    The article discusses one of the variants of overlap syndrome – a combination of symptoms of ankylosing spondylitis (AS) and rheumatoid arthritis (RA). Three clinical cases are described, in these cases characteristic signs of both diseases were noted and the criteria of both diseases were met. The genetic factors and immunopathogenetic mechanisms underlying AS and RA are analyzed. A review of the literature on the combination of AS and RA is presented.В статье рассмотрен один из вариантов перекрестных (overlap) синдромов – сочетание симптоматики анкилозирующего спондилита (АС) и ревматоидного артрита (РА). Описаны три клинических наблюдения, в которых отмечались характерные признаки обоих заболеваний и соответствие критериям обоих диагнозов. Проанализированы генетические факторы и иммунопатогенетические механизмы, лежащие в основе АС и РА. Представлен обзор литературы, посвященной сочетанию АС и РА

    This paper presents measurements of the W+μ+νW^+ \rightarrow \mu^+\nu and WμνW^- \rightarrow \mu^-\nu cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.
