This paper presents key design techniques and challenges in implementing one of the first integrated, energy-efficient 60GHz transceivers including baseband circuitry. The 90nm CMOS direct-conversion design (Fig. 18.5.1) operates from a 1.2V supply and has been optimized for 5-to-10Gb/s QPSK modulation centered at 60GHz. To achieve power consumption of(More)
A microbial consortium, designated WCS-6, was established by successive subcultivation in the presence of rice straw under static conditions. The degradation efficiencies of WSC-6 for 0.5 g filter paper, cotton and rice straw after 3 days of cultivation were 99.0±0.7%, 76.9±1.5% and 81.3±0.8%, respectively as determined by gravimetrical methods. Nine(More)
Distant hybridization can result genome duplication and allopolyploid formation which may play a significant role in the origin and evolution of many plant species. It is unclear how the two or more divergent genomes coordinate in one nucleus with a single parental cytoplasm within allopolyploids. We used cytological and molecular methods to investigate the(More)
Nitric oxide (NO) is a key signal molecule that is involved in plant response to various abiotic stresses. The present study was conducted to investigate the effects of NO on Typha angustifolia which has been subjected to cadmium stress. Our results showed that sodium nitroprusside (SNP, a NO donor) treatment could significantly mitigate both the Cd(More)
A mesophilic lignocellulolytic microbial consortium BYND-5, established by successive subcultivation, was applied to enhance the biogas production. The degradation efficiency of BYND-5 for rice straw was more than 49.0 ± 1.8% after 7 days of cultivation at 30°C. Various organic compounds, including acetic acid, propionic acid, butyric acid and glycerin were(More)
This paper presents a highly linear dual-band mixed-mode polar power amplifier fully integrated in a standard 65nm bulk CMOS process. An ultra-compact single-transformer passive network provides dual-band optimum load-pull impedance matching, parallel power combining, and double even-harmonic rejection without any tunable element or band selection switch.(More)
Interkinetic nuclear migration (INM) is a key feature of cortical neurogenesis. INM functions to maximize the output of the neuroepithelium, and more importantly, balance the self-renewal and differentiation of the progenitors. Although INM has been reported to be highly correlated with the cell cycle, little is known about the effects of cell cycle(More)
orf18 (ac18) of Autographa californica multiple nucleopolyhedrovirus (AcMNPV) is a highly conserved gene in lepidopteran nucleopolyhedroviruses, but its function remains unknown. In this study, an ac18 knockout AcMNPV bacmid was generated to determine the role of ac18 in baculovirus life cycle. After transfection of Sf-9 cells, the ac18-null mutant showed(More)
A lignin degradation bacterial consortium named LDC was screened from the sludge of a reeds pond by a restricted subculture. It could break down 60.9% lignin in reeds at 30°C under conditions of static culture within 15 days. In order to analyze the diversity of LDC, plate isolation, 16S rDNA clone library and ARDRA (Amplified Ribosomal DNA Restriction(More)
MicroRNAs (miRNAs) are a class of non-coding, small RNAs recognized as important regulators of gene expression. Although plant miRNAs have been extensively studied in model systems, less is known in other plants with limited genome sequence data, including Paeonia ostii. In this work, we used high-throughput sequencing to identify conserved and nonconserved(More)
