The problem of underdetermined blind source separation of adjacent satellite interference is proposed in this paper. Density Clustering algorithm(DC-algorithm) presented in this article is different from traditional methods. Sparseness representation has been applied in underdetermined blind signal source separation. However, some difficulties have not been considered, such as the number of sources is unknown or the mixed matrix is ill-conditioned. In order to find out the number of the mixed signals, Short Time Fourier Transform(STFT) is employed to segment received mixtures. Then, we formulate the blind source signal as cluster problem. Furthermore, we construct Cost Function Pair and Decision Coordinate System by using density clustering. At the end of this paper, we discuss the performance of the proposed method and verify the novel method based on several simulations. We verify the proposed method on numerical experiments with real signal transmission, which demonstrates the validity of the proposed method. 展开更多

We describe a new species in the snakefly family Inocelliidae from Guizhou,China,namely Inocellia wenii sp.nov.This new species can be assigned to the Inocellia crassicornis species-group based on the male gonocoxite 9 wider than long.It mostly resembles Inocellia shinohara Aspock,Liu&Aspock,2009that is endemic to Taiwan,but can be distinguished from the latter species by the male gonapophyses 9proximally with a pair of subtriangular sclerotized lobes that are associated with the endophallus.The present finding represents the second snakefly species recorded from Guizhou.A key to species of the I.crassicornis group is presented. 展开更多

In this essay I will explicate the gaze (le regard) and the ways in which it exceeds or transcends what we know as vision, the objectifying or representational power of the eyes. Building critically on Sartre, the gaze in Lacan and Merleau-Ponty is part of the technical apparatus used to describe the foundation, production, and reproduction of the subject. I will begin by discussing the role of visual perception in subject-formation in their respective work, differentiating between the Merleau-Pontian notion of the "gaze of the world," i.e., the ways in which things cast their gaze upon us, and the Lacanian gaze as a manifestation of the scopic drive. Through an analysis of anamorphosis I will show (1) how the gaze evades the spectator, (2) what the relationship of the gaze is to the object petit a as the object of the scopic drive, and (3) how both Merleau-Ponty and Lacan require a movement that precedes and destabilizes the subject of intentional consciousness. 展开更多

Instead of independent component analysis (ICA),SCA can be used to solve underdetermined mixture efficiently. Two-step approach (TSA) is one of the typical methods to solve SCA based BSS problems. It estimates the mixing matrix before the separation of the sources. K-means clustering is often used to estimate the mixing matrix. It relies on the prior knowledge of the source number strongly. However,the estimation of the source number is an obstacle. In this paper,a fuzzy clustering method is proposed to estimate the source number and mixing matrix simultaneously. After that,the sources are recovered by the shortest path method (SPM). Simulations show the availability and robustness of the proposed method. 展开更多

The green mirid bug Apolygus lucorum is an agricultural pest that is known to cause damage to more than 150 plant species. Here, we report the transcriptomes ofA. lucorum at three different developmental stages (the second and fifth instar nymphs and adults). A total of 98,236 unigenes with an average length of 1,335nt was obtained, of which 50,640 were annotated, including those encoding digestive enzymes and cytochrome P450s. Comparisons with cotton bollworm and cotton aphid transcriptomes revealed distinct features ofA. lucorum as a mesophyll feeder. The gene expression dynamics varied during development from young nymphs to adults. The high-quality transcriptome data and the gene expression dynamics reported here provide valuable data for a more comprehensive understanding of the physiology and development of mirid bugs, and for mining targets for their control. 展开更多
