Based on the study of motion vector distribution from several commonly used test image sequences, a new diamond search (DS) algorithm for fast block-matching motion estimation (BMME) is proposed in this paper. Simulation results demonstrate that the proposed DS algorithm greatly outperforms the well-known three-step search (TSS) algorithm. Compared with the(More)
Increasing evidence suggests the important role of metabolic reprogramming in the regulation of the innate inflammatory response, but the underlying mechanism remains unclear. Here we provide evidence to support a novel role for the pyruvate kinase M2 (PKM2)-mediated Warburg effect, namely aerobic glycolysis, in the regulation of high-mobility group box 1(More)
The paper presents an extension of content based image retrieval (CBIR) techniques based on Overlap Modified Block Truncation Coding (BTC) and Overlap Gabor Magnitude. Modified Block truncation coding based features is one of the CBIR methods proposed using color features of image. The approach basically considers red, green and blue planes of an image to
Multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) has attracted much attention as a solution of high-quality service for next generation wireless communications. However, like OFDM, one of main problems of MIMO-OFDM is the high peak-to-average power ratio (PAPR). In this paper, a novel method to reduce the MIMO-OFDM(More)
IFN1@ (interferon, type 1, cluster, also called IFNα) has been extensively studied as a treatment for patients with chronic myeloid leukemia (CML). The mechanism of anticancer activity of IFN1@ is complex and not well understood. Here, we demonstrate that autophagy, a mechanism of cellular homeostasis for the removal of dysfunctional organelles and(More)
One of the major disadvantage of OFDM is the high peak-to-average power ratio (PAPR) of the transmitted OFDM signal. This paper proofed the autocorrelation properties of CAZAC sequence, and then proposed a new method to reduce the PAPR in OFDM systems based on CAZAC sequence by taking advantage of the low autocorrelation characteristics of CAZAC sequence(More)
