Topological dynamics for the endograph metric II: extremely radical properties

open access: yesJournal of Inequalities and Applications
Given a dynamical system ( X , f ) $(X,f)$ we investigate several topological dynamical properties for its Zadeh extension ( F ( X ) , f ˆ ) $(\mathcal{F}(X),\hat{f})$ endowed with the endograph metric d E $d_{E}$ .

GENERALIZED ASYMPTOTIC NOTATIONS VIA FILTERS: A NEW FRAMEWORK FOR ALGORITHM ANALYSIS

open access: yesUral Mathematical Journal
This paper introduces a  generalization of asymptotic notation using filters, a topological structure. We present key properties of this generalization, including reflexivity, symmetry, and transitivity, supported by illustrative examples.

Disorder-induced topological transitions in a multilayer topological insulator

open access: yesPhysical Review B
We examine the impact of non-magnetic disorder on the electronic states of a multilayer structure comprising layers of both topological and conventional band insulators. Employing the Burkov-Balents model with renormalized tunneling parameters, we generate phase diagrams correlating with disorder, demonstrating that non-magnetic disorder can induce ...

Topological Lifshitz transitions [PDF]

open access: yesLow Temperature Physics, 2017
Different types of Lifshitz transitions are governed by topology in momentum space. They involve the topological transitions with the change of topology of Fermi surfaces, Weyl and Dirac points, nodal lines, and also the transitions between the fully gapped states.

Graph analysis based on SCN reveals novel neuroanatomical targets related to tinnitus distress

open access: yesFrontiers in Neuroscience
PurposeTinnitus is considered a neurological disorder affecting both auditory and nonauditory networks. This study aimed to investigate the structural brain covariance network in tinnitus patients and analyze its altered topological properties ...

Notions of mixing and sensitivities for triangular map and its non-autonomous components

open access: yesApplied General Topology
In this paper, we relate the dynamics of the triangular map to the dynamics of its individual components. We prove that if the non-autonomous system generated by a transitive point (for the base map) is topological mixing then the triangular map is ...

EEG-Based Brain Functional Network Analysis for Differential Identification of Dementia-Related Disorders and Their Onset

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering
Diagnosing and treating dementia, including mild cognitive impairment (MCI), is challenging due to diverse disease types and overlapping symptoms. Early MCI detection is vital as it can precede dementia, yet distinguishing it from later stage dementia is

Existence of edge modes in periodic microstrip transmission line

open access: yesScientific Reports
The microstrip of modulated width is a realization of a one-dimensional photonic crystal operating in the microwave regime. Like any photonic crystal, the periodic microstrip is characterised by the presence of frequency bands and band gaps that enable ...

A Unified Framework for Temporal Similarity: Coupling Time-Scale Effects and Composite Temporal Objects in Geoscientific Retrieval

open access: yesIEEE Access
Temporal similarity is critical for retrieving and integrating geoscientific data. Existing approaches often neglect the effect of time scale and lack efficient models for handling composite temporal objects composed of multiple points and intervals.
