Due to its numerous important applications[1–5] in the area of quantum information and computation, entanglement has been extensively studied in the past decade. The concept of considering entanglement as a new type of useful resource has been widely accepted. Efforts have been made to quantitatively and qualitatively measure this kind of resource in both bipartite and multipartite cases[6–8]. ...

Comparability between different public examinations in the same and also dzfferent subjects, has been a continuing requirement in the UK. There is a current renewed interest in between-subject comparability, especially at A-level. The present paper examines the assumptions behind attempts to achieve comparability and explores the educational implications of some of the statistical procedures wh...

Background: The study was conducted to examine the comparability of the BMI and Gallagher’s classification in diagnosing obesity based on the cutoff points of the gold standards and to estimate suitable cutoff points for detecting obesity among Iranians.Methods: The cross-sectional study was comparative in nature. The sample consisted of 20,163 adults. The bioelectrical impedance analysis (BIA)...

‎In this paper we prove that a simplicial complex is determined‎ ‎uniquely up to isomorphism by its barycentric subdivision as well as‎ ‎its comparability graph‎. ‎We also put together several algebraic‎, ‎combinatorial and topological invariants of simplicial complexes‎.

A comparability graph is a graph whose edges can be oriented transitively. Given a comparability graph G = (V, E) and an arbitrary edge ê ∈ E we explore the question whether the graph G − ê, obtained by removing the undirected edge ê, is a comparability graph as well. We define a new substructure of implication classes and present a complete mathematical characterization of all those edges.
