User-Curated Image Collections: Modeling and RecommendationSep 18 2015Most state-of-the-art image retrieval and recommendation systems predominantly focus on individual images. In contrast, socially curated image collections, condensing distinctive yet coherent images into one set, are largely overlooked by the research ... More
Rare decays of B-> J/ψD^(*) and B->η_c D^(*)in pQCD ApproachDec 28 2005Motivated by the recent measurement of the upper limit of ${B}^0 \to J/\psi D$ branching ratio, which is important in accounting for the soft $J/\psi$ production in B decays, we investigate ${B}^0 \to J/\psi D^{(\star)}$ and $\eta_c D^{(\star)}$ decays ...

Orbital Angular Momentum-based Space Division Multiplexing for High-capacity Underwater Optical CommunicationsApr 23 2016To increase system capacity of underwater optical communications, we employ the spatial domain to simultaneously transmit multiple orthogonal spatial beams, each carrying an independent data channel. In this paper, we multiplex and transmit four green ... More
