| 1 | Chinese herbal medicine reduces mortality in patients with severe and critical coronavirus disease 2019: a retrospective cohort study显示文摘This study aimed to evaluate the efficacy of Chinese herbal medicine(CHM)in patients with severe/critical coronavirus disease 2019(COVID-19).In this retrospective study,data were collected from 662 patients with severe/critical COVID-19 who were admitted to a designated hospital to treat patients with severe COVID-19 in Wuhan before March 20,2020.All patients were divided into an exposed group(CHM users)and a control group(non-users).After propensity score matching in a 1:1 ratio,156 CHM users were matched by propensity score to 156 non-users.No significant differences in seven baseline clinical variables were found between the two groups of patients.All-cause mortality was reported in 13 CHM users who died and 36 non-users who died.After multivariate adjustment,the mortality risk of CHM users was reduced by 82.2%(odds ratio 0.178,95%CI 0.076–0.418;P<0.001)compared with the non-users.Secondly,age(odds ratio 1.053,95%CI 1.023–1.084;P<0.001)and the proportion of severe/critical patients(odds ratio 0.063,95%CI 0.028–0.143;P<0.001)were the risk factors of mortality.These results show that the use of CHM may reduce the mortality of patients with severe/critical COVID-19. | Guohua Chen Wen Su Jiayao Yang Dan Luo Ping Xia Wen Jia Xiuyang Li Chuan Wang Suping Lang Qingbin Meng Ying Zhang Yuhe Ke An Fan Shuo Yang Yujiao Zheng Xuepeng Fan Jie Qiao Fengmei Lian Li Wei Xiaolin Tong | 2020 | Frontiers of Medicine2020，14，6： | 10 |
| 2 | Source localization based on symmetrical MUSIC and its statistical performance analysis显示文摘In this paper,a new method for fast direction-of-arrival(DOA) estimation with no dependance on array configurations is proposed,which is referred to as the symmetrical multiple signal classification(SMUSIC).Unlike the standard MUSIC,the S-MUSIC spatial spectrum is constructed by the intersection of the noise subspace and the conjugate noise subspace,and it hence generates spectral peaks at the true DOAs and the symmetrical virtual DOAs simultaneously.Such a characteristic allows fast DOA estimation by spectral search over only half of the total angular filed-of-view.Therefore,the new approach has a much lower computational complexity than the standard MUSIC.The statistical performance of S-MUSIC is studied and a close-form expression for the MSEs(mean square errors) of DOA estimation by the proposed estimator is derived.Numerical simulations are conducted to demonstrate the effectiveness of the new algorithm and to verify the theoretical analysis,and it is indicated that S-MUSIC makes a trade-off between MSEs and lower computational complexity as well as an improved resolution for closely-spaced sources as compared to the standard MUSIC. | YAN FengGang JIN Ming QIAO XiaoLin | 2013 | Science China(Information Sciences)2013，56，6： | 9 |
| 3 | Preparation and Characterization of Nano-silver Loaded Montmorillonite with Strong Antibacterial Activity and Slow Release Property显示文摘Nano-silver loaded montmorillonite (Ag-MMT) was prepared by ion-exchange and then a UV-photoreduction two-step approach was applied. The silver content in Ag-MMT determined by Volhard method was about 6.4 wt%. The morphology and structure of as-synthesized Ag-MMT were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results showed that the Ag nanoparticles were spherical and their diameters were about 15-20 nm. Moreover, the structure of MMT did not change. The minimum inhibition concentration (MIC) of Ag-MMT was 100×10-6 and the sterilizing efficiency (SE) of Ag-MMT was approximately 100% against Escherichia coli ATCC 11229 (E. coli). In addition, the slow release property of silver in Ag-MMT was also demonstrated. | Guangnian Xu Xueliang Qiao Xiaolin Qiu Jianguo Chen | 2011 | Journal of Materials Science & Technology2011，27，8： | 4 |
| 4 | Microstructure induced galvanic corrosion evolution of SAC305 solder alloys in simulated marine atmosphere显示文摘Motivated by the increasing use of Sn-3.0 Ag-0.5 Cu(SAC305)solder in electronics worked in marine atmospheric environment and the uneven distribution of Ag3Sn and Cu6Sn5 intermetallic compounds(IMCs)inβ-Sn matrix,comb-like electrodes have been designed for in-situ EIS measurements to study the microstructure induced galvanic corrosion evolution of SAC305 solder in simulated marine atmosphere with high-temperature and high-humidity.Results indicate that in-situ EIS measurement by comb-like electrodes is an effective method for corrosion evolution behavior study of SAC305 solder.Besides,the galvanic effect between Ag3Sn IMCs andβ-Sn matrix can aggravate the corrosion of both as-received and furnace-cooled SAC305 solder as the exposure time proceeds in spite of the presence of corrosion product layer.Pitting corrosion can be preferentially found on furnace-cooled SAC305 with larger Ag3Sn grain size.Moreover,the generated inner stress during phases transformation process with Sn3O(OH)2Cl2 as an intermediate and the possible hydrogen evolution at local acidified sites are supposed to be responsible for the loose,porous,cracked,and non-adherent corrosion product layer.These findings clearly demonstrate the corrosion acceleration behavior and mechanism of SAC305 solder,and provide potential guidelines on maintenance of microelectronic devices for safe operation and longer in-service duration. | Mingna Wang Chuang Qiao Xiaolin Jiang Long Hao Xiahe Liu | 2020 | Journal of Materials Science & Technology2020，47，16： | 4 |
| 5 | Cloning of Porcine Lactoferrin Gene and Construction of Expression System in Recombinant Lactobacillus显示文摘Lactobacillus was selected as a bacterial carrier for expression of N-lobe of porcine lactoferrin(PLF N) . A pair of primers was designed with Oligo6.0 and used to amplify PLF N gene. It was in accordance with the characters of translational fusions from gene and expression vector plasmid. A 1 077 bp fragment of the gene from PLF was cloned from mammary gland tissue of the lactating sow on the third day by RT-PCR;the gene was connected with the vector plasmid pPG612.1 and transformed into the host strain JM109. The recombinant expression vector plasmid pPG612-PLF N was created and identified by using plasmid extraction,PCR,restriction enzyme digestion and sequence analysis. The recombinant plasmid was transformed into Lactobacillus casei ATCC393,Lactobacillus plantarum KLDS 1.0344,Lactobacillus paracasei KLDS 1.0652 and Lactobacillus pentosus KLDS1.0413 by electroporation,and produced the recombinant strains of pPG612-PLF N /L. casei,pPG612-PLF N /L. plantarum,pPG612-PLF N /L. paracasei and pPG612-PLF N /L. pentosus,respectively. The results indicated that PLF N gene had inserted into the expression vectors and achieved multiple Lactobacillus expression systems. It electes the base for the expression and production of recombinant porcine lactoferrin in Lactobacillus. | ZONG Xiaolin HA Zhuo ZHAO Lili LIU Diqiu QIAO Xinyuan JIANG Yanping GE Junwei LI Yijing TANG Lijie | 2011 | Journal of Northeast Agricultural University(English Edition)2011，18，4： | 3 |
| 6 | Temperature and NaCl deposition dependent corrosion of SAC305 solder alloy in simulated marine atmosphere显示文摘The stable operation of electronic devices in marine atmospheric environment is affected by the corrosion deterioration of solder joints,and the effects by atmosphere temperature and chloride deposition are critical.In this work,NaCl deposition and temperature dependent corrosion of Pb-free SAC305 solder in simulated marine atmosphere has been investigated.The results indicate that higher NaCl deposition prolongs the surface wetting time and leads to the final thicker saturated electrolyte film for further corrosion.Higher temperature accelerates the evaporation and contributes to the final thinner saturated NaCl electrolyte film.Besides,the corrosion control process varies under the initially covered thicker NaCl electrolyte layer and under the final saturated much thinner NaCl electrolyte film as the evaporation proceeds.Moreover,the ready oxygen availability through the final thinner saturated NaCl electrolyte film facilitates the formation of corrosion product layer mainly of electrochemically stable SnO2,but higher temperature leads to the final corrosion product layer with smaller crystal size and large cracks.The findings clearly demonstrate the effects of NaCl deposition and temperature on corrosion evolution of SAC305 solder joints and are critical to the daily maintenance of electronic devices for longer service life in marine atmosphere. | Chuang Qiao Mingna Wang Long Hao Xiahe Liu Xiaolin Jiang Xizhong An Duanyang Li | 2021 | Journal of Materials Science & Technology2021，，16： | 3 |
| 7 | Computationally efficient direction finding using polynomial rooting with reduced-order and real-valued computations显示文摘The root multiple signal classification(root-MUSIC) algorithm is one of the most important techniques for direction of arrival(DOA) estimation. Using a uniform linear array(ULA) composed of M sensors, this method usually estimates L signal DOAs by finding roots that lie closest to the unit circle of a(2M-1)-order polynomial, where L < M. A novel efficient root-MUSIC-based method for direction estimation is presented, in which the order of polynomial is efficiently reduced to 2L. Compared with the unitary root-MUSIC(U-root-MUSIC) approach which involves real-valued computations only in the subspace decomposition stage, both tasks of subspace decomposition and polynomial rooting are implemented with real-valued computations in the new technique,which hence shows a significant efficiency advantage over most state-of-the-art techniques. Numerical simulations are conducted to verify the correctness and efficiency of the new estimator. | Fenggang Yan Yi Shen Ming Jin Xiaolin Qiao | 2016 | Journal of Systems Engineering and Electronics2016，27，4： | 3 |

| 9 | Joint DOA and polarization estimation for unequal power sources based on reconstructed noise subspace显示文摘In most literature about joint direction of arrival(DOA) and polarization estimation, the case that sources possess different power levels is seldom discussed. However, this case exists widely in practical applications, especially in passive radar systems. In this paper, we propose a joint DOA and polarization estimation method for unequal power sources based on the reconstructed noise subspace. The invariance property of noise subspace(IPNS) to power of sources has been proved an effective method to estimate DOA of unequal power sources. We develop the IPNS method for joint DOA and polarization estimation based on a dual polarized array. Moreover, we propose an improved IPNS method based on the reconstructed noise subspace, which has higher resolution probability than the IPNS method. It is theoretically proved that the IPNS to power of sources is still valid when the eigenvalues of the noise subspace are changed artificially. Simulation results show that the resolution probability of the proposed method is enhanced compared with the methods based on the IPNS and the polarimetric multiple signal classification(MUSIC) method. Meanwhile, the proposed method has approximately the same estimation accuracy as the IPNS method for the weak source. | Yong Han Qingyuan Fang Fenggang Yan Ming Jin Xiaolin Qiao | 2016 | Journal of Systems Engineering and Electronics2016，27，3： | 2 |
| 10 | Signal processing method of a novel polarized array radar seeker显示文摘This paper proposes a novel polarized radar seeker based on the polarized antenna array. A fully polarized signal processing method for the proposed radar seeker is studied under the environments with electromagnetic interferences. A dual polarized antenna array is employed to transmit and receive the radar signals. The instantaneous polarization signal processing technique is used to detect and recognize the targets. The direction of arrival(DOA) of the target is measured through the spatial spectrum with high resolution for the polarized array radar seeker system. The fully polarized signal model of the polarized array radar seeker is formulated and a specific signal processing algorithm is expounded. The theoretical research and numerical simulation results demonstrate that the proposed radar seeker has good performances in target detection and electronic warfare. The research results can provide an effective technical approach to develop and research the new generation radar seeker. | Lizhong Song Xiaolin Qiao | 2013 | Journal of Systems Engineering and Electronics2013，24，5： | 1 |
| 11 | Scheme of adaptive polarization filtering based on Kalman model显示文摘A new kind of adaptive polarization filtering algorithm in order to suppress the angle cheating interference for the active guidance radar is presented. The polarization characteristic of the interference is dynamically tracked by using Kalman estimator under variable environments with time. The polarization filter parameters are designed according to the polarization characteristic of the interference, and the polarization filtering is finished in the target cell. The system scheme of adaptive polarization filter is studied and the tracking performance of polarization filter and improvement of angle measurement precision are simulated. The research results demonstrate this technology can effectively suppress the angle cheating interference in guidance radar and is feasible in engineering. | Song Lizhong Qi Haiming Qiao Xiaolin Meng Xiande | 2006 | Journal of Systems Engineering and Electronics2006，17，1： | 1 |
| 12 | An adaptive cell-based domain integration method for treatment of domain integrals in 3D boundary element method for potential and elasticity problems显示文摘An adaptive cell-based domain integration method(CDIM) is proposed for the treatment of domain integrals in 3D boundary element method(BEM). The domain integrals are computed in background cells rather than volume elements. The cells are created from the boundary elements based on an adaptive oct-tree structure and no other discretization is needed. Cells containing the boundary elements are subdivided into smaller sub-cells adaptively according to the sizes and levels of the boundary elements; and the sub-cells outside the domain are deleted to obtain the desired accuracy. The method is applied in the 3D potential and elasticity problems in this paper. | Qiao Wang Wei Zhou Yonggang Cheng Gang Ma Xiaolin Chang Qiang Huang | 2017 | Acta Mechanica Solida Sinica2017，30，1： | 1 |
| 13 | Knowledge-based adaptive polarimetric detection in heterogeneous clutter显示文摘The detection performance and the constant false alarm rate behavior of the conventional adaptive detectors are severely degraded in heterogeneous clutter. This paper designs and analyses a knowledge-based(KB) adaptive polarimetric detector in heterogeneous clutter. The proposed detection scheme is composed of a data selector using polarization knowledge and an adaptive polarization detector using training data. A polarization data selector based on the maximum likelihood estimation is proposed to remove outliers from the heterogeneous training data. This selector can remove outliers effectively, thus the training data is purified for estimating the clutter covariance matrix. Consequently,the performance of the adaptive detector is improved. We assess the performance of the KB adaptive polarimetric detector and the adaptive polarimetric detector without a data selector using simulated data and IPIX radar data. The results show that the KB adaptive polarization detector outperforms its non-KB counterparts. | Yinan Zhao Fengcong Li Xiaolin Qiao | 2014 | Journal of Systems Engineering and Electronics2014，25，3： | 1 |
