Empirical performance of rough volatility models in the KOSPI 200 options market using deep surrogates

This study provides a systematic comparison of the pricing performance of the rough volatility models—rBergomi and rHeston—with that of classical one-factor stochastic volatility (SV) and stochastic volatility jump-diffusion (SVJ) models in the KOSPI 200 index options market. Using an extensive daily option...

Promoting urban-rural modernization from the perspective of the digital economy

In an era defined by the digital divide, the digital economy has emerged as a pivotal force driving urban-rural modernization. This study analyzes China’s digital economy from 2011 to 2023, evaluating its influence on equitable regional development across 30 provinces, municipalities, and autonomous regions. We develop...

Controllable AI modeling of northern and southern timbercraft convergence in Qing interior canopies

This study examines interior canopies from the Qianlong–Jiaqing era (1736–1820) of the Qing dynasty to model northern–southern timbercraft convergence through controllable AI generation. We constructed northern official and southern garden semantic lexicons, trained dual LoRA modules on Stable Diffusion v1.5, and gener...

Controlling the Latent Diffusion Model for Generative Image Shadow Removal via Residual Generation

Large-scale generative models have achieved remarkable advancements in various visual tasks, yet their application to shadow removal in images remains challenging. These models often generate diverse, realistic details without adequate focus on fidelity, failing to meet the crucial requirements of shadow removal, which...

Computational Data and MATLAB Codes for Fuzzy Parametric Uncertainty Propagation in a Fractional Reaction–Diffusion Hahnfeldt Tumor–Vascular Model

This repository contains the MATLAB codes and numerical data supporting the computational results of the study “Fuzzy Parametric Uncertainty Propagation in a Fractional Reaction–Diffusion Hahnfeldt Tumor–Vascular Model.” The computational framework combines Caputo fractional temporal dynamics, spatial diffusion, and tr...

Fully mixed finite element methods for the coupling of viscoelasticity and reaction-diffusion models

FBR Inverted Lock Mechanism

Abstract / Description This appendix to the Free Body Rotation Model (FBR) examines the kinematic and thermodynamic implications of sign-reversing the radial phase velocity (\bm{v_r \to -v_r}) within a topologically protected 2:1 phase lock. By inverting the radial gradient, the model converts an internal confining str...

Financial Technology and Financial Inclusion: Evidence from East African Community Member Countries

This study examined the effect of financial technology on financial inclusion in the eight East African Community member countries. Financial technology was operationalised through penetration rate, usage rate and transaction volume. Anchored on the Diffusion of Innovations Theory, the study adopted a positivist philos...

THE AI LITERACY DIVIDE: ACCESS, CAPABILITY, AND INEQUALITY IN THE AGE OF GENERATIVE AI

The rapid diffusion of artificial intelligence (AI), particularly generative AI (GenAI), has shifted the digital-inequality question from whether people can access digital technologies toward whether they can understand, evaluate, and use AI effectively. Yet these dimensions remain fragmented across datasets and measur...
