Testing for Homogeneity in Mixture Models [PDF]
Statistical models of unobserved heterogeneity are typically formalized as mixtures of simple parametric models and interest naturally focuses on testing for homogeneity versus general mixture alternatives.

Homogeneity and h -homogeneity
A topological space \(X\) is \textit{homogeneous} if each of its points can be carried to any other via a homeomorphism of the space; \(X\) is \textit{\(h\)-homogeneous} if it is homeomorphic to each of its nonempty clopen subspaces. The author investigates conditions under which these two notions are related for zero-dimensional spaces. The first main

Functionally Graded Media [PDF]
The notions of uniformity and homogeneity of elastic materials are reviewed in terms of Lie groupoids and frame bundles. This framework is also extended to consider the case Functionally Graded Media, which allows us to obtain some homogeneity conditions.

Simulation analysis of uniformity of optical sphere polishing motion trajectory
In order to improve the processing quality, processing efficiency and reduce the cost wastage of the dome surface, the effect of each motion parameter on the uniformity of material removal from the optical dome surface during the polishing process was ...

Homogeneity of Bilayer Graphene
We present non-linear transport measurements on suspended, current annealed bilayer graphene devices. Using a multi-terminal geometry we demonstrate that devices tend to be inhomogeneous and host two different electronic phases next to each other.

Homogeneity of dynamically defined wild knots [PDF]
In this paper we prove that a wild knot $K$ which is the limit set of a Kleinian group acting conformally on the unit 3-sphere, with its standard metric, is homogeneous: given two points $p, q\in{K}$ there exists a homeomorphism $f$ of the sphere such ...

The Chemical Homogeneity of Sun-like Stars in the Solar Neighborhood [PDF]
The compositions of stars are a critical diagnostic tool for many topics in astronomy such as the evolution of our Galaxy, the formation of planets, and the uniqueness of the Sun.
