Connectivity functions and polymatroids
Advances in Applied Mathematics, 2016 A {\em connectivity function on} a set $E$ is a function $ :2^E\rightarrow \mathbb R$ such that $ (\emptyset)=0$, that $ (X)= (E-X)$ for all $X\subseteq E$ and that $ (X\cap Y)+ (X\cup Y)\leq (X)+ (Y)$ for all $X,Y \subseteq E$. Graphs, matroids and, more generally, polymatroids have associated connectivity functions.

Evaluation of Whole-Brain Resting-State Functional Connectivity in Spinal Cord Injury - A Large-Scale Network Analysis Using Network Based Statistic [PDF]
, 2017 Large-scale network analysis characterizes the brain as a complex network of nodes and edges to evaluate functional connectivity patterns. The utility of graph-based techniques has been demonstrated in an increasing number of restingstate functional MRI (

The Role of Corpus Callosum Development in Functional Connectivity and Cognitive Processing [PDF]
, 2012 The corpus callosum is hypothesized to play a fundamental role in integrating information and mediating complex behaviors. Here, we demonstrate that lack of normal callosal development can lead to deficits in functional connectivity that are related to ...

A Framework to Control Functional Connectivity in the Human Brain
, 2019 In this paper, we propose a framework to control brain-wide functional connectivity by selectively acting on the brain's structure and parameters. Functional connectivity, which measures the degree of correlation between neural activities in different ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...
