Modeling and simulation of the formation of vascular networks [PDF]

ESAIM: Proceedings, 2002
Summary: The formation of blood vessels is driven by chemical and mechanical interactions between the cells and their extracellular matrix. New vasculature can emerge in the presence of angiogenic factors or as a result of cell traction forces onto the extracellular matrix.

Machine Learning-Based probabilistic prediction of glacial lake formation using erosional and topographic features

Scientific Reports
Glacial lake formation in high mountain regions, particularly the Himalayas, is accelerating due to climate-driven glacier retreat, increasing the risk of glacial lake outburst floods (GLOFs) that threaten downstream populations and infrastructure. While

Detecting Overlapping Communities Based on Influence-Spreading Matrix and Local Maxima of a Quality Function

Computation
Community detection is a widely studied topic in network structure analysis. We propose a community detection method based on the search for the local maxima of an objective function.

A Survey of Models of Network Formation: Stability and Efficiency [PDF]

, 2005
I survey the recent literature on the formation of networks. I provide definitions of network games, a number of examples of models from the literature, and discuss some of what is known about the (in)compatibility of overall societal welfare with ...

A Cosmic String Specific Signature on the Cosmic Microwave Background

, 1993
Using an analytical model for the string network we show that the kurtosis of cosmic microwave background (CMB) temperature gradient maps is a good statistic to distinguish between the cosmic string model and inflationary models of structure formation ...

Random Network Modeling of Tight Formations

, 2016
The objective if this study is investigating the capability of random network modeling techniques to predict fluid flow behaviour in unconventional formations. 3D random networks are constructed in order to represent Berea sandstone, synthetic oil-sand, and the Mesaverde formation located in north Wyoming, United States.

Can extremism guarantee pluralism? [PDF]

, 2008
Many models have been proposed to explain opinion formation in groups of individuals; most of these models study opinion propagation as the interaction between nodes/agents in a social network. Opinion formation is a complex process and a realistic model

Analysis of the Driving Mechanism of China’s Provincial Carbon Emission Spatial Correlation Network: Based on the Dual Perspectives of Dynamic Evolution and Static Formation

Systems
Against the backdrop of China’s commitment to achieving carbon peaking by 2030 and carbon neutrality by 2060, inter-provincial carbon emissions form a complex interconnected spatial network—clarifying its operational mechanisms is crucial for optimizing ...

Stable Networks and Convex Payoffs [PDF]

Recently a variety of link-based stability concepts have emerged in the literature on game theoretic models of social network formation. We investigate two basic formation properties that establish equivalence between some well known types of stable ...
