In the title molecule, C11H9N3O2S, the pyridine and pyrimidine rings are almost parallel [dihedral angle = 6.7 (1)°]. In the crystal, adjacent molecules are joined by O—H...N and C—H...O hydrogen bonds, leading to the formation of a sheet parallel to (10overline{2}).

Abstract:
A valid unsupervised and multiscale segmentation of synthetic aperture radar(SAR) imagery is proposed by a combination GA-EM of the Expectation Maximization(EM) algorith with the genetic algorithm (GA). The mixture multiscale autoregressive(MMAR) model is introduced to characterize and exploit the scale-to-scale statisticalvariations and statistical variations in the same scale in SAR imagery due to radar speckle,and a segmentation method is given by combining the GA algorithm with the EMalgorithm. This algorithm is capable of selecting the number of components of the modelusing the minimum description length (MDL) criterion. Our approach benefits from theproperties of the Genetic and the EM algorithm by combination of both into a singleprocedure. The population-based stochastic search of the genetic algorithm (GA) exploresthe search space more thoroughly than the EM method. Therefore, our algorithm enablesescaping from local optimal solutions since the algorithm becomes less sensitive to itsinitialization. Some experiment results are given based on our proposed approach, andcompared to that of the EM algorithms. The experiments on the SAR images show that theGA-EM outperforms the EM method.

Abstract:
Dexing copper mine, which lies in the northeastern Jiangxi Province, China, is one of the largest copper mine in Asia. No.1 mine tailings pond was abandoned in 1987, which resulted in a 210 hm 2 pond requiring stabilization with water cover. Mine tailings pond is of environmental concern for potential hazards in surface and groundwater, which may be uptake by vegetation and bioaccumulation in food chains. Diversity of landscape and stability of tailings is important to remain the manmade reservoir. The met...

Abstract:
In the title compound, C22H15N3O6, the central benzene ring and one of the phenyl rings are essentially parallel to each other, making a dihedral angle of 1.35 (16)°. The dihedral angle between the two phenyl rings is 83.56 (19)°. Intramolecular C—H...N and C—H...O hydrogen bonds occur. In the crystal, molecules are linked through C—H...O hydrogen bonds. Furthermore, offset face-to-face π–π interactions with centroid–centroid distances of 3.644 (2) help to stabilize the crystal structure.

Abstract:
There are two independent molecules in the asymmetric unit of the title compound, C9H14N2O2S. In the crystal, the molecules are linked by N—H...O hydrogen bonds, forming a chain along the a axis.
