Multiscale discontinuous Petrov–Galerkin method for the multiscale elliptic problems [PDF]

Numerical Methods for Partial Differential Equations, 2017
In this article, we present a new multiscale discontinuous Petrov–Galerkin method (MsDPGM) for multiscale elliptic problems. This method utilizes the classical oversampling multiscale basis in the framework of a Petrov–Galerkin version of the discontinuous Galerkin method, allowing us to better cope with multiscale features in the solution.

An Iterative Method for Problems with Multiscale Conductivity [PDF]

Computational and Mathematical Methods in Medicine, 2012
A model with its conductivity varying highly across a very thin layer will be considered. It is related to a stable phantom model, which is invented to generate a certain apparent conductivity inside a region surrounded by a thin cylinder with holes. The thin cylinder is an insulator and both inside and outside the thin cylinderare filled with the same

Nonlinear Analytical Design of Nonlinear Tuned Mass Dampers and Nonlinear Primary Structures Based on Complex Variable Averaging and Multiscale Methods

Buildings
With the development of modern structures in the direction of higher and more complexity, the existence of multiple factors in the design and requirements of structures can lead to structures prone to nonlinear properties.

A Multiscale Finite Element Method for the Schrödinger Equation with Multiscale Potentials [PDF]

SIAM Journal on Scientific Computing, 2019
In recent years, an increasing attention has been paid to quantum heterostructures with tailored functionalities, such as heterojunctions and quantum matematerials, in which quantum dynamics of electrons can be described by the Schrödinger equation with multiscale potentials.

Shape classification via image-based multiscale description [PDF]

, 2011
We introduce a new multiscale Fourier-based object description in 2-D space using a low-pass Gaussian filter (LPGF) and a high-pass Gaussian filter (HPGF), separately.

Visualizing the multidimensional landscape of biological variation in modern microscopy

Frontiers in Bioinformatics
Variation is a foundational biological principle that has historically been marginalized—both due to limited experimental accessibility and because of idealized, stereotypic blueprints rooted in essentialist thinking.

An Adaptive Multiscale Finite Element Method [PDF]

Multiscale Modeling & Simulation, 2014
This work is devoted to an adaptive multiscale finite element method (MsFEM) for solving elliptic problems with rapidly oscillating coeefficients. Starting from a general version of the MsFEM with oversampling, we de- rive an a posteriori estimate for the H1-error between the exact solution of the problem and a corresponding MsFEM approximation.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
