| 1 | SINS model in the management of biosafety level 2 laboratories: exploration and practice显示文摘A significant number of biosafety level 2(BSL-2)laboratories have been established in many countries for studies of various types of pathogenic agents and other infectious biological materials.The harmonized management of biological risks in such diverse laboratories thus appears as a real challenge.Zhejiang Province in China has taken the initiative to establish a comprehensively integrated laboratory biosafety management system called SINS(Standardization,Informatization,Normalization and Systematization).The SINS model system has been introduced and adopted in 1,721 BSL-2 laboratories in Zhejiang Province,and thus lead to an increase in the number of biosafety committees from 20%to more than 95%from 2007 to 2018,and the number of biosafety laboratory managers who knows biosafety-related laws and regulations increase from 52.7%to 83.7%from 2009 to 2017.Such achievements indicate that the successful implementation of SINS model has increased the effective control of biological risks in BSL-2 laboratories of the Zhejiang Province.SINS model and its main effects on leading the improvement of laboratory biosafety management was presented in this review.The SINS model helps to strengthen laboratory biosafety and thus effectively reduces occurrence of biosafety-related incidences.This model can potentially be used by other regions or countries where harmonized biosafety management system is still under-developing. | Xiaoxia Qiu Jingqing Weng Zhenggang Jiang Congcong Yan Hua Gu | 2019 | Biosafety and Health2019，1，3： | 3 |
| 2 | Association of assisted reproductive technology, germline de novo mutations and congenital heart defects in a prospective birth cohort study显示文摘Emerging evidence suggests that children conceived through assisted reproductive technology(ART)have a higher risk of congenital heart defects(CHDs)even when there is no family history.De novo mutation(DNM)is a well-known cause of sporadic congenital diseases;however,whether ART procedures increase the number of germline DNM(gDNM)has not yet been well studied.Here,we performed whole-genome sequencing of 1137 individuals from 160 families conceived through ART and 205 families conceived spontaneously.Children conceived via ART carried 4.59 more gDNMs than children conceived spontaneously,including 332 paternal and 1.26 maternal DNMs,after correcting for parental age at conception,cigarette smoking,alcohol drinking,and exercise behaviors.Paternal DNMs in offspring conceived via ART are characterized by C>T substitutions at CpG sites,which potentially affect protein-coding genes and are significantly associated with the increased risk of CHD.In addition,the accumulation of non-coding functional mutations was independently associated with CHD and 87.9% of the mutations were originated from the father.Among ART offspring,infertility of the father was associated with elevated paternal DNMs;usage of both recombinant and urinary follicle-stimulating hormone and high-dosage human chorionic gonadotropin trigger was associated with an increase of maternal DNMs.In sum,the increased gDNMs in offspring conceived by ART were primarily originated from fathers,indicating that ART itself may not be a major reason for the accumulation of gDNMs.Our findings emphasize the importance of evaluating the germline status of the fathers in families with the use of ART. | Cheng Wang Hong Lv Xiufeng Ling Hong Li Feiyang Diao Juncheng Dai Jiangbo Du Ting Chen Qi Xi Yang Zhao Kun Zhou Bo Xu Xiumei Han Xiaoyu Liu Meijuan Peng Congcong Chen Shiyao Tao Lei Huang Cong Liu Mingyang Wen Yangqian Jiang Tao Jiang Chuncheng Lu Wei Wu Di Wu Minjian Chen Yuan Lin Xuejiang Guo Ran Huo Jiayin Liu Hongxia Ma Guangfu Jin Yankai Xia Jiahao Sha Hongbing Shen Zhibin Hu | 2021 | Cell Research2021，31，8： | 2 |
| 3 | The mechanism of dentine hypersensitivity:Stimuli-induced directional cation transport through dentinal tubules显示文摘Dentine hypersensitivity is an annoying worldwide disease,yet its mechanism remains unclear.The long-used hydrodynamic theory,a stimuli-induced fluid-flow process,describes the pain processes.However,no experimental evidence supports the statements.Here,we demonstrate that stimuli-induced directional cation transport,rather than fluid-flow,through dentinal tubules actually leads to dentine hypersensitivity.The in vitro/in vivo electro-chemical and electro-neurophysiological approaches reveal the cation current through the nanoconfined negatively charged dentinal tubules coming from external stimuli(pressure,pH,and temperature)on dentin surface and further triggering the nerve impulses causing the dentine hypersensitivity.Furthermore,the cationic-hydrogels blocked dentinal tubules could significantly reduce the stimuli-triggered nerve action potentials and the anionhydrogels counterpart enhances those,supporting the cation-flow transducing dentine hypersensitivity.Therefore,the inspired ion-blocking desensitizing therapies have achieved remarkable pain relief in clinical applications.The proposed mechanism would enrich the basic knowledge of dentistry and further foster breakthrough initiatives in hypersensitivity mitigation and cure. | Nuo Chen Jingjing Deng Shengjie Jiang Xiang-Yu Kong Teng Zhou Kai Zhao Zuohui Xiao Huimin Zheng Weipeng Chen Congcong Zhu Xinyu Liu Liping Wen Yan Wei Xuliang Deng Lei Jiang | 2023 | Nano Research2023，16，1： | 2 |
| 4 | Analysis of QTLs for erucic acid and oil content in seeds on A8 chromosome and the linkage drag between the alleles for the two traits in Brassica napus显示文摘The history of canola breeding began with the discovery of germplasm with low erucic acid content in seeds of spring forage cultivar in the 1950's.FAE1 mutations led to a dramatic decrease of the seed erucic acid content in Arabidopsis thaliana.The products of the two FAE1 loci,BnA8.FAE1 and BnC3.FAE1,showed additive effects to the level of erucic acid content in oilseed rape.Previous research believed that the pleiotropy of FAE1 was responsible for the decrease in seed oil content along with the reduction of seed erucic acid content in the modern cultivars.TN DH population was developed from a canola cultivar Tapidor and a Chinese traditional cultivar Ningyou7.The population had been tested in 10 and 11 environments to map QTLs for the erucic acid content and oil content in seeds.As the map resolution increased,a novel QTL for seed erucic acid content was revealed,after Meta-analysis,7 cM away from the most significant seed erucic acid content QTL where BnA8.FAE1 is located.Seven independent QTLs for seed oil content(qOC) were detected around the two seed erucic acid content QTLs(qEA) across 39.20 cM on linkage group A8.Two of the qOCs co-localized with the two qEAs,respectively,and were detected in a single environment.The other five qOCs were detected in 10 of 11 environments independent of qEAs.Alleles from Tapidor in all the QTLs at the 0-39.20 cM region contributed negative effects to either erucic acid content or oil content in seeds.Parallel,geno-typing showed that on 5 of the 7 QTLs regions,Tapidor alleles had the same genotypes with that in 'Liho',the original low seed erucic acid content source.Through rounds of crossbreeding with oil-cropped cultivars and intensive selection for multi generations,Tapidor still had the inferior alleles for low seed oil content from 'Liho',the forage rape.This showed a strong linkage drag of low seed oil content,which was controlled by the five qEA-independent qOCs,with low seed erucic acid content.Ninety cultivars of B.napus from 8 countries were used to analyze the genetic drag with 9 molecular markers located in the QTL confidence intervals(24.04 cM) on linkage group A8.It was noticed that more than 46% of the cultivars with low seed erucic acid content trait remained the genotype of low seed oil content at least in one locus.Backcross and marker-assisted selection could break the genetic drag between the low oil content and erucic acid in seeds in the process for breeding modern high seed oil content canola cultivars. | Zhengying Cao Fang Tian Nian Wang Congcong Jiang Bing Lin Wei Xia Jiaqin Shi Yah Long Chunyu Zhang Jinling Meng | 2010 | Journal of Genetics and Genomics2010，37，4： | 2 |
| 5 | Process performance and quality attributes of temperature and step-down relative humidity controlled hot air drying of Panax notoginseng roots显示文摘The effects of temperature and step-down relative humidity controlled hot-air drying(THC-HAD)on the drying kinetics,energy efficiency and quality,i.e.,rehydration ratio(RR),color parameters(L*,a*,b*),total color difference(ΔE*),Panax notoginseng saponins(PNS)content,and ginsenosides content(R1,Rg1,Re,Rd,Rb1)of Panax notoginseng roots were evaluated.The drying time was significantly affected by the drying temperature followed by the relative humidity(RH)of the drying air.Special combination of drying conditions,i.e.,drying temperature of 50°C,relative humidity of 40%for 3 h and then continuous dehumidification from 40%to 8%allowed to shorten the drying time by 25%compared to drying at the same temperature and continuous dehumidification.The longer was the drying time under constant high RH of drying air,the lower was the RR of dried samples.The step-down RH strategy contributed to the formation of a porous structure,enhancement of drying efficiency and quality improvement.Generally,the ginsenosides content increased with the increase in temperature,while no obvious trend was recorded for ginsenoside R1.The contents of the ginsenoside R1,Rg1,Rb1 and PNS decreased with the increase in the drying time under constant high RH.Taking into account the drying time,energy consumption and quality attributes,drying at the temperature of 50°C,constant RH of 40%for 3 h and then step-down RH from 40%to 8%was proposed as the most favorable combination of drying conditions for dehydration of whole Panax notoginseng roots. | Dalong Jiang Congcong Li Sara Zielinska Yanhong Liu Zhenjiang Gao Rongyan Wang Zhi’an Zheng | 2021 | International Journal of Agricultural and Biological Engineering2021，14，6： | 1 |
| 6 | Research Article Core/hybrid-shell structures boost thermoelectric performance of flexible inorganic/organic nanowire films显示文摘Interface control in inorganic/organic composites has always been regarded as one of the effective means to optimize their thermoelectric(TE)performance,and the past few years have witnessed its development,including carrier-energy filtering and phonon scattering.However,the energy barrier created by the band alignment at the composite interface depends on the Fermi level difference between the organic and inorganic components,which is difficult to be controlled by the common means.Herein,a core/hybrid-shell strategy aiming for efficient interface control is proposed to tune the energy barrier of the inorganic/organic core/shell nanowire interface.The Fermi level of hybrid-shell can be effectively controlled by separating the charge carriers compared to the single-shell composites.The energy barrier of the core/hybrid-shell interface is tuned to an appropriate position,and the energy filtering effect is utilized,resulting in a substantial improvement in power factor and reduction in thermal conductivity for the prepared core/hybrid-shell composites with good air-stability and flexibility.Moreover,both the flexible p type and p-n type TE devices based on the prepared core/hybrid-shell films yield excellent output properties with the maximum power densities of 41 and 45μW·cm^(−2)at a temperature difference of ca.30 K,respectively.This study provides a novel strategy to improve the TE performance of the inorganic/organic composites,displaying great potential for low-power wearable electronics. | Changcun Li Xiaoqi Lan Peipei Liu Jingkun Xu Qinglin Jiang Congcong Liu Cheng Liu Fengxing Jiang | 2023 | Nano Research2023，16，4： | 1 |
| 7 | The E3 ubiquitin ligase OsRGLG5 targeted by the Magnaporthe oryzae effector AvrPi9 confers basal resistance against rice blast显示文摘Rice blast,caused by Magnaporthe oryzae,is one of the most devastating diseases of rice.During infection,M.oryzae secretes effectors to facilitate blast development.Among these effectors,the avirulence factor AvrPi9 is recognized by Pi9,a broad-spectrum blast resistance protein that triggers Pi9-mediated resistance in rice.However,little is known about the interaction between AvrPi9 and Pi9 and how AvrPi9 exerts virulence to promote infection.In this study,we found that ectopic expression of AvrPi9 in the Pi9-lacking cultivar TP309 suppressed basal resistance against M.oryzae.Furthermore,we identified an AvrPi9-interacting protein in rice,which we named OsRGLG5,encoding a functional RING-type E3 ubiquitin ligase.During infection,AvrPi9 was ubiquitinated and degraded by OsRGLG5.Meanwhile,AvrPi9 affected the stability of OsRGLG5.Infection assays revealed that OsRGLG5 is a positive regulator of basal resistance against M.oryzae,but it is not essential for Pi9-mediated blast resistance in rice.In conclusion,our results revealed that OsRGLG5 is targeted by the M.oryzae effector AvrPi9 and positively regulates basal resistance against rice blast. | Zhiquan Liu Jiehua Qiu Zhenan Shen Congcong Wang Nan Jiang Huanbin Shi Yanjun Kou | 2023 | Plant Communications2023，4，5： | 1 |

| 10 | The proximity between hydroxyl and single atom determines the catalytic reactivity of Rh1/CeO_(2) single-atom catalysts显示文摘The local structure of the metal single-atom site is closely related to the catalytic activity of metal single-atom catalysts(SACs).However,constructing SACs with homogeneous metal active sites is a challenge due to the surface heterogeneity of the conventional support.Herein,we prepared two Rh1/CeO_(2)SACs(0.5Rh1/r-CeO_(2)and 0.5Rh1/c-CeO_(2),respectively)using two shaped CeO_(2)(rod and cube)exposing different facets,i.e.,CeO_(2)(111)and CeO_(2)(100).In CO oxidation reaction,the T100 of 0.5Rh1/r-CeO_(2)SACs is 120°C,while the T100 of 0.5Rh1/c-CeO_(2)SACs is as high as 200°C.Via in-situ CO diffuse reflectance infrared Fourier transform spectroscopy(CO-DRIFTS),we found that the proximity between OH group and Rh single atom on the plane surface plays an important role in the catalytic activity of Rh1/CeO_(2)SAC system in CO oxidation.The Rh single atom trapped at the CeO_(2)(111)crystal surface forms the Rh1(OH)adjacent species,which is not found on the CeO_(2)(100)crystal surface at room temperature.Furthermore,during CO oxidation,the OH group far from Rh single atom on the 0.5Rh1/c-CeO_(2)disappears and forms Rh1(OH)adjacent species when the temperature is above 150°C.The formation of Rh1(OH)adjacentCO intermediate in the reaction is pivotal for the excellent catalytic activity,which explains the difference in the catalytic activity of Rh single atoms on two different CeO_(2)planes.The formed Rh1(OH)adjacent-O-Ce structure exhibits good stability in the reducing atmosphere,maintaining the Rh atomic dispersion after CO oxidation even when pre-reduced at high temperature of 500°C.Density functional theory(DFT)calculations validate the unique activity and reaction path of the intermediate Rh1(OH)adjacentCO species formed.This work demonstrates that the proximity between metal single atom and hydroxyl can determine the formation of active intermediates to affect the catalytic performances in catalysis. | Danfeng Wu Shuyun Zhou Congcong Du Juan Li Jianyu Huang Hong-xia Shen Abhaya K.Datye Shan Jiang Jeffrey T.Miller Sen Lin Haifeng Xiong | 2024 | Nano Research2024，17，1： | 0 |
| 11 | Generating homozygous mutant populations of barley microspores by ethyl methanesulfonate treatment显示文摘Induced mutations are important for genetic research and breeding.Mutations induced by physical or chemical mutagenesis are usually heterozygous during the early generations.However,mutations must be fixed prior to phenotyping or field trials,which requires additional rounds of self-pollination.Microspore culture is an effective method to produce double-haploid(DH)plants that are fixed homozygotes.In this study,we conducted ethyl methanesulfonate(EMS)-induced mutagenesis of microspore cultures of barley(Hordeum vulgare)cultivar‘Hua30’and landrace‘HTX’.The EMS concentrations were negatively correlated with the efficiency of callus induction and the frequency of mutant plant regeneration.The two genotypes showed different regeneration efficiencies.The phenotypic variation of the regenerated M1 plants and the presence of genome-wide nucleotide mutations,revealed by whole-genome sequencing,highlight the utility of EMS-induced mutagenesis of isolated microspore cultures for developing DH mutants.Genome-wide analysis of the mutation frequency in the regenerated plants revealed that a considerable proportion of mutations resulted from microspore culture(somaclonal variation)rather than EMS-induced mutagenesis.In addition to producing a population of 1972 homozygous mutant lines that are available for future field trials,this study lays the foundation for optimizing the regeneration efficiency of DH plants and the richness of mutations(mainly by fine-tuning the mutagen dosage). | Linli Huang Guangqi Gao Congcong Jiang Guimei Guo Qiang He Yingjie Zong Chenghong Liu Ping Yang | 2023 | aBIOTECH2023，4，3： | 0 |
| 12 | A reference-guided TILLING by amplicon-sequencing platform supports forward and reverse genetics in barley显示文摘Barley is a diploid species with a genome smaller than those of other members of the Triticeae tribe,making it an attractive model for genetic studies in Triticeae crops.The recent development of barley genomics has created a need for a high-throughput platform to identify genetically uniform mutants for gene function investigations.In this study,we report an ethyl methanesulfonate(EMS)-mutagenized population consisting of 8525M_(3) lines in the barley landrace“Hatiexi”(HTX),which we complement with a high-quality de novo assembly of a reference genome for this genotype.The mutation rate within the population ranged from 1.51 to 4.09 mutations per megabase,depending on the treatment dosage of EMS and the mutation discrimination platform used for genotype analysis.We implemented a three-dimensional DNA pooling strategy combined with multiplexed amplicon sequencing to create a highly efficient and cost-effective TILLING(targeting induced locus lesion in genomes)platform in barley.Mutations were successfully identified from 72 mixed amplicons within a DNA pool containing 64 individual mutants and from 56 mixed amplicons within a pool containing 144 individuals.We discovered abundant allelic mutants for dozens of genes,including the barley Green Revolution contributor gene Brassinosteroid insensitive 1(BRI1).As a proof of concept,we rapidly determined the causal gene responsible for a chlorotic mutant by following the MutMap strategy,demonstrating the value of this resource to support forward and reverse genetic studies in barley. | Congcong Jiang Miaomiao Lei Yu Guo Guangqi Gao Lijie Shi Yanlong Jin Yu Cai Axel Himmelbach Shenghui Zhou Qiang He Xuefeng Yao Jinhong Kan Georg Haberer Fengying Duan Lihui Li Jun Liu Jing Zhang Manuel Spannagl Chunming Liu Nils Stein Zongyun Feng Martin Mascher Ping Yang | 2022 | Plant Communications2022，3，4： | 0 |
| 13 | Ion transport regulation through triblock copolymer/PET asymmetric nanochannel membrane:Model system establishment and rectification mapping显示文摘Controlling ions transport across the membrane at different pH environments is essential for the physiological process and artificial systems.Many efforts have been devoted to pH-responsive ion gating,while rarely systems can maintain the rectification in pH-changing environments.Here,a composite nanochannel system is fabricated,which shows unidirectional rectification with high performance in a wide pH range.In the system,block copolymer(BCP) and polyethylene te rephthalate(PET) are employed for the amphoteric nanochannels fabrication.Based on the composite system,a model is built for the theoretical simulation.Thereafter,rectification mapping is conducted on the system,which can provide abundant info rmation about the relations between charge distribution and ions transport prope rties.The proposed rectification mapping can definitely help to design new materials with special ion transport properties,such as high-performance membranes used in the salinity gradient power generation field. | Linsen Yang Pei Liu Congcong Zhu Yuanyuan Zhao Miaomiao Yuan Xiang-Yu Kong Liping Wen Lei Jiang | 2021 | Chinese Chemical Letters2021，32，2： | 0 |
| 14 | Liquid discharge plasma for fast biomass liquefaction at mild conditions: The effects of homogeneous catalysts显示文摘Non-thermal plasma exhibits unique advan-tages in biomass conversion for the sustainable production of higher-value energy carriers.Different homogeneous catalysts are usually required for plasma-enabled biomass liquefaction to achieve time-and energy-efficient conver-sions.However,the effects of such catalysts on the plasma-assisted liquefaction process and of the plasma on those catalysts have not been thoroughly studied.In this study,an electrical discharge plasma is employed to promote the direct liquefaction of sawdust in a mixture of polyethylene glycol 200 and glycerol.Three commonly used chemicals,sulfuric acid,nitric acid and sodium p-toluene sulfate,were selected as catalysts.The effects of the type of catalyst and concentration on the liquefaction yield were examined;further,the roles of the catalysts in the plasma liquefaction process have been discussed.The results showed that the liquefaction yield attains a value of 90%within 5 min when 1%sulfuric acid was employed as the catalyst.Compared with the other catalysts,sulfuric acid presents the highest efficiency for the liquefaction of sawdust.It was observed that hydrogen ions from the catalyst were primarily responsible for the significant thermal effects on the liquefaction system and the generation of large quantities of active species;these effects directly con-tributed to a higher efficacy of the plasma-enabled liquefaction process. | Sen Wang Shiyun Liu Danhua Mei Rusen Zhou Congcong Jiang Xianhui Zhang Zhi Fang Kostya(Ken)Ostrikov | 2020 | Frontiers of Chemical Science and Engineering2020，14，5： | 0 |
| 15 | Monte Carlo simulation based thinning and calculating method for noninvasive blood glucose sensing by near-infrared spectroscopy显示文摘Previous results show that the floating reference theory(FRT)is an effective tool to reduce the infuence of interference factors on noninvasive blood glucose sensing by near infrared spectros-copy(NIRS).It is the key to measure the floating reference point(FRP)precisely for the application of FRT.Monte Carlo(MC)simulation has been introduced to quantitatively in-vestigate the effects of positioning errors and light source drifts on measuring FRP.In this article,thinning and calculating method(TCM)is proposed to quantify the positioning error.Mean-while,the normalization process(NP)is developed to significantly reduce the error induced by light source drift.The results according to TCM show that 7 purm deviations in positioning can generate about 10.63%relative error in FRP.It is more noticeable that 1%fluctuation in light source intensity may lead to 12.21%relative errors.Gratifyingly,the proposed NP model can effectively reduce the error caused by light source drift.Therefore,the measurement system for FRPs must meet that the positioning error is less than 7 purm,and the light source drift is kept within 1%.Furthermore,an improvement for measurement system is proposed in order to take advantage of the NP model. | Congcong Ma Jia Qin Qi Zhang Junsheng Lu Kexin Xu Jingying Jiang | 2017 | Journal of Innovative Optical Health Sciences2017，，2： | 0 |
| 16 | A Non-toxic and Efficient Method for Extracting DNA and RNA from Peanut显示文摘[Objectives]To establish a non-toxic and efficient method for extracting DNA and total RNA from peanuts and laying a solid foundation for the molecular biology study of peanuts.[Methods]Based on the principle and method of purifying nucleic acids by silica gel adsorption at high salt and low pH condition,a non-toxic and efficient method to extract peanut DNA and total RNA using cetyltrimethyl ammonium bromide(CTAB)extraction solution was designed.The quality and purity of nucleic acids were detected by agarose gel electrophoresis and nucleic acids protein analyzer,respectively.The quality of DNA was further verified by enzyme digestion and PCR amplification using molecular marker techniques.The quality of total RNA was further verified by reverse transcription(RT)-PCR of actin gene and cDNA-SCoT gene differential display technique.[Results]The agarose gel electrophoresis test showed that the peanut DNA extracted by a low-toxic and effective method is free of contamination and degradation.Through the detection by the nucleic acid protein analyzer,the DNA concentration,yield,A260/A280 and A260/A230 of 5 peanut varieties were 419.6-498.2 ng/μL,20.98-24.91μg/g,1.89-1.96 and 2.03-2.28,respectively.The DNA was of high quality and can be completely digested by EcoRI restriction enzymes,and also can be used for SCoT and SRAP molecular marker technology analysis.The RNA extracted from different tissues of peanuts showed no visible DNA bands by non-denaturing agarose gel electrophoresis.The separated 28S bands were brighter than 18S.The ratio of A260/A280 and A260/A230 showed that the RNA quality was good and can be used for reverse transcription,RT-PCR of actin gene and amplification of cDNA-SCoT gene differential display technique.[Conclusions]This experiment established a low-toxic and effective method for extracting DNA and total RNA from peanuts.Compared with traditional methods,this method is more time-saving and cheaper than commercial kits.The most important point is that this method does not use toxic reagents such as phenol,chloroform and isopropanol.Thus,it is expected to be widely applied in molecular biology research. | Jing LIU Congcong WANG Jing JIANG Zhuqiang HAN Xiumei TANG Lihang QIU Liangqiong HE Ruichun ZHONG Zhipeng HUANG Haining WU Ronghua TANG Junxian LIU Faqian XIONG | 2021 | Asian Agricultural Research2021，13，1： | 0 |
| 17 | Experimental and numerical study on the shrinkage-deformation of carrot slices during hot air drying显示文摘In order to further understand the mechanism of material volume change in the drying process,numerical simulations(considering or neglecting shrinkage)of heat and mass transfer during convective drying of carrot slices under constant and controlled temperature and relative humidity were carried out.Simulated results were validated with experimental data.The results of the simulation show that the Quadratic model fitted well to the moisture ratio and the material temperature data trend with average relative errors of 5.9%and 8.1%,respectively.Additionally,the results of the simulation considering shrinkage show that the moisture and temperature distributions during drying are closer to the experimental data than the results of the simulation disregarding shrinkage.The material moisture content was significantly related to the shrinkage of dried tissue.Temperature and relative humidity significantly affected the volume shrinkage of carrot slices.The volume shrinkage increased with the rising of the constant temperature and the decline of relative humidity.This model can be used to provide more information on the dynamics of heat and mass transfer during drying and can also be adapted to other products and dryers devices. | Dalong Jiang Congcong Li Zifan Lin Yuntian Wu Hongjuan Pei Magdalena Zielinska Hongwei Xiao | 2023 | International Journal of Agricultural and Biological Engineering2023，16，1： | 0 |
| 18 | Visual Comparison of Customer Stickiness in Retail Stores显示文摘Understanding market trends and forming competitive promotion strategies has always been a major task of retail store managers. One big challenge is the lack of effective tools for in-depth customer behavior analysis. In this paper, we apply visual analytics techniques to address the challenge, which is built up on the emerging and mobile location big data. We present a system that focuses on the analysis of customer stickiness which represents customers' affinity to retail stores. The system integrates mobile data pre-processing, customer stickiness analysis, multi-view visualization, and a set of interactions.The visual analytics techniques are mainly designed for two types of user tasks: 1) understanding the spatio-temporal distribution of customer traces related to retail stores; 2)evaluating the performance and trend of multiple retail stores through visual comparison. We have demonstrated the effectiveness of the system through two case studies including advertisement placement and business branch reconfiguration. | JIANG Tao SHI Lei ZHAO Ye ZHANG Xiatian LU Yao HUANG Congcong | 2018 | Chinese Journal of Electronics2018，27，5： | 0 |
| 19 | Highly responsive biosensors based on organic field-effect transistors under light irradiation显示文摘High responsivity and sensitivity play essential roles in the development of organic field-effect transistors(OFETs)-based biosensors with regard to biological detections,particularly for disease diagnosis.Nonetheless,how to design a biosensor which improves these two outstanding properties while achieving low cost,easy processing,and time saving is a daunting challenge.Herein,a novel biosensor based on OFET with copolymer thin film,whose surface is illuminated with a suitable light beam is reported.This film can be used as both an organic semiconductor material and as a photoelectric active material.Due to amplification of signals as a result of the film’s strong response to light,the biosensor possesses higher responsivity and sensitivity compared to dark condition and even realizes a maximum responsivity of up to 10^(3)for alpha-fetoprotein(AFP)detection.The simple combination of light and transistor builds a bridge between photoelectric effect and biological system.In addition,the emergence of more excellent photoelectric active materials is expected to pave a way for ultrasensitive bio-chemical diagnostic tools. | Xiaoqian Jiang Chenfang Sun Congcong Zhang Shanshan Cheng | 2021 | Chinese Chemical Letters2021，32，11： | 0 |
| 20 | Genomic Shift in Population Dynamics of mcr-1-positive Escherichia coli in Human Carriage显示文摘Emergence of the colistin resistance gene,mcr-1,has attracted worldwide attention.Despite the prevalence of mcr-1-positive Escherichia coli(MCRPEC)strains in human carriage showing a significant decrease between 2016 and 2019,genetic differences in MCRPEC strains remain largely unknown.We therefore conducted a comparative genomic study on MCRPEC strains from fecal samples of healthy human subjects in 2016 and 2019.We identified three major differences in MCRPEC strains between these two time points.First,the insertion sequence ISApl1 was often deleted and the percentage of mcr-1-carrying IncI2 plasmids was increased in MCRPEC strains in 2019.Second,the antibiotic resistance genes(ARGs),aac(3)-IVa and blaCTX-M-1,emerged and coexisted with mcr-1 in 2019.Third,MCRPEC strains in 2019 contained more virulence genes,resulting in an increased proportion of extraintestinal pathogenic E.coli(ExPEC)strains(36.1%)in MCRPEC strains in 2019 compared to that in 2016(10.5%),implying that these strains could occupy intestinal ecological niches by competing with other commensal bacteria.Our results suggest that despite the significant reduction in the prevalence of MCRPEC strains in humans from 2016 to 2019,MCRPEC exhibits increased resistance to other clinically important ARGs and contains more virulence genes,which may pose a potential public health threat. | Yingbo Shen Rong Zhang Dongyan Shao Lu Yang Jiayue Lu Congcong Liu Xueyang Wang Junyao Jiang Boxuan Wang Congming Wu Julian Parkhill Yang Wang Timothy R.Walsh George F.Gao Zhangqi Shen | 2022 | Genomics, Proteomics & Bioinformatics2022，20，6： | 0 |
