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)
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)
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.
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)
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)
mechanisms of spermatogenesis. Nodal could promote proliferation of mouse spermatogonial stem/progenitor cells via Smad2/3 and oct-4 activation. The objective of this study was to determine the role of Nodal signaling in the differentiation of iPS cells to male germ cells. Design: Comparative and controlled study. Materials and methods: In this study,… (More)
