Ternary Full Adder Using Multi-Threshold Voltage Graphene Barristors
IEEE Electron Device Letters, 2018Co-Authors: Seokhyeong KangAbstract:Ternary logic circuit has been studied for several decades because it can provide simpler circuits and subsequently lower power consumption via succinct interconnects. We demonstrated a ternary full adder exhibiting a low power-delay-product of ~10-16 J, which is comparable to the Binary Equivalent circuit. The ternary full adder was modeled using device parameters extracted from the experimentally demonstrated multi-Vth ternary graphene barristors.

MiRDeep*: An integrated application tool for miRNA identification from RNA sequencing data
Nucleic Acids Research, 2013Co-Authors: Jiyuan An, John Lai, Melanie L. Lehman, Colleen C NelsonAbstract:miRDeep and its varieties are widely used to quantify known and novel micro RNA (miRNA) from small RNA sequencing (RNAseq). This article describes miRDeep*, our integrated miRNA identification tool, which is modeled off miRDeep, but the precision of detecting novel miRNAs is improved by introducing new strategies to identify precursor miRNAs. miRDeep* has a user-friendly graphic interface and accepts raw data in FastQ and Sequence Alignment Map (SAM) or the Binary Equivalent (BAM) format. Known and novel miRNA expression levels, as measured by the number of reads, are displayed in an interface, which shows each RNAseq read relative to the pre-miRNA hairpin. The secondary pre-miRNA structure and read locations for each predicted miRNA are shown and kept in a separate figure file. Moreover, the target genes of known and novel miRNAs are predicted using the TargetScan algorithm, and the targets are ranked according to the confidence score. miRDeep* is an integrated standalone application where sequence alignment, pre-miRNA secondary structure calculation and graphical display are purely Java coded. This application tool can be executed using a normal personal computer with 1.5 GB of memory. Further, we show that miRDeep* outperformed existing miRNA prediction tools using our LNCaP and other small RNAseq datasets. miRDeep* is freely available online at http://www.australianprostatecentre.org/research/software/mirdeep-star.

VLSI-SoC - A low power high performance CMOS voltage-mode quaternary full adder
2006 IFIP International Conference on Very Large Scale Integration, 2006Co-Authors: Ricardo Cunha Goncalves Da Silva, Henri Ivanov Boudinov, Luigi CarroAbstract:Multiple-valued logic, despite of all its theoretical potentialities, has not provided real advantages for arithmetic circuits when compared to the Binary Equivalent ones until now. This paper shows a new efficient method to implement quaternary logic arithmetic circuits using multi-threshold transistors, where 3 power supply lines are used to perform quaternary circuits with low power consumption and high performance. As a demonstration, a quaternary full adder is described in TSMC 0.18?m technology and compared to regular Binary circuits, presenting a 76% reduction in power consumption, and an improvement of 15% regarding speed with a 20% area overhead.

EUSIPCO - ECG comptression using run length encoding
2020Co-Authors: S. Akhter, M. A. HaqueAbstract:A new approach of run length encoding (RLE) is proposed in this research to compress discrete cosine transform (DCT) coefficients of time domain ECG signals. Energy compaction property of DCT facilitates the process of length encoding by accumulating the correlative coefficients into separate segments. Thus the high probability of redundancies in consecutive coefficients facilitates the use of RLE. To increase the CR, two stages of RLE are performed on the quantized DCT coefficients. Then Binary Equivalent of RLE values are obtained by applying Huffman coding. Finally the distortion indices of relevant clinical diagnostic information of the reconstructed signal is measured in terms of weighted diagnostic distortion (WDD), percentage root-mean-squared difference (PRD) and root-mean-square (RMS) error indices. Results indicate that for MIT-BIH Arrhythmia database Record 117, the proposed compression algorithm can achieve a compression ratio of 14.87 with a bit rate of 185 bps.

a theory of electrical conductivity of pseudo Binary Equivalent molten salt
Complex Systems, 2008Co-Authors: Shigeki Matsunaga, Takahiro Koishi, Shigeru TamakiAbstract:Many years ago, Sundheim proposed the “universal golden rule” by experiments, i.e. the ratio of the partial ionic conductivities in molten Binary salt is equal to the inverse mass ratio of each ions, σ+/σ− = m−/m−. In the previous works, we have proved this relation by the theory using Langevin equation, and by molecular dynamics simulations (MD). In this study, the pseudo Binary molten salt NaCl‐KCl system is investigated in the same theoretical framework as previous works as the serial work in molten salts. The MD results are also reported in connection with the theoretical analysis.
