New design and optimization of charge pump rectifiers using diode-connected MOS transistors is presented in this paper. An analysis of the output voltage and Power Conversion Efficiency (PCE) is given to guide and evaluate the new design. A novel diode-connected MOS transistor for UHF rectifiers is presented and optimized, and a high efficiency N-stage(More)
Radio Frequency Identification (RFID) is an important technique for wireless sensor networks and the Internet of Things. Recently, considerable research has been performed in the combination of public key cryptography and RFID. In this paper, an efficient architecture of Elliptic Curve Cryptography (ECC) Processor for RFID tag chip is presented. We adopt a(More)
The de®nition and maintenance of work¯ow processes have become important tasks for enterprises as work¯ow management systems (WFMS) are systematically applied to critical business processes. In order to simplify the management and usage of work¯ow processes and to integrate with other applications, a good modeling method is essential. The WFCP-net(More)
BACKGROUND DNA-methyltransferase (DNMT)-3A plays an important role in the development of embryogenesis and the generation of aberrant methylation in carcinogenesis. The aim of this study was to investigate the role of a DNMT3A promoter genetic variant on its transcriptional activity and to evaluate the association between DNMT3A gene polymorphism and the(More)
BACKGROUND DNA-methyltransferase-3B (DNMT3B), which plays a role in DNA methylation, is usually aberrant expression involved in carcinogenesis. Polymorphisms of the DNMT3B gene may influence DNMT3B activity on DNA methylation in several cancers, thereby modulating the susceptibility to cancer. METHODS DNMT3B -579G>T genotypes and -149C>T were determined(More)
SUMMARY Fault diagnosis of analog circuits is essential for analog and mixed-signal systems testing and maintenance. A new method is proposed in this paper for multiple fault diagnosis of linear analog circuits in frequency domain. Woodbury formula is applied to the modified nodal equation to construct the fault diagnosis equation, which relates the limited(More)
—Association rules mining is an important content in data mining. It can discover the relations of different attributes by analyzing and disposing data which is in database. This paper proposes a novel data mining algorithm to enhance the capability of exploring valuable information from databases with continuous values. The algorithm combines with(More)
