respect of raindrops among the three periods. Intercomparison reveals that small drops (D < 1 mm) are prevalent during pre-monsoon precipitation, whereas medium drops (1?3 mm) are predominant in monsoon precipitation. Overall, the post-monsoon precipitation is characterized by the least concentration of raindrops among the three periods. But, several large raindrops could also occur due to severe convective precipitation events in this period. Classification of the precipitation into stratiform and convective regimes shows that the lg(Nw) value of convective rainfall is the largest (smallest) in the pre-monsoon (post-monsoon) period, whereas the Dm value is the smallest (largest) in the pre-monsoon (post-monsoon) period. An inversion relationship between the coefficient A and the exponential b of the Z?R relationships for precipitation during the three periods is found. Empirical relations between Dm and the radar reflectivity factors at Ku and Ka bands are also derived to improve the rainfall retrieval algorithms over the SCS. Furthermore, the possible causative mechanisms for the significant RSD variability in different periods are also discussed with respect to warm and cold rain processes, raindrop evaporation, convective activities, and other meteorological factors.Qingwei ZENG Yun ZHANG Hengchi LEI Yanqiong XIE Taichang GAO Lifeng ZHANG Chunming WANG Yanbin HUANG 2019Advances in Atmospheric Sciences2019,36,10:7
5A hybrid quantum-based PIO algorithm for global numerical optimization显示文摘A novel hybrid quantum-based pigeon-inspired optimization(PIO) algorithm for global numerical optimization is proposed to perceive deceptiveness and preserve diversity. In the proposed algorithm,the current best solution is regarded as a linear superposition of two probabilistic states, namely positive and deceptive. Through a quantum rotation gate, the positive probability is either enhanced or reset to balance exploration and exploitation. Simulation results reveal that the hybrid quantum-based PIO algorithm demonstrates an outstanding performance in global optimization owing to preserving diversity in the early evolution. As a result, the stability of the algorithm is enhanced so that the precision of optimization is improved statistically. The proposed algorithm is demonstrated to be effective for solving multimodal and non-convex problems in higher dimension with a smaller population size.Boyi CHEN Hao LEI Haidong SHEN Yanbin LIU Yuping LU 2019Science China(Information Sciences)2019,62,7:7
6Twistor-based synchronous sliding mode control of spacecraft attitude and position显示文摘A synchronous control of relative attitude and position is required in separated ultraquiet spacecraft, such as drag-free, disturbance-free, and distributed spacecraft. Thus, a twistorbased synchronous sliding mode control is investigated in this paper to solve the control problem of relative attitude and position among separated spacecraft modules. The twistor-based control design and the stability proof are implemented using the Modified Rodrigues Parameter(MRP).To evaluate the effectiveness of the proposed control method, this paper presents a case study of separated spacecraft flying control considering the mass uncertainty and external disturbances. In addition, a simulation study of the Proportional-Derivative(PD) control is also presented for comparison. The results indicate that the twistor-based sliding mode controller can ensure global asymptotic stability. The states converge fast with ultra-precision and ultra-stability in both the attitude and position. Moreover, the proposed twistor-based sliding mode control system is robust to the mass uncertainty and external disturbances.Qing LI Lei LIU Yifan DENG Shuo TANG Yanbin ZHAO 2018Chinese Journal of Aeronautics2018,31,5:5
7Microstructure,tensile properties and thermal stability of AlMgSiScZr alloy printed by laser powder bed fusion显示文摘The new generation of Sc and Zr modified Al alloys has been attracted wide concerns in aerospace industry,owing to the excellent mechanical performances and superior thermal stability than other normal Al alloys.By microalloying with Sc and Zr,the Al3(Sc,Zr)particle forms as the grain refiner during the solidification,which is extremely beneficial for the laser powder bed fusion(LPBF)processed Al alloys.In this study,a new type Al-14.1 Mg-0.47 Si-0.31 Sc-0.17 Zr alloy was additively manufactured by LPBF,and the microstructure,tensile properties and thermal stability were studied in detail.By using a single melt-67°scanning strategy,the LPBF-processed specimen with a relative density of 99.4%and tensile strength of 487.7 MPa was obtained at 160 W-200 mm/s.And this AlMgSiScZr alloy can still exhibit an excellent tensile strength of 393.9 MPa at a moderate temperature of 473 K.After the aging treatment,the tensile properties further increased due to the precipitate hardening of Mg2Si and Al3(Sc,Zr),and the maximum value(580 MPa)was reached at an aging time of 10 h.The average crystal size was almost unchanged after aging treated at 325℃and 24 h,indicating this AlMgSiScZr alloy has an improved thermal stability.The AlMgSiScZr alloy is recommended to substitute some particular titanium alloys in aerospace field afterwards.Jiang Bi Zhenglong Lei Yanbin Chen Xi Chen Ze Tian Nannan Lu Xikun Qin Jingwei Liang 2021Journal of Materials Science & Technology2021,,10:4
8Performance limitations in trajectory tracking control for air-breathing hypersonic vehicles显示文摘An integrated approach that considers the performance limitations of tracking control systems for air-breathing hypersonic vehicles is proposed. First, a set of ascent trajectories is obtained as candidates for tracking control through a trajectory design method that considers the available acceleration. Second, the basic theory of performance limitations, which is adopted to calculate the limits on control performance through the trajectory, is integrated. The openloop dynamics of air-breathing hypersonic vehicles is responsible for these limits on the control system. Comprehensive specifications on stability, tracking accuracy, and robustness are derived, and the flight envelope with constraints and control specifications is identified. Simulation results suggest that trajectory design should consider restrictions on control performance to obtain reliable solutions.Boyi CHEN Yanbin LIU Haidong SHEN Hao LEI Yuping LU 2019Chinese Journal of Aeronautics2019,32,1:4
9Stable Lithium-Carbon Composite Enabled by Dual-Salt Additives显示文摘Lithium metal is regarded as the ultimate negative electrode material for secondary batteries due to its high energy density.However,it suffers from poor cycling stability because of its high reactivity with liquid electrolytes.Therefore,continuous efforts have been put into improving the cycling Coulombic efficiency(CE)to extend the lifespan of the lithium metal negative electrode.Herein,we report that using dual-salt additives of LiPF_(6) and LiNO_(3) in an ether solvent-based electrolyte can significantly improve the cycling stability and rate capability of a Li-carbon(Li-CNT)composite.As a result,an average cycling CE as high as 99.30% was obtained for the Li-CNT at a current density of 2.5 mA cm^(-2) and an negative electrode to positive electrode capacity(N/P)ratio of 2.The cycling stability and rate capability enhancement of the Li-CNT negative electrode could be attributed to the formation of a better solid electrolyte interphase layer that contains both inorganic components and organic polyether.The former component mainly originates from the decomposition of the LiNO_(3) additive,while the latter comes from the LiPF_(6)-induced ring-opening polymerization of the ether solvent.This novel surface chemistry significantly improves the CE of Li negative electrode,revealing its importance for the practical application of lithium metal batteries.Lei Zheng Feng Guo Tuo Kang Yingzhu Fan Wei Gu Yayun Mao Ya Liu Rong Huang Zhiyun Li Yanbin Shen Wei Lu Liwei Chen 2021Nano-Micro Letters2021,13,7:3

11A portable viable Salmonella detection device based on microfluidic chip and recombinase aided amplification显示文摘creening of foodborne pathogens is important to prevent contaminated foods from their supply chains.n this study, a portable detection device was developed for rapid, sensitive and simple detection of viable almonella using a finger-actuated microfluidic chip and an improved recombinase aided amplification (RAA) assay. Improved propidium monoazide(PMAxx) was combined with RAA to enable this device to distinguish viable bacteria from dead ones. The modification of PMAxx into dead bacteria, the magnetic xtraction of nucleic acids from viable bacteria and the RAA detection of extracted nucleic acids were performed using the microfluidic chip on its supporting device by finger press-release operations. The fluorescent signal resulting from RAA amplification of the nucleic acids was collected using a USB camera nd analyzed using a self-developed smartphone App to quantitatively determine the bacterial concenration. This device could detect Salmonella typhimurium in spiked chicken meats from 1.3 × 10^(2) CFU/m L o 1.3 × 10^(7) CFU/m L in 2 h with a lower detection limit of 130 CFU/m L, and has shown its potential for on-site detection of foodborne pathogens.Wuzhen Qi Siyuan Wang Lei Wang Xinge Xi Shangyi Wu Yanbin Li Ming Liao Jianhan Lin 2023Chinese Chemical Letters2023,34,2:2
12Polydopamine-modified collagen sponge scaffold as a novel dermal regeneration template with sustained release of platelet-rich plasma to accelerate skin repair:A one-step strategy显示文摘Although employed to release growth factors(GFs)for regenerative medicine,platelet-rich plasma(PRP)has been hindered by issues like burst effect.Based on collagen sponge scaffolds(CSSs)modified with polydopamine(pDA),a novel dermal regeneration template(DRT)was designed.However,whether it could efficiently deliver PRP and even foster wound healing remained unclear.In this work,after PRP was prepared and pDA-modified CSSs(pDA-CSSs)were fabricated,microscopic observation,GFs release assay and in-vitro biological evaluations of pDA-CSSs with PRP(pDA-CSS@PRP)were performed,followed by BALA-C/nu mice full-thickness skin defects implanted with pDA-CSS@PRP covered by grafted skins(termed as a One-step strategy).As a result,scanning electron microscope demonstrated more immobilized platelets on pDA-CSS′surface with GFs’controlled release via enzyme-linked immunosorbent assay,compared with CSSs.In line with enhanced in-vitro proliferation,adhesion and migration of keratinocytes&endothelial cells,pDA-CSS@PRP were histologically revealed to accelerate wound healing with less scar via rapid angiogenesis,arrangement of more mature collagen,guiding cells to spread,etc.In conclusion,pDA-CSSs have potential to serve as a novel DRT capable of delivering PRP,which may foster full-thickness skin defect healing by means of a One-step strategy.Zijun Zheng Minxiong Li Pengwei Shi Yanbin Gao Jun Ma Yuchen Li Lei Huang Zhangfeifan Yang Lei Yang 2021Bioactive Materials2021,6,8:2
13Interacting plexcitons for designed ultrafast optical nonlinearity in a monolayer semiconductor显示文摘Searching for ideal materials with strong effective optical nonlinear responses is a long-term task enabling remarkable breakthroughs in contemporary quantum and nonlinear optics.Polaritons,hybridized light-matter quasiparticles,are an appealing candidate to realize such nonlinearities.Here,we explore a class of peculiar polaritons,named plasmon–exciton polaritons(plexcitons),in a hybrid system composed of silver nanodisk arrays and monolayer tungsten-disulfide(WS2),which shows giant room-temperature nonlinearity due to their deep-subwavelength localized nature.Specifically,comprehensive ultrafast pump–probe measurements reveal that plexciton nonlinearity is dominated by the saturation and higher-order excitation-induced dephasing interactions,rather than the well-known exchange interaction in traditional microcavity polaritons.Furthermore,we demonstrate this giant nonlinearity can be exploited to manipulate the ultrafast nonlinear absorption properties of the solid-state system.Our findings suggest that plexcitons are intrinsically strongly interacting,thereby pioneering new horizons for practical implementations such as energy-efficient ultrafast all-optical switching and information processing.Yuxiang Tang Yanbin Zhang Qirui Liu Ke Wei Xiang’ai Cheng Lei Shi Tian Jiang 2022Light(Science & Applications)2022,11,5:2
14An additively manufactured Al-14.1Mg-0.47Si-0.31Sc-0.17Zr alloy with high specific strength,good thermal stability and excellent corrosion resistance显示文摘A novel Al-14.1 Mg-0.47 Si-0.31 Sc-0.17 Zr alloy was applied in the printing process of selective laser melting(SLM),and the corresponding microstructural feature,phase identification,tensile properties and corrosion behavior of the Al Mg Si Sc Zr alloy were studied in detail.As fabricated at 160 W and 200 mm/s,the Mg content of bulk sample decreased to 11.7 wt%due to the element vaporization at high energy density,and the density of this additively manufactured Al Mg Si Sc Zr alloy was 2.538 g/cm^(3),which is4.2%8.5%lighter than that of other SLM-processed Al alloys.After heat-treated(HT)at 325℃and 6 h,the microstructure was almost unchanged with an alternate distribution of fine equiaxed crystals and coarse columnar crystals.Nano-sized Al3(Sc,Zr)and Mg_(2)Si phases precipitated dispersedly in the Al matrix,and the tensile strength increased from 487.6 MPa to 578.4 MPa for precipitation strengthening and fine grain strengthening.With a fine grain size of 2.53μm,an excellent corrosion resistance was obtained for the as-printed(AP)Al Mg Si Sc Zr alloy.While the corrosion resistance of HT sample decreased slightly for the formation of non-dense oxide layer and pitting corrosion induced by diffuse precipitation distribution.This SLM-printed Al Mg Si Sc Zr alloy with high specific strength,good thermal stability and excellent corrosion resistance has broad prospects for the aerospace and automotive applications.Jiang Bi Zhenglong Lei Yanbin Chen Xi Chen Nannan Lu Ze Tian Xikun Qin 2021Journal of Materials Science & Technology2021,,8:2
15Highly stable lithium anode enabled by self-assembled monolayer of dihexadecanoalkyl phosphate显示文摘Li has been considered as the ultimate anode material for high energy density secondary Li batteries.However,its practical application has been limited due to its low Coulombic efficiency(CE)and the formation of lithium dendrites.Recently,we have developed a microspherical Li-carbon nanotube(Li-CNT)composite material passivated with octadecylphosphonic acid(OPA)self-assembled monolayer(SAM)exhibiting suppressed lithium dendrite formation and improved environmental/electrochemical stability.In this work,we demonstrated the significantly enhanced passivation effects of a SAM using dihexadecanoalkyl phosphate(DHP),a molecule that is comprised of double hydrophobic alkyl chains and forms a denser SAM on surfaces with large curvature.As a result,the DHP SAM delivers superior environmental and electrochemical stability to the OPA passivated Li-CNT material.In specific,the DHP passivated Li-CNT composite(DHP-Li-CNT)delivers a high CE of 99.25%under a 33.3%depth of discharge(DOD)at 1 C,when it is paired with a LiFePO4 cathode.The evolution of the SAM during cycling and the effects of DOD and current density on the CE of the DHP-Li-CNT anode have also been investigated.The improved SAM passivation constitutes an important step in achieving the goal of practically applicable Li anodes.Lei Zheng Feng Guo Tuo Kang Jin Yang Ya Liu Wei Gu Yanfei Zhao Hongzhen Lin Yanbin Shen Wei Lu Liwei Chen 2020Nano Research2020,13,5:1

17Effectiveness of Liu-zi-jue exercise on coronavirus disease 2019 in the patients: a randomized controlled trial显示文摘OBJECTIVE: The aim of this study was to examine the effect of Liu-zi-jue exercise on the respiratory symptoms, quality of life, and mental health of patients with mild coronavirus disease 2019(COVID-19). METHODS: A single-center randomized controlled trial was conducted with 104 patients with mild COVID-19. The patients were randomly assigned to the Liu-zi-jue plus conventional therapy group and conventional therapy group. The outcome measures included Modified Borg Dyspnea Scale(MBDS) score, Patient Health Questionnaire-9(PHQ-9) score, Fatigue Scale-14(FS-14), respiratory symptoms, and vital signs. Data were collected on the first and sixth days of hospitalization and on the discharge day. RESULTS: Repeated-measures ANOVA revealed that the whole scales all showed a downward trend in the two groups(all P < 0.05). The results of single-group effect suggested that the whole scale score in the intervention group was significantly lower than that in the control group at the sixth day of hospitalization. Compared with the control group, only the MBDS, expectoration, and FS-14 scores showed significantly lower scores at the discharge day(P < 0.001, P = 0.011, P = 0.002). Comparison within the group showed that all the variables were significantly different at the three time points with a decreasing trend(P < 0.05), except for the PHQ-9 and expectoration scores(P = 0.331, 0.052). All patients’ vital signs remained within a stable normal range throughout the hospital stay. CONCLUSION: The results suggested that Liu-zi-jue exercise as a complementary and alternative therapy showed beneficial effects on improving the symptoms(shortness of breath, fatigue, and cough), quality of life, and mental health of patients with mild COVID-19.ZHU Qingguang ZHANG Shuaipan LI Jingxian SUN Wuquan CHENG Wei ZHAN Chao CHENG Yanbin FANG Lei FANG Min 2022Journal of Traditional Chinese Medicine2022,42,6:1
