| 1 | Adversarial Attacks on Content-Based Filtering Journal Recommender Systems显示文摘Recommender systems are very useful for people to explore what they really need.Academic papers are important achievements for researchers and they often have a great deal of choice to submit their papers.In order to improve the efficiency of selecting the most suitable journals for publishing their works,journal recommender systems(JRS)can automatically provide a small number of candidate journals based on key information such as the title and the abstract.However,users or journal owners may attack the system for their own purposes.In this paper,we discuss about the adversarial attacks against content-based filtering JRS.We propose both targeted attack method that makes some target journals appear more often in the system and non-targeted attack method that makes the system provide incorrect recommendations.We also conduct extensive experiments to validate the proposed methods.We hope this paper could help improve JRS by realizing the existence of such adversarial attacks. | Zhaoquan Gu Yinyin Cai Sheng Wang Mohan Li Jing Qiu Shen Su Xiaojiang Du Zhihong Tian | 2020 | Computers, Materials & Continua2020，，9： | 2 |
| 2 | Research Progress on Effects of Stocking Density on Performance, Health and Welfare of Duck显示文摘Stocking density is an important factor for animal production performance.It appears particularly urgent and important to research systematically on stocking density for the dual restriction of environmental protection and animal welfare.This review dealt with the influence of stocking density on ducks'productivity and health through production performance,animal behavior and animal welfare,and analyzed the possible mechanism of high stocking density reducing production performance,resulting in abnormal behavior and stress,causing welfare and health problems.We consider that it might be associated with heat stress,more spatial competition(to gather the food,drinking water,sports area,etc.),as well as the quality deterioration of litter and house air caused by high stocking density.Finally,we put forward some suggestions on the study of stocking density's effects on ducks,and proposed the future work that need to be studied and problems that need to be solved imminently. | Chaowu YANG Chunlin YU Zengrong ZHANG Mohan QIU Huarui DU Qingyun LI Xiaosong JIANG Xia XIONG | 2020 | Agricultural Biotechnology2020，9，4： | 1 |
| 3 | Genetic and Breeding Progress Analysis on Five Pure Lines of Dahen Broiler显示文摘To timely modify breeding scheme and improve selection efficiency of Dahen broiler,genetic and breeding progress analysis on five pure lines was conducted. The results showed that the selection on breeding goal traits of each line was effective since 14 generations,especially the selection on growth traits did not cause adverse influence on reproductive performance. After the 6 thgeneration,main performances of each line maintained in higher level,but the breeding progress obviously declined. It illustrated that current breeding means was effective for maintaining and consolidating breeding goal traits of Dahen broiler,and it should timely adjust breeding scheme to obtain more genetic progress. | Chaowu YANG Huarui DU Zengrong ZHANG Mohan QIU Chunlin YU Lan LIU Xiaoyu JIANG Bo XIA Chenming HU Xiaoyan SONG Xia XIONG Li YANG Han PENG Qingyun LI Xiaosong JIANG | 2018 | Agricultural Biotechnology2018，7，5： | 1 |

| 5 | Evaluating the Topology Coverage of BGP Monitors显示文摘BGP monitors are currently the main data resource of AS-level topology measurement,and the integrity of measurement result is limited to the location of such BGP monitors.However,there is currently no work to conduct a comprehensive study of the range of measurement results for a single BGP monitor.In this paper,we take the first step to describe the observed topology of each BGP monitor.To that end,we first investigate the construction and theoretical up-limit of the measured topology of a BGP monitor based on the valley-free model,then we evaluate the individual parts of the measured topology by comparing such theoretical results with the actually observed data.We find that:1)for more than 90%of the monitors,the actually observed peer-peer links merely takes a small part of all theoretical visible links;2)increasing the BGP monitors in the same AS may improve the measurement result,but with limited improvement;and 3)deploying multiple BGP monitors in different ASs can significantly improve the measurement results,but non-local BGP monitors can hardly replace the local AS BGP monitors.We also propose a metric for monitor selection optimization,and prove its effectiveness with experiment evaluation. | Shen Su Zhihong Tian Jing Qiu Yu Jiang Yanbin Sun Mohan Li Dunqiu Fan Haining Yu | 2020 | Computers, Materials & Continua2020，，3： | 0 |
| 6 | Report on the Breeding of Dahen 799 Broilers显示文摘[Objectives]This study was conducted to improve the production efficiency of dark-shank partridge-like plumage high-quality broilers and ensure animal welfare,so as to meet the development needs of China’s yellow-feather broiler industry.[Methods]Sichuan Animal Science Academy and Sichuan Dahen Poultry Breeding Co.,Ltd.formed a joint breeding research team.The team bred Dahen 799 broiler complete set line with local chicken breeds as the main material and improving production efficiency,stabilizing meat quality and flavor and achieving autosexing of chicks as the main breeding goals by modern poultry breeding technologies,after 10 years and 8 generations.[Results]The Dahen 799 broiler complete set line was approved by National Commission of Livestock and Poultry Genetic Resources in December 2020.The 66-week-old egg production of the breed reached 189 eggs.For the commercial generation,cocks and hens showed 10-week-old weights of 2668 and 2269 g,respectively;the feed conversion ratio was 2.26-2.35;the survivability was 96.7%-97.2%;and the average intramuscular fat contents of cocks and hens were in the range of 1.8%-2.1%,and the inosinic acid contents were in the range of 2.3-3.2 mg/g.The production performance and meat flavor of Dahen 799 broilers were better than Dahen 699 broilers,Sichuan mountainous bone-black chickens and two other social breeds.Compared with Sichuan mountainous bone-black chickens,the egg production at the age of 66 weeks increased by 47 eggs;the average weight of cocks and hens of the commercial generation at 10 weeks increased by 45.21%;and the autosexing rate of chicks of the commercial generation reached 99.3%.[Conclusions]Dahen 799 broilers have the advantages of good production performance,high feed conversion ratio and excellent meat flavor and the characteristic of autosexing which other breeds do not have,and can fully meet the industrial development needs of dark shanks and partridge-like plumage broilers. | Chaowu YANG Chunlin YU Mohan QIU Zengrong ZHANG Chenming HU Huarui DU Qingyun LI Xia XIONG Shiliang ZHU Siyang LIU Xiaosong JIANG | 2022 | Agricultural Biotechnology2022，11，3： | 0 |
| 7 | Optimized Design of Intelligent Management and Analysis System for Broiler Breeding Information显示文摘For a long time,the management and analysis of broiler breeding information in China remain in the 1.0 era of manual recording,careless processing,non-standard analysis and non-standard filing,and lack of accurate and intelligent information management and analysis system,which limit the development of broiler breeding industry.Based on the actual needs of broiler breeding in China,the project team focused on the collection,management and analysis of broiler breeding information and successfully developed Intelligent Management and Analysis System for Broiler Breeding Information.The system is the most complete management and analysis system of broiler breeding information in China,which is closely combined with practice.It has been successfully applied to broiler breeding by more than 10 breeding institutions in China,some of which are national-level core broiler breeding farms.The successful development and application of the system will effectively improve the efficiency of broiler breeding in China,narrow the gap between China and developed countries,open the 2.0 era of precise,intelligent and modular broiler breeding,and improve the core competitiveness of broiler breeding in China. | Yang Chaowu Yu Chunlin Qiu Mohan Zhang Zenrong Hu Chenming Xiong Xia Yang Li Peng Han Xia Bo Chen Jialei Du Huarui Li Qingyun Jiang Xiaosong | 2020 | Animal Husbandry and Feed Science2020，12，2： | 0 |
| 8 | Small RNA Sequencing Reveals Differentially Expressed piRNAs Related to Hypoxia in Tibetan Chickens显示文摘The relevance of genetic mechanism to the phenotype of hypoxic adaptation remains elusive.Tibetan chickens typically used to investigate the mechanism for the adaptation of hypoxia and the recognition of hypoxia-related piRNA remains an open issue.The purpose of this study was to illustrate whether the piRNAs were related to hypoxic adaptation.First of all,the differentially expressed piRNAs(DEpiRNAs)were identified through RNA sequencing between the Tibetan chickens and Daheng broilers.Subsequently,the target genes of DEpiRNAs were predicted and annotated by software.The network was constructed by Cytoscape.In our study,a total of 277 DEpiRNAs(33 down-regulated,244 up-regulated)were identified in the Tibetan chickens compared with the Daheng broilers.All of the 277 DEpiRNAs predicted 36658 targeted genes.Gene Ontology(GO)analysis showed that the target genes were significantly enriched in the biological process correlated with proliferation and apoptosis of cells,including cell cycle,mitochondrial outer membrane permeabilization,and positive regulation of stress-activated mitogen-activated protein kinase cascade.Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis implicated that the DEpiRNAs were mainly involved in immune and metabolism,including natural killer cell-mediated cytotoxicity,toll-like receptor signaling pathway and fatty acid metabolism.Furthermore,a predicted network with four piRNAs acted on 11 pathways via interacting with 22 target genes,in which piR-gga-1368839 regulated metabolic pathways by acting on DHCR24.In conclusion,we determined the DEpiRNAs in the Tibetan chickens and found that these piRNAs were associated with metabolism,which may be favorable for researching the biological adaptation to hypoxic stress. | Zengrong ZHANG Xiaosong JIANG Mohan QIU Chunlin YU Huarui DU Qingyun LI Han PENG Xia XIONG Xiaoyan SONG Chenming HU Jialei CHEN Chaowu YANG | 2022 | Agricultural Biotechnology2022，11，4： | 0 |
| 9 | Genetic and Breeding Progress Analysis on S06M Line of Dahen Broiler显示文摘The genetic and breeding progress of Dahen S06M line was analyzed, in order to improve the selection efficiency. The results showed that six generations of selection was effective in selecting main characters of S06M line, especially the selection of growth rate had no adverse effect on reproductive performance. All indicators of reproductive performance were improved in varying degrees during breeding, particularly the egg pro-duction at 68 weeks of age. The breeding progress of main target traits significantly slowed down after the second generation, but they still main-tained at higher levels and the characters of S06M tended to be stable. | Qiu Mohan Yang Chaowu Du Huarui Li Qingyun Xiong Xia Zhang Zengrong Hu Chenming Xia Bo Yu Chunlin Song Xiaoyan Yang Li Peng Han Jiang Xiaosong | 2018 | Animal Husbandry and Feed Science2018，10，4： | 0 |
| 10 | Location Privacy in Device-Dependent Location-Based Services:Challenges and Solution显示文摘With the evolution of location-based services(LBS),a new type of LBS has already gain a lot of attention and implementation,we name this kind of LBS as the Device-Dependent LBS(DLBS).In DLBS,the service provider(SP)will not only send the information according to the user’s location,more significant,he also provides a service device which will be carried by the user.DLBS has been successfully practised in some of the large cities around the world,for example,the shared bicycle in Beijing and London.In this paper,we,for the first time,blow the whistle of the new location privacy challenges caused by DLBS,since the service device is enabled to perform the localization without the permission of the user.To conquer these threats,we design a service architecture along with a credit system between DLBS provider and the user.The credit system tie together the DLBS device usability with the curious behaviour upon user’s location privacy,DLBS provider has to sacrifice their revenue in order to gain extra location information of their device.We make the simulation of our proposed scheme and the result convince its effectiveness. | Yuhang Wang Yanbin Sun Shen Su Zhihong Tian Mohan Li Jing Qiu Xianzhi Wang | 2019 | Computers, Materials & Continua2019，，6： | 0 |
| 11 | Comparative Analysis of Slaughter Performance and Meat Flavor Traits of Quality Chicken under Cage Rearing and Free-range Farming Conditions显示文摘[Objective]The paper was to compare the slaughter performance and meat flavor of quality chicken under cage rearing and free-range farming conditions.[Method]A total of 4001-day-old cocks,S07 line cultivated by Sichuan Dahen Poultry Breeding Co.,Ltd.(bred for 4 succes-sive generations),were kept in cages until the end of 5 weeks of age,which were then divided into cage rearing and free-range farming groups.All cocks were fed with the same diet,and slaughter tests and meat quality analysis were carried out at the end of 10 and 22 weeks of age,respectively.[Result]The live weight,carcass weight and abdominal fat percentage in cage rearing group were significantly higher than those in free-range farming group(P<0.01),and the percentage of half-eviscerated yield and percentage of eviscerated yield in cage rearing group were significantly higher than those in free-range farming group(P<0.05),but there were no significant differences in dressing percentage,percentage of leg muscle and per-centage of breast muscle.The intramuscular fat(IMF)content and muscle fiber density of chicken in cage rearing group were significantly higher than those in free-range farming group(P<0.01),but there was no significant difference in inosinic acid(IMP)content.The content of IMF and IMF increased with the increase of feeding age,but the deposition rate of intramuscular fat was higher than that of IMF in late feeding period.[Conclusion]The study will provide reliable guidance for production and market consumption of high quality chicken. | Yang Chaowu Yu Chunlin Qiu Mohan Zhang Zengrong Hu Chenming Xiong Xia Xia Bo Peng Han Song Xiaoyan Chen Jialei Zhu Shiliang Liu Siyang Du Huarui Li Qingyun | 2022 | Animal Husbandry and Feed Science2022，14，1： | 0 |

| 13 | Differentiation of Expression Profiles of SREBF1 and SREBF2 Gene in Chicken显示文摘Sterol regulatory element-binding factor-1 and-2(SREBF1 and SREBF2)are important transcription factors involved in the regulating lipid homeostasis.Based on the essential role of SREBF1 and SREBF2,we measured the mRNA expression levels of the two genes in six various tissues at different growth points.Our results showed that the SREBF1 and SREBF2 were expressed in all six tissues examined in Erlang mountainous chicken(SD02)at 42 d,and were expressed abundantly in the uropygial gland and liver,with relatively lowest levels of expression in the abdominal fat,sebum cutaneum and leg muscle.The expression ratio of SREBF1 and SREBF2 in breast muscle,leg muscle,sebum cutaneum and uropygial gland exhibited a'decline-rise'trend.However,in liver,the expression ratio of these two genes exhibited a'decline-rise-decline'trend.Meanwhile,the expression level of SREBF1 gene of all tissues was lower than that of SREBF2 except for uropygial gland.The findings will provide important references for further function investigation of the two genes involved in fat deposition in chickens. | Mohan QIU Zengrong ZHANG Chunlin YU Xiaosong JIANG Huarui DU Qingyun LI Hengyong XU Huadong YIN Xiaoling ZHAO Qing ZHU Yan WANG Chaowu YANG | 2020 | Agricultural Biotechnology2020，9，5： | 0 |
| 14 | Production Performance of Different Generations of Muchuan Blackbone Chicken显示文摘In order to formulate feasible conservation measures and develop and utilize Muchuan black-bone chicken rationally,two generations of Muchuan black-bone chicken were bred,and their production performance and slaughter traits( at the age of 300 d) were compared. The results showed that the reproductive performance,slaughter performance and body size of the Muchuan black-bone chicken of Generation 1( G_1)were all improved compared with those of the Generation 0( G_0)( P <0. 05). At the age of 300 d,the live weight,carcass weight,and leg muscle weight of the G_1 were significantly higher than those of the G_0( P <0. 05); and the chest width of the cocks of the G_1 was significantly higher than that of the G_0( P <0. 05). It suggests that after rigorous selection and utilization of modern poultry breeding techniques,the reproductive performance,slaughter performance and survival rate of Muchuan black-bone chicken can be improved significantly. | Mohan QIU Zengrong ZHANG Xiaosong JIANG Huarui DU Qingyun LI Chunlin YU Xia XIONG Lihe ZOU Chaowu YANG | 2018 | Asian Agricultural Research2018，10，8： | 0 |
