About 1000 d after the SRT, the X-ray luminosity of the associated pulsar wind nebula (PWN) was found to brighten by $32\pm 8{{\ \rm per\ cent}}$. After the SRT, the braking index n of PSR B0540-69 changes from n = 2.12 to 0.03 and then keeps this value for about five years before rising to n = 0.9 in the following years. We find that most of the current models have difficulties in explaining the measured braking index. One exceptive model of the braking index evolution is the increasing dipole magnetic field of PSR B0540-69. We suggest that the field increase may result from some instabilities within the pulsar core that enhance the poloidal component at the price of toroidal component of the magnetic field. The increasing dipole magnetic field will result in the X-ray brightening of the PWN. We fit the PWN X-ray light curve by two models: one assumes a constant magnetic field within the PWN during the brightening and the other assumes an enhanced magnetic field proportional to the energy density of the PWN. It appears that the two models fit the data well, though the later model seems to fit the data a bit better. This provides marginal observational evidence that magnetic field in the PWN is generated by the termination shock. Future high-quality and high-cadence data are required to draw a solid conclusion.   Integrated thermal assembly using hierarchical kernel regression method 期刊论文  OAI收割 ADVANCED ROBOTICS, 2019, 页码: 15 作者:     |  收藏  |  浏览/下载：89/0  |  提交时间：2019/12/16 Hierarchical kernel regression  integration thermal assembly model  interference-fit   Heteroscedastic and symmetric efficiency for hydrological model evaluation criteria 期刊论文  OAI收割 HYDROLOGY RESEARCH, 2019, 卷号: 50, 期号: 5, 页码: 1189-1201 作者:  Zhan, Chesheng;  Han, Jian;  Zou, Lei;  Sun, Fubao;  Wang, Tiejun   |  收藏  |  浏览/下载：64/0  |  提交时间：2020/05/19 conceptual hydrological model  goodness of fit  heteroscedasticity  metric space  model performance assessment   Heteroscedastic and symmetric efficiency for hydrological model evaluation criteria 期刊论文  OAI收割 HYDROLOGY RESEARCH, 2019, 卷号: 50, 期号: 5, 页码: 1189-1201 作者:  Zhan, Chesheng;  Han, Jian;  Zou, Lei;  Sun, Fubao;  Wang, Tiejun   |  收藏  |  浏览/下载：15/0  |  提交时间：2020/05/19 conceptual hydrological model  goodness of fit  heteroscedasticity  metric space  model performance assessment   射电脉冲星参数拟合的一般方法 会议论文  OAI收割 山东烟台, 42614 作者:  王娜;  刘志勇;  袁建平;  王晶波;  何大林   |  收藏  |  浏览/下载：44/0  |  提交时间：2018/01/24 脉冲星  参数  计时模型  拟合  到达时间  星历表  Pulsar  Timing Model  Time Of Arrival  Parameter  Fit  Ephemerides   Exploring the Dynamic Functional Landscape of Adenylate Kinase Modulated by Substrates 期刊论文  OAI收割 journal of chemical theory and computation, 2013, 卷号: 9, 期号: 1, 页码: 84-95 Wang Y; Gan LF; Wang EK; Wang J 收藏  |  浏览/下载：28/0  |  提交时间：2014/04/18 CONFORMATIONAL TRANSITIONS  ENERGY LANDSCAPE  INDUCED-FIT  ESCHERICHIA-COLI  MOLECULAR-DYNAMICS  LIGAND-BINDING  DOMAIN CLOSURE  NETWORK MODEL  PROTEIN  MECHANISM   Application of trend extrapolation method to spectrum analysis of microtremor signal (EI CONFERENCE) 会议论文  OAI收割 2nd World Congress on Computer Science and Information Engineering, CSIE 2011, June 17, 2011 - June 19, 2011, Changchun, China Zhou X.; Guo T.; Jiao J. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 The trend extrapolation method is applied to spectrum analysis of microtremor signal in order to increase the spectral estimation accuracy. First  establish an appropriate extrapolation model based on the existing data series  and then fit correlation functions other than existing data by derivative least squares method  finally perform spectrum analysis using extrapolated correlation functions. Numerical simulations and the experimental results show that good results are achieved no matter correlation functions change slow or rapid  and the extrapolation error is not more than 2.3%. 2012 Springer-Verlag Berlin Heidelberg.   Features extraction and matching of teeth image based on the SIFT algorithm (EI CONFERENCE) 会议论文  OAI收割 2012 2nd International Conference on Computer Application and System Modeling, ICCASM 2012, July 27, 2012 - July 29, 2012, Shenyang, China 作者:  Wang X.;  Wang X.;  Wang X. 收藏  |  浏览/下载：28/0  |  提交时间：2013/03/25 Using of SIFT algorithm in the image of teeth model  can detect the features of the teeth image effectively. In this approach  first  search over all scales and image locations by using a difference-of-Gaussian function to identify potential interest points that are invariant to scale and orientation. Second  select keypoints based on measures of their stability and a detailed model is fit to determine location and scale at each candidate location. Third  assign one or more orientations to each keypoint location based on local image gradient directions. Last  measure the local image gradients at the selected scale in the region around each keypoint. And then use the KNN algorithm to match the features. Through lots of experiments and comparing with other feature extraction methods  this method can detect the features of the teeth model effectively  and offer some available parameters for 3D reconstruction of the teeth model. the authors.
