The development of reagents with high affinity and specificity to small molecules is crucial for the high-throughput detection of chemical compounds, such as toxicants or pollutants. Aptamers are short and single-stranded (ss) oligonucleotides able to recognize target molecules with high affinity. Here, we report the selection of ssDNA aptamers that bind to(More)
This paper presents a clock and data recovery (CDR) circuit that supports dual data rates of 5.4Gbps and 3.24Gbps for DisplayPort v1.2 sink device. The quarter-rate linear PD in the proposed CDR reduces jitter by enhancing the up and down pulse width. A charge pump (CP) is designed to compensate the different up and down pulse width of the PD and to reduce(More)
This paper describes a clock and data recovery (CDR) circuit that supports dual data rates of 2.7Gbps and 1.62Gbps for DisplayPort standard. The proposed CDR has a dual mode voltage-controlled oscillator (VCO) that changes the operating frequency with a “Mode” switch control. The chip has been implemented using 0.18μm CMOS process. Measured results show the(More)
Human constitution, the fundamental basis of oriental medicine, is categorized into different patterns for a particular disease according to the physical, physiological, and clinical characteristics of the individuals. Obesity, a condition of metabolic disorder, is classified according to six patterns in oriental medicine, as follows: spleen deficiency(More)
Obesity is known to be influenced by a number of genes, including the β3 subunit of G protein (GNB3), β3-adrenergic receptor (ADRB3), uncoupling protein 2 (UCP2), and peroxisome proliferator activated receptor gamma (PPARγ). The single nucleotide polymorphisms (SNPs) of the above genes, such as GNB3-C825T, ADRB3-Trp64Arg, UCP2-3'UTR 45 bp del/ins, and(More)
