Adenomyosis is frequent during the evaluation of infertile women. Present evidence suggests that adenomyosis has a negative impact on female fertility. Limited data from uncontrolled studies suggest that treatment of adenomyosis may improve fertility. This review critically appraises the existing evidence to determine the relationship between adenomyosis and female fertility. ...

We address Anderson localization of light in disordered optical lattices where the disorder strength varies across the transverse direction. Such variation changes the preferred domains where formation of localized eigenmodes is most probable, hence drastically impacting light localization properties. Thus, step-like disorder results in formation of modes with different decay ...
