| 1 | High Sensitivity Acquisition Algorithm for DSSS Signal with Data Modulation显示文摘In direct sequence spread spectrum communication both for satelliteto-ground and inter-satellite links, the system constrains due to radio frequency spectral occupation, channel data throughput and link performances in terms of data channel coding which might result in a signal structure where the symbol duration is shorter than the pseudo code period. This can generate some difficulties in the DSSS signal acquisition due to the polarity inversion caused by the data modulation. To eliminate the influence due to polarity inversion, this paper proposes a novel acquisition algorithm based on the simultaneous search of the code phase, data phase and Doppler frequency. In the proposed algorithm the data phase is predicted and the correlation period for the coherent integration can be set equal to the symbol duration. Then non-coherent accumulation over different symbol is implemented in order to enhance the acquisition algorithm sensitivity; the interval of non-coherent accumulation is the least common multiple between the symbol duration and the pseudo code period. The algorithm proposed can largely minimize the SNR loss caused by data polarity inversion and enhance acquisition performance without a noticeable increase in hardware complexity. Theoretical analysis, simulation and measured results verify the validity of the algorithm. | SHEN Yuyao WANG Yongqing CHEN Jingyao WU Siliang | 2015 | China Communications2015，12，4： | 2 |
| 2 | ROS is essential for initiation of energy deprivation-induced autophagy显示文摘Autophagy is a highly conserved degradation process in which intracellular components are engulfed into a double membrane structure,known as the autophagosomes,and then delivered to lysosomes/vacuoles for degradation(Ohsumi,2014).Recently,autophagy has been found to be responsible for maintaining glucose homeostasis in adult animals(Karsli-Uzunbas et al.,2014).However,the molecular mechanism underlying energy deprivation-induced autophagy remains relatively unclear. | Choufei Wu Yixing Li Shu Zhong Yingcong Chen Yu Xie Yuyao Feng Weijing Yao Suping Fu Yanlan Zhu Liefeng Wang Yuting Chen Liqin Zhang Jingjing Tong Cong Yi | 2021 | Journal of Genetics and Genomics2021，48，6： | 1 |

| 7 | HDAC I/IIb selective inhibitor Purinostat Mesylate combined with GLS1 inhibition effectively eliminates CML stem cells显示文摘Purinostat Mesylate(PM)is a novel highly selective and active HDAC I/IIb inhibitor,and the injectable formulation of PM(PMF)based on the compound prescription containing cyclodextrin completely can overcome PM’s poor solubility and improves its stability and pharmacokinetic properties.Here,we showed that PM effectively repressed the survival of Ph+leukemia cells and CD34+leukemia cells from CML patients in vitro.In vivo studies demonstrated that PMF significantly prevented BCR-ABL(T315I)induced CML progression by restraining leukemia stem cells(LSCs),which are insensitive to chemotherapy and responsible for CML relapse.Mechanism studies revealed that targeting HDAC I/IIb repressed several important factors for LSCs survival including c-Myc,β-Catenin,E2f,Ezh2,Alox5,and mTOR,as well as interrupted some critical biologic processes.Additionally,PMF increased glutamate metabolism in LSCs by increasing GLS1.The combination of PMF and glutaminase inhibitor BPTES synergistically eradicated LSCs by altering multiple key proteins and signaling pathways which are critical for LSC survival and self-renewal.Overall,our findings represent a new therapeutic strategy for eliminating LSCs by targeting HDAC I/IIb and glutaminolysis,which potentially provides a guidance for PMF clinical trials in the future for TKI resistance CML patients. | Qiang Qiu Linyu yang Yunyu Feng Zejiang Zhu Ning Li Li Zheng Yuanyuan Sun Cong Pan Huandi Qiu Xue Cui Wei He Fang Wang Yuyao Yi Minghai Tang Zhuang Yang Yunfan Yang Zhihui Li Lijuan Chen Yiguo Hu | 2023 | Bioactive Materials2023，，3： | 1 |

| 9 | Trace Elements of Multi-stage Minerals and Titanite U-Pb Dating for the Gneisses from Liansan Island,Sulu UHPM Belt显示文摘Gneisses with anatectic characteristics from the Liansan island in the Sulu UHPM(ultra-high pressure metamorphic)belt were studied for petrography,titanite U-Pb dating and mineral geochemistry.Three origins of garnets are distinguished:metamorphic garnet,peritectic garnet and anatectic garnet,which are formed in the stages of peak metamorphism,retrograde anatexis and melt crystallization,respectively.The euhedral titanite has a high content of REE and high Th/U ratios,which is interpreted as indicating that it was newly-formed from an anatectic melt.The LA-ICP-MS titanite U-Pb dating yields 214-217 Ma ages for the titanite(melt)crystallization.The distribution of trace elements varies in response to the different host minerals at different stages.At the peak metamorphic stage,Y and HREE are mainly hosted by garnet,Ba and Rb by phengite,Sr,Nb,Ta,Pb,Th,U and LREE by allanite and Y,U and HREE by zircon.During partial melting,Y,Pb,Th,U and REE are released into the melt,which causes a dramatic decline of these element contents in the retrograde minerals.Finally,titanite absorbs most of the Nb,U,LREE and HREE from the melt.Therefore,the different stages of metamorphism have different mineral assemblages,which host different trace elements. | SONG Lihao CAO Yuting XIE Tianhe CHEN Yuyao GAO Yuan WANG Songjie LI Xuping | 2023 | Acta Geologica Sinica(English Edition)2023，97，6： | 0 |
| 10 | Influence of positive DC electric field on rime icing on the insulator and its experimental verification in the natural environment显示文摘The electric field imposes a significant effect on ice accretion on the insulator.The impact of an AC electric field on insulator icing in an artificial climate chamber has been addressed.Compared with AC,DC electric field exerts an attraction on supercooled water droplets,which is more detrimental to the power system.Moreover,the icing on energised insulators is rarely studied in the natural environment.In the present research,an electrical,fluid coupled‐field simulation was carried out on the insulator.The force characteristics and motion deviation features of water droplets at different positive DC electric field strengths were studied.On this basis,rime icing on the insulator energised with different positive DC voltages was investigated in the field.Results show that the charged droplet shifts along the electric field line under a positive DC voltage.The deviation degree of the droplet increases with the increment of the voltage and droplet size and decreases with an increase in wind speed.As the voltage rises,the surface roughness,icing amount and icing length of rime ice‐covered insulator increase.Consequently,compared with that without energisation,the local collision coefficient,icing amount and icing length increase by 17.6%,46.4%and 63.9%,respectively,under a 40 kV DC voltage. | Zongyuan Liu Yuyao Hu Xingliang Jiang Lei Chen Mingchen Chi Feiyan Han Chong Zhao | 2023 | High Voltage2023，8，5： | 0 |
| 11 | Fabrication of Graphene/Cu Composite by Chemical Vapor Deposition and Effects of Graphene Layers on Resultant Electrical Conductivity显示文摘Graphene(Gr)has unique properties including high electrical conductivity;Thus,graphene/copper(Gr/Cu)composites have attracted increasing attention to replace traditional Cu for electrical applications. However,the problem of how to control graphene to form desired Gr/Cu composite is not well solved. This paper aims at exploring the best parameters for preparing graphene with different layers on Cu foil by chemical vapor deposition(CVD)method and studying the effects of different layers graphene on Gr/Cu composite’s electrical conductivity. Graphene grown on single-sided and double-sided copper was prepared for Gr/Cu and Gr/Cu/Gr composites. The resultant electrical conductivity of Gr/Cu composites increased with decreasing graphene layers and increasing graphene volume fraction. The Gr/Cu/Gr composite with monolayer graphene owns volume fraction of less than 0.002%,producing the best electrical conductivity up to59.8 ×10^(6)S/m,equivalent to 104.5% IACS and 105.3% pure Cu foil. | Xinyue Liu Yaling Huang Yuyao Li Jie Liu Quanfang Chen | 2024 | Journal of Harbin Institute of Technology(New Series)2024，31，1： | 0 |
| 12 | Broadband 1T-polytype tantalum disulfide saturable absorber for solid-state bulk lasers显示文摘1T-polytype tantalum disulfide(1T-TaS_(2)),an emerging strongly correlated material,features a narrow bandgap of 0.2 e V,bridging the gap between zero-bandgap graphene and large-bandgap 2D nonlinear optical(NLO)materials.Combined with its intense light absorption,high carrier concentration,and high mobility,1T-TaS_(2) shows considerable potential for applications in broadband optoelectronic devices.However,its NLO characteristics and related applications have rarely been explored.Here,1T-TaS_(2) nanosheets are prepared by chemical vapor deposition.The ultrafast carrier dynamics in the 400–1100 nm range and broadband NLO performance in the 515–2500 nm range are systematically studied using femtosecond lasers.An obvious saturable absorption phenomenon is observed in the visible to IR range.The nonlinear absorption coefficient is measured to be-22.60±0.52 cm MW-1under 1030 nm,which is larger than that of other typical 2D saturable absorber(SA)materials(graphene,black phosphorus,and MoS_(2))under similar experimental conditions.Based on these findings,using 1T-TaS_(2) as a new SA,passively Q-switched laser operations are successfully performed at 1.06,1.34,and 1.94μm.The results highlight the promise of 1T-TaS_(2) for broadband optical modulators and provide a potential candidate material system for mid-IR nonlinear optical applications. | MENGXIA WANG HAILONG QIU TIANWEN YANG ZHENGPING WANG CHUANRUI ZHAO YUANAN ZHAO TING YU YUYAO JIANG MEILING CHEN YAFEI LIAN GE ZHANG HONGJUN LIU ZHANGGUI HU JIANDA SHAO | 2022 | Photonics Research2022，10，9： | 0 |
| 13 | From macro to microarchitecture:reviews and trends of SRAM-based compute-in-memory circuits显示文摘The rapid growth of CMOS logic circuits has surpassed the advancements in memory access,leading to significant“memory wall”bottlenecks,particularly in artificial intelligence applications.To address this challenge,compute-in-memory(CIM)has emerged as a promising approach to enhance the performance,area efficiency,and energy efficiency of computing systems.By enabling memory cells to perform parallel computations,CIM improves data reuse and minimizes data movement between the memory and the processor.This study conducts a comprehensive review of various domains of SRAM-based CIM macros and their associated computing paradigms.Additionally,it presents a survey of recent SRAM-CIM macros,with a specific focus on the key challenges and design tradeoffs involved.Furthermore,this research identifies potential future trends in SRAM-CIM macro-level design,including hybrid computing,precision enhancement,and operator reconfiguration.These trends aim to resolve the tradeoff between computational accuracy,energy efficiency,and support for diverse operators within the SRAM-CIM framework.At the microarchitecture level,two possible solutions for tradeoffs are proposed:chiplet integration and sparsity optimization.Finally,research perspectives are proposed for future development. | Zhaoyang ZHANG Jinwu CHEN Xi CHEN An GUO Bo WANG Tianzhu XIONG Yuyao KONG Xingyu PU Shengnan HE Xin SI Jun YANG | 2023 | Science China(Information Sciences)2023，66，10： | 0 |
| 14 | Sophisticated deep learning with on-chip optical diffractive tensor processing显示文摘Ever-growing deep-learning technologies are making revolutionary changes for modern life.However,conventional computing architectures are designed to process sequential and digital programs but are burdened with performing massive parallel and adaptive deep-learning applications.Photonic integrated circuits provide an efficient approach to mitigate bandwidth limitations and the power-wall brought on by its electronic counterparts,showing great potential in ultrafast and energy-free high-performance computation.Here,we propose an optical computing architecture enabled by on-chip diffraction to implement convolutional acceleration,termed“optical convolution unit”(OCU).We demonstrate that any real-valued convolution kernels can be exploited by the OCU with a prominent computational throughput boosting via the concept of structral reparameterization.With the OCU as the fundamental unit,we build an optical convolutional neural network(oCNN)to implement two popular deep learning tasks:classification and regression.For classification,Fashion Modified National Institute of Standards and Technology(Fashion-MNIST)and Canadian Institute for Advanced Research(CIFAR-4)data sets are tested with accuracies of 91.63%and 86.25%,respectively.For regression,we build an optical denoising convolutional neural network to handle Gaussian noise in gray-scale images with noise levelσ=10,15,and 20,resulting in clean images with an average peak signal-to-noise ratio(PSNR)of 31.70,29.39,and 27.72 dB,respectively.The proposed OCU presents remarkable performance of low energy consumption and high information density due to its fully passive nature and compact footprint,providing a parallel while lightweight solution for future compute-in-memory architecture to handle high dimensional tensors in deep learning. | YUYAO HUANG TINGZHAO FU HONGHAO HUANG SIGANG YANG HONGWEI CHEN | 2023 | Photonics Research2023，11，6： | 0 |
| 15 | An in-situ polymerized interphase engineering for high-voltage allsolid- state lithium-metal batteries显示文摘All-solid-state lithium batteries(ASSLBs)have attracted great interest due to their promising energy density and strong safety.However,the interface issues,including large interfacial resistance between electrode and electrolyte and low electrochemical stability of solid-state electrolytes against high-voltage cathodes,have restricted the development of high-voltage ASSLBs.Herein,we report an ASSLB with stable cycling by adopting a conformal polymer interlayer in-situ formed at the Li_(6.4)La_(3)Zr_(1.4)Ta_(0.6)O_(12)(LLZTO)–cathode interfaces.The polymer can perfectlyfill the voids and create a stable interface contact between LLZTO and cathodes.In addition,the electric field across the polymer interlayer is reduced compared with pure solid polymer electrolyte(SPE),which facilitates the electrochemical stability with high-voltage cathode.The all-solid-state Li|LLZTO-SPE|LiFe_(0.4)Mn_(0.6)PO_(4)(LMFP)cells achieve a low interface impedance,high specific capacity,and excellent cycling performance.This work presents an effective and practical strategy to rationally design the electrode–electrolyte interface for the application of high-voltage ASSLBs. | Lu Nie Shaojie Chen Mengtian Zhang Tianyi Gao Yuyao Zhang Ran Wei Yining Zhang Wei Liu | 2024 | Nano Research2024，17，4： | 0 |
| 16 | Ultrafast Carbonized Wood of Electrode-Scaled Aligned-Porous Structure for High-Performance Lithium Batteries显示文摘The use of carbonized wood in various functional devices is attracting considerable attention due to its low cost,vertical channels,and high electrical conduction.However,the conventional carbonization method requires a long processing time and an inert atmosphere.Here,a microwave-assisted ultrafast carbonization technique was developed that carbonizes natural wood in seconds without the need for an inert atmosphere,and the obtained aligned-porous carbonized wood provided an excellent electrochemical performance as an anode material for lithium-ion batteries.This ultrafast carbonization technique simultaneously produced ZnO nanoparticles during the carbonization process that were uniformly distributed on the alignedporous carbon.The hierarchical structure of carbonized wood functionalized with ZnO nanoparticles was used as a host for achieving high-performance lithium-sulfur batteries:the highly conductive carbonized wood framework with vertical channels provided good electron transport pathways,and the homogeneously dispersed ZnO nanoparticles effectively adsorbed lithium polysulfide and catalyzed its conversion reactions.In summary,a new method was developed to realize the ultrafast carbonization of biomass materials with decorated metal oxide nanoparticles. | Shaojie Chen Lu Nie Hongsheng Shi Xiangchen Hu Zeyu Wang Xinshui Zhang Yuyao Zhang Qilin Hu Tianyi Gao Yi Yu Wei Liu | 2023 | Transactions of Tianjin University2023，29，5： | 0 |
| 17 | High-contrast and real-time visualization of membrane proteins in live cells with malachite green-based fluorogenic probes显示文摘Imaging dynamics of membrane proteins of live cells in a wash-free and real-time manner has been a challenging task. Herein, we report unprecedented applications of malachite green(MG), an organic dye widely used in pigment industry, as a switchable fluorophore to monitor membrane enzymes or noncatalytic proteins in live cells. Conformationally flexible MG is non-fluorescent in aqueous solution, yet covalent binding with endogenous proteins of cells significantly enhances its fluorescence at 670 nm by restricting flexibility of dye. Integrating a phosphate-caged quinone methide precursor with MG yielded a covalent labeling fluorogenic probe, allowing real-time imaging of membrane alkaline phosphatase(ALP,a model catalytic protein) activity in live cells with over 100-fold enhancement of fluorescence intensity.Moreover, MG is also applicable to image non-catalytic protein by conjugation with protein-specific ligand. A fluorogenic probe consisted of c-RGDf K peptide and MG proved to be compatible with wash-free and real-time visualization of non-catalytic integrin α_(v)β_(3) in live cells with high contrast. | Yefeng Chen Chenghong Xue Jie Wang Minqiu Xu Yuyao Li Yiru Ding Heng Song Weipan Xu Hexin Xie | 2022 | Chinese Chemical Letters2022，33，3： | 0 |
| 18 | Practical Realization of Optimal Auxiliary Frequency Control Strategy of Wind Turbine Generator显示文摘Adding the auxiliary frequency control function to the wind turbine generator(WTG)is a solution to the frequency security problem of the power system caused by the replacement of the synchronous generator(SG)by the WTG.The auxiliary frequency control using rotor kinetic energy is an economical scheme because the WTG still runs at the maximum power point during normal operation.In this paper,the functional optimization model of the auxiliary frequency control strategy of WTG is established.The optimal auxiliary frequency control strategy is obtained by solving the model numerically.As for the practical realization of the control strategy,the coordination of the auxiliary frequency control with the maximum power point tracking(MPPT)control is studied.The practical auxiliary frequency control strategy is modified to adapt to different power disturbances in the system,and the parameter setting method is also proposed.The sensitivity of system frequency to control parameters is studied.Finally,the simulation results verify the effectiveness and practicability of the proposed control strategy. | Ming Sun Yong Min Xuejun Xiong Lei Chen Le Zhao Yuyao Feng Bingran Wang | 2022 | Journal of Modern Power Systems and Clean Energy2022，10，3： | 0 |

| 20 | Urban agriculture as nature-based solutions:Three key strategies to tackle emerging issues on food security in Chinese cities under climatic and non-climatic challenges显示文摘1Introduction Achieving food and water security,according to the United Nations Sustainable Development Goals(SDGs),only requires a minimal environmental cost(Batalini de Macedo et al.,2022).However,in terms of agriculture,blindly devoting efforts to offset low-productivity farming or production techniques and industries,without systematic water,fertiliser,farm residue,tillage,and fallow management,will eventually interrupt the carbon sink under the soil and escalate greenhouse gas emissions,which is not helpful to meeting global climate targets.Thus,sciencebased land management practices are essential to decouple agricultural productivity from greenhouse gas emissions(Buscardo et al.,2021). | Zhe ZHU Jiayu WANG Faith Ka Shun CHAN Yuyao XU Gang LI Mengxia XU Wei-Qiang CHEN Yong-Guan ZHU | 2023 | Frontiers of Engineering Management2023，10，4： | 0 |
