V-BLAST (Vertical Bell Labs Layered Space-Time) 시스템은 다중 안테나를 사용하는 시스템에서 각각의 레이어를 간섭 무효화 및 제거기법을 통하여 추정하기 때문에 간단한 복잡도에 비해 높은 전송률을 가능하게 한다. 본 논문에서는 신호 공간 다이버시티 기법을 적용시킨 V-BLAST 시스템을 제안하고자 한다. 신호 공간 다이버시티 기법의 큰 장점은 신호좌표를 회전시키고 인페이즈 (inphase) 와 쿼드러쳐 (quadrature) 성분을 섞어줌으로서 추가적인 대역폭이나 전송 파워의 상승 없이도 다이버시티 이득을 얻을 수 있다....

Porcine reproductive and respiratory syndrome virus (PRRSV) has a high degree of genetic variation. In this study, we characterized the genetic variation and evolutionary relationships among circulating PRRSV strains in southern China. We analyzed 29 NSP2 strains and 150 ORF5 strains from clinical samples collected in southern China during 2007?2014. The alignment results showed that the nucleotide identity similarities of the two genes among these strains were 80.5%?99.7% and 80.9%?100%,...

Bacillus (B.) anthracis, the etiological agent of anthrax, is one of the most genetically monomorphic bacteria species in the world. Due to the very limited genetic diversity of this species, classification of isolates of this bacterium requires methods with high discriminatory power. Single nucleotide repeat (SNR) analysis is a type of variable-number tandem repeat assay that evaluates regions with very high mutation rates. To subtype a collection of 21 isolates that were obtained during a...

in the isolates was 81.6∼100% for type 1 viruses and 81.4∼100% for type 2 viruses. Phylogenetic analysis of the ORF 5 sequences showed that types 1 and 2 PRRSVs from Korea were mainly classified into three and four clusters, respectively. The analyzed isolates were distributed throughout the clusters independent of the isolation year or geographical origin. In conclusion, our results indicated that the genetic diversity of PRRSVs from Korean pig farms is high and has been increasing over time.

(AMPAR) were not generally saturated. Here, we found that the small miniature excitatory postsynaptic currents (mEPSCs) showed significantly slower rise times than the large mEPSCs when the sucrose-induced mEPSCs recorded in cyclothiazide (CTZ), a blocker for AMPAR desensitization, were sorted by size. The slow rise time of the small mEPSCs might result from slow release through a non-expanding fusion pore, consistent with postfusional control of neurotransmitter release at central synapses.

However, these assays usually involve sampling potential host plants, but identifying infected plants when they are asymptomatic is challenging, and many plants, especially wild ones, contain inhibitors to DNA amplification. We used an alternative approach which utilized aphid vectors and indicator plants to...

논문에서는MIMO(Multi-Input Multi-Out)-OFDM(Orthogonal Frequency Division Multiplexing) 시스템에 다중 안테나를 가진 relay를 적용 할 경우, cooperation 통신을 하기 위한 기법을 제안하고 성능을 분석한다. 이동국과 relay간 뿐만 아니라 relay와 기지국간에도 STC(space time coding)에 의해 MIMO채널이 형성되어 cooperative diversity와 MIMO에 의한 diversity 이득을 함께 얻을 수 있어 시스템의 성능이 크게 향상된다. 또한 이동국과 relay에서 송신전력을 위한 간략화 된 전력할당 기법을 제안하여 이에 따른 시스템의 성능이 향상됨을...

of matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS; applied using a MALDI Biotyper) to conduct rapid, easy and accurate identification of E. ictaluri. MALDI-TOF MS could directly detect the specific peptide patterns of cultured E. ictaluri colonies with high (＞ 2.0, indicating species-level identification) scores. MALDI Biotyper 3.0 software revealed that all of the strains examined in this study possessed highly similar peptide peak patterns. In...

is a key step for disease prevention, however, the pathogen diversity, population structure, and virulence are largely unknown. In this study, we studied 50 Xcc strains including 39 Xcc isolates collected from cabbage in 20 regions across China, us- ing multilocus sequence genotyping (MLST), repetitive DNA sequence-based PCR (rep-PCR), and pathogenicity tests. For MLST analysis, a total of 12 allelic profiles (AP) were generated, among which the largest AP was AP1 containing 32 strains. Further...

to study the genetic diversity and detect molecular and biochemical markers associated with Fusarium wilt resistance in the tested genotypes. The results showed that certain genotypes of faba bean were resistant to Fusarium wilt, while most of the genotypes were highly susceptible. The percentage of disease severity ranged from 32.83% in Assiut-215 to 64.17% in Misr-3. The genotypes Assiut-215, Roomy-3, Marut-2, and Giza-2 were the most resistant, and the genotypes Misr-3, Misr-1, Assiut-143,...

of Apulia region (Lecce province, southern Italy). Studies were carried out for detection and diversity evaluation of the Apulian strain of Xylella fastidiosa. The presence of the pathogen in olive samples was detected by PCR amplifying the 16S rDNA, gyrase B subunit (gyrB) and HL hypothetical protein genes and single nucleotide polymorphisms (SNPs) assessment was performed to genotype X. fastidiosa. Twelve SNPs were recorded over gyrB and six SNPs were found for HL gene. Less variations were...

Cotton leaf curl is devastating disease of cotton characterized by leaf curling, vein darkening and enations. The disease symptoms are induced by DNA satellite known as Cotton leaf curl Multan betasatellite (CLCuMuB), dominant betasatellite in cotton but another betasatellite known as Chili leaf curl betasatellite (ChLCB) is also found associated with the disease. Grafting experiment was performed to determine if host plant resistance is determinant of dominant population of betasatellite in...

In recent years, incidence and severity of these diseases have been increased in Iran. Fifty seven F. proliferatum single-spore isolates collected from diseased maize, rice, onion and sugarcane plants at different areas were used to study genetic diversity by determination of vegetative compatibility groups (VCGs). Chlorate-resistant nitrate non-utilizing (nit) mutants were recovered from selected isolates of F. proliferatum and used in complementation tests. All isolates in which both nit1 and...

표준의 순방향 fundamental 채널에 대하여 시뮬레이션을 통해 확인하였다. 그리고, 그 결과를 기존의 IS-2000 표준에서 채택된 OTD와 STS (space-time spreading)의 성능과 비교하였다. 본 논문에서 제안한 방법을 IS-2000 시스템에 적용할 경우, 1% FER (frame error rate)을 얻기 위한 송신전력이 OTD의 경우보다 0.5-7.7dB 정도 감소되어 STS의 성능과 거의 일치하였다. 뿐만 아니라, 송신신호의 PAR(peak-to-average power ratio)가 STS보다 적으므로, 기지국 전력증폭기와 같은 RF 회로의 복잡도를 감소시킬 수 있는 장점이 있다.
