Fractal Homeomorphism for Bi-affine Iterated Function Systems

, 2016
The paper concerns fractal homeomorphism between the attractors of two bi-affine iterated function systems. After a general discussion of bi-affine functions, conditions are provided under which a bi-affine iterated function system is con-tractive, thus ...

Fractional Calculus of Fractal Interpolation Function on [0,b](b>0)

Abstract and Applied Analysis, 2014
The paper researches the continuity of fractal interpolation function’s fractional order integral on [0,+∞) and judges whether fractional order integral of fractal interpolation function is still a fractal interpolation function on [0,b](b>0) or not ...

Cognitive and Neuroimaging Divergence Between Juvenile and Adult FUS Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive motor neuron degeneration. Fused in sarcoma (FUS)‐associated juvenile ALS (jALS) represents a distinct and aggressive subgroup with rapid deterioration and poor prognosis.

Attractors of directed graph IFSs that are not standard IFS attractors and their Hausdorff measure [PDF]

, 2012
"GCB was supported by an EPSRC Doctoral Training Grant whilst undertaking this work"For directed graph iterated function systems (IFSs) defined on R, we prove that a class of 2-vertex directed graph IFSs have attractors that cannot be the attractors of ...

Fractals in $$S_b$$ S b -metric spaces

Complex & Intelligent Systems
This study aims to discover attractors for fractals by using generalized F-contractive iterated function system, which falls within a distinct category of mappings defined on $$S_b$$ S b -metric spaces.

Best proximity point results of iterated function systems for α-ψ-contractions

In this paper, we present two new concepts, called α-ψ-iterated function system and α-ψ-proximal iterated function system, by using α-ψ-contractions and α-ψ-proximal contractions.

Common Attractor for Hutchinson θ-Contractive Operators in Partial Metric Spaces

Mathematical and Computational Applications
This paper investigates the existence of common attractors for generalized θ-Hutchinson operators within the framework of partial metric spaces. Utilizing a finite iterated function system composed of θ-contractive mappings, we establish theoretical ...

Natural Frequencies of Levodopa‐Induced Dyskinesia in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Abnormal involuntary movements, known as dyskinesias, are common complications of levodopa treatment in patients with Parkinson's disease and can significantly impair quality of life. The underlying pathophysiology remains unclear, and current therapeutic options are limited.
