© 2009 Joohyun Lee et al. 795 This paper presents the design of an advanced terrestrial digital multimedia broadcasting (AT-DMB) baseband receiver SoC. The AT-DMB baseband is incorporated into a hierarchical modulation scheme consisting of high priority (HP) and low priority (LP) stream decoders. The advantages of the hierarchical modulation scheme are backward compatibility and an enhanced dat...

The production of liver tumors in the rat by the oral administration of N,N-dimethyl-p-aminoazobenzene (DMB) is markedly influenced by diet. Our early work (1,2) showed that the maintenance of normal hepatic riboflavin levels was of importance in protecting rats against tumor formation. The work of Griffin and Baumann (3) and Miller, Miller, Kline, and Rusch (4) has emphasized the relationship ...

Cobalamin (CBL), the biologically active form of vitamin B12, and its analogs, are produced by bacteria only if cobalt supply is adequate. The analogs differ generally by the nucleotide moiety of the molecule. In CBL, 5,6-dimethylbenzimidazole (5,6-DMB) is the base in the nucleotide moiety. The present study aimed to determine if a supplement of 5,6-DMB could increase utilization of dietary cob...

We investigated interactions of bispyridinium para-aldoximes N,N'-(propano)bis(4-hydroxyiminomethyl) pyridinium bromide (TMB-4), N,N'-(ethano)bis(4-hydroxyiminomethyl)pyridinium methanosulphonate (DMB-4), and N,N'-(methano)bis(4-hydroxyiminomethyl)pyridinium chloride (MMB-4) with human erythrocyte acetylcholinesterase phosphorylated by tabun. We analysed aldoxime conformations to determine the ...

With the start of T-DMB service, diverse multimedia broadcasting services became available in the high-speed mobile environment. In addition to high-quality digital radio (audio) and television (video), diverse data services, such as Dynamic Label Segment (DLS), JPEG Slideshow (SLS), Broadcast Web Site (BWS), Traffic and Travel Information (TTI), interactive service using Binary Format for Scen...

Many countries have developed different mobile TV standards such as DVB-H, DMB, MediaFLO, OneSeg, and ATSCM/H. In this paper, we compare different mobile TV standards from the viewpoint of video and audio encoding, data encapsulation, transmission network, and advantages and disadvantages of each technology. Also we propose future mobile TV applications 3-D mobile TV to provide backward compati...

Recently, a Korean standard service, as the designated digital multimedia broadcasting (DMB) system, has been in commercial service following a period of time of careful reflection. Now, the next generation of digital broadcast services will not be limited to digital audio but also extended to a variety of multimedia data services as well as mobile application services. However, the current app...

In Korea, the T-DMB (terrestrial-digital multimedia broadcasting) commercial service was successfully launched. However, T-DMB service providers are very weak for beneficial business because T-DMB A/V services have been started free of charge. Therefore, they want to have pay services like data services. Among these data services, the TTI (Traffic and Travel Information) service based on TPEG (...

Nicotinate mononucleotide (NaMN):5,6-dimethylbenzimidazole (DMB) phosphoribosyltransferase (CobT) from Salmonella enterica plays a central role in the synthesis of alpha-ribazole-5'-phosphate, an intermediate for the lower ligand of cobalamin. In earlier studies it proved difficult to obtain the structure of CobT bound to NaMN because it is hydrolyzed in the crystal lattice in the absence of th...

• Pillar array columns was applied to α-keto acids analysis. α-Keto were derivatized with 1,2-diamino-4,5-methylenedioxybenzene for fluorescence detection. Four separated on pillar in 160 s. Three branched-chain human plasma samples successfully quantified. Branched-chain (BCKAs, namely, α-ketoisovaleric acid (KIV), α-ketoisocaproic (KIC), and α-keto-β-methylvaleric (KMV)) are related many dise...
