Plasma biomarker‐informed brain topology for cognitive resilience: applications in non‐pharmacological interventions concerning cognitive aging [PDF]

open access: yesAlzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring
INTRODUCTION In the context of non‐pharmacological interventions (NPIs), cognitive resilience refers to the capacity to enhance cognition from NPIs in the presence of neurodegeneration, and it is closely linked to brain network topological ...

A Method to Validate Operational Capability Index Model of Heterogeneous Combat Networks Based on Characteristic Topology Analysis

open access: yesIEEE Access, 2020
In high-tech informative warfare, the combat system-of-systems which become increasingly functional and complex can be abstracted as heterogeneous combat networks (HCNs).

Noncommutative topology and the world’s simplest index theorem [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2010
In this article we outline an approach to index theory on the basis of methods of noncommutative topology. We start with an explicit index theorem for second-order differential operators on 3-manifolds that are Fredholm but not elliptic. This low-brow index formula is expressed in terms of winding numbers. We then proceed to show how it is derived as a

Link Prediction Method Based on Topological Tightness of Resource Transmission Nodes [PDF]

open access: yesJisuanji gongcheng, 2021
To address the problem that the existing local similarity RA index based on network topology does not consider the topological closeness of transmission nodes,this paper proposes a node topology closeness index and link prediction method.The important ...

Remarks on Wiener Index of Bipolar Fuzzy Incidence Graphs

open access: yesFrontiers in Physics, 2021
Fuzzy data plays an important role in daily life, and fuzzy structured data is usually represented by fuzzy graphs, where the graph structure is used to describe the associated structure of the fuzzy data.

Topological indices of bipolar fuzzy incidence graph

open access: yesOpen Chemistry, 2021
The topological index of graph has a wide range of applications in theoretical chemistry, network design, data transmission, etc. In fuzzy graph settings, these topological indices have completely different definitions and connotations.

The twisted index and topological saddles

open access: yesJournal of High Energy Physics, 2022
Abstract The twisted index of 3d $$ \mathcal{N} $$ N = 2 gauge theories on S1× Σ has an algebro-geometric interpretation as the Witten index of an effective supersymmetric quantum mechanics. In this paper, we consider the contributions to the supersymmetric quantum mechanics from topological ...

Topological Inference of the Conley Index

open access: yesJournal of Dynamics and Differential Equations, 2023
Abstract The Conley index of an isolated invariant set is a fundamental object in the study of dynamical systems. Here we consider smooth functions on closed submanifolds of Euclidean space and describe a framework for inferring the Conley index of any compact, connected isolated critical set of such a function with high confidence from a ...

Reliability based geometrically nonlinear bi-directional evolutionary structural optimization of elasto-plastic material

open access: yesScientific Reports, 2022
The aim of this paper is to integrate the reliability-based analysis into topology optimization problems. Consequently, reliability-based topology optimization (RBTO) of geometrically nonlinear elasto-plastic models is presented.
