Advanced Science, EarlyView.We developed a RhPd‐H nanozyme that integrates enhanced POD‐mimetic catalytic activity with thermally triggered H2 release. H2 shields and reprograms mitochondria to continuously leak endogenous ·O2−. This dual‐path ROS spatially and temporally disrupts redox homeostasis, inducing persistent oxidative stress for tumor suppression and antitumor immunity,

Virtual Element Methods for hyperbolic problems on polygonal meshes [PDF]
, 2016 In the present paper we develop the Virtual Element Method for hyperbolic problems on polygonal meshes, considering the linear wave equations as our model problem. After presenting the semi-discrete scheme, we derive the convergence estimates in H^1 semi-

Temporal Interference Stimulation Enhances Neural Regeneration
Advanced Science, EarlyView.Temporal interference (TI) stimulation is proposed as a non‐invasive approach to enhance neural regeneration in the deep brain. Theta‐band TI modulation selectively promotes neural progenitor cell differentiation in vitro and augments hippocampal neurogenesis in amouse model of Alzheimer's disease‐like amyloidosis.

Mimetic finite differences for nonlinear and control problems
Mathematical Models and Methods in Applied Sciences, 2014 In this paper we review some recent applications of the mimetic finite difference method to nonlinear problems (variational inequalities and quasilinear elliptic equations) and optimal control problems governed by linear elliptic partial differential equations. Several numerical examples show the effectiveness of mimetic finite differences in building

Parametric Analysis of Spiking Neurons in 16 nm Fin Field‐Effect Transistor Technology
Advanced Intelligent Discovery, EarlyView.Energy efficient computing has driven a shift toward brain‐inspired neuromorphic hardware. This study explores the design of three distinct silicon neuron topologies implemented in 16 nm fin field‐Effect transistor technology. While the Axon‐Hillock design achieves gigahertz throughput, its functional fragility persists. The Morris–Lecar model captures

Mixed Mimetic Spectral Element method applied to Darcy's problem
, 2013 We present a discretization for Darcy's problem using the recently developed Mimetic Spectral Element Method. The gist lies in the exact discrete representation of integral relations.

Mimetic Finite Difference Method for Shape Optimization Problems
, 2014 We test the performance of the Mimetic Finite Difference method applied to a wide class of shape optimization problems. Adaptive strategies based on heuristic error indicators are also considered to validate the effectiveness of the numerical scheme.

Mimetic finite difference approximation of quasilinear elliptic problems
Calcolo, 2014 The authors consider the following quasilinear elliptic problem \[ -\mathrm{div} (\kappa (|\nabla u|^2)\nabla u)=f \quad \text{in}\, \Omega, \qquad u=0\quad \text{on}\, \partial \Omega , \tag{1} \] where \(f\) is a given function and \(\Omega\) is an open, bounded set of \(\mathbb{R}^2\) with boundary \(\partial \Omega\).

A Stable Mimetic Finite-Difference Method for Convection-Dominated Diffusion Equations
SIAM Journal on Scientific Computing, 2023 Convection-diffusion equations arise in a variety of applications such as particle transport, electromagnetics, and magnetohydrodynamics. Simulation of the convection-dominated regime for these problems, even with high-fidelity techniques, is particularly challenging due to the presence of sharp boundary layers and shocks causing jumps and ...
