On Decay Centrality

open access: yesThe B.E. Journal of Theoretical Economics, 2017
AbstractWe establish a relationship between decay centrality and two widely used measures of centrality, namely degree and closeness. We show that for low values of the decay parameter the nodes with maximum decay centrality also have maximum degree, whereas for high values of the decay parameter they also maximize closeness.

Is a hollow centralizer necessary when using a polished, tapered, cemented femoral stem?: A randomized, controlled RSA study of 60 hips with 10 years of follow-up

open access: yesActa Orthopaedica, 2017
Background and purpose — A tapered, polished and collarless stem is normally equipped with a hollow centralizer to prevent the stem from becoming end-bearing in the cement as the stem subsides. In a randomized clinical trial, we evaluated such a stem (MS-

Complete parts and subhypergroups in reversible regular hypergroups

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
In this paper we analyse the center and centralizer of an element in the context of reversible regular hypergroups, in order to obtain the class equation in regular reversible hypergroups, by using complete parts.

Is Bank Supervision Central to Central Banking? [PDF]

open access: yesThe Quarterly Journal of Economics, 1999
Whether central banks should play an active role in bank supervision and regulation is being debated both in the United States and abroad. While the Bank of England has recently been stripped of its supervisory responsibilities and several proposals in the United States have advocated removing bank supervision from the Federal Reserve System, other ...

The Characterization of Generalized Jordan Centralizers on Triangular Algebras

open access: yesJournal of Function Spaces, 2018
In this paper, it is shown that if T=Tri(A,M,B) is a triangular algebra and ϕ is an additive operator on T such that (m+n+k+l)ϕ(T2)-(mϕ(T)T+nTϕ(T)+kϕ(I)T2+lT2ϕ(I))∈FI for any T∈T, then ϕ is a centralizer. It follows that an (m,n)- Jordan centralizer on a
