Compounds 1 and 2 were isolated from the genus Coleus for the first time.Compounds 3 and 4 were isolated from C.forskohlii for the first time.

化合物1和2为首次从鞘蕊花属植物中分离得到，并首次运用2D-NMR技术对其碳氢信号进行准确归属，化合物3和4为首次从毛喉鞘蕊花中分离得到。

Truncation mutations in the adenomatous polyposis coli protein are responsible for familial and sporadic colonic tumours. Except for its function as a role in regulating b-catenin, recent studies show that APC has additional roles in cytoskeletal regulation. It binds to microactin and microtubules directly and indirectly. Furthermore, APC plays an important role in mediating the detraction of chromosome.

编码APC蛋白(adenomatous polyposis coli， APC)基因的缺失突变会导致家族性和散发性的结肠癌，APC蛋白除了能直接参与Wnt信号途径调节b-catenin的浓度之外，最近的研究表明APC蛋白能够与细胞骨架的主要成分微管和微丝直接或间接结合，通过调节微管的解聚和聚合，间接调节染色体的分离，作为潜在的细胞骨架调节分子将细胞骨架与重要的细胞信号转导通路紧密联系在一起。

It is demonstrated that the source number can be estimated by computing the rank of the data matrix of the mixed signals.

通过理论分析，提出并证明了在信号源盲分离问题中，可以通过计算混合信号数据矩阵的秩数来确定信号源的个数。

The signal can be decomposed into different frequency components with the help of Muti-scale Analysis, and Wavelet methods offers an effective way for signal filtering, signal-noise separating, and character...

通过小波变换可对信号的不同频率成分进行分解，为信号的滤波、信噪分离和弱信号特征提取提供了有效的途径。

In this chapter, we review the evolution of Particle Filtering from sequential importance sampling, resampling, to Regularized Particle Filter.

本章主要以混沌信号为代表，讨论了单通道非线性信号的处理问题，根据混合信号数量的不同，分成混沌去噪和混沌分离两类问题讨论。

It can separate sync signals from NTSC, PAL and SECAM video signals, and produces composite sync output signal, back porch output signal, horizontal sync signal, vertical sync signal and odd/ even field output signal.

它可以对NTSC、AL、ECAM 制式的视频信号进行同步分离，获得所需的同步信号，还能准确地输出复合同步、沿输出、同步、同步和奇/场输出信号。

Firstly the sampling convolutive mixture signals are reseted for matching instantaneous mixture model, then considering non-stationarity of the sources, space whitening and joint block-diagonalization method is exploited to obtain the original signals.

该算法先将采集到的卷积混合信号进行重排，使之满足重新定义向量后的瞬时混合模型特征，然后考虑到信号的非平稳特性，采用空间白化和联合近似块对角化方法分离出源信号。

Although nuclear cascades in ethylene signal transduction pathway from EIN3 to ERF1 to PR proteins has been established in Arabidopsis thaliana, a similar route from EIN3 to EREBPs to fruit ripening and senescence has not been elucidated in Lycopersicon esculentum .

乙烯对植物的生长发育起重要的调控作用，随着乙烯信号转导研究的不断深入，许多乙烯信号转导组分已被分离和鉴定，并在模式植物拟南芥中已建立乙烯信号传递过程中的核内级联反应：EIN3→ERF1→病原相关蛋白，但在番茄中还没有建立EIN3→EREBPs→果实成熟相关基因的相似路径。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
