In ultrasonic imaging systems, the patterns of detected echoes correspond to the shape, size, and orientation of the reflectors and the physical properties of the propagation path. However, these echoes often are overlapped due to closely spaced reflectors and/or microstructure scattering. The decomposition of these echoes is a major and challenging(More)
Manganese superoxide dismutase (MnSOD), glutathione peroxidase-1 (GPX1), and catalase (CAT) provide the primary antioxidant defense system. Impaired antioxidant defense increases oxidative stress and contributes to the development of type 2 diabetes and diabetic cardiovascular disease (CVD). We preformed a case–control study in Chinese type 2 diabetes(More)
—This letter presents a fast chirplet transform (FCT) algorithm, a computationally efficient method, for decomposing highly convoluted signals into a linear expansion of chirplets. The FCT algorithm successively estimates the chirplet parameters in order to represent a broad range of chirplet shapes, including the broadband, narrowband, symmetric, skewed,(More)

Software Defined Radio takes what used to be physically ingrained within the radio and provides a variety of hardware and software alternatives that add to it more flexibility and functionality. This project looks to implement a 16QAM communication system using a baseband receiver and transmitter and two USPR2 boards. It will show the benefits of Software(More)
The aim of this study was to investigate the expression and prognostic significance of NEDD9 in pancreatic ductal adenocarcinoma (PDA). Expressional levels of NEDD9 mRNA and protein in paired pancreatic cancer lesions and adjacent noncancerous tissues were examined by quantitative real-time PCR and western blotting. NEDD9 expression was analyzed by(More)
Pancreatic ductal adenocarcinoma (PDA) is one of the most aggressive malignancies in humans, and its prognosis is generally poor even after surgery. Many advances have been made to understand the pathogenesis of PDA; however, the molecular mechanisms that lead to pancreatic carcinogenesis are still not clearly understood. The aims of this study were to(More)
BACKGROUND Appropriate expression and regulation of the transcriptome, which mainly comprise of mRNAs and lncRNAs, are important for all biological and cellular processes including the physiological activities of bone microvascular endothelial cells (BMECs). Through an intricate intracellular signaling systems, the transcriptome regulates the(More)
