A New Image Registration Method for Repeat-Pass InSAR Based on Fourier-Mellin Transformation and Correlation-Coefficient Algorithm

Shi Xiao-jin,Zhang Yun-hua,

电子与信息学报 , 2009,
Abstract: Compared with one pass InSAR system with two antennae, the registration of image pair of repeat-pass InSAR system is much more difficult due to parallel tracks are usually not guaranteed. In this paper, a new image co-registration algorithm for repeat-pass InSAR, which combines the Fourier-Mellin transform and correlation-coefficient algorithm, is proposed to perform accurate co-registration for complex image pair having rotation angle due to unparallel tracks. When the method is used as coarse co-registration step, a nonlinear amplitude transformation is introduced as pre-processing to overcome the failure of Fourier-Mellin transformation method in case of image pair with large dynamic amplitude range and non-uniform amplitude distribution, and when used as fine co-registration step, correlation-coefficient algorithm is incorporated to accurately estimate the small rotation angle between image pair. SIR-C/X X-band experimental data are used to test the proposed algorithm through comparing with traditional correlation-coefficient algorithm in both accuracy and run time. The experimental results prove the effectiveness of the proposed algorithm.

Abstract: Lasers from a Tm:YAG ceramic aare reported for the first time to our best knowledge. The Tm:YAG ceramic slab is end-pumped by a laser diode with central wavelength 792nm. At room temperature, the maximum continuous-wave output power is 4.5W, and the sloping efficiency is obtained to be 20.5%. The laser spectrum of the Tm:YAG ceramic is centered at 2015nm.

Abstract: The fouling mechanisms of membrane in the cross-flow filtration for the slurry Fischer-Tropsch synthesis technology(SFTST) were discussed.The research advances of mathematic modeling in cross-flow filtration for SFTST in literature were reviewed in both three-phase and two-phase systems.Based on different resistances,the models can be divided into blocked resistance,cake resistance and combined resistance.It is supposed that the combined resistance in cross-flow filtration for SFTST will be the further rese...
Generation of Transgenic Mice with Cardiac-specific overexpressing heat shock protein 27

Abstract: Increased reactive oxygen species (ROS) formation and by which in turn promotes cardiomyocytes apoptosis is associated with the pathogenesis and progression of various cardiac diseases. Small heat shock protein 27(Hsp27) could protect different cells from oxidative damage. By using tissue nonspecific overexpression Hsp 27 transgenic model, other investigators demonstrated that Hsp27 suppressed successfully kainate-induced seizures and hippocampal cell death in intact transgenic mice, and attenuated mimic ischemia/reperfusion injury in Langendorff-perfused isolated mice heart. As there are complicated and long distance neuro-humoral regulation associated with the development of cardiac diseases, it is better to choose a cardiac-specific overexpression transgenic model to study the effects of Hsp27 in hearts in vivo.
Research on a Tracking Method and Data Processing for the Runway in Image Sequences of Terminal-sensitive Projectiles

Abstract: A new method of some linear objects tracking such as the runway being changed to tracking of the feature point is presented based on Hough transform during the stable-falling of the sub-muniton. Given all the case of each parameter's decoupling, the parameters of the line in Hough space have been estimated and predicted with the methods of Kalman filtering. In order to establish the relative position between the runway and sub-munition, some modificative processing in equation for predicting the state of objects' contrail are conducted combining some data information of the current image when considering the influence of the detector's spinning with sub-munition. In the instance of small perturbation, a new processing data is established based on the theory of parachute-munition's dynamic analysis in order to obtain the curve of D0 which would ascertain the relative position of sub-munition and runway. All processing data shows that this method has high efficiency and good stability, and reduces the quantity of calculation to some extent. Experiment results show the error of estimation is small and it can meet the general object requirement.

Abstract: Schizochytrium limanium is a kind of marine fungus with high DHA content.In our studies,rotifer Brachionus plicatilis was enriched with S.limanium.The variation of physiology and ecology of rotifer during the experiments was observed and the DHA in rotifer was evaluated.The results showed that: all of the three enriching groups got better results than the control group.DHA content increased obviously and reached the maximum after 12 h enrichment. The max DHA/FA content of the testing groups reached 5.98% 10.21% and 13.44% respectively,and the max DHA content reached 4.42 mg/g 7.85 mg/g and 8.14 mg/g respectively.No DHA was detected in the control group in the whole experiments.Other indexes such as rotifer density,egg-hanging rate in the testing groups were also obviously better than those of the control group.Compared with the egg-hanging rates in the control group,20.1%,the egg-hanging rates in the testing groups had reached 34.8%,46.5% and 53.7% respectively.

Abstract: Background Anti-epidermal growth factor receptor (EGFR) monoclonal antibodies (MoAbs) cetuximab and panitumumab have emerged as an effective targeted therapy in the treatment of cancer patients, but the overall incidence and risk of fatal adverse events (FAEs) associated with these agents is still unclear. Methods Databases from PubMed, Web of Science and abstracts presented at ASCO meeting up to May 31, 2013 were searched to identify relevant studies. Eligible studies included prospective randomized controlled trials evaluating MoAbs in cancer patients with adequate data on FAEs. Statistical analyses were conducted to calculate the summary incidence, odds ratio and 95% confidence intervals (CIs) by using either random effects or fixed effect models according to the heterogeneity of included studies. Results A total of 14,776 patients with a variety of solid tumors from 21 clinical trials were included in our analysis. The overall incidence of MoAbs associated FAEs was 1.7% (95%CI: 1.1–2.5%), and the incidence of cetuximab-related FAEs was higher than that of panitumumab (2.0% versus 0.9%). Compared with the controls, the use of MoAbs was associated with a significantly increased risk of FAEs, with an OR of 1.37 (95%CI: 1.04–1.81, p=0.024). Subgroup analysis based on EGFR-MoAbs drugs, phase of trials and tumor types demonstrated a tendency to increase the risk of FAEs, but the risk did not increase in breast cancer, esophagus cancer and phase II trials. Conclusions With present evidence, the use of EGFR-MoAbs is associated with an increased risk of FAEs in patients with advanced solid tumors.

Abstract: 摘要: 若A是一个Gorenstein代数,则倾斜右A-模的个数等于倾斜左A-模的个数。给出反例说明自内射维数大于等于2的Gorenstein代数B的经典倾斜右B-模的个数不一定等于经典倾斜左B-模的个数。
Abstract: For a Gorenstein algebra A, the number of tilting right A-modules is equal to the number of tilting left A-modules. A counter-example is given to show that for a Gorenstein algebra B with self-injective dimension no less than 2, the number of classical tilting left B-modules is not necessary to be equal to that of classical tilting right B-modules
