New respiratory infections after or while experiencing post-acute infectious syndromes (PAIS) can lead to resurgence of symptoms. Data comparing symptoms, related impairment, and duration of first and recurring PAIS episodes are lacking. This cross-sectional study was conducted i...

Non-uniformly elliptic variational problems on BV

Abstract We establish $$\operatorname {W}^{1,1}$$ W 1 , 1 -regularity and higher gradient integrability for relaxed minimizers of convex integral functionals on $$\operatorname {BV}$$ BV . Unlike classical examples such as the minimal surface integrand, we only require linear gro...
