| 1 | High-dimensional orbital angular momentum multiplexing nonlinear holography显示文摘Nonlinear holography has been identified as a vital platform for optical multiplexing holography because of the appearance of new optical frequencies.However,due to nonlinear wave coupling in nonlinear optical processes,the nonlinear harmonic field is coupled with the input field,laying a fundamental barrier to independent control of the interacting fields for holography.We propose and experimentally demonstrate high-dimensional orbital angular momentum(OAM)multiplexing nonlinear holography to overcome this problem.By dividing the wavefront of the fundamental wave into different orthogonal OAM channels,multiple OAM and polarization-dependent holographic images in both the fundamental wave and second-harmonic wave have been reconstructed independently in the spatial frequency domain through a type-II second harmonic generation process.Moreover,this method can be easily extended to cascadedχ2 nonlinear optical processes for multiplexing in more wavelength channels,leading to potential applications in multicasting in optical communications,multiwavelength display,multidimensional optical storage,anticounterfeiting,and optical encryption. | Xinyuan Fang Haocheng Yang Wenzhe Yao Tianxin Wang Yong Zhang Min Gu Min Xiaoa | 2021 | Advanced Photonics2021，3，1： | 8 |
| 2 | Formation of hierarchical Fe7Se8 nanorod bundles with enhanced sodium storage properties显示文摘Ordered hierarchical architectures are attractive candidates for electrochemical energy storage applications.Herein,a facile self-template strategy is applied to prepare Fe7Se8 architectures with a monolithic structure via a self-synthesized single precursor and subsequent calcination at high temperature.With the support of oleylamine,the precursor is structurally targeted to engineer the Fe7Se8 microstructure,featuring nanorod bundles arranged along the longitudinal direction.Because of their ordered hierarchical structure,the Fe7Se8 nanorod bundles deliver a high reversible capacity of 300 m Ah g^-1 at 0.5 A g^-1,along with exceptional rate capability up to 20 A g^-1 and long-term cycle life over 8000 cycles,which represents the highest stability of Fe7Se8 anodes for sodium-ion batteries reported to date.The feasibility of the present strategy to prepare metal selenide structures highlights its promising potential for the rational and effective engineering of electrode materials responsible for the electrochemical performance of energy storage systems. | Wenzhi Tian Wenzhe Ma Zhenyu Feng Fang Tian Haibo Li Jing Liu | 2020 | Journal of Energy Chemistry2020，29，5： | 2 |
| 3 | Hepatitis B virus hijacks CTHRC1 to evade host immunity and maintain replication显示文摘HepatitisBvirus(HBV)infection causes acuteand chronic liver diseases,but is not directly cytopathic.Liver injury results fromrepeated attempts of the cellular immune response system to control the viral infection.Here,we investigate the roles of cellular factors and signaling pathways involved in the regulation of HBV replication to reveal the mechanism underlying HBV infection and pathogenesis.Weshowthat collagen triple helix repeat containing 1(CTHRC1)expression is elevated in HBV-infected patients andin HBV-transfected cells through epigenetic modification and transcriptional regulation.CTHRC1 facilitates HBV replication in cultured cells and BALB/c mice by activating the PKCa/ERK/JNK/c-Jun cascade to repress the IFN/JAK/STAT pathway.HBV-activated CTHRC1 downregulates the activityof typeI interferon(IFN),theproductionof IFN-stimulatedgenes(ISGs),andthephosphorylationofsignal transducerandactivator of transcription 1/2(STAT1/2),whereas it upregulates the phosphorylation and ubiquitination of type I IFN receptors(IFNARa/b).Thus,our results showthat HBV uses a novelmechanismto hijack cellular factors and signal cascades in order to evade host antiviral immunity and maintain persistent infection.We also demonstrate that CTHRC1 has a novel role in viral infection. | Lan Bai Wei Zhang Li Tan Hongchuan Yang Maolin Ge Chengliang Zhu Rui Zhang Yanhua Cao Junbo Chen Zhen Luo Wenzhe Ho Fang Liu Kailang Wu Jianguo Wu | 2015 | Journal of Molecular Cell Biology2015，7，6： | 2 |

| 5 | Towards resilient average consensus in multi-agent systems:a detection and compensation approach显示文摘Consensus is one of the fundamental distributed control technologies for collaboration in multi-agent systems such as collaborative handling in intelligent manufacturing.In this paper,we study the problem of resilient average consensus for multi-agent systems with misbehaving nodes.To protect consensus value from being influenced by misbehaving nodes,we address this problem by detecting misbehaviors,mitigating the corresponding adverse impact,and achieving the resilient average consensus.General types of misbehaviors are considered,including attacks,accidental faults,and link failures.We characterize the adverse impact of misbehaving nodes in a distributed manner via two-hop communication information and develop a deterministic detection compensation based consensus(D-DCC)algorithm with a decaying fault-tolerant error bound.Considering scenarios wherein information sets are intermittently available due to link failures,a stochastic extension named stochastic detection compensation based consensus(S-DCC)algorithm is proposed.We prove that D-DCC and S-DCC allow nodes to asymptotically achieve resilient accurate average consensus and unbiased resilient average consensus in a statistical sense,respectively.Then,the Wasserstein distance is introduced to analyze the accuracy of S-DCC.Finally,extensive simulations are conducted to verify the effectiveness of the proposed algorithms. | Chongrong FANG Wenzhe ZHENG Zhiyu HE Jianping HE Chengcheng ZHAO Jingpei WANG | 2024 | Frontiers of Information Technology & Electronic Engineering2024，25，2： | 0 |

| 7 | SHARAD study on the structures and permittivity of a buried impact crater in Martian Central Elysium Planitia显示文摘The Elysium Planitia,located in the transition zone between the northern and southern hemispheres,is one of the key areas for studying the stratigraphic structure and geological history of Mars.Previous studies have shown that this plain has undergone complex surface modification processes including fluvial and volcanic processes,and systematic progress has been made in the study of macro-geological processes.However,there are relatively few studies on the regional structure of the plain,which restricts our understanding of the regional geological processes.A buried impact crater in the central part of the Elysium Planitia could have recorded the surface modification process since the formation of the impact crater,however,it is difficult to distinguish the subsurface stratigraphy due to the weak orbital radar reflection signal.In this study,we denoised Shallow Radar data and obtained a radargram with clear subsurface reflectors.We estimated the permittivity of subsurface materials via a multilayer reflection model.The results show that two subsurface reflectors divide the structure of the buried impact crater into three layers(overlying layer,underlying layer,and bottom layer).The shallow subsurface reflector covers almost the whole impact crater,while the deep subsurface reflector covers only the southwest part of the impact crater.Combining the permittivity inversion results with the geological background of lava activity in the Elysium Planitia area,we argue that the overlying layer may be a mixture of regolith and lava flow with low density,while the underlying layer and bottom layer are dense lava flows.The reflector between the underlying layer and bottom layer is probably a thin deposit derived from weathering between two lava activities,and its possible formation mechanism is as follows:the crater rim and peripheral ejecta has undergone relatively strong wind erosion and the eroded material was transport to the southwestern part of the impact crater,forming continuous thin deposits,between the emplacements of two lava flows.This is consistent with the wind erosion environment prevailing at low latitudes in the Late Amazonian of Mars.This study uses processed orbital radar data,dielectric property inversion,and geological structure interpretation of regional buried impact craters as a local example to demonstrate how radar data can be used to understand regional depositional processes,and it serves as a reference for studying the geological history of similar regional structures on Mars. | Peng FANG Wenzhe FA Jinhai ZHANG Yangting LIN | 2023 | Science China Earth Sciences2023，66，11： | 0 |
