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 spa...

Digital technology adoption and relative health deprivation: evidence from China
The rapid expansion of digital technologies has sparked debate over whether they exacerbate or alleviate existing health inequalities, yet empirical evidence from developing countries remains inconclusive. This study investigates the association between digital technology adoptio...

A Residual Driven Multiscale Method for Darcy’s Flow in Perforated Domains
In this paper, we present a residual-driven multiscale method for simulating Darcy flow in perforated domains, where complex geometries and highly heterogeneous permeability make direct simulations computationally expensive. To address this, we introduce a velocity-pressure elimi...
