| 1 | Construction of precise support vector machine based models for predicting promoter strength显示文摘原核生物的倡导者力量的预言不仅在生命科学的基本研究而且在合成生物学的应用方面基于它的顺序是很重要的。许多进展被做了为力量预言造量的模型,特别象人工的神经网络(ANN ) 那样的机器学习方法的介绍显著地有改进预言精确性。作为最重要的机器学习方法之一,支持向量机器(SVM ) 是更强大的听说从小样品数据集并且这样的知识想了处于这个问题工作。证实这的方法,我们构造了基于的 SVM 到份量上的模型预言倡导者力量。100 个倡导者序列和力量价值的一个图书馆随机被划分成二数据集,包括为模型训练和为模型测试的一个测试集合(10 个序列) 的一个训练集合(10 个序列) 。结果显示的结果有训练的尺寸的增加的预言表演增加设定,并且最好的表演在 90 的尺寸被完成,这定序。在模型参数的优化以后,一个高效的模型最后被训练,与为适合训练集合的一个高摆平的关联系数( R 2> 0.99 )并且测试集合( R 2> 0.98 ),哪个比我们的以前的工作获得的 ANN 的好。我们的结果表明基于 SVM 的模型的结论能为倡导者力量的量的预言被采用。 | Hailin Meng Yingfei Ma Guoqin Mai Yong Wang Chenli Liu | 2017 | Frontiers of Electrical and Electronic Engineering in China2017，5，1： | 2 |
| 2 | Numerical Simulation of Float-Over Installation for Offshore Platform显示文摘In this paper,a numerical investigation of a float-over installation for an offshore platform is presented to verify the feasibility of the actual installation.The hydrodynamic performance of a T-barge is investigated in the frequency domain,and the coupled motions are analyzed in the time domain.We then compare with those of the model test and determine that the response amplitude operator and the time series agree quite well.The barge exhibits favorable hydrodynamic behavior in the considered sea state,and the equipment loads are allowable.Themooring systemand sway fender forces are within the permissible range.Based on these results,we can verify that the actual installation of the offshore platform is feasible.We accurately simulated many important factors and effectively reduced the risk associated with the offshore installation,which is of great importance.As such,we demonstrate that the numerical simulation of the float-over installation for offshore platforms has practical engineering significance. | Yuesheng Ma Lihao Yuan Yingfei Zan Fuxiang Huang | 2018 | Journal of Marine Science and Application2018，17，1： | 1 |
| 3 | Fabrication of bulk glassy Zr_(41)Ti_(14)Ni_8Cu_(12.5)Be_(22.5)Fe_2 alloy by water quenching显示文摘A glassy Zr41Ti14Ni8Cu12.5Be22.5Fe2 rod with a diameter of 9 mm was successfully pro-duced by water puenching. The effects of iron addition on thermal stability and hardness of Zr41Ti14Ni8Cu12.5Be22.5Fe2 bulk amorphous alloy were investigated by XR D, DSC and microhardness test. it is found 1that the full annealing would enhance the strength of the alloy significantly. The cause of the increase in hardness was analyzed and the formation mechanisms of the bulk amorphous alloy are discussed. | Jl Yingfei, Jl Gang, XIAO Xueshan, DONG Yuanda, MA Xueming WANG Weihua & ZHAO Deqian1.

| 4 | Elucidating the electronic metal-support interaction enhanced hydrogen evolution activity on Ti_(3)C_(2)T_(x)MXene basal plane by scanning electrochemical microscopy显示文摘MXene,a family of two-dimensional(2D)transition metal carbides and nitrides,has intriguing electrochemical energy storage and electrocatalysis applications.Introducing the electronic metal-support interaction(EMSI)effect is one effective strategy to optimize the catalytic efficiency for MXene-based composites.However,most of the studies concentrate on optimizing the performance of metals rather than supported substrates by using this strategy.In this work,we mainly investigate the influence of an EMSI effect on the performance of the supported substrate(Ti_(3)C_(2)T_(x)MXene).Detailed scanning electrochemical microscopy and numerical simulations results reveal that the charge distribution on the Ti_(3)C_(2)T_(x)basal plane(approximate 100 nm-radius)surrounding Au nanoparticles(20 nm-radius)was significantly enhanced as a result of-O being the majority surface functional group on Ti_(3)C_(2)T_(x)that was attached to Au nanoparticle,and the related hydrogen evolution reaction(HER)activity was much better than that of the unaffected Ti_(3)C_(2)T_(x)basal plane,which even can be comparable to that of Au.This finding will be helpful for designing new strategies to enhance the overall catalytic performance of various MXene-based composites. | Sisi Jiang Tong Sun Chaoqun Gu Yingfei Ma Zhenyu Wang Dengchao Wang Zonghua Wang | 2023 | Nano Research2023，16，7： | 0 |
