| 1 | Back propagation artificial neural network for community Alzheimer's disease screening in China显示文摘Alzheimer's disease patients diagnosed with the Chinese Classification of Mental Disorders diagnostic criteria were selected from the community through on-site sampling. Levels of macro and trace elements were measured in blood samples using an atomic absorption method, and neurotransmitters were measured using a radioimmunoassay method. SPSS 13.0 was used to establish a database, and a back propagation artificial neural network for Alzheimer's disease prediction was simulated using Clementine 12.0 software. With scores of activities of daily living, creatinine, 5-hydroxytryptamine, age, dopamine and aluminum as input variables, the results revealed that the area under the curve in our back propagation artificial neural network was 0.929 (95% confidence interval: 0.868-0.968), sensitivity was 90.00%, specificity was 95.00%, and accuracy was 92.50%. The findings indicated that the results of back propagation artificial neural network established based on the above six variables were satisfactory for screening and diagnosis of Alzheimer's disease in patients selected from the community. | Jun Tang Lei Wu Helang Huang Jiang Feng Yefeng Yuan Yueping Zhou Peng Huang Yan Xu Chao Yu | 2013 | Neural Regeneration Research2013，8，3： | 6 |
| 2 | Review on Additive Manufacturing of Single-Crystal Nickel-based Superalloys显示文摘The conventional fabrication process for single-crystal nickel-based superalloy materials is directional solidifica-tion,which is classified as casting.With the rapid development of additive manufacturing(AM)technologies,a novel process for fabricating single-crystal superalloys has become possible.This article reviews recent research on the AM of single-crystal nickel-based superalloys.Laser AM technologies,particularly directed energy deposition,are mainly used to repair single-crystal materials.Electron beam powder bed fusion is an innovative method for the direct fabrication of single-crystal materials.Accordingly,the mechanisms of single-crystal formation during AM are analyzed to elucidate the potential of this process route.Furthermore,this article discusses the challenges faced by AM for single-crystal fabrication,and provides perspectives on the trends of future developments. | Yang Li Xiaoyu Liang Yefeng Yu Dongfang Wang Feng Lin | 2022 | Chinese Journal of Mechanical Engineering(Additive Manufacturing Frontiers)2022，1，1： | 2 |

| 4 | Effects of S-adenosylmethionine on production of secondary metabolites in Streptomyces diastatochromogenes 1628显示文摘Streptomyces are famous for their ability to synthesize a large number of bioactive compounds as secondary metabolites containing antibiotics,enzyme inhibi-tors,and other small molecules with potential physiological activity(Niu et al.,2016;Song et al.,2019;Yin et al.,2019).Secondary metabolites are produced by a multi-step reaction of a primary metabolite as a precursor(Liu et al.,2013;Li et al.,2021).Therefore,it is of great research significance to increase the overall synthesis level of antibiotics by increasing the amount of synthesis of precursors. | Yefeng HU Juan WANG Jie XU Zheng MA Andreas BECHTHOLD Xiaoping YU | 2021 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2021，22，9： | 0 |
| 5 | Unevenly distributed LED light produces distinct behavioral preferences and production performance of broilers显示文摘LED has shown great advantages in poultry husbandry.This study focused on the behavioral preferences and production performance of chicken broilers reared under unevenly distributed yellow LED light.Four pens were divided into two groups adopting respective maximum light intensities(MLIs,60 lx and 30 lx).Because of different distances from the installation position of the LED pipe,each pen was distributed with unevenly distributed light.Each pen consisted of four subzones indicated by their light intensities-high intensity(HI),medium intensity(MI),low intensity(LI)and weak intensity(WI).Four subzones were the same size and provided with a feeder and a drinker,respectively.The broilers moved freely across the four subzones.No significant differences in body weight(BW),uniformity of final BW and feed conversion ratio(FCR)were observed between the two experimental groups.However,greater feed intake and water intake were found in HI than those in other subzones.The drinking preference changed with age for four subzones and was more likely to appear at the later stage,despite substantial fluctuations within the replicates.The feeding preference was more constant than the drinking preference and appeared mainly at the early and middle stages of this study.These findings could provide implications for broiler production reared under unevenly distributed LED light condition. | Chenghao Pan Minsi Lu Yingping Zhang Yue Yu Qiuyan Lu Yefeng Yang Jinming Pan | 2019 | International Journal of Agricultural and Biological Engineering2019，12，2： | 0 |
