This paper presents the quantitative analysis of signal-to-noise ratio (SNR) for the local polynomial Fourier transform (LPFT) used for application of inverse synthetic aperture radar (ISAR) imaging. The relationship between the LPFT and Wigner-Ville distribution (WVD) is derived and theoretical analysis on the SNR achieved by using the LPFT is given.(More)
The multifunctional RNA-binding protein CUGBP1 regulates multiple aspects of nuclear and cytoplasmic messenger RNA (mRNA) processing, including splicing, stabilization, and translation of mRNAs. Previous studies have shown that CUGBP1 is overexpressed in non-small-cell lung cancer (NSCLC) tissues, but the pathological functions of CUGBP1 in tumorigenesis(More)
Robust detection and estimation of frequency-modulated signals and extraction of modulation parameters are of great interest for intelligent telecommunication applications. This paper presents the time-frequency analysis based robust detection, classification and parameter estimation of linear frequency modulated signals and FSK signals in a blind(More)
In this paper, we show that there are a number of uncertainty principles for the local polynomial Fourier transform and local polynomial periodogram. Systematic analysis of uncertainty principles is given, explicit expressions of the uncertainty relations are derived, and an example using the chirp signal and the Gaussian window function is given to verify(More)
This paper presents the combination of the local polynomial Fourier transform and the Hough transform to detect chirp signals. By considering the improvement on the signal to noise ratio, the performance of the proposed combination can achieve significant performance improvement compared to the Wigner-Hough transform. Simulation results are also presented(More)
Nesfatin-1 is an important molecule in the regulation of reproduction. However, its role in the reproductive axis in male animals remains to be understood. Here, we found that nesfatin-1 was mainly distributed in the arcuate nucleus (ARC), paraventricular nucleus (PVN), periventricular nucleus (PeN), and lateral hypothalamic area (LHA) of the hypothalamus;(More)
Guiding non-neural, retinal pigment epithelium (RPE) to produce retinal neurons may offer a source of developing neurons for cell-replacement. Sox2 plays important roles in maintaining neural progenitor/stem cell properties and in converting fibroblasts into pluripotent stem cells. This study tests the possibility of using Sox2 to reprogram RPE to(More)
Essential hypertension (EH) is a complex disease as a consequence of interaction between environmental factors and genetic background, but the pathogenesis of EH remains elusive. The emerging tools of network medicine offer a platform to explore a complex disease at system level. In this study, we aimed to identify the key proteins and the biological(More)
