Measurements of top-quark pair differential cross-sections in the $$e\mu $$ e μ channel in pp collisions at $$\sqrt{s} = 13$$ s = 13  TeV using the ATLAS detector

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
This article presents measurements of $$t\bar{t}$$ t t ¯ differential cross-sections in a fiducial phase-space region, using an integrated luminosity of 3.2 fb $$^{-1}$$ - 1 of proton–proton data at a centre-of-mass energy of $$\sqrt{s} = 13$$ s = 13 ...

Aridity and grazing are associated with reduced trait complementarity and higher invasion intensity of Solanum rostratum in native plant communities

open access: yesFunctional Ecology, Volume 39, Issue 11, Page 3255-3268, November 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The biotic resistance hypothesis (BRH) of Elton posits that diverse communities are more resistant to biological invasions. While the effects of climatic stresses and human disturbances on community invasibility have been extensively studied individually, their combined

Monitoring transient elastic energy storage within the rotary motors of single FoF1-ATP synthase by DCO-ALEX FRET

open access: yes, 2012
The enzyme FoF1-ATP synthase provides the 'chemical energy currency' adenosine triphosphate (ATP) for living cells. Catalysis is driven by mechanochemical coupling of subunit rotation within the enzyme with conformational changes in the three ATP binding

Erratum to: Measurement of the W boson polarisation in $$t\bar{t}$$ tt¯ events from pp collisions at $$\sqrt{s} = 8~\hbox {TeV}$$ s=8TeV in the lepton + jets channel with ATLAS

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
This change does not have any impact on the measured helicity fractions, but it changes the obtained limits on the anomalous couplings.

The future of sovereignty in multilevel governance Europe: a constructivist reading [PDF]

open access: yes, 2004
Multilevel governance presents a depiction of contemporary structures in EU Europe as consisting of overlapping authorities and competing competencies. By focusing on emerging non-anarchical structures in the international system, hence moving beyond the

Measurement of the inclusive cross-sections of single top-quark and top-antiquark t-channel production in pp collisions at s = 13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
A measurement of the t-channel single-top-quark and single-top-antiquark production cross-sections in the lepton+jets channel is presented, using 3.2 fb−1 of proton-proton collision data at a centre-of-mass energy of 13 TeV, recorded with the ATLAS ...

Resonant scattering by magnetic impurities as a model for spin relaxation in bilayer graphene [PDF]

open access: yes, 2015
We propose that the observed spin-relaxation in bilayer graphene is due to resonant scattering by magnetic impurities. We analyze a resonant scattering model due to adatoms on both dimer and non-dimer sites, finding that only the former give narrow ...

Measurement of jet activity produced in top-quark events with an electron, a muon and two b-tagged jets in the final state in pp collisions at $$\sqrt{s}=13$$ s = 13 TeV with the ATLAS detector

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
Measurements of jet activity in top-quark pair events produced in proton–proton collisions are presented, using 3.2 fb $$^{-1}$$ - 1 of pp collision data at a centre-of-mass energy of 13 TeV collected by the ATLAS experiment at the Large Hadron Collider.

A Modern Look at Freedman's Box Model [PDF]

open access: yes, 2019
This paper revisits the box model, a metaphor developed by David Freedman to explain sampling distributions and  statistical inference to introductory statistics students. The basic idea is to represent all random phenomena in terms of drawing tickets at

Analyzing conformational changes in single FRET-labeled A1 parts of archaeal A1AO-ATP synthase

open access: yes, 2018
ATP synthases utilize a proton motive force to synthesize ATP. In reverse, these membrane-embedded enzymes can also hydrolyze ATP to pump protons over the membrane.
