| 1 | Carbon isotope reversal of desorbed gas in Longmaxi shale of Jiaoshiba area,Sicuhan Basin显示文摘Through analysis of components and carbon isotope compositions of gas desorbed from shale cores,the carbon isotope reversal phenomenon in the shale gas from the Silurian Longmaxi Formation of Jiaoshiba area in Sichuan Basin were well studied.Results showed that compared with the wellhead gas,the desorbed gas from Longmaxi shale had significantly more wet components and more heavy carbon isotope values;carbon isotope values of each component became heavier with the desorption time,δ^(13)C_(1)values of different samples had maximum positive variations of 12.3-23.9‰,butδ^(13)C_(2)values only had maximum positive variations of 0.8e2.3‰,indicating carbon isotope values of methane changed more obviously than that of heavy hydrocarbon.The above results were consistent with previous results of shale core desorption experiments carried out by other researchers.Shale gas in strata might have no carbon isotope reversal,and the phenomenon thatδ^(13)C_(1)values changed more significantly thanδ^(13)C_(2)values during the core desorption was not caused by diffusion rate differences among different components,but mainly due to different desorption stages of methane and ethane,i.e.,the ethane was in its early desorption stage while the methane was in its later desorption stage;during the production process,phase differences among different components of alkane gas and differences in the desorption stages induced by adsorption,could be the major cause for total reversal of carbon isotopes of shale gas in Longmaxi Formation,but it also could not excluded that mixture of kerogen cracking gas and crude oil cracking gas probably had a partial or more major contribution to the carbon isotope reversal. | Hua Qin Xiaojun Fan Ming Liu Jingyu Hao Bo Liang | 2017 | Petroleum Research2017，2，2： | 7 |
| 2 | Terahertz wavefront shaping with multi-channel polarization conversion based on all-dielectric metasurface显示文摘Polarization manipulation of electromagnetic wave or polarization multiplexed beam shaping based on metasurfaces has been reported in various frequency bands.However,it is difficult to shape the beam with multi-channel polarization conversion in a single metasurface.Here,we propose a new method for terahertz wavefront shaping with multi-channel polarization conversion via all-silicon metasurface,which is based on the linear shape birefringence effect in spatially interleaved anisotropic meta-atoms.By superimposing the eigen-and non-eigen-polarization responses of the two kinds of meta-atoms,we demonstrate the possibility for high-efficiency evolution of several typical polarization states with two independent channels for linearly polarized waves.The measured polarization conversion efficiency is higher than 70%in the range of 0.9–1.3 THz,with a peak value of 89.2%at 1.1 THz.In addition,when more other polarization states are incident,combined with the integration of sub-arrays,we can get more channels for both polarization conversion and beam shaping.Simulated and experimental results verify the feasibility of this method.The proposed method provides a new idea for the design of terahertz multi-functional metadevices. | JIE LI CHENGLONG ZHENG JITAO LI GUOCUI WANG JINGYU LIU ZHEN YUE XUANRUO HAO YUE YANG FUYU LI TINGTING TANG YATING ZHANG YAN ZHANG JIANQUAN YAO | 2021 | Photonics Research2021，9，10： | 5 |
| 3 | Highly surface electron-deficient Co_(9)S_(8) nanoarrays for enhanced oxygen evolution显示文摘Tailoring valence electron delocalization of transition metal center is of importance to achieve highly-active electrocatalysts for oxygen evolution reaction(OER).Herein,we demonstrate a“poor sulfur”route to synthesize surface electron-deficient Co_(9)S_(8) nanoarrays,where the binding energy(BE)of Co metal center is considerably higher than all reported Co_(9)S_(8)-based electrocatalysts.The resulting Co_(9)S_(8) electrocatalysts only require the overpotentials(h)of 265 and 326 mV at 10 and 100 mA cm^(-2) with a low Tafel slope of 56 mV dec^-(1) and a 60 hlasting stability in alkaline media.The OER kinetics are greatly expedited with a low reaction activation energy of 27.9 kJ mol^-(1) as well as abundant OOH*key intermediates(24%),thus exhibiting excellent catalytic performances.The surface electron-deficient engineering gives an available strategy to improve the catalytic activity of other advanced non-noble electrocatalysts. | Haoxuan Zhang Jingyu Wang Qilin Cheng Petr Saha Hao Jiang | 2020 | Green Energy & Environment2020，5，4： | 3 |

| 7 | Nanoliposome-encapsulated caged-GABA for modulating neural electrophysiological activity with simultaneous detection by microelectrode arrays显示文摘Effective and precise neural modulation with real-time detection in the brain is of great importance and represents a significant challenge.Nanoliposome-encapsulated light-sensitive compounds have excellent characteristics such as high temporal and spatial resolution,delayed drug clearance,and restricted drug biodistribution for neural modulation.In this study,we developed a nanoliposome-based delivery system for ruthenium-based caged GABA compounds(Nanolipo-Ru)to modulate neural activity and allow for real-time monitoring using the microelectrode arrays(MEAs).The Nanolipo-Ru nanoparticles had an average size of 134.10±4.30 nm and exhibited excellent stability for seven weeks.For the in vivo experiment in the rat,release of GABA by Nanolipo-Ru under blue light illumination resulted in an average firing rate reduction in interneurons and pyramidal neurons in the same brain region of 79.4%and 81.6%,respectively.Simultaneously,the average power of local field potentials in the 0–15 Hz range degraded from 4.34 to 0.85 mW.In addition,the Nanolipo-Ru nanoparticles have the potential to provide more flexible timing of modulation than unencapsulated RuBi-GABA in the experiments.These results indicated that Nanolipo-Ru could be an effective platform for regulating neuronal electrophysiology.Furthermore,nanoliposomes with appropriate modifications would render promising utilities for targeting of specific types of neurons in the future. | Jingyu Xie Yilin Song Yuchuan Dai Ziyue Li Fei Gao Xuanyu Li Guihua Xiao Yu Zhang Hao Wang Zeying Lu Xingyu Jiang Wenfu Zheng Xinxia Cai | 2020 | Nano Research2020，13，6： | 0 |
| 8 | Proteomic characterization of four subtypes of M2 macrophages derived from human THP-1 cells显示文摘Macrophages are widely distributed immune cells that contribute to tissue homeostasis.Human THP-1 cells have been widely used in various macrophage-associated studies,especially those involving pro-inflammatory M1 and anti-inflammatory M2 phenotypes.However,the molecular characterization of four M2 subtypes(M2a,M2b,M2c,and M2d)derived from THP-1has not been fully investigated.In this study,we systematically analyzed the protein expression profiles of human THP-1-derived macrophages(M0,M1,M2a,M2b,M2c,and M2d)using quantitative proteomics approaches.The commonly and specially regulated proteins of the four M2 subtypes and their potential biological functions were further investigated.The results showed that M2a and M2b,and M2c and M2d have very similar protein expression profiles.These data could serve as an important resource for studies of macrophages using THP-1 cells,and provide a reference to distinguish different M2 subtypes in macrophage-associated diseases for subsequent clinical research. | Pengfei LI Chen MA Jing LI Shanshan YOU Liuyi DANG Jingyu WU Zhifang HAO Jun LI Yuan ZHI Lin CHEN Shisheng SUN | 2022 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2022，23，5： | 0 |
| 9 | A Natural Polymer Captor for Immobilizing Polysulfide/Polyselenide in Working Li-SeS_(2) Batteries显示文摘SeS_(2) has become a promising cathode material owing to its enhanced electrical conductivity over sulfur and higher theoretical specific capacity than selenium;however,the working Li-SeS_(2) batteries have to face the practical challenges from the severe shuttling of soluble dual intermediates of polysulfide and polyselenide,especially in high-SeS_(2)-loading cathodes.Herein,a natural organic polymer,Nicandra physaloides pectin(NPP),is proposed to serve as an effective polysulfide/polyselenide captor to address the shuttling issues.Informed by theoretical calculations,NPP is competent to provide a Lewis base-based strong binding interaction with polysulfides/polyselenides via forming lithium bonds,and it can be homogeneously deposited onto a three-dimensional double-carbon conductive scaffold to finally constitute a polysulfide/polyselenide-immobilizing interlayer.Operando spectroscopy analysis validates the enhanced polysulfide/polyselenide trapping and high conversion efficiency on the constructed interlayer,hence bestowing the Li-SeS_(2) cells with ultrahigh rate capability(448 mAh g^(−1)at 10 A g^(−1)),durable cycling lifespan(≈0.037%capacity attenuation rate per cycle),and high areal capacity(>6.5 mAh cm^(−2))at high SeS_(2) loading of 15.4 mg cm^(−2).Importantly,pouch cells assembled with this interlayer exhibit excellent flexibility,decent rate capability with relatively low electrolyte-to-capacity ratio,and stable cycling life even under a low electrolyte condition,promising a low-cost,viable design protocol toward practical Li-SeS_(2) batteries. | Yin Zhang Menglei Wang Yi Guo Lingzhi Huang Boya Wang Yunhong Wei Peng Jing Yueying Zhang Yun Zhang Qian Wang Jingyu Sun Hao Wu | 2021 | Nano-Micro Letters2021，13，7： | 0 |
| 10 | Histones of Neutrophil Extracellular Traps Induce CD11b Expression in Brain Pericytes Via Dectin-1 after Traumatic Brain Injury显示文摘The brain pericyte is a unique and indispensable part of the blood-brain barrier(BBB),and contributes to several pathological processes in traumatic brain injury(TBI).However,the cellular and molecular mechanisms by which pericytes are regulated in the damaged brain are largely unknown.Here,we show that the formation of neutrophil extracellular traps(NETs)induces the appearance of CD11b^(+)pericytes after TBI.These CD11b^(+)pericyte subsets are characterized by increased permeability and pro-inflammatory profiles compared to CD11b-pericytes.Moreover,histones from NETs by Dectin-1 facilitate CD11b induction in brain pericytes in PKC-c-Jun dependent manner,resulting in neuroinflammation and BBB dysfunction after TBI.These data indicate that neutrophil-NET-pericyte and histone-Dectin-1-CD11b are possible mechanisms for the activation and dysfunction of pericytes.Targeting NETs formation and Dectin-1 are promising means of treating TBI. | Yang-Wuyue Liu Jingyu Zhang Wanda Bi Mi Zhou Jiabo Li Tiantian Xiong Nan Yang Li Zhao Xing Chen Yuanguo Zhou Wenhui He Teng Yang Hao Wang Lunshan Xu Shuang-Shuang Dai | 2022 | Neuroscience Bulletin2022，38，10： | 0 |
| 11 | Numerical Study of Convective and Radiation Heat Transfer Characteristics in an Upward-Facing Cylindrical Cavity under Back-Side Windy Condition显示文摘Under the back-side windy condition,the convection and radiation heat transfer characteristics in an iso-flux upward-facing cylindrical cavity were studied by three-dimensional numerical simulation.The impacts of cavity tilt angle,wind incident angle and wind speed on convection and radiation heat transfer Nusselt number Nuc and Nur were analyzed,and the possible explanations for their impacts were presented.Results show that due to the disturbance of wind,the influence of cavity tilt angle becomes more complicated and is related to wind incident angle and wind speed.The variation of Nuc or Nur with wind incident angle is different for different cavity tilt angles.Despite of the changes of cavity tilt angle or wind incident angle,the Nuc increases with the wind speed while the Nur presents a declination with the increasing of wind speed.Hence,compared with cavity tilt angle and wind incident angle,wind speed may be the dominant factor affecting or controlling the convective and radiation heat transfer of cavity. | WANG Zehui WU Kefeng WANG Ti XIA Liangwei YU Qiang HUANG Ying SUN Hao WEI Guohua GUAN Jingyu YAN Yanfei | 2021 | Journal of Thermal Science2021，30，1： | 0 |
| 12 | Harmonized edge/graphitic-nitrogen doped carbon nanopolyhedron@nanosheet composite via salt-confined strategy for advanced K-ion hybrid capacitors显示文摘Nitrogen doping has readily emerged as an efficient solution to boost potassium-ion storage of carbonaceous materials.Nevertheless,the capacity and lifespan enhancement of derived electrodes is still plagued by the incompetent in coordinating the dopant configurations.In the realm of emerging potassium-ion hybrid capacitor(PIHC)device,dictating nitrogen doping to enhance pseudocapacitive behavior and improve K^(+)diffusion kinetics of carbonaceous anodes is scarcely demonstrated.Herein,we report the design of hierarchical N^(-)doped carbon nanopolyhedron@nanosheet composite via a salt-confined synthetic strategy with tunable doping configurations toward advanced PIHC anode.A harmonized edge-to graphitic-nitrogen ratio in such dual-carbon materials enables outstanding rate capability(130 mAh g^(-1) at 10.0 A g^(-1))and cyclic performance(with a capacity retention of 80%after 2000 cycles at 5.0 A g^(-1))in half-cell tests.As expected,the thus-assembled PIHC full device with a working voltage of 4.2 V presents a high energy/power density(146 Wh kg^(-1)/8000 W kg^(-1))and favorable cyclicability.This work is anticipated to offer an innovative insight into the coordination of nitrogen doping configurations in heteroatom-doped carbon anode targeting highperformance PIHC applications. | Yuyang Yi Hao Ma Xueyu Lian Qingqing Mei Zhihan Zeng Yu Zhao Chen Lu Wen Zhao Wenyue Guo Zhongfan Liu Jingyu Sun | 2021 | InfoMat2021，3，8： | 0 |
| 13 | Cooperative TDD reciprocity calibration with diversity combining for distributed large-scale MIMO systems显示文摘Thanks to channel reciprocity,the time-division duplexing operation is typically used for distributed large-scale multiple-input multiple-output systems.With the knowledge of uplink channel state,APs(Access Points)perform the downlink precoding to cooperatively communicate with multiple UEs(User Equipments).Unfortunately,the channel reciprocity is often jeopardized by the non-symmetric transceiver RF(Radio Frequency)circuits at both sides of the link.By excluding UEs from the calibration procedure,the TLS(Total Least Squares)method is extended to the case of partial calibration,where only the APs are involved to exchange calibration signals to compensate for RF mismatches.Nevertheless,channel fluctuations between APs significantly degrade system performance.Therefore,we propose a scheme to obtain the diversity gain,by performing a calibration with the combination of the calibration signals of different channel coherent times.Simulation results confirm the effective performance and robustness of our scheme. | Hao Wei Dongming Wang Jingyu Hua Junhui Zhao | 2017 | Journal of Communications and Information Networks2017，2，3： | 0 |
| 14 | Dynamic Visible Light Positioning Based on Enhanced Visual Target Tracking显示文摘In visible light positioning systems,some scholars have proposed target tracking algorithms to balance the relationship among positioning accuracy,real-time performance,and robustness.However,there are still two problems:(1)When the captured LED disappears and the uncertain LED reappears,existing tracking algorithms may recognize the landmark in error;(2)The receiver is not always able to achieve positioning under various moving statuses.In this paper,we propose an enhanced visual target tracking algorithm to solve the above problems.First,we design the lightweight recognition/demodulation mechanism,which combines Kalman filtering with simple image preprocessing to quickly track and accurately demodulate the landmark.Then,we use the Gaussian mixture model and the LED color feature to enable the system to achieve positioning,when the receiver is under various moving statuses.Experimental results show that our system can achieve high-precision dynamic positioning and improve the system’s comprehensive performance. | Xiangyu Liu Jingyu Hao Lei Guo Song Song | 2023 | China Communications2023，20，10： | 0 |
| 15 | Stress-unloading and gas migration improvement mechanism in the soft and hard interbedded coal seam using directional hydraulic flushing technology显示文摘To enhance gas drainage in the soft and hard interbedded(SHI)coal seam,it’s necessary to unload the insitu stress and improve its gas migration performance.In this research,a directional hydraulic flushing(DHF)technology was carried out.The stress-unloading and gas migration improvement mechanism was analyzed through numerical simulation,and systematic engineering tests were conducted to verify the gas drainage effect.The results show that the improvement of gas migration performance in the SHI coal seam is caused by a combined effect of seepage-improving and diffusion-improving.After DHF,stress-unloading and plastic failure could be achieved both in the soft coal(SC)sublayer and in the hard coal(HC)sublayer.However,the gas diffusion capacity improves significantly in the SC sublayer,while the gas seepage capacity improves notably in the HC sublayer.Meanwhile,the stress-unloading and gas migration improvement effect improves with the flushing radius and the thickness of the SC sublayer.Besides,after adopting the DHF technology,the gas drainage effect improved markedly.The borehole number dropped by 49%,the gas drainage ratio increased from 26.0%to 48.2%,and the average coal roadway excavation speed increased from 2.4 to 5.6 m/d. | Hao Zhang Yuanping Cheng Cunbao Deng Jingyu Jiang Lei Zhang Xiaoyu Yan Junwei Guo Suifang Wang | 2023 | International Journal of Mining Science and Technology2023，33，9： | 0 |
| 16 | Analysis of the Characteristics of the Low-level Jets in the Middle Reaches of the Yangtze River during the Mei-yu Season显示文摘Here,we analyze the characteristics and the formation mechanisms of low-level jets(LLJs)in the middle reaches of the Yangtze River during the 2010 mei-yu season using Wuhan station radiosonde data and the fifth generation of the European Centre for Medium-Range Weather Forecasts(ERA5)reanalysis dataset.Our results show that the vertical structure of LLJs is characterized by a predominance of boundary layer jets(BLJs)concentrated at heights of 900-1200 m.The BLJs occur most frequently at 2300 LST(LST=UTC+8 hours)but are strongest at 0200 LST,with composite wind velocities>14 m s^(-1).Synoptic-system-related LLJs(SLLJs)occur most frequently at 0800 LST but are strongest at 1100LST,with composite wind velocities>12 m s^(-1).Both BLJs and SLLJs are characterized by a southwesterly wind direction,although the wind direction of SLLJs is more westerly,and northeasterly SLLJs occur more frequently than northeasterly BLJs.When Wuhan is south of the mei-yu front,the westward extension of the northwest Pacific subtropical high intensifies,and the low-pressure system in the eastern Tibetan Plateau strengthens,favoring the formation of LLJs,which are closely related to precipitation.The wind speeds on rainstorm days are greater than those on LLJ days.Our analysis of four typical heavy precipitation events shows the presence of LLJs at the center of the precipitation and on its southern side before the onset of heavy precipitation.BLJs were shown to develop earlier than SLLJs. | Chunguang CUI Wen ZHOU Hao YANG Xiaokang WANG Yi DENG Xiaofang WANG Guirong XU Jingyu WANG | 2023 | Advances in Atmospheric Sciences2023，40，4： | 0 |
| 17 | Fabric computing: Concepts, opportunities, and challenges显示文摘With the advent of the Internet of Everything,people can easily interact with their environments immersively.The idea of pervasive computing is becoming a reality,but due to the inconvenience of carrying silicon-based entities and a lack of fine-grained sensing capabilities for human-computer interaction,it is difficult to ensure comfort,esthetics,and privacy in smart spaces.Motivated by the rapid developments in intelligent fabric technology in the post-Moore era,we propose a novel computing approach that creates a paradigm shift driven by fabric computing and advocate a new concept of non-chip sensing in living spaces.We discuss the core notion and benefits of fabric computing,including its implementation,challenges,and future research opportunities. | Min Chen Jia Liu Pan Li Hamid Gharavi Yixue Hao Jingyu Ouyang Jiayu Hu Long Hu Chong Hou Iztok Humar Lei Wei Guang-Zhong Yang Guangming Tao | 2022 | The Innovation2022，3，6： | 0 |
| 18 | Prevalence of hepatic steatosis and metabolic associated fatty liver disease among female breast cancer survivors显示文摘To the Editor:Non-alcoholic fatty liver disease(NAFLD)comes to prevail in Asia and,the prevalence in China is reported tobe24%to36%.lilThe prevalence ofNAFLD and its associated medical burden might be underestimated.The diagnosis of NAFLD led to the exclusion of other chronic liver diseases including“excess”alcohols,thus the population with alcoholic consumptions or other liver diseases might be neglected.In March 2020,the international expert consensus proposed a new concept,“metabolic associated fatty liver disease(MAFLD),”“and replaced the earlier term” of NAFLD.2As themost prevalent female malignancy,breast cancer(BC)shares similar risk factors to MAFLD.Higher levels of obesity and physical inactivity are closely correlated to BC and are significant drive for the increasing trends in the prevalence of BC.Some BC survivors may receive chemotherapy and endocrine therapy,both of which are reported to increase the risk of hepatic steatosis(HS),which is the fundamental criteria of the diagnosis of MAFLD. | Shen Tian Hao Li Renhua Li Liang Ran Shu Li Juan Wu Zhou Xu Xinyu Liang Yuling Chen Jun Xiao Jiaying Wei Chenyu Ma Jingyu Song Ruiling She Kainan Wu Lingquan Kong | 2022 | Chinese Medical Journal2022，135，19： | 0 |
