Actin Cytoskeleton Role in the Maintenance of Neuronal Morphology and Long-Term Memory

Cells, 2021
Evidence indicates that long-term memory formation creates long-lasting changes in neuronal morphology within a specific neuronal network that forms the memory trace.

Generative network models for simulating urban networks, the case of inter-city transport network in Southeast Asia

Cybergeo, 2016
This paper examines the driving forces of urban network formation through the simulation of inter-city transport networks in Southeast Asia. We present a generative network model (GNM) considering geographical and topological effects, thus combining ...

Activity driven modeling of time varying networks [PDF]

, 2012
Network modeling plays a critical role in identifying statistical regularities and structural principles common to many systems. The large majority of recent modeling approaches are connectivity driven.

On the Tension Between Stability and Efficiency in Two-Way Flow Network with Small Decay [PDF]

Annals of Dunarea de Jos University. Fascicle I : Economics and Applied Informatics
The tension between stability and efficiency in network formation models refers to a common finding in the literature of social networks: equilibrium networks and efficient networks often exhibit substantially different characteristics.

Regional geographies of intercity corporate networks: The use of exponential random graph models to assess regional network‐formation

Papers in Regional Science, 2013
Drawing on the ‘local buzz and global pipeline’ perspective on the geographies of production in knowledge‐intensive industries, our analysis associates observed network patterns with exogenous city characteristics (e.g., GDP and population) and ...

Determinants of Equilibrium Selection in Network Formation: An Experiment

Games, 2018
Theoretical models on network formation focus mostly on the stability and efficiency of equilibria, but they cannot deliver an understanding of why specific equilibrium networks are selected or whether they are all actually reachable from any starting ...

Planar growth generates scale free networks [PDF]

, 2016
In this paper we introduce a model of spatial network growth in which nodes are placed at randomly selected locations on a unit square in $\mathbb{R}^2$, forming new connections to old nodes subject to the constraint that edges do not cross.

Network Features and Processes as Determinants of Organizational Interaction during Extreme Events

Complexity, Governance & Networks, 2015
Despite the widely acknowledged importance of collaboration among participants in governance networks, a limited number of studies have attempted to statistically model the processes by which those networks form.

econet: An R Package for Parameter-Dependent Network Centrality Measures

Journal of Statistical Software, 2022
The R package econet provides methods for estimating parameter-dependent network centrality measures with linear-in-means models. Both nonlinear least squares and maximum likelihood estimators are implemented.
