In this article, we consider the uniform circular arrays (UCAs) with the number of antenna elements insufficient to apply the traditional beamspace-based algorithms, which are labeled as sparse UCAs. For such UCAs, we propose a new hybrid approach for 2D direction-of-arrival (DOA) estimation in the presence of mutual coupling. Using the manifold(More)
ZD958 was the most low-N-efficient line among five maize and two teosinte lines. Zea parviglumis and Zea diploperennis were insensitive to N limitation. Maize and teosinte genetically and evolutionarily diverged in gene regulation. GDH2, ASN2, and T4 were consistently down-regulated across seven lines. Maternal asymmetric inheritance and heterosis vigor(More)
Utilization of heterosis is one of the most outstanding advancements in plant breeding. However, its genetic basis is not well understood. We used digital gene expression technology to investigate the transcriptomes of the mature maize embryo of an elite maize hybrid Zhengdan958 and its parental lines to screen differentially-expressed genes and to study(More)
The signal integrity of the circuit, as one of the important design issues in high-speed digital system, is usually seriously affected by the signal reflection due to impedance mismatch in the DDR3 bus. In this paper, a novel optimization method is proposed to optimize impedance mismatch and reduce the signal reflection. Specifically, by applying the via(More)
PCI Express (PCIe) interface has been extensively used in high-speed digital systems for multimedia communication. With the migration of the video processing algorithms from host to embedded hardware, multi-channel video capturing systems will produce not only different channels of raw video data but also different types of auxiliary data, such as analyzed(More)
