| 2 | Dynamic response analysis under atmospheric disturbances for helicopters based on elastic blades显示文摘A flight dynamics model based on elastic blades for helicopters is developed.Modal shape analysis is used to describe the rotating elastic blades for the purpose of reducing the elastic degrees of freedom for blades.The analytical result is employed to predict the rotor forces and moments.The equilibrium equation of the flight dynamics model is then constructed for the elastic motion for blades and the rigid motion for other parts.The nonlinear equation is further simplified,and the gradient descent algorithm is adopted to implement the trim simulation.The trim analysis shows that the effect of blade elasticity on the accuracy of rotor forces and moments is apparent at high speed,and the proposed method presents good accuracy for trim performance.The timedomain response is realized by a combination of the Newmark method and the adaptive RungeKutta method.The helicopter control responses of collective pitch show that the response accuracy of the model at a yaw-and-pitch attitude is improved.Finally,the influence of blade elasticity on the helicopter dynamic response in low-altitude wind shear is investigated.An increase in blade elasticity reduces the oscillation amplitude of the yaw angle and the vertical speed by more than 70%.Compared with a rigid blade,an elastic blade reduces the vibration frequency of the angular velocity and results in a fast return of the helicopter to its stable flight. | Tong Liu Yuting Dai Guanxin Hong Linpeng Wang | 2017 | Chinese Journal of Aeronautics2017，30，2： | 4 |
| 3 | Pathogenesis of allergic diseases and implications for therapeutic interventions显示文摘Allergic diseases such as allergic rhinitis (AR), allergic asthma (AAS), atopic dermatitis (AD), food allergy (FA), and eczema aresystemic diseases caused by an impaired immune system. Accompanied by high recurrence rates, the steadily rising incidence ratesof these diseases are attracting increasing attention. The pathogenesis of allergic diseases is complex and involves many factors,including maternal-fetal environment, living environment, genetics, epigenetics, and the body’s immune status. The pathogenesisof allergic diseases exhibits a marked heterogeneity, with phenotype and endotype defining visible features and associatedmolecular mechanisms, respectively. With the rapid development of immunology, molecular biology, and biotechnology, manynew biological drugs have been designed for the treatment of allergic diseases, including anti-immunoglobulin E (IgE), antiinterleukin(IL)-5, and anti-thymic stromal lymphopoietin (TSLP)/IL-4, to control symptoms. For doctors and scientists, it is becomingmore and more important to understand the influencing factors, pathogenesis, and treatment progress of allergic diseases. Thisreview aimed to assess the epidemiology, pathogenesis, and therapeutic interventions of allergic diseases, including AR, AAS, AD,and FA. We hope to help doctors and scientists understand allergic diseases systematically. | Ji Wang Yumei Zhou Honglei Zhang Linhan Hu Juntong Liu Lei Wang Tianyi Wang Haiyun Zhang Linpeng Cong Qi Wang | 2023 | Signal Transduction and Targeted Therapy2023，8，4： | 3 |
| 4 | Orbital ordering and fluctuations in a kagome superconductor CsV_(3)Sb_(5)显示文摘Recently,competing electronic instabilities,including superconductivity and density-wave-like order,have been discovered in vanadium-based kagome metals AV_(3)Sb_(5)(A=K,Rb,Cs)with a nontrivial band topology.This finding stimulates considerable interest to study the interplay of these competing electronic orders and possible exotic excitations in the superconducting state.Here,we performed51V and133Cs nuclear magnetic resonance(NMR)measurements on a CsV_(3)Sb_(5)single crystal to clarify the nature of density-wave-like transition in these kagome superconductors.A first-order structural transition is unambiguously revealed below T_(s)~94 K by observing the sudden splitting of Knight shift in^(51)V NMR spectrum.Moreover,combined with^(133)Cs NMR spectrum,the present result confirms a three-dimensional structural modulation.By further analyzing the anisotropy of Knight shift and 1/T_(1)T at^(51)V nuclei,we proposed that the orbital order is the primary electronic order induced by the firstorder structural transition,which is supported by further analysis on electric field gradient at^(51)V nuclei.In addition,the evidence for possible orbital fluctuations is also revealed above T_(s).The present work sheds light on a rich orbital physics in kagome superconductors AV_(3)Sb_(5). | DianWu Song LiXuan Zheng FangHang Yu Jian Li LinPeng Nie Min Shan Dan Zhao ShunJiao Li BaoLei Kang ZhiMian Wu YanBing Zhou KuangLv Sun Kai Liu XiGang Luo ZhenYu Wang JianJun Ying XianGang Wan Tao Wu XianHui Chen | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，4： | 2 |
| 5 | Crack-based and Hair-like Sensors Inspired from Arthropods:A Review显示文摘Over a long period of time,arthropods evolve to have two excellent mechanical sensilla of slit sensilla and trichobothria sensilla,which construct a perfect perception system.The former mainly perceives the change of the in-the-plane force while the latter perceives that of the out-of-plane force.In recent years,these two sensilla have attracted researchers as the models for developing artificial mechanical sensors.This review mainly includes the biomechanics and biomimetic manufacturing techniques as well as their future application value.In order to better understand the advantages of biological strategies,this review describes the morphology,mechanical analysis,and information recognition of slit sensilla and trichobothria sensilla.Then this review highlights the recent development of Crack-based Sensors(CBSs)and Hair-like Sensors(HLSs)based on the analysis of biological mechanism.The manufacturing method and substrate of crack in CBS and those of hair rods in HLS are discussed respectively.Finally,the practical applications and potential value of two sensilla,such as flexible wearable electronic devices,robot sensing system,autopilot sensing and wind tunnel speed detection,are briefly discussed. | Changchao Zhang Junqiu Zhang Daobing Chen Xiancun Meng Linpeng Liu Kejun Wang Zhibin Jiao Tao Sun Dakai Wang Shichao Niu Zhiwu Han Luquan Ren | 2020 | Journal of Bionic Engineering2020，17，5： | 2 |
| 6 | Micro/nano-scale Characterization and Fatigue Fracture Resistance of Mechanoreceptor with Crack-shaped Slit Arrays in Scorpion显示文摘The nocturnal scorpion Heterometrus petersii uses Basitarsal Compound Slit Sensilla (BCSS) as mechanoreceptor to detect mechanical signal (e.g. substrate vibration, cyclic loads caused by walking) without fatigue failure such as initiation of fatigue crack and further propagation of crack-shaped slit. The outstanding perceptive function has been discovered for over half a century. However, it is not yet clear about the microstructure, material composition and micromechanical property which are all important factors that determine the fatigue fracture resistance of the BCSS. Here, the microscopic characteristics of the BCSS were thoroughly studied. The results dicate that anti-fatigue resilin and stiff chitinous cuticle form multilayered composite as the main body of the BCSS. Meanwhile, the pre-existing slit as mechanosensory structure is covered by cuticular membrane which has different mechanical property with the epicuticle. Theoretical analysis shows that the structure-composition-property synergistic relations of composites confer on the BCSS with extreme fatigue fracture tolerance. | Kejun Wang Junqiu Zhang Yuqiang Fang Daobing Chen Linpeng Liu Zhiwu Han Luquan Ren | 2019 | Journal of Bionic Engineering2019，16，3： | 1 |

| 8 | High-power mid-infrared femtosecond master oscillator power amplifier Er:ZBLAN fiber laser system显示文摘High-power femtosecond mid-infrared(MIR)lasers are of vast importance to both fundamental research and applications.We report a high-power femtosecond master oscillator power amplifier laser system consisting of a singlemode Er:ZBLAN fiber mode-locked oscillator and pre-amplifier followed by a large-mode-area Er:ZBLAN fiber main amplifier.The main amplifier is actively cooled and bidirectionally pumped at 976 nm,generating a slope efficiency of 26.9%.Pulses of 8.12 W,148 fs at 2.8μm with a repetition rate of 69.65 MHz are achieved.To the best of our knowledge,this is the highest average power ever achieved from a femtosecond MIR laser source.Such a compact ultrafast laser system is promising for a wide range of applications,such as medical surgery and material processing. | Linpeng Yu Jinhui Liang Qinghui Zeng Jiacheng Wang Xing Luo Jinzhang Wang Peiguang Yan Fanlong Dong Xing Liu Qitao Lü Chunyu Guo Shuangchen Ruan | 2023 | High Power Laser Science and Engineering2023，11，4： | 0 |
| 9 | Hepatic venous pressure gradient measurement guiding nonselective beta-blocker therapy in a patient with clinically significant portal hypertension显示文摘Clinically significant portal hypertension(CSPH),defined as a hepatic venous pressure gradient(HVPG)≥10 mmHg,is an independent risk factor for decompensated events in patients with compensated cirrhosis.Currently,the Baveno VII consensus recommends using nonselective beta-blockers to treat compensated cirrhosis in patients with CSPH.Here,we report a unusual case of compensated cirrhosis with CSPH caused by hepatitis B,and we successfully adjust NSBBs drug treatment strategies monitoring by HVPG results and achieve response standards.Timely adjustment of NSBBs drug treatment strategies based on HVPG test results for patients with CSPH can improve the final response rate. | Kun Wang Minghui Tian Linpeng Zhang Shanghao Liu Xiaoqing Guo Jianzhong Ma | 2023 | Portal Hypertension & Cirrhosis2023，2，2： | 0 |
| 10 | Generation of single solitons tunable from 3 to3.8μm in cascaded Er^(3+)-doped and Dy^(3+)-doped fluoride fiber amplifiers显示文摘High-power tunable femtosecond mid-infrared(MIR)pulses are of great interest for many scientific and industrial applications.Here we demonstrate a compact fluoride-fiber-based system that generates single solitons tunable from 3 to 3.8μm.The system is composed of an Er:ZBLAN fiber oscillator and amplifier followed by a fusion-spliced Dy:ZBLAN fiber amplifier.The Er:ZBLAN fiber amplifier acts as a power booster as well as a frequency shifter to generate Raman solitons up to 3μm.The Dy:ZBLAN fiber amplifier transfers the energy from the residual 2.8μm radiation into the Raman solitons using an in-band pumping scheme,and further extends the wavelength up to 3.8μm.Common residual pump radiation and secondary solitons accompanying the soliton self-frequency shift(SSFS)are recycled to amplify Raman solitons,consequently displaying a higher output power and pulse energy,a wider shifting range,and an excellent spectral purity.Stable 252 fs pulses at3.8μm with a record average power of 1.6 W and a pulse energy of 23 n J are generated.This work provides an effective way to develop high-power widely tunable ultrafast single-soliton MIR laser sources,and this method can facilitate the design of other SSFS-based laser systems for single-soliton generation. | LINPENG YU JINHUI LIANG SHITING HUANG JINZHANG WANG JIACHEN WANG XING LUO PEIGUANG YAN FANLONG DONG XING LIU QITAO LUE CHUNYU GUO SHUANGCHEN RUAN | 2022 | Photonics Research2022，10，9： | 0 |
| 11 | Combining biological denitrification and electricity generation in methane-powered microbial fuel cells显示文摘Methane has been demonstrated to be a feasible substrate for electricity generation in microbial fuel cells(MFCs)and denitrifying anaerobic methane oxidation(DAMO).However,these two processes were evaluated separately in previous studies and it has remained unknown whether methane is able to simultaneously drive these processes.Here we investigated the co-occurrence and performance of these two processes in the anodic chamber of MFCs.The results showed that methane successfully fueled both electrogenesis and denitrification.Importantly,the maximum nitrate removal rate was significantly enhanced from(1.4±0.8)to(18.4±1.2)mg N/(L·day)by an electrogenic process.In the presence of DAMO,the MFCs achieved a maximum voltage of 610 mV and a maximum power density of 143±12 mW/m^(2).Electrochemical analyses demonstrated that some redox substances(e.g.riboflavin)were likely involved in electrogenesis and also in the denitrification process.High-throughput sequencing indicated that the methanogen Methanobacterium,a close relative of Methanobacterium espanolae,catalyzed methane oxidation and cooperated with both exoelectrogens and denitrifiers(e.g.,Azoarcus).This work provides an effective strategy for improving DAMO in methane-powered MFCs,and suggests that methanogens and denitrifiers may jointly be able to provide an alternative to archaeal DAMO for methane-dependent denitrification. | Linpeng Yu Eryi Zhang Lin Yang Shiqi Liu Christopher Rensing Shungui Zhou | 2023 | Journal of Environmental Sciences2023，，8： | 0 |
| 12 | Epigenome-Metabolome-Epigenome signaling cascade in cell biological processes显示文摘Cell fate determination as a fundamental question in cell biology has been extensively studied at different regulatory levels for many years.However,the mechanisms of multilevel regulation of cell fate determination remain unclear.Recently,we have proposed an Epigenome-Metabolome-Epigenome(E-M-E)signaling cascade model to describe the cross-over cooperation during mouse somatic cell reprogramming.In this review,we summarize the broad roles of E-M-E signaling cascade in different cell biological processes,including cell differentiation and dedifferentiation,cell specialization,cell proliferation,and cell pathologic processes.Precise E-M-E signaling cascades are critical in these cell biological processes,and it is of worth to explore each step of E-M-E signaling cascade.E-M-E signaling cascade model sheds light on and may open a window to explore the mechanisms of multilevel regulation of cell biological processes. | Linpeng Li Keshi Chen Yi Wu Ge Xiang Xingguo Liu | 2022 | Journal of Genetics and Genomics2022，49，4： | 0 |
| 13 | Vibrational Receptor of Scorpion(Heterometrus petersii):The Basitarsal Compound Slit Sensilla显示文摘Recently,micro-vibrational perception mechanisms of nocturnal arthropods such as scorpions and spiders are attracting increasingly more attention and research.The relevant micro-vibrational receptors are exquisite,in terms of their comprehensive performance such as sensitivity,stability,high anti-interference,and ultralow-power consumption.In this work,we find the Basitarsal Compound Slit Sensilla (BCSS) of scorpion (Heterometrus petersii) are composed of the crack-shaped slits as mechanosensory structure and can efficiently detect substrate-borne vibrational signal in complex natural environment.The study on microstructures and mechanical properties of tissue phases constituting the BCSS reveals that the strategy of tessellation is used to make crack-shaped slit amplify the tiny mechanical signal.In addition,the magnitude-frequency characteristics of electrophysiological signals caused by vibration stimulation with different frequencies indicate that the scorpion is sensitive to micro-vibrational signals at a certain frequency range.Meanwhile,the vibrational perception mechanism based on geometrical amplification and resonance is proposed to explain how scorpions detect the tiny biotic vibrational signal efficiently in noise environment.This finding not only promotes our further understanding of ultra-sensitive mechanism of the vibrational receptors,but also provides biological inspiration for the next generation of mechanosensor for a broad range of applications. | Kejun Wang Junqiu Zhang Linpeng Liu Daobing Chen Honglie Song Yinliang Wang Shichao Niu Zhiwu Han Luquan Ren | 2019 | Journal of Bionic Engineering2019，16，1： | 0 |
