In this note, we consider the question of classicality for theory which is known to be effective description two-dimensional black holes - Morse quantum mechanics. We calculate Wigner function and Fisher information characterizing classicality/quantumness single-particle systems briefly discuss further directions study.

The recently reported cell-free mitochondria in human blood have been thought to be respiratory competent, giving rise speculation about their biological function(s). By characterizing bioenergetics vitro, we show that circulating are unlikely functional vivo since they display no potential for oxidative phosphorylation.

This note corrects and extends a recent axiomatic characterization of the Orlovsky choice function for a particular class of transitive fuzzy relations. The interest of characterizing choice functions for "well-behaved" fuzzy relations is then discussed.

This note contains two types of functional equations characterizing the conditional probability measures as subclasses of vector measures on general Banach function spaces. One uses the theory of vector integration and the other employs a form of the Sidak identity.
