Oesophageal adenocarcinoma (OA) has a dismal survival rate and no routine blood-borne biomarker. Circulating tumour DNA (ctDNA) detection in plasma is an emerging non-invasive OA ctDNA analysis previously been shown to track disease relapse progression. However, little known about how well reflects genetic evolution over time. Two patients with that had undergone sampling at diagnosis longitudi...

In this paper we present new randomized and deterministic algorithms for the classical problem of broadcasting in radio networks with unknown topology. We consider directed n-node radio networks with specified eccentricity D (maximum distance from the source node to any other node). BarYehuda et al. presented an algorithm that for any n-node radio network with eccentricity D completes the broad...

However there is reluctance to perform this surgery in the ...

Two classical theorems of Ghouila-Houri and Berge characterize total unimodularity and balancedness in terms of equitable bicolorings and bicolorings, respectively. In this paper, we prove a bicoloring result that provides a common generalization of these two theorems. A 0; 1 matrix is balanced if it does not contain a square submatrix with exactly two nonzero entries per row and per column suc...

Given a system of equations in a “random” finitely generated subgroup of the braid group, we show how to find a small ordered list of elements in the subgroup, which contains a solution to the equations with a significant probability. Moreover, with a significant probability, the solution will be the first in the list. This gives a probabilistic solution to: the conjugacy problem, the group mem...
