In this paper, we propose a novel fair transaction protocol based on electronic cash. With the extension of untraceable electronic cash, we have designed a fair transaction protocol to satisfy both the anonymity and the fairness properties simultaneously. Under the existence of an off-line trusted third party (FTP), the protocol is efficient and practical.(More)
Since the topology of neural networks is very crucial to the performance, the reconfigurable ability of the neural network hardware is very important. Therefore, this paper proposes an efficient architecture to implement the reconfigurable back propagation based neural network (BPNN). To further reduce the hardware, this paper adopts the resource sharing(More)
This study investigated the potential effects of natural products ursolic acid (UA) and oleanolic acid (OA) against HBx-mediated tumorigenic activities in vitro and in vivo. HBx transactivated Sp-1 and Smad 3/4 in Huh7 and FL83B hepatocytes and induced cell migration of Huh7 and HepG2. HBx also induced MMP-3 secretion in Huh7 and acted against TGF-β-induced(More)
Invertebrates rely on an innate immune system to combat invading pathogens. The system is initiated in the presence of cell wall components from microbes like lipopolysaccharide (LPS), β-1,3-glucan (βG) and peptidoglycan (PG), altogether known as pathogen-associated molecular patterns (PAMPs), via a recognition of pattern recognition protein (PRP) or(More)
