We study random dynamical systems of certain continuous functions on the unit interval. We use bounded variation to provide sufficient conditions for unique ergodicity of these systems. Several classes of examples are provided.

The celebrated Dvoretzky theorem asserts that every $N$-dimensional convex body admits central sections of dimension $d = \Omega(\log N)$, which is nearly spherical. For many instances of convex bodies, typically unit balls with respect to some norm,

Stochastic dynamical systems consisting of non-invertible continuous maps on an interval are studied. It is proved that if they satisfy the recently introduced so-called $\mu$-injectivity and some mild assumptions, then proximality, asymptotic stabil

We show several variants of concentration inequalities on the sphere stated as subgaussian estimates with optimal constants. For a Lipschitz function, we give one-sided and two-sided bounds for deviation from the median as well as from the mean. For

We obtain sharp estimates for the Jacobi heat kernel in a range of parameters where the result has not been established before. This extends and completes an earlier result due to the authors. The proof is based on a generalization of the Dijksma-Koo

In this short note, we investigate non-invertible stochastic dynamical systems on the unit interval $[0, 1]$. We provide a handy condition for unique ergodicity for systems that are injective in mean. On the other hand, we give concrete examples wher

Eleven possible candidates for compounds of pentavalent praseodymium were investigated with relativistic density functional theory using the B3LYP functional with ZORA scalar relativistic correction and including spin orbit coupling effects. Two of t

Background: Patients with recent acute coronary syndrome (ACS) commonly experience chest pain, which affects quality of life even when not due to recurrence of ACS. This post hoc analysis of ODYSSEY OUTCOMES assessed the effect of alirocumab, a propr

Introduction and Purpose Germ cell tumors of the testis are the most common malignant tumors in young men aged 15-40, although their incidence in the male population is about 1-1.5%. 90-98% of all testicular tumors originate from germ cells. There ha
