In this paper, we proposed a new architecture of multiplier-and-accumulator (MAC) for high-speed arithmetic.By combining multiplication with accumulation and devising a hybrid type of carry save adder (CSA), the performance was improved. Since the accumulator that has the largest delay in MAC was merged into CSA, the overall performance was elevated. The(More)
Angiogenesis is a key prerequisite for the successful establishment, growth, and dissemination of tumors. Vascular endothelial growth factor (VEGF) has a potent angiogenic activity and cyclooxygenase-2 (COX-2) promotes angiogenesis by modulated production of angiogenic factors including VEGF. The current study was designed to investigate the possible roles(More)
PURPOSE This study was to evaluate the relationship of 25(OH)D3 levels with anticonvulsant use and other possible factors in epileptic children and adolescents. MATERIALS AND METHODS We studied 143 patients with epilepsy (90 boys, 53 girls; 11.21±4.49 years), who had been treated with anticonvulsants for more than 1 year. Patients who had taken multiple(More)
In this paper, we propose a wavelet-based audio watermarking algorithm that is robust against capturing attack. With a commercial capturing tool, it is possible to capture various audio contents without noticeable degradation, and thus can potentially facilitate the illegal distribution of the audio content. By adjusting the mean value of the lowest subband(More)
BACKGROUND Matrix metalloproteinases (MMPs) have been implicated in the remodelling of extracellular matrix (ECM), including basement membrane. ECM remodelling is associated with pathological processes, including hepatic fibrosis, tumor invasion and metastasis. Tissue inhibitors of metalloproteinase (TIMP)-1 and TIMP-2 were known to inhibit MMP-9 and MMP-2,(More)
Widespread popularity of wireless data communication devices, coupled with the availability of higher bandwidths, has led to an increased user demand for content-rich media such as images and videos. Since such content often tends to be either private, sensitive, or paid for, there exists a requirement for securing such communication. However, solutions(More)
BACKGROUND Cyclin-dependent kinase inhibitors (CDKI), including p21, p27 and p57 of the KIP family, are negative regulators of cell cycle progression and potentially act as tumor suppressors. The expression of p21 is induced by tumor suppressor gene p53. Mutations of p53 are common and found in various human cancers. Thus, the function of p21 as a tumor(More)
