Homogenization of Non-symmetric Convolution Type Operators

The paper studies homogenization problem for a bounded in $$L_2(\mathbb {R}^d)$$ convolution type operator $${\mathbb {A}}_\varepsilon $$ , $$\varepsilon >0$$ , of the form $$\begin{aligned} ({\mathbb {A}}_\varepsilon u) ({\textbf{x}}) = \varepsilon ^{-d-2} \int _{\mathbb {R}^d}...

No impact of parity on global gene expression levels in breast cancer tissue and normal breast tissue – a nested case-control study in the Norwegian Women and Cancer study

Abstract Background We have previously demonstrated that the linear decrease in postmenopausal breast cancer incidence with increasing parity is linked to expression changes in hundreds of genes in the peripheral blood cells of healthy women. However, these changes are not observ...
