Graph theory and qualitative analysis of reaction networks

open access: yesNetworks & Heterogeneous Media, 2008
Different types of macroscopic reaction kinetics can be derived from microscopic molecular interactions, with the law of mass action being the most widely used one in standard situations. After such a modeling step, where primarily the types of reactions are identified, it becomes a problem to analyse qualitative properties of complete regulatory ...

Expanding Horizons: Graph Theory’s Multifaceted Applications [PDF]

open access: yesE3S Web of Conferences
A subfield of mathematics called graph theory studies networks of points interconnected by lines. Researchers may model and examine the structure of a network using graph theory.

Graph theory and the analysis of fracture networks [PDF]

open access: yesJournal of Structural Geology, 2019
Abstract Two-dimensional exposures of fracture networks can be represented as large planar graphs that comprise a series of branches (B) representing the fracture traces and nodes (N) representing their terminations and linkages. The nodes and branches may link to form connected components (K), which may contain fracture-bounded regions (R) or blocks.

Structural Brain Network Abnormalities in Parkinson’s Disease With Freezing of Gait

open access: yesFrontiers in Aging Neuroscience, 2022
ObjectiveDiffusion tensor imaging (DTI) studies have investigated white matter (WM) integrity abnormalities in Parkinson’s disease (PD). However, little is known about the topological changes in the brain network.

Alterations of Brain Structural Network in Parkinson’s Disease With and Without Rapid Eye Movement Sleep Behavior Disorder

open access: yesFrontiers in Neurology, 2018
Background and objectiveRapid eye movement sleep behavior disorder (RBD) has a strong association with alpha synucleinpathies such as Parkinson’s disease (PD) and PD patients with RBD tend to have a poorer prognosis.

Graph geometry from effective resistances [PDF]

open access: yes, 2023
The main subject of this thesis is the effective resistance — a measure of distance between the nodes of a graph which reflects how close or well- connected two nodes are, taking into account all paths between them and their interconnections.

EEG-Based Semantic Vigilance Level Classification Using Directed Connectivity Patterns and Graph Theory Analysis

open access: yesIEEE Access, 2020
This paper proposes two novel methods to classify semantic vigilance levels by utilizing EEG directed connectivity patterns with their corresponding graphical network measures.
