Treatment-related topological reorganization of the structural connectome in major depressive disorder with suicidal ideation [PDF]

BMC Psychiatry
Background Major depressive disorder with suicidal ideation (MDD-SI) is associated with a high risk of mortality. The specific longitudinal alterations in brain structural networks associated with SI remain unclear. We aimed to identify treatment-related

Alterations in resting-state neural networks in subacute non-fluent aphasia after stroke: a fNIRS study [PDF]

BMC Neurology
Background Post-stroke aphasia is a prevalent and often disabling language impairment. Despite its high incidence, the neuropathological mechanisms underlying post-stroke aphasia and the neural substrates of functional recovery remain poorly understood ...

Algorithmic Graph Theory, Reinforcement Learning and Game Theory in MD Simulations: From 3D Structures to Topological 2D-Molecular Graphs (2D-MolGraphs) and Vice Versa

Molecules, 2023
This paper reviews graph-theory-based methods that were recently developed in our group for post-processing molecular dynamics trajectories. We show that the use of algorithmic graph theory not only provides a direct and fast methodology to identify ...

Towards glueball masses of large-N SU(N) pure-gauge theories without topological freezing

Physics Letters B, 2022
In commonly used Monte Carlo algorithms for lattice gauge theories the integrated autocorrelation time of the topological charge is known to be exponentially-growing as the continuum limit is approached.

Generalized Permutants and Graph GENEOs

Machine Learning and Knowledge Extraction, 2023
This paper is part of a line of research devoted to developing a compositional and geometric theory of Group Equivariant Non-Expansive Operators (GENEOs) for Geometric Deep Learning. It has two objectives. The first objective is to generalize the notions

Merging of degree and index theory

Fixed Point Theory and Applications, 2006
The topological approaches to find solutions of a coincidence equation f1(x)=f2(x) can roughly be divided into degree and index theories. We describe how these methods can be combined.

Minimum spanning tree analysis for epilepsy magnetoencephalography (MEG) data

Exploration of Neuroprotective Therapy, 2023
Aim: Recently, brain network research is actively conducted through the application of graph theory. However, comparison between brain networks is subject to bias issues due to topological characteristics and heterogeneity across subjects.

Countably Generated Algebras of Analytic Functions on Banach Spaces

Axioms, 2023
In the paper, we study various countably generated algebras of entire analytic functions on complex Banach spaces and their homomorphisms. Countably generated algebras often appear as algebras of symmetric analytic functions on Banach spaces with respect
