Background: Presence of discordance between the Gleason score on needle biopsy and the score of radical prostatectomy specimen is common and universal. In this study, we determined the accuracy of Gleason grading of biopsies in predicting histological grading of radical prostatectomy specimens and the degree of overgrading and undergrading of prostatic adenocarcinoma i...

The chromatic polynomials of certain families of graphs can be calculai ed by a transfer matrix method. The transfer matrix commutes with an action of the symmetric group on the colours. Using représentation theory, it is shown that the matrix is équivalent to a block-diagonal matrix. The multiplicities and the sizes of the blocks are obtained. Using a repeated inclusion-exclusion argument the ...

The behavior at infinity of the Fourier transform of the random measures that appear in the theory of multiplicative chaos of Mandelbrot, Peyrière, and Kahane is an area quite unexplored. For context and further reference, we first present an overview of this theory and then the result, which is the main objective of this work, generalizing a result previously announced by Kahane. We establish ...

this study was aimed at determining intra and inter-observer concordance rates in the gleason scoring of prostatic adenocarcinoma, before and after a web-based educational course. in this self-controlled study, 150 tissue samples of prostatic adenocarcinoma are re-examined to be scored according to the gleason scoring system. then all pathologists attend a free web-based course. afterwards, the...

The Kochen--Specker (KS) theorem reveals the nonclassicality of single quantum systems. In contrast, Bell's and entanglement concern composite Accordingly, unlike incompatibility, Bell non-locality are not necessary to demonstrate KS-contextuality. However, here we find that for multiqubit systems, both essential proofs theorem. Firstly, show unentangled measurements (a strict superset local me...

We introduce a new framework for contextuality based on simplicial sets, combinatorial models of topological spaces that play prominent role in modern homotopy theory. Our approach extends measurement scenarios to consist (rather than sets) measurements and outcomes, thereby generalizes nonsignaling distributions distributions, which are modeled by sets. Using this formalism we present topologi...

The Royal College of Pathologists’ guidelines on the reporting of prostate biopsies were published in October 2009.1 This article reports an audit (in 2010) and re-audit (in 2013) of prostate core biopsies at the University Hospital of North Tees. Our objectives were: • to compare our reporting practices against the standards of the Royal College of Pathologists’ guidelines for quality assuranc...
