We recently reported that Phenethyl caffeate benzoxanthene lignan (PCBL), a semisynthetic compound derived from Caffeic Acid Phenethyl Ester (CAPE), induces DNA damage and apoptosis in tumor cells. In this study, we further investigated whether PCBL induces autophagy in WiDr cells. We also analyzed the pathways regulating autophagy and the role of autophagy(More)
This paper proposes an area efficient and low power Reed-Solomon (RS) decoder. The proposed decoder is designed using eight stage arithmetic pipelined architecture. The pipelined architecture of RS decoder performs the detection of error locator from the input stream and computes the error magnitude polynomial using the Berleykamp Massey's algorithm. The(More)
Variable Block Size (VBS) motion estimation has been adopted by H.264/AVC for its compression efficiency and high video quality. In this paper we propose parallel 2-D architecture for computing the Motion Vectors (MV). This 2-D systolic array architecture is composed of 16 Processing Element (PE) with Carry Save Adder (CSA) compressor and comparators to(More)
Video coding is used for lot of multimedia purposes like video conferencing, digital storage media, Internet streaming and television broadcasting. This paper presents a new design for the implementation of Full-Search (FS) Variable Block Size (VBS) Motion Estimation (ME), which is a key issue of different video compression standards such as MPEG-1, MPEG-2,(More)
