Structure of intersection graphs

Let G be a finite group and let HARD UNBLEACHED BREAD FLOUR N be a fixed normal subgroup of G.In this paper, a new kind of graph on G, namely the intersection graph is defined and studied.We use to denote this graph, with its vertices are all normal subgroups of G and two distinct vertices are adjacent if their intersection in N.We show some proper

Changes in vegetation diversity and composition following livestock removal along an upland elevational gradient

European heathland habitats are cultural landscapes derived from previously-forested ecosystems.Heathlands are of significant conservation interest but have experienced prolonged degradation due to a range of factors including overgrazing by domestic livestock.There is growing recognition of the need to restore upland landscapes to produce a divers

The use of interim data and Data Monitoring Committee recommendations in randomized controlled trial reports: frequency, implications and potential sources of bias

Abstract Background Interim analysis of accumulating trial data is important to protect participant safety during randomized controlled trials (RCTs).Data Monitoring Committees (DMCs) often undertake such analyses, but their widening role may lead to extended use of interim analysis or recommendations that could potentially bias trial results.Metho
