| 1 | 5G大规模多入多出(MIMO)测试台:从理论到实现显示文摘1引言大规模的多输入多输出(MIMO)是5G无线通信研究中一个令人兴奋的领域。对下一代无线数据通信网络,它将带来显著的进步,拥有在更高的数据速率下以更高的可靠性容纳更多用户同时消耗更低功耗的能力。使用NI大规模MIMO的应用程序框架. | Erik Luther | 2014 | 国外电子测量技术2014，33，11： | 6 |

| 3 | 乙酰辅酶A羧化酶1通过调控CyclinD1/CDK4影响肾透明细胞癌细胞增殖显示文摘乙酰辅酶A羧化酶1(acetyl-CoA carboxylase1,ACC1)是脂肪酸合成途径的限速酶。ACC1与多种代谢性疾病和癌症密切相关。然而,ACC1在肾透明细胞癌(clear cell renal cell carcinoma,ccRCC)中的作用及机制却未见报道。本研究以肾透明细胞癌786-O和Caki-1细胞为对象,探讨ACC1异常表达对肾透明细胞癌增殖的影响及其作用机制。首先通过红油-O-染色发现,相比HK2(human kidney-2)细胞,786-O和Caki-1细胞中的脂肪含量明显增加。检索TCGA数据库分析发现,ACC1的蛋白质水平在肾透明细胞癌组织中的表达显著高于正常肾组织(P<0.001)。由分期分级分析发现,临床TNM各期的ACC1蛋白表达均显著高于正常组织。且ACC1表达水平越高,病理分级越高。而ACC1的mRNA水平高表达与肾透明细胞癌病人的不良预后呈正相关。Western印迹结果显示,与对照组HK2细胞相比,在786-O和Caki-1细胞中,ACC1的表达明显增加。通过慢病毒载体构建ACC1敲低的稳转细胞株,由红油-O-染色结果显示,ACC1敲低可显著降低786-O和Caki-1细胞的脂肪含量。CCK-8和平板克隆结果显示,ACC1低表达可显著降低786-O和Caki-1细胞的增殖和克隆形成能力。流式细胞周期结果显示,ACC1敲低可使细胞周期G0/G1期阻滞,并且抑制细胞周期蛋白D1(cyclinD1)和CDK4表达。以上结果表明,ACC1在肾透明细胞癌中异常高表达,并通过上调细胞周期蛋白D1和CDK4表达调控细胞周期进程,促进肿瘤增殖,提示不良预后,ACC1有望成为ccRCC干预治疗的潜在新靶点。 | 程婧 倪月莉 AGBANA Yannick Luther 云芳 杨晖 赵雷 李小渝 张雪丹 张巧 杨哲 况应敏 朱月春 | 2021 | 中国生物化学与分子生物学报2021，37，6： | 5 |
| 4 | 国际阴茎疾病专题讨论会显示文摘1996年1月26~27日。在德国汉堡召开了国际阴茎疾病专题讨论会。 Juenermann(德国曼海姆)在“阴茎解剖和勃起的生理基础”概论中,强调阴茎海绵体平滑肌弛缓对勃起的决定性意义,它一方面是自主的,另一方面依赖于上皮不是神经所引起。在此,神经化学递质氧化氮(NO、平滑肌弛缓的起动物质)和肠血管肽(VIP、维持平滑肌弛缓)有特殊作用。反射性勃起由副交感神经、交感神经和体神经三种神经系统支配。 | Luther A. 李金华 | 1997 | 国外医学(泌尿系统分册)1997，17，2： | 3 |
| 5 | Conditional inversion to estimate parameters from eddy-flux observations显示文摘Aims Data assimilation is a useful tool to extract information from large datasets of the net ecosystem exchange(NEE)of CO_(2) obtained by eddy-flux measurements.However,the number of parameters in ecosystem models that can be constrained by eddy-flux data is limited by conventional inverse analysis that estimates parameter values based on one-time inversion.This study aimed to improve data assimilation to increase the number of constrained parameters.Methods In this study,we developed conditional Bayesian inversion to maximize the number of parameters to be constrained by NEE data in several steps.In each step,we conducted a Bayesian inversion to constrain parameters.The maximum likelihood estimates of the constrained parameters were then used as prior to fix parameter values in the next step of inversion.The conditional inversion was repeated until there were no more parameters that could be further constrained.We applied the conditional inversion to hourly NEE data from Harvard Forest with a physiologically based ecosystem model.Important Findings Results showed that the conventional inversion method constrained 6 of 16 parameters in the model while the conditional inversion method constrained 13 parameters after six steps.The cost function that indicates mismatch between the modeled and observed data decreased with each step of conditional Bayesian inversion.The Bayesian information criterion also decreased,suggesting reduced information loss with each step of conditional Bayesian inversion.A wavelet analysis reflected that model performance under conditional Bayesian inversion was better than that under conventional inversion at multiple time scales,except for seasonal and half-yearly scales.In addition,our analysis also demonstrated that parameter convergence in a subsequent step of the conditional inversion depended on correlations with the parameters constrained in a previous step.Overall,the conditional Bayesian inversion substantially increased the number of parameters to be constrained by NEE data and can be a powerful tool to be used in data assimilation in ecology. | Xiaowen Wu Yiqi Luo Ensheng Weng Luther White Yong Ma Xuhui Zhou | 2009 | Journal of Plant Ecology2009，2，2： | 3 |
