Adipose tissue and myosteatosis measured by artificial intelligence as a predictor of overall survival in bladder cancer

Body composition may influence outcomes in muscle-invasive bladder cancer (MIBC), but its prognostic role remains unclear. In particular, the impact of adipose tissue distribution and muscle quality beyond BMI has been insufficiently studied. This study aimed to evaluate whether...

Flat Left-Invariant Lorentzian Metrics on Almost Abelian Lie Groups

Abstract Almost abelian Lie groups are those admitting a normal subgroup which is commutative and of codimension one. We determine all Lie algebras of almost abelian Lie groups admitting a left-invariant Lorentzian metric of vanishing curvature. For each of those algebras, we com...
