Graph Theory in the Analysis of Arithmophobia

International Journal of Innovative Technology and Exploring Engineering, 2019
In this paper, Graph theoretical concepts are applied to analyze the reasons behind Arithmophobia commonly found among the students.Bull graph is used to epitomize Mild Arithmophobia which occurs when the preparation of students to face any test is deficient.Flower graph is used to represent Intense Arithmophobia.

Data-Driven Sequence of Changes to Anatomical Brain Connectivity in Sporadic Alzheimer’s Disease

Frontiers in Neurology, 2017
Model-based investigations of transneuronal spreading mechanisms in neurodegenerative diseases relate the pattern of pathology severity to the brain’s connectivity matrix, which reveals information about how pathology propagates through the connectivity ...

Graph theory analysis of the dopamine D2 receptor network in Parkinson’s disease patients with cognitive decline

Journal of Neuroscience Research, 2020
Cognitive decline in Parkinson's disease (PD) is a common sequela of the disorder that has a large impact on patient well‐being. Its physiological etiology, however, remains elusive.

Graph theory and qualitative analysis of reaction networks

Networks & 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 ...

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

Frontiers 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.

Identification of innovative technology enablers and drone technology determinants adoption: a graph theory matrix analysis framework

Operations Management Research, 2023
Two main things ensure technology is integrated into a system: enablers, which help technology get in; and determinants, which act as filters to ensure that the right technology gets in. The study develops a decision framework for ranking determinants of

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

Frontiers 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.
