| 1 | Compressed sensing digital receiver and orthogonal reconstructing algorithm for wideband ISAR radar显示文摘This paper proposes a novel design of intermediate frequency(IF) digital receiver for wideband inverse synthetic aperture radar(ISAR) based on compressed sensing(CS). For the convenience in engineering application, we use random sampling in the digital receiver and make it possible to digitize the wideband IF signal using a commercial off-the-shelf analog-to-digital converter with sub-Nyquist sample rate. Besides, a novel basis for the sparse representation of real-valued ISAR radar echoes is built in this paper, and an orthogonal CS reconstructing algorithm is proposed based on this. Using our proposed method, the complex-valued range profile of target can be directly reconstructed from the subsampled real raw echo. The phase information of target range profile, which is very important for the coherent processing in ISAR imaging, is well reserved during the reconstruction. As a result, the down converter and matched filter, which are essential in conventional radar receiver, can be eliminated in our CS digital receiver. A series of simulation validates our design and demonstrates the feasibility of the sub-Nyquist sampling. The simulation results of ISAR imaging verify the validity and superiority of the proposed orthogonal reconstructing method. | HOU QingKai LIU Yang FAN LiJie SU ShaoYing | 2015 | Science China(Information Sciences)2015，58，2： | 4 |
| 2 | Difficult and complicated oral ulceration:an expert consensus guideline for diagnosis显示文摘The complexity of oral ulcerations poses considerable diagnostic and therapeutic challenges to oral specialists.The expert consensus was conducted to summarize the diagnostic work-up for difficult and complicated oral ulcers,based on factors such as detailed clinical medical history inquiry,histopathological examination,and ulceration-related systemic diseases screening.Not only it can provide a standardized procedure of oral ulceration,but also it can improve the diagnostic efficiency,in order to avoid misdiagnosis and missed diagnosis. | Xin Zeng Xin Jin Liang Zhong Gang Zhou Ming Zhong Wenmei Wang Yuan Fan Qing Liu Xiangmin Qi Xiaobing Guan Zhimin Yan Xuemin Shen Yingfang Wu Lijie Fan Zhi Wang Yuan He Hongxia Dan Jiantang Yang Hui Wang Dongjuan Liu Hui Feng Kai Jiao Qianming Chen | 2022 | International Journal of Oral Science2022，14，2： | 2 |
| 3 | Maiden Flight of Long March 7--The New Generation Medium Launch Vehicle in China显示文摘On June 25, 2016, the Long March 7(LM-7) launch vehicle completed its maiden flight successfully. LM-7, as a new generation of medium and basic launch vehicle based on the design concepts of non-toxic and nonpolluting, was developed for the purpose of launching a cargo spacecraft to the Chinese space station. Based on the experience on launching cargo spacecraft and satellites, LM-7 can be adapted for mainstream satellite launch missions in the future with its characteristics of serialization and continuous optimization. LM-7 is expected to be used to launch manned spacecraft in the future. This paper presents a general review of LM-7 with regard to the general scheme and provides references for the development prospects of a medium launch vehicle series in China. | WANG Xiaojun FAN Ruixiang CHENG Tangming XU Lijie YANG Haoliang | 2016 | Aerospace China2016，17，3： | 2 |
| 4 | Self-healing carrageenan-driven polyacrylamide hydrogels for strain sensing显示文摘Conductive hydrogels have attached considerable attention due to their good stretchability,excellent conductivity when they are applied in soft electronics. However,to fabricate a flexible hydrogel sensor with excellent toughness and good self-healing properties remains a challenge. In this work,we assembled a dual physical-crosslinking(DPC) ionic conductive polyacrylamide/carrageenan double-network(DN) hydrogel. This hydrogel has excellent fracture tensile stress and toughness,and demonstrates rapid self-recovery and self-healing ability due to the unique dual physical-crosslinking structures. Besides,the hydrogel is highly conductive by adding some conductive ions. As a result,the hydrogel-based sensor can stably detect human motions and physiological signals. The work provides novel ideas for the development of flexible sensing devices. | FAN ZiWen DUAN LiJie GAO GuangHui | 2020 | Science China(Technological Sciences)2020，63，12： | 2 |
| 5 | Osteogenic effects of antihypertensive drug benidipine on mouse MC3T3-E1 cells in vitro显示文摘Hypertension is a prevalent systemic disease in the elderly,who can suffer from several pathological skeletal conditions simultaneously,including osteoporosis.Benidipine(BD),which is widely used to treat hypertension,has been proved to have a beneficial effect on bone metabolism.In order to confirm the osteogenic effects of BD,we investigated its osteogenic function using mouse MC3T3-E1 preosteoblast cells in vitro.The proliferative ability of MC3T3-E1 cells was significantly associated with the concentration of BD,as measured by methylthiazolyldiphenyl-tetrazolium bromide(MTT)assay and cell cycle assay.With BD treatment,the osteogenic differentiation and maturation of MC3T3-E1 cells were increased,as established by the alkaline phosphatase(ALP)activity test,matrix mineralized nodules formation,osteogenic genetic test,and protein expression analyses.Moreover,our data showed that the BMP2/Smad pathway could be the partial mechanism for the promotion of osteogenesis by BD,while BD might suppress the possible function of osteoclasts through the OPG/RANKL/RANK(receptor activator of nuclear factor-κB(NF-κB))pathway.The hypothesis that BD bears a considerable potential in further research on its dual therapeutic effect on hypertensive patients with poor skeletal conditions was proved within the limitations of the present study. | Baixiang WANG Jiakang YANG Lijie FAN YuWANG Chenqiu ZHANG HuimingWANG | 2021 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2021，22，5： | 2 |

| 13 | Diffusion and Adsorption of Tetralin Hydrocracking Reaction on Different Zeolites by Molecular Simulation显示文摘Three different zeolite catalysts with different pore sizes(MFI-type,BEA-type,and FAU-type zeolites)have been prepared.The influence of different zeolite catalysts on reactivity and product shape selectivity of tetralin is investigated.Clear differences are observed in the reactivity of tetralin and distribution of products achieved by different catalysts.The diffusion and adsorption behavior of the reactant tetralin and its intermediates,n-butylbenzene and 1-methylindane under the reaction conditions are simulated using molecular simulation methods.Upon combining simulation results and experimental observations,it is shown that the difference in diffusion coefficient and competitive adsorption capacity can explain the reactivity of tetralin and the selectivity of products.The steric hindrance of the MFI-type zeolite mainly limits the key step of ring opening of tetralin,leading to lower selectivity of ring-opening products.n-Butylbenzene molecules can diffuse sufficiently fast in the large pores of FAU-type zeolite and the weak adsorption capacity of n-butylbenzene leads to its insufficient cracking.In addition,it also explains the reason that the BEA-type zeolite has the best BTX selectivity,because it can satisfy both good ring-opening activity and sufficient butylbenzene cracking depth. | Sun Lijie Fan Yaming Dong Songtao Xian Ce Long Xiangyun Li Dadong | 2021 | China Petroleum Processing & Petrochemical Technology2021，23，1： | 1 |
