Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809013373
Abstract: In the molecule of the title compound, C16H12N2O4, the pyridine ring is oriented at the same dihedral angle of 2.92 (3)° with respect to the furan and isoxazole rings, while the dihedral angle between furan and isoxazole rings is 1.34 (3)°. The dihedral angle between the benzene and pyridine rings is 53.23 (3)°. In the crystal structure, intermolecular C—H...O interactions link the molecules into chains. Weak π–π contacts between isoxazole and benzene rings [centroid–centroid distance = 3.969 (3) ] may further stabilize the structure.
A Complete Solution for Dissecting Pure Main and Epistatic Effects of QTL in Triple Testcross Design
Xiao-Hong He, Yuan-Ming Zhang
PLOS ONE , 2011, DOI: 10.1371/journal.pone.0024575
Abstract: Epistasis plays an important role in genetics, evolution and crop breeding. To detect the epistasis, triple test cross (TTC) design had been developed several decades ago. Classical procedures for the TTC design use only linear transformations Z1, Z2 and Z3, calculated from the TTC family means of quantitative trait, to infer the nature of the collective additive, dominance and epistatic effects of all the genes. Although several quantitative trait loci (QTL) mapping approaches in the TTC design have been developed, these approaches do not provide a complete solution for dissecting pure main and epistatic effects. In this study, therefore, we developed a two-step approach to estimate all pure main and epistatic effects in the F2-based TTC design under the F2 and F∞ metric models. In the first step, with Z1 and Z2 the augmented main and epistatic effects in the full genetic model that simultaneously considered all putative QTL on the whole genome were estimated using empirical Bayes approach, and with Z3 three pure epistatic effects were obtained using two-dimensional genome scans. In the second step, the three pure epistatic effects obtained in the first step were integrated with the augmented epistatic and main effects for the further estimation of all other pure effects. A series of Monte Carlo simulation experiments has been carried out to confirm the proposed method. The results from simulation experiments show that: 1) the newly defined genetic parameters could be rightly identified with satisfactory statistical power and precision; 2) the F2-based TTC design was superior to the F2 and F2:3 designs; 3) with Z1 and Z2 the statistical powers for the detection of augmented epistatic effects were substantively affected by the signs of pure epistatic effects; and 4) with Z3 the estimation of pure epistatic effects required large sample size and family replication number. The extension of the proposed method in this study to other base populations was further discussed.

Abstract: The existence of the very theory concerned about the object of civil litigation, which is one of the fundamental theories of civil procedure law, has been of great value in the following two respects. Firstly, it should provide the guidelines for the judges as to define the scope of the lawsuits, as well as the target and the field of the claims battled or defended by one party against another party under the particular dispute. Secondly, it determines the territorial of Res judicada, where the valid judgment can be complied by the parties. In order to fully realize the above two items of value of the theory, it is of importance to efficiently clarify the discernment criterion of the object of litigation, and appropriately resolve the crisis of defining such criterion, raised by the result of the overlapping state among the substantial rights of civil petition. Meanwhile, such solution is happened to be the core challenge of the continuance academic argument on the theory of the object of civil litigation, which needs to be resolved necessarily in the area of the civil litigation procedure law. Resolving this core challenge problem, on the basis of the nature of the substantial rights of civil petition and the purpose of civil litigation, it needs to clarify the object of litigation as the whole content of the claim of litigation based on the claims of particular substantial natural fact, and regards the claim of litigation as the main discernment criterion of the object of litigation in the assistance of the claims of substantial natural fact by the plaintiff if necessarily. About this article, it starts from describing the source of the concept of object of litigation and the issues needed to settle to realize the value of object of litigation. Subsequently, the author analyzes the research state of the discernment criterion of object of litigation in some foreign countries. Lastly, the author comments the theory of object of litigation under China law. Meanwhile, the author analyzes the discernment issue of the object of litigation in new way when petition rights are combined.

Abstract: An easy and general way to access more complex soliton phenomena is introduced in this paper. The collision process between two solitons of the KdV equation is investigated in great detail with this novel approach, which is different from the sophisticated method of inverse scattering transformation. A more physical and transparent picture describing the collision of solitons is presented.

PIER B , 2010, DOI: 10.2528/PIERB10012401
Abstract: Intelligent compression is important to image transmission in real time over bandlimited channels for synthetic aperture radar (SAR) payloads deployed on unmanned aerial vehicles (UAV), where target areas are encoded with high fidelity, while background data are encoded with lesser fidelity. A target-aided SAR image intelligent compression (TAIC)system is presented in this paper, which utilizes robust fixed-rate trellis-coded quantization (FRTCQ) to encode target sequences and FRTCQ to encode background sequences. Multiresolution constant false alarm rate (CFAR) detector in wavelet domain using db4 based on the multiscale model of target is embedded. Generic region of interest (ROI) mask is created. In order to achieve better quality of target areas decoded, ROI mask is modified. The improved performance using TAIC system by compressing target chips from training set and testing set in Moving and Stationary Target Acquisition and Recognition (MSTAR) database is demonstrated.

Abstract: Variety of detected features and complexity of similarity calculation are two main problems in image registration. In this paper, angle histogram and alignment metric of edge feature points are defined, and a new approach for image registration is presented based on alignment metric of edge feature points. The first step is to detected edge image and feature points by using wavelet multi-scale product. In this step, wavelet multi-scale product can ensure the accuracy of edge image and feature points. The second step is to calculate alignment metric of feature points based on rotating angle obtained from angle histogram. Then mapping points can be accurately determined by an appropriate threshold. The calculation complexity of alignment metric is greatly simplified since the process is based on edge images. Several experiments conducted illustrate that this method have a good performance of robust, accuracy and efficiency, and also it can be applied to many situations.

Abstract: In this paper,a noval second generation watermarking algorithm based on image corner feature is proposed.Firstly, the watermark image is scrambled by using Arnold transformation. Secondly, wavelet transformation based three-level lifting for the carrier image is conducted. Thirdly, utilized the outcome of second step and MSP method, corners are detected from the low frequency components. Finally, by taking corners as root nodes, all the corresponding high frequency coefficients are extracted. Inverse operation of embedding watermark is performed with those coefficients. And using the given key, the watermark can be obtained. Sufficient experiments demonstrate the robustness of this approach, especially in resisting geometry attack such as RST (Rotation, Scaling and translation)and cut attack.

Abstract: A coupled meteorology and aerosol/chemistry model WRF-Chem (Weather Research and Forecast model coupled with Chemistry) was used to conduct a pair of simulations with present-day (PD) and preindustrial (PI) emissions over East Asia to examine the aerosol indirect effect on clouds. As a result of an increase in aerosols in January, the cloud droplet number increased by 650 cm-3 over the ocean and East China, 400 cm-3 over Central and Southwest China, and less than 200 cm-3 over North China. The cloud liquid water path (LWP) increased by 40-60 g m-2 over the ocean and Southeast China and 30 g m-2 over Central China; the LWP increased less than 5 g m-2 or decreased by 5 g m-2 over North China. The effective radius (Re) decreased by more than 4 mm over Southwest, Central, and Southeast China and 2 mm over North China. In July, variations in cloud properties were more uniform; the cloud droplet number increased by approximately 250-400 cm-3, the LWP increased by approximately 30-50 g m-2, and Re decreased by approximately 3 mm over most regions of China. In response to cloud property changes from PI to PD, shortwave (SW) cloud radiative forcing strengthened by 30 W m-2 over the ocean and 10 W m-2 over Southeast China, and it weakened slightly by approximately 2-10 W m-2 over Central and Southwest China in January. In July, SW cloud radiative forcing strengthened by 15 W m-2 over Southeast and North China and weakened by 10 W m-2 over Central China. The different responses of SW cloud radiative forcing in different regions was related to cloud feedbacks and natural variability.

Abstract: Fuzzy C-means(FCM) clustering algorithm was an effective image segmentation algorithm which combined the concept of fuzzy sets and unsupervised clustering. And it suited for the uncertain and ambiguous characteristic in intensity image. But it was sensitive to initial clustering center and membership matrix and likely converged into the local minimum, which caused the quality of image segmentation lower. By using of the properties-ergodicity, randomicity of chaos, this paper proposed a new image segmentation algorithm, which combined the chaos particle swarm optimization(CPSO) and FCM clustering. Experimental results prove this method not only has the ability to prevent the particles to convergence to local optimum because of standstill, but also has faster convergence and higher accuracy of segmentation.
