| 1 | Factors Affecting Sensory Quality of Cooked japonica Rice显示文摘The sensory quality of cooked rice is an important factor in determining its market price, as well as consumer acceptance and breeding efforts aimed at improvement of rice grain quality. In this study,the sensory quality and physicochemical properties of three japonica rice varieties harvested in two different growing locations(Xiangshui and Hangzhou of China) were compared to determine the most important factors affecting the sensory quality. All the three varieties had higher scores for overall sensory quality in Xiangshui than in Hangzhou, indicating that the growing location is a key factor in determining the sensory quality of cooked japonica rice. In addition to growing location, variety(genotype) also had an important effect. Longdao 18 scored the highest for overall sensory quality in the two locations, whereas Longdao 30 had the lowest score in Xiangshui, and both Longdao 20 and Longdao 30 had the lowest scores in Hangzhou. Many physicochemical properties, such as apparent amylose content, protein content, thermal properties and free amino acid contents, showed significant differences between the two locations. Correlation analysis showed that apparent amylose content and protein content had contrasting effects on all the sensory attributes. The overall sensory quality was negatively correlated with protein content(r =-0.89, P < 0.01) and positively correlated with gel hardness(r = 0.91, P < 0.01),indicating that the protein content and hardness are important physicochemical properties for predicting the sensory quality of japonica rice. These findings will provide guidance for selection from the diverse genotypes available to develop new varieties with the desired eating and cooking quality. | XU Yanjie YING Yining OUYANG Shuhong DUAN Xiaoliang SUN Hui JIANG Shukun SUN Shichen BAO Jinsong | 2018 | Rice science2018，25，6： | 23 |
| 2 | Robust adaptive fault-tolerant control of a tandem coaxial ducted fan aircraft with actuator saturation显示文摘This paper is concerned with the robust adaptive fault-tolerant control of a tandem coaxial ducted fan aircraft under system uncertainty, mismatched disturbance, and actuator saturation.For the proposed aircraft, comprehensive controllability analysis is performed to evaluate the controllability of each state as well as the margin to reject mismatched disturbance without any knowledge of the controller. Mismatched disturbance attenuation is ensured through a structured Hinfinity controller tuned by a non-smooth optimization algorithm. Embedded with the H-infinity controller, an adaptive control law is proposed in order to mitigate matched system uncertainty and actuator fault. Input saturation is also considered by the modified reference model. Numerical simulation of the novel ducted fan aircraft is provided to illustrate the effectiveness of the proposed method. The simulation results reveal that the proposed adaptive controller achieves better transient response and more robust performance than classic Model Reference Adaptive Control(MRAC) method, even with serious actuator saturation. | Xiaoliang WANG Changle XIANG Homayoun NAJJARAN Bin XU | 2018 | Chinese Journal of Aeronautics2018，31，6： | 14 |
| 3 | Humoral immune response to circulating SARS-CoV-2 variants elicited by inactivated and RBD-subunit vaccines显示文摘SARS-CoV-2 variants could induce immune escape by mutations on the receptor-binding domain(RBD)and N-terminal domain(NTD).Here we report the humoral immune response to circulating SARS-CoV-2 variants,such as 501Y.V2(B.1.351),of the plasma and neutralizing antibodies(NAbs)elicited by CoronaVac(inactivated vaccine),ZF2001(RBD-subunit vaccine)and natural infection.Among 86 potent NAbs identified by high-throughput single-cell VDJ sequencing of peripheral blood mononuclear cells from vaccinees and convalescents,near half anti-RBD NAbs showed major neutralization reductions against the K417N/E484K/N501Y mutation combination,with E484K being the dominant cause.VH3-53/VH3-66 recurrent antibodies respond differently to RBD variants,and K417N compromises the majority of neutralizing activity through reduced polar contacts with complementarity determining regions.In contrast,the 242–244 deletion(242–244Δ)would abolish most neutralization activity of anti-NTD NAbs by interrupting the conformation of NTD antigenic supersite,indicating a much less diversity of anti-NTD NAbs than anti-RBD NAbs.Plasma of convalescents and CoronaVac vaccinees displayed comparable neutralization reductions against pseudo-and authentic 501Y.V2 variants,mainly caused by E484K/N501Y and 242–244Δ,with the effects being additive.Importantly,RBD-subunit vaccinees exhibit markedly higher tolerance to 501Y.V2 than convalescents,since the elicited anti-RBD NAbs display a high diversity and are unaffected by NTD mutations.Moreover,an extended gap between the third and second doses of ZF2001 leads to better neutralizing activity and tolerance to 501Y.V2 than the standard three-dose administration.Together,these results suggest that the deployment of RBD-vaccines,through a third-dose boost,may be ideal for combating SARS-CoV-2 variants when necessary,especially for those carrying mutations that disrupt the NTD supersite. | Yunlong Cao Ayijiang Yisimayi Yali Bai Weijin Huang Xiaofeng Li Zhiying Zhang Tianjiao Yuan Ran An Jing Wang Tianhe Xiao Shuo Du Wenping Ma Liyang Song Yongzheng Li Xiang Li Weiliang Song Jiajing Wu Shuo Liu Xuemei Li Yonghong Zhang Bin Su Xianghua Guo Yangyang Wei Chuanping Gao Nana Zhang Yifei Zhang Yang Dou Xiaoyu Xu Rui Shi Bai Lu Ronghua Jin Yingmin Ma Chengfeng Qin Youchun Wang Yingmei Feng Junyu Xiao Xiaoliang Sunney Xie | 2021 | Cell Research2021，31，7： | 12 |
| 4 | Adsorption separation of carbon dioxide, methane and nitrogen on monoethanol amine modified β-zeolite显示文摘A new type of composite adsorbents was synthesized by incorporating monoethanol amine (MEA) into β-zeolite. The parent and MEA- functionalized β-zeolites were characterized by X-ray diffraction (XRD), N2 adsorption, and thermogravimetric analysis (TGA). The adsorption behavior of carbon dioxide (CO2), methane (CH4), and nitrogen (N2) on these adsorbents was investigated at 303 K. The results show that the structure of zeolite was well preserved after MEA modification. In comparison with CH4 and N2, CO2 was preferentially adsorbed on the adsorbents investigated. The introduction of MEA significantly improved the selectivity of both CO2/CH4 and CO2/N2, the optimal selectivity of CO2/CH4 can reach 7.70 on 40 wt% of MEA-functionalized β-zeolite (MEA(40)-β) at 1 atm. It is worth noticing that a very high selectivity of CO2/N2 of 25.67 was obtained on MEA(40)-β. Steric effect and chemical adsorbate-adsorbent interaction were responsible for such high adsorption selectivity of CO2. The present MEA-functionalized β-zeolite adsorbents may be a good candidate for applications in flue gas separation, as well as natural gas and landfill gas purifications. | Xiaoliang Xu Xingxiang Zhao Linbing Sun Xiaoqin Liu | 2009 | Journal of Natural Gas Chemistry2009，18，2： | 11 |

| 6 | Longitudinal non-vascular transport pathways originating from acupuncture points in extremities visualised in human body显示文摘A subcutaneous transport pathway in humans has been previously visualised by injection of a paramagnetic tracer into the specific region of skin.In the current study,we further investigated the behaviours of imaging tracers in the transport pathways using imaging techniques.Three types of imaging tracers,including Gd-DTPA,iodised oil,and fluorescein sodium,were hypodermically injected into different acupuncture points of healthy volunteers to visualise the transport pathways by magnetic resonance imaging(MRI),X-ray,CT,and a digital fluorescein camera.Several longitudinal transport pathways in the arms and feet,which represent venous vessels and subcutaneous transport pathways(STPs) without well-defined boundaries,were visualised by MRI.Among the visualised veins,the partial walls of a few veins were enhanced by Gd-DTPA.The fluorescent images further indicated that STPs likely represent boundless pathways.The findings in this study suggested that specific anatomical structures within the subcutaneous tissues or the partial walls of certain veins werenot vascular conduits but rather represented unique transport pathways in humans that warrant extensive future studies. | Hongyi Li Jiabin Tong Weiguo Cao Min Chen Hua Li Hong Dai Liang Xu Xiaoliang Chen | 2014 | Chinese Science Bulletin2014，59，35： | 10 |

| 9 | Crosstalk-free achromatic full Stokes imaging polarimetry metasurface enabled by polarization-dependent phase optimization显示文摘Imaging polarimetry is one of the most widely used analytical technologies for object detection and analysis.To date,most metasurface-based polarimetry techniques are severely limited by narrow operating bandwidths and inevitable crosstalk,leading to detrimental effects on imaging quality and measurement accuracy.Here,we propose a crosstalkfree broadband achromatic full Stokes imaging polarimeter consisting of polarization-sensitive dielectric metalenses,implemented by the principle of polarization-dependent phase optimization.Compared with the single-polarization optimization method,the average crosstalk has been reduced over three times under incident light with arbitrary polarization ranging from 9μm to 12μm,which guarantees the measurement of the polarization state more precisely.The experimental results indicate that the designed polarization-sensitive metalenses can effectively eliminate the chromatic aberration with polarization selectivity and negligible crosstalk.The measured average relative errors are 7.08%,8.62%,7.15%,and 7.59%at 9.3,9.6,10.3,and 10.6μm,respectively.Simultaneously,the broadband full polarization imaging capability of the device is also verified.This work is expected to have potential applications in wavefront detection,remote sensing,light-field imaging,and so forth. | Yaxin Zhang Mingbo Pu Jinjin Jin Xinjian Lu Yinghui Guo Jixiang Cai Fei Zhang Yingli Ha Qiong He Mingfeng Xu Xiong Li Xiaoliang Ma Xiangang Luo | 2022 | Opto-Electronic Advances2022，5，11： | 6 |
| 10 | Phthalide-derived oxaspiroangelioic acids A–C with an unprecedented carbon skeleton from an aqueous extract of the Angelica sinensis root head显示文摘Three phthalide-derived analogues,oxaspiroangelioic acids A–C(1–3),were isolated as minor components of an aqueous extract of the Angelica sinensis root heads(guitou).Oxaspiroangelioic acids A and B were racemates separated into enantiomers by chiral HPLC.Their structures including absolute configurations were determined by spectroscopic data analysis,single crystal X-ray diffraction,exciton chirality method [7_(T)D$IF]and electronic circular dichroism(ECD) calculation.These compounds share an undescribed carbon skeleton,for which biosynthetic pathways are proposed.Compound 1 and its enantiomers showed almost identical activity inhibiting Tandem of P domains in a weak inwardly rectifying K^(+)channel 1(TREK-1). | Youzhe Chen Chengbo Xu Weiping Wang Xiaoliang Wang Qinglan Guo Jiangong Shi | 2021 | Chinese Chemical Letters2021，32，10： | 6 |
| 11 | Sand flux estimation during a sand-dust storm at Tazhong area of Taklimakan Desert, China显示文摘In this paper, the sand transport during a sand-dust storm in the Tazhong area of the central Taklimakan Desert from 11:29 to 23:56 on July 19, 2008 was observed and measured in real time. The sand flux at Tazhong was estimated using sand transport empirical formulas. The critical friction velocity at Tazhong was 0.24 m/s and the functional relation between the wind speed and sediment discharge at the height of 2 m was established. It was also found that the calculated values by Lettau's sediment discharge formula were close to those of the instrument measurements. The horizontal sand flux and the vertical sand flux during this sand-dust storm at Tazhong were respectively 258.67×10-4 kg/(m·s) and 40.07×10-7 kg/(m2·s). | XingHua YANG XiaoLiang XU Qing HE Ali Mamtimin Bo YU ShiHao TANG | 2011 | Journal of Arid Land2011，3，3： | 6 |
| 12 | Discrimination for ablative control mechanism in solid-propellant rocket nozzle显示文摘The ablation in solid-propellant rocket nozzle is a coupling process resulted by chemistry, heat and mass transfer. Based on the heat and mass transfer theory, the aero-thermo-dynamic, and thermo-chemical kinetics, the thermal-chemical ablation model is established. Simulations are completed on the heat flow field and chemical ablation in the nozzle with different concentrations, frequency factors and activation energy of H2. The calculation results show that the concentration and the activation energy of H2 can provoke the transformation of control mechanism, whereas the influence brought by the frequency factor of H2 is feeble under a high-temperature and high-pressure combustion circumstance. The discrimination for ablative control mechanism is dependent on both concentration and activation energy of H2. This study will be useful in handling ablation and thermal protection problem in the design of solid-propellant rocket. | HUANG HaiMing XU XiaoLiang JIANG GuiQing | 2009 | Science China(Technological Sciences)2009，52，10： | 6 |

| 14 | Insulating materials for realising carbon neutrality:Opportunities,remaining issues and challenges显示文摘The 2050 carbon-neutral vision spawns a novel energy structure revolution,and the construction of the future energy structure is based on equipment innovation.Insulating material,as the core of electrical power equipment and electrified transportation asset,faces unprecedented challenges and opportunities.The goal of carbon neutral and the urgent need for innovation in electric power equipment and electrification assets are first discussed.The engineering challenges constrained by the insulation system in future electric power equipment/devices and electrified transportation assets are investigated.Insulating materials,including intelligent insulating material,high thermal conductivity insulating material,high energy storage density insulating material,extreme environment resistant insulating material,and environmental-friendly insulating material,are cat-egorised with their scientific issues,opportunities and challenges under the goal of carbon neutrality being discussed.In the context of carbon neutrality,not only improves the understanding of the insulation problems from a macro level,that is,electrical power equipment and electrified transportation asset,but also offers opportunities,remaining issues and challenges from the insulating material level.It is hoped that this paper en-visions the challenges regarding design and reliability of insulations in electrical equipment and electric vehicles in the context of policies towards carbon neutrality rules.The authors also hope that this paper can be helpful in future development and research of novel insulating materials,which promote the realisation of the carbon-neutral vision. | Chuanyang Li Yang Yang Guoqiang Xu Yao Zhou Mengshuo Jia Shaolong Zhong Yu Gao Chanyeop Park Qiang Liu Yalin Wang Shakeel Akram Xiaoliang Zeng Yi Li Fangwei Liang Bin Cui Junpeng Fang Lingling Tang Yulin Zeng Xingtao Hu Jiachen Gao Giovanni Mazzanti Jinliang He Jianxiao Wang Davide Fabiani Gilbert Teyssedre Yang Cao Feipeng Wang Yunlong Zi | 2022 | High Voltage2022，7，4： | 4 |
| 15 | Control of Aggregate Size of Polyethyleneimine-Coated Magnetic Nanoparticles for Magnetofection显示文摘Using magnetic nanoparticles to enhance gene transfection,a recently developed technique termed magnetofection,has been shown to be a powerful technology in gene delivery.The most widely used magnetic nanoparticles in this area are those coated with polyethyleneimine,which is a well known non-viral transfection agent.In this article,we report methods to control the aggregate size of polyethyleneimine-coated magnetite particles.These particles were then used to enhance transfection of green fluorescent protein(GFP)into NIH 3T3 cells in vitro.We find that the aggregate size of the particles has a great effect on their performance in magnetofection,with less aggregated magnetic particles being more effective in enhancing the gene transfection. | Xiaoliang Wang Linzhu Zhou Yongjie Ma Xu Li Hongchen Gu | 2009 | Nano Research2009，2，5： | 4 |
| 16 | Brain-derived neurotrophic factor inhibits glucose intolerance after cerebral ischemia显示文摘Brain-derived neurotrophic factor is associated with the insulin signaling pathway and glucose metabolism.We hypothesized that expression of brain-derived neurotrophic factor and its receptor may be involved in glucose intolerance following ischemic stress.To verify this hypothesis,this study aimed to observe the changes in brain-derived neurotrophic factor and tyrosine kinase B receptor expression in glucose metabolism-associated regions following cerebral ischemic stress in mice.At day 1 after middle cerebral artery occlusion,the expression levels of brain-derived neurotrophic factor were significantly decreased in the ischemic cortex,hypothalamus,liver,skeleta muscle,and pancreas.The expression levels of tyrosine kinase B receptor were decreased in the hypothalamus and liver,and increased in the skeletal muscle and pancreas,but remained unchanged in the cortex.Intrahypothalamic administration of brain-derived neurotrophic factor(40ng)suppressed the decrease in insulin receptor and tyrosine-phosphorylated insulin receptor expression in the liver and skeletal muscle,and inhibited the overexpression of gluconeogenesis-associated phosphoenolpyruvate carboxykinase and glucose-6-phosphatase in the liver of cerebral ischemic mice.However,serum insulin levels remained unchanged.Our experimental findings indicate that brain-derived neurotrophic factor can promote glucose metabolism,reduce gluconeogenesis,and decrease blood glucose levels after cerebral ischemic stress.The low expression of brain-derived neurotrophic factor following cerebral ischemia may be involved in the development of glucose intolerance. | Xiaoliang Shu Yongsheng Zhang Han Xu Kai Kang Donglian Cai | 2013 | Neural Regeneration Research2013，8，25： | 3 |
| 17 | Electroacupuncture relieves irritable bowel syndrome by increasing expression of nucleotide-binding oligomerization domain protein-like receptor family pyrin domain containing 6 in water-avoidance stress mice显示文摘OBJECTIVE: To investigate the effect of electroacupuncture(EA) on irritable bowel syndrome(IBS) in mice through regulating nucleotide-binding oligomerization domain protein-like receptor family pyrin domain containing 6(NLRP6).METHODS: Water-avoidance stress(WAS) mice model was used to investigate the effects and the mechanism of EA. Abdominal withdrawal reflex test, open field test, and intestinal motility test were used to evaluate visceral sensitivity, anxiety,and intestinal motility in mice. The expressions of NLRP6, Mucin-2(MUC2) and E-cadherin were determined using immunofluorescence and Western blotting assays.RESULTS: EA significantly upregulated the expression of NLRP6 in the intestine of mice. Moreover, EA increased the expressions of MUC2 and E-cadherin in WAS mice.CONCLUSION: Our study found that the relief of IBS symptoms by EA may involve the increase in the expression of NLRP6 in WAS mice. | Song Yafang Geng Hao Chen Lu Wu Xiaoliang Yuan Mengqian Xu Wanli Guo Jing Sun Jianhua Pei Lixia | 2020 | Journal of Traditional Chinese Medicine2020，40，3： | 3 |
| 18 | Event Temporal Relation Extraction with Attention Mechanism and Graph Neural Network显示文摘Event temporal relation extraction is an important part of natural language processing.Many models are being used in this task with the development of deep learning.However,most of the existing methods cannot accurately obtain the degree of association between different tokens and events,and event-related information cannot be effectively integrated.In this paper,we propose an event information integration model that integrates event information through multilayer bidirectional long short-term memory(Bi-LSTM)and attention mechanism.Although the above scheme can improve the extraction performance,it can still be further optimized.To further improve the performance of the previous scheme,we propose a novel relational graph attention network that incorporates edge attributes.In this approach,we first build a semantic dependency graph through dependency parsing,model a semantic graph that considers the edges’attributes by using top-k attention mechanisms to learn hidden semantic contextual representations,and finally predict event temporal relations.We evaluate proposed models on the TimeBank-Dense dataset.Compared to previous baselines,the Micro-F1 scores obtained by our models improve by 3.9%and 14.5%,respectively. | Xiaoliang Xu Tong Gao Yuxiang Wang Xinle Xuan | 2022 | Tsinghua Science and Technology2022，27，1： | 2 |
| 19 | Potassium 2-(1-hydroxypentyl)-benzoate improves depressive-like behaviors in rat model显示文摘Potassium 2-(1-hydroxypentyl)-benzoate(PHPB) is a novel drug candidate for acute ischemic stroke. PHPB has been also shown to be beneficial for some neurodegenerative diseases. In this study, we demonstrated that PHPB improved depressive-like behaviors induced by chronic unpredictable mild stress(CUMS) in rats. Male SD rats were subjected to the stress for five weeks. PHPB(30 and 100 mg/kg) or fluoxetine(FLX 10 mg/kg, as positive control) was administered orally from the third week in CUMS procedure. The behavioral tests were applied and then the biochemical studies were carried out. PHPB or FLX treatment rescued the behavioral deficiency in CUMS-exposed rats. Meanwhile, PHPB normalized the enhanced level of serum corticosterone, improved hippocampal and serum BDNF levels, as well as p-CREB level in hippocampus. In addition, PHPB could reverse the reduced level of extracellular 5-HT and its metabolite 5-HIAA in prefrontal cortex(PFC) of depressed rats. In summary, our results showed that PHPB improved depression-like behaviors in CUMS-exposed rats. The mechanisms might relate to the reverse of neurotrophic disturbance in the brain, reducing excessive HPA axis response and facilitating the release of 5-HT. | Hao Ma Weiping Wang Shaofeng Xu Ling Wang Xiaoliang Wang | 2018 | Acta Pharmaceutica Sinica B2018，8，6： | 2 |
| 20 | Image recognition and empirical application of desert plant species based on convolutional neural network显示文摘In recent years,deep convolution neural network has exhibited excellent performance in computer vision and has a far-reaching impact.Traditional plant taxonomic identification requires high expertise,which is time-consuming.Most nature reserves have problems such as incomplete species surveys,inaccurate taxonomic identification,and untimely updating of status data.Simple and accurate recognition of plant images can be achieved by applying convolutional neural network technology to explore the best network model.Taking 24 typical desert plant species that are widely distributed in the nature reserves in Xinjiang Uygur Autonomous Region of China as the research objects,this study established an image database and select the optimal network model for the image recognition of desert plant species to provide decision support for fine management in the nature reserves in Xinjiang,such as species investigation and monitoring,by using deep learning.Since desert plant species were not included in the public dataset,the images used in this study were mainly obtained through field shooting and downloaded from the Plant Photo Bank of China(PPBC).After the sorting process and statistical analysis,a total of 2331 plant images were finally collected(2071 images from field collection and 260 images from the PPBC),including 24 plant species belonging to 14 families and 22 genera.A large number of numerical experiments were also carried out to compare a series of 37 convolutional neural network models with good performance,from different perspectives,to find the optimal network model that is most suitable for the image recognition of desert plant species in Xinjiang.The results revealed 24 models with a recognition Accuracy,of greater than 70.000%.Among which,Residual Network X_8GF(RegNetX_8GF)performs the best,with Accuracy,Precision,Recall,and F1(which refers to the harmonic mean of the Precision and Recall values)values of 78.33%,77.65%,69.55%,and 71.26%,respectively.Considering the demand factors of hardware equipment and inference time,Mobile NetworkV2 achieves the best balance among the Accuracy,the number of parameters and the number of floating-point operations.The number of parameters for Mobile Network V2(MobileNetV2)is 1/16 of RegNetX_8GF,and the number of floating-point operations is 1/24.Our findings can facilitate efficient decision-making for the management of species survey,cataloging,inspection,and monitoring in the nature reserves in Xinjiang,providing a scientific basis for the protection and utilization of natural plant resources. | LI Jicai SUN Shiding JIANG Haoran TIAN Yingjie XU Xiaoliang | 2022 | Journal of Arid Land2022，14，12： | 2 |
