| 1 | Stability of weak solutions to climate dynamics model with effects of topography and non-constant external force显示文摘In this paper, a climate dynamics model with the effects of topography and a non-constant external force, which consists of the Navier-Stokes equations and a temperature equation arising from the evolution process of the atmosphere, was considered.Under certain assumptions imposed on the initial data and by using some delicate estimates and compactness arguments, we proved the L^1-stability of weak solutions to the atmospheric equations. | LIAN RuXu ZENG QingCun JIN JiangBo | 2018 | Science China Earth Sciences2018，61，1： | 6 |
| 2 | Crystal structure of SARS-CoV-2 main protease in complex with protease inhibitor PF-07321332显示文摘Dear Editor,Since December 2019,the pandemic of coronavirus disease 2019(COVID-19)has taken a heavy toll on global health,creating an urgent need to develop effective strategies for prevention and treatment.The etiological agent,known as severe acute respiratory syndrome coronavirus 2(SARSCoV-2),has infected nearly 229.2 million people worldwide with more than 4.7 million deaths as of September 15,2021.Older age and preexisting health conditions are associated with worse clinical prognosis including higher mortality rates(Zhou et al.,2020).The global race to combat this pandemic has led to rapid deployment of numerous effective vaccines against SARS-CoV-2(Tregoning et al.,2021).However,the emergence of viral variants,including the Delta variant(B.1.617.2),compromised vaccine effectiveness with resurgence of SARS-CoV-2 infection among highly vaccinated population(Keehner et al.,2021).Therefore,development of therapeutics against the more conserved viral targets would be essential to contain the spread of COVID-19 and reduce mortality. | Yao Zhao Chao Fang Qi Zhang Ruxue Zhang Xiangbo Zhao Yinkai Duan Haofeng Wang Yan Zhu Lu Feng Jinyi Zhao Maolin Shao Xiuna Yang Leike Zhang Chao Peng Kailin Yang Dawei Ma Zihe Rao Haitao Yang | 2022 | Protein & Cell2022，13，9： | 6 |
| 3 | Selective Electrochemical Reduction of Nitrogen to Ammonia by Adjusting the Three-Phase Interface显示文摘The electrochemical nitrogen reduction reaction(NRR)provides a sustainable and alternative avenue to the Haber-Bosch process for ammonia(NH_(3))synthesis.Despite the great efforts made on catalysts and electrolytes,unfortunately,current NRR suffers from low selectivity due to the overwhelming competition with the hydrogen evolution reaction(HER).Here,we present an adjusted three-phase interface to enhance nitrogen(N_(2))coverage on a catalyst surface and achieve a record-high Faradic efficiency(FE)up to 97%in aqueous solution.The almost entirely suppressed HER process combined with the enhanced NRR activity,benefiting from the efficient three-interface contact line,is responsible for the excellent selectivity toward NH_(3),as evidenced by the theoretical and experimental results.Our strategy also demonstrates the applicability to other catalysts that feature strong H adsorption ability,to boost the FE for NH_(3) synthesis above 90%and to improve the NRR activity by engineering the catalysts. | Haiyan Wang Yuzhuo Chen Ruxue Fan Jiadong Chen Zhe Wang Shanjun Mao Yong Wang | 2019 | Research2019，，1： | 4 |
| 4 | Modeling and numerical simulation of a novel solar-powered absorption air conditioning system driven by a bubble pump with energy storage显示文摘This paper presents a novel solar-powered absorption air conditioning system driven by a bubble pump with energy storage. It solves the problem of unreliable solar energy supply by storing the working fluids and hence, functions 24 h per day. First, the working principles are described and the dynamic models for the primary energy storage components are developed. Then, the system is evaluated based on a numerical simulation. Based on the meteorological data of a typical day in a subtropical area, with the area of a solar collector being set at 19.15 m2, whilst the initial charging mass, mass fraction and temperature of the solution are respectively set at 379.5 kg, 54.16% and 34.5 ℃, it is found that the respective coefficients of performance (COP) of the air conditioning system and the en- tire system (including the solar panel) are 0.7771 and 0.4372. In particular, the energy storage density of the system is 206.69 MJ/m3 which is much greater than those of chilled water or hot water storage systems under comparable conditions. This makes the new system much more compact and efficient. Finally, an automatic control strategy is given to achieve the highest COP when solar energy fluctuates. | QIU Jia LIANG Jian CHEN GuangMing DU RuXu | 2009 | Chinese Science Bulletin2009，54，3： | 4 |
| 5 | Clinical classification and gene mutation of Chinese probands with Charcot-Marie-Tooth disease Analysis of 57 cases显示文摘Charcot-Marie-Tooth(CMT) disease is the most common inherited peripheral neuropathic disorder.CMT is clinically and genetically heterogeneous.To date,27 genes associated with the disease have been cloned.The present study carried out clinical classification according to clinical,electrophysiological and pathological features,conducted inheritance classification according to inheritance patterns,and performed mutation analysis of 13 CMT disease genes(PMP22,CX32,HSPB1,MNF2,MPZ,HSPB8,GDAP1,NFL,EGR2,SIMPLE,RAB7,LMNA,MTMR2) in 57 Chinese probands with CMT.Five cases of AD-CMT1 and 13 cases of sporadic CMT1 were diagnosed as CMT1A;five cases of X-CMT1,one case of X-CMT2 and one case of sporadic CMT1 were diagnosed as CMTX1;four cases of AD-CMT2 were diagnosed as CMT2F;one case of AD-CMT2 and one case of sporadic CMT2 were diagnosed as CMT2A2;one case of AD-CMT2 was diagnosed as CMT2L;one case of AD-CMT2 was diagnosed as CMT2J;one case of AR-CMT1 was diagnosed as CMT4A.Among the 57 CMT probands,seven genotypes were determined among 34 patients,with a detection rate of 59.6%.The results indicated that the clinical classification and inheritance classification are indispensable for selecting potential disease genes for mutation detection,and for efficient molecular diagnosis. | Ruxu Zhang Xiaobo Li Xiaohong Zi Shunxiang Huang Fufeng Zhang Kun Xia Qian Pan Beisha Tang | 2011 | Neural Regeneration Research2011，6，9： | 4 |
| 6 | Central Pattern Generator(CPG)Control of a Biomimetic Robot Fish for Multimodal Swimming显示文摘This paper introduces the design and control of a biomimetic robot fish for multimodal swimming.The biomimetic design consists of three parts:the rigid head,the wire-driven body and the compliant tail.The control is an improved Central Pattern Generator(CPG)with the high-level control command:(M,co,B,R),where M is the amplitude,co is the angular velocity,B is the offtet and R is the time ratio between two phases forming one flapping cycle.This method differs from previous research in two aspects:(1)The CPG control is firstly implemented on the wire-driven robot fish.(2)The improved CPG model synthesizes symmetrical flapping in cruising and asymmetrical flapping in turning for the robot fish.The asymmetrical flapping refers to the asymmetry of the offset and the time ratio.This combination of the design and the control has several advantages over the existing multimodal swimming robot fishes.First,it uses just one driving motor for undulatory oscillation while the others need to use two or more motors.Second,with just one motor,the CPG control can be easily implemented.Third,the use of the time ratio,R,makes the robot fish turn more naturally and effectively.Experimental results show the robot fish achieved the maximum speed of 1.37 Body Length/Second(BL.s-1)and the largest turning rate of 4577s.Additionally,in many swimming conditions,its Strouhal Number falls in the range from 0.2 to 0.4,which implies the robot fish is efficient. | Fengran Xie Yong Zhong Ruxu Du Zheng Li | 2019 | Journal of Bionic Engineering2019，16，2： | 4 |

| 8 | Intermediate Charcot-Marie-Tooth disease显示文摘Charcot-Marie-Tooth(CMT) disease is a common neurogenetic disorder and its heterogeneity is a challenge for genetic diagnostics. The genetic diagnostic procedures for a CMT patient can be explored according to the electrophysiological criteria: very slow motor nerve conduction velocity(MNCV)(<15 m/s), slow MNCV(15–25 m/s), intermediate MNCV(25–45 m/s), and normal MNCV(>45 m/s). Based on the inheritance pattern, intermediate CMT can be divided into dominant(DI-CMT) and recessive types(RI-CMT). GJB1 is currently considered to be associated with X-linked DI-CMT, and MPZ, INF2, DNM2, YARS, GNB4, NEFL, and MFN2 are associated with autosomal DI-CMT. Moreover, GDAP1, KARS, and PLEKHG5 are associated with RI-CMT. Identification of these genes is not only important for patients and families but also provides new information about pathogenesis. It is hoped that this review will lead to a better understanding of intermediate CMT and provide a detailed diagnostic procedure for intermediate CMT. | Lei Liu Ruxu Zhang | 2014 | Neuroscience Bulletin2014，30，6： | 3 |

| 10 | Bioinspired Closed-loop CPG-based Control of a Robot Fish for Obstacle Avoidance and Direction Tracking显示文摘This paper presents a study on bioinspired closed-loop Central Pattern Generator(CPG)based control of a robot fish for obstacle avoidance and direction tracking.The biomimetic robot fish is made of a rigid head with a pair of pectoral fins,a wire-driven active body covered with soft skin,and a compliant tail.The CPG model consists of four input parameters:the flapping amplitude,the flapping angular velocity,the flapping offset,and the time ratio between the beat phase and the restore phase in flapping.The robot fish is equipped with three infrared sensors mounted on the left,front and right of the robot fish,as well as an inertial measurement unit,from which the surrounding obstacles and moving direction can be sensed.Based on these sensor signals,the closed-loop CPG-based control can drive the robot fish to avoid obstacles and to track designated directions.Four sets of experiments are presented,including avoiding a static obstacle,avoiding a moving obstacle,tracking a designated direction and tracking a designated direction with an obstacle in the path.The experiment results indicated that the presented control strategy worked well and the robot fish can accomplish the obstacle avoidance and direction tracking effectively. | Jiayong Chen Bo Yin Chengcai Wang Fengran Xie Ruxu Du Yong Zhong | 2021 | Journal of Bionic Engineering2021，18，1： | 2 |
| 11 | Medical Additive Manufacturing: From a Frontier Technology to the Research and Development of Products显示文摘1.Research and development(R&D)and the challenges of raw materials for medical additive manufacturing Raw materials for medical additive manufacturing have a wide range of commonalities that are also seen in many other fields,making them an important basis in the field of three-dimensional(3D)printing.Problems and challenges related to material types,powder properties,formability,viscoelasticity,and so forth also share common features.For example,many metal materials are used in the field of aviation,while metals,polymers,and inorganic materials are used in the field of biomedicine.The most widely used materials in biomedicine are biocompatible.Various homogeneous and non-homogeneous composites are also available for 3D printing,and impose an additional challenge in additive manufacturing;the use of heterogeneous composites in 3D printing is particularly challenging. | Guixing Qiu Wenjiang Ding Wei Tian Ling Qin Yu Zhao Lianmeng Zhang Jian Lu Daijie Chen Guangyi Yuan Chengtie Wu Bingheng Lu Ruxu Du Jimin Chen Mo Elbestawi Zhongwei Gu Dichen Li Wei Sun Yuanjin Zhao Jie He Dadi Jin Bin Liu Kai Zhang Jianmo Li Kam WLeong Dewei Zhao Dingjun Hao Yingfang Ao Xuliang Deng Huilin Yang ShaoKeh Hsu Yingqi Chen Long Li Jianping Fan Guohui Nie Yun Chen Hui Zeng Wei Chen Yuxiao Lai | 2020 | Engineering2020，6，11： | 1 |

| 18 | Influence of mixed organic cations on the nonlinear optical properties of lead tri-iodide perovskites显示文摘Metal halide perovskite materials have been widely studied recently due to their excellent optoelectronic properties.Among these materials,organic-inorganic hybrid perovskites have attracted much attention because of their relatively soft framework,which makes them more suitable for nonlinear optical(NLO)applications.However,there is rare physical mechanism study on the coexistence of two-photon absorption(TPA)and saturable absorption(SA)in organic-inorganic hybrid perovskite materials.To clarify this issue,the NLO properties of mixed cation perovskite MA1-xFAxPbI3[MA=CH3NH3,FA=CH(NH2)2,x=0,0.2,0.4,0.6,and 0.8]thin films are investigated in this paper.Based on the nonlinear transmittance and femtosecond-transient absorption spectrum measurements,it is found that the MA1-xFAxPbI3 materials exhibit NLO behavior dependent on excitation intensity.The TPA coefficient of MA1-xFAxPbI3 decreases with the increase of formamidinium(FA)content,while the relevant saturable intensity increases.In addition,it is revealed that the linear absorption process from valence band 2 to valance band 1 still exists even under a very low excitation intensity.With the increase of excitation intensity,the light transmittance at 1300 nm decreases first and then increases sharply,which also supports the explanation for the coexistence of TPA and SA.It is expected that our findings will promote the application of perovskite materials in nonlinear optoelectronic devices. | XUANYU ZHANG SHUYU XIAO RUXUE LI TINGCHAO HE GUICHUAN XING AND RUI CHEN | 2020 | Photonics Research2020，8，9： | 1 |
