Optimization of degree distribution of the joint network LDPC code for orthogonal multiple-access relay channel (MARC) is investigated in this paper. We first calculated the code capacity of the source-destination link of orthogonal MARC based on a Gaussian approximation, where two sources communicate with one destination in the presence of one relay. Then,… (More)
The letter presents a fourth-harmonic mixer based on planar schottky diode working at 330-500GHz. The result of simulation predicts that conversion loses well below 14dB from 369GHz to 477GHz with 6 dBm of local oscillator power. Therefore, the good performance of mixers in wide bandwidth and low conversion loss provides designers with a better choice.
In this paper, a 420GHz Sub-Harmonic Mixer based on planar schottky diode is presented. The mixer circuit was fabricated on the 50um thick quartz substrate with a pair of anti-parallel flip-chipped schottky diodes. The planar schottky diode is fabricated in China Electronics Technology Group Corporation-13(CETC-13). Simulated results for the 420 GHz mixer… (More)
Knowledge of the fine root dynamics of different life forms in forest ecosystems is critical to understanding how the overall belowground carbon cycling is affected by climate change. However, our current knowledge regarding how endogenous or exogenous factors regulate the root dynamics of understory vegetation is limited. The aims of this study were to… (More)
TCM still plays an important role in the treatment of male infertility. TCM therapy is based on the diagnosis of TCM syndrome. But the essence of TCM syndrome is not well studied by modern science, especially in male infertility. We aim to investigate the metabolic changes of infertility males with Kidney-Yang deficiency syndrome (KYDS), the major TCM… (More)
Nrf2 expression. These results suggest that IDS-T2DM induces testicular cell death presumably through caspase-8 activation and mitochondria-mediated cell death pathways, and also by significantly down-regulating testicular Nrf2 expression and function. SFN up-regulates testicular Nrf2 expression, and its target antioxidant expression, which was associated… (More)
