Hierarchical Modularity and Intermodule Optimization

Separate compilation is an important tool for coping with design complexity in large software projects. When done right it can also be used to create software libraries, thus promoting code reuse. But separate compilation comes in various flavors and has many facets: namespace management, linking, optimization, dependencies. Many programming languages identify modular units with units of compil...

Functional Annotation of Hierarchical Modularity

In biological networks of molecular interactions in a cell, network motifs that are biologically relevant are also functionally coherent, or form functional modules. These functionally coherent modules combine in a hierarchical manner into larger, less cohesive subsystems, thus revealing one of the essential design principles of system-level cellular organization and function-hierarchical modul...

Hierarchical Modularity in Human Brain Functional Networks

The idea that complex systems have a hierarchical modular organization originated in the early 1960s and has recently attracted fresh support from quantitative studies of large scale, real-life networks. Here we investigate the hierarchical modular (or "modules-within-modules") decomposition of human brain functional networks, measured using functional magnetic resonance imaging in 18 healthy v...

Hierarchical Organization of Modularity in Metabolic Networks

Hierarchical organization of modularity in metabolic networks.

Spatially or chemically isolated functional modules composed of several cellular components and carrying discrete functions are considered fundamental building blocks of cellular organization, but their presence in highly integrated biochemical networks lacks quantitative support. Here, we show that the metabolic networks of 43 distinct organisms are organized into many small, highly connected ...
