Reduced Basis Multiscale Finite Element Methods for Elliptic Problems
In this paper, we propose reduced basis multiscale finite element methods (RB-MsFEM) for elliptic problems with highly oscillating coefficients. The method is based on multiscale ...

A Multiscale Data-Driven Stochastic Method for Elliptic PDEs with Random Coefficients
In this paper, we propose a multiscale data-driven stochastic method (MsDSM) to study stochastic partial differential equations (SPDEs) in the multiquery setting. This method comb...

A Multiband Semiclassical Model for Surface Hopping Quantum Dynamics
In the paper we derive a semiclassical model for surface hopping allowing quantum dynamical nonadiabatic transition between different potential energy surfaces in which cases the ...
