Evolution of the locomotor skeleton in Anolis lizards reflects the interplay between ecological opportunity and phylogenetic inertia

open access: yesNature Communications, 2021
Both ecological opportunity and phenotypic modularity have been suggested to facilitate adaptive radiations. Feiner et al. show that Anolis lizards evolved a new modularity structure in their island adaptive radiation, but that this modularity did not ...

Modularity maximization as a flexible and generic framework for brain network exploratory analysis

open access: yesNeuroImage, 2021
The modular structure of brain networks supports specialized information processing, complex dynamics, and cost-efficient spatial embedding. Inter-individual variation in modular structure has been linked to differences in performance, disease, and ...

Additive Approximation Algorithms for Modularity Maximization [PDF]

open access: yes, 2016
The modularity is a quality function in community detection, which was introduced by Newman and Girvan (2004). Community detection in graphs is now often conducted through modularity maximization: given an undirected graph $G=(V,E)$, we are asked to find

Anatomical network analysis shows decoupling of modular lability and complexity in the evolution of the primate skull.

open access: yesPLoS ONE, 2015
Modularity and complexity go hand in hand in the evolution of the skull of primates. Because analyses of these two parameters often use different approaches, we do not know yet how modularity evolves within, or as a consequence of, an also-evolving ...

Product Networks, Component Modularity and Sourcing

open access: yesJournal of Technology Management & Innovation, 2009
This paper develops product representations as component networks that evolve from sharing of interfaces with other components in a product and links them to the external world of sourcing.

Metabolic robustness and network modularity: a model study. [PDF]

open access: yesPLoS ONE, 2011
Several studies have mentioned network modularity-that a network can easily be decomposed into subgraphs that are densely connected within and weakly connected between each other-as a factor affecting metabolic robustness.

Modular Extensions for Modular (Logic) Languages [PDF]

open access: yes, 2012
We address the problem of developing mechanisms for easily implementing modular extensions to modular (logic) languages. By(language) extensions we refer to different groups of syntactic definitions and translation rules that extend a language. Our use of the concept of modularity in this context is twofold. We would like these extensions to be modular,

Quasispecies Theory for Evolution of Modularity

open access: yes, 2015
Biological systems are modular, and this modularity evolves over time and in different environments. A number of observations have been made of increased modularity in biological systems under increased environmental pressure.

The Principle of Maximal Simplicity for Modular Inorganic Crystal Structures

open access: yesCrystals, 2021
Modularity is an important construction principle of many inorganic crystal structures that has been used for the analysis of structural relations, classification, structure description and structure prediction.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
