查询词典 complex function

The characteristics of genetic algorithm,global searching of Genetic Algorithm for complex,multi-apices,and nondifferentiable nonlinear function are applied to the Hopfield neural network,which results in the inputting pattern getting away from the attraction domain of fault pattern and the Hopfield neural network associative memory remaining high success rate while the noise to signal ratio is high.

0引言Hopfield神经网络模型在神经计算、优化求极值、联想记忆等方而取得了重大应用，联想记忆能够从不完整的或模糊的信息中联想出存储在记忆中的某个完整清晰的图像模式，但一般离散Hopfield模型存在很多伪稳定点[2]，这些伪稳定点的存在，不仅使真稳定点的吸引域变小，而且使网络

Chronicity maybe result from many factors with complex mechanism.HCV may evade the host immune surveillance due to the hypermutation of HCV gene; HCV has the nature of pantropic,the tissues outside liver can provide virus for repeatedly infection of liver; The HCV receptors,such as CD81,LDL receptor,scavenger receptor B type I,L-SIGN,DC-SIGN and so on,may influence organism humoral immunity and the cellular immunity function in different degrees; HCV infection also may cause the reduction of quantity of organism immune cell or functional defect,low response of humoral immune response,tolerance of cellular immunity,then,the host finally transforms into chronic infection condition.

其慢性化的机制非常复杂，是由多个因素造成的，HCV因其基因高变性可以逃避宿主的免疫监视；HCV具有泛嗜性，肝外组织又可为肝组织的反复感染提供病毒来源；CD81、LDL受体、清道夫受体B类Ⅰ型及L-SIGN、DC-SIGN等HCV受体又可不同程度地影响机体的体液免疫和细胞免疫功能；HCV感染亦可直接导致机体免疫细胞数量减少或功能缺陷，体液免疫应答水平低下、细胞免疫耐受，宿主最终转变为慢性感染状态。

The study of transcriptive regulatory networks intends to infer regulations between genes from microarray data, and reveals the complex life of cell. Also far from being completed, the ability to recreate transcriptive regulatory networks from available experimental data facilitates the systematic dissection of cell function. The research of transcriplive regulatory networks is an important topic in functional genomics, and one of the most challenging questions in the front of bioinformatics and system biology. Several typical mathematical models and their new research developments are discussed concisely.
