A Fractal Operator on Some Standard Spaces of Functions

, 2020
Through appropriate choices of elements in the underlying iterated function system, the methodology of fractal interpolation enables us to associate a family of continuous self-referential functions with a prescribed real-valued continuous function on a ...

DFC-LSTM: A Novel LSTM Architecture Integrating Dynamic Fractal Gating and Chaotic Activation for Value-at-Risk Forecasting

Mathematics
Accurate Value-at-Risk (VaR) forecasting is challenged by the non-stationary, fractal, and chaotic dynamics of financial markets. Standard deep learning models like LSTMs often rely on static internal mechanisms that fail to adapt to shifting market ...

The Ahlqvist Subphenotypes of Type 2 Diabetes: A Narrative Review of Scientific Evidence and Its Potential Contribution to Precision Diabetes

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Background Among several approaches, k‐means clustering has established as a widely used method to classify people with type 2 diabetes (T2D) into distinct subphenotypes, and the Ahlqvist T2D subphenotypes of Severe Insulin Deficient Diabetes (SIDD), Mild Age‐Related Diabetes (MARD), Mild Obesity Diabetes (MOD) and Severe Insulin Resistant ...

Does Digitalization Widen Labor Income Inequality?

International Economic Review, EarlyView.
ABSTRACT We develop a growth model that endogenizes the occupational choice of workers with different ability levels to study how digitalization affects labor income inequality. The framework incorporates digitalization's multifaceted effects on the economy: (i) it influences economic growth through automation, and (ii) it affects labor income ...

The Effect of Prostration (Sajdah) on the Prefrontal Brain Activity: A Pilot Study

Basic and Clinical Neuroscience, 2019
Introduction: “Sajdah”, a prostration position, is part of Muslim daily prayers. It seems to have several effects on the brain and heart function. This study aimed to investigate the prefrontal brain activity after 10 seconds of Sajdah in the direction ...

Beyond the Moderating Role of Neuroticism on Evaluative Conditioning: Threat Appraisal

Journal of Personality, EarlyView.
ABSTRACT Objective Reality perception is often altered by general dispositional factors that are associated with emotional vulnerability and emerge in a specific learning context. The current study examined whether neuroticism and looming cognitive style, factors that account for emotional vulnerability, interact to influence emotional learning ...

Lacunarity of Fractal Superlattices: a Remote Estimation using Wavelets [PDF]

, 2005
The lacunarity provides a useful parameter for describing the distribution of gap sizes in discrete self-similar (fractal) superlattices and is used in addition to the similarity dimension to describe fractals.

Simulación numérica de reacciones químicas catalizadas.

Momento, 2007
The kinetics of the 2CO + O2 -> 2CO2 reaction on Pt(100) nanoparticles was studied using the Monte Carlo simulation method. These particles present surfaces with (1×2) and (1×1) structures, which correspond to α and β phases, respectively.

On the Application of Mann-Iterative Scheme with h-Convexity in the Generation of Fractals

Fractal and Fractional
Self-similarity is a common feature among mathematical fractals and various objects of our natural environment. Therefore, escape criteria are used to determine the dynamics of fractal patterns through various iterative techniques. Taking motivation from

Fractal Analysis of Periodontal Tissues in Geriatric Patients With Different Periodontal Conditions: A Retrospective Study

Oral Diseases, EarlyView.
ABSTRACT Objective This study evaluated the relationship between fractal dimension (FD) values and periodontal status in geriatric patients using digital panoramic radiographs. Methodology In this retrospective observational study, 147 elderly individuals were classified as periodontally healthy (n = 30), gingivitis (n = 32), Stage I periodontitis (n =
