TL;DR: A comparison of the strong-field induced absorption spectrum with a numerical integration of the von Neumann equation for a few-level quantum system is supported, confirming the previously observed reduced alignment compared to theoretical predictions.

TL;DR: It is concluded that CRP is equally strongly related torisk of MI and stroke, whereas LDL-C is related to risk of MI but not stroke.

TL;DR: In this paper, an inclusive search is performed for supersymmetry in final states containing jets and an apparent imbalance in transverse momentum, p → T miss, due to the production of unobserved weakly interacting particles in pp collisions at a centre-of-mass energy of 8 TeV.

Abstract: A model-independent search for the production of heavy resonances decaying into top-antitop quark pairs is presented. The search is based on events containing one lepton (muon or electron) and at least two jets selected from data samples corresponding to an integrated luminosity of 4.4-5.0 fb^(−1) collected in pp collisions at s√=7 TeV. Results are presented from the combination of two dedicated searches optimized for boosted production and production at threshold. No excess of events is observed over the expected yield from the standard model processes. Topcolor Z′ bosons with narrow (wide) width are excluded at 95% confidence level for masses below 1.49 (2.04) TeV and an upper limit of 0.3 (1.3) pb or lower is set on the production cross section times branching fraction for resonance masses above 1 TeV. Kaluza-Klein excitations of a gluon with masses below 1.82 TeV (at 95% confidence level) in the Randall-Sundrum model are also excluded, and an upper limit of 0.7 pb or lower is set on the production cross section times branching fraction for resonance masses above 1 TeV.

TL;DR: The purely electroweak (EW) cross section for the production of two jets in association with a Z boson, in proton-proton collisions at √ s = 8 TeV, is measured using data recorded by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 19.7 fb−1.
