Some variance reduction methods for numerical stochastic homogenization
, 2015 We overview a series of recent works devoted to variance reduction techniques for numerical stochastic homogenization. Numerical homogenization requires solving a set of problems at the micro scale, the so-called corrector problems.

A 1D continuum model for beams with pantographic microstructure: asymptotic micro-macro identification and numerical results [PDF]
, 2018 In the standard asymptotic micro-macro identification theory, starting from a De Saint-Venant cylinder, it is possible to prove that, in the asymptotic limit, only flexible, inextensible, beams can be obtained at the macro-level.

A Multiresolution Strategy for Numerical Homogenization
Applied and Computational Harmonic Analysis, 1995 The work is concerned with a multiresolution strategy for homogenization of differential equations (ordinary and partial). The authors develop an efficient numerical approach which generates the coefficients of the homogenized equation. The multiresolution analysis (MRA), a notion introduction by \textit{Y. Meyer}, is used [Rev. Mat. Iberoam. 8, No. 2,

Localized orthogonal decomposition method for the wave equation with a continuum of scales [PDF]
, 2014 This paper is devoted to numerical approximations for the wave equation with a multiscale character. Our approach is formulated in the framework of the Localized Orthogonal Decomposition (LOD) interpreted as a numerical homogenization with an $L^2 ...

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

He jishuBackgroundThe two-step approach, as the major method in reactor numerical calculation, faces the challenge of accuracy in calculating high-fidelity models because of limitations imposed by simplified assumptions such as assembly homogenization and the ...

DIFFUSION PIECEWISE HOMOGENIZATION VIA FLUX DISCONTINUITY RATIOS
Nuclear Engineering and Technology, 2013 We analyze piecewise homogenization with flux-weighted cross sections and preservation of averaged currents at the boundary of the homogenized domain.

Nonasymptotic Homogenization of Periodic Electromagnetic Structures: Uncertainty Principles
, 2015 We show that artificial magnetism of periodic dielectric or metal/dielectric structures has limitations and is subject to at least two "uncertainty principles". First, the stronger the magnetic response (the deviation of the effective permeability tensor

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
