1Post-transcriptional regulation of vascular endothelial growth factor: Implications for tumor angiogenesis显示文摘脉管的内皮生长因素(VEGF ) 是一个有势力为批评的分泌 mitogen 生理并且肿瘤血管生成。VEGF 的规定发生在几个层次,包括抄写, mRNA 稳定,翻译,和各种各样的 isoforms 的微分细胞的本地化。在我们 VEGF 的 post-transcriptional 规定的理解的最近的进展在 VEGF mRNA 的 5'UTR 包括内部 ribosomal 入口地点的稳定的 mRNA 绑定蛋白质,投,和发现的鉴定。Monoclonal anti-VEGF 抗体最近在人为使用被同意,但是为高全身的剂量受不了需要。RNA 干扰(RNAi ) 技术正在被使用在试管内并且在有有希望的结果的动物模型。这里,我们在 VEGF 的 post-transcriptional 规定上考察文学并且在为治疗学的利益指向这些机制描述最近的进步。Peter S Yoo Abby L Mulkeen Charles H Cha 2006World Journal of Gastroenterology2006,12,31:11
2柔性直流输电并网风电厂的低电压穿越能力改进(英文)显示文摘To achieve active control of the AC voltage magnitude of wind power plant(WPP)collector network and improve the fault ride-through(FRT)capability,an FRT scheme based on feed forward DC voltage control is presented for voltage source converter-high voltage direct current(VSC-HVDC)connected offshore WPPs.During steady state operation,an open loop AC voltage control is implemented at the WPP-side VSC of the HVDC system so that any possible control interactions between WPP-side VSC and VSC of wind turbine are minimized.Whereas during any grid fault,a dynamic AC voltage reference is made according to both the DC voltage error and AC active current from the WPP collector system,thus ensuring fast and robust FRT of the VSC-HVDC-connected offshore WPPs.Under the unbalanced fault condition in the host power system,the resulting oscillatory DC voltage is directly used in the VSC AC voltage controller at the WPP side so that the WPP collector system voltage also reflects the unbalance in the main grid.Time domain simulations are performed to verify the efficacy of the FRT scheme based on the proposed feed forward DC voltage control.Simulation results show satisfactory FRT responses of the VSC-HVDC-connected offshore WPP under balanced and unbalanced faults in the host power system,as is shown under a serious fault in the WPP collector network.Ranjan SHARMA Qiuwei WU Seung Tae CHA Kim Hφj JENSEN Tony Wederberg RASMUSSEN Jacob ΦSTERGAARD 2015电力系统自动化2015,39,3:4
3用于测风激光雷达的三通道法布里-珀罗标准具性能分析显示文摘研制了用于瑞利散射多普勒激光雷达的三通道法布里-珀罗(Fabry-Pérot)标准具,采用He-Ne激光对其进行检测,利用产生的干涉图案检测了两个边缘通道的厚度差为74.70±2.24 nm,对应频谱间隔为5.05±0.07 GHz;锁定通道与其中一个边缘通道的厚度差为27.16±1.90 nm,对应频谱间隔为1.79±0.07 GHz。数值模拟结果表明:采用脉冲能量350 mJ波长355 nm、重复频率30 Hz的激光器和口径450 mm的望远镜,利用该标准具作为鉴频器,在0-40 km高度,瑞利散射多普勒激光雷达的径向风速测量误差小于2.53 m/s,测量精度比理论设计值2.94 m/s提高了约14.1%。舒志峰 唐磊 董吉辉 沈法华 孙东松 窦贤康 CHA H K 2010光学学报2010,30,5:4
