Anticipation of ventricular tachyarrhythmias by a novel mathematical method: Further insights towards an early warning system in implantable cardioverter defibrillators.

PLoS ONE, 2020
Implantable cardioverter defibrillators (ICD) are the most effective therapy to terminate malignant ventricular arrhythmias (VA) and therefore to prevent sudden cardiac death. Until today, there is no way to predict the onset of such VA.

Fuzzy Number-Valued Fuzzy Graph [PDF]

Control and Optimization in Applied Mathematics, 2016
Graph theory has an important role in the area of applications of networks and clustering. In the case of dealing with uncertain data, we must utilize ambiguous data such as fuzzy value, fuzzy interval value or values of fuzzy number.

Spectral analysis of the matrix Sturm–Liouville operator

Boundary Value Problems, 2019
The self-adjoint matrix Sturm–Liouville operator on a finite interval with a boundary condition in general form is studied. We obtain asymptotic formulas for the eigenvalues and the weight matrices of the considered operator.

Solving the Minimum Spanning Tree Problem Under Interval-Valued Fermatean Neutrosophic Domain [PDF]

Neutrosophic Sets and Systems
In classical graph theory, the minimal spanning tree (MST) is a subgraph that lacks cycles and efficiently connects every vertex by utilizing edges with the minimum weights.

Time estimation and beta segregation: An EEG study and graph theoretical approach. [PDF]

PLoS ONE, 2018
Elucidation of the neural correlates of time perception constitutes an important research topic in cognitive neuroscience. The focus to date has been on durations in the millisecond to seconds range, but here we used electroencephalography (EEG) to ...

Functional network of contextual and temporal memory has increased amygdala centrality and connectivity with the retrosplenial cortex, thalamus, and hippocampus

Scientific Reports, 2023
In fear conditioning with time intervals between the conditioned (CS) and unconditioned (US) stimuli, a neural representation of the CS must be maintained over time to be associated with the later US.

Constraint Network and Structural Evolution B: Spectral Theory of Connectivity Phase Transitions in Random Interval Graphs—From Circle Covering to High-Dimensional Emergence

Starting from the probabilistic ontology of random constraint networks, this paper rigorously constructs the product probability space for random interval graphs,transforming the random arc covering problem on the circle into a connectivityphase transition problem for interval graphs.
