Stability of the Poincaré constant

Bernoulli, 2023
The article studies stability of the best constant in the Poincaré inequality for the invariant distribution of a reversible diffusion on a smooth manifold. That is, it provides a lower bound for the best constant for a probability measure on the manifold satisfying the Poincaré inequality, in terms of the Wasserstein-1 distance between the push ...

Improvement of Sickle Cell Disease Care Mitigates the Healthcare Utilization Induced by Increased Prevalence: Experience of a Tertiary Pediatric Center

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) has undergone major changes in the last decades. Its prevalence has been steadily increasing and numerous advances have been made in the management of the disease. However, the effect in real‐life setting of these major changes is unknown, particularly in a Canadian environment. Procedure We aimed to assess
