We have developed an in vivo transfection method for naked plasmid DNA (pDNA) and siRNA in mice by using a tissue suction device. The target tissue was suctioned by a device made of polydimethylsiloxane (PDMS) following the intravenous injection of naked pDNA or siRNA. Transfection of pDNA encoding luciferase was achieved by the suction of the kidney,(More)
A time-course gene-expression profile was generated for Escherichia coli TK31 when it was exposed to an organic solvent mixture, and classified by fuzzy adaptive resonance theory (Fuzzy ART). It was found that the purR regulon plays an important role in the organic solvent tolerance (OST) of E. coli.
This paper proposes the power-efficient LDPC decoder architecture which features (1) a FIFO buffering based rapid convergence schedule which enables the decoder to accelerate the decoding throughput without increasing the required number of memory bits, (2) an intermediate message compression technique based on a clock gated shift register which reduces the(More)
SUMMARY In this paper, we propose a partially-parallel LDPC de-coder which achieves a high-efficiency message-passing schedule. The proposed LDPC decoder is characterized as follows: (i) The column operations follow the row operations in a pipelined architecture to ensure that the row and column operations are performed concurrently. (ii) The proposed(More)
