Modular Curves, Modular Surfaces and Modular Fourfolds [PDF]

open access: yes, 2007
This article surveys some recent work of the author on Hilbert modular fourfolds X. After some preliminaries on the cohomology and special, codimension 2 cycles Z on X of Hirzebruch-Zagier type, a proof of the Tate conjecture for X over abelian fields is exposed. It is followed by a description of a method to construct classes in the Bloch's Chow group

2-Modular Matrices

open access: yesSIAM Journal on Discrete Mathematics, 2022
A rank-$r$ integer matrix $A$ is $Δ$-modular if the determinant of each $r \times r$ submatrix has absolute value at most $Δ$. The class of $1$-modular, or unimodular, matrices is of fundamental significance in both integer programming theory and matroid theory.

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 ...

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,

A Cre‐dependent lentiviral vector for neuron subtype‐specific expression of large proteins

open access: yesFEBS Letters, EarlyView.
We designed a versatile and modular lentivector comprising a Cre‐dependent switch and self‐cleaving 2A peptide and tested it for co‐expression of GFP and a 2.8 kb gene of interest (GOI) in mouse cortical parvalbumin (PV+) interneurons and midbrain dopamine (TH+) neurons.

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.
