| 2 | A Text Sentiment Classification Modeling Method Based on Coordinated CNN-LSTM-Attention Model显示文摘The major challenge that text sentiment classification modeling faces is how to capture the intrinsic semantic, emotional dependence information and the key part of the emotional expression of text. To solve this problem, we proposed a Coordinated CNNLSTM-Attention(CCLA) model. We learned the vector representations of sentence with CCLA unit. Semantic and emotional information of sentences and their relations are adaptively encoded to vector representations of document.We used softmax regression classifier to identify the sentiment tendencies in the text. Compared with other methods, the CCLA model can well capture the local and long distance semantic and emotional information.Experimental results demonstrated the effectiveness of CCLA model. It shows superior performances over several state-of-the-art baseline methods. | ZHANG Yangsen ZHENG Jia JIANG Yuru HUANG Gaijuan CHEN Ruoyu | 2019 | Chinese Journal of Electronics2019，28，1： | 32 |
| 3 | Development of a Hand Exoskeleton System for Index Finger Rehabilitation显示文摘In order to overcome the drawbacks of traditional rehabilitation method,the robot-aided rehabilitation has been widely investigated for the recent years.And the hand rehabilitation robot,as one of the hot research fields,remains many challenging issues to be investigated.This paper presents a new hand exoskeleton system with some novel characteristics.Firstly,both active and passive rehabilitative motions are realized.Secondly,the device is elaborately designed and brings advantages in many aspects.For example,joint motion is accomplished by a parallelogram mechanism and high level motion control is therefore made very simple without the need of complicated kinematics.The adjustable joint limit design ensures that the actual joint angles don't exceed the joint range of motion(ROM) and thus the patient safety is guaranteed.This design can fit to the different patients with different joint ROM as well as to the dynamically changing ROM for individual patient.The device can also accommodate to some extent variety of hand sizes.Thirdly,the proposed control strategy simultaneously realizes the position control and force control with the motor driver which only works in force control mode.Meanwhile,the system resistance compensation is preliminary realized and the resisting force is effectively reduced.Some experiments were conducted to verify the proposed system.Experimentally collected data show that the achieved ROM is close to that of a healthy hand and the range of phalange length(ROPL) covers the size of a typical hand,satisfying the size need of regular hand rehabilitation.In order to evaluate the performance when it works as a haptic device in active mode,the equivalent moment of inertia(MOI) of the device was calculated.The results prove that the device has low inertia which is critical in order to obtain good backdrivability.The experiments also show that in the active mode the virtual interactive force is successfully feedback to the finger and the resistance is reduced by one-third;for the passive control mode,the desired trajectory is realized satisfactorily. | LI Jiting WANG Shuang WANG Ju ZHENG Ruoyin ZHANG Yuru CHEN Zhongyuan | 2012 | Chinese Journal of Mechanical Engineering2012，25，2： | 12 |
| 4 | Comparing containment measures among nations by epidemiological effects of COVID-19显示文摘The coronavirus disease 2019(COVID-19)has evolved to a global pandemic since its inception in December 2019.Countries have responded to the epidemics with different levels of responses and containment measures.Given the unprecedented pressure on nations’healthcare systems and the deaths so far,there is an urgent need to evaluate the effects of the containm ent measures,which would be useful for countries to plan for their responses to counter the first or possibly the second wave of the epidemic.There have been studies for the effects of COVID-19 control measures taken in China on disease transmission and public health interventions for W uhan’s outbreaks[1-4],and W uhan travel ban on the spread of COVID-19 both inside China and internationally[5,6]. | Jia Gu Han Yan Yaxuan Huang Yuru Zhu Haoxuan Sun Yumou Qiu Songxi Chen | 2020 | National Science Review2020，7，12： | 4 |
| 5 | Phosphatase activity and culture conditions of the yeast Candida mycoderma sp. and analysis of organic phosphorus hydrolysis ability显示文摘Orthophosphate is an essential but limiting macronutrient for plant growth. About 67%cropland in China lacks sufficient phosphorus, especially that with red soil. Extensive soil phosphorus reserves exist in the form of organic phosphorus, which is unavailable for root uptake unless hydrolyzed by secretory acid phosphatases. Thus, many microorganisms with the ability to produce phosphatase have been exploited. In this work, the activity of an extracellular acid phosphatase and yeast biomass from Candida mycoderma was measured under different culture conditions, such as p H, temperature, and carbon source. A maximal phosphatase activity of 8.47 × 105± 0.11 × 105U/g was achieved by C. Mycoderma in 36 hr under the optimal conditions. The extracellular acid phosphatase has high activity over a wide p H tolerance range from 2.5 to 5.0(optimum p H 3.5). The effects of different phosphorus compounds on the acid phosphatase production were also studied. The presence of phytin, lecithin or calcium phosphate reduced the phosphatase activity and biomass yield significantly. In addition, the p H of the culture medium was reduced significantly by lecithin. The efficiency of the strain in releasing orthophosphate from organic phosphorus was studied in red soil(used in planting trees) and rice soil(originating as red soil). The available phosphorus content was increased by 230% after inoculating20 days in rice soil and decreased by 50% after inoculating 10 days in red soil. This work indicates that the yeast strain C. mycoderma has potential application for enhancing phosphorus utilization in plants that grow in rice soil. | Mang Yan Liufang Yu Liang Zhang Yuexia Guo Kewei Dai Yuru Chen | 2014 | Journal of Environmental Sciences2014，26，11： | 2 |
| 6 | Chromosome doubling mediates superior drought tolerance in Lycium ruthenicum via abscisic acid signaling显示文摘Plants are continuously affected by unfavorable external stimuli,which influences their productivity and growth.Differences in gene composition and expression patterns lead homologous polyploid plants to exhibit different physiological phenomena,among which enhanced environmental adaptability is a powerful phenotype conferred by polyploidization.The mechanisms underlying the differences in stress tolerance between diploids and autotetraploids at the molecular level remain unclear.In this research,a full-length transcription profile obtained via the singlemolecule real-time(SMRT)sequencing of high-quality single RNA molecules for use as background was combined with next-generation transcriptome and proteome technologies to probe the variation in the molecular mechanisms of autotetraploids.Tetraploids exhibited an increase in ABA content of 78.4%under natural conditions and a superior stress-resistance phenotype under severe drought stress compared with diploids.The substantial differences in the transcriptome profiles observed between diploids and autotetraploids under normal growth conditions were mainly related to ABA biosynthesis and signal transduction pathways,and 9-cis-epoxycarotenoid dioxygenase 1(NCED1)and NCED2,which encode key synthetic enzymes,were significantly upregulated.The increased expression of the ABREbinding factor 5-like(ABF5-like)gene was a pivotal factor in promoting the activation of the ABA signaling pathway and downstream target genes.In addition,ABA strongly induced the expression of osmotic proteins to increase the stress tolerance of the plants at the translational level.We consider the intrinsic mechanisms by which ABA affects drought resistance in tetraploids and diploids to understand the physiological and molecular mechanisms that enhance abiotic stress tolerance in polyploid plants. | Shupei Rao Yuru Tian Xinli Xia Yue Li Jinhuan Chen | 2020 | Horticulture Research2020，7，1： | 2 |
| 7 | The coloring mechanism of a novel golden variety in Populus deltoides based on the RGB color mode显示文摘Compared to flower color and red leaf mutants,the mechanism of yellow leaf formation in woody plants is more complicated and less understood.Poplars are common and widely distributed perennial trees.Here,we obtained a golden leaf mutant poplar variety(JHY)and compared it with its original green leaf poplar(Populus sp.Linn.‘2025’)in terms of phenotype,pigment content,the transcriptomes and metabolomes.Through transcriptome sequencing,we found that the chlorophyll degradation genes,and the genes in anthocyanin metabolism in JHY were up-regulated compared to L2025 and the carotenoid synthesis genes were down-regulated.Further based on HPLC-ESI-MS/MS technology,16 differentially expressed anthocyanins were identified,14 reddish anthocyanins of which were significantly up-regulated.According to these results,we proposed a coloring mechanism of JHY based on the RGB color mode.The yellow color of carotenoids and the red color of anthocyanins overlay each other,combined with a reduction in chlorophyll,turning the leaves golden.This study systematic analyzes the causes of golden leaf formation through the omics integration approach,which will provide reference for the breeding of golden leaf trees. | Yuru Tian Shupei Rao Qianqian Li Meng Xu Aike Wang Hechen Zhang Jinhuan Chen | 2021 | Forestry Research2021，1，1： | 2 |

| 12 | Formation of advanced glycation end products in raw and subsequently boiled broiler muscle:biological variation and effects of postmortem ageing and storage显示文摘The study aimed to investigate and compare the contents of carboxymethyllysine(CML)in two kinds of broilers during postmortem ageing and storage.The contents of CML in raw and boiled(100℃,30 min)broiler briskets and legs which were from white feather broilers(n=8)and yellow feather broilers(n=8)with ageing and storage at 4℃for 0-168 h were determined.Postmortem ageing and storage had a significant(P<0.05)effect on the color and A;in both boiled broilers meat.In addition,with the ageing and storage time increasing,CML content in raw white feather broiler brisket meat had no significant(P>0.05)change,while that in boiled brisket meat significantly(P<0.05)increased during 0-6 h,then decreased during 6-24 h,finally increased again.CML content in leg meat increased significantly(P<0.05)with the ageing and storage time prolonging.But postmortem ageing and storage had no significant(P>0.05)effect on the CML contents in raw/boiled yellow feather broilers.Meanwhile,CML contents in white feather broilers were much higher than that in yellow feather broilers.Thus,white feather broilers can be selected as the research object to study the mechanism of ageing and storage on CML content in the postmortem broiler in the future. | Suhong Huang Xiaoli Dong Yali Zhang Yuru Chen Yajie Yu Ming Huang Yuandong Zheng | 2022 | Food Science and Human Wellness2022，11，2： | 1 |
| 13 | Adding power of artificial intelligence to situational awareness of large interconnections dominated by inverter‐based resources显示文摘Large‐scale power systems exhibit more complex dynamics due to the increasing inte-gration of inverter‐based resources(IBRs).Therefore,there is an urgent need to enhance the situational awareness capability for better monitoring and control of power grids dominated by IBRs.As a pioneering Wide‐Area Measurement System,FNET/GridEye has developed and implemented various advanced applications based on the collected synchrophasor measurements to enhance the situational awareness capability of large‐scale power grids.This study provides an overview of the latest progress of FNET/GridEye.The sensors,communication,and data servers are upgraded to handle ultra‐high density synchrophasor and point‐on‐wave data to monitor system dynamics with more details.More importantly,several artificial intelligence(AI)‐based advanced appli-cations are introduced,including AI‐based inertia estimation,AI‐based disturbance size and location estimation,AI‐based system stability assessment,and AI‐based data authentication. | Lin Zhu Yinfeng Zhao Yi Cui Shutang You Wenpeng Yu Shengyuan Liu He Yin Chang Chen Yuru Wu Wei Qiu Mirka Mandich Hongyu Li Adedasola Ademola Chengwen Zhang Chujie Zeng Xinlan Jia Weikang Wang Haoyu Yuan Huaiguang Jiang Jin Tan Yilu Liu | 2021 | High Voltage2021，6，6： | 0 |
| 14 | Impact of age and tumor size on the development of the Kasabach-Merritt phenomenon in patients with kaposiform hemangioendothelioma:a retrospective cohort study显示文摘Introduction The Kasabach–Merritt phenomenon(KMP)is a severe complication of kaposiform hemangioendothelioma(KHE).The risk factors for KMP need further investigation.Methods The medical records of patients with KHE were reviewed.Univariate and multivariate logistic regression models were used for the risk factors for KMP,and the area under the receiver operator characteristic(ROC)curve was used to assess the predictive power of risk factors.Results A total of 338 patients with KHE were enrolled.The incidence of KMP was 45.9%.Age of onset(P<0.001,odds ratio[OR]0.939;95%confidence interval[CI]0.914–0.966),lesion size(P<0.001,OR 1.944;95%CI 1.646–2.296),mixed type(P=0.030,OR 2.428;95%CI 1.092–5.397),deep type(P=0.010,OR 4.006;95%CI 1.389–11.556),and mediastinal or retroperitoneal lesion location(P=0.019,OR 11.864;95%CI 1.497–94.003)were correlated with KMP occurrence through multivariate logistic regression.ROC curve analysis revealed that the optimal cutoffs were 4.75 months for the age of onset(P<0.001,OR 7.206,95%CI 4.073–12.749)and a lesion diameter of 5.35 cm(P<0.001,OR 11.817,95%CI 7.084–19.714).Bounded by a lesion size of 5.35 cm,we found significant differences in tumor morphology,age of onset,treatments,and hematological parameters.Using an onset age of 4.75 months as a cutoff,we found significant differences in tumor morphology,lesion size,hematological parameters,and prognosis.Conclusion For KHE patients with an onset age<4.75 months and/or lesion diameter>5.35 cm,clinicians should be wary of the occurrence of KMP.Active management is recommended to improve the prognosis. | Jiangyuan Zhou Yuru Lan Tong Qiu Xue Gong Zixin Zhang Chunshui He Qiang Peng Fan Hu Xuepeng Zhang Guoyan Lu Liqing Qiu Feiteng Kong Yongbo Zhang Siyuan Chen Yi Ji | 2023 | Precision Clinical Medicine2023，6，2： | 0 |
| 15 | Stable yellow light emission from lead-free copper halides single crystals for visible light communication显示文摘Yellow light-emitting diodes(LEDs) as soft light have attracted abundant attention in lithography room, museum and art gallery. However, the development of efficient yellow LEDs lags behind green and blue LEDs, and the available perovskites yellow LEDs suffer from the instability. Herein, a pressure-assisted cooling method is proposed to grow lead-free CsCu2I3single crystals, which possess uniform surface morphology and enhanced photoluminescence quantum yield(PLQY) stability, with only 10% PLQY losses after being stored in air after 5000 h.Then, the single crystals used for yellow LEDs without encapsulation exhibit a decent Correlated Color Temperature(CCT) of 4290 K, a Commission Internationale de l’Eclairage(CIE) coordinate of(0.38, 0.41), and an excellent 570-h operating stability under heating temperature of 100°C. Finally, the yellow LEDs facilitate the application in wireless visible light communication(VLC), which show a-3 dB bandwidth of 21.5 MHz and a high achievable data rate of 219.2 Mbps by using orthogonal frequency division multiplexing(OFDM) modulation with adaptive bit loading. The present work not only promotes the development of lead-free single crystals, but also inspires the potential of CsCu2I3in the field of yellow illumination and wireless VLC. | Baiqian Wang Yuru Tang Xin Yang Wensi Cai Ru Li Wen Ma Shuangyi Zhao Chen Chen Zhigang Zang | 2023 | Nano Materials Science2023，5，1： | 0 |

| 17 | Interactions between natural biofilm,substratum surface wettability,and mussel plantigrade settlement显示文摘Mytilus galloprovincialis is a major fouling organism in the inter-tidal zone.However,the interactions between M.galloprovincialis plantigrade settlement,biofilm characteristics,and surface wettability remains unknown.Here,we examined M.galloprovincialis plantigrade settlement responses to marine biofilms(BFs)on surfaces of varying wettability.No significant difference in mussel settlement was observed on young BFs(7 d)on surfaces of differing wettability;while settlement decreased on older BFs(14,21,and 28 d)formed on low compared to high wettability surfaces.Surface wettability affected BF characteristics.The standardized harmonic mean and water contact angles values were not correlated with diatom density and chlorophyll a concentration,but were correlated with bacterial density,dry weight,and thickness.Denaturing gradient gel electrophoresis revealed that bacterial community structure differed on BFs on surfaces of varying wettability.Thus,surface wettability affects biofilm characteristics,and the subsequent changes in BF characteristics may be responsible for the variation in biofilm-inducing activity of M.galloprovincialis plantigrade settlement. | YANG JinLong GUO XingPan DING DeWen GAO Wei HUANG DaoFen CHEN YuRu LIANG Xiao | 2017 | Science China Earth Sciences2017，60，2： | 0 |
| 18 | LDL receptor-related protein 1 (LRP1),a novel target for opening the blood-labyrinth barrier(BLB)显示文摘Inner ear disorders are a cluster of diseases that cause hearing loss in more than 1.5 billion people worldwide.However,the presence of the blood-labyrinth barrier(BLB)on the surface of the inner ear capillaries greatly hinders the effectiveness of systemic drugs for prevention and intervention due to the low permeability,which restricts the entry of most drug compounds from the bloodstream into the inner ear tissue.Here,we report the finding of a novel receptor,low-density lipoprotein receptor-related protein 1(LRP1),that is expressed on the BLB,as a potential target for shuttling therapeutics across this barrier.As a proof-ofconcept,we developed an LRP1-binding peptide,IETP2,and covalently conjugated a series of model small-molecule compounds to it,including potential drugs and imaging agents.All compounds were successfully delivered into the inner ear and inner ear lymph,indicating that targeting the receptor LRP1 is a promising strategy to enhance the permeability of the BLB.The discovery of the receptor LRP1 will illuminate developing strategies for crossing the BLB and for improving systemic drug delivery for inner ear disorders. | Xi Shi Zihao Wang Wei Ren Long Chen Cong Xu Menghua Li Shiyong Fan Yuru Xu Mengbing Chen Fanjun Zheng Wenyuan Zhang Xinbo Zhou Yue Zhang Shiwei Qiu Liyuan Wu Peng Zhou Xinze Lv Tianyu Cui Yuehua Qiao Hui Zhao Weiwei Guo Wei Chen Song Li Wu Zhong Jian Lin Shiming Yang | 2022 | Signal Transduction and Targeted Therapy2022，7，7： | 0 |
| 19 | Real-World COVID-19 Vaccine Protection Rates against Infection in the Delta and Omicron Eras显示文摘The real-world vaccine protection rates(VPRs)against the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection are critical in formulating future vaccination strategies against the virus.Based on a varying coefficient stochastic epidemic model,we obtain 7 countries’real-world VPRs using daily epidemiological and vaccination data,and find that the VPRs improved with more vaccine doses.The average VPR of the full vaccination was 82%(SE:4%)and 61%(SE:3%)in the pre-Delta and Deltadominated periods,respectively.The Omicron variant reduced the average VPR of the full vaccination to 39%(SE:2%).However,the booster dose restored the VPR to 63%(SE:1%)which was significantly above the 50%threshold in the Omicron-dominated period.Scenario analyses show that the existing vaccination strategies have significantly delayed and reduced the timing and the magnitude of the infection peaks,respectively,and doubling the existing booster coverage would lead to 29%fewer confirmed cases and 17%fewer deaths in the 7 countries compared to the outcomes at the existing booster taking rates.These call for higher full vaccine and booster coverage for all countries. | Yuru Zhu Jia Gu Yumou Qiu Song Xi Chen | 2023 | Research2023，，4： | 0 |
