Understanding the Role of Financial Development and Research Productivity in Shaping Economic Complexity in Africa

Abstract This study has two main objectives, first, to investigate the unconditional effects of research productivity on economic complexity, and second, to examine the synergistic relationship between financial development and research productivity in bolstering Africa’s economic complexity. The estimation framework i...

EvoJump: A Comprehensive Framework for Evolutionary Ontogenetic Analysis

EvoJump models ontogenetic development as a jump-diffusion process sweeping across a fixed analytical plane (the laser plane), yielding dynamic cross-sectional views of phenotypic distributions across a developmental timeline. It bundles data ingestion and QC (DataCore), stochastic process modeling across seven process...

Public information sharing during public health emergencies: an adaptive-network evolutionary game

Introduction Public health emergencies can generate verified sharing, opportunistic dissemination, and strategic silence within the same communication environment, yet diffusion-centered approaches offer limited explanation of how these contrasting behaviors emerge together or change as communication relationships evol...

VR-enhanced Visual System for Stereoscopic Presentation Display of Oil Paintings

Abstract The clarity and fidelity of stereoscopic presentation play a crucial role in the display of oil painting images. However, most existing stereoscopic image presentation methods suffer from poor image quality and low fidelity. To address this issue, this paper raises an image optimization method based on Dark Ch...

Research on the Architecture of Artificial Intelligence-Driven Personalized Customization Industrial Design System

Experiments show that the proposed human–machine collaborative system for mobile and immersive scenes can significantly improve the design efficiency and user experience, reduce the decision-making delay, provide a reference for small and medium-size customization platforms, and provide empirical support for artificial...

THE IMPACT OF FINTECH COMPANIES ON FINANCIAL INCLUSION IN NIGERIA.

Financial inclusion has become a major policy objective in developing economies due to its potential to reduce poverty, promote economic growth, and improve social welfare. In Nigeria, a significant proportion of the population has historically remained outside the formal financial system due to factors such as inadequ...

Pointwise Monotonicity of the Allen--Cahn Flow and Dynamical Limitations of Energy-Stable Schemes

Abstract Energy stability is fundamental in the numerical approximation of phase-field models, but it does not by itself guarantee faithful reproduction of local dynamics. Recent ODE-level studies have shown that energy dissipation alone does not ensure dynamical fidelity for spatially homogeneous phase-field models (X...

The existence and instability of blowing-up steady states for the Shigesada-Kawasaki-Teramoto competition model with cross-diffusion

Diffusion-Based Nanostructure and Self-Healing Characterization of Asphalt Binders Using Molecular Dynamics Simulations

Conventional macroscale and microscale experiments have not fully elucidated the thermodynamical behaviors of asphalt binders’ self-healing, particularly under varying thermal conditions and fracture dimensions, limiting understanding of nanoscale molecular processes. This research quantifies density changes and he...

A colour image encryption method based on a coupled map lattice–elementary cellular automaton neurodynamic chaotic system and dynamic dual-affine substitution-box architecture

Abstract Secure colour image transmission requires encryption schemes in which randomness generation, nonlinear substitution and diffusion are designed as a coherent whole. Conventional coupled map lattice-based methods are often constrained by fixed neighbourhood evolution and limited coupling diversity, while many ch...

Modeling long-range dependencies in knee joint contact mechanics: topology diffusion, global routing, and their hybridization.

Findings indicate that topology diffusion provides a robust foundation, while global routing offers complementary gains in reconstructing clinically relevant high-stress patterns.
