Error-Correcting Codes Scheme for Remote Control System
Wang, Mu kun,Yin, Xiao Hua,Zhao, Xian Ming,Li, Zheng Lian 대한전자공학회 1992 HICEC:Harbin International Conference on Electroni Vol.1 No.1
How to rise the reliability of the data transmission is one of the main problem faced by modern digital communication designer. This paper studies the error-correcting codes being suitable for the channel existing both the random error and the burst error. A new error control scheme is given. The scheme is a concatenated coding system using an interleaved Reed-Solomon code with symbols over GF (2⁴) as the outer code and a Vitcrbi-decoded convolutional code as the inner code. As a result of the computer simulation, it is proved that the concatenated coding system has a output at a very low bit error rate (BER) and can correct a lot of compound error pattern. It is suitable for the serious disturb channel existing both the random error and the burst error. This scheme will be adopted for a remote control system

Acanthopanax trifoliatus (L) Merr (AT) is commonly used as an herbal medicine and edible plant in some areas of China and other Asian countries. AT is thought to have anticancer effects, but potential mechanisms remain unknown. To assess the anticancer properties of AT, we exposed prostate cancer cells to AT extracts and assessed cell proliferation and signaling pathways. An ethanol extract of AT was suspended in water followed by sequential extraction with petroleum ether, ethyl acetate and n-butanol. PC-3 cells were treated with different concentrations of each extract and cell viability was determined by the MTT and trypan blue exclusion assays. The ethyl acetate extract of the ethanol extract had a stronger inhibitory effect on growth and a stronger stimulatory effect on apoptosis than any of the other extracts. Mechanistic studies demonstrated that the ethyl acetate extract suppressed the transcriptional activity of NF-${\kappa}B$, increased the level of caspase-3, and decreased the levels of phospho-Erk1/2 and phospho-Akt. This is the first report on the anticancer activity of AT in cultured human prostate cancer cells. The results suggest that AT can provide a plant-based medicine for the treatment or prevention of prostate cancer.

In this study, three swarm intelligence (SI)-based maximum power point tracking (MPPT) techniques for photovoltaic generation systems (PGSs) operating under partially shaded conditions (PSCs) are investigated. The compared methods include particle swarm optimization (PSO), firefly algorithm (FA) and cuckoo search (CS). Simulated results for 252 different shading patterns will be provided and some conclusion will be made. This study presents reference information for scholars planning to carry out research in this field.

Heishui county, located in northwest Sichuan province, southwestern China, is an endemic area of zoonotic visceral leishmaniasis (VL) and is the most intractable area. VL is never destroyed in it. Asymptomatic dogs (Leishmania parasites have been diagnosed but clinically healthy) are considered to be a potential reservoir host in zoonotic VL area, and most can lead to infection of individuals, that is a new challenge for controlling VL in humans. The present study aimed to assess the Leishmania infection rate of asymptomatic dogs in Heishui county. Total 105 asymptomatic domestic dogs were gathered from 4 districts in Heishui county to investigate the infection rate with serological and molecular methods based on ELISA and kinetoplast minicircle DNA(kDNA) PCR, respectively. Out of 105 dogs, 44 (41.9%) were positive by more than 1 method; 21 (20.0%) were positive by ELISA, and 30 (28.6%) were positive by kDNA-PCR. Our study showed that Leishmania infection of domestic dogs which is clinically healthy is prevalent in the studied district, and the asymptomatic dogs infected by Leishmania may be the primary reason for the prevalence of visceral leishmaniasis in the area.

<P>A novel halophilic, filamentous actinomycete strain, designated YIM 93221<SUP>T</SUP>, was isolated from a salt lake in Xinjiang province, north-west China, and subjected to a polyphasic taxonomic characterization. The isolate grew with 9-23 % (w/v) NaCl and did not grow without NaCl. The isolate formed spiny aerial mycelium and did not form spores at maturity. The isolate contained <I>meso</I>-diaminopimelic acid as the diagnostic diamino acid and glucose, glucosamine, mannose and an unknown sugar as the major whole-cell sugars. The phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides and an unknown phospholipid. MK-8(H4) was the predominant menaquinone. The major fatty acid was iso-C16 : 0. The DNA G+C content was 68.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain YIM 93221<SUP>T</SUP> formed a distinct lineage within the suborder <I>Pseudonocardineae</I> and showed 91.9-94.8 % 16S rRNA gene sequence similarity with members of the suborder <I>Pseudonocardineae</I>. On the basis of the evidence from this polyphasic study, a novel genus and species, <I>Haloechinothrix alba</I> gen. nov., sp. nov., are proposed. The type strain of <I>Haloechinothrix alba</I> is YIM 93221<SUP>T</SUP> (=DSM 45207<SUP>T</SUP> =CCTCC AB 208140<SUP>T</SUP>).</P>

<P>A Gram-positive actinobacterium, designated strain YIM 90716(T), was isolated from a saline soil sample collected from Ganjiahu Suosuo Forest National Nature Reserve in Xinjiang Province, north-west China. The new isolate contained lysine, glutamic acid and alanine with peptidoglycan type Lys-Ala(3) (variation A3alpha). The major phospholipids were phosphatidylglycerol and diphosphatidylglycerol. The predominant menaqinone was MK-7(H(2)). The major fatty acids were anteiso-C(15 : 0), iso-C(16 : 0) and anteiso-C(17 : 0). The DNA G+C content of strain YIM 90716(T) was 68.0 mol%. Chemotaxonomic properties supported the affiliation of strain YIM 90716(T) to the genus Kocuria. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the organism was related most closely to Kocuria kristinae DSM 20032(T) (96.8 % similarity) and showed lower levels of 16S rRNA gene similarity (<96.5 %) with the type strains of other species of the genus Kocuria. The results of fatty acid analysis and physiological and biochemical tests allowed the genotypic and phenotypic differentiation of strain YIM 90716(T) from its closest relatives. On the basis of data from the present polyphasic study, strain YIM 90716(T) is considered to represent a novel species of the genus Kocuria, for which the name Kocuria halotolerans sp. nov. is proposed. The type strain is YIM 90716(T) (=DSM 18442(T)=KCTC 19172(T)=CCTCC AB 206069(T)).</P>

<P>A Gram-staining-positive, facultatively anaerobic, non-motile and moderately halophilic actinobacterium, designated YIM 93306<SUP>T</SUP>, was isolated from a salt lake in Xinjiang province, north-west China, and subjected to a polyphasic taxonomic study. Strain YIM 93306<SUP>T</SUP> grew in the presence of 2-16 % (w/v) NaCl and did not grow without NaCl. The peptidoglycan type was A4<I>α</I> with an l-Lys-l-Glu interpeptide bridge. The whole-cell sugars were glucosamine, arabinose, mannose and two unknown sugars. The predominant menaquinone was MK-8(H4). The major fatty acids were iso-C15 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, one unknown phosphoglycolipid and one unknown phospholipid. The DNA G+C content was 68.3 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain YIM 93306<SUP>T</SUP> fell within the radius of the suborder <I>Micrococcineae</I>. Its closest phylogenetic neighbour was the type strain of <I>Ruania albidiflava</I> (AS 4.3142<SUP>T</SUP>; 96.2 % 16S rRNA gene sequence similarity), the sole recognized species of the genus <I>Ruania</I>. Sequence similarities between strain YIM 93306<SUP>T</SUP> and members of other genera of the suborder <I>Micrococcineae</I> were <95.2 %. On the basis of phylogenetic analysis, phenotypic characteristics and chemotaxonomic differences, a novel genus and species, <I>Haloactinobacterium album</I> gen. nov., sp. nov., is proposed. The type strain of the species is YIM 93306<SUP>T</SUP> (=DSM 21368<SUP>T</SUP> =KCTC 19413<SUP>T</SUP> =CCTCC AB 208069<SUP>T</SUP>). Based on phylogenetic characteristics and 16S rRNA gene signature nucleotide patterns, the genera <I>Ruania</I> and <I>Haloactinobacterium</I> gen. nov. are proposed to belong to a novel family, <I>Ruaniaceae</I> fam. nov.</P>
