This introductory article serves as areader's guide to the 13 articles in the Section of theEncyclopedia which is titled "Complex Networks and Graph Theory". These articles will be discussed in the context of three broad themes:network structure; dynamics of network structure; and dynamical ...
尽管对 Seq 对象调用 str() 方法将以字符串的形式返回全长序列,但是你经常不需要特地做这个转换。 当使用 print 打印声明是,Python 会自动转换。 >>> print my_seq GATCGATGGGCCTATATAGGATCGAAAATCGC 当你进行 Python 字符串格式化或者插入操作符(% )时,可以直接把 Seq 对象和 %s 占位符一起使用: ...
当有多个模体时,我们就会想去比较它们。 在我们开始比较之前,应当要指出模体的边界通常比较模糊。这也就是说我们需要比较不同长度的模 体,因此这些比较也要涉及到相关的比对。所以我们需要考虑两个东西: • 模体比对 • 比较比对后模体的相关函数 为了比对模体,我们使用 PSSMs 的不含间隔的比对,并且用 0 来代...
These developments in the theory of complex networks have inspired new applications in the field of neuroscience. Graph analysis has been used in the study of models of neural networks, anatomical connectivity, and functional connectivity based upon fMRI, EEG and MEG. These studies suggest that the...
Recent developments in the quantitative analysis of complex networks, based largely on graph theory, have been rapidly translated to studies of brain network organization. The brain's structural and functional systems have features of complex networks — such as small-world topology, highly connected ...
Algebraic graph theory 3. Eigenvalues of the adjacency matrix 4. Eigenvalues of the Laplacian Q 5. Spectra of special types of graphs 6. Density function of the eigenvalues 7. Spectra of complex networks On the other hand, the chapters of Part II, entitled "Eigensystem and polynomials," are...
主流是基于 Spectral Graph Theory 的(当然还有上面的答主提到的vertex domain,就不展开啦)。下面会展开讲。 这种方法很大的限制是,只能应用在fixed graph上。因为graph 中一个小小的改变,就可以改变 Fourier mode 中的representation,而对齐 Fourier mode又是一个很难的问题 (graph matching problem)。所以学到的 spe...

Graph spectra and the detectability of community structure in networks We study networks that display community structure -- groups of nodes within which connections are unusually dense. Using methods from random matrix theory... RR Nadakuditi,MEJ Newman - 《Physical Review Letters》 被引量: 306...
However, it remains unclear whether the altered degree of coupling is also related to a change of global configuration of functional networks. A suitable approach to study topological features of complex networks involves the use of graph theory. Graph theoretical analysis provides a framework for ...
