—In this paper, a concurrent transmission scheduling algorithm is proposed to enhance the resource utilization efficiency for multi-Gbps millimeter-wave (mmWave) networks. Specifically, we exploit spatial-time division multiple access (STDMA) to improve the system throughput by allowing both non-interfering and interfering links to transmit concurrently,(More)
—Millimeter-wave (mmWave) communications is a promising enabling technology for high rate (Giga-bit) multime-dia applications. However, because of the high propagation loss at 60 GHz band, mmWave signal power degrades significantly over distance. Therefore, a traffic flow being transmitted over multiple short hops can attain higher throughput than that over(More)
BACKGROUND Bacteriophage Phi12 is a member of the Cystoviridae and is distinct from Phi6, the first member of that family. We have recently isolated a number of related phages and five showed high similarity to Phi12 in the amino acid sequences of several proteins. Bacteriophage Phi2954 is a member of this group. RESULTS Phi2954 was isolated from radish(More)
Bacteriophage 6 is a double-stranded RNA (dsRNA) virus whose genome is packaged sequentially as three single-stranded RNA (ssRNA) segments into an icosahedral procapsid which serves as a compartment for genome replication and transcription. The procapsid shell consists of 60 copies each of P1(A) and P1(B), two nonequivalent conformers of the P1 protein.(More)
We aim to explore the impacts of high dose methylprednisolone therapy (HDMT) and rituximab on circulating B cells in NMO patients. Twenty-two NMO patients in the acute relapse phase were treated with HDMT and 9 patients in the remission stage were treated with rituximab. The frequencies of circulating CD19(+)CD27(+) memory B cell (Bmem),(More)
—Millimeter-wave (mmWave) communications is a promising enabling technology for high rate (Giga-bit) multi-media applications. However, because oxygen absorption peaks at 60 GHz, mmWave signal power degrades significantly over distance. Therefore, a traffic flow transmitting over multiple short hops is preferred to improve flow throughput. In this paper, we(More)

Abstract—In this paper, we study concurrent beamforming issue for achieving high capacity in indoor millimeter wave networks. The general concurrent beamforming issue is first formulated as an(More)
The repeated transmission to pigs and humans, and the long-term endemicity in terrestrial poultry of H9N2 viruses in China lend urgency to the study of their ecology and pathogenicity. In the present paper, we reported an H9N2 virus sublineage isolated from chickens in northern China from 2007 to 2009 has high lethality for mice. Phylogenetic analysis of(More)
